The "--git-path", "--git-common-dir", and "--shared-index-path" options of "git rev-parse" did not produce usable output.

"git ls-remote" and "git archive --remote" are designed to work without being in a directory under Git's control. However, recent updates revealed that we randomly look into a directory called .git/ without actually doing necessary set-up when working in a repository.

The command line options for ssh invocation needs to be tweaked for some implementations of SSH (e.g. PuTTY plink wants "-P <port>" while OpenSSH wants "-p <port>" to specify port to connect to), and the variant was guessed when GIT_SSH environment variable is used to specify it.

2017-02-17rev-parse: fix several options when running in a subdirectoryLibravatar Johannes Schindelin3-5/+5
In addition to making git_path() aware of certain file names that need to be handled differently e.g. when running in worktrees, the commit 557bd833bb (git_path(): be aware of file relocation in $GIT_DIR, 2014-11-30) also snuck in a new option for `git rev-parse`: `--git-path`. On the face of it, there is no obvious bug in that commit's diff: it faithfully calls git_path() on the argument and prints it out, i.e. `git rev-parse --git-path <filename>` has the same precise behavior as calling `git_path("<filename>")` in C. The problem lies deeper, much deeper. In hindsight (which is always unfair), implementing the .git/ directory discovery in `setup_git_directory()` by changing the working directory may have allowed us to avoid passing around a struct that contains information about the current repository, but it bought us many, many problems. In this case, when being called in a subdirectory, `git rev-parse` changes the working directory to the top-level directory before calling `git_path()`. In the new working directory, the result is correct. But in the working directory of the calling script, it is incorrect. Example: when calling `git rev-parse --git-path HEAD` in, say, the Documentation/ subdirectory of Git's own source code, the string `.git/HEAD` is printed. Side note: that bug is hidden when running in a subdirectory of a worktree that was added by the `git worktree` command: in that case, the (correct) absolute path of the `HEAD` file is printed. In the interest of time, this patch does not go the "correct" route to introduce a struct with repository information (and removing global state in the process), instead this patch chooses to detect when the command was called in a subdirectory and forces the result to be an absolute path. While at it, we are also fixing the output of --git-common-dir and --shared-index-path. Lastly, please note that we reuse the same strbuf for all of the relative_path() calls; this avoids frequent allocation (and duplicated code), and it does not risk memory leaks, for two reasons: 1) the cmd_rev_parse() function does not return anywhere between the use of the new strbuf instance and its final release, and 2) git-rev-parse is one of these "one-shot" programs in Git, i.e. it exits after running for a very short time, meaning that all allocated memory is released with the exit() call anyway.

2017-02-14grep: treat revs the same for --untracked as for --no-indexLibravatar Jeff King1-1/+1
git-grep has always disallowed grepping in a tree (as opposed to the working directory) with both --untracked and --no-index. But we traditionally did so by first collecting the revs, and then complaining when any were provided. The --no-index option recently learned to detect revs much earlier. This has two user-visible effects: - we don't bother to resolve revision names at all. So when there's a rev/path ambiguity, we always choose to treat it as a path. - likewise, when you do specify a revision without "--", the error you get is "no such path" and not "--untracked cannot be used with revs". The rationale for doing this with --no-index is that it is meant to be used outside a repository, and so parsing revs at all does not make sense. This patch gives --untracked the same treatment. While it _is_ meant to be used in a repository, it is explicitly about grepping the non-repository contents. Telling the user "we found a rev, but you are not allowed to use revs" is not really helpful compared to "we treated your argument as a path, and could not find it".

2017-02-14remote helpers: avoid blind fall-back to ".git" when setting GIT_DIRLibravatar Jonathan Nieder1-0/+9
To push from or fetch to the current repository, remote helpers need to know what repository that is. Accordingly, Git sets the GIT_DIR environment variable to the path to the current repository when invoking remote helpers. There is a special case it does not handle: "git ls-remote" and "git archive --remote" can be run to inspect a remote repository without being run from any local repository. GIT_DIR is not useful in this scenario: - if we are not in a repository, we don't need to set GIT_DIR to override an existing GIT_DIR value from the environment. If GIT_DIR is present then we would be in a repository if it were valid and would have called die() if it weren't. - not setting GIT_DIR may cause a helper to do the usual discovery walk to find the repository. But we know we're not in one, or we would have found it ourselves. So in the worst case it may expend a little extra effort to try to find a repository and fail (for example, remote-curl would do this to try to find repository-level configuration). So leave GIT_DIR unset in this case. This makes GIT_DIR easier to understand for remote helper authors and makes transport code less of a special case for repository discovery.

2017-02-14remote: avoid reading $GIT_DIR config in non-repoLibravatar Jeff King1-0/+9
The "git ls-remote" command can be run outside of a repository, but needs to look up configured remotes. The config code is smart enough to handle this case itself, but we also check the historical "branches" and "remotes" paths in $GIT_DIR. The git_path() function causes us to blindly look at ".git/remotes", even if we know we aren't in a git repository. For now, this is just an unlikely bug (you probably don't have such a file if you're not in a repository), but it will become more obvious once we merge b1ef400ee (setup_git_env: avoid blind fall-back to ".git", 2016-10-20): [now] $ git ls-remote fatal: No remote configured to list refs from. [with b1ef400ee] $ git ls-remote fatal: BUG: setup_git_env called without repository We can fix this by skipping these sources entirely when we're outside of a repository. The test is a little more complex than the demonstration above. Rather than detect the correct behavior by parsing the error message, we can actually set up a case where the remote name we give is a valid repository, but b1ef400ee would cause us to die in the configuration step. This test doesn't fail now, but it future-proofs us for the b1ef400ee change. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-02-14grep: do not diagnose misspelt revs with --no-indexLibravatar Jeff King1-0/+5

2017-02-14grep: avoid resolving revision names in --no-index caseLibravatar Jeff King1-0/+13
We disallow the use of revisions with --no-index, but we don't actually check and complain until well after we've parsed the revisions. This is the cause of a few problems: 1. We shouldn't be calling get_sha1() at all when we aren't in a repository, as it might access the ref or object databases. For now, this should generally just return failure, but eventually it will become a BUG(). 2. When there's a "--" disambiguator and you're outside a repository, we'll complain early with "unable to resolve revision". But we can give a much more specific error. 3. When there isn't a "--" disambiguator, we still do the normal rev/path checks. This is silly, as we know we cannot have any revs with --no-index. Everything we see must be a path. Outside of a repository this doesn't matter (since we know it won't resolve), but inside one, we may complain unnecessarily if a filename happens to also match a refname. This patch skips the get_sha1() call entirely in the no-index case, and behaves as if it failed (with the exception of giving a better error message).

2017-02-14grep: fix "--" rev/pathspec disambiguationLibravatar Jeff King1-0/+33
If we see "git grep pattern rev -- file" then we apply the usual rev/pathspec disambiguation rules: any "rev" before the "--" must be a revision, and we do not need to apply the verify_non_filename() check. But there are two bugs here: 1. We keep a seen_dashdash flag to handle this case, but we set it in the same left-to-right pass over the arguments in which we parse "rev". So when we see "rev", we do not yet know that there is a "--", and we mistakenly complain if there is a matching file. We can fix this by making a preliminary pass over the arguments to find the "--", and only then checking the rev arguments. 2. If we can't resolve "rev" but there isn't a dashdash, that's OK. We treat it like a path, and complain later if it doesn't exist. But if there _is_ a dashdash, then we know it must be a rev, and should treat it as such, complaining if it does not resolve. The current code instead ignores it and tries to treat it like a path. This patch fixes both bugs, and tries to comment the parsing flow a bit better. It adds tests that cover the two bugs, but also some related situations (which already worked, but this confirms that our fixes did not break anything).

2017-02-14grep: do not unnecessarily query repo for "--"Libravatar Jonathan Tan1-0/+15
When running a command of the form git grep --no-index pattern -- path in the absence of a Git repository, an error message will be printed: fatal: BUG: setup_git_env called without repository This is because "git grep" tries to interpret "--" as a rev. "git grep" has always tried to first interpret "--" as a rev for at least a few years, but this issue was upgraded from a pessimization to a bug in commit 59332d1 ("Resurrect "git grep --no-index"", 2010-02-06), which calls get_sha1 regardless of whether --no-index was specified. This bug appeared to be benign until commit b1ef400 ("setup_git_env: avoid blind fall-back to ".git"", 2016-10-20) when Git was taught to die in this situation. (This "git grep" bug appears to be one of the bugs that commit b1ef400 is meant to flush out.) Therefore, always interpret "--" as signaling the end of options, instead of trying to interpret it as a rev first.

2017-02-13gc: ignore old gc.log filesLibravatar David Turner1-0/+15
A server can end up in a state where there are lots of unreferenced loose objects (say, because many users are doing a bunch of rebasing and pushing their rebased branches). Running "git gc --auto" in this state would cause a gc.log file to be created, preventing future auto gcs, causing pack files to pile up. Since many git operations are O(n) in the number of pack files, this would lead to poor performance. Git should never get itself into a state where it refuses to do any maintenance, just because at some point some piece of the maintenance didn't make progress. Teach Git to ignore gc.log files which are older than (by default) one day old, which can be tweaked via the gc.logExpiry configuration variable. That way, these pack files will get cleaned up, if necessary, at least once per day. And operators who find a need for more-frequent gcs can adjust gc.logExpiry to meet their needs. There is also some cleanup: a successful manual gc, or a warning-free auto gc with an old log file, will remove any old gc.log files. It might still happen that manual intervention is required (e.g. because the repo is corrupt), but at the very least it won't be because Git is too dumb to try again.

In a9e38359e3 we taught git-p4 a way to re-encode path names from what was used in Perforce to UTF-8. This path re-encoding worked properly for "added" paths. "Removed" paths were not re-encoded and therefore different from the "added" paths. Consequently, these files were not removed in a git-p4 cloned Git repository because the path names did not match. Fix this by moving the re-encoding to a place that affects "added" and "removed" paths. Add a test to demonstrate the issue.

Now that the sequencer learned to process a "normal" interactive rebase, we use it. The original shell script is still used for "non-normal" interactive rebases, i.e. when --root or --preserve-merges was passed. Please note that the --root option (via the $squash_onto variable) needs special handling only for the very first command, hence it is still okay to use the helper upon continue/skip. Also please note that the --no-ff setting is volatile, i.e. when the interactive rebase is interrupted at any stage, there is no record of it. Therefore, we have to pass it from the shell script to the rebase--helper. Note: the test t3404 had to be adjusted because the the error messages produced by the sequencer comply with our current convention to start with a lower-case letter.

When using non-builtin protocols relying on a transport helper (such as http), push options are not propagated to the helper. The user could ask for push options and a push would seemingly succeed, but the push options would never be transported to the server, misleading the users expectation. Fix this by propagating the push options to the transport helper. This is only addressing the first issue of (1) the helper protocol does not propagate push-option (2) the http helper is not prepared to handle push-option Once we fix (2), the http transport helper can make use of push options as well, but that happens as a follow up. (1) is a bug fix, whereas (2) is a feature, which is why we only do (1) here. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-02-08tag: generate useful reflog messageLibravatar Cornelius Weig1-1/+17
When tags are created with `--create-reflog` or with the option `core.logAllRefUpdates` set to 'always', a reflog is created for them. So far, the description of reflog entries for tags was empty, making the reflog hard to understand. For example: 6e3a7b3 refs/tags/test@{0}: Now, a reflog message is generated when creating a tag, following the pattern "tag: tagging <short-sha1> (<description>)". If GIT_REFLOG_ACTION is set, the message becomes "$GIT_REFLOG_ACTION (<description>)" instead. If the tag references a commit object, the description is set to the subject line of the commit, followed by its commit date. For example: 6e3a7b3 refs/tags/test@{0}: tag: tagging 6e3a7b3398 (Git 2.12-rc0, 2017-02-03) If the tag points to a tree/blob/tag objects, the following static strings are taken as description: - "tree object" - "blob object" - "other tag object" Signed-off-by: Cornelius Weig <cornelius.weig@tngtech.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-02-08receive-pack: avoid duplicates between our refs and alternatesLibravatar Jeff King1-0/+38
We de-duplicate ".have" refs among themselves, but never check if they are duplicates of our local refs. It's not unreasonable that they would be if we are a "--shared" or "--reference" clone of a similar repository; we'd have all the same tags. We can handle this by inserting our local refs into the oidset, but obviously not suppressing duplicates (since the refnames are important). Note that this also switches the order in which we advertise refs, processing ours first and then any alternates. The order shouldn't matter (and arguably showing our refs first makes more sense).

2017-02-08diff: print line prefix for --name-only outputLibravatar Jeff King1-0/+48
If you run "git log --graph --name-only", the pathnames are not indented to go along with their matching commits (unlike all of the other diff formats). We need to output the line prefix for each item before writing it. The tests cover both --name-status and --name-only. The former actually gets this right already, because it builds on the --raw format functions. It's only --name-only which uses its own code (and this fix mirrors the code in diff_flush_raw()). Note that the tests don't follow our usual style of setting up the "expect" output inside the test block. This matches the surrounding style, but more importantly it is easier to read: we don't have to worry about embedded single-quotes, and the leading indentation is more obvious.

2017-02-07ref-filter: resurrect "strip" as a synonym to "lstrip"Libravatar Junio C Hamano1-0/+12
We forgot that "strip" was introduced at 0571979bd6 ("tag: do not show ambiguous tag names as "tags/foo"", 2016-01-25) as part of Git 2.8 (and 2.7.1) when we started calling this "lstrip" to make it easier to explain the new "rstrip" operation. We shouldn't have renamed the existing one; "lstrip" should have been a new synonym that means the same thing as "strip". Scripts in the wild are surely using the original form already.

2017-02-03completion: cache the path to the repositoryLibravatar SZEDER Gábor1-58/+103
After the previous changes in this series there are only a handful of $(__gitdir) command substitutions left in the completion script, but there is still a bit of room for improvements: 1. The command substitution involves the forking of a subshell, which has considerable overhead on some platforms. 2. There are a few cases, where this command substitution is executed more than once during a single completion, which means multiple subshells and possibly multiple 'git rev-parse' executions. __gitdir() is invoked twice while completing refs for e.g. 'git log', 'git rebase', 'gitk', or while completing remote refs for 'git fetch' or 'git push'. Both of these points can be addressed by using the __git_find_repo_path() helper function introduced in the previous commit: 1. __git_find_repo_path() stores the path to the repository in a variable instead of printing it, so the command substitution around the function can be avoided. Or rather: the command substitution should be avoided to make the new value of the variable set inside the function visible to the callers. (Yes, there is now a command substitution inside __git_find_repo_path() around each 'git rev-parse', but that's executed only if necessary, and only once per completion, see point 2. below.) 2. $__git_repo_path, the variable holding the path to the repository, is declared local in the toplevel completion functions __git_main() and __gitk_main(). Thus, once set, the path is visible in all completion functions, including all subsequent calls to __git_find_repo_path(), meaning that they wouldn't have to re-discover the path to the repository. So call __git_find_repo_path() and use $__git_repo_path instead of the $(__gitdir) command substitution to access paths in the .git directory. Turn tests checking __gitdir()'s repository discovery into tests of __git_find_repo_path() such that only the tested function changes but the expected results don't, ensuring that repo discovery keeps working as it did before. As __gitdir() is not used anymore in the completion script, mark it as deprecated and direct users' attention to __git_find_repo_path() and $__git_repo_path. Yet keep four __gitdir() tests to ensure that it handles success and failure of __git_find_repo_path() and that it still handles its optional remote argument, because users' custom completion scriptlets might depend on it.

2017-02-03completion: extract repository discovery from __gitdir()Libravatar SZEDER Gábor1-6/+16
To prepare for caching the path to the repository in the following commit, extract the repository discovering part of __gitdir() into the __git_find_repo_path() helper function, which stores the found path in the $__git_repo_path variable instead of printing it. Make __gitdir() a wrapper around this new function. Declare $__git_repo_path local in the toplevel completion functions __git_main() and __gitk_main() to ensure that it never leaks into the environment and influences subsequent completions (though this isn't necessary right now, as __gitdir() is still only executed in subshells, but will matter for the following commit). Adjust tests checking __gitdir() or any other completion function calling __gitdir() to perform those checks in a subshell to prevent $__git_repo_path from leaking into the test environment. Otherwise leave the tests unchanged to demonstrate that this change doesn't alter __gitdir()'s behavior.

2017-02-03completion: respect 'git -C <path>'Libravatar SZEDER Gábor1-0/+87
'git -C <path>' option(s) on the command line should be taken into account during completion, because - like '--git-dir=<path>', it can lead us to a different repository, - a few git commands executed in the completion script do care about in which directory they are executed, and - the command for which we are providing completion might care about in which directory it will be executed. However, unlike '--git-dir=<path>', the '-C <path>' option can be specified multiple times and their effect is cumulative, so we can't just store a single '<path>' in a variable. Nor can we simply concatenate a path from '-C <path1> -C <path2> ...', because e.g. (in an arguably pathological corner case) a relative path might be followed by an absolute path. Instead, store all '-C <path>' options word by word in the $__git_C_args array in the main git completion function, and pass this array, if present, to 'git rev-parse --absolute-git-dir' when discovering the repository in __gitdir(), and let it take care of multiple options, relative paths, absolute paths and everything. Also pass all '-C <path> options via the $__git_C_args array to those git executions which require a worktree and for which it matters from which directory they are executed from. There are only three such cases: - 'git diff-index' and 'git ls-files' in __git_ls_files_helper() used for git-aware filename completion, and - the 'git ls-tree' used for completing the 'ref:path' notation. The other git commands executed in the completion script don't need these '-C <path>' options, because __gitdir() already took those options into account. It would not hurt them, either, but let's not induce unnecessary code churn. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-02-03rev-parse: add '--absolute-git-dir' optionLibravatar SZEDER Gábor1-8/+9
The output of 'git rev-parse --git-dir' can be either a relative or an absolute path, depending on whether the current working directory is at the top of the worktree or the .git directory or not, or how the path to the repository is specified via the '--git-dir=<path>' option or the $GIT_DIR environment variable. And if that output is a relative path, then it is relative to the directory where any 'git -C <path>' options might have led us. This doesn't matter at all for regular scripts, because the git wrapper automatically takes care of changing directories according to the '-C <path>' options, and the scripts can then simply follow any path returned by 'git rev-parse --git-dir', even if it's a relative path. Our Bash completion script, however, is unique in that it must run directly in the user's interactive shell environment. This means that it's not executed through the git wrapper and would have to take care of any '-C <path> options on its own, and it can't just change directories as it pleases. Consequently, adding support for taking any '-C <path>' options on the command line into account during completion turned out to be considerably more difficult, error prone and required more subshells and git processes when it had to cope with a relative path to the .git directory. Help this rather special use case and teach 'git rev-parse' a new '--absolute-git-dir' option which always outputs a canonicalized absolute path to the .git directory, regardless of whether the path is discovered automatically or is specified via $GIT_DIR or 'git --git-dir=<path>'.
