delta/libgit2.git/src/alloc.c, branch ethomson/github_actions github.com: libgit2/libgit2.git allocators: extract crtdbg allocator into its own file 2019-02-21T12:23:54+00:00 Patrick Steinhardt ps@pks.im 2019-02-21T11:27:42+00:00 48727e5d3bc0922a2073b717a6ee449e9bb0ddd7 The Windows-specific crtdbg allocator is currently mixed into the crtdbg stacktracing compilation unit, making it harder to find than necessary. Extract it and move it into the new "allocators/" subdirectory to improve discoverability. This change means that the crtdbg compilation unit is now compiled unconditionally, whereas it has previously only been compiled on Windows platforms. Thus we now have additional guards around the code so that it will only be compiled if GIT_MSVC_CRTDBG is defined. This also allows us to move over the fallback-implementation of `git_win32_crtdbg_init_allocator` into the same compilation unit.

allocators: move standard allocator into subdirectory 2019-02-21T11:28:02+00:00 Patrick Steinhardt ps@pks.im 2019-02-21T11:13:59+00:00 b63396b75fe26afa3b27259c0d13dd7bc13b53ba Right now, our two allocator implementations are scattered around the tree in "stdalloc.h" and "win32/w32_crtdbg_stacktrace.h". Start grouping them together in a single directory "allocators/", similar to how e.g. our streams are organized.

git_error: use new names in internal APIs and usage 2019-01-22T22:30:35+00:00 Edward Thomson ethomson@edwardthomson.com 2018-12-27T19:47:34+00:00 f673e232afe22eb865cdc915e55a2df6493f0fbb Move to the `git_error` name in the internal API for error-related functions.

alloc: don't overwrite allocator during init if set 2018-07-15T15:30:04+00:00 Carlos Martín Nieto cmn@dwim.me 2018-07-15T15:30:04+00:00 19007b19b70504a3964f5d8320d0ef39c01ce6b0 If the allocator has been set before we the library is initialised, we would replace that setting with the standard allocator contrary to the user's wishes.

settings: allow swapping out memory allocator 2018-06-07T10:57:39+00:00 Patrick Steinhardt ps@pks.im 2018-03-16T10:14:50+00:00 74b7ddbf333ee20a4b2bc7a0e7c3f7c2aa4fc590 Tie in the newly created infrastructure for swapping out memory allocators into our settings code. A user can now simply use the new option "GIT_OPT_SET_ALLOCATOR" with `git_libgit2_opts`, passing in an already initialized allocator structure as vararg.

alloc: make memory allocators use function pointers 2018-06-07T10:57:39+00:00 Patrick Steinhardt ps@pks.im 2018-03-20T14:23:49+00:00 9865cd1696ac4a3f47991a9a1d79b17cef5edc89 Currently, our memory allocators are being redirected to the correct implementation at compile time by simply using macros. In order to make them swappable at runtime, this commit reshuffles that by instead making use of a global "git_allocator" structure, whose pointers are set up to reference the allocator functions. Like this, it becomes easy to swap out allocators by simply setting these function pointers. In order to initialize a "git_allocator", our provided allocators "stdalloc" and "crtdbg" both provide an init function. This is being called to initialize a passed in allocator struct and set up its members correctly. No support is yet included to enable users of libgit2 to switch out the memory allocator at a global level.
