Patrick Steinhardt 48727e5d 2019-02-21T12:27:42 allocators: extract crtdbg allocator into its own file 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.
Patrick Steinhardt b63396b7 2019-02-21T12:13:59 allocators: move standard allocator into subdirectory 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.
Edward Thomson f673e232 2018-12-27T13:47:34 git_error: use new names in internal APIs and usage Move to the `git_error` name in the internal API for error-related functions.
Edward Thomson 305e801a 2018-10-21T09:52:32 util: allow callers to reset custom allocators Provide a utility to reset custom allocators back to their default. This is particularly useful for testing.
Carlos Martín Nieto 19007b19 2018-07-15T17:30:04 alloc: don't overwrite allocator during init if set 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.
Patrick Steinhardt 74b7ddbf 2018-03-16T10:14:50 settings: allow swapping out memory allocator 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.
Patrick Steinhardt 9865cd16 2018-03-20T14:23:49 alloc: make memory allocators use function pointers 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.
