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 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(). Unlike talloc(), it is not type +safe (as it returns a void *), so you are on your own for type checking. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +(typeof(ptr)) talloc_ptrtype(const void *ctx, ptr); + +The talloc_ptrtype() macro should be used when you have a pointer and +want to allocate memory to point at with this pointer. When compiling +with gcc >= 3 it is typesafe. 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.

It is +particularly useful for creating a new temporary working context. + + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +(type *)talloc_realloc(const void *context, void *ptr, type, count); + +The talloc_realloc() macro changes the size of a talloc +pointer. The "count" argument is the number of elements of type "type" +that you want the resulting pointer to hold. + +talloc_realloc() has the following equivalences: + + talloc_realloc(context, NULL, type, 1) ==> talloc(context, type); + talloc_realloc(context, NULL, type, N) ==> talloc_array(context, type, N); + talloc_realloc(context, ptr, type, 0) ==> talloc_free(ptr); + +The "context" argument is only used if "ptr" is NULL, otherwise it is +ignored. + +talloc_realloc() returns the new pointer, or NULL on failure. The call +will fail either due to a lack of memory, or because the pointer has +more than one parent (see talloc_reference()). + + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +void *talloc_realloc_size(const void *context, void *ptr, size_t size); + +the talloc_realloc_size() function is useful when the type is not +known so the typesafe talloc_realloc() cannot be used. + + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +void *talloc_steal(const void *new_ctx, const void *ptr); + +The talloc_steal() function changes the parent context of a talloc +pointer.

Also, since swig_type_info structures store pointers to + * swig_cast_info structures and swig_cast_info structures store pointers back + * to swig_type_info structures, we need some lookup code at initialization. + * The idea is that swig generates all the structures that are needed. + * The runtime then collects these partially filled structures. + * The SWIG_InitializeModule function takes these initial arrays out of + * swig_module, and does all the lookup, filling in the swig_module.types + * array with the correct data and linking the correct swig_cast_info + * structures together. + * + * The generated swig_type_info structures are assigned staticly to an initial + * array. We just loop through that array, and handle each type individually. + * First we lookup if this type has been already loaded, and if so, use the + * loaded structure instead of the generated one. Then we have to fill in the + * cast linked list. The cast data is initially stored in something like a + * two-dimensional array. Each row corresponds to a type (there are the same + * number of rows as there are in the swig_type_initial array). Each entry in + * a column is one of the swig_cast_info structures for that type. + * The cast_initial array is actually an array of arrays, because each row has + * a variable number of columns. So to actually build the cast linked list, + * we find the array of casts associated with the type, and loop through it + * adding the casts to the list. The one last trick we need to do is making + * sure the type pointer in the swig_cast_info struct is correct. + * + * First off, we lookup the cast->type name to see if it is already loaded. + * There are three cases to handle: + * 1) If the cast->type has already been loaded AND the type we are adding + * casting info to has not been loaded (it is in this module), THEN we + * replace the cast->type pointer with the type pointer that has already + * been loaded. + * 2) If BOTH types (the one we are adding casting info to, and the + * cast->type) are loaded, THEN the cast info has already been loaded by + * the previous module so we just ignore it. + * 3) Finally, if cast->type has not already been loaded, then we add that + * swig_cast_info to the linked list (because the cast->type) pointer will + * be correct. + * ----------------------------------------------------------------------------- */ + +#ifdef __cplusplus +extern "C" { +#if 0 +} /* c-mode */ +#endif +#endif + +#if 0 +#define SWIGRUNTIME_DEBUG +#endif + + +SWIGRUNTIME void +SWIG_InitializeModule(void *clientdata) { + size_t i; + swig_module_info *module_head, *iter; + int found, init; + + clientdata = clientdata; + + /* check to see if the circular list has been setup, if not, set it up */ + if (swig_module.next==0) { + /* Initialize the swig_module */ + swig_module.type_initial = swig_type_initial; + swig_module.cast_initial = swig_cast_initial; + swig_module.next = &swig_module; + init = 1; + } else { + init = 0; + } + + /* Try and load any already created modules */ + module_head = SWIG_GetModule(clientdata); + if (!module_head) { + /* This is the first module loaded for this interpreter */ + /* so set the swig module into the interpreter */ + SWIG_SetModule(clientdata, &swig_module); + module_head = &swig_module; + } else { + /* the interpreter has loaded a SWIG module, but has it loaded this one?
