2015-06-22verify-tag: share code with verify-commitbrian m. carlson
verify-tag was executing an entirely different codepath than verify-commit, except for the underlying verify_signed_buffer. Move much of the code from check_commit_signature to a generic check_signature function and adjust both codepaths to call it. Update verify-tag to explicitly output the signature text, as we now call verify_signed_buffer with strbufs to catch the output, which prevents it from being printed automatically.

2015-04-16Revert "merge: pass verbosity flag down to merge-recursive"Junio C Hamano
This reverts commit 2bf15a3330a26183adc8563dbeeacc11294b8a01, whose intention was good, but the verbosity levels used in merge-recursive turns out to be rather uneven. For example, a merge of two branches with conflicting submodule updates used to report CONFLICT: output with --quiet but no longer (which *is* desired), while the final "Automatic merge failed; fix conflicts and then commit" message is still shown even with --quiet (which *is* inconsistent). Originally reported by Bryan Turner; it is too early to declare what the concensus is, but it seems that we would need to level the verbosity levels used in merge strategy backends before we can go forward. In the meantime, we'd revert to the old behaviour until that happens. cf. $gmane/267245

2015-04-02merge: pass verbosity flag down to merge-recursiveJeff King
This makes "git merge --quiet" really quiet when we call into merge-recursive. Note that we can't just pass our flag down as-is; the two parts of the code use different scales. We center at "0" as normal for git-merge (with "--quiet" giving a negative value), but merge-recursive uses "2" as its center. This patch passes a negative value to merge-recursive rather than "1", though, as otherwise the user would have to use "-qqq" to squelch all messages (but the downside is that the user cannot distinguish between levels 0-2 if without resorting to the GIT_MERGE_VERBOSITY variable). We may want to review and renormalize the message severities in merge-recursive, but that does not have to happen now. This is at least in improvement in the sense that we are respecting "--quiet" at all. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-04-02push-to-deploy: allow pushing into an unborn branch and updating itJunio C Hamano
Setting receive.denycurrentbranch to updateinstead and pushing into the current branch, when the working tree and the index is truly clean, is supposed to reset the working tree and the index to match the tree of the pushed commit. This did not work when pushing into an unborn branch. The code that drives push-to-checkout hook needs no change, as the interface is defined so that hook can decide what to do when the push is coming to an unborn branch and take an appropriate action since the beginning.

2015-03-24report_path_error(): move to dir.cJunio C Hamano
The expected call sequence is for the caller to use match_pathspec() repeatedly on a set of pathspecs, accumulating the "hits" in a separate array, and then call this function to diagnose a pathspec that never matched anything, as that can indicate a typo from the command line, e.g. "git commit Maekfile". Many builtin commands use this function from builtin/ls-files.c, which is not a very healthy arrangement. ls-files might have been the first command to feel the need for such a helper, but the need is shared by everybody who uses the "match and then report" pattern. Move it to dir.c where match_pathspec() is defined. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-03-20repack: turn on "ref paranoia" when doing a destructive repackJeff King
If we are repacking with "-ad", we will drop any unreachable objects. Likewise, using "-Ad --unpack-unreachable=<time>" will drop any old, unreachable objects. In these cases, we want to make sure the reachability we compute with "--all" is complete. We can do this by passing GIT_REF_PARANOIA=1 in the environment to pack-objects. Note that "-Ad" is safe already, because it only loosens unreachable objects. It is up to "git prune" to avoid deleting them.

2015-03-20prune: turn on ref_paranoia flagJeff King
Prune should know about broken objects at the tips of refs, so that we can feed them to our traversal rather than ignoring them. It's better for us to abort the operation on the broken object than it is to start deleting objects with an incomplete view of the reachability namespace. Note that for missing objects, aborting is the best we can do. For a badly-named ref, we technically could use its sha1 as a reachability tip. However, the iteration code just feeds us a null sha1, so there would be a reasonable amount of code involved to pass down our wishes. It's not really worth trying to do better, because this is a case that should happen extremely rarely, and the message we provide: fatal: unable to parse object: refs/heads/bogus:name is probably enough to point the user in the right direction.

2015-03-19clone: initialize atexit cleanup handler earlierJeff King
If clone fails, we generally try to clean up any directories we've created. We do this by installing an atexit handler, so that we don't have to manually trigger cleanup. However, since we install this after touching the filesystem, any errors between our initial mkdir() and our atexit() call will result in us leaving a crufty directory around. We can fix this by moving our atexit() call earlier. It's OK to do it before the junk_work_tree variable is set, because remove_junk makes sure the variable is initialized. This means we "activate" the handler by assigning to the junk_work_tree variable, which we now bump down to just after we call mkdir(). We probably do not want to do it before, because a plausible reason for mkdir() to fail is EEXIST (i.e., we are racing with another "git init"), and we would not want to remove their work. OTOH, this is probably not that big a deal; we will allow cloning into an empty directory (and skip the mkdir), which is already racy (i.e., one clone may see the other's empty dir and start writing into it). Still, it does not hurt to err on the side of caution here. Note that writing into junk_work_tree and junk_git_dir after installing the handler is also technically racy, as we call our handler on an async signal. Depending on the platform, we could see a sheared write to the variables. Traditionally we have not worried about this, and indeed we already do this later in the function. If we want to address that, it can come as a separate topic. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-03-19grep: fix "--quiet" overwriting current outputWilhelm Schuermann
When grep is called with the --quiet option, the pager is initialized despite not being used. When the pager is "less", anything output by previous commands and not ended with a newline is overwritten: $ echo -n aaa; echo bbb aaabbb $ echo -n aaa; git grep -q foo; echo bbb bbb This can be worked around, for example, by making sure STDOUT is not a TTY or more directly by setting git's pager to "cat": $ echo -n aaa; git grep -q foo > /dev/null; echo bbb aaabbb $ echo -n aaa; PAGER=cat git grep -q foo; echo bbb aaabbb But prevent calling the pager in the first place, which would also save an unnecessary fork().
