2016-05-13Have wmem conform to checkAPIs.plMichael Mann1-3/+3
Yes, the rename of structure members is a bit hacky. Yes, catering to Windows since "GLib's v*printf routines are surprisingly slow on Windows". But it does pass checkAPIs.pl Change-Id: I5b1552472c83aa2e159f17b5b7eb70b37d03eff9 Reviewed-on: https://code.wireshark.org/review/15404 Reviewed-by: Michael Mann <mmann78@netscape.net>

2013-06-19Rework wmem scoping limits so that users can still get a handle to a pool whenEvan Huus1-0/+1
it is out of scope, they just can't *allocate* in the pool. This is necessary because file-scope trees (migrating from emem) are set up on program initialization when there is no file in scope - they need to initialize with the handle, they just won't use it until a file is actually in scope. svn path=/trunk/; revision=50046
2013-05-22Minor refactor: make the framework responsible for allocating and freeing theEvan Huus1-1/+1
actual wmem_allocator_t structure. This simplifies the internal API and deduplicates a few alloc/free calls in the individual allocator implementations. I'd originally made the allocators responsible for this on purpose with the idea that they'd be able to optimize something clever based on the type of allocator, but that's clearly more work and complexity than it's worth given the small number of allocators we create/destroy. svn path=/trunk/; revision=49512
2013-05-08Round two of wmem cleanup callbacks. While the emem tree behaviour will requireEvan Huus1-1/+2
recurring callbacks, I suspect most other potential uses will be once-only, so make that possible, and improve the documentation on the remaining issues. Also separate out the code into its own files and the testing into its own test case. svn path=/trunk/; revision=49209
2013-05-07Add user callbacks to wmem. This feature is a generic way to transparently mimicEvan Huus1-4/+8
the behaviour emem has for seasonal trees, which is that the master tree structure is not actually seasonal - it is permanent. When the seasonal memory pool is cleared, the root node pointer in all of these permanent trees is set to NULL, and the pool takes care of actually freeing the nodes. Wmem can now mimic this by allocating the tree header struct in epan_scope(), allocating any node structs in file_scope(), and registering a callback on file_scope() that NULLs the pointer in the epan_scope() header. Yes, this is confusing, but it seemed simpler than adding manual callback registrations to every single dissector that currently uses seasonal trees. The callbacks may also be useful for other things that need cleanup (I'm thinking resource handles stored in wmem memory that need to be fclosed or what-have-you before they the handle is lost). As indicated by the number of caveats in README.wmem, the implementation probably needs a bit of work to make it safer/saner/more-useful. Thoughts (or patches!) in this direction are more than welcome. svn path=/trunk/; revision=49205
