c2b3b0d8	2022-01-21T19:38:13	commit_graph: use raw oid data The commit graph contains arrays of raw oid data, use a byte array to index into them.
9ffa33a1	2022-01-22T08:48:43	oid: introduce `git_oid_raw_cpy` Now that oids are type-aware, they use their type to understand how many bytes to copy. Some callers may need to copy the raw bytes of the object id. This is equivalent to a memcpy that is a little more semantic.
6d8c7cab	2022-01-21T19:37:53	oid: introduce `git_oid_raw_ncmp`
526e8869	2022-01-21T19:17:40	oid: `hashcmp` is now `raw_cmp` We will talk about "raw" oids as untyped blobs of data; use a name for the comparison function that is in keeping with that.
c569738c	2022-01-22T08:55:41	indexer: write raw id data Don't write the object id structure, write its raw oid data.
563751d1	2022-01-22T06:42:50	treecache: write the raw id not the object We explicitly want to write on the id data, not the beginning of the object data, which may contain other information in the future.
831e20ac	2022-01-22T06:39:38	oidmap: hash on the id, not the object We explicitly want to hash on the id data, not the beginning of the object data, which may contain other information in the future.
590ff981	2022-01-21T19:49:09	oid: don't assume the size of an oid Don't assume that a `git_oid` is a particular size; allocate `sizeof(git_oid)` instead.
ab042161	2022-01-18T08:12:18	tree: move git_oid into tree entry A tree entry previously pointed directly into the object id within the tree object itself; this is useful to avoid any unnecessary memory copy (and an unnecessary use of 40 bytes per tree entry) but difficult if we change the underlying `git_oid` object to not simply be a raw object id but have additional structure. This commit moves the `git_oid` directly into the tree entry; this simplifies the tree entry creation from user data. We now copy the `git_oid` into place when parsing.

33b1d3fd	2022-04-05T13:10:33	[midx] Fix an undefined behavior (left-shift signed overflow) There was a missing check to ensure that the `off64_t` (which is a signed value) didn't overflow when parsing it from the midx file. This shouldn't have huge repercusions since the parsed value is immediately validated afterwards, but then again, there is no such thing as "benign" undefined behavior. This change makes all the bitwise arithmetic happen with unsigned types and is only casted to `off64_t` until the very end. Thanks to Taotao Gu for finding and reporting this!

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.
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.
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.
a9a7967a	2022-03-22T22:16:57	fetch: support OID refspec without dst Support the ability to create a refspec that is a single object ID without a destination.
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.

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.
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.

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.
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.
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.
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.
3344fddc	2021-11-16T23:29:22	refactor: `tests` is now `tests/libgit2` Like we want to separate libgit2 and utility source code, we want to separate libgit2 and utility tests. Start by moving all the tests into libgit2.

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.
ef4ab298	2021-11-14T08:47:40	refactor: `src` is now `src/libgit2`
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.

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.
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.

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:

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.
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.
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.

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.

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) ```

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.

tree: move git_oid into tree entry A tree entry previously pointed directly into the object id within the tree object itself; this is useful to avoid any unnecessary memory copy (and an unnecessary use of 40 bytes per tree entry) but difficult if we change the underlying `git_oid` object to not simply be a raw object id but have additional structure. This commit moves the `git_oid` directly into the tree entry; this simplifies the tree entry creation from user data. We now copy the `git_oid` into place when parsing.

[midx] Fix an undefined behavior (left-shift signed overflow) There was a missing check to ensure that the `off64_t` (which is a signed value) didn't overflow when parsing it from the midx file. This shouldn't have huge repercusions since the parsed value is immediately validated afterwards, but then again, there is no such thing as "benign" undefined behavior. This change makes all the bitwise arithmetic happen with unsigned types and is only casted to `off64_t` until the very end. Thanks to Taotao Gu for finding and reporting this!

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.

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.

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.

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.

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.

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) ```

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.
