What's cooking in git.git (Sep 2010, #01; Wed, 1)

What's cooking in git.git (Sep 2010, #01; Wed, 1)

[Junio C Hamano]

Here are the topics that have been cooking.  Commits prefixed with '-' are
only in 'pu' while commits prefixed with '+' are in 'next'.  The ones
marked with '.' do not appear in any of the integration branches, but I am
still holding onto them.

As I didn't want to worry about the early parts of ab/i18n topic, which
was accidentally merged to 'next' due to my lazyness (another topic,
ab/test, seemed to be ready for the upcoming release, but a patch to that
topic had interaction with ab/i18n, which made ab/test unmergeable to
'master' without dragging 'ab/i18n'), I reverted ab/i18n topic from 'next'
and merged a rebuilt ab/test topic to 'next'.  The i18n topic is merged
to 'pu'.

I am hoping to tag -rc0 for the 1.7.3 release this weekend.

As I'd like to have this in the upcoming release, the tip of old ab/test
topic has been rebuilt without the merge from ab/i18n topic.

* as/daemon-multi-listen (2010-08-29) 2 commits
 - daemon: allow more than one host address given via --listen
 - daemon: add helper function setup_named_sock()

I think the idea is sound.  It came a bit late in the cycle for the next
release and probably needs a bit more polish.

* jc/pickaxe-grep (2010-08-31) 4 commits
 - diff/log -G<pattern>: tests
 - git log/diff: add -G<regexp> that greps in the patch text
 - diff: pass the entire diff-options to diffcore_pickaxe()
 - gitdiffcore doc: update pickaxe description

This is a re-roll of "grepping inside the log -p output" which is a
feature that is often asked for when people hear about -S option.

* jh/error-removing-missing-note (2010-08-31) 1 commit
 - notes: Don't create (empty) commit when removing non-existing notes

Should be Ok to merge to 'next'; then will merge to 'master' shortly.

 - tests: make test_might_fail fail on missing commands
 - tests: make test_might_fail more verbose
 - tests: make test_must_fail fail on missing commands
 - tests: make test_must_fail more verbose

Should be Ok to merge to 'next'; then will merge to 'master' shortly.

* jl/fetch-submodule-recursive (2010-08-30) 2 commits
 - Submodules: Add the new "fetch" config option for fetch and pull
 - fetch/pull: Recursively fetch populated submodules

I think the idea is sound and hopefully the end result will help the heavy
users of subprojects.  It came a bit late in the cycle for the next
release, though.

* kf/askpass-config (2010-08-30) 3 commits
 - Extend documentation of core.askpass and GIT_ASKPASS.
 - Allow core.askpass to override SSH_ASKPASS.
 - Add a new option 'core.askpass'.

Should be Ok to merge to 'next'; then will merge to 'master' shortly.

* tf/churn (2010-09-01) 2 commits
 - help.c: Pull cmd_version out of this file.
 - builtin.h: Move two functions definitions to help.h.

I don't like churning-for-the-sake-of-churning like these patches that
does not solve real problems and instead adds potential new ones.

At this point, adding the dashed-form "git-version" to the filesystem is
going backwards.  These files are only to help people who have old scripts
from pre 1.6.0 days with "PATH=$(git --exec-path):$PATH" with their
environment.

We should instead try to not adding them (which would probably need tweak
in the command list generation code in "git help"), as nobody from pre
1.6.0 era would have called "git-version" binary.

documentation nor tests).

* zl/mailinfo-recode-patch (2010-06-14) 2 commits
 - add --recode-patch option to git-am
 - add --recode-patch option to git-mailinfo

I recall there was another round of re-roll planned for this one.

* jk/tag-contains (2010-07-05) 4 commits
 - Why is "git tag --contains" so slow?
 - default core.clockskew variable to one day
 - limit "contains" traversals based on commit timestamp
 - tag: speed up --contains calculation

The idea of the bottom one is probably Ok, except that the use of object
flags needs to be rethought, or at least the helper needs to be moved to
builtin/tag.c to make it clear that it should not be used outside the
current usage context.

* cb/ignored-paths-are-precious (2010-08-21) 1 commit
 - checkout/merge: optionally fail operation when ignored files need to be overwritten

I fixed up a trivial error in the configuration parser (which didn't
return immediately after parsing), and while at it flipped the default 
value of the configuration and the command line option to false.

This probably needs tests; also we know of longstanding bugs in related
area that needs to be addressed---they do not have to be part of this
series but their reproduction recipe would belong to the test script for
this topic.

It may hurt users to make the new feature on by default, especially the
ones with subdirectories that come and go.  For a patch that changes a
long established semantics, it came a bit late in the cycle, so it will
have to wait until the next release.

Cool, whatever makes release engineering easy for you. But the
"gettext: Make NO_GETTEXT=YesPlease the default in releases"
monkeypatch should probably be ejected out of pu.

I only wrote it in case gettext wouldn't be ejected from next and
would make it into 1.7.3, but since that won't be the case there's
really no reason for it to exist anywhere but the mailing list
archive.

It's also broken as a proper way to disable gettext (in case we want
to go that route). There's no way to re-enable it if you use the
./configure script.

It's really only a monkeypatch.

Thanks, and sorry for tangling them up.

Is this facility also used for the smtp password promt in

We're going to have to get this working on non-GNU if it's to make it
into 1.7.3. I can probably help with that if jj doesn't have time.

I'll try to recall to get these patches we have on top of it into
gawk/glibc once it's settled a bit more.

Are you possibly remembering v1 of the series, which mis-used the
tree_entry_interesting() API, and was fixed by v2 including extra
testcases?  You merged the latter into pu, so there's no remaining
issue I know of.

However, if I've missed some email or other report about any other
breakage, let me know and I'll take a look.

I agree, both this and the en/object-list-with-pathspec series
probably make sense to wait for 1.7.4.

I haven't really used it recently since I'm redoing my series to
support multiple subtree. Will let you know soon if it works (v2
worked last time before the rework).

While at there, how about adding tree exclusion mechanism that you
mentioned in sparse clone? That would be really cool.

/me is happy, pu contains the last version of the patch, with the test
and without the bugs ;-).

I'm fine with delaying this after the release.

Right about me misremembering things; thanks.

Tree exclusion or commit exclusion?  I think I have the former working
(I'll post a patch series soon), but not the latter yet.

Yeah.. I'm looking at it now. By tree exclusion, I meant negative
pathspec. Something like "traverse anything in 't' except t/t9700". I
can see you are getting real close to that.

Ah, nope, I haven't tackled that at all and hadn't planned to anytime soon.
