Edward Thomson 8970acb7 2020-05-15T10:29:41 thread: don't use the global tlsdata for thread exit We want to store a pointer to emulate `pthread_exit` on Windows. Do this within the threading infrastructure so that it could potentially be re-used outside of the context of libgit2 itself.
Edward Thomson c40d2dc5 2020-05-15T10:09:51 thread: restore the git_thread_exit tests We were never properly testing git_thread_exit. Do so.
Edward Thomson 4853d94c 2020-05-14T10:36:35 global: separate global state from thread-local state Our "global initialization" has accumulated some debris over the years. It was previously responsible for both running the various global initializers (that set up various subsystems) _and_ setting up the "global state", which is actually the thread-local state for things like error reporting. Separate the thread local state out into "threadstate". Use the normal subsystem initialization functions that we already have to set it up. This makes both the global initialization system and the threadstate system simpler to reason about.
Edward Thomson bc3919ab 2020-07-11T12:14:26 global init: check error message buffer allocation Ensure that we can allocate the error message buffer. In keeping with our typical policiess, we allow (small) memory leaks in the case where we're out of memory.

Edward Thomson 6244791a 2020-10-11T11:28:55 Merge pull request #5594 from lhchavez/git-atomics Improve the support of atomics
lhchavez 03c0938f 2020-08-25T06:13:38 Avoid using atomics in pool.c Instead, globally initialize the system page size.
lhchavez cc1d7f5c 2020-08-01T17:47:20 Improve the support of atomics This change: * Starts using GCC's and clang's `__atomic_*` intrinsics instead of the `__sync_*` ones, since the former supercede the latter (and can be safely replaced by their equivalent `__atomic_*` version with the sequentially consistent model). * Makes `git_atomic64`'s value `volatile`. Otherwise, this will make ThreadSanitizer complain. * Adds ways to load the values from atomics. As it turns out, unsynchronized read are okay only in some architectures, but if we want to be correct (and make ThreadSanitizer happy), those loads should also be performed with the atomic builtins. * Fixes two ThreadSanitizer warnings, as a proof-of-concept that this works: - Avoid directly accessing `git_refcount`'s `owner` directly, and instead makes all callers go through the `GIT_REFCOUNT_*()` macros, which also use the atomic utilities. - Makes `pool_system_page_size()` race-free.

Patrick Steinhardt b254a585 2020-09-18T10:43:34 sysdir: fix formatting error message with NULL string When trying to the template dir, we pass in a `NULL` pointer for the filename. That's perfectly fine, but if we're failing to find the template directory then we'll creat an error message with the `NULL` pointer passed in. Fix the issue by setting different error messages based on whether the filename is given or not. This even makes sense, as we're not searching for a file in case we have no `name`, but for a directory. So the error would've been misleading anyway.

Edward Thomson 9bb61bad 2020-08-05T09:42:52 zstream: handle Z_BUF_ERROR appropriately in get_output_chunk Our processing loop in git_zstream_get_output_chunk does not handle `Z_BUF_ERROR` appropriately at the end of a compressed window. From the zlib manual, inflate will return: > Z_BUF_ERROR if no progress was possible or if there was not enough > room in the output buffer when Z_FINISH is used. Note that Z_BUF_ERROR > is not fatal, and inflate() can be called again with more input and > more output space to continue decompressing. In our loop, we were waiting until we got the expected size, then ensuring that we were at `Z_STREAM_END`. We are not guaranteed to be, since zlib may be in the `Z_BUF_ERROR` state where it has consumed a full window's worth of data, but it doesn't know that it's really at the end of the stream. There _could_ be more compressed data, but it doesn't _know_ that there's not until we make a subsequent call. We can change the loop to look for the end of stream instead of our expected size. This allows us to call inflate one last time when we are at the end of a window (and in the `Z_BUF_ERROR` state), allowing it to recognize the end of the stream, and move from the `Z_BUF_ERROR` state to the `Z_STREAM_END` state. If we do this, we need another exit condition: when `bytes == 0`, then no progress could be made and we should stop trying to inflate. This will be an error case, caught by the size and/or end-of-stream test.

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.

Edward Thomson 52ccbc5d 2020-08-03T09:52:30 Merge pull request #5582 from libgit2/pks-config-map-optimization config_entries: Avoid excessive map operations
Patrick Steinhardt f2400a9c 2020-07-13T20:56:08 config_entries: Avoid excessive map operations When appending config entries, we currently always first get the currently existing map entry and then afterwards update the map to contain the current config value. In the common scenario where keys aren't being overridden, this is the best we can do. But in case a key gets set multiple times, then we'll also perform these two map operations. In extreme cases, hashing the map keys will thus start to dominate performance. Let's optimize the pattern by using a separately allocated map entry. Currently, we always put the current list entry into the map and update it to get any overridden multivar. As these list entries are also used to iterate config entries, we cannot update them in-place in the map and are thus forced to always set the map to contain the new entry. But with a separately allocated map entry, we can now create one once per config key and insert it into the map. Whenever appending a new config value with the same key, we can now just update the map entry in-place instead of having to replace the map entry completely. This reduces calls to the hashing function by half and trades the improved runtime for one more allocation per unique config key. Given that the refactoring arguably improves code readability by splitting concerns of the `config_entry_list` type and not having to track it in two different structures, this alone would already be reason enough to take the trade. Given a pathological case of a gitconfig with 100.000 repeated keys and a section of length 10.000 characters, this reduces runtime by half from approximately 14 seconds to 7 seconds as expected.

Patrick Steinhardt 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.
Patrick Steinhardt 5434f9a3 2020-06-17T14:57:13 refs: remove function to read HEAD directly With the last user of `git_reference__read_head` gone, let's remove it as it's been reading references without consulting the refdb backends.
Patrick Steinhardt 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.
Patrick Steinhardt 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.
Patrick Steinhardt ac5fbe31 2020-06-17T14:43:27 branch: determine whether a branch is checked out via refdb We currently determine whether a branch is checked out via `git_repository_foreach_head`. As this function reads references directly from the disk, it breaks our refdb abstraction in case the repository uses a different reference backend implementation than the filesystem-based one. So let's use `git_repository_foreach_worktree` instead -- while it's less efficient, it is at least correct in all corner cases.
Patrick Steinhardt 7216b048 2020-06-17T14:23:15 refs: update HEAD references via refdb When renaming a reference, we need to iterate over every HEAD and potentially update it in case it is a symbolic reference pointing to the previous name of the renamed reference. Most importantly, this doesn't only include HEADs from the repo we're renaming the reference in, but we also need to iterate over HEADs from linked worktrees. In order to update the HEADs, we directly read them from the worktree's gitdir and thus assume that both repository and worktrees use the filesystem-based reference backend. But this breaks as soon as one got a repository with a different refdb and breaks our own abstractions. So let's instead update HEAD references via the refdb by first opening each worktree as a repository and then using the usual functions to read and update HEADs. This is a lot less efficient than the current code, but it's not like we can really help this: going via the refdb is mandatory.
Patrick Steinhardt 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.

Patrick Steinhardt 34987447 2020-06-30T10:13:26 refdb: avoid unlimited spinning in case of symref cycles To determine whether another reflog entry needs to be written for HEAD on a reference update, we need to see whether HEAD directly or indirectly points to the reference we're updating. The resolve logic is currently completely unbounded except an error occurs, which effectively means that we'd be spinning forever in case we have a symref loop in the repository refdb. Let's fix the issue by using `git_refdb_resolve` instead, which is always bounded.
Patrick Steinhardt b895547c 2020-06-30T09:35:21 refs: replace reimplementation of reference resolver The refs code currently has a second implementation that resolves references in order to find any final symbolic reference pointing to a nonexistent target branch. As we've just extended `git_refdb_resolve` to also return such references, let's use that one instead in order to reduce code duplication.
Patrick Steinhardt cf7dd05b 2020-06-30T13:26:05 refdb: return resolved symbolic refs pointing to nonexistent refs In some cases, resolving references requires us to also know about the final symbolic reference that's pointing to a nonexistent branch, e.g. in an empty repository where the main branch is yet unborn but HEAD already points to it. Right now, the resolving logic is thus split up into two, where one is the new refdb implementation and the second one is an ad-hoc implementation inside "refs.c". Let's extend `git_refdb_resolve` to also return such final dangling references pointing to nonexistent branches so we can deduplicate the resolving logic.
Patrick Steinhardt c54f40e4 2020-06-30T09:28:12 refs: move resolving of references into the refdb Resolving of symbolic references is currently implemented inside the "refs" layer. As a result, it's hard to call this function from low-level parts that only have a refdb available, but no repository, as the "refs" layer always operates on the repository-level. So let's move the function into the generic "refdb" implementation to lift this restriction.
