2012-02-26git-p4: fix submit regression with clientSpec and subdir cloneLibravatar Pete Wyckoff1-32/+54
When the --use-client-spec is given to clone, and the clone path is a subset of the full tree as specified in the client, future submits will go to the wrong place. Factor out getClientSpec() so both clone/sync and submit can use it. Introduce getClientRoot() that is needed for the client spec case, and use it instead of p4Where(). Test the five possible submit behaviors (add, modify, rename, copy, delete).

The alternatives of requiring the user to set it, or providing a command-line option on every submit, are error prone.

2012-02-21completion: Allow dash as the first character for __git_ps1Libravatar Christian Hammerl1-1/+1
If the argument for `__git_ps1` begins with a dash, `printf` tries to interpret it as an option which results in an error message. The problem is solved by adding '--' before the argument to tell `printf` to not interpret the following argument as an option. Adding '--' directly to the argument does not help because the argument is enclosed by double quotes.

2012-02-06completion: work around zsh option propagation bugLibravatar Felipe Contreras1-3/+6
When listing commands in zsh (git <TAB><TAB>), all of them will show up, instead of only porcelain ones. The root cause of this is because zsh versions from 4.3.0 to present (4.3.15) do not correctly propagate the SH_WORD_SPLIT option into the subshell in ${foo:=$(bar)} expressions. Because of this bug, the list of all commands was treated as a single word in __git_list_porcelain_commands and did not match any of the patterns that would usually cause plumbing to be excluded. With problematic versions of zsh, after running emulate sh fn () { var='one two' for v in $var; do echo $v; done } x=$(fn) : ${y=$(fn)} printing "$x" results in two lines as expected, but printing "$y" results in a single line because $var is expanded as a single word when evaluating fn to compute y. So avoid the construct, and use an explicit 'test -n "$foo" || foo=$(bar)' instead.

2012-01-26git-completion: workaround zsh COMPREPLY bugLibravatar Felipe Contreras1-0/+8
zsh adds a backslash (foo\ ) for each item in the COMPREPLY array if IFS doesn't contain spaces. This issue has been reported[1], but there is no solution yet. This wasn't a problem due to another bug[2], which was fixed in zsh version 4.3.12. After this change, 'git checkout ma<tab>' would resolve to 'git checkout master\ '. Aditionally, the introduction of __gitcomp_nl in commit a31e626 (completion: optimize refs completion) in git also made the problem apparent, as Matthieu Moy reported. The simplest and most generic solution is to hide all the changes we do to IFS, so that "foo \nbar " is recognized by zsh as "foo bar". This works on versions of git before and after the introduction of __gitcomp_nl (a31e626), and versions of zsh before and after 4.3.12. Once zsh is fixed, we should conditionally disable this workaround to have the same benefits as bash users.

2011-12-21bash completion: use read -r everywhereLibravatar Thomas Rast1-6/+6
We use the 'read' command without -r, so that it treats '\' as an escape character, in several places. This breaks the loop reading refnames from git-for-each-ref in __git_refs() if there are refnames such as "foo'bar", in which case for-each-ref helpfully quotes them as $ git update-ref "refs/remotes/test/foo'bar" HEAD $ git for-each-ref --shell --format="ref=%(refname:short)" "refs/remotes" ref='test/foo'\''bar' Interpolating the \' here will read "ref='test/foo'''bar'" instead, and eval then chokes on the unbalanced quotes. However, since none of the read loops _want_ to have backslashes interpolated, it's much safer to use read -r everywhere.

2011-12-11git-p4: use absolute directory for PWD env varLibravatar Gary Gibbons1-2/+3
P4 only looks at the environment variable $PWD to figure out where it is, so chdir() has code to set that every time. But when the clone --destination is not an absolute path, PWD will not be absolute and P4 won't be able to find any files expected to be in the current directory. Fix this by expanding PWD to an absolute path. One place this crops up is when using a P4CONFIG environment variable to specify P4 parameters, such as P4USER or P4PORT. Setting P4CONFIG=.p4config works for p4 invocations from the current directory. But if the value of PWD is not absolute, it fails.

2011-10-21completion: remove broken dead code from __git_heads() and __git_tags()Libravatar SZEDER Gábor1-20/+2
__git_heads() was introduced in 5de40f5 (Teach bash about git-repo-config., 2006-11-27), and __git_tags() in 88e21dc (Teach bash about completing arguments for git-tag, 2007-08-31). As their name suggests, __git_heads() is supposed to list only branches, and __git_tags() only tags. Since their introduction both of these functions consist of two distinct parts. The first part gets branches or tags, respectively, from a local repositoty using 'git for-each-ref'. The second part queries a remote repository given as argument using 'git ls-remote'. These remote-querying parts are broken in both functions since their introduction, because they list both branches and tags from the remote repository. (The 'git ls-remote' query is not limited to list only heads or tags, respectively, and the for loop filtering the query results prints everything except dereferenced tags.) This breakage could be easily fixed by passing the '--heads' or '--tags' options or appropriate refs patterns to the 'git ls-remote' invocations. However, that no one noticed this breakage yet is probably not a coincidence: neither of these two functions were used to query a remote repository, the remote-querying parts were dead code already upon thier introduction and remained dead ever since. Since those parts of code are broken, are and were never used, stop the bit-rotting and remove them. Signed-off-by: SZEDER Gábor <szeder@ira.uka.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-10-21completion: fast initial completion for config 'remote.*.fetch' valueLibravatar SZEDER Gábor1-0/+4
Refspecs for branches in a remote repository start with 'refs/heads/', so completing those refspecs with 'git config remote.origin.fetch <TAB>' always offers 'refs/heads/' first, because that's the unique part of the possible refspecs. But it does so only after querying the remote with 'git ls-remote', which can take a while when the request goes through some slower network to a remote server. Don't waste the user's time and offer 'refs/heads/' right away for 'git config remote.origin.fetch <TAB>'. The reason for putting 'refs/heads/' directly into COMPREPLY instead of using __gitcomp() is to avoid __gitcomp() adding a trailing space.

The remote-handling part of __git_refs() has a nice for loop and state machine case statement to iterate over all words from the output of 'git ls-remote' to identify object names and ref names. Since each line in the output of 'git ls-remote' consists of an object name and a ref name, we can do more effective filtering by using a while-read loop and letting bash's word splitting take care of object names. This way the code is easier to understand and the loop will need only half the number of iterations than before.

For a local repository the __git_refs() completion helper function lists refs under 'refs/(tags|heads|remotes)/', plus some special refs like HEAD and ORIG_HEAD. For a remote repository, however, it lists all refs. Fix this inconsistency by specifying refs filter patterns for 'git ls-remote' to only list refs under 'refs/(tags|heads|remotes)/'. For now this makes it impossible to complete refs outside of 'refs/(tags|heads|remotes)/' in a remote repository, but a followup patch will resurrect that.

2011-10-21completion: optimize refs completionLibravatar SZEDER Gábor1-45/+70
After a unique command or option is completed, in most cases it is a good thing to add a trailing a space, but sometimes it doesn't make sense, e.g. when the completed word is an option taking an argument ('--option=') or a configuration section ('core.'). Therefore the completion script uses the '-o nospace' option to prevent bash from automatically appending a space to unique completions, and it has the __gitcomp() function to add that trailing space only when necessary. See 72e5e989 (bash: Add space after unique command name is completed., 2007-02-04), 78d4d6a2 (bash: Support unique completion on git-config., 2007-02-04), and b3391775 (bash: Support unique completion when possible., 2007-02-04). __gitcomp() therefore iterates over all possible completion words it got as argument, and checks each word whether a trailing space is necessary or not. This is ok for commands, options, etc., i.e. when the number of words is relatively small, but can be noticeably slow for large number of refs. However, while options might or might not need that trailing space, refs are always handled uniformly and always get that trailing space (or a trailing '.' for 'git config branch.<head>.'). Since refs listed by __git_refs() & co. are separated by newline, this allows us some optimizations with 'compgen'. So, add a specialized variant of __gitcomp() that only deals with possible completion words separated by a newline and uniformly appends the trailing space to all words using 'compgen -S " "' (or any other suffix, if specified), so no iteration over all words is needed. But we need to fiddle with IFS, because the default IFS containing a space would cause the added space suffix to be stripped off when compgen's output is stored in the COMPREPLY array. Therefore we use only newline as IFS, hence the requirement for the newline-separated possible completion words. Convert all callsites of __gitcomp() where it's called with refs, i.e. when it gets the output of either __git_refs(), __git_heads(), __git_tags(), __git_refs2(), __git_refs_remotes(), or the odd 'git for-each-ref' somewhere in _git_config(). Also convert callsites where it gets other uniformly handled newline separated word lists, i.e. either remotes from __git_remotes(), names of set configuration variables from __git_config_get_set_variables(), stashes, or commands. Here are some timing results for dealing with 10000 refs.
