"git rev-parse ':/substring'" did not consider the history leading
only to HEAD when looking for a commit with the given substring,
when the HEAD is detached. This has been fixed.
* wc/find-commit-with-pattern-on-detached-head:
sha1-name.c: for ":/", find detached HEAD commits
|
|
This patch broadens the set of commits matched by ":/<pattern>" to
include commits reachable from HEAD but not any named ref. This avoids
surprising behavior when working with a detached HEAD and trying to
refer to a commit that was recently created and only exists within the
detached state.
If multiple worktrees exist, only the current worktree's HEAD is
considered reachable. This is consistent with the existing behavior for
other per-worktree refs: e.g., bisect refs are considered reachable, but
only within the relevant worktree.

Commit 74ed43711fd (grep: enable recurse-submodules to work on <tree>
objects, 2016-12-16) taught 'tree_entry_interesting()' to be able to
match across submodule boundaries in the presence of wildcards. This is
done by performing literal matching up to the first wildcard and then
punting to the submodule itself to perform more accurate pattern
matching. Instead of introducing a new flag to request this behavior,
commit 74ed43711fd overloaded the already existing 'recursive' flag in
'struct pathspec' to request this behavior.
This leads to a bug where whenever any other caller has the 'recursive'
flag set as well as a pathspec with wildcards that all submodules will
be indicated as matches. One simple example of this is:
git init repo
cd repo
git init submodule
git -C submodule commit -m initial --allow-empty
touch "[bracket]"
git add "[bracket]"
git commit -m bracket
git add submodule
git commit -m submodule
git rev-list HEAD -- "[bracket]"
Fix this by introducing the new flag 'recurse_submodules' in 'struct
pathspec' and using this flag to determine if matches should be allowed
to cross submodule boundaries.
This fixes https://github.com/git-for-windows/git/issues/1371.

For commands that take revisions and pathspecs, magic
pathspecs like ":(exclude)foo" require the user to specify
a disambiguating "--", since they do not match a file in the
filesystem, like:
git grep foo -- :(exclude)bar
This makes them more annoying to use than they need to be.
We loosened the rules for wildcards in 28fcc0b71 (pathspec:
avoid the need of "--" when wildcard is used, 2015-05-02).
Let's do the same for pathspecs with long-form magic.
We already handle the short-forms ":/" and ":^" specially in
check_filename(), so we don't need to handle them here. And
in fact, we could do the same with long-form magic, parsing
out the actual filename and making sure it exists. But there
are a few reasons not to do it that way:
- the parsing gets much more complicated, and we'd want to
hand it off to the pathspec code. But that code isn't
ready to do this kind of speculative parsing (it's happy
to die() when it sees a syntactically invalid pathspec).
- not all pathspec magic maps to a filesystem path. E.g.,
:(attr) should be treated as a pathspec regardless of
what is in the filesystem
- we can be a bit looser with ":(" than with the
short-form ":/", because it is much less likely to have
a false positive. Whereas ":/" also means "search for a
commit with this regex".
Note that because the change is in verify_filename() and not
in its helper check_filename(), this doesn't affect the
verify_non_filename() case. I.e., if an item that matches
our new rule doesn't resolve as an object, we may fallback
to treating it as a pathspec (rather than complaining it
doesn't exist). But if it does resolve (e.g., as a file in
the index that starts with an open-paren), we won't then
complain that it's also a valid pathspec. This matches the
wildcard-exception behavior.
And of course in either case, one can always insert the "--"
to get more precise results.

We special-case "git log :/foo" to work when "foo" exists in
the working tree. But :^ (and its alias :!) do not get the
same treatment, requiring the user to supply a
disambiguating "--". Let's make them work without requiring
the user to type the "--".

The DWIM magic in check_filename() doesn't just recognize
":/". It actually makes sure that the file it points to
exists. t4208 checks only the case where the path is
present, not the opposite. Since the next patches will be
touching this area, let's add a test to make sure it
continues working.

When parse_pathspec() is called with no paths, the behavior could be
either return no paths, or return one path that is cwd. Some commands
do the former, some the latter. parse_pathspec() itself does not make
either the default and requires the caller to specify either flag if
it may run into this situation.
I've grep'd through all parse_pathspec() call sites. Some pass
neither, but those are guaranteed never pass empty path to
parse_pathspec(). There are two call sites that may pass empty path
and are fixed with this patch.

:/abc may mean two things:
- as a revision, it means the revision that has "abc" in commit
message.
- as a pathpec, it means "abc" from root.
Currently we see ":/abc" as a rev (most of the time), but never see it
as a pathspec even if "abc" exists and "git log :/abc" will gladly
take ":/abc" as rev even it's ambiguous. This patch makes it:
- ambiguous when "abc" exists on worktree
- a rev if abc does not exist on worktree
- a path if abc is not found in any commits (although better use
"--" to avoid ambiguation because searching through commit DAG is
expensive)
A plus from this patch is, because ":/" never matches anything as a
rev, it is never considered a valid rev and because root directory
always exists, ":/" is always unambiguously seen as a pathspec.
