2017-06-30grep: remove regflags from the public grep_opt APIÆvar Arnfjörð Bjarmason
Refactor calls to the grep machinery to always pass opt.ignore_case & opt.extended_regexp_option instead of setting the equivalent regflags bits. The bug fixed when making -i work with -P in commit 9e3cbc59d5 ("log: make --regexp-ignore-case work with --perl-regexp", 2017-05-20) was really just plastering over the code smell which this change fixes. The reason for adding the extensive commentary here is that I discovered some subtle complexity in implementing this that really should be called out explicitly to future readers. Before this change we'd rely on the difference between `extended_regexp_option` and `regflags` to serve as a membrane between our preliminary parsing of grep.extendedRegexp and grep.patternType, and what we decided to do internally. Now that those two are the same thing, it's necessary to unset `extended_regexp_option` just before we commit in cases where both of those config variables are set. See 84befcd0a4 ("grep: add a grep.patternType configuration setting", 2012-08-03) for the code and documentation related to that. The explanation of why the if/else branches in grep_commit_pattern_type() are ordered the way they are exists in that commit message, but I think it's worth calling this subtlety out explicitly with a comment for future readers. Even though grep_commit_pattern_type() is the only caller of grep_set_pattern_type_option() it's simpler to reset the extended_regexp_option flag in the latter, since 2/3 branches in the former would otherwise need to reset it, this way we can do it in one place.

2017-06-24wildmatch: remove unused wildopts parameterÆvar Arnfjörð Bjarmason
Remove the unused wildopts placeholder struct from being passed to all wildmatch() invocations, or rather remove all the boilerplate NULL parameters. This parameter was added back in commit 9b3497cab9 ("wildmatch: rename constants and update prototype", 2013-01-01) as a placeholder for future use. Over 4 years later nothing has made use of it, let's just remove it. It can be added in the future if we find some reason to start using such a parameter.

2017-06-19for_each_bisect_ref(): don't trim refnamesMichael Haggerty
`for_each_bisect_ref()` is called by `for_each_bad_bisect_ref()` with a term "bad". This used to make it call `for_each_ref_in_submodule()` with a prefix "refs/bisect/bad". But the latter is the name of the reference that is being sought, so the empty string was being passed to the callback as the trimmed refname. Moreover, this questionable practice was turned into an error by b9c8e7f2fb prefix_ref_iterator: don't trim too much, 2017-05-22 It makes more sense (and agrees better with the documentation of `--bisect`) for the callers to receive the full reference names. So * Add a new function, `for_each_fullref_in_submodule()`, to the refs API. This plugs a gap in the existing functionality, analogous to `for_each_fullref_in()` but accepting a `submodule` argument. * Change `for_each_bad_bisect_ref()` to call the new function rather than `for_each_ref_in_submodule()`. * Add a test.

2017-05-26log: add -P as a synonym for --perl-regexpÆvar Arnfjörð Bjarmason
Add a short -P option as a synonym for the longer --perl-regexp, for consistency with the options the corresponding grep invocations accept. This was intentionally omitted in commit 727b6fc3ed ("log --grep: accept --basic-regexp and --perl-regexp", 2012-10-03) for unspecified future use. Make it consistent with "grep" rather than to keep it open for future use, and to avoid the confusion of -P meaning different things for grep & log, as is the case with the -G option. As noted in the aforementioned commit the --basic-regexp option can't have a corresponding -G argument, as the log command already uses that for -G<regex>.

2017-05-24handle_revision_arg: record paths for pending objectsJeff King
If the revision parser sees an argument like tree:path, we parse it down to the correct blob (or tree), but throw away the "path" portion. Let's ask get_sha1_with_context() to record it, and pass it along in the pending array. This will let programs like git-diff which rely on the revision-parser show more accurate paths. Note that the implementation is a little tricky; we have to make sure we free oc.path in all code paths. For handle_dotdot(), we can piggy-back on the existing cleanup-wrapper pattern. The real work happens in handle_dotdot_1(), but the handle_dotdot() wrapper makes sure that the path is freed no matter how we exit the function (and for that reason we make sure that the object_context struct is zero'd, so if we fail to even get to the get_sha1_with_context() call, we just end up calling free(NULL)).

2017-05-24handle_revision_arg: record modes for "a..b" endpointsJeff King
The "a..b" revision syntax was designed to handle commits, so it doesn't bother to record any mode we find while traversing a "tree:path" endpoint. These days "git diff" can diff blobs using either "a:path..b:path" (with dots) or "a:path b:path" (without), but the two behave inconsistently, as the with-dots version fails to notice the mode. Let's teach the dot-dot range parser to record modes; it doesn't cost us anything, and it makes this case work.

2017-05-24handle_revision_arg: add handle_dotdot() helperJeff King
The handle_revision_arg function is rather long, and a big chunk of it is handling the range operators. Let's pull that out to a separate helper. While we're doing so, we can clean up a few of the rough edges that made the flow hard to follow: - instead of manually restoring *dotdot (that we overwrote with a NUL), do the real work in a sub-helper, which makes it clear that the munge/restore lines are a matched pair - eliminate a goto which wasn't actually used for control flow, but only to avoid duplicating a few lines (instead, those lines are pushed into another helper function) - use early returns instead of deep nesting - consistently name all variables for the left-hand side of the range as "a" (rather than "this" or "from") and the right-hand side as "b" (rather than "next", or using the unadorned "sha1" or "flags" from the main function).

2017-05-24handle_revision_arg: hoist ".." check out of range parsingJeff King
Since 003c84f6d (specifying ranges: we did not mean to make ".." an empty set, 2011-05-02), we treat the argument ".." specially. We detect it by noticing that both sides of the range are empty, and that this is a non-symmetric two-dot range. While correct, this makes the code overly complicated. We can just detect ".." up front before we try to do further parsing. This avoids having to de-munge the NUL from dotdot, and lets us eliminate an extra const array (which we needed only to do direct pointer comparisons). It also removes the one code path from the range-parsing conditional that requires us to return -1. That will make it simpler to pull the dotdot parsing out into its own function.

2017-05-24handle_revision_arg: stop using "dotdot" as a generic pointerJeff King
The handle_revision_arg() function has a "dotdot" variable that it uses to find a ".." or "..." in the argument. If we don't find one, we look for other marks, like "^!". But we just keep re-using the "dotdot" variable, which is confusing. Let's introduce a separate "mark" variable that can be used for these other marks. They still reuse the same variable, but at least the name is no longer actively misleading. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-05-24handle_revision_arg: simplify commit reference lookupsJeff King
The "dotdot" range parser avoids calling lookup_commit_reference() if we are directly fed two commits. But its casts are unnecessarily complex; that function will just return a commit we pass into it. Just calling the function all the time is much simpler, and doesn't do any significant extra work (the object is already parsed, and deref_tag() on a non-tag is a noop; we do incur one extra lookup_object() call, but that's fairly trivial).

2017-05-24handle_revision_arg: reset "dotdot" consistentlyJeff King
When we are parsing a range like "a..b", we write a temporary NUL over the first ".", so that we can access the names "a" and "b" as C strings. But our restoration of the original "." is done at inconsistent times, which can lead to confusing results. For most calls, we restore the "." after we resolve the names, but before we call verify_non_filename(). This means that when we later call add_pending_object(), the name for the left-hand "a" has been re-expanded to "a..b". You can see this with: git log --source a...b where "b" will be correctly marked with "b", but "a" will be marked with "a...b". Likewise with "a..b" (though you need to use --boundary to even see "a" at all in that case). To top off the confusion, when the REVARG_CANNOT_BE_FILENAME flag is set, we skip the non-filename check, and leave the NUL in place. That means we do report the correct name for "a" in the pending array. But some code paths try to show the whole "a...b" name in error messages, and these erroneously show only "a" instead of "a...b". E.g.: $ git cherry-pick HEAD:foo...HEAD:foo error: object d95f3ad14dee633a758d2e331151e950dd13e4ed is a blob, not a commit error: object d95f3ad14dee633a758d2e331151e950dd13e4ed is a blob, not a commit fatal: Invalid symmetric difference expression HEAD:foo (That last message should be "HEAD:foo...HEAD:foo"; I used cherry-pick because it passes the CANNOT_BE_FILENAME flag). As an interesting side note, cherry-pick actually looks at and re-resolves the arguments from the pending->name fields. So it would have been visibly broken by the first bug, but the effect was canceled out by the second one. This patch makes the whole function consistent by re-writing the NUL immediately after calling verify_non_filename(), and then restoring the "." as appropriate in some error-printing and early-return code paths.

2017-05-08Convert lookup_commit* to struct object_idbrian m. carlson
Convert lookup_commit, lookup_commit_or_die, lookup_commit_reference, and lookup_commit_reference_gently to take struct object_id arguments. Introduce a temporary in parse_object buffer in order to convert this function. This is required since in order to convert parse_object and parse_object_buffer, lookup_commit_reference_gently and lookup_commit_or_die would need to be converted. Not introducing a temporary would therefore require that lookup_commit_or_die take a struct object_id *, but lookup_commit would take unsigned char *, leaving a confusing and hard-to-use interface. parse_object_buffer will lose this temporary in a later patch.

2017-04-27timestamp_t: a new data type for timestampsJohannes Schindelin
Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.

2017-03-02interpret_branch_name: allow callers to restrict expansionsJeff King
The interpret_branch_name() function converts names like @{-1} and @{upstream} into branch names. The expanded ref names are not fully qualified, and may be outside of the refs/heads/ namespace (e.g., "@" expands to "HEAD", and "@{upstream}" is likely to be in "refs/remotes/"). This is OK for callers like dwim_ref() which are primarily interested in resolving the resulting name, no matter where it is. But callers like "git branch" treat the result as a branch name in refs/heads/. When we expand to a ref outside that namespace, the results are very confusing (e.g., "git branch @" tries to create refs/heads/HEAD, which is nonsense). Callers can't know from the returned string how the expansion happened (e.g., did the user really ask for a branch named "HEAD", or did we do a bogus expansion?). One fix would be to return some out-parameters describing the types of expansion that occurred. This has the benefit that the caller can generate precise error messages ("I understood @{upstream} to mean origin/master, but that is a remote tracking branch, so you cannot create it as a local name"). However, out-parameters make the function interface somewhat cumbersome. Instead, let's do the opposite: let the caller tell us which elements to expand. That's easier to pass in, and none of the callers give more precise error messages than "@{upstream} isn't a valid branch name" anyway (which should be sufficient). The strbuf_branchname() function needs a similar parameter, as most of the callers access interpret_branch_name() through it. We can break the callers down into two groups: 1. Callers that are happy with any kind of ref in the result. We pass "0" here, so they continue to work without restrictions. This includes merge_name(), the reflog handling in add_pending_object_with_path(), and substitute_branch_name(). This last is what powers dwim_ref(). 2. Callers that have funny corner cases (mostly in git-branch and git-checkout). These need to make use of the new parameter, but I've left them as "0" in this patch, and will address them individually in follow-on patches.

"git log rev^..rev" is an often-used revision range specification to show what was done on a side branch merged at rev. This has gained a short-hand "rev^-1". In general "rev^-$n" is the same as "^rev^$n rev", i.e. what has happened on other branches while the history leading to nth parent was looking the other way. * vn/revision-shorthand-for-side-branch-log: revision: new rev^-n shorthand for rev^n..rev
2016-09-27revision: new rev^-n shorthand for rev^n..revVegard Nossum
"git log rev^..rev" is commonly used to show all work done on and merged from a side branch. This patch introduces a shorthand "rev^-" for this and additionally allows "rev^-$n" to mean "reachable from rev, excluding what is reachable from the nth parent of rev". For example, for a two-parent merge, you can use rev^-2 to get the set of commits which were made to the main branch while the topic branch was prepared.

When "git rebase" tries to compare set of changes on the updated upstream and our own branch, it computes patch-id for all of these changes and attempts to find matches. This has been optimized by lazily computing the full patch-id (which is expensive) to be compared only for changes that touch the same set of paths. * kw/patch-ids-optim: rebase: avoid computing unnecessary patch IDs patch-ids: add flag to create the diff patch id using header only data patch-ids: replace the seen indicator with a commit pointer patch-ids: stop using a hand-rolled hashmap implementation
