2017-03-23completion: support excluding full refsLibravatar SZEDER Gábor2-4/+35
Commit 49416ad22 (completion: support excluding refs, 2016-08-24) made possible to complete short refs with a '^' prefix. Extend the support to full refs to make completing '^refs/...' work. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-03-23completion: support completing fully qualified non-fast-forward refspecsLibravatar SZEDER Gábor2-1/+88
After 'git fetch <remote> <TAB>' our completion script offers refspecs that will fetch to a local branch with the same name as in the remote repository, e.g. 'master:master'. This also completes non-fast-forward refspecs, i.e. after a '+' prefix like '+master:master', and fully qualified refspecs, e.g. 'refs/heads/master:refs/heads/master'. However, it does not complete non-fast-forward fully qualified refspecs (or fully qualified refspecs following any other prefix, e.g. '--option=', though currently no git command supports such an option, but third party git commands might). These refspecs are listed by the __git_refs2() function, which is just a thin wrapper iterating over __git_refs()'s output, turning each listed ref into a refspec. Now, it's certainly possible to modify __git_refs2() and its callsite to pass an extra parameter containing only the ref part of the current word to be completed (to follow suit of the previous commit) to deal with prefixed fully qualified refspecs as well. Unfortunately, keeping the current behavior unchanged in the "no extra parameter" case brings in a bit of subtlety, which makes the resulting code ugly and compelled me to write a 8-line long comment in the proof of concept. Not good. However, since the callsite has to be modified for proper functioning anyway, we might as well leave __git_refs2() as is and introduce a new helper function without backwards compatibility concerns. Add the new function __git_complete_fetch_refspecs() that has all the necessary parameters to do the right thing in all cases mentioned above, including non-fast-forward fully qualified refspecs. This new function can also easier benefit from optimizations coming later in this patch series. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-03-23completion: support completing full refs after '--option=refs/<TAB>'Libravatar SZEDER Gábor2-7/+45
Completing full refs currently only works when the full ref stands on in its own on the command line, but doesn't work when the current word to be completed contains a prefix before the full ref, e.g. '--option=refs/<TAB>' or 'master..refs/bis<TAB>'. The reason is that __git_refs() looks at the current word to be completed ($cur) as a whole to decide whether it has to list full (if it starts with 'refs/') or short refs (otherwise). However, $cur also holds said '--option=' or 'master..' prefixes, which of course throw off this decision. Luckily, the default action is to list short refs, that's why completing short refs happens to work even after a 'master..<TAB>' prefix and similar cases. Pass only the ref part of the current word to be completed to __git_refs() as a new positional parameter, so it can make the right decision even if the whole current word contains some kind of a prefix. Make this new parameter the 4. positional parameter and leave the 3. as an ignored placeholder for now (it will be used later in this patch series).

2017-03-23completion: wrap __git_refs() for better option parsingLibravatar SZEDER Gábor2-35/+173
__git_refs() currently accepts two optional positional parameters: a remote and a flag for 'git checkout's tracking DWIMery. To fix a minor bug, and, more importantly, for faster refs completion, this series will add three more parameters: a prefix, the current word to be completed and a suffix, i.e. the options accepted by __gitcomp() & friends, and will change __git_refs() to list only refs matching that given current word and to add that given prefix and suffix to the listed refs. However, __git_refs() is the helper function that is most likely used in users' custom completion scriptlets for their own git commands, and we don't want to break those, so - we can't change __git_refs()'s default output format, i.e. we can't by default append a trailing space to every listed ref, meaning that the suffix parameter containing the default trailing space would have to be specified on every invocation, and - we can't change the position of existing positional parameters either, so there would have to be plenty of set-but-empty placeholder positional parameters all over the completion script. Furthermore, with five positional parameters it would be really hard to remember which position means what. To keep callsites simple, add the new wrapper function __git_complete_refs() around __git_refs(), which: - instead of positional parameters accepts real '--opt=val'-style options and with minimalistic option parsing translates them to __git_refs()'s and __gitcomp_nl()'s positional parameters, and - includes the '__gitcomp_nl "$(__git_refs ...)" ...' command substitution to make its behavior match its name and the behavior of other __git_complete_* functions, and to limit future changes in this series to __git_refs() and this new wrapper function. Call this wrapper function instead of __git_refs() wherever possible throughout the completion script, i.e. when __git_refs()'s output is fed to __gitcomp_nl() right away without further processing, which means all callsites except a single one in the __git_refs2() helper.

2017-02-03completion: cache the path to the repositoryLibravatar SZEDER Gábor2-75/+132
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 Gábor2-22/+42
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: don't guard git executions with __gitdir()Libravatar SZEDER Gábor1-21/+11
Three completion functions, namely __git_index_files(), __git_heads() and __git_tags(), first run __gitdir() and check that the path it outputs exists, i.e. that there is a git repository, and run a git command only if there is one. After the previous changes in this series there are no further uses of __gitdir()'s output in these functions besides those checks. And those checks are unnecessary, because we can just execute those git commands outside of a repository and let them error out. We don't perform such a check in other places either. Remove this check and the __gitdir() call from these functions, sparing the fork()+exec() overhead of the command substitution and the potential 'git rev-parse' execution.

2017-02-03completion: consolidate silencing errors from git commandsLibravatar SZEDER Gábor1-16/+12
Outputting error messages during completion is bad: they disrupt the command line, can't be deleted, and the user is forced to Ctrl-C and start over most of the time. We already silence stderr of many git commands in our Bash completion script, but there are still some in there that can spew error messages when something goes wrong. We could add the missing stderr redirections to all the remaining places, but instead let's leverage that git commands are now executed through the previously introduced __git() wrapper function, and redirect standard error to /dev/null only in that function. This way we need only one redirection to take care of errors from almost all git commands. Redirecting standard error of the __git() wrapper function thus became redundant, remove them. The exceptions, i.e. the repo-independent git executions and those in the __gitdir() function that don't go through __git() already have their standard error silenced.

2017-02-03completion: don't use __gitdir() for git commandsLibravatar SZEDER Gábor1-29/+31
Several completion functions contain the following pattern to run git commands respecting the path to the repository specified on the command line: git --git-dir="$(__gitdir)" <cmd> <options> This imposes the overhead of fork()ing a subshell for the command substitution and potentially fork()+exec()ing 'git rev-parse' inside __gitdir(). Now, if neither '--gitdir=<path>' nor '-C <path>' options are specified on the command line, then those git commands are perfectly capable to discover the repository on their own. If either one or both of those options are specified on the command line, then, again, the git commands could discover the repository, if we pass them all of those options from the command line. This means we don't have to run __gitdir() at all for git commands and can spare its fork()+exec() overhead. Use Bash parameter expansions to check the $__git_dir variable and $__git_C_args array and to assemble the appropriate '--git-dir=<path>' and '-C <path>' options if either one or both are present on the command line. These parameter expansions are, however, rather long, so instead of changing all git executions and make already long lines even longer, encapsulate running git with '--git-dir=<path> -C <path>' options into the new __git() wrapper function. Furthermore, this wrapper function will also enable us to silence error messages from git commands uniformly in one place in a later commit. There's one tricky case, though: in __git_refs() local refs are listed with 'git for-each-ref', where "local" is not necessarily the repository we are currently in, but it might mean a remote repository in the filesystem (e.g. listing refs for 'git fetch /some/other/repo <TAB>'). Use one-shot variable assignment to override $__git_dir with the path of the repository where the refs should come from. Although one-shot variable assignments in front of shell functions are to be avoided in our scripts in general, in the Bash completion script we can do that safely.

2017-02-03completion: respect 'git -C <path>'Libravatar SZEDER Gábor2-5/+101
'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 Gábor3-16/+31
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>'.

2017-02-03completion: fix completion after 'git -C <path>'Libravatar SZEDER Gábor2-5/+10
The main completion function finds the name of the git command by iterating through all the words on the command line in search for the first non-option-looking word. As it is not aware of 'git -C's mandatory path argument, if the '-C <path>' option is present, 'path' will be the first such word and it will be mistaken for a git command. This breaks completion in various ways: - If 'path' happens to match one of the commands supported by the completion script, then options of that command will be offered. - If 'path' doesn't match a supported command and doesn't contain any characters not allowed in Bash identifier names, then the completion script does basically nothing and Bash in turn falls back to filename completion for all subsequent words. - Otherwise, if 'path' does contain such an unallowed character, then it leads to a more or less ugly error message in the middle of the command line. The standard '/' directory separator is such a character, and it happens to trigger one of the uglier errors: $ git -C some/path <TAB>sh.exe": declare: `_git_some/path': not a valid identifier error: invalid key: alias.some/path Fix this by skipping 'git -C's mandatory path argument while iterating over the words on the command line. Extend the relevant test with this case and, while at it, with cases that needed similar treatment in the past ('--git-dir', '-c', '--work-tree' and '--namespace'). Additionally, silence the standard error of the 'declare' builtins looking for the completion function associated with the git command and of the 'git config' query for the aliased command. So if git ever learns a new option with a mandatory argument in the future, then, though the completion script will again misbehave, at least the command line will not be utterly disrupted by those error messages.

Don't offer anything right after these options, thus let Bash fall back to filename completion, because - the three options '--git-dir', '-C' and '--worktree' do actually require a path argument, and - we don't complete the required argument of '-c' and '--namespace', and in that case the "standard" behavior of our completion script is to not offer anything, but fall back to filename completion.

e832f5c09680 (completion: avoid ls-remote in certain scenarios, 2013-05-28) turned a 'git ls-remote <remote>' query into a 'git for-each-ref refs/remotes/<remote>/' to improve responsiveness of remote refs completion by avoiding potential network communication. However, it inadvertently made impossible to complete short refs from a remote given as a URL, e.g. 'git fetch git://server.com/repo.git <TAB>', because there is, of course, no such thing as 'refs/remotes/git://server.com/repo.git'. Since the previous commit we tell apart configured remotes, i.e. those that can have a hierarchy under 'refs/remotes/', from others that don't, including remotes given as URL, so we know when we can't use the faster 'git for-each-ref'-based approach. Resurrect the old, pre-e832f5c09680 'git ls-remote'-based code for the latter case to support listing short refs from remotes given as a URL. The code is slightly updated from the original to - take into account the path to the repository given on the command line (if any), and - omit 'ORIG_HEAD' from the query, as 'git ls-remote' will never list it anyway. When the remote given to __git_refs() doesn't exist, then it will be handled by this resurrected 'git ls-remote' query. This code path doesn't list 'HEAD' unconditionally, which has the nice side effect of fixing two more expected test failures.

If the remote given to __git_refs() happens to match both the name of a configured remote and the name of a directory in the current working directory, then that directory is assumed to be a git repository, and listing refs from that directory will be attempted. This is wrong, because in such a situation git commands (e.g. 'git fetch|pull|push <remote>' whom these refs will eventually be passed to) give precedence to the configured remote. Therefore, __git_refs() should list refs from the configured remote as well.

Don't use __gitdir() to check that the given remote is on the file system: basically it performs only a single if statement for us at the considerable cost of fork()ing a subshell for a command substitution.

Since this variable has a special role in the Bash completion script (it holds the word currently being completed) it influences the behavior of most completion functions and thus this leakage could interfere with subsequent tests. Although there are no such issues in the current tests, early versions of the new tests that will be added later in this series suffered because of this. It's better to play safe and declare $cur local in those test helper functions.

2017-02-03Merge branch 'cw/log-updates-for-all-refs-really'Libravatar Junio C Hamano15-30/+133
The "core.logAllRefUpdates" that used to be boolean has been enhanced to take 'always' as well, to record ref updates to refs other than the ones that are expected to be updated (i.e. branches, remote-tracking branches and notes). * cw/log-updates-for-all-refs-really: doc: add note about ignoring '--no-create-reflog' update-ref: add test cases for bare repository refs: add option core.logAllRefUpdates = always config: add markup to core.logAllRefUpdates doc
2017-02-03Merge branch 'pl/complete-diff-submodule-diff'Libravatar Junio C Hamano1-1/+1
The command line completion (in contrib/) learned that "git diff --submodule=" can take "diff" as a recently added option. * pl/complete-diff-submodule-diff: Completion: Add support for --submodule=diff
2017-02-03Merge branch 'rs/object-id'Libravatar Junio C Hamano7-10/+10
"uchar [40]" to "struct object_id" conversion continues. * rs/object-id: checkout: convert post_checkout_hook() to struct object_id use oidcpy() for copying hashes between instances of struct object_id use oid_to_hex_r() for converting struct object_id hashes to hex strings
2017-02-03Merge branch 'js/re-running-failed-tests'Libravatar Junio C Hamano1-0/+6
"make -C t failed" will now run only the tests that failed in the previous run. This is usable only when prove is not use, and gives a useless error message when run after "make clean", but otherwise is serviceable. * js/re-running-failed-tests: t/Makefile: add a rule to re-run previously-failed tests
2017-02-03Merge branch 'sb/submodule-update-initial-runs-custom-script'Libravatar Junio C Hamano2-1/+16
The user can specify a custom update method that is run when "submodule update" updates an already checked out submodule. This was ignored when checking the submodule out for the first time and we instead always just checked out the commit that is bound to the path in the superproject's index. * sb/submodule-update-initial-runs-custom-script: submodule update: run custom update script for initial populating as well
2017-02-03Merge branch 'sb/submodule-recursive-absorb'Libravatar Junio C Hamano4-41/+105
When a submodule "A", which has another submodule "B" nested within it, is "absorbed" into the top-level superproject, the inner submodule "B" used to be left in a strange state. The logic to adjust the .git pointers in these submodules has been corrected. * sb/submodule-recursive-absorb: submodule absorbing: fix worktree/gitdir pointers recursively for non-moves cache.h: expose the dying procedure for reading gitlinks setup: add gentle version of resolve_git_dir
2017-02-03Merge branch 'sb/unpack-trees-super-prefix'Libravatar Junio C Hamano5-676/+702
"git read-tree" and its underlying unpack_trees() machinery learned to report problematic paths prefixed with the --super-prefix option. * sb/unpack-trees-super-prefix: unpack-trees: support super-prefix option t1001: modernize style t1000: modernize style read-tree: use OPT_BOOL instead of OPT_SET_INT

2017-02-02Merge branch 'nd/log-graph-configurable-colors'Libravatar Junio C Hamano6-5/+97
Some people feel the default set of colors used by "git log --graph" rather limiting. A mechanism to customize the set of colors has been introduced. * nd/log-graph-configurable-colors: document behavior of empty color name color_parse_mem: allow empty color spec log --graph: customize the graph lines with config log.graphColors color.c: trim leading spaces in color_parse_mem() color.c: fix color_parse_mem() with value_len == 0

2017-02-02Merge branch 'bc/use-asciidoctor-opt'Libravatar Junio C Hamano5-13/+88
Asciidoctor, an alternative reimplementation of AsciiDoc, still needs some changes to work with documents meant to be formatted with AsciiDoc. "make USE_ASCIIDOCTOR=YesPlease" to use it out of the box to document our pages is getting closer to reality. * bc/use-asciidoctor-opt: Documentation: implement linkgit macro for Asciidoctor Makefile: add a knob to enable the use of Asciidoctor Documentation: move dblatex arguments into variable Documentation: add XSLT to fix DocBook for Texinfo Documentation: sort sources for gitman.texi Documentation: remove unneeded argument in cat-texi.perl Documentation: modernize cat-texi.perl Documentation: fix warning in cat-texi.perl

2017-02-02Merge branch 'js/mingw-hooks-with-exe-suffix'Libravatar Junio C Hamano1-1/+7
Names of the various hook scripts must be spelled exactly, but on Windows, an .exe binary must be named with .exe suffix; notice $GIT_DIR/hooks/<hookname>.exe as a valid <hookname> hook. * js/mingw-hooks-with-exe-suffix: mingw: allow hooks to be .exe files
2017-02-02Merge branch 'rs/receive-pack-cleanup'Libravatar Junio C Hamano1-2/+1
Code clean-up. * rs/receive-pack-cleanup: receive-pack: call string_list_clear() unconditionally

2017-02-02Merge branch 'hv/mingw-help-is-executable'Libravatar Junio C Hamano1-3/+18
"git help" enumerates executable files in $PATH; the implementation of "is this file executable?" on Windows has been optimized. * hv/mingw-help-is-executable: help: improve is_executable() on Windows
2017-02-02Merge branch 'gv/mingw-p4-mapuser'Libravatar Junio C Hamano1-1/+1
"git p4" did not work well with multiple git-p4.mapUser entries on Windows. * gv/mingw-p4-mapuser: git-p4: fix git-p4.mapUser on Windows

2017-02-02Merge branch 'js/unzip-in-usr-bin-workaround'Libravatar Junio C Hamano1-1/+3
Test tweak for FreeBSD where /usr/bin/unzip is unsuitable to run our tests but /usr/local/bin/unzip is usable. * js/unzip-in-usr-bin-workaround: test-lib: on FreeBSD, look for unzip(1) in /usr/local/bin/

Doc update. * cw/doc-sign-off: doc: clarify distinction between sign-off and pgp-signing
2017-02-02Merge branch 'js/status-pre-rebase-i'Libravatar Junio C Hamano2-4/+29
After starting "git rebase -i", which first opens the user's editor to edit the series of patches to apply, but before saving the contents of that file, "git status" failed to show the current state (i.e. you are in an interactive rebase session, but you have applied no steps yet) correctly. * js/status-pre-rebase-i: status: be prepared for not-yet-started interactive rebase
