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.

This means -that if you talloc_free() the context then the new child disappears as -well.
