Patrick Steinhardt cb1cb24c 2015-11-24T10:18:58 blame: use size_t for line counts in git_blame_hunk It is not unreasonable to have versioned files with a line count exceeding 2^16. Upon blaming such files we fail to correctly keep track of the lines as `git_blame_hunk` stores them in `uint16_t` fields. Fix this by converting the line fields of `git_blame_hunk` to `size_t`. Add test to verify behavior.
Edward Thomson 337b2b08 2015-11-30T20:53:54 Merge pull request #3508 from libgit2/cmn/tree-parse-speed Improvements to tree parsing speed
Patrick Steinhardt bbd2fa4e 2015-11-30T18:05:27 object: remove unused constant OBJECT_BASE_SIZE
Carlos Martín Nieto 95ae3520 2015-11-30T17:32:18 tree: ensure the entry filename fits in 16 bits Return an error in case the length is too big. Also take this opportunity to have a single allocating function for the size and overflow logic.
Carlos Martín Nieto a27f31d8 2015-11-30T04:49:31 Merge pull request #3513 from ethomson/merge_recursive Recursive Merge
Carlos Martín Nieto ee42bb0e 2015-11-28T19:18:29 tree: make path len uint16_t and avoid holes This reduces the size of the struct from 32 to 26 bytes, and leaves a single padding byte at the end of the struct (which comes from the zero-length array).
Carlos Martín Nieto 2580077f 2015-11-15T00:44:02 tree: calculate the filename length once We already know the size due to the `memchr()` so use that information instead of calling `strlen()` on it.
Carlos Martín Nieto ed970748 2015-11-14T23:50:06 tree: pool the entry memory allocations These are rather small allocations, so we end up spending a non-trivial amount of time asking the OS for memory. Since these entries are tied to the lifetime of their tree, we can give the tree a pool so we speed up the allocations.
Carlos Martín Nieto 7132150d 2015-11-14T23:46:21 tree: avoid advancing over the filename multiple times We've already looked at the filename with `memchr()` and then used `strlen()` to allocate the entry. We already know how much we have to advance to get to the object id, so add the filename length instead of looking at each byte again.
Edward Thomson 5b9c63c3 2015-11-20T19:01:42 recursive merge: add a recursion limit
Edward Thomson 78859c63 2015-11-20T17:33:49 merge: handle conflicts in recursive base building When building a recursive merge base, allow conflicts to occur. Use the file (with conflict markers) as the common ancestor. The user has already seen and dealt with this conflict by virtue of having a criss-cross merge. If they resolved this conflict identically in both branches, then there will be no conflict in the result. This is the best case scenario. If they did not resolve the conflict identically in the two branches, then we will generate a new conflict. If the user is simply using standard conflict output then the results will be fairly sensible. But if the user is using a mergetool or using diff3 output, then the common ancestor will be a conflict file (itself with diff3 output, haha!). This is quite terrible, but it matches git's behavior.
Edward Thomson 76ade3a0 2015-11-10T21:21:26 merge: use annotated commits for recursion Use annotated commits to act as our virtual bases, instead of regular commits, to avoid polluting the odb with virtual base commits and trees. Instead, build an annotated commit with an index and pointers to the commits that it was merged from.
Edward Thomson 7730fe8e 2015-11-09T13:01:48 merge: merge annotated commits instead of regular commits
Edward Thomson 3f2bb387 2015-10-28T11:00:55 merge: octopus merge common ancestors when >2 When there are more than two common ancestors, continue merging the virtual base with the additional common ancestors, effectively octopus merging a new virtual base.
Edward Thomson 1b82f7b6 2015-10-27T14:24:51 merge: compute octopus merge bases
Edward Thomson 75dee59c 2015-10-26T10:37:58 merge: build virtual base of multiple merge bases When the commits to merge have multiple common ancestors, build a "virtual" base tree by merging the common ancestors.
Edward Thomson fa78782f 2015-10-22T17:00:09 merge: rename `git_merge_tree_flags_t` -> `git_merge_flags_t`
Edward Thomson 25e84f95 2015-11-23T15:49:54 checkout: only consider nsecs when built that way When examining the working directory and determining whether it's up-to-date, only consider the nanoseconds in the index entry when built with `GIT_USE_NSEC`. This prevents us from believing that the working directory is always dirty when the index was originally written with a git client that uinderstands nsecs (like git 2.x).

Carlos Martín Nieto 69d14948 2015-11-17T13:21:18 Merge pull request #3511 from ethomson/racy_fixes_2 Racy fixes for writing new indexes
Edward Thomson 3eac1037 2015-11-16T23:31:19 settings: allow users to set PROGRAMDATA Allow users to set the `git_libgit2_opts` search path for the `GIT_CONFIG_LEVEL_PROGRAMDATA`. Convert `GIT_CONFIG_LEVEL_PROGRAMDATA` to `GIT_SYSDIR_PROGRAMDATA` for setting the configuration.
Edward Thomson 5f32c506 2015-11-16T18:06:52 racy: make git_index_read_index handle raciness Ensure that `git_index_read_index` clears the uptodate bit on files that it modifies. Further, do not propagate the cache from an on-disk index into another on-disk index. Although this should not be done, as `git_index_read_index` is used to bring an in-memory index into another index (that may or may not be on-disk), ensure that we do not accidentally bring in these bits when misused.
Edward Thomson 27bc41cf 2015-11-13T16:31:51 index: clear uptodate bit on save The uptodate bit should have a lifecycle of a single read->write on the index. Once the index is written, the files within it should be scanned for racy timestamps against the new index timestamp.
Edward Thomson d1101263 2015-11-13T15:32:48 index: don't detect raciness in uptodate entries Keep track of entries that we believe are up-to-date, because we added the index entries since the index was loaded. This prevents us from unnecessarily examining files that we wrote during the cleanup of racy entries (when we smudge racily clean files that have a timestamp newer than or equal to the index's timestamp when we read it). Without keeping track of this, we would examine every file that we just checked out for raciness, since all their timestamps would be newer than the index's timestamp.
Edward Thomson cb0ff012 2015-11-06T17:15:35 racy-git: do a single index->workdir diff When examining paths that are racily clean, do a single index->workdir diff over the entirety of the racily clean files, instead of a diff per file.

Carlos Martín Nieto 1411cb9e 2015-10-02T03:57:14 winhttp: use a custom user-agent if the user has set it We also keep the "git/1.0" prefix in order to maintain compatibility with hosters.
Carlos Martín Nieto 94bac76c 2015-10-02T03:46:34 http: use a custom user-agent if the user has set it We still prefix it with "git/1.0" since that's required in many situations, but we replace the area which mentions libgit2.
Edward Thomson 0a700ee3 2015-11-03T17:34:54 reflog: error when a directory is at reflog path When a non-empty directory exists and prevents the creation of a reflog, provide a more informative error message.
Edward Thomson b46c7ee5 2015-11-03T17:18:00 refs: complain when a directory exists at ref When a (non-empty) directory exists at the reference target location, complain with a more actionable error message.
Carlos Martín Nieto ad8509ef 2015-11-12T11:54:06 index: overwrite the path when inserting conflicts When we insert a conflict in a case-insensitive index, accept the new entry's path as the correct case instead of leaving the path we already had. This puts `git_index_conflict_add()` on the same level as `git_index_add()` in this respect.
Carlos Martín Nieto 16604d74 2015-11-11T00:36:15 index: correctly report which conflict stage has a wrong filemode When we're at offset 'i', we're dealing with the 'i+1' stage, since conflicts start at 1.
Carlos Martín Nieto 1c34b717 2015-11-08T05:10:18 Merge pull request #3498 from ethomson/windows_symlinks Diff: Honor `core.symlinks=false` and fake symlinks

Edward Thomson f4b02671 2015-11-04T16:17:51 submodule: reload HEAD/index after reading config Reload the HEAD and index data for a submodule after reading the configuration. The configuration may specify a `path`, so we must update HEAD and index data with that path in mind.

Stjepan Rajko f5f96a23 2015-10-09T10:41:06 Fix git_commit_summary to convert newlines to spaces even after whitespace. Collapse spaces around newlines for the summary.
Edward Thomson ec50b23a 2015-11-03T17:02:07 filebuf: detect directories in our way When creating a filebuf, detect a directory that exists in our target file location. This prevents a failure later, when we try to move the lock file to the destination.
Edward Thomson 6b0fc6ab 2015-11-03T09:43:18 diff: on win32, treat fake "symlinks" specially On platforms that lack `core.symlinks`, we should not go looking for symbolic links and `p_readlink` their target. Instead, we should examine the file's contents.
Carlos Martín Nieto 7fafde63 2015-10-13T11:25:41 stream: allow registering a user-provided TLS constructor This allows the application to use their own TLS stream, regardless of the capabilities of libgit2 itself.

Carlos Martín Nieto 3547b122 2015-10-30T21:36:51 filebuf: use an internal buffer This reduces the chances of a crash in the thread tests. This shouldn't affect general usage too much, since the main usage of these functions are to read into an empty buffer.
Carlos Martín Nieto eb597799 2015-10-29T21:12:37 filebuf: use a checksum to detect file changes Instead of relying on the size and timestamp, which can hide changes performed in the same second, hash the file content's when we care about detecting changes.

Vicent Marti d307a013 2015-10-27T22:17:32 reuc: Be smarter when inserting new REUC entries Inserting new REUC entries can quickly become pathological given that each insert unsorts the REUC vector, and both subsequent lookups *and* insertions will require sorting it again before being successful. To avoid this, we're switching to `git_vector_insert_sorted`: this keeps the REUC vector constantly sorted and lets us use the `on_dup` callback to skip an extra binary search on each insertion.

Carlos Martín Nieto dc2cf3eb 2015-10-22T18:35:43 Merge pull request #3480 from ethomson/nsecs Nanoseconds in the index: ignore for diffing
Edward Thomson c7b336b0 2015-10-22T10:29:51 xdiff: reference util.h in parent directory Although CMake will correctly configure include directories for us, some people may use their own build system, and we should reference `util.h` based on where it actually lives.
Edward Thomson 7499eae9 2015-10-22T09:30:41 diff: ignore nsecs when diffing Although our index contains the literal time present in the index, we do not read nanoseconds from disk, and thus we should not use them in any comparisons, lest we always think our working directory is dirty. Guard this behind a `GIT_USE_NSECS` for future improvement.

Carlos Martín Nieto 8321596a 2015-10-15T12:22:10 Merge pull request #3444 from ethomson/add_preserves_conflict_mode Preserve modes from a conflict in `git_index_insert`
Vicent Marti a0a1b19a 2015-10-14T19:31:54 odb: Prioritize alternate backends For most real use cases, repositories with alternates use them as main object storage. Checking the alternate for objects before the main repository should result in measurable speedups. Because of this, we're changing the sorting algorithm to prioritize alternates *in cases where two backends have the same priority*. This means that the pack backend for the alternate will be checked before the pack backend for the main repository *but* both of them will be checked before any loose backends.
Vicent Marti 43820f20 2015-10-14T19:24:07 odb: Be smarter when refreshing backends In the current implementation of ODB backends, each backend is tasked with refreshing itself after a failed lookup. This is standard Git behavior: we want to e.g. reload the packfiles on disk in case they have changed and that's the reason we can't find the object we're looking for. This behavior, however, becomes pathological in repositories where multiple alternates have been loaded. Given that each alternate counts as a separate backend, a miss in the main repository (which can potentially be very frequent in cases where object storage comes from the alternate) will result in refreshing all its packfiles before we move on to the alternate backend where the object will most likely be found. To fix this, the code in `odb.c` has been refactored as to perform the refresh of all the backends externally, once we've verified that the object is nowhere to be found. If the refresh is successful, we then perform the lookup sequentially through all the backends, skipping the ones that we know for sure weren't refreshed (because they have no refresh API). The on-disk pack backend has been adjusted accordingly: it no longer performs refreshes internally.
Carlos Martín Nieto 5ffdea6f 2015-10-14T16:49:01 revwalk: make commit list use 64 bits for time We moved the "main" parsing to use 64 bits for the timestamp, but the quick parsing for the revwalk did not. This means that for large timestamps we fail to parse the time and thus the walk. Move this parser to use 64 bits as well.

Arthur Schreiber d3b29fb9 2015-10-01T00:50:37 refdb and odb backends must provide `free` function As refdb and odb backends can be allocated by client code, libgit2 can’t know whether an alternative memory allocator was used, and thus should not try to call `git__free` on those objects. Instead, odb and refdb backend implementations must always provide their own `free` functions to ensure memory gets freed correctly.

Edward Thomson 21515f22 2015-09-29T15:49:16 index: also try conflict mode when inserting When we do not trust the on-disk mode, we use the mode of an existing index entry. This allows us to preserve executable bits on platforms that do not honor them on the filesystem. If there is no stage 0 index entry, also look at conflicts to attempt to answer this question: prefer the data from the 'ours' side, then the 'theirs' side before falling back to the common ancestor.
