* Merge branch 'jc/check-ref-format-oor' into maintJunio C Hamano2017-11-15
|\ | | | | | | | | | | | | | | | | | | | | | | "git check-ref-format --branch @{-1}" bit a "BUG()" when run outside a repository for obvious reasons; clarify the documentation and make sure we do not even try to expand the at-mark magic in such a case, but still call the validation logic for branch names. * jc/check-ref-format-oor: check-ref-format doc: --branch validates and expands <branch> check-ref-format --branch: strip refs/heads/ using skip_prefix check-ref-format --branch: do not expand @{...} outside repository
| * check-ref-format --branch: strip refs/heads/ using skip_prefixJunio C Hamano2017-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The expansion returned from strbuf_check_branch_ref always starts with "refs/heads/" by construction, but there is nothing about its name or advertised API making that obvious. This command is used to process human-supplied input from the command line and is usually not the inner loop, so we can spare some cycles to be more defensive. Instead of hard-coding the offset strlen("refs/heads/") to skip, verify that the expansion actually starts with refs/heads/.

|\ \ | | | | | | | | | | | | | | | | | | | | | A broken access to object databases in recent update to "git grep --recurse-submodules" has been fixed. * bw/grep-recurse-submodules: grep: take the read-lock when adding a submodule
| * | grep: take the read-lock when adding a submoduleMartin Ågren2017-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With --recurse-submodules, we add each submodule that we encounter to the list of alternate object databases. With threading, our changes to the list are not protected against races. Indeed, ThreadSanitizer reports a race when we call `add_to_alternates_memory()` around the same time that another thread is reading in the list through `read_sha1_file()`. Take the grep read-lock while adding the submodule. The lock is used to serialize uses of non-thread-safe parts of Git's API, including `read_sha1_file()`.

In this case, the read_remote_branches() function will segfault passing the name to xstrdup(). This is hard to trigger in practice, since this function is used as a callback to for_each_ref(), which will skip broken refs in the first place (so it would have to be broken racily, or for us to see a transient filesystem error). If we see such a racy broken outcome let's treat it as "not a symref". This is exactly the same thing that would happen in the non-racy case (our function would not be called at all, as for_each_ref would skip the broken symref).

As that commit was built on top of 136c8c8b8f (color: check color.ui in git_default_config(), 2017-07-13) from the same series, we didn't need to touch tag's config parsing at all. However, since we reverted 136c8c8b8f, we now need to explicitly call git_color_default_config() to make this work. Let's do so, and also restore the test dropped in 0c88bf5050 (provide --color option for all ref-filter users, 2017-10-03). That commit swapped out our "color.ui=always" test for "--color" in preparation for "always" going away. But since it is here to stay, we should test both cases. Note that for-each-ref also lost its color.ui support as part of reverting 136c8c8b8f. But as a plumbing command, it should _not_ respect the color.ui config. Since it also gained a --color option in 0c88bf5050, that's the correct way to ask it for color. We'll continue to test that, and confirm that "color.ui" is not respected.

That commit was trying to address a bug caused by 4c7f1819b3 (make color.ui default to 'auto', 2013-06-10), in which plumbing like diff-tree defaulted to "auto" color, but did not respect a "color.ui" directive to disable it. But it also meant that we started respecting "color.ui" set to "always". This was a known problem, but 4c7f1819b3 argued that nobody ought to be doing that. However, that turned out to be wrong, and we got a number of bug reports related to "add -p" regressing in v2.14.2. Let's revert 136c8c8b8, fixing the regression to "add -p". This leaves the problem from 4c7f1819b3 unfixed, but: 1. It's a pretty obscure problem in the first place. I only noticed it while working on the color code, and we haven't got a single bug report or complaint about it. 2. We can make a more moderate fix on top by respecting "never" but not "always" for plumbing commands. This is just the minimal fix to go back to the working state we had before v2.14.2. Note that this isn't a pure revert. We now have a test in t3701 which shows off the "add -p" regression. This can be flipped to success.

The included changes were found using the following git grep: git grep '/ *2;' '*.c' Making this cleanup will prevent future review friction when a new binary search is contructed based on existing code.

For git-branch, you can do so with --color/--no-color. But for git-for-each-ref and git-tag, the other users of ref-filter, you have no option except to tweak the "color.ui" config setting. Let's give both of these commands the usual color command-line options. This is a bit more obvious as a method for overriding the config. And it also prepares us for the behavior of "always" changing (so that we are still left with a way of forcing color when our output goes to a non-terminal).

This is discussed further in 561598cfcf (read_pack_header: handle signed/unsigned comparison in read result, 2017-09-13). Each of these instances is actually fine in practice: - in get-tar-commit-id, the HEADERSIZE macro expands to a signed integer. If it were switched to an unsigned type (e.g., a size_t), then it would be a bug. - the other two callers check for a short read only after handling a negative return separately. This is a fine practice, but we'd prefer to model "!=" as a general rule. So all of these cases can be considered cleanups and not actual bugfixes.

Some of these commands may refresh the index and write out the result in an opportunistic way: if they can get the index lock, then they update the on-disk index with any updates they find. And if not, then their in-core refresh is lost and just has to be recomputed by the next caller. But taking the index lock may conflict with other operations in the repository. Especially ones that the user is doing themselves, which _aren't_ opportunistic. In other words, "git status" knows how to back off when somebody else is holding the lock, but other commands don't know that status would be happy to drop the lock if somebody else wanted it. There are a couple possible solutions: 1. Have some kind of "pseudo-lock" that allows other commands to tell status that they want the lock. This is likely to be complicated and error-prone to implement (and maybe even impossible with just dotlocks to work from, as it requires some inter-process communication). 2. Avoid background runs of commands like "git status" that want to do opportunistic updates, preferring instead plumbing like diff-files, etc. This is awkward for a couple of reasons. One is that "status --porcelain" reports a lot more about the repository state than is available from individual plumbing commands. And two is that we actually _do_ want to see the refreshed index. We just don't want to take a lock or write out the result. Whereas commands like diff-files expect us to refresh the index separately and write it to disk so that they can depend on the result. But that write is exactly what we're trying to avoid. 3. Ask "status" not to lock or write the index. This is easy to implement. The big downside is that any work done in refreshing the index for such a call is lost when the process exits. So a background process may end up re-hashing a changed file multiple times until the user runs a command that does an index refresh themselves. This patch implements the option 3. The idea (and the test) is largely stolen from a Git for Windows patch by Johannes Schindelin, 67e5ce7f63 (status: offer *not* to lock the index and update it, 2016-08-12). The twist here is that instead of making this an option to "git status", it becomes a "git" option and matching environment variable. The reason there is two-fold: 1. An environment variable is carried through to sub-processes. And whether an invocation is a background process or not should apply to the whole process tree. So you could do "git --no-optional-locks foo", and if "foo" is a script or alias that calls "status", you'll still get the effect. 2. There may be other programs that want the same treatment. I've punted here on finding more callers to convert, since "status" is the obvious one to call as a repeated background job. But "git diff"'s opportunistic refresh of the index may be a good candidate. The test is taken from 67e5ce7f63, and it's worth repeating Johannes's explanation: Note that the regression test added in this commit does not *really* verify that no index.lock file was written; that test is not possible in a portable way. Instead, we verify that .git/index is rewritten *only* when `git status` is run without `--no-optional-locks`.

It probably was made this way because "git branch -c A B" piggybacked its implementation on "git branch -m A B", This does not match the usual expectation. If I were sitting on a blue chair, and somebody comes and repaints it to red, I would accept ending up sitting on a chair that is now red (I am also OK to stand, instead, as there no longer is my favourite blue chair). But if somebody creates a new red chair, modelling it after the blue chair I am sitting on, I do not expect to be booted off of the blue chair and ending up on sitting on the new red one. Let's fix this before it hits 'next'. Those who want to create a new branch and switch to it can do "git checkout B" after doing a "git branch -c B", and if that operation is so useful and deserves a short-hand way to do so, perhaps extend "git checkout -b B" to copy configurations while creating the new branch B.

This is useful for e.g. copying a topic branch to a new version, e.g. work to work-2 after submitting the work topic to the list, while preserving all the tracking info and other configuration that goes with the branch, and unlike --move keeping the other already-submitted branch around for reference. Like --move, when the source branch is the currently checked out branch the HEAD is moved to the destination branch. In the case of --move we don't really have a choice (other than remaining on a detached HEAD) and in order to keep the functionality consistent, we are doing it in similar way for --copy too. The most common usage of this feature is expected to be moving to a new topic branch which is a copy of the current one, in that case moving to the target branch is what the user wants, and doesn't unexpectedly behave differently than --move would. One outstanding caveat of this implementation is that: git checkout maint && git checkout master && git branch -c topic && git checkout - Will check out 'maint' instead of 'master'. This is because the @{-N} feature (or its -1 shorthand "-") relies on HEAD reflogs created by the checkout command, so in this case we'll checkout maint instead of master, as the user might expect. What to do about that is left to a future change.

So if a tab character is placed between the option spec and the help text, it will be interpreted as part of the long option name or as part of the arg hint. If it is interpreted as part of the long option name, then rev-parse will produce what will be interpreted as multiple arguments on the command line. For example, the following option spec (note: there is a <tab> between "frotz" and "enable"): frotz enable frotzing will produce the following set expression when --frotz is used: set -- --frotz -- instead of this: set -- --frotz enable -- Mark t1502.2 as fixed.

So when we find the boundary white space marking the start of the help text, let's mark it with a nul character. Then when we search for flag characters starting from the beginning of the string we'll stop at the nul and won't enter the help text. Now, the following option spec: exclame this does something! will produce this 'set' expression when --exclame is specified: set -- --exclame -- instead of this one: set -- --exclame this does something -- Mark t1502.4 and t1502.5 as fixed.

Let's reimplement this with linear complexity (using a hash map to match the commits' subject lines) for the common case; Sadly, the fixup/squash feature's design neglected performance considerations, allowing arbitrary prefixes (read: `fixup! hell` will match the commit subject `hello world`), which means that we are stuck with quadratic performance in the worst case. The reimplemented logic also happens to fix a bug where commented-out lines (representing empty patches) were dropped by the previous code. While at it, clarify how the fixup/squash feature works in `git rebase -i`'s man page.
