4a0dceeb	2020-10-11T17:53:10	Make the Windows leak detection more robust This change: * Increases MY_ROW_LIMIT to 2M, since it has been failing in #5595's tests since it's _super_ close to the limit. * Calls `git_repository_free()` on a `git_repository` that was being leaked only in Windows. * Marks the global `git_repository` on `tests/repo/init.c` as `NULL` after being freed to make any accidental access more noisy. * Uses `cl_assert_equal_i()` in `test_trace_windows_stacktrace__leaks` to make the test failures more actionable. * Renames the globals in `tests/repo/init.c` so that they don't start with an underscore.

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.

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$` to match _only_ the `test_apply_both__rename_a_to_b_to_c` function. We already filter to ensure that the given prefix matches the current test name. Also ensure that the length of the test name matches the length of the filter, sans trailing `$`.

ee9e9163	2020-05-23T15:56:29	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.

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.

4dfcc50f	2020-04-01T15:16:18	merge: cache negative cache results for similarity metrics When computing renames, we cache the hash signatures for each of the potentially conflicting entries so that we do not need to repeatedly read the file and can at least halfway efficiently determine whether two files are similar enough to be deemed a rename. In order to make the hash signatures meaningful, we require at least four lines of data to be present, resulting in at least four different hashes that can be compared. Files that are deemed too small are not cached at all and will thus be repeatedly re-hashed, which is usually not a huge issue. The issue with above heuristic is in case a file does _not_ have at least four lines, where a line is anything separated by a consecutive run of "\n" or "\0" characters. For example "a\nb" is two lines, but "a\0\0b" is also just two lines. Taken to the extreme, a file that has megabytes of consecutive space- or NUL-only may also be deemed as too small and thus not get cached. As a result, we will repeatedly load its blob, calculate its hash signature just to finally throw it away as we notice it's not of any value. When you've got a comparitively big file that you compare against a big set of potentially renamed files, then the cost simply expodes. The issue can be trivially fixed by introducing negative cache entries. Whenever we determine that a given blob does not have a meaningful representation via a hash signature, we store this negative cache marker and will from then on not hash it again, but also ignore it as a potential rename target. This should help the "normal" case already where you have a lot of small files as rename candidates, but in the above scenario it's savings are extraordinarily high. To verify we do not hit the issue anymore with described solution, this commit adds a test that uses the exact same setup described above with one 50 megabyte blob of '\0' characters and 1000 other files that get renamed. Without the negative cache: $ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null real 11m48.377s user 11m11.576s sys 0m35.187s And with the negative cache: $ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null real 0m1.972s user 0m1.851s sys 0m0.118s So this represents a ~350-fold performance improvement, but it obviously depends on how many files you have and how big the blob is. The test number were chosen in a way that one will immediately notice as soon as the bug resurfaces.
5f47cb48	2020-03-26T14:16:41	patch: correctly handle mode changes for renames When generating a patch for a renamed file whose mode bits have changed in addition to the rename, then we currently fail to parse the generated patch. Furthermore, when generating a diff we output mode bits after the similarity metric, which is different to how upstream git handles it. Fix both issues by adding another state transition that allows similarity indices after mode changes and by printing mode changes before the similarity index.

fb7da154	2020-03-08T16:34:23	win32: clarify usage of path canonicalization funcs The path canonicalization functions on win32 are intended to canonicalize absolute paths; those with prefixes. In other words, things start with drive letters (`C:\`), share names (`\\server\share`), or other prefixes (`\\?\`). This function removes leading `..` that occur after the prefix but before the directory/file portion (eg, turning `C:\..\..\..\foo` into `C:\foo`). This translation is not appropriate for local paths.

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$` to match _only_ the `test_apply_both__rename_a_to_b_to_c` function. We already filter to ensure that the given prefix matches the current test name. Also ensure that the length of the test name matches the length of the filter, sans trailing `$`.

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.

merge: cache negative cache results for similarity metrics When computing renames, we cache the hash signatures for each of the potentially conflicting entries so that we do not need to repeatedly read the file and can at least halfway efficiently determine whether two files are similar enough to be deemed a rename. In order to make the hash signatures meaningful, we require at least four lines of data to be present, resulting in at least four different hashes that can be compared. Files that are deemed too small are not cached at all and will thus be repeatedly re-hashed, which is usually not a huge issue. The issue with above heuristic is in case a file does _not_ have at least four lines, where a line is anything separated by a consecutive run of "\n" or "\0" characters. For example "a\nb" is two lines, but "a\0\0b" is also just two lines. Taken to the extreme, a file that has megabytes of consecutive space- or NUL-only may also be deemed as too small and thus not get cached. As a result, we will repeatedly load its blob, calculate its hash signature just to finally throw it away as we notice it's not of any value. When you've got a comparitively big file that you compare against a big set of potentially renamed files, then the cost simply expodes. The issue can be trivially fixed by introducing negative cache entries. Whenever we determine that a given blob does not have a meaningful representation via a hash signature, we store this negative cache marker and will from then on not hash it again, but also ignore it as a potential rename target. This should help the "normal" case already where you have a lot of small files as rename candidates, but in the above scenario it's savings are extraordinarily high. To verify we do not hit the issue anymore with described solution, this commit adds a test that uses the exact same setup described above with one 50 megabyte blob of '\0' characters and 1000 other files that get renamed. Without the negative cache: $ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null real 11m48.377s user 11m11.576s sys 0m35.187s And with the negative cache: $ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null real 0m1.972s user 0m1.851s sys 0m0.118s So this represents a ~350-fold performance improvement, but it obviously depends on how many files you have and how big the blob is. The test number were chosen in a way that one will immediately notice as soon as the bug resurfaces.

patch: correctly handle mode changes for renames When generating a patch for a renamed file whose mode bits have changed in addition to the rename, then we currently fail to parse the generated patch. Furthermore, when generating a diff we output mode bits after the similarity metric, which is different to how upstream git handles it. Fix both issues by adding another state transition that allows similarity indices after mode changes and by printing mode changes before the similarity index.

Fix segfault when calling git_blame_buffer() This change makes sure that the hunk is not null before trying to dereference it. This avoids segfaults, especially when blaming against a modified buffer (i.e. the index). Fixes: #5443

win32: introduce relative path handling function Add a function that takes a (possibly) relative UTF-8 path and emits a UTF-16 path with forward slashes translated to backslashes. If the given path is, in fact, absolute, it will be translated to absolute path handling rules.

win32: clarify usage of path canonicalization funcs The path canonicalization functions on win32 are intended to canonicalize absolute paths; those with prefixes. In other words, things start with drive letters (`C:\`), share names (`\\server\share`), or other prefixes (`\\?\`). This function removes leading `..` that occur after the prefix but before the directory/file portion (eg, turning `C:\..\..\..\foo` into `C:\foo`). This translation is not appropriate for local paths.

tests: object: decrease number of concurrent cache accesses In our test case object::cache::fast_thread_rush, we're creating 100 concurrent threads opening a repository and reading objects from it. This test actually fails on ARM32 with an out-of-memory error, which isn't entirely unexpected. Work around the issue by halving the number of threads.

repository: handle format v1 Git has supported repository format version 1 for some time. This format is just like version 0, but it supports extensions. Implementations must reject extensions that they don't support. Add support for this format version and reject any extensions but extensions.noop, which is the only extension we currently support. While we're at it, also clean up an error message.
