Previously, some calls to for-each-ref passed fixed numbers of path
components to strip from refs, assuming that remote names had no slashes in
them. This made completions like:
git push github/dseomn :com
Result in:
git push github/dseomn :dseomn/completion-remote-slash
With this patch, it instead results in:
git push github/dseomn :completion-remote-slash
In addition, the change to __git_dwim_remote_heads() restricts it to only
list remote branches, not HEAD. I think that actually improves the
completion where it's used though, since HEAD doesn't seem to be valid
anyway:
$ git switch HEAD fatal: a branch is expected, got 'HEAD'
David Mandelberg (3):
completion: add helper to escape strings for fnmatch
completion: add helper to count path components
completion: fix bugs with slashes in remote names

This sounds like a useful improvement and I like the idea, but I think
running "git for-each-ref" once for each remote is not going to scale
very well for people who have a lot of remotes. I think it would be
better to try and strip "refs/remote/$remote/" outside of "git
for-each-ref". I've not tested it but I think something like
local sed_cmd=
local remote
# ref names and therefore remote names cannot contain '*?[]^' so we
# only need to escape '.$/'. Using 'sort -r' means that if there is a
# remote called "github" and another called "github/alice" we will try
# and strip "github/alice" first.
for remote in $(__git_remotes | sort -r)
do
remote="${remote//./\\./}"
remote="${remote//\$/\\\$/}"
remote="${remote//\//\\\//}"
sed_cmd="${sed_cmd} -e s/^refs\/remotes\/$remote\/// -e t"
done
__git for-each-ref --format="$fer_pfx$sfx" \
${GIT_COMPLETION_IGNORE_CASE+--ignore-case} \
"refs/remotes/*/$cur_*" "refs/remotes/*/$cur_*/**" |
sed $sed_cmd | sort -u
should work and means we're only forking three extra processes no matter
how many remotes the user has. I'm not sure if it changes the output
order when GIT_COMPLETION_IGNORE_CASE is set though.
Best Wishes

Good point, I hadn't thought of that. Do you have a rough estimate of
what "a lot of remotes" is? 100ish, maybe? I'd like to do some testing
to get actual performance numbers before trying to optimize this,
because I think the optimization has some drawbacks, see below.
If optimization is needed, another approach is to parallelize the forks:
{
local fer_pids=
for ...
do
__git for-each-ref ... &
fer_pids="$fer_pids $!"
done
test -z "$fer_pids" || wait $fer_pids
} | sort | uniq -u
That might cause spikes in cpu/memory/disk usage that aren't ideal though.

Just FYI since it took me hours to figure this out myself: I think this
would break tests on macos because of an old version of bash that
handles backslashes weirdly. I think removing the double quotes would
work around that issue, and be safe because word splitting doesn't
happen in assignments.

Mostly just a note to myself if I end up using this idea: I think a
space in $remote would break this because bash would split up the arg to
sed. There's probably some way to fix that with extra escaping though?

This would search for $cur_ in the wrong place because * only matches
one path component, right? Changing to ** might help, but then it would
match in places more it shouldn't.

I'm not really sure what a "large" number looks like for people who
track a lot of repositories. On windows forking is pretty slow (our
shell-based test suite is incredibly slow on that platform) so I think
it makes sense to try and avoid adding new processes.

Yes, if there were a 100 remotes that's a bit of a fork-bomb.

Thanks, I'm not familiar with bash's extensions to parameter
substitution. The completions can also but used under zsh
(git-completion.zsh is pretty much abandoned I think) but it looks like
bash and zsh agree on this expansion.

I should have said in the comment above that ref names cannot contain
space, tab, newline etc. so we don't have to worry about the shell's
word splitting splitting the patterns. They cannot contain backslashes
either.

Oh, good point I'd missed that. Could we change sed to run with '-n' and
generate an expression that looks like
-e s|^refs/remotes/$remote/\($cur_\)|\1|p -e t
with the appropriate escaping of $remote and $cur_ so that we only print
the output of for-each-ref that matches $cur_?

Thanks, I didn't know about forking being slow on Windows.
Do you know if we need to worry about hitting the max number or length
of arguments to a command?
https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/limits.h.html
under _POSIX_ARG_MAX says that at least 4KiB should be supported, which
seems low enough to maybe cause trouble, but it's a minimum.
https://www.in-ulm.de/~mascheck/various/argmax/ lists a bunch of values
for different platforms, and from a brief scan it looks like all the
remotely-modern platforms have values that are probably large enough for
this.

I also realized after sending that email that it could run into issues
with the number of available PIDs too. It could be improved by limiting
to n child processes at a time and waiting for one to finish before
starting the next, but that's more complication. I think your solution
below is better.

The tests don't automatically run under zsh though, right? Maybe I
should try to figure out how to do that in a separate patch...

Good to know. Is https://git-scm.com/docs/git-check-ref-format the place
I should have read to understand what escaping is needed and what isn't
because of the limitations on ref names?

I think that would work. I was hoping to avoid sed, and I was thinking
about using shell's ${parameter#word} to strip and test for matching
prefixes. But I can't think of a way to do that with
GIT_COMPLETION_IGNORE_CASE. Modern bash has ${parameter@L} to lowercase
a string, but I don't think the version of bash on macos has that. With
sed it would just be a matter of adding the i flag if needed.
I don't think this is an issue, but do we need to worry about putting
remote names and $cur_ on the command line where any other user on the
same system can read them? $cur_ was already on the command line before
this patch, and remote names appear on other git command lines all the
time, so I doubt they're meant to be secret.
Is a Helped-by trailer the right way to credit you for your suggestions
on this?

5.
In Git for Windows fork()-ing subshells and fork()+exec()-ing
processes is rather costly, about an order of magnitude slower than on
Linux. The rough equivalent of the body of your loop, with two
subshells and a git process:
time { a=$(echo 1) ; b=$(echo 2) ; git for-each-ref >/dev/null ; }
takes on average 0.17s on a windows box I have access to (with fully
packed refs, and merely 4 refs in total). So guess at about 4-5
remotes it would take over a second to react to my TABs...
I would rather try to go in the opposite direction to see whether 'git
for-each-ref' could be taught to strip the "refs/remote/$remote/"
prefix with a format specifier option like '%(refname:strip=remote)'.
That would surely be faster than any shell filtering we might come up
with, and would also save us from the trouble of escaping glob and/or
regex metacharacters for shell/sed pattern matching.

Please don't do this, the completion script must not forkbomb the
system.

I haven't followed this discussion closely, but you can
also use ${parameter,,} to do parameter case modification.
Sadly, it looks like those were added in bash-4.0, so Apple
will have kept their users from benefiting from that to
avoid GPLv3 code. :/
I don't have an ancient bash-3.x like MacOS to test, but
maybe they've backported some features?
Though if you do end up using this, ${parameter,,} will work
in a much wider range of bash version that ${parameter@L}
which covers various releases in the OS's we aim to target
(e.g. RHEL 8.x, which has bash-4.4).

Oh wow, that's much slower than I expected, thanks for the numbers!

That doesn't fix the issue of needing to anchor the $cur_ part of the
pattern after each refs/remote/$remote/ prefix. It might be possible to
use something like %(refname:strip=remote) to find all remote branches
with the remote stripped, then filter them for $cur_ in the shell or
with sed though.
What are the expectations around mixing versions of git itself and files
in contrib? Can a single patch series add a feature to for-each-ref and
use it in git-completion.bash, or does the feature in for-each-ref need
to exist for some time before git-completion.bash can use it?

And they are all competing for a shared common resource for read
access.
I wonder if a single invocation of for-each-ref for refs/remotes/
hierarchy would be sufficient? That is, the calling shell script
can set up a shell function "foo" and then
eval $(for-each-ref --format='foo %(refname)' --shell refs/remotes/)
and "foo" can do its thing avoiding as much forks as possible. As
you are allowed bash-ism in completion script, you do not have to
limit yourself to POSIX parameter substitution but can use substring
expansion ${parameter:offset:length} and pattern substitution
${parameter/pattern/string} and other kind of bash exotics, as well
as shell arrays (e.g., define an array __git__remote_branches[] for
each remote, which may contain the remote-tracking branches for the
remote).

Thanks everyone for all the reviews! I rewrote __git_dwim_remote_heads
to fork a constant number of times instead of a multiple of the number
of remotes. There are still a handful of forks, but I think they can
mostly be parallelized.
I tried to find a pure shell implementation like a few of you mentioned,
but I couldn't think of one that would work in both bash 3.2 (the
version on macOS, I think?) and zsh. The only thing I found in
https://www.bashcookbook.com/bashinfo/source/bash-3.2/doc/bash.html that
looked like it would work to implement GIT_COMPLETION_IGNORE_CASE was
the nocasematch arg to shopt, but
https://zsh.sourceforge.io/Doc/Release/zsh_14.html#index_split-13_fn_letter-S
doesn't list shopt at all.
One unintentional difference with this approach is that $cur_ is no
longer treated as a glob pattern. Was it supposed to be in the first
place though, or was that just because of missing escaping? I.e., this
no longer works to complete unique-remote-branch:
git checkout unique-remote-br*<Tab>
In my original commit message, I mentioned that HEAD was no longer
listed, but I think I was wrong about that. I think HEAD went away in a
bunch of the tests because I added another remote, so HEAD was no longer
unique. Maybe HEAD should be filtered out too, but that seems like a
separate issue for a separate patch.

A follow-up commit will use this with for-each-ref to strip the right
number of path components from refnames.

Previously, some calls to for-each-ref passed fixed numbers of path
components to strip from refs, assuming that remote names had no slashes
in them. This made completions like:
git push github/dseomn :com<Tab>
Result in:
git push github/dseomn :dseomn/completion-remote-slash
With this patch, it instead results in:
git push github/dseomn :completion-remote-slash

I wonder if we can use "sort -u" here and drop uniq. It isn't quite the
same as it will remove entries that are equal according to the current
locale but I don't think that should matter.

With that tweak this looks good. If there are no glob characters then
"git for-each-ref" does a prefix match so strictly speaking you don't
need the '**' but I don't think it matters in practice. I had one
thought below but if you don't feel like spending more that on this I
think what you have here is fine.
The filtering is O(number of remote refs * number of remotes). If we
could sort the list of remotes and remote refs in the same order then we
can reduce this to O(number of remote refs + number of remotes) by doing
(in pseudo code)
for ($ref in $remote_refs) {
while (!starts_with($ref, "refs/remotes/$remote[$i]"))
$i++;
if (starts_with($ref, "refs/remotes/$remote[$i]/$cur_)
print $ref;
}
I think we can get "git for-each-ref --sort=-refname" and "sort -r" to
agree on a sorting order by setting LC_COLLATE=C, otherwise "sort" will
sort according the the current locale whereas git sorts by bytes.
Best Wishes

That's what I thought when I first saw that, but `uniq -u` removes
duplicates:
$ printf 'a\nb\na\n' | sort | uniq -u
b
$ printf 'a\nb\na\n' | sort -u
a
b

On my desktop, a similar-ish loop takes about 0.1s with 1000*1000
iterations. 1000 remote branches seems plausible but on the high side to
me, and 1000 remotes seems very high to me. Do you still think it's
worth optimizing? I do think your solution would work, but I think it
would take a decent amount of testing to avoid the collation issues you
mentioned, and off-by-one errors and the like. So I'd rather not do it
unless there's a practical performance advantage, not just theoretical.
(Which is what I thought about minimizing forks too, before I learned
that it was a practical issue.)
$ time seq 1 1000 | LONG="$(seq 1 1000)" awk 'BEGIN {
split(ENVIRON["LONG"], long, /\n/); } { for (i in long) { if ($0 ==
long[i]) { print; } } }' > /dev/null

I don't think "abandoned" is the right characterization—at least, it's
the completion script that Homebrew-installed Git users will get for
Zsh, and it does re-use the Bash completion scripts (which therefore
ought to stay portable between both if possible, otherwise we get
stuff like 8776470cf3 (completion: repair config completion for Zsh,
2025-01-06)). The Zsh script has seen some fixups over time (such as
my own 3c20acdf46 (completion: zsh: stop leaking local cache variable,
2024-04-30)).

Correct—which is how bugs sneak in ;)
I'm willing to manually test the patch if I can understand how to
reproduce the issue—it sounds like having a remote name with a slash
is sufficient?
I started trying to test Zsh completion a while back when working on
one of the patches mentioned above; I got as far as this hack [1],
which is to say, not very far at all.

Apparently I am late to the party, but I have to wonder how
prevalent it is to use such a name for remotes.
Back in 2005 when I designed the remote namespaces and
remote-tracking branches, the code may have been loose not to
complain, but it certainly was not an intended way the remote names
and remote-tracking hiearchies were to be used. Being able to say
"refs/remote/*/master" and learn where everybody's 'master' branch
points at with a single globbing was a powerful thing, but with
refs/remotes/github/dseomn/master thrown into the mix, that would
break down miserably. As a remote name, we still do use "is that a
file on the filesystem?" to see if it is a local file:// URL
(i.e. "git fetch github/dseomn" may be fetching from a subdirectory
two levels down); in retrospect, we might have been better off if we
said "well with a slash it must be a local directory and not remote
nickname" to prevent such usage pattern.
Anyway, this is not something we'd do lightly, but we may want to
see if we should tighten the naming rules for remote nicknames and
the mapping from nicknames to remote-tracking hiearchy, at Git 3.0
version boundary.

Thanks for clarifying that, I'd misunderstood the relationship between
git-completion.zsh and git-completion.bash.

From a quick search, it looks like I'm not the only one, but I don't
know how common it is: https://github.com/desktop/desktop/issues/3618
I'm not sure if I'm remembering right, but I think I got the idea from
seeing slashes in branch names to organize a hierarchy of branches, and
realizing I could do the same with remotes. Was it intentional to allow
slash in branch names, or is that a similar situation?

That's a good reason not to use slashes in remotes that I didn't know
about, thanks!

What does that mean for this patch now? Do you want to fix the
completion for the currently (unintentionally) supported remote names,
or leave it broken to discourage their use? Fixing the completion might
also give anybody reading the completion script the idea that slashes in
remote names are somewhat sanctioned.

Reference names were hierarchical pretty much from the beginning.

It probably would not mean much either way, and certainly not
something we should worry about during pre-release feature freeze.
The "fix" may take quite different shapes. Remote nick/name may
still be allowed but the default fetch refspec left by "git clone"
would start using the refs/remotes/nick-name/ hierarchy instead of
the refs/remotes/nick/name hierarchy, for example, but as long as
this round of completion fixes properly read the configuration to
learn the remote-tracking hierarchy by reading the configured value
of "remote.nick/name.fetch", such a change would not break the code
in the completion script at all. Or remote nick/name may outright
banned and people are encouraged to use nick-name instead, in which
case even if the completion code is prepared to accept remote names
with slashes in it, as long as it still works correctly with remote
names with no slashes in it, it will keep working in such a future.
Or the "fix" may be to declare "there is nothing to fix, if people
want to use
[remote "nick/name"] fetch = +refs/heads/*:refs/remotes/nickname/*
[remote "nocknyme"] fetch = +refs/heads/*:refs/remotes/nock/nyme/*
that's their choice, and the completion code would do the right thing
anyway".
I didn't read your patches, so the situation may be different and
with any shape of "fix", or without any "fix", there might still be
need for further polishing. But hopefully you got the idea. For
this particular patch, there is nothing urgently needed. Well, we
are right now in the pre-release feature freeze anyway ;-).
Thanks.

Thanks for the explanation!

Btw, I just tested it, and I think this is an issue for remote names
without slashes too:

Yes, and that is an intended way local repositories are discovered
and used.
The problem with slashes is that the mistake surface becomes a lot
larger. "ls<RETURN>" would show you "origin" immediately in the
current working directory, but you wouldn't know if origin has
origin/foo or origin/bar unless you look. Limiting the local
filesystem reference to something like "only the ones that has no
slashes, or begin with ../ or /" would make it less likely that you
meant to push to somewhere and instead push to a local directory.

Yup. I was able to reproduce it with these commands:
/tmp/tmp.zOjfmdMx1i$ git init foo
Initialized empty Git repository in /tmp/tmp.zOjfmdMx1i/foo/.git/
/tmp/tmp.zOjfmdMx1i$ cd foo

[main (root-commit) 4b95a99] test
/tmp/tmp.zOjfmdMx1i/foo$ git update-ref refs/remotes/with/slash/main 4b95a99
Then type:
git push with/slash :ma<Tab>

Thanks; in Zsh the results after :<Tab> are HEAD and main. After
:ma<Tab>, just main. The results with _no_ colon are HEAD, main,
with/slash/main. I think that's all the expected results?
My test procedure was to
git fetch <your PR tip>
mv /usr/local/share/zsh/site-functions/git-completion.bash{,.bak}
git show FETCH_HEAD:contrib/completion/git-completion.bash >
/usr/local/share/zsh/site-functions/git-completion.bash
# adjust startup files to use `compinit -D` to avoid caches

It's been a bit over a week since the last version of this, with some
discussion, but I don't think any requests for changes. So here's an
updated version with the minor performance change I mentioned in

A follow-up commit will use this with for-each-ref to strip the right
number of path components from refnames.

Previously, some calls to for-each-ref passed fixed numbers of path
components to strip from refs, assuming that remote names had no slashes
in them. This made completions like:
git push github/dseomn :com<Tab>
Result in:
git push github/dseomn :dseomn/completion-remote-slash
With this patch, it instead results in:
git push github/dseomn :completion-remote-slash

Just a bit of curiosity, but how would this be different from using
__git for-each-ref --format='%(refname)' refs/remotes/
i.e. the prefix match, here? Does the wildmatcher clever enough to
optimize "**" away and make it just to iterate over refs/remotes/
hierarchy without filtering anything?

Oh right, I lost track of that bit. When I wrote that, I didn't know
that for-each-ref did prefix matching. Phillip Wood pointed it out:
> If there are no glob characters then "git for-each-ref" does a prefix match so strictly speaking you don't need the '**' but I don't think it matters in practice.
But I forgot about it when I sent v3.
Do you want me to change it? Should I send a v4 now, or just make a
fixup commit locally so I don't forget it when I send a v4 in the future?

Entirely up to you. I do not plan to perform an in-detail review on
the topic (I do not consider myself quite qualified), but others who
saw earlier rounds of the patch may want to say "now this is perfect"
or "now this is perfect with this and that changes", and if you do not
think the differenes between v3 and your upcoming v4 are small enough,
it may be more efficient to wait for a bit to collect more comments.
Thanks.

I'm not an expert on our completion script but from a general shell
scripting perspective this version looks fine to me.

OK, then let me see if I can squash in before merging the topic to
'next'.

Another minor change, as suggested by
https://lore.kernel.org/git/xmqqo6y3dzno.fsf@gitster.g/
I'm not sure what the expectations are around updating patches that are
scheduled to be merged to next but haven't been merged yet. If it's too
late, I'm happy with the previous v3, or I could send a separate patch.

A follow-up commit will use this with for-each-ref to strip the right
number of path components from refnames.

From: David Mandelberg @ 2025-03-23 21:06 UTC (permalink / raw)
To: David Mandelberg via GitGitGadget; +Cc: git, Jacob Keller, Junio C Hamano
Previously, some calls to for-each-ref passed fixed numbers of path
components to strip from refs, assuming that remote names had no slashes
in them. This made completions like:
git push github/dseomn :com<Tab>
Result in:
git push github/dseomn :dseomn/completion-remote-slash
With this patch, it instead results in:
git push github/dseomn :completion-remote-slash
Signed-off-by: David Mandelberg <david@mandelberg.org>

Unless a patch series has already been merged to next which in not the
case here sending a new round of patches like this is the right thing to
do. The range-diff (which you can add to your cover letter by passing
"--range-diff" to "git format-patch") below looks good to me
Sorry for the slow response and thanks for working on this

Makes sense, thanks!

Oh, nice. I only learned about range-diff recently and it's my new
favorite git command. I'll use `git format-patch --range-diff` in the
future.
