If no arguments are given, we pass "-10". This seems fairly arbitrary, doesn't it? My own working theory is that Nanako put it in because the git-log|sed construct inherently bars any way to a pager, so it needs to be cut short. So suppose we could somehow get rid of the |sed... like if we had --pretty specifiers for the reflog information. Sadly git log -g --format="%h %g: %G" still fails to exactly replicate the reflog format: if the reflog was cut off during garbage collection, the last entry refers to a no longer existing commit causing a stray ':' on that line. Oh, well. It's also still RFC because: * I don't like the massive code churn in 2/5, maybe someone sees a better option. * 5/5 has a pretty lame excuse. I could also just change it in 'git stash list' to limit the backwards-incompatibility damage, but that's also a maintenance headache. Thomas Rast (5): reflog-walk: refactor the branch@{num} formatting Introduce new pretty formats %g and %G for reflog information stash: Use new %g/%G formats instead of sed stash list: drop the default limit of 10 stashes stash: change built-in ref to 'stash' instead of 'refs/stash' archive.c | 2 +- builtin-branch.c | 3 +- builtin-checkout.c | 2 +- builtin-commit.c | 4 +- builtin-log.c | 2 +- builtin-merge.c | 2 +- builtin-rev-list.c | 2 +- builtin-shortlog.c | 2 +- builtin-show-branch.c | 2 +- commit.h | 7 +++- git-stash.sh | 10 +----- log-tree.c | 4 +- pretty.c | 20 +++++++++++-- reflog-walk.c | 72 ++++++++++++++++++++++++++++++++++--------------- reflog-walk.h | 7 +++++ 15 files changed, 94 insertions(+), 47 deletions(-) ``` ## Thomas Rast, 2009-10-12 21:06 Subject: [RFC PATCH 1/5] reflog-walk: refactor the branch@{num} formatting Message-ID: <1c524798bde29912429d400f0c48591acadad6d7.1255380039.git.trast@student.ethz.ch> URL: https://gitlist.dev/e/1c524798bde29912429d400f0c48591acadad6d7.1255380039.git.trast%40student.ethz.ch In-Reply-To: ``` We'll use the same output in an upcoming commit, so refactor its formatting (which was duplicated anyway) into a separate function.

Yes, it's arbitrary, though it is probably a reasonable estimate for the intended use of stash. It's a stack, so you generally are only interested in the last couple of entries. What's much worse though is that the logic is not "if you told me how many to show, show that; otherwise, show 10". Instead it is "if you gave me no options, default the size of the list. But if you gave me any options, even if they have nothing whatsoever to do with limiting the size of the list, then show all". So something like "git stash list --date=relative" suddenly shows many more stashes than just "git stash list". It would be nice to fix that. > So suppose we could somehow get rid of the |sed... like if we had > --pretty specifiers for the reflog information. I'm not sure if people will like having a longer list in a pager than a shorter list without one (I personally can't remember ever using "git stash list", so I have no strong opinion). But certainly the idea of adding pretty format specifiers to access reflog data seems like a good idea on its own. -Peff ``` ## Thomas Rast, 2009-10-12 21:52 Subject: Re: [RFC PATCH 0/5] Pretty formats for reflog data Message-ID: <200910122352.25658.trast@student.ethz.ch> URL: https://gitlist.dev/e/200910122352.25658.trast%40student.ethz.ch In-Reply-To: <20091012213756.GA12166@coredump.intra.peff.net> ``` Jeff King wrote: > > I'm not sure if people will like having a longer [stash] list in a > pager than a shorter list without one (I personally can't remember > ever using "git stash list", so I have no strong opinion).

Then again we patched git-stash(1) to recommend stash/pop over stash/apply, so we should actively show the user that s/he has a long stash list and may want to apply them somewhere. -- Thomas Rast trast@{inf,student}.ethz.ch ``` ## Jeff King, 2009-10-14 04:59 Subject: Re: [RFC PATCH 2/5] Introduce new pretty formats %g and %G for reflog information Message-ID: <20091014045918.GA31810@coredump.intra.peff.net> URL: https://gitlist.dev/e/20091014045918.GA31810%40coredump.intra.peff.net In-Reply-To: ``` On Mon, Oct 12, 2009 at 11:06:04PM +0200, Thomas Rast wrote: > Unfortunately, we also need to pass down the reflog_walk_info from > show_log(), so this commit touches a lot of (unrelated) callers to > pretty_print_commit() and format_commit_message() to accomodate the > extra argument. A while back I wanted to add a feature to pretty-printing, and I ran into the same situation (though my feature never made it to the list). We really end up passing around the same arguments over and over. Maybe it makes sense instead of adding another argument to refactor into a "pretty_print_context" struct that contains all of the arguments and current state. It would be an even more invasive patch, but I think it would make things more readable, and make future changes much easier to see. -Peff ``` ## Jeff King, 2009-10-14 05:00 Subject: Re: [RFC PATCH 3/5] stash: Use new %g/%G formats instead of sed Message-ID: <20091014050038.GB31810@coredump.intra.peff.net> URL: https://gitlist.dev/e/20091014050038.GB31810%40coredump.intra.peff.net In-Reply-To: <77e591b80021efc265fea1a101ce6b7124ea832e.1255380039.git.trast@student.ethz.ch> ``` On Mon, Oct 12, 2009 at 11:06:05PM +0200, Thomas Rast wrote: > list_stash () { > have_stash || return 0 > - git log --no-color --pretty=oneline -g "$@" $ref_stash -- | > - sed -n -e 's/^[.0-9a-f]* refs\///p' > + git log --format="%g: %G" -g "$@" $ref_stash You dropped the trailing "--" which is needed for disambiguation. -Peff ``` ## Jeff King, 2009-10-14 05:02 Subject: Re: [RFC PATCH 4/5] stash list: drop the default limit of 10 stashes Message-ID: <20091014050248.GC31810@coredump.intra.peff.net> URL: https://gitlist.dev/e/20091014050248.GC31810%40coredump.intra.peff.net In-Reply-To: <137df1f7295576345f5aefe46c882399e107c321.1255380039.git.trast@student.ethz.ch> ``` On Mon, Oct 12, 2009 at 11:06:06PM +0200, Thomas Rast wrote: > 'git stash list' had an undocumented limit of 10 stashes, unless other > git-log arguments were specified.

Having slept on it, I think I agree that this is a good change. It fixes the ugly corner cases I mentioned, and it is easier to explain. -Peff ``` ## Jeff King, 2009-10-14 05:06 Subject: Re: [RFC PATCH 5/5] stash: change built-in ref to 'stash' instead of 'refs/stash' Message-ID: <20091014050645.GD31810@coredump.intra.peff.net> URL: https://gitlist.dev/e/20091014050645.GD31810%40coredump.intra.peff.net In-Reply-To: <548bc3a41c03a049e782d5d04a34c3b26c0897d2.1255380039.git.trast@student.ethz.ch> ``` On Mon, Oct 12, 2009 at 11:06:07PM +0200, Thomas Rast wrote: > 'git stash list' now always shows 'refs/stash@{...}' instead of > 'stash@{...}', because that's what we specify for the ref. > > Since git checks .git/$ref, .git/refs/$ref and only then > .git/refs/{branches,tags,remotes}, we can drop the prefix.

Maybe a better solution would be a "short name" variant for pretty format specifiers. We already have %(refname) and %(refname:short) in for-each-ref, where the latter cuts off "refs/heads/", "refs/tags", or "refs/remotes/" from the beginning. I'm not sure if it does just "refs/", but probably it should. It may even check for ambiguity, but I'd have to double-check the code. The tricky part would be deciding on a syntax. This seems to come up a fair bit. I think there is room for somebody to suggest a more expansive --format syntax that can handle arbitrary arguments being given to expansions (I think there was some discussion recently in a related thread about body indentation, but I haven't been following it too closely). -Peff ``` ## Junio C Hamano, 2009-10-14 09:13 Subject: Re: [RFC PATCH 2/5] Introduce new pretty formats %g and %G for reflog information Message-ID: <7vd44qfidi.fsf@alter.siamese.dyndns.org> URL: https://gitlist.dev/e/7vd44qfidi.fsf%40alter.siamese.dyndns.org In-Reply-To: ``` Squash this patch on top, as cc1: warnings being treated as errors reflog-walk.c: In function 'get_reflog_message': reflog-walk.c:278: error: ISO C90 forbids mixed declarations and code --- reflog-walk.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/reflog-walk.c b/reflog-walk.c index 929f025..5cbcb1a 100644 --- a/reflog-walk.c +++ b/reflog-walk.c @@ -270,12 +270,13 @@ void get_reflog_message(struct strbuf *sb, { struct commit_reflog *commit_reflog = reflog_info->last_commit_reflog; struct reflog_info *info; + size_t len; if (!commit_reflog) return; info = &commit_reflog->reflogs->items[commit_reflog->recno+1]; - size_t len = strlen(info->message); + len = strlen(info->message); if (len > 0) len--; strbuf_add(sb, info->message, len); ``` ## Thomas Rast, 2009-10-14 09:58 Subject: Re: [RFC PATCH 2/5] Introduce new pretty formats %g and %G for reflog information Message-ID: <200910141158.35050.trast@student.ethz.ch> URL: https://gitlist.dev/e/200910141158.35050.trast%40student.ethz.ch In-Reply-To: <20091014045918.GA31810@coredump.intra.peff.net> ``` Jeff King wrote: > On Mon, Oct 12, 2009 at 11:06:04PM +0200, Thomas Rast wrote: > > > Unfortunately, we also need to pass down the reflog_walk_info from > > show_log(), so this commit touches a lot of (unrelated) callers to > > pretty_print_commit() and format_commit_message() to accomodate the > > extra argument. > > A while back I wanted to add a feature to pretty-printing, and I ran > into the same situation (though my feature never made it to the list). > We really end up passing around the same arguments over and over.
