Invariant 1 ensures that + * the property of being able to run script propagates up the callstack. There + * is an opt-out for invariant 1: A function (declaration _or_ implementation) + * can be decorated with MOZ_CAN_RUN_SCRIPT_BOUNDARY to indicate that we do not + * require it or any of its callers to be MOZ_CAN_RUN_SCRIPT even if it calls + * MOZ_CAN_RUN_SCRIPT functions. + * + * There are two known holes in invariant 1, apart from the + * MOZ_CAN_RUN_SCRIPT_BOUNDARY opt-out: + * + * - Functions called via function pointers can be MOZ_CAN_RUN_SCRIPT even if + * their caller is not, because we have no way to determine from the function + * pointer what function is being called. + * - MOZ_CAN_RUN_SCRIPT destructors can happen in functions that are not + * MOZ_CAN_RUN_SCRIPT. + * https://bugzilla.mozilla.org/show_bug.cgi?id=1535523 tracks this. + * + * Given those invariants we then require that when calling a MOZ_CAN_RUN_SCRIPT + * function all refcounted arguments (including "this") satisfy one of these + * conditions: + * a) The argument is held via a strong pointer on the stack. + * b) The argument is a const strong pointer member of "this".

It is +targeted at people wanting to learn about internals of the build system. +It is not meant for persons who casually interact with the build system. +That being said, knowledge empowers, so consider reading on. + +The build system is composed of many different components working in +harmony to build the source tree. We begin with a graphic overview. + +.. graphviz:: + + digraph build_components { + rankdir="LR"; + "configure" -> "config.status" -> "build backend" -> "build output" + } + +Phase 1: Configuration +====================== + +Phase 1 centers around the ``configure`` script, which is a bash shell script. +The file is generated from a file called ``configure.in`` which is written in M4 +and processed using Autoconf 2.13 to create the final configure script. +You don't have to worry about how you obtain a ``configure`` file: the build +system does this for you. + +The primary job of ``configure`` is to determine characteristics of the system +and compiler, apply options passed into it, and validate everything looks OK to +build. The primary output of the ``configure`` script is an executable file +in the object directory called ``config.status``. ``configure`` also produces +some additional files (like ``autoconf.mk``). However, the most important file +in terms of architecture is ``config.status``. + +The existence of a ``config.status`` file may be familiar to those who have worked +with Autoconf before. However, Mozilla's ``config.status`` is different from almost +any other ``config.status`` you've ever seen: it's written in Python! Instead of +having our ``configure`` script produce a shell script, we have it generating +Python. + +Now is as good a time as any to mention that Python is prevalent in our build +system. If we need to write code for the build system, we do it in Python. +That's just how we roll. For more, see :ref:`python`. + +``config.status`` contains 2 parts: data structures representing the output of +``configure`` and a command-line interface for preparing/configuring/generating +an appropriate build backend. (A build backend is merely a tool used to build +the tree - like GNU Make or Tup). These data structures essentially describe +the current state of the system and what the existing build configuration looks +like. For example, it defines which compiler to use, how to invoke it, which +application features are enabled, etc. You are encouraged to open up +``config.status`` to have a look for yourself! + +Once we have emitted a ``config.status`` file, we pass into the realm of +phase 2. + +Phase 2: Build Backend Preparation and the Build Definition +=========================================================== + +Once ``configure`` has determined what the current build configuration is, +we need to apply this to the source tree so we can actually build. + +What essentially happens is the automatically-produced ``config.status`` Python +script is executed as soon as ``configure`` has generated it. ``config.status`` +is charged with the task of tell a tool how to build the tree. To do this, +``config.status`` must first scan the build system definition. + +The build system definition consists of various ``moz.build`` files in the tree. +There is roughly one ``moz.build`` file per directory or per set of related directories. +Each ``moz.build`` files defines how its part of the build config works. For +example it says *I want these C++ files compiled* or *look for additional +information in these directories.* config.status starts with the ``moz.build`` +file from the root directory and then descends into referenced ``moz.build`` +files by following ``DIRS`` variables or similar. + +As the ``moz.build`` files are read, data structures describing the overall +build system definition are emitted. These data structures are then fed into a +build backend, which then performs actions, such as writing out files to +be read by a build tool. e.g. a ``make`` backend will write a +``Makefile``. + +When ``config.status`` runs, you'll see the following output:: + + Reticulating splines... + Finished reading 1096 moz.build files into 1276 descriptors in 2.40s + Backend executed in 2.39s + 2188 total backend files. 0 created; 1 updated; 2187 unchanged + Total wall time: 5.03s; CPU time: 3.79s; Efficiency: 75% + +What this is saying is that a total of *1096* ``moz.build`` files were read. +Altogether, *1276* data structures describing the build configuration were +derived from them. It took *2.40s* wall time to just read these files and +produce the data structures. The *1276* data structures were fed into the +build backend which then determined it had to manage *2188* files derived +from those data structures. Most of them already existed and didn't need +changed. However, *1* was updated as a result of the new configuration. +The whole process took *5.03s*. Although, only *3.79s* was in +CPU time. That likely means we spent roughly *25%* of the time waiting on +I/O. + +For more on how ``moz.build`` files work, see :ref:`mozbuild-files`. + +Phase 3: Invocation of the Build Backend +======================================== + +When most people think of the build system, they think of phase 3. This is +where we take all the code in the tree and produce Firefox or whatever +application you are creating. Phase 3 effectively takes whatever was +generated by phase 2 and runs it. Since the dawn of Mozilla, this has been +make consuming Makefiles. However, with the transition to moz.build files, +you may soon see non-Make build backends, such as Tup or Visual Studio. + +When building the tree, most of the time is spent in phase 3.

Toolbars, +menu bars, progress bars, and window title bars are all examples of +elements that are typically part of the chrome. + +``chrome.manifest`` files are used to register XPCOM components and sources for the chrome protocol. +Every application supplies a root ``chrome.manifest`` file that Mozilla reads on startup. + +Chrome providers +---------------- + +A supplier of chrome for a given window type (e.g., for the browser +window) is called a chrome provider. The providers work together to +supply a complete set of chrome for a particular window, from the images +on the toolbar buttons to the files that describe the text, content, and +appearance of the window itself. + +There are three basic types of chrome providers: + +Content + The main source file for a window description comes from the content + provider, and it can be any file type viewable from within Mozilla. + It will typically be a XUL file, since XUL is designed for describing + the contents of windows and dialogs. The JavaScript files that define + the user interface are also contained within the content packages. + +Locale + Localizable applications keep all their localized information in + locale providers and Fluent FTL files, which are handled separately. + This allows translators to plug in a different + chrome package to translate an application without altering the rest + of the source code. In a chrome provider, localizable files are mostly + Java-style properties files. +Skin + A skin provider is responsible for providing a complete set of files + that describe the visual appearance of the chrome. Typically a skin + provider will provide CSS files and + images. + +The chrome registry +------------------- + +The Gecko runtime maintains a service known as the chrome registry that +provides mappings from chrome package names to the physical location of +chrome packages on disk. + +This chrome registry is configurable and persistent, and thus a user can +install different chrome providers, and select a preferred skin and +locale. This is accomplished through xpinstall and the extension +manager. + +In order to inform the chrome registry of the available chrome, a text +manifest is used: this manifest is "chrome.manifest" in the root of an +extension, or theme, or XULRunner application. + +The plaintext chrome manifests are in a simple line-based format. Each +line is parsed individually; if the line is parsable the chrome registry +takes the action identified by that line, otherwise the chrome registry +ignores that line (and prints a warning message in the runtime error +console). + +.. code:: text + + locale packagename localename path/to/files + skin packagename skinname path/to/files + +.. note:: + + The characters @ # ; : ? / are not allowed in the + packagename. + +Manifest instructions +--------------------- + +comments +~~~~~~~~ + +.. code:: text + + # this line is a comment - you can put here whatever you want + +A line is a comment if it begins with the character '#'. Any following +character in the same line is ignored. + +manifest +~~~~~~~~ + +:: + + manifest subdirectory/foo.manifest [flags] + +This will load a secondary manifest file. This can be useful for +separating component and chrome registration instructions, or separate +platform-specific registration data. + +component +~~~~~~~~~ + +:: + + component {00000000-0000-0000-0000-000000000000} components/mycomponent.js [flags] + +Informs Mozilla about a component CID implemented by an XPCOM component +implemented in JavaScript (or another scripting language, if +applicable).

Typically a contract ID will be paired with a component +entry immediately preceding. + +category +~~~~~~~~ + +:: + + category category entry-name value [flags] + +Registers an entry in the `category manager`. The +specific format and meaning of category entries depend on the category. + +content +~~~~~~~ + +A content package is registered with the line: + +:: + + content packagename uri/to/files/ [flags] + +This will register a location to use when resolving the URI +``chrome://packagename/content/...``. The URI may be absolute or +relative to the location of the manifest file. Note: it must end with a +'/'. + +locale +~~~~~~ + +A locale package is registered with the line: + +.. code:: text + + locale packagename localename uri/to/files/ [flags] + +This will register a locale package when resolving the URI +chrome://*packagename*/locale/... . The *localename* is usually a plain +language identifier "en" or a language-country identifier "en-US". If +more than one locale is registered for a package, the chrome registry +will select the best-fit locale using the user's preferences. + +skin +~~~~ + +A skin package is registered with the line: + +.. code:: text + + skin packagename skinname uri/to/files/ [flags] + +This will register a skin package when resolving the URI +chrome://packagename/skin/... . The *skinname* is an opaque string +identifying an installed skin. If more than one skin is registered for a +package, the chrome registry will select the best-fit skin using the +user's preferences. + +style +~~~~~ + +Style overlays (custom CSS which will be applied to a chrome page) are +registered with the following syntax: + +.. code:: text + + style chrome://URI-to-style chrome://stylesheet-URI [flags] + +override +~~~~~~~~ + +In some cases an extension or embedder may wish to override a chrome +file provided by the application or XULRunner. In order to allow for +this, the chrome registration manifest allows for "override" +instructions: + +.. code:: text + + override chrome://package/type/original-uri.whatever new-resolved-URI [flags] + +Note: overrides are not recursive (so overriding +chrome://foo/content/bar/ with file:///home/john/blah/ will not usually +do what you want or expect it to do). Also, the path inside overridden +files is relative to the overridden path, not the original one (this can +be annoying and/or useful in CSS files, for example). + +.. _chrome_manifest_resource: + +resource +~~~~~~~~ + +Aliases can be created using the ``resource`` instruction: + +.. code:: text + + resource aliasname uri/to/files/ [flags] + +This will create a mapping for ``resource://<aliasname>/`` URIs to the +path given. + +.. note:: + + **Note:** There are no security restrictions preventing web content + from including content at resource: URIs, so take care what you make + visible there. + +Manifest flags +-------------- + +Manifest lines can have multiple, space-delimited flags added at the end +of the registration line. These flags mark special attributes of chrome +in that package, or limit the conditions under which the line is used. + +application +~~~~~~~~~~~ + +Extensions may install into multiple applications. There may be chrome +registration lines which only apply to one particular application. The +flag + +.. code:: text + + application=app-ID + +indicates that the instruction should only be applied if the extension +is installed into the application identified by *app-ID*. Multiple +application flags may be included on a single line, in which case the +line is applied if any of the flags match. + +This example shows how a different overlay can be used for different +applications: + +:: + + overlay chrome://browser/content/browser.xul chrome://myaddon/content/ffOverlay.xul application={ec8030f7-c20a-464f-9b0e-13a3a9e97384} + overlay chrome://messenger/content/mailWindowOverlay.xul chrome://myaddon/content/tbOverlay.xul application={3550f703-e582-4d05-9a08-453d09bdfdc6} + overlay chrome://songbird/content/xul/layoutBaseOverlay.xul chrome://myaddon/content/sbOverlay.xul application=songbird@songbirdnest.com + +appversion +~~~~~~~~~~ + +Extensions may install into multiple versions of an application. There +may be chrome registration lines which only apply to a particular +application version. The flag + +.. code:: text + + appversion=version + appversion<version + appversion<=version + appversion>version + appversion>=version + +indicates that the instruction should only be applied if the extension +is installed into the application version identified. Multiple +``appversion`` flags may be included on a single line, in which case the +line is applied if any of the flags match. The version string must +conform to the `Toolkit version format`. + +platformversion +~~~~~~~~~~~~~~~ + +When supporting more then one application, it is often more convenient +for an extension to specify which Gecko version it is compatible with. +This is particularly true for binary components. If there are chrome +registration lines which only apply to a particular Gecko version, the +flag + +.. code:: text + + platformversion=version + platformversion<version + platformversion<=version + platformversion>version + platformversion>=version + +indicates that the instruction should only be applied if the extension +is installed into an application using the Gecko version identified. +Multiple ``platformversion`` flags may be included on a single line, in +which case the line is applied if any of the flags match. + +contentaccessible +~~~~~~~~~~~~~~~~~ + +Chrome resources can no longer be referenced from within <img>, +<script>, or other elements contained in, or added to, content that was +loaded from an untrusted source. This restriction applies to both +elements defined by the untrusted source and to elements added by +trusted extensions. If such references need to be explicitly allowed, +set the ``contentaccessible`` flag to ``yes`` to obtain the behavior +found in older versions of Firefox. See +`bug 436989 <https://bugzilla.mozilla.org/show_bug.cgi?id=436989>`__. + +The ``contentaccessible`` flag applies only to content packages: it is +not recognized for locale or skin registration. However, the matching +locale and skin packages will also be exposed to content. + +**n.b.:** Because older versions of Firefox do not understand the +``contentaccessible`` flag, any extension designed to work with both +Firefox 3 and older versions of Firefox will need to provide a fallback. +For example: + +:: + + content packagename chrome/path/ + content packagename chrome/path/ contentaccessible=yes + +os +~~ + +Extensions (or themes) may offer different features depending on the +operating system on which Firefox is running. The value is compared to +the value of `OS_TARGET` for the platform. + +.. code:: text + + os=WINNT + os=Darwin + +osversion +~~~~~~~~~ + +An extension or theme may need to operate differently depending on which +version of an operating system is running. For example, a theme may wish +to adopt a different look on Mac OS X 10.5 than 10.4: + +.. code:: text + + osversion>=10.5 + +abi +~~~ + +If a component is only compatible with a particular ABI, it can specify +which ABI/OS by using this directive. The value is taken from the +`nsIXULRuntime` OS and +XPCOMABI values (concatenated with an underscore). For example: + +:: + + binary-component component/myLib.dll abi=WINNT_x86-MSVC + binary-component component/myLib.so abi=Linux_x86-gcc3 + +platform (Platform-specific packages) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Some packages are marked with a special flag indicating that they are +platform specific. Some parts of content, skin, and locales may be +different based on the platform being run. These packages contain three +different sets of files, for Windows and OS/2, Macintosh, and Unix-like +platforms. For example, the order of the "OK" and "Cancel" buttons in a +dialog is different, as well as the names of some items. + +The "platform" modifier is only parsed for content registration; it is +not recognized for locale or skin registration. However, it applies to +content, locale, and skin parts of the package, when specified. + +process +~~~~~~~ + +In electrolysis registrations can be set to only apply in either the +main process or any content processes. The "process" flag selects +between these two.

This document describes the +basics of defining what is going to be built and how. All the following +describes constructs to use in moz.build files. + + +Source files +============ + +Source files to be used in a given directory are registered in the ``SOURCES`` +and ``UNIFIED_SOURCES`` variables. ``UNIFIED_SOURCES`` have a special behavior +in that they are aggregated by batches of 16, requiring, for example, that there +are no conflicting variables in those source files. + +``SOURCES`` and ``UNIFIED_SOURCES`` are lists which must be appended to, and +each append requires the given list to be alphanumerically ordered. + +.. code-block:: python + + UNIFIED_SOURCES += [ + 'FirstSource.cpp', + 'SecondSource.cpp', + 'ThirdSource.cpp', + ] + + SOURCES += [ + 'OtherSource.cpp', + ] + +``SOURCES`` and ``UNIFIED_SOURCES`` can contain a mix of different file types, +for C, C++, and Objective C. + + +Static Libraries +================ + +To build a static library, other than defining the source files (see above), one +just needs to define a library name with the ``Library`` template. + +.. code-block:: python + + Library('foo') + +The library file name will be ``libfoo.a`` on UNIX systems and ``foo.lib`` on +Windows. + +If the static library needs to aggregate other static libraries, a list of +``Library`` names can be added to the ``USE_LIBS`` variable. Like ``SOURCES``, it +requires the appended list to be alphanumerically ordered. + +.. code-block:: python + + USE_LIBS += ['bar', 'baz'] + +If there are multiple directories containing the same ``Library`` name, it is +possible to disambiguate by prefixing with the path to the wanted one (relative +or absolute): + +.. code-block:: python + + USE_LIBS += [ + '/path/from/topsrcdir/to/bar', + '../relative/baz', + ] + +Note that the leaf name in those paths is the ``Library`` name, not an actual +file name. + +Note that currently, the build system may not create an actual library for +static libraries. It is an implementation detail that shouldn't need to be +worried about. + +As a special rule, ``USE_LIBS`` is allowed to contain references to shared +libraries. In such cases, programs and shared libraries linking this static +library will inherit those shared library dependencies. + + +Intermediate (Static) Libraries +=============================== + +In many cases in the tree, static libraries are built with the only purpose +of being linked into another, bigger one (like libxul). Instead of adding all +required libraries to ``USE_LIBS`` for the bigger one, it is possible to tell +the build system that the library built in the current directory is meant to +be linked to that bigger library, with the ``FINAL_LIBRARY`` variable. + +.. code-block:: python + + FINAL_LIBRARY = 'xul' + +The ``FINAL_LIBRARY`` value must match a unique ``Library`` name somewhere +in the tree. + +As a special rule, those intermediate libraries don't need a ``Library`` name +for themselves. + + +Shared Libraries +================ + +Sometimes, we want shared libraries, a.k.a. dynamic libraries. Such libraries +are defined similarly to static libraries, using the ``SharedLibrary`` template +instead of ``Library``. + +.. code-block:: python + + SharedLibrary('foo') + +When this template is used, no static library is built. See further below to +build both types of libraries. + +With a ``SharedLibrary`` name of ``foo``, the library file name will be +``libfoo.dylib`` on OSX, ``libfoo.so`` on ELF systems (Linux, etc.), and +``foo.dll`` on Windows. On Windows, there is also an import library named +``foo.lib``, used on the linker command line. ``libfoo.dylib`` and +``libfoo.so`` are considered the import library name for, resp. OSX and ELF +systems. + +On OSX, one may want to create a special kind of dynamic library: frameworks. +This is done with the ``Framework`` template. + +.. code-block:: python + + Framework('foo') + +With a ``Framework`` name of ``foo``, the framework file name will be ``foo``. +This template however affects the behavior on all platforms, so it needs to +be set only on OSX. + + +Executables +=========== + +Executables, a.k.a. programs, are, in the simplest form, defined with the +``Program`` template. + +.. code-block:: python + + Program('foobar') + +On UNIX systems, the executable file name will be ``foobar``, while on Windows, +it will be ``foobar.exe``. + +Like static and shared libraries, the build system can be instructed to link +libraries to the executable with ``USE_LIBS``, listing various ``Library`` +names. + +In some cases, we want to create an executable per source file in the current +directory, in which case we can use the ``SimplePrograms`` template + +.. code-block:: python + + SimplePrograms([ + 'FirstProgram', + 'SecondProgram', + ]) + +Contrary to ``Program``, which requires corresponding ``SOURCES``, when using +``SimplePrograms``, the corresponding ``SOURCES`` are implied. If the +corresponding ``sources`` have an extension different from ``.cpp``, it is +possible to specify the proper extension: + +.. code-block:: python + + SimplePrograms([ + 'ThirdProgram', + 'FourthProgram', + ], ext='.c') + +Please note this construct was added for compatibility with what already lives +in the mozilla tree ; it is recommended not to add new simple programs with +sources with a different extension than ``.cpp``. + +Similar to ``SimplePrograms``, is the ``CppUnitTests`` template, which defines, +with the same rules, C++ unit tests programs. Like ``SimplePrograms``, it takes +an ``ext`` argument to specify the extension for the corresponding ``SOURCES``, +if it's different from ``.cpp``. + + +Linking with system libraries +============================= + +Programs and libraries usually need to link with system libraries, such as a +widget toolkit, etc. Those required dependencies can be given with the +``OS_LIBS`` variable. + +.. code-block:: python + + OS_LIBS += [ + 'foo', + 'bar', + ] + +This expands to ``foo.lib bar.lib`` when building with MSVC, and +``-lfoo -lbar`` otherwise. + +For convenience with ``pkg-config``, ``OS_LIBS`` can also take linker flags +such as ``-L/some/path`` and ``-llib``, such that it is possible to directly +assign ``LIBS`` variables from ``CONFIG``, such as: + +.. code-block:: python + + OS_LIBS += CONFIG['MOZ_PANGO_LIBS'] + +(assuming ``CONFIG['MOZ_PANGO_LIBS']`` is a list, not a string) + +Like ``USE_LIBS``, this variable applies to static and shared libraries, as +well as programs. + + +Libraries from third party build system +======================================= + +Some libraries in the tree are not built by the moz.build-governed build +system, and there is no ``Library`` corresponding to them. + +However, ``USE_LIBS`` allows to reference such libraries by giving a full +path (like when disambiguating identical ``Library`` names). The same naming +rules apply as other uses of ``USE_LIBS``, so only the library name without +prefix and suffix shall be given. + +.. code-block:: python + + USE_LIBS += [ + '/path/from/topsrcdir/to/third-party/bar', + '../relative/third-party/baz', + ] + +Note that ``/path/from/topsrcdir/to/third-party`` and +``../relative/third-party/baz`` must lead under a subconfigured directory (a +directory with an AC_OUTPUT_SUBDIRS in configure.in), or ``security/nss``. + + +Building both static and shared libraries +========================================= + +When both types of libraries are required, one needs to set both +``FORCE_SHARED_LIB`` and ``FORCE_STATIC_LIB`` boolean variables. + +.. code-block:: python + + FORCE_SHARED_LIB = True + FORCE_STATIC_LIB = True + +But because static libraries and Windows import libraries have the same file +names, either the static or the shared library name needs to be different +than the name given to the ``Library`` template. + +The ``STATIC_LIBRARY_NAME`` and ``SHARED_LIBRARY_NAME`` variables can be used +to change either the static or the shared library name. + +.. code-block:: python + + Library('foo') + STATIC_LIBRARY_NAME = 'foo_s' + +With the above, on Windows, ``foo_s.lib`` will be the static library, +``foo.dll`` the shared library, and ``foo.lib`` the import library. + +In some cases, for convenience, it is possible to set both +``STATIC_LIBRARY_NAME`` and ``SHARED_LIBRARY_NAME``. For example: + +.. code-block:: python + + Library('mylib') + STATIC_LIBRARY_NAME = 'mylib_s' + SHARED_LIBRARY_NAME = CONFIG['SHARED_NAME'] + +This allows to use ``mylib`` in the ``USE_LIBS`` of another library or +executable. + +When referring to a ``Library`` name building both types of libraries in +``USE_LIBS``, the shared library is chosen to be linked. But sometimes, +it is wanted to link the static version, in which case the ``Library`` name +needs to be prefixed with ``static:`` in ``USE_LIBS`` + +:: + + a/moz.build: + Library('mylib') + FORCE_SHARED_LIB = True + FORCE_STATIC_LIB = True + STATIC_LIBRARY_NAME = 'mylib_s' + b/moz.build: + Program('myprog') + USE_LIBS += [ + 'static:mylib', + ] + + +Miscellaneous +============= + +The ``SONAME`` variable declares a "shared object name" for the library. It +defaults to the ``Library`` name or the ``SHARED_LIBRARY_NAME`` if set. When +linking to a library with a ``SONAME``, the resulting library or program will +have a dependency on the library with the name corresponding to the ``SONAME`` +instead of the ``Library`` name. This only impacts ELF systems. + +:: + + a/moz.build: + Library('mylib') + b/moz.build: + Library('otherlib') + SONAME = 'foo' + c/moz.build: + Program('myprog') + USE_LIBS += [ + 'mylib', + 'otherlib', + ] + +On e.g. Linux, the above ``myprog`` will have DT_NEEDED markers for +``libmylib.so`` and ``libfoo.so`` instead of ``libmylib.so`` and +``libotherlib.so`` if there weren't a ``SONAME``. This means the runtime +requirement for ``myprog`` is ``libfoo.so`` instead of ``libotherlib.so``. + + +Gecko-related binaries +====================== + +Some programs or libraries are totally independent of Gecko, and can use the +above mentioned templates. Others are Gecko-related in some way, and may +need XPCOM linkage, mozglue. These things are tedious. A set of additional +templates exists to ease defining such programs and libraries. They are +essentially the same as the above mentioned templates, prefixed with "Gecko": + + - ``GeckoProgram`` + - ``GeckoSimplePrograms`` + - ``GeckoCppUnitTests`` + - ``GeckoSharedLibrary`` + - ``GeckoFramework`` + +All the Gecko-prefixed templates take the same arguments as their +non-Gecko-prefixed counterparts, and can take a few more arguments +for non-standard cases. See the definition of ``GeckoBinary`` in +build/gecko_templates.mozbuild for more details, but most usecases +should not require these additional arguments. diff --git a/build/docs/defining-xpcom-components.rst b/build/docs/defining-xpcom-components.rst new file mode 100644 index 0000000000..8e4f66c9c0 --- /dev/null +++ b/build/docs/defining-xpcom-components.rst @@ -0,0 +1,318 @@ +.. _defining_xpcom_components: + +========================= +Defining XPCOM Components +========================= + +This document explains how to write a :code:`components.conf` file.

Say we have 2 ``moz.build`` files:: + + # /moz.build + with Files('*.cpp'): + BUG_COMPONENT = ('Core', 'XPCOM') + + with Files('**/*.js'): + BUG_COMPONENT = ('Firefox', 'General') + + # /foo/moz.build + with Files('*.js'): + BUG_COMPONENT = ('Another', 'Component') + +Querying for metadata for the file ``/foo/test.js`` will reveal 3 +relevant ``Files`` sub-contexts. They are evaluated as follows: + +1. ``/moz.build - Files('*.cpp')``. Does ``/*.cpp`` match + ``/foo/test.js``? **No**. Ignore this context. +2. ``/moz.build - Files('**/*.js')``. Does ``/**/*.js`` match + ``/foo/test.js``? **Yes**. Apply ``BUG_COMPONENT = ('Firefox', 'General')`` + to us. +3. ``/foo/moz.build - Files('*.js')``. Does ``/foo/*.js`` match + ``/foo/test.js``? **Yes**. Apply + ``BUG_COMPONENT = ('Another', 'Component')``. + +At the end of execution, we have +``BUG_COMPONENT = ('Another', 'Component')`` as the metadata for +``/foo/test.js``. + +One way to look at file metadata is as a stack of data structures. +Each ``Files`` sub-context relevant to a given file is applied on top +of the previous state, starting from an empty state. The final state +wins. + +.. _mozbuild_files_metadata_finalizing: + +Finalizing Values +================= + +The default behavior of ``Files`` sub-context evaluation is to apply new +values on top of old. In most circumstances, this results in desired +behavior. However, there are circumstances where this may not be +desired. There is thus a mechanism to *finalize* or *freeze* values. + +Finalizing values is useful for scenarios where you want to prevent +wildcard matches from overwriting previously-set values. This is useful +for one-off files. + +Let's take ``Makefile.in`` files as an example. The build system module +policy dictates that ``Makefile.in`` files are part of the ``Build +Config`` module and should be reviewed by peers of that module. However, +there exist ``Makefile.in`` files in many directories in the source +tree. Without finalization, a ``*`` or ``**`` wildcard matching rule +would match ``Makefile.in`` files and overwrite their metadata. + +Finalizing of values is performed by setting the ``FINAL`` variable +on ``Files`` sub-contexts. See the +:ref:`Files documentation <mozbuild_subcontext_Files>` for more. + +Here is an example with ``Makefile.in`` files, showing how it is +possible to finalize the ``BUG_COMPONENT`` value.:: + + # /moz.build + with Files('**/Makefile.in'): + BUG_COMPONENT = ('Firefox Build System', 'General') + FINAL = True + + # /foo/moz.build + with Files('**'): + BUG_COMPONENT = ('Another', 'Component') + +If we query for metadata of ``/foo/Makefile.in``, both ``Files`` +sub-contexts match the file pattern. However, since ``BUG_COMPONENT`` is +marked as finalized by ``/moz.build``, the assignment from +``/foo/moz.build`` is ignored. The final value for ``BUG_COMPONENT`` +is ``('Firefox Build System', 'General')``. + +Here is another example:: + + with Files('*.cpp'): + BUG_COMPONENT = ('One-Off', 'For C++') + FINAL = True + + with Files('**'): + BUG_COMPONENT = ('Regular', 'Component') + +For every files except ``foo.cpp``, the bug component will be resolved +as ``Regular :: Component``. However, ``foo.cpp`` has its value of +``One-Off :: For C++`` preserved because it is finalized. + +.. important:: + + ``FINAL`` only applied to variables defined in a context. + + If you want to mark one variable as finalized but want to leave + another mutable, you'll need to use 2 ``Files`` contexts. + +Guidelines for Defining Metadata +================================ + +In general, values defined towards the root of the source tree are +generic and become more specific towards the leaves. For example, +the ``BUG_COMPONENT`` for ``/browser`` might be ``Firefox :: General`` +whereas ``/browser/components/preferences`` would list +``Firefox :: Preferences``. diff --git a/build/docs/glossary.rst b/build/docs/glossary.rst new file mode 100644 index 0000000000..d610f07443 --- /dev/null +++ b/build/docs/glossary.rst @@ -0,0 +1,47 @@ +Build Glossary +============== + +.. glossary:: + :sorted: + + object directory + A directory holding the output of the build system.

The three main entry points above all trigger +related build flows: + +#. Get the localization repository, if needed +#. Run l10n-merge with a prior clobber of the merge dir +#. Copy l10n files to ``dist``, with minor differences here between ``l10n-%`` and ``chrome-%`` +#. Repackage and package + +Details on l10n-merge are described in its own section below. +The copying of files is mainly controlled by ``jar.mn``, in the few source +directories that include localizable files. ``l10n-%`` is used for repacks, +``chrome-%`` for multi-locale packages. The repackaging is dedicated +Python code in ``toolkit/mozapps/installer/l10n-repack.py``, using an existing +package. It strips existing ``chrome`` l10n resources, and adds localizations +and metadata. + +Language packs don't require repackaging. The windows installers are generated +by merely packaging an existing repackaged zip into to an installer. + +Exposing strings +================ + +The localization flow handles a few file formats in well-known locations in the +source tree. + +Alongside being built by including the directory in ``$MOZ_BUILD_APP/locales/Makefile.in`` +and respective entries in a ``jar.mn``, we also have configuration files tailored +to localization tools and infrastructure. They're also controlling which +files l10n-merge handles, and how. + +These configurations are TOML files. They're part of the bigger +localization ecosystem at Mozilla, and `the documentation about the +file format <http://moz-l10n-config.readthedocs.io/en/latest/fileformat.html>`_ +explains how to set them up, and what the entries mean. In short, you find + +.. code-block:: toml + + [paths] + reference = browser/locales/en-US/** + l10n = {l}browser/** + +to add a directory for all localizations. Changes to these files are best +submitted for review by :Pike or :flod. + +These configuration files are the future, and right now, we still have +support for the previous way to configuring l10n, which is described below. + +The locations are commonly in directories like + + :file:`browser/`\ ``locales/en-US/``\ :file:`subdir/file.ext` + +The first thing to note is that only files beneath :file:`locales/en-US` are +exposed to localizers. The second thing to note is that only a few directories +are exposed. Which directories are exposed is defined in files called +``l10n.ini``, which are at a +`few places <https://searchfox.org/mozilla-central/search?q=path%3Al10n.ini&redirect=true>`_ +in the source code. + +An example looks like this + +.. code-block:: ini + + [general] + depth = ../.. + + [compare] + dirs = browser + browser/branding/official + + [includes] + toolkit = toolkit/locales/l10n.ini + +This tells the l10n infrastructure three things: + +* resolve the paths against the directory two levels up +* include files in :file:`browser/locales/en-US` and + :file:`browser/branding/official/locales/en-US` +* load more data from :file:`toolkit/locales/l10n.ini` + +For projects like Thunderbird and SeaMonkey in ``comm-central``, additional +data needs to be provided when including an ``l10n.ini`` from a different +repository: + +.. code-block:: ini + + [include_toolkit] + type = hg + mozilla = mozilla-central + repo = https://hg.mozilla.org/ + l10n.ini = toolkit/locales/l10n.ini + +This tells the l10n infrastructure where to find the repository, and where inside +that repository the ``l10n.ini`` file is. This is needed because for local +builds, :file:`mail/locales/l10n.ini` references +:file:`mozilla/toolkit/locales/l10n.ini`, which is where the comm-central +build setup expects toolkit to be. + +Now that the directories exposed to l10n are known, we can talk about the +supported file formats. + +File formats +------------ + +The following file formats are known to the l10n tool chains: + +Fluent + Used in Firefox UI, both declarative and programmatically. +Properties + Used from JavaScript and C++. When used from js, also comes with + plural support (avoid if possible). +ini + Used by the crashreporter and updater, avoid if possible. + +Adding new formats involves changing various different tools, and is strongly +discouraged. + +Exceptions +---------- +Generally, anything that exists in ``en-US`` needs a one-to-one mapping in +all localizations. There are a few cases where that's not wanted, notably +around locale configuration and locale-dependent metadata. + +For optional strings and files, l10n-merge won't add ``en-US`` content if +the localization doesn't have that content. + +For the TOML files, the +`[[filters]] documentation <https://moz-l10n-config.readthedocs.io/en/latest/fileformat.html#filters>`_ +is a good reference. In short, filters match the localized source code, optionally +a ``key``, and an action. An example like + +.. code-block:: toml + + [filters] + path = "{l}calendar/chrome/calendar/calendar-event-dialog.properties" + key = "re:.*Nounclass[1-9].*" + action = "ignore" + +indicates that the matching messages in ``calendar-event-dialog.properties`` are optional. + +For the legacy ini configuration files, there's a Python module +``filter.py`` next to the main ``l10n.ini``, implementing :py:func:`test`, with the following +signature + +.. code-block:: python + + def test(mod, path, entity = None): + if does_not_matter: + return "ignore" + if show_but_do_not_merge: + return "report" + # default behavior, localizer or build need to do something + return "error" + +For any missing file, this function is called with ``mod`` being +the *module*, and ``path`` being the relative path inside +:file:`locales/en-US`. The module is the top-level dir as referenced in +:file:`l10n.ini`. + +For missing strings, the :py:data:`entity` parameter is the key of the string +in the en-US file. + +l10n-merge +========== + +The chrome registry in Gecko doesn't support fallback from a localization to ``en-US`` at runtime. +Thus, the build needs to ensure that the localization as it's built into +the package has all required strings, and that the strings don't contain +errors. To ensure that, we're *merging* the localization and ``en-US`` +at build time, nick-named l10n-merge. + +For Fluent, we're also removing erroneous messages. For many errors in Fluent, +that's cosmetic, but when a localization has different values or attributes +on a message, that's actually important so that the DOM bindings of Fluent +can apply the translation without having to load the ``en-US`` source to +compare against. + +The process can be manually triggered via + +.. code-block:: bash + + $> ./mach build merge-$AB_CD + +It creates another directory in the object dir, :file:`browser/locales/merge-dir/$AB_CD`, in +which the sanitized files are stored. The actual repackaging process only looks +in the merged directory, so the preparation steps of l10n-merge need to ensure +that all files are generated or copied. + +l10n-merge modifies a file if it supports the particular file type, and there +are missing strings which are not filtered out, or if an existing string +shows an error. See the Checks section below for details. If the files are +not modified, l10n-merge copies them over to the respective location in the +merge dir. + +Checks +------ + +As part of the build and other localization tool chains, we run a variety +of source-based checks. Think of them as linters. + +The suite of checks is usually determined by file type, i.e., there's a +suite of checks for Fluent files and one for properties files, etc. + +Localizations +------------- + +Now that we talked in-depth about how to expose content to localizers, +where are the localizations? + +We host a mercurial repository per locale. All of our +localizations can be found on https://hg.mozilla.org/l10n-central/. + +You can search inside our localized files on +`Transvision <https://transvision.mozfr.org/>`_. diff --git a/build/docs/mozbuild-files.rst b/build/docs/mozbuild-files.rst new file mode 100644 index 0000000000..9d69404732 --- /dev/null +++ b/build/docs/mozbuild-files.rst @@ -0,0 +1,176 @@ +.. _mozbuild-files: + +=============== +moz.build Files +=============== + +``moz.build`` files are the mechanism by which tree metadata (notably +the build configuration) is defined. + +Directories in the tree contain ``moz.build`` files which declare +functionality for their respective part of the tree.

However, +they are executed in a special Python *sandbox* that significantly +changes and limits the execution environment. The environment is so +different, it's doubtful most ``moz.build`` files would execute without +error if executed by a vanilla Python interpreter (e.g. ``python +moz.build``. + +The following properties make execution of ``moz.build`` files special: + +1. The execution environment exposes a limited subset of Python. +2. There is a special set of global symbols and an enforced naming + convention of symbols. +3. Some symbols are inherited from previously-executed ``moz.build`` + files. + +The limited subset of Python is actually an extremely limited subset. +Only a few symbols from ``__builtin__`` are exposed. These include +``True``, ``False``, ``None``, ``sorted``, ``int``, and ``set``. Global +functions like ``import``, ``print``, and ``open`` aren't available. +Without these, ``moz.build`` files can do very little. *This is by design*. + +The execution sandbox treats all ``UPPERCASE`` variables specially. Any +``UPPERCASE`` variable must be known to the sandbox before the script +executes. Any attempt to read or write to an unknown ``UPPERCASE`` +variable will result in an exception being raised. Furthermore, the +types of all ``UPPERCASE`` variables is strictly enforced. Attempts to +assign an incompatible type to an ``UPPERCASE`` variable will result in +an exception being raised. + +The strictness of behavior with ``UPPERCASE`` variables is a very +intentional design decision. By ensuring strict behavior, any operation +involving an ``UPPERCASE`` variable is guaranteed to have well-defined +side-effects. Previously, when the build configuration was defined in +``Makefiles``, assignments to variables that did nothing would go +unnoticed. ``moz.build`` files fix this problem by eliminating the +potential for false promises. + +After a ``moz.build`` file has completed execution, only the +``UPPERCASE`` variables are used to retrieve state. + +The set of variables and functions available to the Python sandbox is +defined by the :py:mod:`mozbuild.frontend.context` module. The +data structures in this module are consumed by the +:py:class:`mozbuild.frontend.reader.MozbuildSandbox` class to construct +the sandbox. There are tests to ensure that the set of symbols exposed +to an empty sandbox are all defined in the ``context`` module. +This module also contains documentation for each symbol, so nothing can +sneak into the sandbox without being explicitly defined and documented. + +Reading and Traversing moz.build Files +====================================== + +The process for reading ``moz.build`` files roughly consists of: + +1. Start at the root ``moz.build`` (``<topsrcdir>/moz.build``). +2. Evaluate the ``moz.build`` file in a new sandbox. +3. Emit the main *context* and any *sub-contexts* from the executed + sandbox. +4. Extract a set of ``moz.build`` files to execute next. +5. For each additional ``moz.build`` file, goto #2 and repeat until all + referenced files have executed. + +From the perspective of the consumer, the output of reading is a stream +of :py:class:`mozbuild.frontend.reader.context.Context` instances. Each +``Context`` defines a particular aspect of data. Consumers iterate over +these objects and do something with the data inside. Each object is +essentially a dictionary of all the ``UPPERCASE`` variables populated +during its execution. + +.. note:: + + Historically, there was only one ``context`` per ``moz.build`` file. + As the number of things tracked by ``moz.build`` files grew and more + and more complex processing was desired, it was necessary to split these + contexts into multiple logical parts. It is now common to emit + multiple contexts per ``moz.build`` file. + +Build System Reading Mode +------------------------- + +The traditional mode of evaluation of ``moz.build`` files is what's +called *build system traversal mode.* In this mode, the ``CONFIG`` +variable in each ``moz.build`` sandbox is populated from data coming +from ``config.status``, which is produced by ``configure``. + +During evaluation, ``moz.build`` files often make decisions conditional +on the state of the build configuration. e.g. *only compile foo.cpp if +feature X is enabled*. + +In this mode, traversal of ``moz.build`` files is governed by variables +like ``DIRS`` and ``TEST_DIRS``. For example, to execute a child +directory, ``foo``, you would add ``DIRS += ['foo']`` to a ``moz.build`` +file and ``foo/moz.build`` would be evaluated. + +.. _mozbuild_fs_reading_mode: + +Filesystem Reading Mode +----------------------- + +There is an alternative reading mode that doesn't involve the build +system and doesn't use ``DIRS`` variables to control traversal into +child directories. This mode is called *filesystem reading mode*. + +In this reading mode, the ``CONFIG`` variable is a dummy, mostly empty +object. Accessing all but a few special variables will return an empty +value. This means that nearly all ``if CONFIG['FOO']:`` branches will +not be taken. + +Instead of using content from within the evaluated ``moz.build`` +file to drive traversal into subsequent ``moz.build`` files, the set +of files to evaluate is controlled by the thing doing the reading. + +A single ``moz.build`` file is not guaranteed to be executable in +isolation. Instead, we must evaluate all *parent* ``moz.build`` files +first. For example, in order to evaluate ``/foo/moz.build``, one must +execute ``/moz.build`` and have its state influence the execution of +``/foo/moz.build``. + +Filesystem reading mode is utilized to power the +:ref:`mozbuild_files_metadata` feature. + +Technical Details +----------------- + +The code for reading ``moz.build`` files lives in +:py:mod:`mozbuild.frontend.reader`. The Python sandboxes evaluation results +(:py:class:`mozbuild.frontend.context.Context`) are passed into +:py:mod:`mozbuild.frontend.emitter`, which converts them to classes defined +in :py:mod:`mozbuild.frontend.data`. Each class in this module defines a +domain-specific component of tree metadata. e.g. there will be separate +classes that represent a JavaScript file vs a compiled C++ file or test +manifests. This means downstream consumers of this data can filter on class +types to only consume what they are interested in. + +There is no well-defined mapping between ``moz.build`` file instances +and the number of :py:mod:`mozbuild.frontend.data` classes derived from +each. Depending on the content of the ``moz.build`` file, there may be 1 +object derived or 100. + +The purpose of the ``emitter`` layer between low-level sandbox execution +and metadata representation is to facilitate a unified normalization and +verification step. There are multiple downstream consumers of the +``moz.build``-derived data and many will perform the same actions. This +logic can be complicated, so we have a component dedicated to it. + +:py:class:`mozbuild.frontend.reader.BuildReader`` and +:py:class:`mozbuild.frontend.reader.TreeMetadataEmitter`` have a +stream-based API courtesy of generators. When you hook them up properly, +the :py:mod:`mozbuild.frontend.data` classes are emitted before all +``moz.build`` files have been read. This means that downstream errors +are raised soon after sandbox execution. + +Lots of the code for evaluating Python sandboxes is applicable to +non-Mozilla systems. In theory, it could be extracted into a standalone +and generic package. However, until there is a need, there will +likely be some tightly coupled bits. diff --git a/build/docs/mozbuild-symbols.rst b/build/docs/mozbuild-symbols.rst new file mode 100644 index 0000000000..4e9a8853a0 --- /dev/null +++ b/build/docs/mozbuild-symbols.rst @@ -0,0 +1,7 @@ +.. _mozbuild_symbols: + +======================== +mozbuild Sandbox Symbols +======================== + +.. mozbuildsymbols:: mozbuild.frontend.context diff --git a/build/docs/mozbuild/index.rst b/build/docs/mozbuild/index.rst new file mode 100644 index 0000000000..1dbb368034 --- /dev/null +++ b/build/docs/mozbuild/index.rst @@ -0,0 +1,40 @@ +======== +mozbuild +======== + +mozbuild is a Python package providing functionality used by Mozilla's +build system. + +Modules Overview +================ + +* mozbuild.backend -- Functionality for producing and interacting with build + backends.

So all you should need is a vanilla Python install and you +should be good to go. + +Only CPython (the Python distribution available from www.python.org) is +supported. + +Compiled Python Packages +======================== + +There are some features of the build that rely on compiled Python packages +(packages containing C source). These features are currently all +optional because not every system contains the Python development +headers required to build these extensions. + +We recommend you have the Python development headers installed (``mach +bootstrap`` should do this for you) so you can take advantage of these +features. + +Issues with OS X System Python +============================== + +The Python that ships with OS X has historically been littered with +subtle bugs and suboptimalities. + +OS X 10.8 and below users will be required to install a new Python +distribution. This may not be necessary for OS X 10.9+. However, we +still recommend installing a separate Python because of the history with +OS X's system Python issues. + +We recommend installing Python through Homebrew or MacPorts.

Venv provides +standalone and isolated Python "virtual environments". The problem a venv +solves is that of dependencies across multiple Python components. If two +components on a system relied on different versions of a package, there +could be a conflict. Instead of managing multiple versions of a package +simultaneously, Python and venv take the route that it is easier +to just keep them separate so there is no potential for conflicts. + +Very early in the build process, a venv is created inside the +:term:`object directory`. The venv is configured such that it can +find all the Python packages in the source tree. The code for this lives +in ``mach.site``. + +Deficiencies +------------ + +There are numerous deficiencies with the way virtual environments are +handled in the build system. + +* mach reinvents the venv. + + There is code in ``build/mach_initialize.py`` that configures ``sys.path`` + much the same way the venv does. There are various bugs tracking + this. However, no clear solution has yet been devised. It's not a huge + problem and thus not a huge priority. + +* They aren't preserved across copies and packaging. + + If you attempt to copy an entire tree from one machine to another or + from one directory to another, chances are the venv will fall + apart.

Instead of + actually solving portable venv, all we really need to solve is + encapsulating the logic for populating the venv along with all + dependent files in the appropriate place. + +* .pyc files written to source directory. + + We rely heavily on ``.pth`` files in our venv. A ``.pth`` file + is a special file that contains a list of paths. Python will take the + set of listed paths encountered in ``.pth`` files and add them to + ``sys.path``. + + When Python compiles a ``.py`` file to bytecode, it writes out a + ``.pyc`` file so it doesn't have to perform this compilation again. + It puts these ``.pyc`` files alongside the ``.pyc`` file. Python + provides very little control for determining where these ``.pyc`` files + go, even in Python 3 (which offers customer importers). + + With ``.pth`` files pointing back to directories in the source tree + and not the object directory, ``.pyc`` files are created in the source + tree. This is bad because when Python imports a module, it first looks + for a ``.pyc`` file before the ``.py`` file. If there is a ``.pyc`` + file but no ``.py`` file, it will happily import the module. This + wreaks havoc during file moves, refactoring, etc. + + There are various proposals for fixing this. See bug 795995. + +Installing Python Manually +========================== + +We highly recommend you use your system's package manager or a +well-supported 3rd party package manager to install Python for you. If +these are not available to you, we recommend the following tools for +installing Python: + +* `buildout.python <https://github.com/collective/buildout.python>`_ +* `pyenv <https://github.com/yyuu/pyenv>`_ +* An official installer from http://www.python.org. + +If all else fails, consider compiling Python from source manually. But this +should be viewed as the least desirable option. + +Common Issues with Python +========================= + +Upgrading your Python distribution breaks the venv +-------------------------------------------------------- + +If you upgrade the Python distribution (e.g. install Python 3.6.15 +from 3.6.9), chances are parts of the venv will break. +This commonly manifests as a cryptic ``Cannot import XXX`` exception. +More often than not, the module being imported contains binary/compiled +components. + +If you upgrade or reinstall your Python distribution, we recommend +clobbering your build. + +Packages installed at the system level conflict with build system's +------------------------------------------------------------------- + +It is common for people to install Python packages using ``sudo`` (e.g. +``sudo pip install psutil``) or with the system's package manager +(e.g. ``apt-get install python-mysql``. + +A problem with this is that packages installed at the system level may +conflict with the package provided by the source tree. As of bug 907902 +and changeset f18eae7c3b27 (September 16, 2013), this should no longer +be an issue since the venv created as part of the build doesn't +add the system's ``site-packages`` directory to ``sys.path``. However, +poorly installed packages may still find a way to creep into the mix and +interfere with our venv. + +As a general principle, we recommend against using your system's package +manager or using ``sudo`` to install Python packages. Instead, create +virtual environments and isolated Python environments for all of your +Python projects. + +Python on $PATH is not appropriate +---------------------------------- + +Tools like ``mach`` will look for Python by performing ``/usr/bin/env +python`` or equivalent. Please be sure the appropriate Python 2.7.3+ +path is on $PATH.

Building a static library that is linked into a dynamic +library is easier than building dynamic libraries directly, and it also avoids +some subtle issues around how mozalloc works that make the Rust dynamic library +path a little wonky. + +Linking Rust crates into something else +======================================= + +To link Rust code into libraries other than libxul, create a directory with a +``Cargo.toml`` file for your crate, and a ``moz.build`` file that contains: + +.. code-block:: python + + RustLibrary('crate_name') + +where ``crate_name`` matches the name from the ``[package]`` section of your +``Cargo.toml``. You can refer to `the moz.build file <https://searchfox.org/mozilla-central/rev/603b9fded7a11ff213c0f415198cd637b7c86614/toolkit/library/rust/moz.build#9>`_ and `the Cargo.toml file <https://searchfox.org/mozilla-central/rev/603b9fded7a11ff213c0f415198cd637b7c86614/toolkit/library/rust/Cargo.toml>`_ that are used for libxul. + +You can then add ``USE_LIBS += ['crate_name']`` to the ``moz.build`` file +that defines the binary as you would with any other library in the tree. + +.. important:: + + You cannot link a Rust crate into an intermediate library that will be + eventually linked into libxul. The build system enforces that only a single + ``RustLibrary`` may be linked into a binary. If you need to do this, you + will have to add a ``RustLibrary`` to link to any standalone binaries that + link the intermediate library, and also add the Rust crate to the libxul + dependencies as in `linking Rust Crates into libxul`_. + +Conditional compilation +======================== + +Edit `tool/library/rust/gkrust-features.mozbuild +<https://searchfox.org/mozilla-central/source/toolkit/library/rust/gkrust-features.mozbuild>`_ +to expose build flags as Cargo features. + +Standalone Rust programs +======================== + +It is also possible to build standalone Rust programs. First, put the Rust +program (including the ``Cargo.toml`` file and the ``src`` directory) in its +own directory, and add an empty ``moz.build`` file to the same directory. + +Then, if the standalone Rust program must run on the compile target (e.g. +because it's shipped with Firefox) then add this rule to the ``moz.build`` +file: + +.. code-block:: python + + RUST_PROGRAMS = ['prog_name'] + +where *prog_name* is the name of the executable as specified in the +``Cargo.toml`` (and probably also matches the name of the directory). + +Otherwise, if the standalone Rust program must run on the compile host (e.g. +because it's used to build Firefox but not shipped with Firefox) then do the +same thing, but use ``HOST_RUST_PROGRAMS`` instead of ``RUST_PROGRAMS``. + +Where should I put my crate? +============================ + +If your crate's canonical home is mozilla-central, you can put it next to the +related code in the appropriate directory. + +If your crate is mirrored into mozilla-central from another repository, and +will not be actively developed in mozilla-central, you can simply list it +as a ``crates.io``-style dependency with a version number, and let it be +vendored into the ``third_party/rust`` directory. + +If your crate is mirrored into mozilla-central from another repository, but +will be actively developed in both locations, you should send mail to the +dev-builds mailing list to start a discussion on how to meet your needs. + +Third-party crate dependencies +============================== + +Third-party dependencies for in-tree Rust crates are *vendored* into the +``third_party/rust`` directory of mozilla-central. This means that a copy of +each third-party crate's code is committed into mozilla-central. As a result, +building Firefox does not involve downloading any third-party crates. + +If you add a dependency on a new crate you must run ``mach vendor rust`` to +vendor the dependencies into that directory. (Note that ``mach vendor rust`` +`may not work as well on Windows <https://bugzilla.mozilla.org/show_bug.cgi?id=1647582>`_ +as on other platforms.) + +When it comes to checking the suitability of third-party code for inclusion +into mozilla-central, keep the following in mind. + +- ``mach vendor rust`` will check that the licenses of all crates are suitable. +- ``mach vendor rust`` will run ``cargo vet`` to ensure that the crates have been audited. If not, + you will have to audit them using ``mach cargo vet`` to check that the code looks reasonable + (especially unsafe code) and that there are reasonable tests. All vendored crates must be audited. +- Third-party crate tests aren't run, which means that large test fixtures will + bloat mozilla-central. Consider working with upstream to mark those test + fixtures with ``[package] exclude = ...`` as described + `here <https://doc.rust-lang.org/cargo/reference/manifest.html#the-exclude-and-include-fields>`_. +- If you specify a dependency on a branch, pin it to a specific revision, + otherwise other people will get unexpected changes when they run ``./mach + vendor rust`` any time the branch gets updated. See `bug 1612619 + <https://bugzil.la/1612619>`_ for a case where such a problem was fixed. +- Other than that, there is no formal sign-off procedure, but one may be added + in the future. + +Note that all dependencies will be vendored, even ones that aren't used due to +disabled features. It's possible that multiple versions of a crate will end up +vendored into mozilla-central. + +Patching third-party crates +=========================== + +Sometimes you might want to temporarily patch a third-party crate, for local +builds or for a try push. + +To do this, first add an entry to the ``[patch.crates-io]`` section of the +top-level ``Cargo.toml`` that points to the crate within ``third_party``. For +example + +.. code-block:: toml + + bitflags = { path = "third_party/rust/bitflags" } + +Next, run ``cargo update -p $CRATE_NAME --precise $VERSION``, where +``$CRATE_NAME`` is the name of the patched crate, and ``$VERSION`` is its +version number. This will update the ``Cargo.lock`` file. + +Then, make the local changes to the crate. + +Finally, make sure you don't accidentally land the changes to the crate or the +``Cargo.lock`` file. + +For an example of a more complex workflow involving a third-party crate, see +`mp4parse-rust/README.md <https://searchfox.org/mozilla-central/source/media/mp4parse-rust/README.md>`_. +It describes the workflow for a crate that is hosted on GitHub, and for which +changes are made via GitHub pull requests, but all pull requests must also be +tested within mozilla-central before being merged. diff --git a/build/docs/sccache-dist.rst b/build/docs/sccache-dist.rst new file mode 100644 index 0000000000..edd9ead909 --- /dev/null +++ b/build/docs/sccache-dist.rst @@ -0,0 +1,199 @@ +.. _sccache_dist: + +================================== +Distributed sccache (sccache-dist) +================================== + +`sccache <https://github.com/mozilla/sccache>`_ is a ccache-like tool written in +Rust by Mozilla and many contributors. + +sccache-dist, its distributed variant, elevates this functionality by enabling +the distribution and caching of Rust compilations across multiple machines. +Please consider using sccache-dist when you have several machines +compiling Firefox on the same network. + +The steps for setting up your machine as an sccache-dist server are detailed below. + +In addition to improved security properties, distributed sccache offers +distribution and caching of rust compilation, so it should be an improvement +above and beyond what we see with icecc.

There are +many reasons contributing to its slowness. +However, on modern hardware, Firefox can be built in less than 10 minutes. + +First, it is important to distinguish between a :term:`clobber build` +and an :term:`incremental build`. The reasons for why each are slow can +be different. + +The build does a lot of work +============================ + +It may not be obvious, but the main reason the build system is slow is +because it does a lot of work! The source tree consists of a few +thousand C++ files. On a modern machine, we spend over 120 minutes of CPU +core time compiling files! So, if you are looking for the root cause of +slow clobber builds, look at the sheer volume of C++ files in the tree. + +You don't have enough CPU cores and MHz +======================================= + +The build should be CPU bound. If the build system maintainers are +optimizing the build system perfectly, every CPU core in your machine +should be 100% saturated during a build. While this isn't currently the +case (keep reading below), generally speaking, the more CPU cores you +have in your machine and the more total MHz in your machine, the better. + +**We highly recommend building with no fewer than 4 physical CPU +cores.** Please note the *physical* in this sentence. Hyperthreaded +cores (an Intel Core i7 will report 8 CPU cores but only 4 are physical +for example) only yield at most a 1.25x speedup per core. + +This cause impacts both clobber and incremental builds. + +You are building with a slow I/O layer +====================================== + +The build system can be I/O bound if your I/O layer is slow. Linking +libxul on some platforms and build architectures can perform gigabytes +of I/O. + +To minimize the impact of slow I/O on build performance, **we highly +recommend building with an SSD.** Power users with enough memory may opt +to build from a RAM disk. Mechanical disks should be avoided if at all +possible. + +Some may dispute the importance of an SSD on build times. It is true +that the beneficial impact of an SSD can be mitigated if your system has +lots of memory and the build files stay in the page cache. However, +operating system memory management is complicated. You don't really have +control over what or when something is evicted from the page cache. +Therefore, unless your machine is a dedicated build machine or you have +more memory than is needed by everything running on your machine, +chances are you'll run into page cache eviction and you I/O layer will +impact build performance. That being said, an SSD certainly doesn't +hurt build times. And, anyone who has used a machine with an SSD will +tell you how great of an investment it is for performance all around the +operating system. On top of that, some automated tests are I/O bound +(like those touching SQLite databases), so an SSD will make tests +faster. + +This cause impacts both clobber and incremental builds. + +You don't have enough memory +============================ + +The build system allocates a lot of memory, especially when building +many things in parallel. If you don't have enough free system memory, +the build will cause swap activity, slowing down your system and the +build. Even if you never get to the point of swapping, the build system +performs a lot of I/O and having all accessed files in memory and the +page cache can significantly reduce the influence of the I/O layer on +the build system. + +**We recommend building with no less than 8 GB of system memory.** As +always, the more memory you have, the better. For a bare bones machine +doing nothing more than building the source tree, anything more than 16 +GB is likely entering the point of diminishing returns. + +This cause impacts both clobber and incremental builds. + +You are building on Windows +=========================== + +New processes on Windows are about a magnitude slower to spawn than on +UNIX-y systems such as Linux. This is because Windows has optimized new +threads while the \*NIX platforms typically optimize new processes. +Anyway, the build system spawns thousands of new processes during a +build. Parts of the build that rely on rapid spawning of new processes +are slow on Windows as a result. This is most pronounced when running +*configure*. The configure file is a giant shell script and shell +scripts rely heavily on new processes. This is why configure +can run over a minute slower on Windows. + +Another reason Windows builds are slower is because Windows lacks proper +symlink support. On systems that support symlinks, we can generate a +file into a staging area then symlink it into the final directory very +quickly. On Windows, we have to perform a full file copy. This incurs +much more I/O. And if done poorly, can muck with file modification +times, messing up build dependencies. + +These issues impact both clobber and incremental builds. + +make is inefficient +=================== + +Compared to modern build backends like Tup or Ninja, `make` is slow and +inefficient. We can only make `make` so fast. At some point, we'll hit a +performance plateau and will need to use a different tool to make builds +faster. + +Please note that clobber and incremental builds are different. A clobber build +with `make` will likely be as fast as a clobber build with a modern build +system. + +C++ header dependency hell +========================== + +Modifying a *.h* file can have significant impact on the build system. +If you modify a *.h* that is used by 1000 C++ files, all of those 1000 +C++ files will be recompiled. + +Our code base has traditionally been sloppy managing the impact of +changed headers on build performance. Bug 785103 tracks improving the +situation. + +This issue mostly impacts the times of an :term:`incremental build`. + +A search/indexing service on your machine is running +==================================================== + +Many operating systems have a background service that automatically +indexes filesystem content to make searching faster. On Windows, you +have the Windows Search Service. On OS X, you have Finder. + +These background services sometimes take a keen interest in the files +being produced as part of the build. Since the build system produces +hundreds of megabytes or even a few gigabytes of file data, you can +imagine how much work this is to index! If this work is being performed +while the build is running, your build will be slower. + +OS X's Finder is notorious for indexing when the build is running. And, +it has a tendency to suck up a whole CPU core. This can make builds +several minutes slower. If you build with ``mach`` and have the optional +``psutil`` package built (it requires Python development headers - see +:ref:`python` for more) and Finder is running during a build, mach will +print a warning at the end of the build, complete with instructions on +how to fix it. diff --git a/build/docs/snap.rst b/build/docs/snap.rst new file mode 100644 index 0000000000..6ff52da4e8 --- /dev/null +++ b/build/docs/snap.rst @@ -0,0 +1,132 @@ +.. _snap: + +====================== +Firefox Snap Packaging +====================== + +This page explains interactions between Firefox and Snap packaging format. + +Where is the upstream +===================== + +The code reference itself is mozilla-central, but the packaging is being worked +within the `Canonical's firefox-snap repository <https://github.com/canonical/firefox-snap/>`_. + +This packaging includes a few more bits and dependencies, including compiler. +It will also re-download the mercurial repository: this is on purpose. + +Where to report bugs +==================== + +All bugs should be reported to Bugzilla's ``Third Party Packaging`` component, +and marked as blocking ``snap`` meta-bug. + +Build process +============= + +While there is an existing ``repackage`` `task +<https://searchfox.org/mozilla-central/source/taskcluster/docker/firefox-snap>`_, +is currently is no up-to-date and it is not usable from ``mach`` (work is being +`tracked in <https://bugzilla.mozilla.org/show_bug.cgi?id=1841370>`_ for this), +so unfortunately the only way to work right now is a full rebuild using +upstream tooling. + +The following steps should be enough, assuming you have properly setup: + + - ``snapcraft`` (see `quickstart doc <https://snapcraft.io/docs/snapcraft-quickstart>`_) + - ``LXD`` (see `providers doc <https://snapcraft.io/docs/build-providers>`_) + +While the documentation still refers to `Multipass`, the Firefox Snap and its +dependency had some requirements that made it better suited to use `LXD`. + +When performing the checkout, please keep in mind the branch mapping: + + - `edge` is our `nightly` + - `beta` is our `beta` + - `stable` is our `release` + - `esr` is our `esr` + +.. code-block:: shell + + $ git clone https://github.com/canonical/firefox-snap --branch BRANCH + $ snap run snapcraft + +You should end up after some time with two files: ``firefox-XXX.snap`` and +``firefox-XXX.debug``.

These are called *sparse profiles*. + +Essentially, the sparse profiles are managed just like any other file in +the repository. When you ``hg update``, the sparse configuration is +evaluated against the sparse profile at the revision being updated to. +From an end-user perspective, you just need to *activate* a profile once +and files will be added or removed as appropriate whenever the versioned +profile file updates. + +In the Firefox repository, the ``build/sparse-profiles`` directory +contains Mercurial *sparse profiles* files. + +Each *sparse profile* essentially defines a list of file patterns +(see ``hg help patterns``) to include or exclude.

But if a sparse checkout +is being used, ``mach`` assumes that file isn't part of the sparse +checkout and to ignore missing file errors. This means that +running ``mach`` inside a sparse checkout will only have access +to the commands defined in files in the sparse checkout. + +Sparse Checkouts in Automation +============================== + +``hg robustcheckout`` (the extension/command used to perform clones +and working directory operations in automation) supports sparse checkout. +However, it has a number of limitations over Mercurial's default sparse +checkout implementation: + +* Only supports 1 profile at a time +* Does not support non-profile sparse configs +* Does not allow transitioning from a non-sparse to sparse checkout or + vice-versa + +These restrictions ensure that any sparse working directory populated by +``hg robustcheckout`` is as consistent and robust as possible. + +``run-task`` (the low-level script for *bootstrapping* tasks in +automation) has support for sparse checkouts. + +TaskGraph tasks using ``run-task`` can specify a ``sparse-profile`` +attribute in YAML (or in code) to denote the sparse profile file to +use. e.g.:: + + run: + using: run-command + command: <command> + sparse-profile: taskgraph + +This automagically results in ``run-task`` and ``hg robustcheckout`` +using the sparse profile defined in ``build/sparse-profiles/<value>``. + +Pros and Cons of Sparse Checkouts +================================= + +The benefits of sparse checkout are that it makes the repository appear +to be smaller. This means: + +* Less time performing working directory operations -> faster version + control operations +* Fewer files to consult -> faster operations +* Working directories only contain what is needed -> easier to understand + what everything does + +Fewer files in the working directory also contributes to disadvantages: + +* Searching may not yield hits because a file isn't in the sparse + checkout. e.g. a *global* search and replace may not actually be + *global* after all. +* Tools performing filesystem walking or path globbing (e.g. + ``**/*.js``) may fail to find files because they don't exist. +* Various tools and processes make assumptions that all files in the + repository are always available. + +There can also be problems caused by mixing sparse and non-sparse +checkouts. For example, if a process in automation is using sparse +and a local developer is not using sparse, things may work for the +local developer but fail in automation (because a file isn't included +in the sparse configuration and not available to automation. +Furthermore, if environments aren't using exactly the same sparse +configuration, differences can contribute to varying behavior. + +When Should Sparse Checkouts Be Used? +===================================== + +Developers are discouraged from using sparse checkouts for local work +until tools for handling sparse checkouts have improved. In particular, +Mercurial's support for sparse is still experimental and various Firefox +tools make assumptions that all files are available. Developers should +use sparse checkout at their own risk. + +The use of sparse checkouts in automation is a performance versus +robustness trade-off. Use of sparse checkouts will make automation +faster because machines will only have to manage a few thousand files +in a checkout instead of a few hundred thousand. This can potentially +translate to minutes saved per machine day. At the scale of thousands +of machines, the savings can be significant. But adopting sparse +checkouts will open up new avenues for failures. (See section above.) +If a process is isolated (in terms of file access) and well-understood, +sparse checkout can likely be leveraged with little risk.

(Used in + xpcshell tests.) + +tail + List of files that will be executed after the test file. (Used in + xpcshell tests.) + +support-files + List of additional files required to run tests. This is typically + defined in the **DEFAULT** section. + + Unlike other file lists, *support-files* supports a globbing mechanism + to facilitate pulling in many files with minimal typing. This globbing + mechanism is activated if an entry in this value contains a ``*`` + character. A single ``*`` will wildcard match all files in a directory. + A double ``**`` will descend into child directories. For example, + ``data/*`` will match ``data/foo`` but not ``data/subdir/bar`` where + ``data/**`` will match ``data/foo`` and ``data/subdir/bar``. + + Support files starting with ``/`` are placed in a root directory, rather + than a location determined by the manifest location. For mochitests, + this allows for the placement of files at the server root.

In + this case, a test depending on a support file from another directory + must note that dependency with the path to the required support file + in its own **support-files** entry. These use a syntax where paths + starting with ``!/`` will indicate the beginning of the path to a + shared support file starting from the root of the srcdir. For example, + if a manifest at ``dom/base/test/mochitest.toml`` has a support file, + ``dom/base/test/server-script.sjs``, and a mochitest in + ``dom/workers/test`` depends on that support file, the test manifest + at ``dom/workers/test/mochitest.toml`` must include + ``!/dom/base/test/server-script.sjs`` in its **support-files** entry. + +generated-files + List of files that are generated as part of the build and don't exist in + the source tree. + + The build system assumes that each manifest file, test file, and file + listed in **head**, **tail**, and **support-files** is static and + provided by the source tree (and not automatically generated as part + of the build).

It is also +recommended to upgrade the worker-type to e.g. ``b-linux-large``. + +Rust's build dependencies are fairly minimal, and it has a sanity check +that should catch any missing or too-old dependencies. See the `Rust README`_ +for more details. + +Patches are set via `the --patch flag`_ (passed via ``toolchain/rust.yml``). +Patch paths are assumed to be relative to ``/build/build-rust/``, and may be +optionally prefixed with ``module-path:`` to specify they apply to that git +submodule in the Rust source. e.g. ``--patch src/llvm-project:mypatch.diff`` +patches rust's llvm with ``/build/build-rust/mypatch.diff``. There are no +currently checked in rust patches to use as an example, but they should be +the same format as `the clang ones`_. + +Rust builds are not currently configurable, and uses a `hardcoded config.toml`_, +which you may need to edit for your purposes. See Rust's `example config`_ for +details/defaults. Note that these options do occasionally change, so be sure +you're using options for the version you're targeting. For instance, there was +a large change around Rust ~1.48, and the currently checked in config was for +1.47, so it may not work properly when building the latest version of Rust. + +Rust builds are currently limited to targeting only the host platform. +Although the machinery is in place to request additional targets, the +cross-compilation fails for some unknown reason. We have not yet investigated +what needs to be done to get this working. + +While Rust generally maintains a clean tree for building ``rustc`` and +``cargo``, other tools like ``rustfmt`` or ``miri`` are allowed to be +transiently broken. This means not every commit in the Rust tree will be +able to build the `tools we require`_. + +Although ``repack_rust`` considers ``rustfmt`` an optional package, Rust builds +do not currently implement this and will fail if ``rustfmt`` is busted. Some +attempt was made to work around it, but `more work is needed`_. + +.. _Rust's ci: https://github.com/rust-lang/rust/pull/77875#issuecomment-736092083 +.. _repack_rust.py: https://searchfox.org/mozilla-central/source/taskcluster/scripts/misc/repack_rust.py +.. _fetch of the rust tree: https://searchfox.org/mozilla-central/rev/168c45a7acc44e9904cfd4eebcb9eb080e05699c/taskcluster/ci/toolchain/rust.yml#69-71 +.. _clang and binutils toolchains: https://searchfox.org/mozilla-central/rev/168c45a7acc44e9904cfd4eebcb9eb080e05699c/taskcluster/ci/toolchain/rust.yml#72-74 +.. _the --patch flag: https://searchfox.org/mozilla-central/rev/168c45a7acc44e9904cfd4eebcb9eb080e05699c/taskcluster/scripts/misc/repack_rust.py#667-675 +.. _the clang ones: https://searchfox.org/mozilla-central/rev/168c45a7acc44e9904cfd4eebcb9eb080e05699c/build/build-clang/static-llvm-symbolizer.patch +.. _Rust README: https://github.com/rust-lang/rust/#building-on-a-unix-like-system +.. _hardcoded config.toml: https://searchfox.org/mozilla-central/rev/168c45a7acc44e9904cfd4eebcb9eb080e05699c/taskcluster/scripts/misc/repack_rust.py#384-421 +.. _example config: https://github.com/rust-lang/rust/blob/b7ebc6b0c1ba3c27ebb17c0b496ece778ef11e18/config.toml.example +.. _tools we require: https://searchfox.org/mozilla-central/rev/168c45a7acc44e9904cfd4eebcb9eb080e05699c/taskcluster/scripts/misc/repack_rust.py#398 +.. _more work is needed: https://github.com/rust-lang/rust/issues/79249 + +Python +------ + +Python is built from source by ``taskcluster/scripts/misc/build-cpython.sh`` on +Linux and OSX.

The build automation will download, +verify, and extract these archive before building. These archives +provide a self-contained Gradle and Maven repository so that machines +don't need to fetch additional Maven dependencies at build time. +(Gradle and the downloaded Maven dependencies can be both +redistributed publicly.) + +Archiving the Gradle executable is straight-forward, but archiving a +local Maven repository is not. Therefore a toolchain job exists for +producing the required archives, `android-gradle-dependencies`. The +job runs in a container based on a custom Docker image and spawns a +Sonatype Nexus proxying Maven repository process in the background. +The job builds Firefox for Android using Gradle and the in-tree Gradle +configuration rooted at ``build.gradle``. The spawned proxying Maven +repository downloads external dependencies and collects them. After +the Gradle build completes, the job archives the Gradle version used +to build, and the downloaded Maven repository, and exposes them as +Task Cluster artifacts. + +To update the version of Gradle in the archive produced, update +``gradle/wrapper/gradle-wrapper.properties``. Be sure to also update +the SHA256 checksum to prevent poisoning the build machines! + +To update the versions of Gradle dependencies used, update +``dependencies`` sections in the in-tree Gradle configuration rooted +at ``build.gradle``. Once you are confident your changes build +locally, push a fresh build to try. The `android-gradle-dependencies` +toolchain should run automatically, fetching your new dependencies and +wiring them into the appropriate try build jobs. + +To update the version of Sonatype Nexus, update the `sonatype-nexus` +`fetch` task definition. + +To modify the Sonatype Nexus configuration, typically to proxy a new +remote Maven repository, modify +`taskcluster/scripts/misc/android-gradle-dependencies/nexus.xml`. + +There is also a toolchain job that fetches the Android SDK and related +packages. To update the versions of packaged fetched, modify +`python/mozboot/mozboot/android-packages.txt` and update the various +in-tree versions accordingly. diff --git a/build/docs/unified-builds.rst b/build/docs/unified-builds.rst new file mode 100644 index 0000000000..b0e93b9e68 --- /dev/null +++ b/build/docs/unified-builds.rst @@ -0,0 +1,55 @@ +.. _unified-builds: + +============== +Unified Builds +============== + +The Firefox build system uses the technique of "unified builds" (or elsewhere +called "`unity builds <https://en.wikipedia.org/wiki/Unity_build>`_") to +improve compilation performance.

There's a limit on the number of files that are combined +together for a single compilation, so sometimes the addition of a new file will cause another one +to be bumped into a different chunk. If that other chunk doesn't meet the implicit requirements +of the bumped file, there will be a tough-to-debug compilation failure. + +Building outside of the unified environment +=========================================== + +As described above, unified builds can cause source files to implicitly depend on each other, which +not only causes unexpected build failures but also can cause issues when using source-analysis tools. +To combat this, we'll use a "non-unified" build that attempts to perform a build with as many files compiled +individually as possible. + +To build in the non unified mode, set the following flag in your ``mozconfig``: + +``ac_add_options --disable-unified-build`` + +Other notes: +============ + +* Some IDEs (such as VSCode with ``clangd``) build files in standalone mode, so they may show + more failures than a ``mach build``. +* The amount of files per chunk can be adjusted in ``moz.build`` files with the + ``FILES_PER_UNIFIED_FILE`` variable.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES.

Most people find it easier to +read lower case letters than all capitals, but for some applications +(for example, where keys must be scanned optically by hardware that +only recognises capital letters), capitals are required. Selecting +“Mixed case” creates keys with a mix of upper- and +lower-case letters; such keys are more secure than those with uniform +letter case, but do not pass the “telephone test”: you +can't read them across a (hopefully secure) voice link without having +to indicate whether each letter is or is not a capital. +</p> + +<h4><a name="RandomSep">Random separators</a></h4> + +<p> +When the <a href="#KeyLength">Key length</a> is longer than +a nonzero <a href="#GroupLength">Group length</a> specification, +the key is divided into sequences of the given group length +by separator characters. By default, a hyphen, “<tt>-</tt>”, is used +to separate groups. If you check this box, separators will be +chosen at random among punctuation marks generally acceptable +for applications such as passwords. If you're generating passwords +for a computer system, random separators dramatically increase +the difficulty of guessing passwords by exhaustive search. +</p> + +<h4><a name="Signatures">Include signatures</a></h4> + +<p> + +When this box is checked, at the end of the list of keys, preceded by +a line beginning with ten dashes “<tt>-</tt>”, the 128 bit MD5 signature of +each key is given, one per line, with signatures expressed as 32 +hexadecimal digits. Key signatures can be used to increase security +when keys are used to control access to computer systems or databases. +Instead of storing a copy of the keys, the computer stores their +signatures. When the user enters a key, its signature is computed +with the same MD5 algorithm used to generate it initially, and the key +is accepted only if the signature matches. Since discovering +a key which will generate a given signature is believed to be +computationally prohibitive, even if the list of signatures stored on +the computer is compromised, that information will not permit an +intruder to deduce a valid key. +</p> + +<p> +Signature calculation is a computationally intense process for which +JavaScript is not ideally suited; be patient while signatures are +generated, especially if your computer has modest +processing speed. +</p> + +<p> +For signature-based validation to be secure, it is essential +the original keys be long enough to prohibit discovery of matching +signatures by exhaustive search. Suppose, for example, one used +four digit numeric keys, as used for Personal Identification +Numbers (PINs) by many credit card systems. Since only 10,000 +different keys exist, one could simply compute the signatures of +every possible key from 0000 through 9999, permitting an attacker who +came into possession of the table of signatures to recover the +keys by a simple lookup process. For maximum security, keys must +contain at least as much information as the 128 bit signatures +computed from them. This implies a minimum key length (not counting +non-random separator characters) for the various key formats as +follows: +</p> + +<table class="c" border="border" cellpadding="4"> +<tr><th>Key Composition</th> <th>Minimum Characters</th></tr> + +<tr><td>Numeric</td> <td class="c">39</td></tr> +<tr><td>Word-like</td> <td class="c">30</td></tr> +<tr><td>Alphabetic</td> <td class="c">28</td></tr> +<tr><td>Gibberish</td> <td class="c">20</td></tr> +</table> + +<p> +It should be noted that for many practical applications there is no +need for anything approaching 128-bit security. The guidelines above +apply only in the case where maximum protection in the event of +undetected compromise of key signatures occurs. In many +cases, much shorter keys are acceptable, especially when it is assumed +that a compromise of the system's password or signature database would +be only part of a much more serious subversion of all resources +on the system. +</p> + +<h3><a name="Seed">Seed</a></h3> + +<p> +The <em>seed</em> is the starting value which determines all +subsequent values in the pseudorandom sequence used to generate +the one-time pad. Given the seed, the pad can be reproduced. The +seed is a 31-bit number which can be derived from the date and +time at which the one-time pad was requested, or from a +user-defined seed value. If the user-defined seed consists +entirely of decimal digits, it is used directly as the seed, +modulo 2<sup>31</sup>; if a string containing non-digit characters +is entered, it is used to compute a <em>hash code</em> which is +used to seed the generator. + +</p> + +<p> +When the clock is used to create the seed, the seed value is entered +in the User-defined box to allow you, by checking “User-defined”, +to produce additional pads with the same seed. +</p> + +<h2><a name="why">Why JavaScript?</a></h2> + +<p> +At first glance, JavaScript may seem an odd choice for programming +a page such as this. The one-time pad generator program is rather +large and complicated, and downloading it to your browser takes longer +than would be required for a Java applet or to transfer a +one-time pad generated by a CGI program on the Web server. I chose +JavaScript for two reasons: <em>security</em> and <em>transparency</em>. + +</p> + +<p> +<b>Security.</b> +The sole reason for the existence of one-time pads is to +provide a source of information known only to people to whom +they have been distributed in a secure manner. This means +the generation process cannot involve any link whose security +is suspect. If the pad were generated on a Web server and +transmitted to you, it would have to pass over the +Internet, where any intermediate site might make a copy +of your pad before you even received it. Even if some +mechanism such as encryption could absolutely prevent the +pad's being intercepted, you'd still have no way to be sure +the site generating the pad didn't keep a copy +in a file, conveniently tagged with your Internet address. +</p> + +<p> +In order to have any degree of security, it is essential +that the pad be generated on <em>your</em> computer, without +involving any transmission or interaction with other +sites on the Internet. A Web browser with JavaScript makes +this possible, since the generation program embedded in this +page runs entirely on your own computer and does not +transmit anything over the Internet. Its output appears +only in the text box, allowing you to cut and paste it +to another application. From there on, its security is +up to you. +</p> + +<p> +Security is never absolute. A one-time pad generated with +this page might be compromised in a variety of ways, including +the following: + +</p> + +<ul> +<li> Your Web browser and/or JavaScript interpreter may + contain bugs or deliberate security violations + which report activity on your computer back to some + other Internet site.</li> + +<li> Some other applet running on another page of your + browser, perhaps without your being aware of its + existence, is spying on other windows.</li> + +<li> Some other application running on your computer + may have compromised your system's security and + be snooping on your activity.</li> + +<li> Your Web browser may be keeping a “history log” + + or “cache” of data you generate. Somebody may + come along later and recover a copy of the pad + from that log.</li> + +<li> The implementation of this page may contain a bug + or deliberate error which makes its output + predictable. This is why <a href="#trans"><cite>transparency</cite></a>, + discussed below, is essential.</li> + +<li> Your computer's security may have been compromised + physically; when's the last time you checked that a + bug that transmits your keystrokes and/or screen + contents to that white van parked down the street + wasn't lurking inside your computer cabinet?</li> +</ul> + +<p> +One can whip oneself into a fine fever of paranoia worrying about +things like this. One way to rule out the most probable risks +is to download a copy of the generator page and run it +from a “<tt>file:</tt>” URL on a computer which has no network +connection whatsoever and is located in a secure location +under your control. And look very carefully at any files +created by your Web browser. You may find the most interesting +things squirreled away there…. +</p> + +<p> +<b><a name="trans">Transparency</a>.</b> +Any security-related tool is only as good as its design +and implementation. <em>Transparency</em> means that, in +essence, all the moving parts are visible so you can judge +for yourself whether the tool merits your confidence. In +the case of a program, this means that source code must +be available, and that you can verify that the program +you're running corresponds to the source code provided. + +</p> + +<p> +The very nature of JavaScript achieves this transparency. +The program is embedded into this actual Web page; to +examine it you need only use your browser's “View Source” +facility, or save the page into a file on your computer +and read it with a text editor. JavaScript's being +an interpreted language eliminates the risk of your running +a program different from the purported source code: with +an interpreted language what you read is what you run. +</p> + +<p> +Transparency is important even if you don't know enough about +programming or security to determine whether the program +contains any flaws. The very fact that it can be examined +by anybody allows those with the required expertise to pass +judgment, and you can form your own conclusions based on +their analysis. +</p> + +<h2>Credits</h2> + +<p> + +The pseudorandom sequence generator is based on L'Ecuyer's +two-sequence generator as described in +<cite>Communications of the ACM</cite>, Vol. 31 (1968), page 742. +A Bays-Durham shuffle is used to guard against regularities +lurking in L'Ecuyer's algorithm; see +<cite>ACM Transactions on Mathematical Software</cite>, Vol. 2 (1976) +pages 59–64 for details. +</p> + +<p> +The JavaScript implementation of the +<a href="http://www.ietf.org/rfc/rfc1321.txt"><b>MD5 message-digest algorithm</b></a> +was developed by Henri Torgemane; please view the source code of this +page to examine the code, including the copyright notice and +conditions of use.
