* commit-graph: add format documentDerrick Stolee2018-04-021-0/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | Add document specifying the binary format for commit graphs. This format allows for: * New versions. * New hash functions and hash lengths. * Optional extensions. Basic header information is followed by a binary table of contents into "chunks" that include: * An ordered list of commit object IDs. * A 256-entry fanout into that list of OIDs. * A list of metadata for the commits. * A list of "large edges" to enable octopus merges. The format automatically includes two parent positions for every commit. This favors speed over space, since using only one position per commit would cause an extra level of indirection for every merge commit. (Octopus merges suffer from this indirection, but they are very rare.) Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* csum-file: refactor finalize_hashfile() methodDerrick Stolee2018-04-026-12/+14
| | | | | | | | | | | | | | If we want to use a hashfile on the temporary file for a lockfile, then we need finalize_hashfile() to fully write the trailing hash but also keep the file descriptor open. Do this by adding a new CSUM_HASH_IN_STREAM flag along with a functional change that checks this flag before writing the checksum to the stream. This differs from previous behavior since it would be written if either CSUM_CLOSE or CSUM_FSYNC is provided.

* csum-file: rename hashclose() to finalize_hashfile()Derrick Stolee2018-04-028-13/+13
| | | | | | | | | | | The hashclose() method behaves very differently depending on the flags parameter. In particular, the file descriptor is not always closed. Perform a simple rename of "hashclose()" to "finalize_hashfile()" in preparation for functional changes.

| * revision: drop --show-all optionJeff King2018-02-223-42/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was an undocumented debugging aid that does not seem to have come in handy in the past decade, judging from its lack of mentions on the mailing list. Let's drop it in the name of simplicity. This is morally a revert of 3131b71301 (Add "--show-all" revision walker flag for debugging, 2008-02-09), but note that I did leave in the mapping of UNINTERESTING to "^" in get_revision_mark(). I don't think this would be possible to trigger with the current code, but it's the only sensible marker. We'll skip the usual deprecation period because this was explicitly a debugging aid that was never documented.

| * commit: drop uses of get_cached_commit_buffer()Jeff King2018-02-222-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "--show-all" revision option shows UNINTERESTING commits. Some of these commits may be unparsed when we try to show them (since we may or may not need to walk their parents to fulfill the request). Commit 3131b71301 (Add "--show-all" revision walker flag for debugging, 2008-02-09) resolved this by just skipping pretty-printing for commits without their object contents cached, saying: Because we now end up listing commits we may not even have been parsed at all "show_log" and "show_commit" need to protect against commits that don't have a commit buffer entry. That was the easy fix to avoid the pretty-printer segfaulting, but: 1. It doesn't work for all formats. E.g., --oneline prints the oid for each such commit but not a trailing newline, leading to jumbled output. 2. It only affects some commits, depending on whether we happened to parse them or not (so if they were at the tip of an UNINTERESTING starting point, or if we happened to traverse over them, you'd see more data). 3. It unncessarily ties the decision to show the verbose header to whether the commit buffer was cached. That makes it harder to change the logic around caching (e.g., if we could traverse without actually loading the full commit objects). These days it's safe to feed such a commit to the pretty-print code. Since be5c9fb904 (logmsg_reencode: lazily load missing commit buffers, 2013-01-26), we'll load it on demand in such a case. So let's just always show the verbose headers. This does change the behavior of plumbing, but: a. The --show-all option was explicitly introduced as a debugging aid, and was never documented (and has rarely even been mentioned on the list by git devs). b. Avoiding the commits was already not deterministic due to (2) above. So the caller might have seen full headers for these commits anyway, and would need to be prepared for it.

The original implementation of the hash algorithm abstraction assumed we would do that using heap allocations, and added a context size element to struct git_hash_algo. However, most of the existing code uses stack allocations and conversion would needlessly complicate various parts of the code. Add a union for the purpose of allocating hash contexts on the stack and a typedef for ease of use. Use this union for defining the init, update, and final functions to avoid casts. Remove the ctxsz element for struct git_hash_algo, which is no longer very useful. This does mean that stack allocations will grow slightly as additional hash functions are added, but this should not be a significant problem, since we don't allocate many hash contexts. The improved usability and benefits from avoiding dynamic allocation outweigh this small downside.

All the details are still hidden away behind the `fnmatch(3)` wall because bringing the whole specification here may be too much.

Instead of just using the first line, use the pretty machinery to create the output. In addition to the easier to follow code, this makes the output more consistent with other commands that print the title of the commit, such as 'git commit --oneline' or 'git checkout', which both use 'pp_commit_easy()' with the CMIT_FMT_ONELINE modifier. It is a slight change of the output if the second line of the commit message is not a blank line, i.e. if the commit message is foo bar previously we would print "HEAD is now at 000000 foo", while after this change we print "HEAD is now at 000000 foo bar", same as 'git log --oneline' shows "000000 foo bar". So this does make the output more consistent with other commands, and 'reset' is a porcelain command, so nobody should be parsing the output in scripts. The current behaviour dates back to 0e5a7faa3a ("Make "git reset" a builtin.", 2007-09-11), so I assume (without digging into the old codebase too much) that the logic was implemented because there was no convenience function such as 'pp_commit_easy' that would do this already.
