# Be careful when updating this list:
#
# (1) The build tree may have build artifact from different branch, or
# the user's $PATH may have a random executable that may begin
# with "git-check" that are not part of the subcommands this build
# will ship, e.g. "check-ignore". The tests for completion for
# subcommand names tests how "check" is expanded; we limit the
# possible candidates to "checkout" and "check-attr" to make sure
# "check-attr", which is known by the filter function as a
# subcommand to be thrown out, while excluding other random files
# that happen to begin with "check" to avoid letting them get in
# the way.
#
# (2) A test makes sure that common subcommands are included in the
# completion for "git <TAB>", and a plumbing is excluded. "add",
# "filter-branch" and "ls-files" are listed for this.

completion: cache the path to the repository 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.

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.

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.

completion: respect 'git -C <path>' '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.

completion: cache the path to the repository 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.

completion: respect 'git -C <path>' '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.

completion: cache the path to the repository 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.

completion: cache the path to the repository 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.

completion: wrap __git_refs() for better option parsing __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.

completion: support completing fully qualified non-fast-forward refspecs 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>

completion: fix completion after 'git --option <TAB>' The bash completion doesn't work when certain options to git itself are specified, e.g. 'git --no-pager <TAB>' errors out with error: invalid key: alias.--no-pager The main _git() completion function finds out the git command name by looping through all the words on the command line and searching for the first word that is not a known option for the git command. Unfortunately the list of known git options was not updated in a long time, and newer options are not skipped but mistaken for a git command. Such a misrecognized "command" is then passed to __git_aliased_command(), which in turn passes it to a 'git config' query, hence the error. Currently the following options are misrecognized for a git command: -c --no-pager --exec-path --html-path --man-path --info-path --no-replace-objects --work-tree= --namespace= To fix this we could just update the list of options to be skipped, but the same issue will likely arise, if the git command learns a new option in the future. Therefore, to make it more future proof against new options, this patch changes that loop to skip all option-looking words, i.e. words starting with a dash. We also have to handle the '-c' option specially, because it takes a configutation parameter in a separate word, which must be skipped, too.

completion: fix completion after 'git -C <path>' 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.

completion: fix completion after 'git --option <TAB>' The bash completion doesn't work when certain options to git itself are specified, e.g. 'git --no-pager <TAB>' errors out with error: invalid key: alias.--no-pager The main _git() completion function finds out the git command name by looping through all the words on the command line and searching for the first word that is not a known option for the git command. Unfortunately the list of known git options was not updated in a long time, and newer options are not skipped but mistaken for a git command. Such a misrecognized "command" is then passed to __git_aliased_command(), which in turn passes it to a 'git config' query, hence the error. Currently the following options are misrecognized for a git command: -c --no-pager --exec-path --html-path --man-path --info-path --no-replace-objects --work-tree= --namespace= To fix this we could just update the list of options to be skipped, but the same issue will likely arise, if the git command learns a new option in the future. Therefore, to make it more future proof against new options, this patch changes that loop to skip all option-looking words, i.e. words starting with a dash. We also have to handle the '-c' option specially, because it takes a configutation parameter in a separate word, which must be skipped, too.

completion: respect 'git -C <path>' '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>
