2018-08-29convert "oidcmp() == 0" to oideq()Libravatar Jeff King1-3/+3
Using the more restrictive oideq() should, in the long run, give the compiler more opportunities to optimize these callsites. For now, this conversion should be a complete noop with respect to the generated code. The result is also perhaps a little more readable, as it avoids the "zero is equal" idiom. Since it's so prevalent in C, I think seasoned programmers tend not to even notice it anymore, but it can sometimes make for awkward double negations (e.g., we can drop a few !!oidcmp() instances here). This patch was generated almost entirely by the included coccinelle patch. This mechanical conversion should be completely safe, because we check explicitly for cases where oidcmp() is compared to 0, which is what oideq() is doing under the hood. Note that we don't have to catch "!oidcmp()" separately; coccinelle's standard isomorphisms make sure the two are treated equivalently. I say "almost" because I did hand-edit the coccinelle output to fix up a few style violations (it mostly keeps the original formatting, but sometimes unwraps long lines).

2018-08-14format-patch: allow --range-diff to apply to a lone-patchLibravatar Eric Sunshine1-0/+15
When submitting a revised version of a patch or series, it can be helpful (to reviewers) to include a summary of changes since the previous attempt in the form of a range-diff, typically in the cover letter. However, it is occasionally useful, despite making for a noisy read, to insert a range-diff into the commentary section of the lone patch of a 1-patch series. Therefore, extend "git format-patch --range-diff=<refspec>" to insert a range-diff into the commentary section of a lone patch rather than requiring a cover letter. Implementation note: Generating a range-diff for insertion into the commentary section of a patch which itself is currently being generated requires invoking the diffing machinery recursively. However, the machinery does not (presently) support this since it uses global state. Consequently, we need to take care to stash away the state of the in-progress operation while generating the range-diff, and restore it after.

When submitting a revised version of a patch or series, it can be helpful (to reviewers) to include a summary of changes since the previous attempt in the form of an interdiff, typically in the cover letter. However, it is occasionally useful, despite making for a noisy read, to insert an interdiff into the commentary section of the lone patch of a 1-patch series. Therefore, extend "git format-patch --interdiff=<prev>" to insert an interdiff into the commentary section of a lone patch rather than requiring a cover letter. The interdiff is indented to avoid confusing git-am and human readers into considering it part of the patch proper.

2018-07-23log-tree: show_log: make commentary block delimiting reusableLibravatar Eric Sunshine1-7/+16
In patches generated by git-format-patch, the area below the "---" line following the commit message and before the actual 'diff' can be used for commentary which the patch author wants to convey to readers of the patch itself but not include in the commit message proper. By default, the commentary area is empty, however, the --notes option causes it to be populated with notes associated with the commit. In the future, other options may be added which also insert content into the commentary section. To accommodate this, factor out the logic which delimits commentary blocks from the commit message so that it can be re-used for upcoming optional inserted content.

Sometimes it helps to list all available config vars so the user can search for something they want.

2018-05-21log_write_email_headers: use strbufsLibravatar Jeff King1-6/+10
When we write a MIME attachment, we write the mime headers into fixed-size buffers. These are likely to be big enough in practice, but technically the input could be arbitrarily large (e.g., if the caller provided a lot of content in the extra_headers string), in which case we'd quietly truncate it and generate bogus output. Let's convert these buffers to strbufs. The memory ownership here is a bit funny. The original fixed buffers were static, and we merely pass out pointers to them to be used by the caller (and in one case, we even just stuff our value into the opt->diffopt.stat_sep value). Ideally we'd actually pass back heap buffers, and the caller would be responsible for freeing them. This patch punts on that cleanup for now, and instead just marks the strbufs as static. That means we keep ownership in this function, making it not a complete leak. This also takes us one step closer to fixing it in the long term (since we can eventually use strbuf_detach() to hand ownership to the caller, once it's ready).

This should make these functions easier to find and cache.h less overwhelming to read. In particular, this moves: - read_object_file - oid_object_info - write_object_file As a result, most of the codebase needs to #include object-store.h. In this patch the #include is only added to files that would fail to compile otherwise. It would be better to #include wherever identifiers from the header are used.

2018-04-11treewide: rename tree to maybe_treeLibravatar Derrick Stolee1-3/+3
Using the commit-graph file to walk commit history removes the large cost of parsing commits during the walk. This exposes a performance issue: lookup_tree() takes a large portion of the computation time, even when Git never uses those trees. In anticipation of lazy-loading these trees, rename the 'tree' member of struct commit to 'maybe_tree'. This serves two purposes: it hints at the future role of possibly being NULL even if the commit has a valid tree, and it allows for unambiguous transformation from simple member access (i.e. commit->maybe_tree) to method access.

2018-02-22commit: drop uses of get_cached_commit_buffer()Libravatar Jeff King1-3/+0
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.

2017-11-22log: add option to choose which refs to decorateLibravatar Rafael Ascensão1-6/+18
When `log --decorate` is used, git will decorate commits with all available refs. While in most cases this may give the desired effect, under some conditions it can lead to excessively verbose output. Introduce two command line options, `--decorate-refs=<pattern>` and `--decorate-refs-exclude=<pattern>` to allow the user to select which refs are used in decoration. When "--decorate-refs=<pattern>" is given, only the refs that match the pattern are used in decoration. The refs that match the pattern when "--decorate-refs-exclude=<pattern>" is given, are never used in decoration. These options follow the same convention for mixing negative and positive patterns across the system, assuming that the inclusive default is to match all refs available. (1) if there is no positive pattern given, pretend as if an inclusive default positive pattern was given; (2) for each candidate, reject it if it matches no positive pattern, or if it matches any one of the negative patterns. The rules for what is considered a match are slightly different from the rules used elsewhere. Commands like `log --glob` assume a trailing '/*' when glob chars are not present in the pattern. This makes it difficult to specify a single ref. On the other hand, commands like `describe --match --all` allow specifying exact refs, but do not have the convenience of allowing "shorthand refs" like 'refs/heads' or 'heads' to refer to 'refs/heads/*'. The commands introduced in this patch consider a match if: (a) the pattern contains globs chars, and regular pattern matching returns a match. (b) the pattern does not contain glob chars, and ref '<pattern>' exists, or if ref exists under '<pattern>/' This allows both behaviours (allowing single refs and shorthand refs) yet remaining compatible with existent commands.

2017-10-21log: handle broken HEAD in decoration checkLibravatar Jeff King1-1/+1
The resolve_ref_unsafe() function may return NULL even with a REF_ISSYMREF flag if a symref points to a broken ref. As a result, it's possible for the decoration code's "is this branch the current HEAD" check to segfault when it passes the NULL to starts_with(). This is unlikely in practice, since we can only reach this code if we already resolved HEAD to a matching sha1 earlier. But it's possible if HEAD racily becomes broken, or if there's a transient filesystem error. We can fix this by returning early in the broken case, since NULL could not possibly match any of our branch names.
