lhchavez 2f382ab7 2021-01-20T04:40:40 mwindow: Fix a bug in the LRU window finding code This change now updates the `lru_window` variable to match the current file's MRU window. This makes it such that it doesn't always choose the file that happened to come last in the list of window files, and instead should now correctly choose the file with the least-recently-used one.

Edward Thomson 923c0f7b 2021-01-07T17:34:17 clone: set refs/remotes/origin/HEAD when branch is specified When a branch is specified to check out in clone, update the remote tracking `HEAD` to point to it. This mimics git's behavior, when `git clone -b <name>` is used.

lhchavez ff6f6754 2021-01-07T05:44:16 Use `p_pwrite`/`p_pread` consistently throughout the codebase This change stops using the seek+read/write combo to perform I/O with an offset, since this is faster by one system call (and also more atomic and therefore safer).

Edward Thomson 3f4bc213 2021-01-07T14:05:02 repo: ignore empty init.defaultbranch The init.defaultbranch option may be set, but empty. In this case, we should ignore it instead of trying to set our default branch to `refs/heads/`.
Edward Thomson 32350e89 2021-01-07T14:01:30 remote: don't update invalid refs If a symbolic reference points to something invalid, then do not try to update it.
Edward Thomson c41871e5 2021-01-07T12:22:08 fetch: test when HEAD points to nonexistent branch When HEAD points to a nonexistent or invalid branch - for example, to `refs/heads/` - the fetch should be permitted to continue, but we should not use it when creating the `for merge` option in the FETCH_HEAD file. (This emulates git's behavior.)

Josh Stockin 556e0747 2021-01-04T10:56:01 Move doc comment about `GIT_BLOB_FILTER_OPTIONS_VERSION` Removes doc comment on `git_blob_filter_options.version`, moves information to `git_blob_filter_options` doc comment to remain consistent with other options structures' documentation. `git_blob_filter_options_init` still needed; should be added in another commit/PR (it's out of the scope of this PR, #5759), update this documentation again.

Dhruva Krishnamurthy a9f57a89 2020-11-23T10:14:00 Remove broken support for write in emulated mmap * Emulated mmap based write without pagefault handling is not possible since IO happens outside of call to mmap and data is written to mapped memory * Potential emulation using userfaultfd() might be possible
lhchavez 83265b3e 2020-12-18T06:50:22 zlib: Add support for building with Chromium's zlib implementation This change builds libgit2 using Chromium's zlib implementation by invoking cmake with `-DUSE_BUNDLED_ZLIB=ON -DUSE_CHROMIUM_ZLIB=ON`, which is ~10% faster than the bundled zlib for the core::zstream suite. This version of zlib has some optimizations: a) Decompression (Intel+ARM): inflate_fast, adler32, crc32, etc. b) Compression (Intel): fill_window, longest_match, hash function, etc. Due to the introduction of SIMD optimizations, and to get the maximum performance out of this fork of zlib, this requires an x86_64 processor with SSE4.2 and CLMUL (anything Westmere or later, ~2010). The Chromium zlib implementation also supports ARM with NEON, but it has not been enabled in this patch. Performance =========== TL;DR: Running just `./libgit2_clar -score::zstream` 100 times in a loop took 0:56.30 before and 0:50.67 after (~10% reduction!). The bundled and system zlib implementations on an Ubuntu Focal system perform relatively similar (the bundled one is marginally better due to the compiler being able to inline some functions), so only the bundled and Chromium zlibs were compared. For a more balanced comparison (to ensure that nothing regressed overall), `libgit2_clar` under `perf` was also run, and the zlib-related functions were compared.

lhchavez 212ae9a7 2020-12-21T06:48:48 Fix the `-DENABLE_WERROR=ON` build for gcc 10.2 This change makes it possible to build with newer versions of gcc without warnings. There were two warnings issued: * gcc 8 added [`-Wstringop-truncation`](https://developers.redhat.com/blog/2018/05/24/detecting-string-truncation-with-gcc-8/), which warns if a call to `strncpy(3)` is prone to accidentally truncating the destination string, since `strncpy(3)` does NOT add a terminating `NULL` if the destination buffer is not large enough to hold the input. This change uses the pattern suggested in https://us-cert.cisa.gov/bsi/articles/knowledge/coding-practices/strncpy-and-strncat to fix the locations flagged by gcc. * There was a potentially uninitialized access of `dest` in `fs_copy`.

lhchavez 5ab0736b 2020-12-19T09:30:26 Add tests for `git__multiply_int64_overflow` As it turns out, the implementation of `git__multiply_int64_overflow` is full of edge cases and tricky arithmetic. That means that it should have unit tests. As a result, a bug in `git__strntol64` was found (and fixed!) in clang+32-bit.

This could be fixed by statically linking some compiler-rt libraries to provide this symbol, but let's first stop the bleeding since doing the correct long-term fix requires some non-trivial CMake knowledge which I lack.

Edward Thomson 589b8129 2020-12-14T10:43:07 badssl: RC4 should not fail with ECERTIFICATE Using RC4 is not a _certificate_ problem, it's a cipher problem. The SSL implementation should and will fail with an unrecoverable error (-1). There's no opportunity to accept/continue.
Carlos Martín Nieto 89ffa98e 2017-11-18T15:51:08 badssl: re-enable RC4 test This used to fail with an error indicating a mis-use of OpenSSL on platforms using it due to poor error handling. Re-enable it even if this isn't the right error code to use for now.

lhchavez e99e833f 2020-12-12T16:51:15 Make git__strntol64() ~70%* faster This change uses compiler intrinsics to detect overflows instead of using divisions to detect potential overflow. This makes the code faster and makes it easier to read as a bonus side-effect! Some of the things this quickens: * Config parsing. * Tree parsing. * Smart protocol negotiation. \* Measured by running `libgit2_clar` with `-fno-optimize-sibling-calls -fno-omit-frame-pointer` under `perf(1)`: ```shell $ perf diff --symbols=git__strntol64 --compute=ratio \ --percentage=absolute baseline.data perf.data \# Event 'cycles' \# \# Baseline Ratio Shared Object \# ........ .............. ............. \# 0.25% 0.321836 libgit2_clar ```

lhchavez 41da4e16 2020-12-10T19:52:01 Cache the parsed submodule config when diffing This change makes that anything that calls `git_diff__from_iterators` (any of the `git_diff_xxx` functions) only need to parse the `.gitmodules` file once. This can be avoided by calling `git_repository_submodule_cache_all(...)`, but we can do that safely for the user with no change in semantics. Fixes: #5725

Edward Thomson 08f28ff5 2020-07-10T08:57:05 alloc: set up an allocator that fails before library init We require the library to be initialized with git_libgit2_init before it is functional. However, if a user tries to uses the library without doing so - as they might when getting started with the library for the first time - we will likely crash. This commit introduces some guard rails - now instead of having _no_ allocator by default, we'll have an allocator that always fails, and never tries to set an error message (since the thread-local state is set up by git_libgit2_init). We've modified the error retrieval function to (try to) ensure that the library has been initialized before getting the thread-local error message. (Unfortunately, we cannot determine if the thread local storage has actually been configured, this does require initialization by git_libgit2_init. But a naive attempt should be good enough for most cases.)
Edward Thomson 6c51014d 2020-07-11T14:24:17 libgit2: provide init_count of the library A function to provide the initialization count of the library; this is subject to race conditions but is useful for a naive determination as to whether the library has been initialized or not.

Edward Thomson 42d5f110 2020-12-08T14:33:31 win32: provide macros for calling conventions Provide more clarity for Win32 calling conventions - now that we always compile to __cdecl on Win32, we'll define that as the the libgit2 calling convention. Also offer NTAPI (__stdcall) calling conventions for things that need callbacks from NTAPI code (eg fiber-local storage).
Tyler Ang-Wanek 971b7187 2020-08-06T16:24:18 Implement generic TLS interface This adds a generic TLS interface for anyone to store TLS data. It is designed to work regardless of whether threading support is built into the library or not. Nobody in the library should directly interface with the data on the TLS struct, so it's been built to be opaque even in the library. Requires the allocator to be initialized before use.
