9703d26f	2020-06-29T12:22:27	tests: reflog: remove unused signature There's two tests that create a commit signature, but never make any use of it. Let's remove these to avoid any confusion.
9e4e25b1	2020-06-08T12:57:48	tests: refs: modernize coding style of testcase The coding style of the testcase refs::create::propagate_eexists is not really up-to-date. Convert it to use a more modern coding style.

51eff5a5	2020-05-29T13:13:19	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.
852c83ee	2020-01-15T13:31:21	refs: refuse to delete HEAD This requires adding a new symbolic ref to the testrepo fixture. Some of the existing tests attempt to delete HEAD, expecting a different failure. Introduce and use a non-HEAD symbolic ref instead. Adjust a few other tests as needed. Fixes #5357
97b8491b	2019-12-08T15:25:52	refs: rename git_reference__set_name to git_reference__realloc As git_reference__name will reallocate storage to account for longer names (it's actually allocator-dependent), it will cause all existing pointers to the old object to become dangling, as they now point to freed memory. Fix the issue by renaming to a more descriptive name, and pass a pointer to the actual reference that can safely be invalidated if the realloc succeeds.
bf2911d7	2019-11-02T07:30:32	Merge pull request #5275 from pks-t/pks/reflogs-with-newlines reflogs: fix behaviour around reflogs with newlines
7968e90f	2019-10-18T12:33:07	refdb_fs: properly parse corrupted reflogs In previous versions, libgit2 could be coerced into writing reflog messages with embedded newlines into the reflog by using `git_stash_save` with a message containing newlines. While the root cause is fixed now, it was noticed that upstream git is in fact able to read such corrupted reflog messages just fine. Make the reflog parser more lenient in order to just skip over malformatted reflog lines to bring us in line with git. This requires us to change an existing test that verified that we do indeed _fail_ to parse such logs.
d8233feb	2019-10-18T09:24:14	reflog: allow adding entries with newlines in their message Currently, the reflog disallows any entries that have a message with newlines, as that would effectively break the reflog format, which may contain a single line per entry, only. Upstream git behaves a bit differently, though, especially when considering stashes: instead of rejecting any reflog entry with newlines, git will simply replace newlines with spaces. E.g. executing 'git stash push -m "foo\nbar"' will create a reflog entry with "foo bar" as entry message. This commit adjusts our own logic to stop rejecting commit messages with newlines. Previously, this logic was part of `git_reflog_append`, only. There is a second place though where we add reflog entries, which is the serialization code in the filesystem refdb. As it didn't contain any sanity checks whatsoever, the refdb would have been perfectly happy to write malformatted reflog entries to the disk. This is being fixed with the same logic as for the reflog itself.
47531f47	2019-10-11T12:44:09	refs: unlock unmodified refs on transaction commit Refs which are locked in a transaction without an altered target, still should to be unlocked on `git_transaction_commit`. `git_transaction_free` also unlocks refs but the moment of calling of `git_transaction_free` cannot be controlled in all situations. Some binding libs call `git_transaction_free` on garbage collection or not at all if the application exits before and don't provide public access to `git_transaction_free`. It is better to release locks as soon as possible.
3335a034	2019-10-10T15:28:46	refs: fix locks getting forcibly removed The flag GIT_FILEBUF_FORCE currently does two things: 1. It will cause the filebuf to create non-existing leading directories for the file that is about to be written. 2. It will forcibly remove any pre-existing locks. While most call sites actually do want (1), they do not want to remove pre-existing locks, as that renders the locking mechanisms effectively useless. Introduce a new flag `GIT_FILEBUF_CREATE_LEADING_DIRS` to separate both behaviours cleanly from each other and convert callers to use it instead of `GIT_FILEBUF_FORCE` to have them honor locked files correctly. As this conversion removes all current users of `GIT_FILEBUF_FORCE`, this commit removes the flag altogether.
39d18fe6	2019-07-31T08:37:10	smart: use push_glob instead of manual filtering The code worked under the assumption that anything under `refs/tags` are tag objects, and all the rest would be peelable to a commit. As it is completely valid to have tags to blobs under a non `refs/tags` ref, this would cause failures when trying to peel a tag to a commit. Fix the broken filtering by switching to `git_revwalk_push_glob`, which already handles this case.
e54343a4	2019-06-29T09:17:32	fileops: rename to "futils.h" to match function signatures Our file utils functions all have a "futils" prefix, e.g. `git_futils_touch`. One would thus naturally guess that their definitions and implementation would live in files "futils.h" and "futils.c", respectively, but in fact they live in "fileops.h". Rename the files to match expectations.
51214b85	2019-04-26T10:15:49	refs: loosen restriction on wildcard "" refspecs In commit cd377f45c9 (refs: loosen restriction on wildcard "" refspecs, 2015-07-22) in git.git, the restrictions on wildcard "" refspecs has been loosened. While wildcards were previously only allowed if the component is a single "", this was changed to also accept other patterns as part of the component. We never adapted to that change and still reject any wildcard patterns that aren't a single "*" only. Update our tests to reflect the upstream change and adjust our own code accordingly.
0a25141e	2019-02-21T21:42:25	branch: add test for git_branch_lookup to accept GIT_BRANCH_ALL
bf013fc0	2019-02-14T13:30:33	branch: fix `branch_is_checked_out` with bare repos In a bare repository, HEAD usually points to the branch that is considered the "default" branch. As the current implementation for `git_branch_is_checked_out` only does a comparison of HEAD with the branch that is to be checked, it will say that the branch pointed to by HEAD in such a bare repo is checked out. Fix this by skipping the main repo's HEAD when it is bare.
788cd2d5	2019-02-14T13:49:35	branches: do not assert that the given ref is a branch Libraries should use assert(3P) only very scarcely. First, we usually shouldn't cause the caller of our library to abort in case where the assert fails. Second, if code is compiled with -DNDEBUG, then the assert will not be included at all. In our `git_branch_is_checked_out` function, we have an assert that verifies that the given reference parameter is non-NULL and in fact a branch. While the first check is fine, the second is not. E.g. when compiled with -DNDEBUG, we'd proceed and treat the given reference as a branch in all cases. Fix the issue by instead treating a non-branch reference as not being checked out. This is the obvious solution, as references other than branches cannot be directly checked out.
a0f87e16	2019-02-14T13:26:30	branches: add tests for `git_branch_is_checked_out` We currently do not have any tests at all for the `git_branch_is_checked_out` function. Add some basic ones.

9994cd3f	2018-06-25T11:56:52	treewide: remove use of C++ style comments C++ style comment ("//") are not specified by the ISO C90 standard and thus do not conform to it. While libgit2 aims to conform to C90, we did not enforce it until now, which is why quite a lot of these non-conforming comments have snuck into our codebase. Do a tree-wide conversion of all C++ style comments to the supported C style comments to allow us enforcing strict C90 compliance in a later commit.

b112b1e9	2017-10-06T11:24:11	refs: do not use peeled OID if peeling to a tag If a reference stored in a packed-refs file does not directly point to a commit, tree or blob, the packed-refs file will also will include a fully-peeled OID pointing to the first underlying object of that type. If we try to peel a reference to an object, we will use that peeled OID to speed up resolving the object. As a reference for an annotated tag does not directly point to a commit, tree or blob but instead to the tag object, the packed-refs file will have an accomodating fully-peeled OID pointing to the object referenced by that tag. When we use the fully-peeled OID pointing to the referenced object when peeling, we obviously cannot peel that to the tag anymore. Fix this issue by not using the fully-peeled OID whenever we want to peel to a tag. Note that this does not include the case where we want to resolve to _any_ object type. Existing code may make use from the fact that we resolve those to commit objects instead of tag objects, even though that behaviour is inconsistent between packed and loose references. Furthermore, some tests of ours make the assumption that we in fact resolve those references to a commit.
b6ed67c2	2017-05-10T12:54:14	tests: refs::crashes: create sandbox for creating symref The test `refs::crashes::double_free` operates on our in-source "testrepo.git" repository without creating a copy first. As the test will try to create a new symbolic reference, this will fail when we want to do a pure out-of-tree build with a read-only source tree. Fix the issue by creating a sandbox first.
6c23704d	2017-06-08T21:40:18	settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION` Initially, the setting has been solely used to enable the use of `fsync()` when creating objects. Since then, the use has been extended to also cover references and index files. As the option is not yet part of any release, we can still correct this by renaming the option to something more sensible, indicating not only correlation to objects. This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also move the variable from the object to repository source code.

f9793884	2016-10-28T14:32:01	branch: fix forced branch creation on HEAD of a bare repo The code correctly detects that forced creation of a branch on a nonbare repo should not be able to overwrite a branch which is the HEAD reference. But there's no reason to prevent this on a bare repo, and in fact, git allows this. I.e., git branch -f master new_sha works on a bare repo with HEAD set to master. This change fixes that problem, and updates tests so that, for this case, both the bare and nonbare cases are checked for correct behavior.

ac2fba0e	2015-09-16T15:07:27	git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.

If none do, we should abort. We currently ignore the error message from this operation, so let's not do that anymore. As part of the test we're writing, let's test for the expected behaviour if we cannot find a refspec which tells us what the remote-tracking branch for a remote would look like.

This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.

Fix the issue by renaming to a more descriptive name, and pass a pointer to the actual reference that can safely be invalidated if the realloc succeeds.

7968e90f

2019-10-18T12:33:07

refdb_fs: properly parse corrupted reflogs In previous versions, libgit2 could be coerced into writing reflog messages with embedded newlines into the reflog by using `git_stash_save` with a message containing newlines. While the root cause is fixed now, it was noticed that upstream git is in fact able to read such corrupted reflog messages just fine. Make the reflog parser more lenient in order to just skip over malformatted reflog lines to bring us in line with git. This requires us to change an existing test that verified that we do indeed _fail_ to parse such logs.

reflog: allow adding entries with newlines in their message Currently, the reflog disallows any entries that have a message with newlines, as that would effectively break the reflog format, which may contain a single line per entry, only. Upstream git behaves a bit differently, though, especially when considering stashes: instead of rejecting any reflog entry with newlines, git will simply replace newlines with spaces. E.g. executing 'git stash push -m "foo\nbar"' will create a reflog entry with "foo bar" as entry message. This commit adjusts our own logic to stop rejecting commit messages with newlines. Previously, this logic was part of `git_reflog_append`, only. There is a second place though where we add reflog entries, which is the serialization code in the filesystem refdb. As it didn't contain any sanity checks whatsoever, the refdb would have been perfectly happy to write malformatted reflog entries to the disk. This is being fixed with the same logic as for the reflog itself.

refs: unlock unmodified refs on transaction commit Refs which are locked in a transaction without an altered target, still should to be unlocked on `git_transaction_commit`. `git_transaction_free` also unlocks refs but the moment of calling of `git_transaction_free` cannot be controlled in all situations. Some binding libs call `git_transaction_free` on garbage collection or not at all if the application exits before and don't provide public access to `git_transaction_free`. It is better to release locks as soon as possible.

refs: fix locks getting forcibly removed The flag GIT_FILEBUF_FORCE currently does two things: 1. It will cause the filebuf to create non-existing leading directories for the file that is about to be written. 2. It will forcibly remove any pre-existing locks. While most call sites actually do want (1), they do not want to remove pre-existing locks, as that renders the locking mechanisms effectively useless. Introduce a new flag `GIT_FILEBUF_CREATE_LEADING_DIRS` to separate both behaviours cleanly from each other and convert callers to use it instead of `GIT_FILEBUF_FORCE` to have them honor locked files correctly. As this conversion removes all current users of `GIT_FILEBUF_FORCE`, this commit removes the flag altogether.

smart: use push_glob instead of manual filtering The code worked under the assumption that anything under `refs/tags` are tag objects, and all the rest would be peelable to a commit. As it is completely valid to have tags to blobs under a non `refs/tags` ref, this would cause failures when trying to peel a tag to a commit. Fix the broken filtering by switching to `git_revwalk_push_glob`, which already handles this case.

We never adapted to that change and still reject any wildcard patterns that aren't a single "*" only. Update our tests to reflect the upstream change and adjust our own code accordingly.

branch: fix `branch_is_checked_out` with bare repos In a bare repository, HEAD usually points to the branch that is considered the "default" branch. As the current implementation for `git_branch_is_checked_out` only does a comparison of HEAD with the branch that is to be checked, it will say that the branch pointed to by HEAD in such a bare repo is checked out. Fix this by skipping the main repo's HEAD when it is bare.

branches: do not assert that the given ref is a branch Libraries should use assert(3P) only very scarcely. First, we usually shouldn't cause the caller of our library to abort in case where the assert fails. Second, if code is compiled with -DNDEBUG, then the assert will not be included at all. In our `git_branch_is_checked_out` function, we have an assert that verifies that the given reference parameter is non-NULL and in fact a branch. While the first check is fine, the second is not. E.g. when compiled with -DNDEBUG, we'd proceed and treat the given reference as a branch in all cases. Fix the issue by instead treating a non-branch reference as not being checked out. This is the obvious solution, as references other than branches cannot be directly checked out.

refs: do not use peeled OID if peeling to a tag If a reference stored in a packed-refs file does not directly point to a commit, tree or blob, the packed-refs file will also will include a fully-peeled OID pointing to the first underlying object of that type. If we try to peel a reference to an object, we will use that peeled OID to speed up resolving the object. As a reference for an annotated tag does not directly point to a commit, tree or blob but instead to the tag object, the packed-refs file will have an accomodating fully-peeled OID pointing to the object referenced by that tag. When we use the fully-peeled OID pointing to the referenced object when peeling, we obviously cannot peel that to the tag anymore. Fix this issue by not using the fully-peeled OID whenever we want to peel to a tag. Note that this does not include the case where we want to resolve to _any_ object type. Existing code may make use from the fact that we resolve those to commit objects instead of tag objects, even though that behaviour is inconsistent between packed and loose references. Furthermore, some tests of ours make the assumption that we in fact resolve those references to a commit.

Since then, the use has been extended to also cover references and index files. As the option is not yet part of any release, we can still correct this by renaming the option to something more sensible, indicating not only correlation to objects. This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also move the variable from the object to repository source code.

But there's no reason to prevent this on a bare repo, and in fact, git allows this. I.e., git branch -f master new_sha works on a bare repo with HEAD set to master. This change fixes that problem, and updates tests so that, for this case, both the bare and nonbare cases are checked for correct behavior.

config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.

Introduce reference transactions A transaction allows you to lock multiple references and set up changes for them before applying the changes all at once (or as close as the backend supports). This can be used for replication purposes, or for making sure some operations run when the reference is locked and thus cannot be changed.

Refs: Extend unicode test for branch creation. This adds another assertion to ensure that the reference name inside the git_reference struct returned by `git_branch_create` is returned as precomposed if `core.precomposeunicode` is enabled.

Don't always test composed-insensitive lookups Only on a filesystem that is composed/decomposed insensitive, should be testing that a branch can be looked up by the opposite form and still work correctly.
