1701409003 git-config: Improve documentation of git-config file handling
The description which files git-config uses and how the various

f7c22cc68c always start looking up objects in the last used pack first
Jon Smirl said:

| Once an object reference hits a pack file it is very likely that
| following references will hit the same pack file. So first place to
| look for an object is the same place the previous object was found.

This is indeed a good heuristic so here it is.  The search always start
with the pack where the last object lookup succeeded.  If the wanted
object is not available there then the search continues with the normal
pack ordering.

To test this I split the Linux repository into 66 packs and performed a
"time git-rev-list --objects --all > /dev/null".  Best results are as
follows:

	Pack Sort			w/o this patch	w/ this patch
	-------------------------------------------------------------
	recent objects last		26.4s		20.9s
	recent objects first		24.9s		18.4s

This shows that the pack order based on object age has some influence,
but that the last-used-pack heuristic is even more significant in
reducing object lookup.

Signed-off-by: Nicolas Pitre <nico@cam.org> --- Note: the
--max-pack-size to git-repack currently produces packs with old objects
after those containing recent objects.  The pack sort based on
filesystem timestamp is therefore backward for those.  This needs to be
fixed of course, but at least it made me think about this variable for
the test.

5476a8adcc fix repack with --max-pack-size
Two issues here:

1) git-repack -a --max-pack-size=10 on the GIT repo dies pretty quick.
   There is a lot of confusion about deltas that were suposed to be
   reused from another pack but that get stored undeltified due to pack
   limit and object size doesn't match entry->size anymore.  This test
   is not really worth the complexity for determining when it is valid
   so get rid of it.

2) If pack limit is reached, the object buffer is freed, including when
   it comes from a cached delta data.  In practice the object will be
   stored in a subsequent pack undeltified, but let's make sure no
   pointer to freed data subsists by clearing entry->delta_data.

I also reorganized that code a bit to make it more readable.

b77ffe8a57 Ensure the pack index is opened before access
In this particular location of fsck the index should have already
been opened by verify_pack, which is called just before we get
here and loop through the object names.  However, just in case a

eaa8677039 Simplify index access condition in count-objects, pack-redundant
My earlier lazy index opening patch changed this condition to check
index_data and call open_pack_index if it was NULL. In truth we only
care about num_objects.  Since open_pack_index does no harm if the
index is already open, and all indexes are likely to be closed in
this application, the "performance optimization" of inlining the
index_data check here was wrong.

7ff895c0d2 Test for recent rev-parse $abbrev_sha1 regression
My recent patch "Lazily open pack index files on demand" caused a
regression in the case of parsing abbreviated SHA-1 object names.
Git was unable to translate the abbreviated name into the full name
if the object was packed, as the pack .idx files were not opened
before being accessed.

This is a simple test to repack a repository then test for an
abbreviated SHA-1 within the packfile.

074b2eea29 git-pack-objects: cache small deltas between big objects
Creating deltas between big blobs is a CPU and memory intensive task.
In the writing phase, all (not reused) deltas are redone.

This patch adds support for caching deltas from the deltifing phase, so
that that the writing phase is faster.

The caching is limited to small deltas to avoid increasing memory usage very much.
The implemented limit is (memory needed to create the delta)/1024.

2e4aef5893 Allow contrib new-workdir to link into bare repositories
On one particular system I like to keep a cluster of bare Git
repositories and spawn new-workdirs off of them.  Since the bare
repositories don't have working directories associated with them
they don't have a .git/ subdirectory that hosts the repository we
are linking to.

Using a bare repository as the backing repository for a workdir
created by this script does require that the user delete core.bare
from the repository's configuration file, so that Git auto-senses
the bareness of a repository based on pathname information, and
not based on the config file.

aa252f194b git-gui: Allow users to delete remote branches
Git has supported remote branch deletion for quite some time, but
I've just never gotten around to supporting it in git-gui.  Some
workflows have users push short-term branches to some remote Git
repository, then delete them a few days/weeks later when that topic
has been fully merged into the main trunk.  Typically in that style
of workflow the user will want to remove the branches they created.

We now offer a "Delete..." option in the Push menu, right below the
generic "Push..." option.  When the user opens our generic delete
dialog they can select a preconfigured remote, or enter a random
URL.  We run `git ls-remote $url` to obtain the list of branches and
tags known there, and offer this list in a listbox for the user to
select one or more from.

Like our local branch delete dialog we offer the user a way to filter
their selected branch list down to only those branches that have been
merged into another branch.  This is a very common operation as the
user will likely want to select a range of topic branches, but only
delete them if they have been merged into some sort of common trunk.

Unfortunately our remote merge base detection is not nearly as strict
as the local branch version.  We only offer remote heads as the test
commit (not any local ones) and we require that all necessary commits
to successfully run git-merge-base are available locally.  If one or
more is missing we suggest that the user run a fetch first.

Since the Git remote protocol doesn't let us specify what the tested
commit was when we evaluated our decision to execute the remote delete
there is a race condition here.  The user could do a merge test against
the trunk, determine a topic branch was fully merged, but before they
can start pushing the delete request another user could fast-forward
the remote topic branch to a new commit that is not merged into the
trunk.  The delete will arrive after, and remove the topic, even though
it was not fully merged.

61f82ce79a git-gui: Allow users to rename branches through 'branch -m'
Git's native command line interface has had branch renaming
support for quite a while, through the -m/-M options to the
git-branch command line tool.  This is an extremely useful
feature as users may decide that the name of their current
branch is not an adequate description, or was just entered
incorrectly when it was created.

Even though most people would consider git-branch to be a
Porcelain tool I'm using it here in git-gui as it is the
only code that implements the rather complex set of logic
needed to successfully rename a branch in Git.  Currently
that is along the lines of:

 *) Backup the ref
 *) Backup the reflog
 *) Delete the old ref
 *) Create the new ref
 *) Move the backed up reflog to the new ref
 *) Record the rename event in the reflog
 *) If the current branch was renamed, update HEAD
 *) If HEAD changed, record the rename event in the HEAD reflog
 *) Rename the [branch "$name"] section in the config file

Since that is some rather ugly set of functionality to implement
and get right, and some of it isn't easily accessible through the
raw plumbing layer I'm just cheating by relying on the Porcelain.

clients that typically only use git-gui, and then later have
those branches deleted from the remote repository once they have
been fully merged into all destination branches.  Users of git-gui
would obviously like to have their local tracking branches cleaned
up for them, otherwise their local tracking branch namespace would
grow out of control.

The best known way to remove these tracking branches is to run
"git remote prune <remotename>".  Even though it is more of a
Porcelain command than plumbing I'm invoking it through the UI,
because frankly I don't see a reason to reimplement its ls-remote
output filtering and config file parsing.

A new configuration option (gui.pruneduringfetch) can be used to
automatically enable running "git remote prune <remotename>" after
the fetch of that remote also completes successfully.  This is off
by default as it require an additional network connection and is
not very fast on Cygwin if a large number of tracking branches have
been removed (due to the 2 fork+exec calls per branch).
