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 mounthful 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 uses 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 ; +- the context returned by talloc_autofree_context() is also global so +shouldn't be used by several threads simultaneously without +synchronization. + + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +(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. This means +that if you talloc_free() the context then the new child disappears as +well. Alternatively you can free just the child. + +The context argument to talloc() can be NULL, in which case a new top +level context is created. + + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +void *talloc_size(const void *context, size_t size); + +The function talloc_size() should be used when you don't have a +convenient type to pass to talloc().

Note this is a wrapper of talloc_size() +and talloc_get_name() will return the current location in the source file. +and not the type. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +int talloc_free(void *ptr); + +The talloc_free() function frees a piece of talloc memory, and all its +children. 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. The only 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. + +If this pointer has an additional parent when talloc_free() is called +then the memory is not actually released, but instead the most +recently established parent is destroyed.

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. That will destroy the + most recently established parent to the pointer and leave the + pointer as a child of its current parent. + +For more control on which parent to remove, see talloc_unlink() + + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +int talloc_unlink(const void *context, const void *ptr); + +The talloc_unlink() function removes a specific parent from ptr. The +context passed must either be a context used in talloc_reference() +with this pointer, or must be a direct parent of ptr. + +Note that if the parent has already been removed using talloc_free() +then this function will fail and will return -1. Likewise, if "ptr" +is NULL, then the function will make no modifications and return -1. + +Usually you can just use talloc_free() instead of talloc_unlink(), but +sometimes it is useful to have the additional control on which parent +is removed. + + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +void talloc_set_destructor(const void *ptr, int (*destructor)(void *)); + +The function talloc_set_destructor() sets the "destructor" for the +pointer "ptr". A destructor is a function that is called when the +memory used by a pointer is about to be released. 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. This would be a pointless operation anyway, as the +destructor is only called when the memory is just about to go away. + + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +int talloc_increase_ref_count(const void *ptr); + +The talloc_increase_ref_count(ptr) function is exactly equivalent to: + + talloc_reference(NULL, ptr); + +You can use either syntax, depending on which you think is clearer in +your code. + +It returns 0 on success and -1 on failure. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +size_t talloc_reference_count(const void *ptr); + +Return the number of references to the pointer. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +void talloc_set_name(const void *ptr, const char *fmt, ...); + +Each talloc pointer has a "name". The name is used principally for +debugging purposes, although it is also possible to set and get the +name on a pointer in as a way of "marking" pointers in your code. + +The main use for names on pointer is for "talloc reports". See +talloc_report() and talloc_report_full() for details. Also see +talloc_enable_leak_report() and talloc_enable_leak_report_full(). + +The talloc_set_name() function allocates memory as a child of the +pointer.

It is extensively +used by the "auto naming" macros, such as talloc_p(). + +This function does not allocate any memory.
