Edward Thomson b900981c 2021-12-12T14:25:25 sha: add sha256 algorithm Add support for a SHA256 hash algorithm, and add the "builtin" SHA256 hash engine (from RFC 6234).
Edward Thomson 36df49c2 2021-12-12T14:29:11 sha: GIT_ERROR_SHA1 is deprecated in favor of GIT_ERROR_SHA The more generic GIT_ERROR_SHA allows for SHA256 errors as well as SHA1.
Edward Thomson 8bc998f4 2021-12-12T12:44:13 sha1: remove generic implementation Remove the "generic" implementation; it should never be used; it only existed for a no-dependencies configuration, and our bundled sha1dc satisfies that requirement _and_ is correct.
Edward Thomson fb6d0181 2022-01-22T21:47:03 ---------------------------------
Edward Thomson c7b189ba 2021-12-12T13:19:36 sha1: refactor folder structure Eliminate the `sha1` folder, move it down into `hash` so that future impelmentations can share common code.

Edward Thomson 0e530061 2022-03-22T21:07:53 Merge pull request #6246 from bierbaum/wilhelm/fix_extension_validation_string_bug Fix a string concatenation bug when validating extensions
Wilhelm Bierbaum ecc722c3 2022-03-16T10:25:11 Fix a string parsing bug when validating extensions from the configuration As builtin extensions are evaluated in the latter half of `check_valid_extension`, a string `cfg` is concatenated with the static string 'extension.' and the value from `builtin_extension`, before being compared with the configured value. This string is not being cleared while iterating through the names of the extensions. Because there is currently only one extension ('noop'), the bug was never noticible. This patch corrects the behavior by clearing the string on each iteration, as is done in the first block.

Edward Thomson cfdf36f9 2022-02-22T21:49:15 ci: rename build setup scripts Rename our build setup scripts to include the `build` name so that we can add additional CI setup scripts with no ambiguity.
Edward Thomson 4c6eab99 2022-02-22T22:03:08 ci: run benchmark tests nightly
Edward Thomson 93037bab 2022-02-22T22:00:37 tests: add benchmark tests Add a benchmark test suite that wraps hyperfine and is suitable for producing data about test runs of a CLI or A/B testing CLIs.
Edward Thomson e48bb3b7 2022-02-22T21:52:08 ci: allow for build-time (`cmake --build`) options Allow for options in the `cmake --build` phase, so that callers can specify (eg) the config type.
Edward Thomson b08fe71d 2022-02-27T23:16:05 cmake: export libraries needed to compile against libgit2 If users are using us as a direct dependency (via `add_subdirectory`) then they may want to know the libraries to link to; tell them.
Edward Thomson 073e63d0 2022-02-27T10:05:24 object: validate that `odb_obj` was set
Edward Thomson 241d838f 2022-02-27T10:02:05 http: skip processing when body is null or 0 length Mistakenly `&&` when we should have `||`d.
Edward Thomson 9f0088c4 2022-02-27T09:26:16 fs_path: exit quickly in `dirname_r` failure When we encounter a situation where we need to exit, simply `return -1` instead of trying to set `len = -1` and then jumping to the exit handler, which would erroneously do work based on the `len` value.
Edward Thomson 043a87a0 2022-02-27T09:21:53 refdb: unlock mutex on assertion failure If we're safely asserting (and returning an error to the caller), we should still unlock our mutex.
Edward Thomson d9b041e6 2022-02-27T09:20:58 assert: add `ASSERT_WITH_CLEANUP` Now that we safely assert and return, we may need to be in a place where we need to unlock mutexes or cleanup resources. Provide `ASSERT_WITH_CLEANUP` that permits for this behavior by taking a block.
Edward Thomson e32db9f2 2022-02-27T08:54:09 cli: always give a value to `error`
Edward Thomson 1327dbcf 2022-02-26T15:10:42 Merge pull request #6133 from libgit2/ethomson/cli_redux CLI (redux)
Edward Thomson 3a3ab065 2020-05-03T23:13:28 cli: infrastructure for a cli project Introduce a command-line interface for libgit2. The goal is for it to be git-compatible. 1. The libgit2 developers can more easily dogfood libgit2 to find bugs, and performance issues. 2. There is growing usage of libgit2's examples as a client; libgit2's examples should be exactly that - simple code samples that illustrate libgit2's usage. This satisfies that need directly. 3. By producing a client ourselves, we can better understand the needs of client creators, possibly producing a shared "middleware" for commonly-used pieces of client functionality like interacting with external tools. 4. Since git is the reference implementation, we may be able to benefit from git's unit tests, running their test suite against our CLI to ensure correct behavior. This commit introduces a simple infrastructure for the CLI. The CLI is currently links libgit2 statically; this is because the utility layer is required for libgit2 _but_ shares the error state handling with libgit2 itself. There's no obviously good solution here without introducing annoying indirection or more complexity. Until we can untangle that dependency, this is a good step forward. In the meantime, we link the libgit2 object files, but we do not include the (private) libgit2 headers. This constrains the CLI to the public libgit2 interfaces.
Edward Thomson e427d0a1 2021-11-30T10:33:24 cli: add `hash-object` command Introduce a simple command that emulates `git hash-object`.

Edward Thomson b8771227 2021-11-28T10:32:03 cli: add `cat-file` command Introduce a simple command that emulates `git cat-file`.
Edward Thomson f8e7d8fd 2021-11-26T17:33:38 cli: support `help <command>` Support `help <command>` by re-invoking the command itself with the `--help` argument. This allows us to keep the help logic with the commands itself.
Edward Thomson c6dd82d9 2020-02-23T11:54:33 cli: introduce a help command Add a framework for commands to be defined, and add our first one, "help". When `git2_cli help` is run, the `cmd_help` function will be invoked with the remaining command line arguments. This allows users to invoke `git2_cli help foo` to get information about the `foo` subcommand.
Edward Thomson 8526cbd5 2021-11-26T09:37:29 opt: use a custom function to print usage Our argument parser (https://github.com/ethomson/adopt) includes a function to print a usage message based on the allowed options. Omit this and use a cutom function that understands that we have subcommands ("checkout", "revert", etc) that each have their own options.

Edward Thomson 91ba0896 2021-11-15T09:54:00 cmake: rename git2internal target to libgit2 The `git2internal` target is actually the git library; call it such so that IDE users have visibility into it.

Edward Thomson c3b7ace9 2021-11-14T16:43:53 refactor: make util an object library Instead of simply including the utility files directly, make them a cmake object library for easy reusability between other projects within libgit2. Now the top-level `src` is responsible for platform selection, while the next-level `libgit2` and `util` configurations are responsible for identifying what objects they include.
Edward Thomson ef4ab298 2021-11-14T08:47:40 refactor: `src` is now `src/libgit2`
Edward Thomson 49e180c8 2022-02-15T22:55:48 errors: expose `git_error_set` The `git_error_set` function is useful for callers who implement backends and advanced callbacks. Expose it.

Edward Thomson f45121ed 2022-02-21T16:13:52 win32: `find_system_dirs` does not return `GIT_ENOTFOUND` Allow for no Git for Windows installation. When there is no GfW found in the path or registry, `git_win32__find_system_dirs` would return a `GIT_ENOTFOUND`. Callers were not expecting this. Since this is no error, we simply return `0` so that callers can move on with their lives.

Carlos Martín Nieto e35b5e44 2022-02-21T10:34:13 test: add test for the behaviour of update_tips on error
Carlos Martín Nieto 15860aa0 2022-02-21T10:03:06 remote: do store the update_tips callback error value We use `git_error_set_after_callback_function` to determine whether `update_tips` returned an error but do not store its return value making us think it always returns 0. Fix it by adding the common patter of storing it inside the `if` when calling it.

Edward Thomson b722c45d 2022-02-17T13:55:34 xdiff: use xdl_free not free We've added a lovely abstraction layer in xdiff so that it can call our allocation functions. But it also needs to call our free functions. We missed some `free` calls in `xmerge.c`. Update them to use `xdl_free`. Without this, we will pass a pointer allocated with a custom allocator to the system free function. :bomb:

Edward Thomson ae74d5ac 2022-02-14T07:01:43 meta: update version number to v1.5.0-alpha Update the version number in main to v1.5.0-alpha. This helps people understand that the main builds are not part of the v1.4.0 release train. We use "alpha" to indicate builds out of main (or nightlies) as semver v2 requires the prerelease component is compared lexicographically. Thus, our "beta" and "rc" releases should follow.

Michał Górny 8bc9eda7 2022-02-13T21:23:56 cmake: Fix package name for system http-parser Fix building against system http-parser library by fixing the find_package() argument. It seems to have been accidentally changed from HTTPParser to HTTP_Parser in de178d36f, effectively making the build against system library fail to find it: ``` CMake Warning at cmake/SelectHTTPParser.cmake:3 (find_package): By not providing "FindHTTP_Parser.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "HTTP_Parser", but CMake did not find one.

Edward Thomson 0fbf62cd 2022-02-12T08:46:55 merge: make the internal flags public We made the flags that enable recursive merge internal, on the assumption that nobody would want them and they're hard to reason about. (Giving people an option that nobody wants is just extra noise.) However, it made it hard for _us_ to reason about. There's no good reason to keep it private, let's just make it public and push that cognitive load onto our poor users. But they should expect it, they're dealing with git, after all.
Edward Thomson d2ce981f 2022-02-11T17:54:34 diff: fail generation if a file changes size When we know that we know a file's size, and the file's size changes, fail.
Edward Thomson 359240b6 2022-02-11T17:56:05 diff: indicate when the file size is "valid" When we know the file size (because we're producing it from a working directory iterator, or an index with an up-to-date cache) then set a flag indicating as such. This removes the ambiguity about a 0 file size, which could indicate that a file exists and is 0 bytes, or that we haven't read it yet.
Edward Thomson e86e81c5 2022-02-12T06:58:05 oid: make empty tree id global Move the empty tree ID into a global space so that it can be generally used.

Iliyas Jorio 0a0cd67d 2022-02-08T20:18:15 diff_file: fix crash if size of diffed file changes in workdir "diff_file_content_load_workdir_file()" maps a file from the workdir into memory. It uses git_diff_file.size to determine the size of the memory mapping. If this value goes stale, the mmaped area would be sized incorrectly. This could occur if an external program changes the contents of the file after libgit2 had cached its size. This used to segfault if the file becomes smaller (mmaped area too large). This patch causes diff_file_content_load_workdir_file to fail without crashing if it detects that the file size has changed.

Edward Thomson 3c53796c 2022-02-07T19:38:32 rand: introduce git_rand PRNG Introduce `git_rand`, a PRNG based on xoroshiro256**, a fast, all-purpose pseudo-random number generator: https://prng.di.unimi.it The PRNG will be seeded by the system's entropy store when possible, falling back to current time and system data (pid, uptime, etc). Inspiration for this was taken from libressl, but since our PRNG is not used for cryptographic purposes (and indeed currently only generates a unique temp file name that is written in a protected directory), this should be more than sufficient. Our implementation of xoroshiro256** was taken almost strictly from the original author's sources, but was tested against PractRand to ensure that there were no foolish mistranslations: ``` RNG_test using PractRand version 0.94 RNG = RNG_stdin64, seed = unknown test set = core, folding = standard (64 bit) rng=RNG_stdin64, seed=unknown length= 256 megabytes (2^28 bytes), time= 2.9 seconds no anomalies in 210 test result(s) rng=RNG_stdin64, seed=unknown length= 512 megabytes (2^29 bytes), time= 6.2 seconds no anomalies in 226 test result(s) rng=RNG_stdin64, seed=unknown length= 1 gigabyte (2^30 bytes), time= 12.7 seconds no anomalies in 243 test result(s) rng=RNG_stdin64, seed=unknown length= 2 gigabytes (2^31 bytes), time= 25.4 seconds no anomalies in 261 test result(s) rng=RNG_stdin64, seed=unknown length= 4 gigabytes (2^32 bytes), time= 50.6 seconds no anomalies in 277 test result(s) rng=RNG_stdin64, seed=unknown length= 8 gigabytes (2^33 bytes), time= 104 seconds no anomalies in 294 test result(s) ```

Colin Stolley 19ec5923 2022-02-07T09:29:40 push: Prepare pack before sending pack header. For large pushes, preparing the pack can take a while. Currently we send the pack header first, followed by preparing the pack and then finally sending the pack. Unfortunately github.com will terminate a git-receive-pack command over http if it is idle for more than 10 seconds. This is easily exceeded for a large push, and so the push is rejected with a Broken Pipe error. This patch moves the pack preparation ahead of sending the pack header, so that the timeout is avoided. prepare_pack() can be called multiple times but will only do the work once, so the original PREPARE_PACK call inside git_packbuilder_foreach() remains.
