* [PATCHv2 21/21] completion: cache the path to the repository
From: SZEDER Gábor @ 2017-02-03 2:48 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203024829.8071-1-szeder.dev@gmail.com>
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.

* [PATCHv2 09/21] completion: respect 'git --git-dir=<path>' when listing remote refs
From: SZEDER Gábor @ 2017-02-03 2:48 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203024829.8071-1-szeder.dev@gmail.com>
In __git_refs() the git commands listing refs, both short and full,
from a given remote repository are run without giving them the path to
the git repository which might have been specified on the command line
via 'git --git-dir=<path>'. This is bad, those git commands should
access the 'refs/remotes/<remote>/' hierarchy or the remote and
credentials configuration in that specified repository.
Use the __gitdir() helper only to find the path to the .git directory
and pass the resulting path to the 'git ls-remote' and 'for-each-ref'
executions that list remote refs. While modifying that 'for-each-ref'
line, remove the superfluous disambiguating doubledash.
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.
We are better off to perform all the necessary checks of the remote in
__git_refs().
Though __git_refs() was the last remaining callsite that passed a
remote to __gitdir(), don't delete __gitdir()'s remote-handling part
yet, just in case some users' custom completion scriptlets depend on
it.

* [PATCHv2 14/21] completion: fix completion after 'git -C <path>'
From: SZEDER Gábor @ 2017-02-03 2:48 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203024829.8071-1-szeder.dev@gmail.com>
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.

* [PATCHv2 06/21] completion tests: add tests for the __git_refs() helper function
From: SZEDER Gábor @ 2017-02-03 2:48 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203024829.8071-1-szeder.dev@gmail.com>
Check how __git_refs() lists refs in different scenarios, i.e.
- short and full refs,
- from a local or from a remote repository,
- remote specified via path, name or URL,
- with or without a repository specified on the command line,
- non-existing remote,
- unique remote branches for 'git checkout's tracking DWIMery,
- not in a git repository, and
- interesting combinations of the above.
Seven of these tests expect failure, mostly demonstrating bugs related
to listing refs from a remote repository:
- ignoring the repository specified on the command line (2 tests),
- listing refs from the wrong place when the name of a configured
remote happens to match a directory,
- listing only 'HEAD' but no short refs from a remote given as URL,
- listing 'HEAD' even from non-existing remotes (2 tests), and
- listing 'HEAD' when not in a repository.

* [PATCH 00/12] completion: speed up refs completion
From: SZEDER Gábor @ 2017-02-03 2:53 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
This series speeds up refs completion for large number of refs, partly
by giving up disambiguating ambiguous refs (patch 6) and partly by
eliminating most of the shell processing between 'git for-each-ref'
and 'ls-remote' and Bash's completion facility. The rest is a bit of
preparatory reorganization, cleanup and bugfixes.
The last patch touches the ZSH wrapper, too. By a lucky educated
guess I managed to get it work on the first try, but I don't really
know what I've actually done, so... ZSH users, please have a closer
look.
At the end of this series refs completion from a local repository is
as fast as it can possibly get, at least as far as the completion
script is concerned, because it basically does nothing anymore :) All
it does is run 'git for-each-ref' with assorted options to do all the
work, and feed its output directly, without any processing into Bash's
COMPREPLY array. There is still room for improvements in the code
paths using 'git ls-remote', but for that we would need enhancements
to 'ls-remote'.
It goes on top of the __gitdir() improvements series I just posted at:
http://public-inbox.org/git/20170203024829.8071-1-szeder.dev@gmail.com/T/
This series is also available at:
https://github.com/szeder/git completion-refs-speedup
SZEDER Gábor (12):
completion: remove redundant __gitcomp_nl() options from _git_commit()
completion: wrap __git_refs() for better option parsing
completion: support completing full refs after '--option=refs/<TAB>'
completion: support excluding full refs
completion: don't disambiguate tags and branches
completion: don't disambiguate short refs
completion: let 'for-each-ref' and 'ls-remote' filter matching refs
completion: let 'for-each-ref' strip the remote name from remote
branches
completion: let 'for-each-ref' filter remote branches for 'checkout'
DWIMery
completion: let 'for-each-ref' sort remote branches for 'checkout'
DWIMery
completion: list only matching symbolic and pseudorefs when completing
refs
completion: fill COMPREPLY directly when completing refs

__gitcomp_nl() would use anyway when invoked with no options at all.

* [PATCH 02/12] completion: wrap __git_refs() for better option parsing
From: SZEDER Gábor @ 2017-02-03 2:53 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203025405.8242-1-szeder.dev@gmail.com>
__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.

* [PATCH 07/12] completion: let 'for-each-ref' and 'ls-remote' filter matching refs
From: SZEDER Gábor @ 2017-02-03 2:54 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203025405.8242-1-szeder.dev@gmail.com>
When completing refs, several __git_refs() code paths list all the
refs from the refs/{heads,tags,remotes}/ hierarchy and then
__gitcomp_nl() iterates over those refs in a shell loop to filter out
refs not matching the current word to be completed. This comes with a
considerable performance penalty when a repository contains a lot of
refs but the current word can be uniquely completed or when only a
handful of refs match the current word.
Specify appropriate globbing patterns to 'git for-each-ref' and 'git
ls-remote' to list only those refs that match the current word to be
completed. This reduces the number of iterations in __gitcomp_nl()
from the number of refs to the number of matching refs.
This speeds up refs completion considerably when there are a lot of
non-matching refs to be filtered out. Uniquely completing a branch in
a repository with 100k local branches, all packed, best of five:
On Linux, before:
$ time __git_complete_refs --cur=maste
real 0m0.831s
user 0m0.808s
sys 0m0.028s
After:
real 0m0.119s
user 0m0.104s
sys 0m0.008s
On Windows, before:
real 0m1.480s
user 0m1.031s
sys 0m0.060s
After:
real 0m0.377s
user 0m0.015s
sys 0m0.030s
Strictly speaking this is a fundamental behavior change in
__git_refs(), a helper function that is likely used in users' custom
completion scriptlets. However, arguably this change should be
harmless, because:
- __git_refs() was only ever intended to feed refs to Bash's
completion machinery, for which non-matching refs have to be
filtered out anyway.
- There were already code paths that list only matching refs
(listing unique remote branches for 'git checkout's tracking
DWIMery and listing full remote refs via 'git ls-remote').

* [PATCH 03/12] completion: support completing full refs after '--option=refs/<TAB>'
From: SZEDER Gábor @ 2017-02-03 2:53 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203025405.8242-1-szeder.dev@gmail.com>
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).

* [PATCH 08/12] completion: let 'for-each-ref' strip the remote name from remote branches
From: SZEDER Gábor @ 2017-02-03 2:54 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203025405.8242-1-szeder.dev@gmail.com>
The code listing unique remote branches for 'git checkout's tracking
DWIMery uses a shell parameter expansion in a loop iterating over each
listed ref to remove the remote's name from the remote branches, i.e.
the leading path component from the short ref. When listing refs from
a configured remote repository, '| sed s///' is used for the same
purpose.
Let 'git for-each-ref' strip one more leading path component from the
refs, i.e. use the format 'refname:strip=3' instead of '=2', making
that parameter expansion and 'sed' execution unnecessary.
This speeds up refs completion for 'git checkout'. Uniquely
completing a branch for 'git checkout maste<TAB>' in a repo with 100k
remote branches, all packed, best of five:

* [PATCH 12/12] completion: fill COMPREPLY directly when completing refs
From: SZEDER Gábor @ 2017-02-03 2:54 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203025405.8242-1-szeder.dev@gmail.com>
__gitcomp_nl() iterates over all the possible completion words it gets
as argument
- filtering matching words,
- appending a trailing space to each matching word (in all but two
cases),
- prepending a prefix to each matching word (when completing words
after e.g. '--option=<TAB>' or 'master..<TAB>'), and
- adding each matching word to the COMPREPLY array.
This takes a while when a lot of refs are passed to __gitcomp_nl().
The previous changes in this series ensure that __git_refs() lists
only refs matching the current word to be completed, making a second
filtering in __gitcomp_nl() redundant.
Adding the necessary prefix and suffix could be done in __git_refs()
as well:
- When refs come from 'git for-each-ref', then that prefix and
suffix could be added much more efficiently using a 'git
for-each-ref' format containing said prefix and suffix.
- When refs come from 'git ls-remote', then that prefix and suffix
can be added in the shell loop that has to process 'git
ls-remote's output anyway.
- Finally, the prefix and suffix can be added to that handful of
potentially matching symbolic and pseudo refs right away in the
shell loop listing them.
And then all what is still left to do is to assign a bunch of
newline-separated words to a shell array, which can be done without a
shell loop iterating over each word, basically making all of
__gitcomp_nl() unnecessary for refs completion.
Add the helper function __gitcomp_direct() to fill the COMPREPLY array
with prefiltered and preprocessed words without any additional
processing, without a shell loop, with just one single compound
assignment. Modify __git_refs() to accept prefix and suffix
parameters and add them to each and every listed ref. Modify
__git_complete_refs() to pass the prefix and suffix parameters to
__git_refs() and to feed __git_refs()'s output to __gitcomp_direct()
instead of __gitcomp_nl().
This speeds up refs completion when there are a lot of refs matching
the current word to be completed. Listing all branches for completion
in a repo with 100k local branches, all packed, best of five:

* [PATCH 10/12] completion: let 'for-each-ref' sort remote branches for 'checkout' DWIMery
From: SZEDER Gábor @ 2017-02-03 2:54 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203025405.8242-1-szeder.dev@gmail.com>
When listing unique remote branches for 'git checkout's tracking
DWIMery, __git_refs() runs the classic '... |sort |uniq -u' pattern to
filter out duplicate remote branches.
Let 'git for-each-ref' do the sorting, sparing the overhead of
fork()+exec()ing 'sort' and a stage in the pipeline where potentially
relatively large amount of data can be passed between two subsequent
pipeline stages.
This speeds up refs completion for 'git checkout' a bit when a lot of
remote branches match the current word to be completed. Listing a
single local and 100k remote branches, all packed, best of five:

* [PATCH 11/12] completion: list only matching symbolic and pseudorefs when completing refs
From: SZEDER Gábor @ 2017-02-03 2:54 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203025405.8242-1-szeder.dev@gmail.com>
The previous changes in this series ensure that __git_refs() lists
only refs that match the current word to be completed, but
non-matching symbolic and pseudo refs still show up in its output.
Filter out non-matching symbolic and pseudo refs as well, so anything
__git_refs() outputs matches the current word to be completed, as it
will allow us to optimize how refs are placed into the COMPREPLY
array.

* [PATCH 06/12] completion: don't disambiguate short refs
From: SZEDER Gábor @ 2017-02-03 2:53 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203025405.8242-1-szeder.dev@gmail.com>
When the completion script lists short refs it does so using the 'git
for-each-ref' format 'refname:short', which makes sure that all listed
refs are unambiguous. While disambiguating refs is technically
correct in this case, as opposed to the cases discussed in the
previous patch, this disambiguation involves several stat() syscalls
for each ref, thus, unfortunately, comes at a steep cost especially on
Windows and/or when there are a lot of refs to be listed. A user of
Git for Windows reported[1] 'git checkout <TAB>' taking ~11 seconds in
a repository with just about 4000 refs.
However, it's questionable whether ambiguous refs are really that bad
to justify that much extra cost:
- Ambiguous refs are not that common,
- even if a repository contains ambiguous refs, they only hurt when
the user actually happens to want to do something with one of the
ambiguous refs, and
- the issue can be easily circumvented by renaming those ambiguous
refs.
- On the other hand, apparently not that many refs are needed to
make refs completion unacceptably slow on Windows,
- and this slowness bites each and every time the user attempts refs
completion, even when the repository doesn't contain any ambiguous
refs.
- Furthermore, circumventing the issue might not be possible or
might be considerably more difficult and requires various
trade-offs (e.g. working in a repository with only a few selected
important refs while keeping a separate repository with all refs
for reference).
Arguably, in this case the benefits of technical correctness are
rather minor compared to the price we pay for it, and we are better
off opting for performance over correctness.
Use the 'git for-each-ref' format 'refname:strip=2' to list short refs
to spare the substantial cost of disambiguating.
This speeds up refs completion considerably. Uniquely completing a
branch in a repository with 100k local branches, all packed, best of

* [PATCH 05/12] completion: don't disambiguate tags and branches
From: SZEDER Gábor @ 2017-02-03 2:53 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, SZEDER Gábor
In-Reply-To: <20170203025405.8242-1-szeder.dev@gmail.com>
When the completion script has to list only tags or only branches, it
uses the 'git for-each-ref' format 'refname:short', which makes sure
that all listed tags and branches are unambiguous. However,
disambiguating tags and branches in these cases is wrong, because:
- __git_tags(), the helper function listing possible tagname
arguments for 'git tag', lists an ambiguous tag
'refs/tags/ambiguous' as 'tags/ambiguous'. Its only consumer,
'git tag' expects its tagname argument to be under 'refs/tags/',
thus it interprets that abgiguous tag as
'refs/tags/tags/ambiguous'. Clearly wrong.
- __git_heads() lists possible branchname arguments for 'git branch'
and possible 'branch.<branchname>' configuration subsections.
Both of these expect branchnames to be under 'refs/heads/' and
misinterpret a disambiguated branchname like 'heads/ambiguous'.
Furthermore, disambiguation involves several stat() syscalls for each
tag or branch, thus comes at a steep cost especially on Windows and/or
when there are a lot of tags or branches to be listed.
Use the 'git for-each-ref' format 'refname:strip=2' instead of
'refname:short' to avoid harmful disambiguation of tags and branches
in __git_tags() and __git_heads().

The code listing unique remote branches for 'git checkout's tracking
DWIMery outputs only remote branches that match the current word to be
completed, but the filtering is done in a shell loop iterating over
all remote refs.
Let 'git for-each-ref' do the filtering, as it can do so much more
efficiently and we can remove that shell loop entirely.
This speeds up refs completion for 'git checkout' considerably when
there are a lot of non-matching remote refs to be filtered out.

* possible bug: inconsistent CLI behaviour for empty user.name
From: bs.x.ttp @ 2017-02-03 4:13 UTC (permalink / raw)
To: git
The problem is that GIT accepts a user.name of " " for some operations (for example when doing a simple "git commit"), but does require a "non-empty" user.name for others (like git commit --amend and git rebase). In case of the latter commands GIT fails with the message "fatal: empty ident name (for <email@address>) not allowed".
As people tend to do simple commits first, before amending or rebasing something, they may have to change their name after some dozen of commits which doesn't look nice.
This is certainly not a big issue, but it turns out to be quite annoying and I've already rewritten the history of a GIT repository once because of it, so that all my commits had the same author.
Proposed solution: GIT's requirements for user.name should not depend on the operation. Either user.name should be enforced to be non-empty everywhere or an empty user.name should be accepted everywhere. Perhaps filling out one of user.name and user.email could be sufficient.

Nice! This is something i've been bothered by in the past since
completion would take a rather long time!

$ git show -s --pretty='%cd | %an' --date=format:%FT%R:%S

I have no idea how portable this might be. As "git help log" says:
--date=format:... feeds the format ... to your system
strftime. Use --date=format:%c to show the date in your system
locale’s preferred format. See the strftime manual for a complete list
of format placeholders.

Ah, that does indeed do exactly what I want. Thank you.

It should be fine for my purposes.
Any idea why "%<(19,trunc)cl" doesn't work? (Your solution solves my
original problem perfectly but I'd like to understand how I'm
misreading the spec.)

Next step: solve the

You're almost there. Just insert another '%' between "trunc)" and "cI".

You'll get an ellipsis at the end though.. (i.e. 02:13... | Hilco)
