It is a logical +unit which represents a memory space managed by talloc. + +From the programmer's point of view, the talloc context is completely +equivalent to a pointer that would be returned by the memory routines from the +C standard library. This means that every context that is returned from the +talloc library can be used directly in functions that do not use talloc +internally. For example we can do the following: + +@code +char *str1 = strdup("I am NOT a talloc context"); +char *str2 = talloc_strdup(NULL, "I AM a talloc context"); + +printf("%d\n", strcmp(str1, str2) == 0); + +free(str1); +talloc_free(str2); /* we can not use free() on str2 */ +@endcode + +This is possible because the context is internally handled as a special +fixed-length structure called talloc chunk. Each chunk stores context metadata +followed by the memory space requested by the programmer. When a talloc +function returns a context (pointer), it will in fact return a pointer to the user +space portion of the talloc chunk. If we to manipulate this context using +talloc functions, the talloc library transforms the user-space pointer back to +the starting address of the chunk. This is also the reason why we were unable +to use <code>free(str2)</code> in the previous example - because +<code>str2</code> does not point at the beginning of the allocated block of +memory. This is illustrated on the next image: + +@image html context.png + +The type TALLOC_CTX is defined in talloc.h to identify a talloc context in +function parameters. However, this type is just an alias for <code>void</code> +and exists only for semantical reasons - thus we can differentiate between +<code>void *</code> (arbitrary data) and <code>TALLOC_CTX *</code> (talloc +context). + +@subsection metadata Context meta data + +Every talloc context carries several pieces of internal information along with +the allocated memory: + + - name - which is used in reports of context hierarchy and to simulate + a dynamic type system, + - size of the requested memory in bytes - this can be used to determine + the number of elements in arrays, + - attached destructor - which is executed just before the memory block is + about to be freed, + - references to the context + - children and parent contexts - create the hierarchical view on the + memory. + +@section context-hierarchy Hierarchy of talloc context + +Every talloc context contains information about its parent and children. Talloc +uses this information to create a hierarchical model of memory or to be more +precise, it creates an n-ary tree where each node represents a single talloc +context. The root node of the tree is referred to as a top level context - a +context without any parent. + +This approach has several advantages: + + - as a consequence of freeing a talloc context, all of its children + will be properly deallocated as well, + - the parent of a context can be changed at any time, which + results in moving the whole subtree under another node, + - it creates a more natural way of managing data structures. + +@subsection Example + +We have a structure that stores basic information about a user - his/her name, +identification number and groups he/she is a member of: + +@code +struct user { + uid_t uid; + char *username; + size_t num_groups; + char **groups; +}; +@endcode + +We will allocate this structure using talloc. The result will be the following +context tree: + +@image html context_tree.png + +@code +/* create new top level context */ +struct user *user = talloc(NULL, struct user); + +user->uid = 1000; +user->num_groups = N; + +/* make user the parent of following contexts */ +user->username = talloc_strdup(user, "Test user"); +user->groups = talloc_array(user, char*, user->num_groups); + +for (i = 0; i < user->num_groups; i++) { + /* make user->groups the parent of following context */ + user->groups[i] = talloc_asprintf(user->groups, + "Test group %d", i); +} +@endcode + +This way, we have gained a lot of additional capabilities, one of which is +very simple deallocation of the structure and all of its elements. + +With the C standard library we need first to iterate over the array of groups +and free every element separately. Then we must deallocate the array that stores +them. Next we deallocate the username and as the last step free the structure +itself. But with talloc, the only operation we need to execute is freeing the +structure context.

It won't write your +bindings for you but it will make it easier to write C bindings that involve +talloc, and take away some of the boiler plate. + +Python 3 +-------- + +pytalloc can be used with Python 3. Usage from Python extension remains +the same, but for the C utilities, the library to link to is tagged with +Python's PEP3149 ABI tag, for example "pytalloc.cpython34m". +To make a build for Python 3, configure with PYTHON=/usr/bin/python3. +. +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +pytalloc_Object / pytalloc_BaseObject + +This is the new base class that all Python objects that wrap talloc pointers +derive from. It is itself a subclass of the "Object" type that all objects +in Python derive from. + +Note that you will almost never create objects of the pytalloc_Object type +itself, as they are just opaque pointers that can not be accessed from +Python. A common pattern is other objects that subclass pytalloc_Object and +rely on it for their memory management. + +Each `pytalloc_Object` wraps two core of information - a talloc context +and a pointer. The pointer is the actual data that is wrapped. The talloc +context is used for memory management purposes only; when the wrapping Python object +goes away, it unlinks the talloc context. The talloc context pointer and the ptr +can (and often do) have the same value. + +Each pytalloc_Object has a custom __repr__ implementation that +describes that it is a talloc object and the location of the +pointer it is wrapping. it also has a custom __cmp__/__eq__/__neq__ method that +compares the pointers the object is wrapping rather than the objects +themselves (since there can be multiple objects that wrap the same talloc +pointer). + +It is preferred to use pytalloc_BaseObject as this implementation +exposes less in the C ABI and correctly supports pointers in C arrays +in the way needed by PIDL. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +PyTypeObject *pytalloc_GetObjectType(void) + +Obtain a pointer to the PyTypeObject for `pytalloc_Object`.

With 3.0.20 (or 3.0.14?) the +Samba4 talloc has been ported back to Samba3, so this guide applies to both. + +The new talloc is a hierarchical, reference counted memory pool system +with destructors. Quite a mouthful really, but not too bad once you +get used to it. + +Perhaps the biggest change from Samba3 is that there is no distinction +between a "talloc context" and a "talloc pointer". Any pointer +returned from talloc() is itself a valid talloc context. This means +you can do this:: + + struct foo *X = talloc(mem_ctx, struct foo); + X->name = talloc_strdup(X, "foo"); + +and the pointer X->name would be a "child" of the talloc context "X" +which is itself a child of "mem_ctx". So if you do talloc_free(mem_ctx) +then it is all destroyed, whereas if you do talloc_free(X) then just X +and X->name are destroyed, and if you do talloc_free(X->name) then +just the name element of X is destroyed. + +If you think about this, then what this effectively gives you is an +n-ary tree, where you can free any part of the tree with +talloc_free(). + +If you find this confusing, then I suggest you run the testsuite to +watch talloc in action. You may also like to add your own tests to +testsuite.c to clarify how some particular situation is handled. + + +Performance +----------- + +All the additional features of talloc() over malloc() do come at a +price. We have a simple performance test in Samba4 that measures +talloc() versus malloc() performance, and it seems that talloc() is +about 4% slower than malloc() on my x86 Debian Linux box. For Samba, +the great reduction in code complexity that we get by using talloc +makes this worthwhile, especially as the total overhead of +talloc/malloc in Samba is already quite small. + + +talloc API +---------- + +The following is a complete guide to the talloc API. Read it all at +least twice. + +Multi-threading +--------------- + +talloc itself does not deal with threads. It is thread-safe (assuming +the underlying "malloc" is), as long as each thread uses different +memory contexts. +If two threads use the same context then they need to synchronize in +order to be safe. In particular: +- when using talloc_enable_leak_report(), giving directly NULL as a +parent context implicitly refers to a hidden "null context" global +variable, so this should not be used in a multi-threaded environment +without proper synchronization. In threaded code turn off null tracking using +talloc_disable_null_tracking(). ; +- the context returned by talloc_autofree_context() is also global so +shouldn't be used by several threads simultaneously without +synchronization. + +talloc and shared objects +------------------------- + +talloc can be used in shared objects. Special care needs to be taken +to never use talloc_autofree_context() in code that might be loaded +with dlopen() and unloaded with dlclose(), as talloc_autofree_context() +internally uses atexit(3). Some platforms like modern Linux handles +this fine, but for example FreeBSD does not deal well with dlopen() +and atexit() used simultaneously: dlclose() does not clean up the list +of atexit-handlers, so when the program exits the code that was +registered from within talloc_autofree_context() is gone, the program +crashes at exit. + + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +(type *)talloc(const void *context, type); + +The talloc() macro is the core of the talloc library. It takes a +memory context and a type, and returns a pointer to a new area of +memory of the given type. + +The returned pointer is itself a talloc context, so you can use it as +the context argument to more calls to talloc if you wish. + +The returned pointer is a "child" of the supplied context.

You can call talloc_free() on any pointer returned by +talloc(). + +The return value of talloc_free() indicates success or failure, with 0 +returned for success and -1 for failure. A possible failure condition +is if the pointer had a destructor attached to it and the destructor +returned -1. See talloc_set_destructor() for details on +destructors. Likewise, if "ptr" is NULL, then the function will make +no modifications and returns -1. + +From version 2.0 and onwards, as a special case, talloc_free() is +refused on pointers that have more than one parent associated, as talloc +would have no way of knowing which parent should be removed. This is +different from older versions in the sense that always the reference to +the most recently established parent has been destroyed. Hence to free a +pointer that has more than one parent please use talloc_unlink(). + +To help you find problems in your code caused by this behaviour, if +you do try and free a pointer with more than one parent then the +talloc logging function will be called to give output like this: + + ERROR: talloc_free with references at some_dir/source/foo.c:123 + reference at some_dir/source/other.c:325 + reference at some_dir/source/third.c:121 + +Please see the documentation for talloc_set_log_fn() and +talloc_set_log_stderr() for more information on talloc logging +functions. + +talloc_free() operates recursively on its children. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +void talloc_free_children(void *ptr); + +The talloc_free_children() walks along the list of all children of a +talloc context and talloc_free()s only the children, not the context +itself. + +A NULL argument is handled as no-op. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +void *talloc_reference(const void *context, const void *ptr); + +The talloc_reference() function makes "context" an additional parent +of "ptr". + +The return value of talloc_reference() is always the original pointer +"ptr", unless talloc ran out of memory in creating the reference in +which case it will return NULL (each additional reference consumes +around 48 bytes of memory on intel x86 platforms). + +If "ptr" is NULL, then the function is a no-op, and simply returns NULL. + +After creating a reference you can free it in one of the following +ways: + + - you can talloc_free() any parent of the original pointer. That + will reduce the number of parents of this pointer by 1, and will + cause this pointer to be freed if it runs out of parents. + + - you can talloc_free() the pointer itself if it has at maximum one + parent.

The destructor +receives the pointer as an argument, and should return 0 for success +and -1 for failure. + +The destructor can do anything it wants to, including freeing other +pieces of memory. A common use for destructors is to clean up +operating system resources (such as open file descriptors) contained +in the structure the destructor is placed on. + +You can only place one destructor on a pointer. If you need more than +one destructor then you can create a zero-length child of the pointer +and place an additional destructor on that. + +To remove a destructor call talloc_set_destructor() with NULL for the +destructor. + +If your destructor attempts to talloc_free() the pointer that it is +the destructor for then talloc_free() will return -1 and the free will +be ignored.
