+// Refcounted objects should implement the following informal interface:
+//
+// void AddRef() const ;
+// RefCountReleaseStatus Release() const;
+//
+// You may access members of a reference-counted object, including the AddRef()
+// and Release() methods, only if you already own a reference to it, or if
+// you're borrowing someone else's reference. (A newly created object is a
+// special case: the reference count is zero on construction, and the code that
+// creates the object should immediately call AddRef(), bringing the reference
+// count from zero to one, e.g., by constructing an rtc::scoped_refptr).
+//
+// AddRef() creates a new reference to the object.
+//
+// Release() releases a reference to the object; the caller now has one less
+// reference than before the call. Returns kDroppedLastRef if the number of
+// references dropped to zero because of this (in which case the object destroys
+// itself). Otherwise, returns kOtherRefsRemained, to signal that at the precise
+// time the caller's reference was dropped, other references still remained (but
+// if other threads own references, this may of course have changed by the time
+// Release() returns).
+//
+// The caller of Release() must treat it in the same way as a delete operation:
+// Regardless of the return value from Release(), the caller mustn't access the
+// object. The object might still be alive, due to references held by other
+// users of the object, but the object can go away at any time, e.g., as the
+// result of another thread calling Release().

-Upstream commit: https://webrtc.googlesource.com/src/+/91d5fc2ed6ef347d90182868320267d45cf9525b
-    Support more pixel formats in v4l2 camera backend
-
-    These were tested with gstreamer and v4l2loopback, example setup:
-    $ sudo v4l2loopback-ctl add -n BGRA 10
-    $ gst-launch-1.0 videotestsrc pattern=smpte-rp-219 ! \
-      video/x-raw,format=BGRA ! v4l2sink device=/dev/video10 > /dev/null &
-
-    Then conversion was confirmed with video_loopback:
-    $ ./video_loopback --capture_device_index=3 --logs 2>&1 | grep -i \
-      capture
-

+Subject: Bug 1838080: Store the rid in TransformableVideoSenderFrame.
+ r=ng,webrtc-reviewers
 
-There are situations where the current thread is not set, but the current
-TaskQueue is (but not vice versa).
+This is necessary to reliably detect what rid a given keyframe is for, for the
+purposes of resolving promises from RTCRtpScriptTransformer.generateKeyFrame.

++"""Produces localized strings.xml files for Android.
++
++In cases where an "android" type output file is requested in a grd, the classes
++in android_xml will process the messages and translations to produce a valid
++strings.xml that is properly localized with the specified language.
++
++For example if the following output tag were to be included in a grd file
++  <outputs>
++    ...
++    <output filename="values-es/strings.xml" type="android" lang="es" />
++    ...
++  </outputs>
++
++for a grd file with the following messages:
++
++  <message name="IDS_HELLO" desc="Simple greeting">Hello</message>
++  <message name="IDS_WORLD" desc="The world">world</message>
++
++and there existed an appropriate xtb file containing the Spanish translations,
++then the output would be:
++
++  <?xml version="1.0" encoding="utf-8"?>
++  <resources xmlns:android="http://schemas.android.com/apk/res/android">
++    <string name="hello">"Hola"</string>
++    <string name="world">"mundo"</string>
++  </resources>
++
++which would be written to values-es/strings.xml and usable by the Android
++resource framework.
++
++Advanced usage
++--------------
++
++To process only certain messages in a grd file, tag each desired message by
++adding "android_java" to formatter_data. Then set the environmental variable
++ANDROID_JAVA_TAGGED_ONLY to "true" when building the grd file. For example:
++
++  <message name="IDS_HELLO" formatter_data="android_java">Hello</message>
++
++To generate Android plurals (aka "quantity strings"), use the ICU plural syntax
++in the grd file. This will automatically be transformed into a <purals> element
++in the output xml file. For example:
++
++  <message name="IDS_CATS">
++    {NUM_CATS, plural,
++    =1 {1 cat}
++    other {# cats}}
++  </message>
++
++  will produce
++
++  <plurals name="cats">
++    <item quantity="one">1 Katze</item>
++    <item quantity="other">%d Katzen</item>
++  </plurals>

++This dictionary defines the language charset pair lookup table, which is used
++for replacing the GRIT expand variables for language info in Product Version
++resource. The key is the language ISO country code, and the value
++is the language and character-set pair, which is a hexadecimal string
++consisting of the concatenation of the language and character-set identifiers.
++The first 4 digit of the value is the hex value of LCID, the remaining
++4 digits is the hex value of character-set id(code page)of the language.
++
++LCID resource: http://msdn.microsoft.com/en-us/library/ms776294.aspx
++Codepage resource: http://www.science.co.il/language/locale-codes.asp
++
++We have defined three GRIT expand_variables to be used in the version resource
++file to set the language info. Here is an example how they should be used in

++"""Prepares a Chrome HTML file by inlining resources and adding references to
++high DPI resources and removing references to unsupported scale factors.
++
++This is a small gatherer that takes a HTML file, looks for src attributes
++and inlines the specified file, producing one HTML file with no external
++dependencies. It recursively inlines the included files. When inlining CSS
++image files this script also checks for the existence of high DPI versions
++of the inlined file including those on relevant platforms. Unsupported scale
++factors are also removed from existing image sets to support explicitly
++referencing all available images.

++'''A gatherer for the TotalRecall brand of HTML templates with replaceable
++portions.  We wanted to reuse extern.tclib.api.handlers.html.TCHTMLParser
++but this proved impossible due to the fact that the TotalRecall HTML templates
++are in general quite far from parseable HTML and the TCHTMLParser derives
++
++from HTMLParser.HTMLParser which requires relatively well-formed HTML.  Some
++examples of "HTML" from the TotalRecall HTML templates that wouldn't be
++parseable include things like:
++
++  <a [PARAMS]>blabla</a>  (not parseable because attributes are invalid)
++
++  <table><tr><td>[LOTSOFSTUFF]</tr></table> (not parseable because closing
++                                            </td> is in the HTML [LOTSOFSTUFF]
++                                            is replaced by)
++
++The other problem with using general parsers (such as TCHTMLParser) is that
++we want to make sure we output the TotalRecall template with as little changes
++as possible in terms of whitespace characters, layout etc.  With any parser
++that generates a parse tree, and generates output by dumping the parse tree,
++we would always have little inconsistencies which could cause bugs (the
++TotalRecall template stuff is quite brittle and can break if e.g. a tab
++character is replaced with spaces).
++
++The solution, which may be applicable to some other HTML-like template
++languages floating around Google, is to create a parser with a simple state
++machine that keeps track of what kind of tag it's inside, and whether it's in
++a translateable section or not.  Translateable sections are:
++
++a) text (including [BINGO] replaceables) inside of tags that
++   can contain translateable text (which is all tags except
++   for a few)
++
++b) text inside of an 'alt' attribute in an <image> element, or
++   the 'value' attribute of a <submit>, <button> or <text>
++   element.
++
++The parser does not build up a parse tree but rather a "skeleton" which
++is a list of nontranslateable strings intermingled with grit.clique.MessageClique
++objects.  This simplifies the parser considerably compared to a regular HTML
++parser.  To output a translated document, each item in the skeleton is
++printed out, with the relevant Translation from each MessageCliques being used
++for the requested language.
++
++This implementation borrows some code, constants and ideas from
++extern.tclib.api.handlers.html.TCHTMLParser.

++'''Pseudotranslation support.  Our pseudotranslations are based on the

++  - "because" becomes "bepecaupause" (but in our implementation we don't
++    handle the silent e at the end so it actually would return "bepecaupausepe"
++
++The P-language has the excellent quality of increasing the length of text
++by around 30-50% which is great for pseudotranslations, to stress test any
++GUI layouts etc.
++
++To make the pseudotranslations more obviously "not a translation" and to make
++them exercise any code that deals with encodings, we also transform all English
++vowels into equivalent vowels with diacriticals on them (rings, acutes,
++diaresis, and circumflex), and we write the "p" in the P-language as a Hebrew

++IBM Lotus Notes Plug-In
++------------------------
++The Lotus Notes plug-in is included in the release of Google 
++Desktop for Enterprise. The IBM Lotus Notes Plug-in for Google 
++Desktop indexes mail, calendar, task, contact and journal 
++documents from Notes.  Discussion documents including those from 
++the discussion and team room templates can also be indexed by 
++selecting an option from the preferences.  Once indexed, this data
++will be returned in Google Desktop searches.  The corresponding
++document can be opened in Lotus Notes from the Google Desktop 
++results page.
++
++Install: The plug-in will install automatically during the Google 
++Desktop setup process if Lotus Notes is already installed.  Lotus 
++Notes must not be running in order for the install to occur.  The
++Class ID for this plug-in is {8F42BDFB-33E8-427B-AFDC-A04E046D3F07}.
++
++Preferences: Preferences and selection of databases to index are
++set in the 'Google Desktop for Notes' dialog reached through the 
++'Actions' menu.
++
++Reindexing: Selecting 'Reindex all databases' will index all the 
++documents in each database again.
++
++
++Notes Plug-in Known Issues
++---------------------------
++
++If the 'Google Desktop for Notes' item is not available from the 
++Lotus Notes Actions menu, then installation was not successful. 
++Installation consists of writing one file, notesgdsplugin.dll, to 
++the Notes application directory and a setting to the notes.ini 
++configuration file.  The most likely cause of an unsuccessful 
++installation is that the installer was not able to locate the 
++notes.ini file. Installation will complete if the user closes Notes
++and manually adds the following setting to this file on a new line:
++AddinMenus=notesgdsplugin.dll
++
++If the notesgdsplugin.dll file is not in the application directory
++(e.g., C:\Program Files\Lotus\Notes) after Google Desktop 
++installation, it is likely that Notes was not installed correctly. 
++
++Only local databases can be indexed.  If they can be determined, 
++the user's local mail file and address book will be included in the
++list automatically.  Mail archives and other databases must be 
++added with the 'Add' button.
++
++Some users may experience performance issues during the initial 
++indexing of a database.  The 'Perform the initial index of a 
++database only when I'm idle' option will limit the indexing process
++to times when the user is not using the machine. If this does not 
++alleviate the problem or the user would like to continually index 
++but just do so more slowly or quickly, the GoogleWaitTime notes.ini
++value can be set. Increasing the GoogleWaitTime value will slow 
++down the indexing process, and lowering the value will speed it up.
++A value of zero causes the fastest possible indexing.  Removing the
++ini parameter altogether returns it to the default (20).
++
++Crashes have been known to occur with certain types of history 
++bookmarks.  If the Notes client seems to crash randomly, try 
++disabling the 'Index note history' option.  If it crashes before,
++you can get to the preferences, add the following line to your 
++notes.ini file:
++GDSNoIndexHistory=1

Pour ce faire, importez le certificat racine de l'entreprise en tant que &quot;certificat racine&quot;. Par la suite, les certificats émis ou vérifiés par votre entreprise seront approuvés et vous ne verrez plus cette erreur lorsque vous tenterez de vous connecter à nouveau au site Web interne.

++<p>
++So that you can easily search your computer, the Google Desktop Search application indexes
++and stores versions of your files and other computer activity, 
++such as email, chats, and web history.  These versions may also be mixed 
++with your Web search results to produce 
++results pages for you that integrate relevant content from your computer and 
++information from the Web.

++Your computer's content is not made accessible to Google or anyone else without your explicit permission.

++class Android2Grd(interface.Tool):
++  """Tool for converting Android string.xml files into chrome Grd files.
++
++Usage: grit [global options] android2grd [OPTIONS] STRINGS_XML
++
++The Android2Grd tool will convert an Android strings.xml file (whose path is
++specified by STRINGS_XML) and create a chrome style grd file containing the
++relevant information.
++
++Because grd documents are much richer than strings.xml documents we supplement
++the information required by grds using OPTIONS with sensible defaults.
++
++OPTIONS may be any of the following:
++
++    --name       FILENAME    Specify the base FILENAME. This should be without
++                             any file type suffix. By default
++                             "chrome_android_strings" will be used.
++

++class RcBuilder(interface.Tool):
++  '''A tool that builds RC files and resource header files for compilation.
++
++Usage:  grit build [-o OUTPUTDIR] [-D NAME[=VAL]]*
++
++All output options for this tool are specified in the input file (see
++'grit help' for details on how to specify the input file - it is a global
++option).
++
++Options:
++
++  -a FILE           Assert that the given file is an output. There can be
++                    multiple "-a" flags listed for multiple outputs. If a "-a"
++                    or "--assert-file-list" argument is present, then the list
++                    of asserted files must match the output files or the tool
++                    will fail. The use-case is for the build system to maintain
++                    separate lists of output files and to catch errors if the
++                    build system's list and the grit list are out-of-sync.
++
++  --assert-file-list  Provide a file listing multiple asserted output files.
++                    There is one file name per line. This acts like specifying
++                    each file with "-a" on the command line, but without the
++                    possibility of running into OS line-length limits for very
++                    long lists.
++
++  -o OUTPUTDIR      Specify what directory output paths are relative to.
++                    Defaults to the current directory.
++
++  -p FILE           Specify a file containing a pre-determined mapping from
++                    resource names to resource ids which will be used to assign
++                    resource ids to those resources. Resources not found in this
++                    file will be assigned ids normally. The motivation is to run
++                    your app's startup and have it dump the resources it loads,
++                    and then pass these via this flag. This will pack startup
++                    resources together, thus reducing paging while all other
++                    resources are unperturbed. The file should have the format:
++                      RESOURCE_ONE_NAME 123
++                      RESOURCE_TWO_NAME 124
++
++  -D NAME[=VAL]     Specify a C-preprocessor-like define NAME with optional
++                    value VAL (defaults to 1) which will be used to control
++                    conditional inclusion of resources.
++
++  -E NAME=VALUE     Set environment variable NAME to VALUE (within grit).
++
++  -f FIRSTIDSFILE   Path to a python file that specifies the first id of
++                    value to use for resources.  A non-empty value here will
++                    override the value specified in the <grit> node's
++                    first_ids_file.
++
++  -w WHITELISTFILE  Path to a file containing the string names of the
++                    resources to include.  Anything not listed is dropped.
++
++  -t PLATFORM       Specifies the platform the build is targeting; defaults
++                    to the value of sys.platform. The value provided via this
++                    flag should match what sys.platform would report for your
++                    target platform; see grit.node.base.EvaluateCondition.
++
++  --whitelist-support
++                    Generate code to support extracting a resource whitelist
++                    from executables.
++
++  --write-only-new flag
++                    If flag is non-0, write output files to a temporary file
++                    first, and copy it to the real output only if the new file
++                    is different from the old file.  This allows some build
++                    systems to realize that dependent build steps might be
++                    unnecessary, at the cost of comparing the output data at
++                    grit time.
++
++  --depend-on-stamp
++                    If specified along with --depfile and --depdir, the depfile
++                    generated will depend on a stampfile instead of the first
++                    output in the input .grd file.
++
++  --js-minifier     A command to run the Javascript minifier. If not set then
++                    Javascript won't be minified. The command should read the
++                    original Javascript from standard input, and output the
++                    minified Javascript to standard output. A non-zero exit
++                    status will be taken as indicating failure.
++
++  --css-minifier    A command to run the CSS minifier. If not set then CSS won't
++                    be minified. The command should read the original CSS from
++                    standard input, and output the minified CSS to standard
++                    output. A non-zero exit status will be taken as indicating
++                    failure.
++
++  --brotli          The full path to the brotli executable generated by
++                    third_party/brotli/BUILD.gn, required if any entries use
++                    compress="brotli".
++
++Conditional inclusion of resources only affects the output of files which
++control which resources get linked into a binary, e.g. it affects .rc files
++meant for compilation but it does not affect resource header files (that define
++IDs).  This helps ensure that values of IDs stay the same, that all messages
++are exported to translation interchange files (e.g. XMB files), etc.

++  '''A tool for converting .rc files to .grd files.  This tool is only for
++converting the source (nontranslated) .rc file to a .grd file.  For importing
++existing translations, use the rc2xtb tool.
++
++Usage:  grit [global options] rc2grd [OPTIONS] RCFILE
++
++The tool takes a single argument, which is the path to the .rc file to convert.
++It outputs a .grd file with the same name in the same directory as the .rc file.
++The .grd file may have one or more TODO comments for things that have to be
++cleaned up manually.
++
++OPTIONS may be any of the following:
++
++  -e ENCODING    Specify the ENCODING of the .rc file. Default is 'cp1252'.
++
++  -h TYPE        Specify the TYPE attribute for HTML structures.
++                 Default is 'tr_html'.
++
++  -u ENCODING    Specify the ENCODING of HTML files. Default is 'utf-8'.
++
++  -n MATCH       Specify the regular expression to match in comments that will
++                 indicate that the resource the comment belongs to is not
++                 translateable. Default is 'Not locali(s|z)able'.
++
++  -r GRDFILE     Specify that GRDFILE should be used as a "role model" for
++                 any placeholders that otherwise would have had TODO names.
++                 This attempts to find an identical message in the GRDFILE
++                 and uses that instead of the automatically placeholderized
++                 message.
++
++  --pre CLASS    Specify an optional, fully qualified classname, which
++                 has to be a subclass of grit.tool.PreProcessor, to
++                 run on the text of the RC file before conversion occurs.
++                 This can be used to support constructs in the RC files
++                 that GRIT cannot handle on its own.
++
++  --post CLASS   Specify an optional, fully qualified classname, which
++                 has to be a subclass of grit.tool.PostProcessor, to
++                 run on the text of the converted RC file.
++                 This can be used to alter the content of the RC file
++                 based on the conversion that occured.
++
++For menus, dialogs and version info, the .grd file will refer to the original
++.rc file.  Once conversion is complete, you can strip the original .rc file
++of its string table and all comments as these will be available in the .grd
++file.
++
++Note that this tool WILL NOT obey C preprocessor rules, so even if something
++is #if 0-ed out it will still be included in the output of this tool
++Therefore, if your .rc file contains sections like this, you should run the
++C preprocessor on the .rc file or manually edit it before using this tool.

++class ResizeDialog(interface.Tool):
++  '''Generates an RC file, header and Visual Studio project that you can use
++with Visual Studio's GUI resource editor to modify the layout of dialogs for
++the language of your choice.  You then use the RC file, after you resize the
++dialog, for the language or languages of your choice, using the <skeleton> child
++of the <structure> node for the dialog.  The translateable bits of the dialog
++will be ignored when you use the <skeleton> node (GRIT will instead use the
++translateable bits from the original dialog) but the layout changes you make
++will be used.  Note that your layout changes must preserve the order of the
++translateable elements in the RC file.
++
++Usage: grit resize [-f BASEFOLDER] [-l LANG] [-e RCENCODING] DIALOGID*
++
++Arguments:
++  DIALOGID        The 'name' attribute of a dialog to output for resizing.  Zero
++                  or more of these parameters can be used.  If none are
++                  specified, all dialogs from the input .grd file are output.
++
++Options:
++
++  -f BASEFOLDER   The project will be created in a subfolder of BASEFOLDER.
++                  The name of the subfolder will be the first DIALOGID you
++                  specify.  Defaults to '.'
++
++  -l LANG         Specifies that the RC file should contain a dialog translated
++                  into the language LANG.  The default is a cp1252-representable
++                  pseudotranslation, because Visual Studio's GUI RC editor only
++                  supports single-byte encodings.
++
++  -c CODEPAGE     Code page number to indicate to the RC compiler the encoding
++                  of the RC file, default is something reasonable for the
++                  language you selected (but this does not work for every single
++                  language).  See details on codepages below.  NOTE that you do
++                  not need to specify the codepage unless the tool complains
++                  that it's not sure which codepage to use.  See the following
++                  page for codepage numbers supported by Windows:
++                  http://www.microsoft.com/globaldev/reference/wincp.mspx
++
++  -D NAME[=VAL]   Specify a C-preprocessor-like define NAME with optional
++                  value VAL (defaults to 1) which will be used to control
++                  conditional inclusion of resources.
++
++
++IMPORTANT NOTE:  For now, the tool outputs a UTF-8 encoded file for any language
++that can not be represented in cp1252 (i.e. anything other than Western
++European languages).  You will need to open this file in a text editor and
++save it using the codepage indicated in the #pragma code_page(XXXX) command
++near the top of the file, before you open it in Visual Studio.

++
++Usage:
++
++grit -i GRD transl2tc [-l LIMITS] [RCOPTS] SOURCE_RC TRANSLATED_RC OUT_FILE
++
++The tool needs a "source" RC file, i.e. in English, and an RC file that is a
++translation of precisely the source RC file (not of an older or newer version).
++
++The tool also requires you to provide a .grd file (input file) e.g. using the
++-i global option or the GRIT_INPUT environment variable.  The tool uses
++information from your .grd file to correct placeholder names in the
++translations and ensure that only translatable items and translations still
++being used are output.
++
++This tool will accept all the same RCOPTS as the 'grit rc2grd' tool.  To get
++a list of these options, run 'grit help rc2grd'.
++
++Additionally, you can use the -l option (which must be the first option to the
++tool) to specify a file containing a list of message IDs to which output should
++be limited.  This is only useful if you are limiting the output to your XMB
++files using the 'grit xmb' tool's -l option.  See 'grit help xmb' for how to
++generate a file containing a list of the message IDs in an XMB file.
++
++The tool will scan through both of the RC files as well as any HTML files they
++refer to, and match together the source messages and translated messages.  It
++will output a file (OUTPUT_FILE) you can import directly into the TC using the
++Bulk Translation Upload tool.

++"""Package grit.tool.update_resource_ids
++
++Updates GRID resource_ids from linked GRD files, while preserving structure.
++
++A resource_ids file is a JSON dict (with Python comments) that maps GRD paths
++to *items*. Item order is ignored by GRIT, but is important since it establishes
++a narrative of item dependency (needs non-overlapping IDs) and mutual exclusion
++(allows ID overlap). Example:
++
++{
++  # The first entry in the file, SRCDIR, is special: It is a relative path from
++  # this file to the base of your checkout.
++  "SRCDIR": "../..",
++
++  # First GRD file. This entry is an "Item".
++  "1.grd": {
++    "messages": [400],  # "Tag".
++  },
++  # Depends on 1.grd, i.e., 500 >= 400 + (# of IDs used in 1.grd).
++  "2a.grd": {
++    "includes": [500],    # "Tag".
++    "structures": [510],  # "Tag" (etc.).
++  },
++  # Depends on 2a.grd.
++  "3a.grd": {
++    "includes": [1000],
++  },
++  # Depends on 2a.grd, but overlaps with 3b.grd due to mutually exclusivity.
++  "3b.grd": {
++    "includes": [1000],
++  },
++  # Depends on {3a.grd, 3b.grd}.
++  "4.grd": {
++    "META": {"join": 2},  # Hint for update_resource_ids.
++    "structures": [1500],
++  },
++  # Depends on 1.grd but overlaps with 2a.grd.
++  "2b.grd": {
++    "includes": [500],
++    "structures": [540],
++  },
++  # Depends on {4.grd, 2b.grd}.
++  "5.grd": {
++    "META": {"join": 2},  # Hint for update_resource_ids.
++    "includes": [600],
++  },
++  # Depends on 5.grd. File is generated, so hint is needed for sizes.
++  "<(SHARED_INTERMEDIATE_DIR)/6.grd": {
++    "META": {"sizes": {"includes": [10]}},
++    "includes": [700],
++  },
++}
++
++The "structure" within a resouces_ids file are as follows:
++1. Comments and spacing.
++2. Item ordering, to establish dependency and grouping.
++3. Special provision to allow ID overlaps from mutual exclusion.
++
++This module parses a resource_ids file, reads ID usages from GRD files it refers
++to, and generates an updated version of the resource_ids file while preserving
++structure elements 1-3 stated above.

++
++Start ID assignment in resource_ids is structured a Series-Parallel Graph, which
++is a directed, acyclic multi-graph generated by the following:
++* Start: Single directed edge. S <-- T.
++* Operation 1: A <-- B becomes A <-- C <-- B.
++* Operation 2: A <-- B becomes A <== B (add parallel edge).
++
++Each vertex (A, B, ...) is a start ID. S = globally minimal ID. T = \infty is an
++implicit sentinel. Each edge maps to an item, and edge weight is ID allotment.
++The edge A <-- B means "A's ID assignment needs to be determined before B's"
++(i.e., "B depends on A"), and requires A < B.
++
++resource_ids stores a "flattened" representation of the graph, as a list of
++items (with meta data). Thus coarse ID assignment consists of the following:
++(1) Process list of items (with old start ID and meta data) to rebuild graph.
++(2) Traverse graph in an order that satisfies dependencies.
++(3) When vertex A has its ID assigned, the weight of each edge "A <--" (i.e., an
++    item) can have its weight (ID allotment) computed via quota assignment of A.
++(4) New start IDs satisfy A + w <= B for each edge A <-- B with weight w > 0.
++
++The key algorithm challenge is (1). Note that it does not need weight details,
++so we only assume A < B whenever A <-- B. Now we're faced with 2 subproblems:
++(1a) How to represent the graph as a list of integers (with meta data)?
++(1b) Given the list representation, how to recover the graph?
++
++For (1a), we start with DFS traversal of the (transposed, i.e., reversed) graph
++starting from S, and apply the following:
++* For each edge A <-- B traversed, emit A into sequence,
++* Traverse a B <-- Y only when all X <-- B have been traversed.
++
++The resulting sequence has the length as the number of edges, and has the useful
++property that a vertex's dependencies always appear before the vertex itself!
++Note this the sentinel T is omitted.
++
++Example 1:
++  S <-- A <-- B <-- C <-- T  => "SABC".
++
++Example 2:
++  S <-- A <-- B <-- C <-- T  => "SA|AB|SDEC|SF",
++  |     |     |     |     |  or "SF|SA|AB|SDEC",
++  |     + <-- +     |     |  or "SDE|SA|ABC|SF",
++  |                 |     |  or "SF|SDE|SA|ABC".
++  + <---D <-- E <---+     |
++  |                       |
++  + <-- F <---------------+
++
++Here, "X|Y" denotes backtracking between visiting X and visiting Y. This appears
++if and only if X >= Y, so "|" an optional (but illustrative) character that's
++not in the actual output. We will use it consistently in comments, and so the
++absence of "|" denotes the converse. For example, "XY" implies X < Y.
++
++In terms of the basic operations:
++* Start: S <-- T => "S".
++* Operation 1: "...AB..." => "...ACB..." (or "...A" => "...AB").
++* Operation 2: "...AB..." => "...A|AB..." (or "...A" => "...A|A").
++
++For Example 2, a viable "evolution path" is:
++"S" => "S|S" => "SC|S" => "S|SC|S" => "SA|SC|S" => "SAB|SC|S" => "SA|AB|SC|S"
++    => "SA|AB|SDC|S" => "SA|AB|SDEC|S" => "SA|AB|SDEC|SF".
++(Alternative: "S|S" => "S|SC" => etc.).
++
++Note: {A, ...} are *unlabelled* integers, and "spurious equalities" such as
++A = D or A = F can occur!
++
++For (1b), we wish to build the graph from the sequence. This requires (1a) to be
++injective (up to isomorphism). Unfortunately, this does not always hold.
++Example:
++  S <-- A <-- C <-- D <-- T  => "SA|SBCD".
++  |           |
++  + <-- B <---+
++vs.
++  S <----- A <----- D <-- T  => "SA|SBCD".
++  |                 |
++  + <-- B <-- C <---+
++
++To fix this, we prepend a "join" label (*) to each vertex that has multiple
++dependencies. With this, the example above produce different results:
++   "SA|SB*CD" != "SA|SBC*D".
++
++Unfortunately, this is also inadequate.  Example:
++  S <-------- B <-- T  => "S|S|S|S*A*B",
++  |           |
++  + <---------+
++  |           |
++  + <-- A <---+
++  |     |
++  + <---+
++vs.
++  S <-------- B <-- T  => "S|S|S|S*A*B".
++  |           |
++  + <---A <---+
++  |     |
++  + <---+
++  |     |
++  + <---+
++
++To fix this, we also label the number of dependencies. In text representation,
++we just show multiple (#dependencies - 1) copies of '*'. Now we have:
++  "S|S|S|S*A**B" != "S|S|S|S**A*B".
++
++The "join" label with count adequately addresses the issue (proof omitted). In
++the resource_ids files, these are stored as the "join" field of an item's meta
++data.
++
++Additional comments for (1b) and other steps are detailed below.

++
++OUTPUTPATH is the path you want to output the .xmb file to.

++The -l option can be used to output only some of the resources to the .xmb file.
++LIMITFILE is the path to a file that is used to limit the items output to the
++xmb file.  If the filename extension is .grd, the file must be a .grd file

++exist in the limit file (as compared on the 'name' attribute). Otherwise it must
++contain a list of the IDs that output should be limited to, one ID per line, and
++the tool will only output nodes with 'name' attributes that match one of the
++IDs.
++
++The -i option causes 'grit xmb' to output an "IDs only" file instead of an XMB
++file.  The "IDs only" file contains the message ID of each message that would
++normally be output to the XMB file, one message ID per line.  It is designed for
++use with the 'grit transl2tc' tool's -l option.

++
++# Instantiate grit. This will produce a script target to run grit (named
++# ${target_name}_grit), and a static library that compiles the .cc files.
++#
++# In general, code should depend on the static library. However, if the
++# generated files are only processed by other actions to generate other
++# files, it is possible to depend on the script target directly.
++#
++# Parameters
++#
++#   source (required)
++#       Path to .grd file.
++#
++#   enable_input_discovery_for_gn_analyze (default=true)
++#       Runs grit_info.py via exec_script() when compute_inputs_for_analyze=true
++#       in order to discover all files that affect this target.
++#       Turn this off when the .grd file is generated, or an <include> with
++#       flattenhtml=true points to a generated file.
++#       For "gn analyze" to be correct with this arg disabled, all inputs
++#       must be listed via |inputs|.
++#
++#   inputs  (optional)
++#       List of additional files, required for grit to process source file.
++#
++#   outputs (required)
++#       List of outputs from grit, relative to the target_gen_dir. Grit will
++#       verify at build time that this list is correct and will fail if there
++#       is a mismatch between the outputs specified by the .grd file and the
++#       outputs list here.
++#
++#       To get this list, you can look in the .grd file for
++#       <output filename="..." and put those filename here. The base directory
++#       of the list in Grit and the output list specified in the GN grit target
++#       are the same (the target_gen_dir) so you can generally copy the names
++#       exactly.
++#
++#       To get the list of outputs programatically, run:
++#           python tools/grit/grit_info.py --outputs . path/to/your.grd
++#       And strip the leading "./" from the output files.
++#
++#   defines (optional)
++#       Extra defines to pass to grit (on top of the global grit_defines list).
++#
++#   grit_flags (optional)
++#       List of strings containing extra command-line flags to pass to Grit.
++#
++#   resource_ids (optional)
++#       Path to a grit "firstidsfile". Default is
++#       //tools/gritsettings/resource_ids. Set to "" to use the value specified
++#       in the <grit> nodes of the processed files.
++#
++#   output_dir (optional)
++#       Directory for generated files. If you specify this, you will often
++#       want to specify output_name if the target name is not particularly
++#       unique, since this can cause files from multiple grit targets to
++#       overwrite each other.
++#
++#   output_name (optional)
++#       Provide an alternate base name for the generated files, like the .d
++#       files. Normally these are based on the target name and go in the
++#       output_dir, but if multiple targets with the same name end up in
++#       the same output_dir, they can collide.
++#
++#   configs (optional)
++#       List of additional configs to be applied to the generated target.
++#
++#   deps  (optional)
++#   testonly (optional)
++#   visibility  (optional)
++#       Normal meaning.
++#
++# Example
++#
++#   grit("my_resources") {
++#     # Source and outputs are required.
++#     source = "myfile.grd"
++#     outputs = [
++#       "foo_strings.h",
++#       "foo_strings.pak",
++#     ]
++#
++#     grit_flags = [ "-E", "foo=bar" ]  # Optional extra flags.
++#     # You can also put deps here if the grit source depends on generated
++#     # files.

++Six is a Python 2 and 3 compatibility library.  It provides utility functions
++for smoothing over the differences between the Python versions with the goal of
++writing Python code that is compatible on both Python versions.  See the
++documentation for more information on what is provided.
++
++Six supports every Python version since 2.6.  It is contained in only one Python
++file, so it can be easily copied into your project. (The copyright and license
++notice must be retained.)
++
++Online documentation is at https://pythonhosted.org/six/.
++
++Bugs can be reported to https://bitbucket.org/gutworth/six.  The code can also
++be found there.
++
++For questions about six or porting in general, email the python-porting mailing
++list: https://mail.python.org/mailman/listinfo/python-porting

-+
-+This is a tool for projects to manage resources and simplify the localization

-+
-+See the user guide for more details on using this project:
-+https://dev.chromium.org/developers/tools-we-use-in-chromium/grit/grit-users-guide
-+
-+## History
-+
-+This code previously used to live at
-+https://code.google.com/p/grit-i18n/source/checkout which still contains the
-+project's history.  https://chromium.googlesource.com/external/grit-i18n/ is
-+a git mirror of the SVN repository that's identical except for the last two
-+commits.  The project is now developed in the Chromium project directly.
-+
-+There is a read-only mirror of just this directory at
-+https://chromium.googlesource.com/chromium/src/tools/grit/ if you don't want to
-+check out all of Chromium.

-+"""Produces localized strings.xml files for Android.
-+
-+In cases where an "android" type output file is requested in a grd, the classes
-+in android_xml will process the messages and translations to produce a valid
-+strings.xml that is properly localized with the specified language.
-+
-+For example if the following output tag were to be included in a grd file
-+  <outputs>
-+    ...
-+    <output filename="values-es/strings.xml" type="android" lang="es" />
-+    ...
-+  </outputs>
-+
-+for a grd file with the following messages:
-+
-+  <message name="IDS_HELLO" desc="Simple greeting">Hello</message>
-+  <message name="IDS_WORLD" desc="The world">world</message>
-+
-+and there existed an appropriate xtb file containing the Spanish translations,
-+then the output would be:
-+
-+  <?xml version="1.0" encoding="utf-8"?>
-+  <resources xmlns:android="http://schemas.android.com/apk/res/android">
-+    <string name="hello">"Hola"</string>
-+    <string name="world">"mundo"</string>
-+  </resources>
-+
-+which would be written to values-es/strings.xml and usable by the Android
-+resource framework.
-+
-+Advanced usage
-+--------------
-+
-+To process only certain messages in a grd file, tag each desired message by
-+adding "android_java" to formatter_data. Then set the environmental variable
-+ANDROID_JAVA_TAGGED_ONLY to "true" when building the grd file. For example:
-+
-+  <message name="IDS_HELLO" formatter_data="android_java">Hello</message>
-+
-+To generate Android plurals (aka "quantity strings"), use the ICU plural syntax
-+in the grd file. This will automatically be transformed into a <purals> element
-+in the output xml file. For example:
-+
-+  <message name="IDS_CATS">
-+    {NUM_CATS, plural,
-+    =1 {1 cat}
-+    other {# cats}}
-+  </message>
-+
-+  will produce
-+

-+'''A gatherer for the TotalRecall brand of HTML templates with replaceable
-+portions.  We wanted to reuse extern.tclib.api.handlers.html.TCHTMLParser
-+but this proved impossible due to the fact that the TotalRecall HTML templates
-+are in general quite far from parseable HTML and the TCHTMLParser derives
-+
-+from HTMLParser.HTMLParser which requires relatively well-formed HTML.  Some
-+examples of "HTML" from the TotalRecall HTML templates that wouldn't be
-+parseable include things like:
-+
-+  <a [PARAMS]>blabla</a>  (not parseable because attributes are invalid)
-+
-+  <table><tr><td>[LOTSOFSTUFF]</tr></table> (not parseable because closing
-+                                            </td> is in the HTML [LOTSOFSTUFF]
-+                                            is replaced by)
-+
-+The other problem with using general parsers (such as TCHTMLParser) is that
-+we want to make sure we output the TotalRecall template with as little changes
-+as possible in terms of whitespace characters, layout etc.  With any parser
-+that generates a parse tree, and generates output by dumping the parse tree,
-+we would always have little inconsistencies which could cause bugs (the
-+TotalRecall template stuff is quite brittle and can break if e.g. a tab
-+character is replaced with spaces).
-+
-+The solution, which may be applicable to some other HTML-like template
-+languages floating around Google, is to create a parser with a simple state
-+machine that keeps track of what kind of tag it's inside, and whether it's in
-+a translateable section or not.  Translateable sections are:
-+
-+a) text (including [BINGO] replaceables) inside of tags that
-+   can contain translateable text (which is all tags except
-+   for a few)
-+
-+b) text inside of an 'alt' attribute in an <image> element, or
-+   the 'value' attribute of a <submit>, <button> or <text>
-+   element.
-+
-+The parser does not build up a parse tree but rather a "skeleton" which
-+is a list of nontranslateable strings intermingled with grit.clique.MessageClique
-+objects.  This simplifies the parser considerably compared to a regular HTML
-+parser.  To output a translated document, each item in the skeleton is
-+printed out, with the relevant Translation from each MessageCliques being used
-+for the requested language.
-+
-+This implementation borrows some code, constants and ideas from
-+extern.tclib.api.handlers.html.TCHTMLParser.

Google Desktop opens a connection for each email folder that it indexes. If insufficient connections are allowed, Google Desktop cannot index all the user email folders.\n\nThe default value is 400.

-+IBM Lotus Notes Plug-In
-+------------------------
-+The Lotus Notes plug-in is included in the release of Google 
-+Desktop for Enterprise. The IBM Lotus Notes Plug-in for Google 
-+Desktop indexes mail, calendar, task, contact and journal 
-+documents from Notes.  Discussion documents including those from 
-+the discussion and team room templates can also be indexed by 
-+selecting an option from the preferences.  Once indexed, this data
-+will be returned in Google Desktop searches.  The corresponding
-+document can be opened in Lotus Notes from the Google Desktop 
-+results page.
-+
-+Install: The plug-in will install automatically during the Google 
-+Desktop setup process if Lotus Notes is already installed.  Lotus 
-+Notes must not be running in order for the install to occur.  The
-+Class ID for this plug-in is {8F42BDFB-33E8-427B-AFDC-A04E046D3F07}.
-+
-+Preferences: Preferences and selection of databases to index are
-+set in the 'Google Desktop for Notes' dialog reached through the 
-+'Actions' menu.
-+
-+Reindexing: Selecting 'Reindex all databases' will index all the 
-+documents in each database again.
-+
-+
-+Notes Plug-in Known Issues
-+---------------------------
-+
-+If the 'Google Desktop for Notes' item is not available from the 
-+Lotus Notes Actions menu, then installation was not successful. 
-+Installation consists of writing one file, notesgdsplugin.dll, to 
-+the Notes application directory and a setting to the notes.ini 
-+configuration file.  The most likely cause of an unsuccessful 
-+installation is that the installer was not able to locate the 
-+notes.ini file. Installation will complete if the user closes Notes
-+and manually adds the following setting to this file on a new line:
-+AddinMenus=notesgdsplugin.dll
-+
-+If the notesgdsplugin.dll file is not in the application directory
-+(e.g., C:\Program Files\Lotus\Notes) after Google Desktop 
-+installation, it is likely that Notes was not installed correctly. 
-+
-+Only local databases can be indexed.  If they can be determined, 
-+the user's local mail file and address book will be included in the
-+list automatically.  Mail archives and other databases must be 
-+added with the 'Add' button.
-+
-+Some users may experience performance issues during the initial 
-+indexing of a database.  The 'Perform the initial index of a 
-+database only when I'm idle' option will limit the indexing process
-+to times when the user is not using the machine. If this does not 
-+alleviate the problem or the user would like to continually index 
-+but just do so more slowly or quickly, the GoogleWaitTime notes.ini
-+value can be set. Increasing the GoogleWaitTime value will slow 
-+down the indexing process, and lowering the value will speed it up.
-+A value of zero causes the fastest possible indexing.  Removing the
-+ini parameter altogether returns it to the default (20).
-+
-+Crashes have been known to occur with certain types of history 
-+bookmarks.  If the Notes client seems to crash randomly, try 
-+disabling the 'Index note history' option.  If it crashes before,
-+you can get to the preferences, add the following line to your 
-+notes.ini file:
-+GDSNoIndexHistory=1

Pour ce faire, importez le certificat racine de l'entreprise en tant que &quot;certificat racine&quot;. Par la suite, les certificats émis ou vérifiés par votre entreprise seront approuvés et vous ne verrez plus cette erreur lorsque vous tenterez de vous connecter à nouveau au site Web interne.

-+  """Tool for converting Android string.xml files into chrome Grd files.
-+
-+Usage: grit [global options] android2grd [OPTIONS] STRINGS_XML
-+
-+The Android2Grd tool will convert an Android strings.xml file (whose path is
-+specified by STRINGS_XML) and create a chrome style grd file containing the
-+relevant information.
-+
-+Because grd documents are much richer than strings.xml documents we supplement
-+the information required by grds using OPTIONS with sensible defaults.
-+
-+OPTIONS may be any of the following:
-+
-+    --name       FILENAME    Specify the base FILENAME. This should be without
-+                             any file type suffix. By default
-+                             "chrome_android_strings" will be used.
-+
-+    --languages  LANGUAGES   Comma separated list of ISO language codes (e.g.
-+                             en-US, en-GB, ru, zh-CN). These codes will be used
-+                             to determine the names of resource and translations
-+                             files that will be declared by the output grd file.
-+
-+    --grd-dir    GRD_DIR     Specify where the resultant grd file
-+                             (FILENAME.grd) should be output. By default this
-+                             will be the present working directory.
-+
-+    --header-dir HEADER_DIR  Specify the location of the directory where grit
-+                             generated C++ headers (whose name will be
-+                             FILENAME.h) will be placed. Use an empty string to
-+                             disable rc generation. Default: empty.
-+
-+    --rc-dir     RC_DIR      Specify the directory where resource files will
-+                             be located relative to grit build's output
-+                             directory. Use an empty string to disable rc
-+                             generation. Default: empty.
-+
-+    --xml-dir    XML_DIR     Specify where to place localized strings.xml files
-+                             relative to grit build's output directory. For each
-+                             language xx a values-xx/strings.xml file will be
-+                             generated. Use an empty string to disable
-+                             strings.xml generation. Default: '.'.
-+
-+    --xtb-dir    XTB_DIR     Specify where the xtb files containing translations
-+                             will be located relative to the grd file. Default:
-+                             '.'.

-+  '''A tool that builds RC files and resource header files for compilation.
-+
-+Usage:  grit build [-o OUTPUTDIR] [-D NAME[=VAL]]*
-+
-+All output options for this tool are specified in the input file (see
-+'grit help' for details on how to specify the input file - it is a global
-+option).
-+
-+Options:
-+
-+  -a FILE           Assert that the given file is an output. There can be
-+                    multiple "-a" flags listed for multiple outputs. If a "-a"
-+                    or "--assert-file-list" argument is present, then the list
-+                    of asserted files must match the output files or the tool
-+                    will fail. The use-case is for the build system to maintain
-+                    separate lists of output files and to catch errors if the
-+                    build system's list and the grit list are out-of-sync.
-+
-+  --assert-file-list  Provide a file listing multiple asserted output files.
-+                    There is one file name per line. This acts like specifying
-+                    each file with "-a" on the command line, but without the
-+                    possibility of running into OS line-length limits for very
-+                    long lists.
-+
-+  -o OUTPUTDIR      Specify what directory output paths are relative to.
-+                    Defaults to the current directory.
-+
-+  -p FILE           Specify a file containing a pre-determined mapping from
-+                    resource names to resource ids which will be used to assign
-+                    resource ids to those resources. Resources not found in this
-+                    file will be assigned ids normally. The motivation is to run
-+                    your app's startup and have it dump the resources it loads,
-+                    and then pass these via this flag. This will pack startup
-+                    resources together, thus reducing paging while all other
-+                    resources are unperturbed. The file should have the format:
-+                      RESOURCE_ONE_NAME 123
-+                      RESOURCE_TWO_NAME 124
-+
-+  -D NAME[=VAL]     Specify a C-preprocessor-like define NAME with optional
-+                    value VAL (defaults to 1) which will be used to control
-+                    conditional inclusion of resources.
-+
-+  -E NAME=VALUE     Set environment variable NAME to VALUE (within grit).
-+
-+  -f FIRSTIDSFILE   Path to a python file that specifies the first id of
-+                    value to use for resources.  A non-empty value here will
-+                    override the value specified in the <grit> node's
-+                    first_ids_file.
-+
-+  -w WHITELISTFILE  Path to a file containing the string names of the
-+                    resources to include.  Anything not listed is dropped.
-+
-+  -t PLATFORM       Specifies the platform the build is targeting; defaults
-+                    to the value of sys.platform. The value provided via this
-+                    flag should match what sys.platform would report for your
-+                    target platform; see grit.node.base.EvaluateCondition.
-+
-+  --whitelist-support
-+                    Generate code to support extracting a resource whitelist
-+                    from executables.
-+
-+  --write-only-new flag
-+                    If flag is non-0, write output files to a temporary file
-+                    first, and copy it to the real output only if the new file
-+                    is different from the old file.  This allows some build
-+                    systems to realize that dependent build steps might be
-+                    unnecessary, at the cost of comparing the output data at
-+                    grit time.
-+
-+  --depend-on-stamp
-+                    If specified along with --depfile and --depdir, the depfile
-+                    generated will depend on a stampfile instead of the first
-+                    output in the input .grd file.
-+
-+  --js-minifier     A command to run the Javascript minifier. If not set then
-+                    Javascript won't be minified. The command should read the
-+                    original Javascript from standard input, and output the
-+                    minified Javascript to standard output. A non-zero exit
-+                    status will be taken as indicating failure.
-+
-+  --css-minifier    A command to run the CSS minifier. If not set then CSS won't
-+                    be minified. The command should read the original CSS from
-+                    standard input, and output the minified CSS to standard
-+                    output. A non-zero exit status will be taken as indicating
-+                    failure.
-+
-+  --brotli          The full path to the brotli executable generated by
-+                    third_party/brotli/BUILD.gn, required if any entries use
-+                    compress="brotli".
-+
-+Conditional inclusion of resources only affects the output of files which
-+control which resources get linked into a binary, e.g. it affects .rc files
-+meant for compilation but it does not affect resource header files (that define
-+IDs).  This helps ensure that values of IDs stay the same, that all messages
-+are exported to translation interchange files (e.g. XMB files), etc.

-+  '''A tool for converting .rc files to .grd files.  This tool is only for
-+converting the source (nontranslated) .rc file to a .grd file.  For importing
-+existing translations, use the rc2xtb tool.
-+
-+Usage:  grit [global options] rc2grd [OPTIONS] RCFILE
-+
-+The tool takes a single argument, which is the path to the .rc file to convert.
-+It outputs a .grd file with the same name in the same directory as the .rc file.
-+The .grd file may have one or more TODO comments for things that have to be
-+cleaned up manually.
-+
-+OPTIONS may be any of the following:
-+
-+  -e ENCODING    Specify the ENCODING of the .rc file. Default is 'cp1252'.
-+
-+  -h TYPE        Specify the TYPE attribute for HTML structures.
-+                 Default is 'tr_html'.
-+
-+  -u ENCODING    Specify the ENCODING of HTML files. Default is 'utf-8'.
-+
-+  -n MATCH       Specify the regular expression to match in comments that will
-+                 indicate that the resource the comment belongs to is not
-+                 translateable. Default is 'Not locali(s|z)able'.
-+
-+  -r GRDFILE     Specify that GRDFILE should be used as a "role model" for
-+                 any placeholders that otherwise would have had TODO names.
-+                 This attempts to find an identical message in the GRDFILE
-+                 and uses that instead of the automatically placeholderized
-+                 message.
-+
-+  --pre CLASS    Specify an optional, fully qualified classname, which
-+                 has to be a subclass of grit.tool.PreProcessor, to
-+                 run on the text of the RC file before conversion occurs.
-+                 This can be used to support constructs in the RC files
-+                 that GRIT cannot handle on its own.
-+
-+  --post CLASS   Specify an optional, fully qualified classname, which
-+                 has to be a subclass of grit.tool.PostProcessor, to
-+                 run on the text of the converted RC file.
-+                 This can be used to alter the content of the RC file
-+                 based on the conversion that occured.
-+
-+For menus, dialogs and version info, the .grd file will refer to the original
-+.rc file.  Once conversion is complete, you can strip the original .rc file
-+of its string table and all comments as these will be available in the .grd
-+file.
-+
-+Note that this tool WILL NOT obey C preprocessor rules, so even if something
-+is #if 0-ed out it will still be included in the output of this tool
-+Therefore, if your .rc file contains sections like this, you should run the
-+C preprocessor on the .rc file or manually edit it before using this tool.

-+the language of your choice.  You then use the RC file, after you resize the
-+dialog, for the language or languages of your choice, using the <skeleton> child
-+of the <structure> node for the dialog.  The translateable bits of the dialog
-+will be ignored when you use the <skeleton> node (GRIT will instead use the
-+translateable bits from the original dialog) but the layout changes you make
-+will be used.  Note that your layout changes must preserve the order of the
-+translateable elements in the RC file.
-+
-+Usage: grit resize [-f BASEFOLDER] [-l LANG] [-e RCENCODING] DIALOGID*
-+
-+Arguments:
-+  DIALOGID        The 'name' attribute of a dialog to output for resizing.  Zero
-+                  or more of these parameters can be used.  If none are
-+                  specified, all dialogs from the input .grd file are output.
-+
-+Options:
-+
-+  -f BASEFOLDER   The project will be created in a subfolder of BASEFOLDER.
-+                  The name of the subfolder will be the first DIALOGID you
-+                  specify.  Defaults to '.'
-+
-+  -l LANG         Specifies that the RC file should contain a dialog translated
-+                  into the language LANG.  The default is a cp1252-representable
-+                  pseudotranslation, because Visual Studio's GUI RC editor only
-+                  supports single-byte encodings.
-+
-+  -c CODEPAGE     Code page number to indicate to the RC compiler the encoding
-+                  of the RC file, default is something reasonable for the
-+                  language you selected (but this does not work for every single
-+                  language).  See details on codepages below.  NOTE that you do
-+                  not need to specify the codepage unless the tool complains
-+                  that it's not sure which codepage to use.  See the following
-+                  page for codepage numbers supported by Windows:
-+                  http://www.microsoft.com/globaldev/reference/wincp.mspx
-+
-+  -D NAME[=VAL]   Specify a C-preprocessor-like define NAME with optional
-+                  value VAL (defaults to 1) which will be used to control
-+                  conditional inclusion of resources.
-+
-+
-+IMPORTANT NOTE:  For now, the tool outputs a UTF-8 encoded file for any language
-+that can not be represented in cp1252 (i.e. anything other than Western
-+European languages).  You will need to open this file in a text editor and
-+save it using the codepage indicated in the #pragma code_page(XXXX) command
-+near the top of the file, before you open it in Visual Studio.

-+
-+Usage:
-+
-+grit -i GRD transl2tc [-l LIMITS] [RCOPTS] SOURCE_RC TRANSLATED_RC OUT_FILE
-+
-+The tool needs a "source" RC file, i.e. in English, and an RC file that is a
-+translation of precisely the source RC file (not of an older or newer version).
-+
-+The tool also requires you to provide a .grd file (input file) e.g. using the
-+-i global option or the GRIT_INPUT environment variable.  The tool uses
-+information from your .grd file to correct placeholder names in the
-+translations and ensure that only translatable items and translations still
-+being used are output.
-+
-+This tool will accept all the same RCOPTS as the 'grit rc2grd' tool.  To get
-+a list of these options, run 'grit help rc2grd'.
-+
-+Additionally, you can use the -l option (which must be the first option to the
-+tool) to specify a file containing a list of message IDs to which output should
-+be limited.  This is only useful if you are limiting the output to your XMB
-+files using the 'grit xmb' tool's -l option.  See 'grit help xmb' for how to
-+generate a file containing a list of the message IDs in an XMB file.
-+
-+The tool will scan through both of the RC files as well as any HTML files they
-+refer to, and match together the source messages and translated messages.  It
-+will output a file (OUTPUT_FILE) you can import directly into the TC using the
-+Bulk Translation Upload tool.

-+
-+Updates GRID resource_ids from linked GRD files, while preserving structure.
-+
-+A resource_ids file is a JSON dict (with Python comments) that maps GRD paths
-+to *items*. Item order is ignored by GRIT, but is important since it establishes
-+a narrative of item dependency (needs non-overlapping IDs) and mutual exclusion
-+(allows ID overlap). Example:
-+
-+{
-+  # The first entry in the file, SRCDIR, is special: It is a relative path from
-+  # this file to the base of your checkout.
-+  "SRCDIR": "../..",
-+
-+  # First GRD file. This entry is an "Item".
-+  "1.grd": {
-+    "messages": [400],  # "Tag".
-+  },
-+  # Depends on 1.grd, i.e., 500 >= 400 + (# of IDs used in 1.grd).
-+  "2a.grd": {
-+    "includes": [500],    # "Tag".
-+    "structures": [510],  # "Tag" (etc.).
-+  },
-+  # Depends on 2a.grd.
-+  "3a.grd": {
-+    "includes": [1000],
-+  },
-+  # Depends on 2a.grd, but overlaps with 3b.grd due to mutually exclusivity.
-+  "3b.grd": {
-+    "includes": [1000],
-+  },
-+  # Depends on {3a.grd, 3b.grd}.
-+  "4.grd": {
-+    "META": {"join": 2},  # Hint for update_resource_ids.
-+    "structures": [1500],
-+  },
-+  # Depends on 1.grd but overlaps with 2a.grd.
-+  "2b.grd": {
-+    "includes": [500],
-+    "structures": [540],
-+  },
-+  # Depends on {4.grd, 2b.grd}.
-+  "5.grd": {
-+    "META": {"join": 2},  # Hint for update_resource_ids.
-+    "includes": [600],
-+  },
-+  # Depends on 5.grd. File is generated, so hint is needed for sizes.
-+  "<(SHARED_INTERMEDIATE_DIR)/6.grd": {
-+    "META": {"sizes": {"includes": [10]}},
-+    "includes": [700],
-+  },
-+}
-+
-+The "structure" within a resouces_ids file are as follows:
-+1. Comments and spacing.
-+2. Item ordering, to establish dependency and grouping.
-+3. Special provision to allow ID overlaps from mutual exclusion.
-+
-+This module parses a resource_ids file, reads ID usages from GRD files it refers
-+to, and generates an updated version of the resource_ids file while preserving
-+structure elements 1-3 stated above.

-+
-+Start ID assignment in resource_ids is structured a Series-Parallel Graph, which
-+is a directed, acyclic multi-graph generated by the following:
-+* Start: Single directed edge. S <-- T.
-+* Operation 1: A <-- B becomes A <-- C <-- B.
-+* Operation 2: A <-- B becomes A <== B (add parallel edge).
-+
-+Each vertex (A, B, ...) is a start ID. S = globally minimal ID. T = \infty is an
-+implicit sentinel. Each edge maps to an item, and edge weight is ID allotment.
-+The edge A <-- B means "A's ID assignment needs to be determined before B's"
-+(i.e., "B depends on A"), and requires A < B.
-+
-+resource_ids stores a "flattened" representation of the graph, as a list of
-+items (with meta data). Thus coarse ID assignment consists of the following:
-+(1) Process list of items (with old start ID and meta data) to rebuild graph.
-+(2) Traverse graph in an order that satisfies dependencies.
-+(3) When vertex A has its ID assigned, the weight of each edge "A <--" (i.e., an
-+    item) can have its weight (ID allotment) computed via quota assignment of A.
-+(4) New start IDs satisfy A + w <= B for each edge A <-- B with weight w > 0.
-+
-+The key algorithm challenge is (1). Note that it does not need weight details,
-+so we only assume A < B whenever A <-- B. Now we're faced with 2 subproblems:
-+(1a) How to represent the graph as a list of integers (with meta data)?
-+(1b) Given the list representation, how to recover the graph?
-+
-+For (1a), we start with DFS traversal of the (transposed, i.e., reversed) graph
-+starting from S, and apply the following:
-+* For each edge A <-- B traversed, emit A into sequence,
-+* Traverse a B <-- Y only when all X <-- B have been traversed.
-+
-+The resulting sequence has the length as the number of edges, and has the useful
-+property that a vertex's dependencies always appear before the vertex itself!
-+Note this the sentinel T is omitted.
-+
-+Example 1:
-+  S <-- A <-- B <-- C <-- T  => "SABC".
-+
-+Example 2:
-+  S <-- A <-- B <-- C <-- T  => "SA|AB|SDEC|SF",
-+  |     |     |     |     |  or "SF|SA|AB|SDEC",
-+  |     + <-- +     |     |  or "SDE|SA|ABC|SF",
-+  |                 |     |  or "SF|SDE|SA|ABC".
-+  + <---D <-- E <---+     |
-+  |                       |
-+  + <-- F <---------------+
-+
-+Here, "X|Y" denotes backtracking between visiting X and visiting Y. This appears
-+if and only if X >= Y, so "|" an optional (but illustrative) character that's
-+not in the actual output. We will use it consistently in comments, and so the
-+absence of "|" denotes the converse. For example, "XY" implies X < Y.
-+
-+In terms of the basic operations:
-+* Start: S <-- T => "S".
-+* Operation 1: "...AB..." => "...ACB..." (or "...A" => "...AB").
-+* Operation 2: "...AB..." => "...A|AB..." (or "...A" => "...A|A").
-+
-+For Example 2, a viable "evolution path" is:
-+"S" => "S|S" => "SC|S" => "S|SC|S" => "SA|SC|S" => "SAB|SC|S" => "SA|AB|SC|S"
-+    => "SA|AB|SDC|S" => "SA|AB|SDEC|S" => "SA|AB|SDEC|SF".
-+(Alternative: "S|S" => "S|SC" => etc.).
-+
-+Note: {A, ...} are *unlabelled* integers, and "spurious equalities" such as
-+A = D or A = F can occur!
-+
-+For (1b), we wish to build the graph from the sequence. This requires (1a) to be
-+injective (up to isomorphism). Unfortunately, this does not always hold.
-+Example:
-+  S <-- A <-- C <-- D <-- T  => "SA|SBCD".
-+  |           |
-+  + <-- B <---+
-+vs.
-+  S <----- A <----- D <-- T  => "SA|SBCD".
-+  |                 |
-+  + <-- B <-- C <---+
-+
-+To fix this, we prepend a "join" label (*) to each vertex that has multiple
-+dependencies. With this, the example above produce different results:
-+   "SA|SB*CD" != "SA|SBC*D".
-+
-+Unfortunately, this is also inadequate.  Example:
-+  S <-------- B <-- T  => "S|S|S|S*A*B",
-+  |           |
-+  + <---------+
-+  |           |
-+  + <-- A <---+
-+  |     |
-+  + <---+
-+vs.
-+  S <-------- B <-- T  => "S|S|S|S*A*B".
-+  |           |
-+  + <---A <---+
-+  |     |
-+  + <---+
-+  |     |
-+  + <---+
-+
-+To fix this, we also label the number of dependencies. In text representation,
-+we just show multiple (#dependencies - 1) copies of '*'. Now we have:
-+  "S|S|S|S*A**B" != "S|S|S|S**A*B".
-+
-+The "join" label with count adequately addresses the issue (proof omitted). In
-+the resource_ids files, these are stored as the "join" field of an item's meta
-+data.
-+
-+Additional comments for (1b) and other steps are detailed below.

-+#
-+# In general, code should depend on the static library. However, if the
-+# generated files are only processed by other actions to generate other
-+# files, it is possible to depend on the script target directly.
-+#

-+#       Path to .grd file.
-+#
-+#   enable_input_discovery_for_gn_analyze (default=true)

-+#       in order to discover all files that affect this target.
-+#       Turn this off when the .grd file is generated, or an <include> with
-+#       flattenhtml=true points to a generated file.
-+#       For "gn analyze" to be correct with this arg disabled, all inputs
-+#       must be listed via |inputs|.
-+#
-+#   inputs  (optional)
-+#       List of additional files, required for grit to process source file.
-+#
-+#   outputs (required)
-+#       List of outputs from grit, relative to the target_gen_dir. Grit will
-+#       verify at build time that this list is correct and will fail if there
-+#       is a mismatch between the outputs specified by the .grd file and the
-+#       outputs list here.
-+#
-+#       To get this list, you can look in the .grd file for
-+#       <output filename="..." and put those filename here. The base directory
-+#       of the list in Grit and the output list specified in the GN grit target
-+#       are the same (the target_gen_dir) so you can generally copy the names
-+#       exactly.
-+#
-+#       To get the list of outputs programatically, run:
-+#           python tools/grit/grit_info.py --outputs . path/to/your.grd
-+#       And strip the leading "./" from the output files.
-+#
-+#   defines (optional)
-+#       Extra defines to pass to grit (on top of the global grit_defines list).
-+#
-+#   grit_flags (optional)
-+#       List of strings containing extra command-line flags to pass to Grit.
-+#
-+#   resource_ids (optional)
-+#       Path to a grit "firstidsfile". Default is
-+#       //tools/gritsettings/resource_ids. Set to "" to use the value specified
-+#       in the <grit> nodes of the processed files.
-+#
-+#   output_dir (optional)

-+#       want to specify output_name if the target name is not particularly
-+#       unique, since this can cause files from multiple grit targets to
-+#       overwrite each other.
-+#
-+#   output_name (optional)
-+#       Provide an alternate base name for the generated files, like the .d
-+#       files. Normally these are based on the target name and go in the
-+#       output_dir, but if multiple targets with the same name end up in
-+#       the same output_dir, they can collide.
-+#
-+#   configs (optional)
-+#       List of additional configs to be applied to the generated target.
-+#
-+#   deps  (optional)
-+#   testonly (optional)
-+#   visibility  (optional)
-+#       Normal meaning.

-+# Example
-+#
-+#   grit("my_resources") {

-+Six is a Python 2 and 3 compatibility library.  It provides utility functions
-+for smoothing over the differences between the Python versions with the goal of
-+writing Python code that is compatible on both Python versions.  See the
-+documentation for more information on what is provided.
-+
-+Six supports every Python version since 2.6.  It is contained in only one Python
-+file, so it can be easily copied into your project. (The copyright and license
-+notice must be retained.)
-+
-+Online documentation is at https://pythonhosted.org/six/.
-+
-+Bugs can be reported to https://bitbucket.org/gutworth/six.  The code can also
-+be found there.
-+
-+For questions about six or porting in general, email the python-porting mailing
-+list: https://mail.python.org/mailman/listinfo/python-porting

+Upstream 8602f604e0 removed code sending BYEs which breaks some of
+our wpt.  They've opened a bug for a real fix here:

+Subject: Bug 1876896 - WebRTC backport: Allow VideoCaptureModulePipeWire to be
+ shared with more consumers r=pehrsons,webrtc-reviewers
 
-This patch addes trampoline headers for libvpx.
+This is a simple backport of an WebRTC upstream change.
 
-To follow the libwebrtc merge procedure, the vpx headers are silently
-replaced with "trampoline" headers, which do nothing but include real
-VPX headers. This makes the libwebrtc-merge process easier without
-worrying headers' paths.
+Upstream commit: 958c9ac546f33716d097b5092515dcac705151d3
 
-On the other hand, the `rtc_build_libvpx` is set to `true` in
-webrtc.gni, so moz.build file for third_party/libvpx can be generated by
-the gn_processor in the next patch.

-// You may access members of a reference-counted object, including the AddRef()
-// and Release() methods, only if you already own a reference to it, or if
-// you're borrowing someone else's reference. (A newly created object is a
-// special case: the reference count is zero on construction, and the code that
-// creates the object should immediately call AddRef(), bringing the reference
-// count from zero to one, e.g., by constructing an rtc::scoped_refptr).
-//
-// AddRef() creates a new reference to the object.
-//
-// Release() releases a reference to the object; the caller now has one less
-// reference than before the call. Returns kDroppedLastRef if the number of
-// references dropped to zero because of this (in which case the object destroys
-// itself). Otherwise, returns kOtherRefsRemained, to signal that at the precise
-// time the caller's reference was dropped, other references still remained (but
-// if other threads own references, this may of course have changed by the time
-// Release() returns).
-//
-// The caller of Release() must treat it in the same way as a delete operation:
-// Regardless of the return value from Release(), the caller mustn't access the
-// object. The object might still be alive, due to references held by other
-// users of the object, but the object can go away at any time, e.g., as the
-// result of another thread calling Release().
-//
-// Calling AddRef() and Release() manually is discouraged. It's recommended to
-// use rtc::scoped_refptr to manage all pointers to reference counted objects.
