Command to list <pattern> Branches on a specific Remote (i.e. select from rtb's)

Command to list <pattern> Branches on a specific Remote (i.e. select from rtb's)

[Philip Oakley]

Hi,
I'm unsure if there is a command for this.

Currently I have 1600+ remote tracking branches (rtb) for my Git repo as 
it covers both git.git and git-for-windows and some other contributors.

Finding a specific rtb for a particular remote looks like there ought to 
be a simple command ready to do the job, but I haven't found anything.

Is there a command or simple simple invocation of branch, show-ref, 
for-each-ref, etc that can be give a branch pattern and remote name to 
quickly filter down the list of potential branches to just one or two 
24-line screens?

That's:

    git for-each-ref 'refs/remotes/<remote>/<pattern>'
    git branch -a -l '<remote>/<pattern>'

The latter will conflate <remote> with any local branches you happen to
have prefixed with <remote>.

The reason this isn't some easy mode in some command is because there's
no hard notion that a given remote "owns" a given set of RTB's. It's
just convention, but they can and do overlap sometimes.

See the logic in 'git remote remove' that needs to decide if a deletion
of a remote should delete its remote tracking refs: 7ad2458fad ("Make
"git-remote rm" delete refs acccording to fetch specs", 2008-06-01)

Thanks, that's magic. I was also conflating the 'pattern' with a grep 
style sub-string search in my exploration.

So, as long as one uses the RTB 'remote name', rather than the remotes 
'remote name' it should all be golden.

I'll add the answer to one on the stackoverflow Q&A's I'd looked at. I 
hadn't put the branch -a and -l options together.

deffo on an update! For the -r option I did not expect to be able to add 
a remote name (no option listed, nor method noted).

Just re-read the branch(1) man page and much of it is buried in the 
first paragraph with/for the --list option with lots of caveats and 
pairings.

I guess you were referring to you more recent reply to Ævar.

However, isn't `-r <pattern>` broken?

The docs for the branch -r and -a option could do with mentioning that 
they are meant to accept a pattern, as all the other mentions are hidden 
mid paragraph.

I'll prepare a v2 for the docs, but haven't the time at the moment to 
investigate the code fail (missing a test?).

You are asking "branch --all --list" here.

You wanted to ask "branch --remote --list" instead of "branch --all

Then why does it say:
     fatal: -a and -r options to 'git branch' do not make sense with a 
branch name

when there is no `-a` given?

The initial expectation was that a simple "--remote <pattern>" would be 
all that was required to list the rtbs with the sub-pattern (see fatal 
above, which is maybe how Ævar got his -a formulation). But it now 
appears that we/I need the --list, to allow a pattern, and either -a, or 
-r, to include the rtbs in the list.

So ultimately, yes, to just get the rtbs of a specific remote one needs 
your "branch --remote --list `<remote>/*' "formulation.

[RFC/PATCH v2] doc branch: provide examples for listing remote tracking branches

[Philip Oakley]

The availability of these pattern selections is not obvious from
the man pages, as per mail thread <87lfz3vcbt.fsf@evledraar.gmail.com>.

Provide examples.

Re-order the `git branch` synopsis to emphasise the `--list <pattern>`
pairing. Also expand and reposition the `all/remotes` options.

Split the over-long description into three parts so that the <pattern>
description can be seen.

Clarify that the `all/remotes` options require the --list if patterns
are to be used.

Add examples of listing remote tracking branches that match a pattern,
including `git for-each-ref` which has more options.

Improve the -a/-r warning message. The message confused this author
as the combined -a and -r options had not been given, though a pattern
had. Specifically guide the user that maybe they needed the --list
option to enable a remote branch pattern selection.

This looks reasonable to me---is it ready to go even with its RFC prefix?

Yes; the RFC was only in regard of the die() message change as it 
touches real code;-)


Following the post, Stolee's coverage report, it was noted that the 
die() wasn't actually tested, so I sent a quick follow-up of a potential 
test 
https://public-inbox.org/git/f28dd5b1-fda8-cf51-5582-067a7d2c2472@iee.org/ 
which is a proper RFC...


I did not attempt to see if any other dies()'s were untested, just 
copied one that was..

That problem should be gone if you use -r instead of -a.

Wouldn't "branch -r -l <remote>/<pattern>" be without that downside?
Why use "-a"?
