1a2f9609	2021-01-05T06:24:26	commit-graph: Introduce `git_commit_graph_needs_refresh()` This change introduces a function that allows the caller to know whether the `commit-graph` file has not been modified since it was parsed. Part of: #5757
1f32ed25	2021-01-04T19:33:48	commit-graph: Support lookups of entries in a commit-graph This change introduces `git_commit_graph_entry_find()` and `git_commit_graph_entry_parent()`. These two functions allow a much faster lookup of commits by ID, since the ODB does not need to be consulted, the commit object does not need to be inflated, and the contents of the commit object do not need to be parsed. Part of: #5757
3fd57a75	2021-01-04T18:22:43	commit-graph: Introduce a parser for commit-graph files This change is the first in a series to add support for git's commit-graph. This should speed up commit graph traversals by avoiding object parsing and allowing some operations to terminate earlier. Part of: #5757

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/`.
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.)

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`.
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.

322c15ee	2020-08-01T18:24:41	Make the pack and mwindow implementations data-race-free This change fixes a packfile heap corruption that can happen when interacting with multiple packfiles concurrently across multiple threads. This is exacerbated by setting a lower mwindow open file limit. This change: * Renames most of the internal methods in pack.c to clearly indicate that they expect to be called with a certain lock held, making reasoning about the state of locks a bit easier. * Splits the `git_pack_file` lock in two: the one in `git_pack_file` only protects the `index_map`. The protection to `git_mwindow_file` is now in that struct. * Explicitly checks for freshness of the `git_pack_file` in `git_packfile_unpack_header`: this allows the mwindow implementation to close files whenever there is enough cache pressure, and `git_packfile_unpack_header` will reopen the packfile if needed. * After a call to `p_munmap()`, the `data` and `len` fields are poisoned with `NULL` to make use-after-frees more evident and crash rather than being open to the possibility of heap corruption. * Adds a test case to prevent this from regressing in the future. Fixes: #5591
f847fa7b	2020-02-16T02:00:56	midx: Support multi-pack-index files in odb_pack.c This change adds support for reading multi-pack-index files from the packfile odb backend. This also makes git_pack_file objects open their backing failes lazily in more scenarios, since the multi-pack-index can avoid having to open them in some cases (yay!). This change also refreshes the documentation found in src/odb_pack.c to match the updated code. Part of: #5399

74293ea0	2020-08-29T16:46:47	patch_parse: handle absence of "index" header for new/deleted cases This follows up on 11de594f85479e4804b07dc4f7b33cfe9212bea0 which added support for parsing patches without extended headers (the "index <hash>..<hash> <mode>" line); issue #5267. We now allow transition from "file mode" state to "path" state directly if there is no "index", which will happen for patches adding or deleting files as demonstrated in added test case.
471ed794	2020-07-13T10:05:04	clone: respect init.defaultBranch when empty When cloning an empty repository, we need to guess what the branch structure should be; instead of hardcoding `master`, use the `init.defaultBranch` setting it if it provided.
e411aae3	2020-07-13T08:47:15	repo: honor the init.defaultBranch setting As part of a push towards more inclusive language, git is reconsidering using "master" as the default branch name. As a first step, this setting will be configurable with the `init.defaultBranch` configuration option. Honor this during repository initialization. During initialization, we will create an initial branch: 1. Using the `initial_head` setting, if specified; 2. Using the `HEAD` configured in a template, if it exists; 3. Using the `init.defaultBranch` configuration option, if it is set; or 4. Using `master` in the absence of additional configuration.

ce4cb073	2020-07-12T18:19:21	tests: verify renaming branch really updates worktree HEAD In case where a branch is getting renamed, all HEADs of the main repository and of its worktrees that point to the old branch need to get updated to point to the new branch. We already do so and have a test for this, but the test only verifies that we're able to lookup the updated HEAD, not what it contains. Let's make the test more specific by verifying the updated HEAD also has the correct updated symbolic target.
65895410	2020-06-17T14:56:36	repository: retrieve worktree HEAD via refdb The function `git_repository_head_for_worktree` currently uses `git_reference__read_head` to directly read a given worktree's HEAD from the filesystem. This is broken in case the repository uses a different refdb implementation than the filesystem-based one, so let's instead open the worktree as a real repository and use `git_reference_lookup`. This also fixes the case where the worktree's HEAD is not a symref, but a detached HEAD, which would have resulted in an error previously.
d1f210fc	2020-06-17T15:09:49	repository: remove function to iterate over HEADs The function `git_repository_foreach_head` is broken, as it directly interacts with the on-disk representation of the reference database, thus assuming that no other refdb is used for the given repository. As this is an internal function only and all users have been replaced, let's remove this function.
2fcb4f28	2020-06-17T14:09:04	repository: introduce new function to iterate over all worktrees Given a Git repository, it's non-trivial to iterate over all worktrees that are associated with it, including the "main" repository. This commit adds a new internal function `git_repository_foreach_worktree` that does this for us.

eab2b044	2020-06-26T16:10:30	Review feedback * Change the default of the file limit to 0 (unlimited). * Changed the heuristic to close files to be the file that contains the least-recently-used window such that the window is the most-recently-used in the file, and the file does not have in-use windows. * Parameterized the filelimit test to check for a limit of 1 and 100 open windows.
9679df57	2020-02-08T20:47:24	mwindow: set limit on number of open files There are some cases in which repositories accrue a large number of packfiles. The existing mwindow limit applies only to the total size of mmap'd files, not on their number. This leads to a situation in which having lots of small packfiles could exhaust the allowed number of open files, particularly on macOS, where the default ulimit is very low (256). This change adds a new configuration parameter (GIT_OPT_SET_MWINDOW_FILE_LIMIT) that sets the maximum number of open packfiles, with a default of 128. This is low enough so that even macOS users should not hit it during normal use. Based on PR #5386, originally written by @josharian. Fixes: #2758

c6184f0c	2020-06-08T21:07:36	tree-wide: do not compile deprecated functions with hard deprecation When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h" header to be empty. As a result, no function declarations are made available to callers, but the implementations are still available to link against. This has the problem that function declarations also aren't visible to the implementations, meaning that the symbol's visibility will not be set up correctly. As a result, the resulting library may not expose those deprecated symbols at all on some platforms and thus cause linking errors. Fix the issue by conditionally compiling deprecated functions, only. While it becomes impossible to link against such a library in case one uses deprecated functions, distributors of libgit2 aren't expected to pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real" hard deprecation still makes sense in the context of CI to test we don't use deprecated symbols ourselves and in case a dependant uses libgit2 in a vendored way and knows it won't ever use any of the deprecated symbols anyway.

0d3ce2ac	2020-06-02T10:23:41	offer exact name matching with a `$` suffix When using `-s` to specify a particular test, it will do a prefix match. Thus, `-sapply::both::rename_a_to_b_to_c` will match both a test named `test_apply_both__rename_a_to_b_to_c` and a test that begins with that name, like `test_apply_both__rename_a_to_b_to_c_exact`. Permit a trailing `$` to `-s` syntax. This allows a user to specify `-sapply::both::rename_a_to_b_to_c$` to match _only_ the `test_apply_both__rename_a_to_b_to_c` function. We already filter to ensure that the given prefix matches the current test name. Also ensure that the length of the test name matches the length of the filter, sans trailing `$`.

8df4f519	2020-05-23T15:04:54	clar: copy files internally instead of /bin/cp clar has historically shelled out to `/bin/cp` to copy test fixtures into a sandbox. This has two deficiencies: 1. It's slower than simply opening the source and destination and copying them in a read/write loop. On my Mac, the `/bin/cp` based approach takes ~2:40 for a full test pass. Using a read/write loop to copy the files ourselves takes ~1:50. 2. It's noisy. Since the leak detector follows fork/exec, we'll end up running the leak detector on `/bin/cp`. This would be fine, except that the leak detector spams the console on startup and shutdown, so it adds a _lot_ of additional information to the test runs that is useless. By not forking and using this internal system, we see much less output.

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`.

Make the pack and mwindow implementations data-race-free This change fixes a packfile heap corruption that can happen when interacting with multiple packfiles concurrently across multiple threads. This is exacerbated by setting a lower mwindow open file limit. This change: * Renames most of the internal methods in pack.c to clearly indicate that they expect to be called with a certain lock held, making reasoning about the state of locks a bit easier. * Splits the `git_pack_file` lock in two: the one in `git_pack_file` only protects the `index_map`. The protection to `git_mwindow_file` is now in that struct. * Explicitly checks for freshness of the `git_pack_file` in `git_packfile_unpack_header`: this allows the mwindow implementation to close files whenever there is enough cache pressure, and `git_packfile_unpack_header` will reopen the packfile if needed. * After a call to `p_munmap()`, the `data` and `len` fields are poisoned with `NULL` to make use-after-frees more evident and crash rather than being open to the possibility of heap corruption. * Adds a test case to prevent this from regressing in the future.

As a first step, this setting will be configurable with the `init.defaultBranch` configuration option. Honor this during repository initialization. During initialization, we will create an initial branch: 1. Using the `initial_head` setting, if specified; 2. Using the `HEAD` configured in a template, if it exists; 3. Using the `init.defaultBranch` configuration option, if it is set; or 4. Using `master` in the absence of additional configuration.

tests: verify renaming branch really updates worktree HEAD In case where a branch is getting renamed, all HEADs of the main repository and of its worktrees that point to the old branch need to get updated to point to the new branch. We already do so and have a test for this, but the test only verifies that we're able to lookup the updated HEAD, not what it contains. Let's make the test more specific by verifying the updated HEAD also has the correct updated symbolic target.

repository: retrieve worktree HEAD via refdb The function `git_repository_head_for_worktree` currently uses `git_reference__read_head` to directly read a given worktree's HEAD from the filesystem. This is broken in case the repository uses a different refdb implementation than the filesystem-based one, so let's instead open the worktree as a real repository and use `git_reference_lookup`. This also fixes the case where the worktree's HEAD is not a symref, but a detached HEAD, which would have resulted in an error previously.

mwindow: set limit on number of open files There are some cases in which repositories accrue a large number of packfiles. The existing mwindow limit applies only to the total size of mmap'd files, not on their number. This leads to a situation in which having lots of small packfiles could exhaust the allowed number of open files, particularly on macOS, where the default ulimit is very low (256). This change adds a new configuration parameter (GIT_OPT_SET_MWINDOW_FILE_LIMIT) that sets the maximum number of open packfiles, with a default of 128. This is low enough so that even macOS users should not hit it during normal use. Based on PR #5386, originally written by @josharian. Fixes: #2758

tree-wide: do not compile deprecated functions with hard deprecation When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h" header to be empty. As a result, no function declarations are made available to callers, but the implementations are still available to link against. This has the problem that function declarations also aren't visible to the implementations, meaning that the symbol's visibility will not be set up correctly. As a result, the resulting library may not expose those deprecated symbols at all on some platforms and thus cause linking errors. Fix the issue by conditionally compiling deprecated functions, only. While it becomes impossible to link against such a library in case one uses deprecated functions, distributors of libgit2 aren't expected to pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real" hard deprecation still makes sense in the context of CI to test we don't use deprecated symbols ourselves and in case a dependant uses libgit2 in a vendored way and knows it won't ever use any of the deprecated symbols anyway.

offer exact name matching with a `$` suffix When using `-s` to specify a particular test, it will do a prefix match. Thus, `-sapply::both::rename_a_to_b_to_c` will match both a test named `test_apply_both__rename_a_to_b_to_c` and a test that begins with that name, like `test_apply_both__rename_a_to_b_to_c_exact`. Permit a trailing `$` to `-s` syntax. This allows a user to specify `-sapply::both::rename_a_to_b_to_c$` to match _only_ the `test_apply_both__rename_a_to_b_to_c` function. We already filter to ensure that the given prefix matches the current test name. Also ensure that the length of the test name matches the length of the filter, sans trailing `$`.

clar: remove files internally instead of /bin/rm Similar to how clar has used `/bin/cp` to copy files, it's used `/bin/rm` to remove them. This has similar deficiencies; meaning that leaks is noisy and it's slow. Move it to an internal function.

clar: copy files internally instead of /bin/cp clar has historically shelled out to `/bin/cp` to copy test fixtures into a sandbox. This has two deficiencies: 1. It's slower than simply opening the source and destination and copying them in a read/write loop. On my Mac, the `/bin/cp` based approach takes ~2:40 for a full test pass. Using a read/write loop to copy the files ourselves takes ~1:50. 2. It's noisy. Since the leak detector follows fork/exec, we'll end up running the leak detector on `/bin/cp`. This would be fine, except that the leak detector spams the console on startup and shutdown, so it adds a _lot_ of additional information to the test runs that is useless. By not forking and using this internal system, we see much less output.

strarray: we should `dispose` instead of `free` We _dispose_ the contents of objects; we _free_ objects (and their contents). Update `git_strarray_free` to be `git_strarray_dispose`. `git_strarray_free` remains as a deprecated proxy function.
