Well, that depends on how you look at it. -m and --merge are (sort of) mutually
exclusive, as the use of one voids the use of the other.
Likewise, using -a and -A together on the same command-line doesn't make much
sense (although -A implies -a rather than meaning the same thing).

I guess such a backend would be useful for StGit as well.

I suspect that you need something like

len = strlen(p->pack_name);

I actually started to write such a command this weekend, but I didn't
have time to finish it. I did however come to the conclusion that I'd
want to refactor the relationship between patches and commits first.
(Which was why I was so pleasantly surprised that you spent part of

In-Reply-To: <1190017633436-git-send-email-gitster@pobox.com>
Deciding to run "repack -d -l" when there are too many
loose objects would backfire when there are too many loose
objects that are unreachable, because repacking that way would
never improve the situation. Detect that case by checking the
number of loose objects again after automatic garbage collection
runs, and issue an warning to run "prune" manually.

* [PATCH 0/8] Updated git-gc --auto series.
From: Junio C Hamano @ 2007-09-17 8:27 UTC (permalink / raw)
To: git
An updated series of "git-gc --auto", on top of 'next',
consisting of 8 patches, will follow this message.
Differences from the previous round are:
- Earlier if you have too many unreachable loose objects,
automated gc would have tried to "repack -d -l" which would
not improve the situation at all every time it was run. It
now at least warns upon such a situation;
- pack-objects learned --keep-unreachable option which helps
"repack -a -d" not to lose packed but unreachable objects
while repacking existing packs into a new pack;
- repack learned -A option which is similar to -a but gives
--keep-unreachable to underlying pack-objects;
- "git-gc --auto" runs "git-repack -A -d -l" when there are too
many packs in the repository;
- These changes are documented ;-)

unreachable objects that are in packs.

This teaches "git-gc --auto" to consolidate many packs into one
without losing unreachable objects in them by using "repack -A"
when there are too many packfiles that are not marked with *.keep
in the repository. gc.autopacklimit configuration can be used
to set the maximum number of packs a repository is allowed to
have before this mechanism kicks in.

The function sounds boolean; make it behave as one, not "0 for
success, non-zero for failure".

* [PATCH 2/8] pack-objects --keep-unreachable
From: Junio C Hamano @ 2007-09-17 8:27 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano
In-Reply-To: <1190017633436-git-send-email-gitster@pobox.com>
This new option is meant to be used in conjunction with the
options "git repack -a -d" usually invokes the underlying
pack-objects. When this option is given, objects unreachable
from the refs in packs named with --unpacked= option are added
to the resulting pack, in addition to the reachable objects that
are not in packs marked with *.keep files.

This subtly changes behaviour: --auto ran also garbage collection for

This might be intended, but is not documented.

Just to add.
If i pull tags with
$git-pull ssh://user1@10.100.205.34/opt/test/project test
i get them.
doing a git-merge v-1.0b does not reflect any changes but a git-branch
new_test v-1.0b makes new_test branch which has the changes.
Again git-merge new_test fails miserably, it says no conflicts though
there are conflicts.
What is happening here? :-/
I am puzzled.
Can anybody please help me???
thanks

It might strike a newbie as dangerous to read "prune them" here. Maybe
... `git gc --auto` will pack the loose objects. Some Porcelain
commands use this command, to do a light weight garbage collection
from time to time.
+
*Note*: you should still run "git gc" from time to time, since the
"--auto" option is designed to be fast, whereas "git gc" _without_
auto is designed to create small packs.
Hmm? (I think that this is the most visible part of the --auto business,
so I would document the "git gc" note here...)

Would "[-a] [-A]" not be better? In other usage lines, we have the "|"

Why not "keep_unreachable=--keep-unreachable" and use "$args
$keep_unreachable" later?

The real problem is that we use "commit" in two senses:
- the action ("to commit", but also, "to do a commit") of making a new
revision, but also
- the revision in the revision graph ("is this in the commit abcdef?").
So I do not think that any proposals reflect the ambiguity of "a commit".
I actually talk about "Revision" in German, when I refer to a commit.

I am using git at work for a rather big repository. Size is around
1.5-1.8Gigs now.
My git version is 1.5.2.4.
The remote repo has some changes to a file with some simple printk's
some some code changes.
I have my git repo in /mnt/reiser/project .
I changed to the my repo.
i did a git-pull ssh://user1@10.100.205.34/opt/test/project test .[to
pull from another test machine].
I got some conflicts in a file but in some important files it did not update it.
Any hints whats wrong with my technique or is there something wrong with git?
BTW the two machines have different versions of git. The remote
machine have git-1.4.4 from ubuntu repo.

This teaches "git-gc --auto" to consolidate many packs into one
without losing unreachable objects in them by using "repack -A"
when there are too many packfiles that are not marked with *.keep
in the repository. gc.autopacklimit configuration can be used
to set the maximum number of packs a repository is allowed to
have before this mechanism kicks in.

Deciding to run "repack -d -l" when there are too many
loose objects would backfire when there are too many loose
objects that are unreachable, because repacking that way would
never improve the situation. Detect that case by checking the
number of loose objects again after automatic garbage collection
runs, and issue an warning to run "prune" manually.

* [PATCH 7/8] git-gc --auto: restructure the way "repack" command line is built.
From: Junio C Hamano @ 2007-09-17 8:44 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano
In-Reply-To: <11900186941912-git-send-email-gitster@pobox.com>
We used to build the command line to run repack outside of
need_to_gc() but with the next patch we would want to tweak the
command line depending on the nature of need.

That is where we decide if we are going to run gc
automatically.

+ With this option, `git gc` checks if there are too many
