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.
Patrick Steinhardt 03dc6480 2019-01-02T09:27:44 hash: convert `global_init` macros to real function The `git_hash_global_init` function is simply defined as a macro to zero for most of the different hash implementations. This makes it impossible to treat it like a function pointer, which is required for a later commit where we want to improve the way global initialization works. Fix the issue by converting all no-op macros to an inline function returning zero. There's a small gotcha here, though: as most hash implementations only have a header file, but not a corresponding implementation file, we cannot declare the function as non-static. But declaring it as `static inline` fails, too, as there is a previous declaration as non-static. So we have to move the function declaration after the include that brings in the function definition, as it is allowed to have a non-static declaration after a static definition, but not the other way round.

Patrick Steinhardt 75e1737a 2017-12-08T10:10:19 hash: openssl: check return values of SHA1_* functions The OpenSSL functions `SHA1_Init`, `SHA1_Update` and `SHA1_Final` all return 1 for success and 0 otherwise, but we never check their return values. Do so.
Edward Thomson bdb54214 2017-12-11T16:46:05 hash: commoncrypto hash should support large files Teach the CommonCrypto hash mechanisms to support large files. The hash primitives take a `CC_LONG` (aka `uint32_t`) at a time. So loop to give the hash function at most an unsigned 32 bit's worth of bytes until we have hashed the entire file.
Edward Thomson a89560d5 2017-12-10T17:26:43 hash: win32 hash mechanism should support large files Teach the win32 hash mechanisms to support large files. The hash primitives take at most `ULONG_MAX` bytes at a time. Loop, giving the hash function the maximum supported number of bytes, until we have hashed the entire file.
Patrick Steinhardt 0c7f49dd 2017-06-30T13:39:01 Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.

Carlos Martín Nieto 799e22ea 2014-10-23T17:34:41 Rename git_threads_ to git_libgit2_ This describes their purpose better, as we now initialize ssl and some other global stuff in there. Calling the init function is not something which has been optional for a while now.

Russell Belfer a3aa5f4d 2013-09-11T12:45:20 Add simple global shutdown hooks Increasingly there are a number of components that want to do some cleanup at global shutdown time (at least if there are not going to be memory leaks). This creates a very simple system of shutdown hooks that will be invoked by git_threads_shutdown. Right now, the maximum number of hooks is hardcoded, but since adding a hook is not a public API, it should be fine and I thought it was better to start off with really simple code.
