Document pack .idx file format upgrade strategy.

Way back when Junio developed the 64 bit index topic he came up
with a means of changing the .idx file format so that older Git
clients would recognize that they don't understand the file and
refuse to read it, while newer clients could tell the difference
between the old-style and new-style .idx files.  Unfortunately
this wasn't recorded anywhere.

This change documents how we might go about changing the .idx
file format by using a special signature in the first four bytes.
Credit (and possible blame) goes completely to Junio for thinking
up this technique.

The change also modifies the error message of the current Git code
so that users get a recommendation to upgrade their Git software
should this version or later encounter a new-style .idx which it
cannot process.  We already do this for the .pack files, but since
we usually process the .idx files first its important that these
files are recognized and encourage an upgrade.

Correct priority of lightweight tags in git-describe.

We really want to always favor an annotated tag over a lightweight

doing this as it was favoring the depth attribute of a possible_tag

consider a lightweight tag if no annotated tags were identified.

Rather than searching for the minimum tag using a simple loop we
now sort them using a stable sort algorithm, this way the possible
tags display in order if --debug gets used.  The stable sort helps

Shawn O. Pearce [Sat, 13 Jan 2007 22:30:53 +0000 (17:30 -0500)]
Improve git-describe performance by reducing revision listing.

My prior version of git-describe ran very slowly on even reasonably
sized projects like git.git and linux.git as it tended to identify
a large number of possible tags and then needed to generate the
revision list for each of those tags to sort them and select the
best tag to describe the input commit.

All we really need is the number of commits in the input revision
which are not in the tag.  We can generate these counts during
the revision walking and tag matching loop by assigning a color to
each tag and coloring the commits as we walk them.  This limits us
to identifying no more than 26 possible tags, as there is limited
space available within the flags field of struct commit.

The limitation of 26 possible tags is hopefully not going to be a
problem in real usage, as most projects won't create 26 maintenance
releases and merge them back into a development trunk after the
development trunk was tagged with a release candidate tag.  If that
does occur git-describe will start to revert to its old behavior of
using the newer maintenance release tag to describe the development
trunk, rather than the development trunk's own tag.  The suggested
workaround would be to retag the development trunk's tip.

However since even 26 possible tags can take a while to generate a
description for on some projects I'm defaulting the limit to 10 but
offering the user --candidates to increase the number of possible
matches if they need a more accurate result.  I specifically chose
10 for the default as it seems unlikely projects will have more
than 10 maintenance releases merged into a development trunk before
retagging the development trunk, and it seems to perform about the
same on linux.git as v1.4.4.4 git-describe.

A large amount of debugging information was also added during
the development of this change, so I've left it in to be toggled
on with --debug.  It may be useful to the end user to help them
understand why git-describe took one particular tag over another.

a large amount of time if done repeatedly during history traversal.

Since we are searching for a unique commit SHA1 we can sort all
tags by commit SHA1 and perform a binary search within the bucket.
Once we identify a particular tag as matching this commit we walk
backwards within the bucket matches to make sure we pick up the
highest priority tag for that commit, as the binary search may

Allow whole-tree operations to be started from a subdirectory

This updates five commands (merge, pull, rebase, revert and cherry-pick)
so that they can be started from a subdirectory.

This may not actually be what we want to do.  These commands are
inherently whole-tree operations, and an inexperienced user may
mistakenly expect a "git pull" from a subdirectory would merge
only the subdirectory the command started from.

happens, including for the disk full case), a lot of the callers of
write_in_full() were just unnecessarily complex.

In particular, there's no reason to ever check for a zero length or
return: if the length was zero, we'll return zero, otherwise, if a disk
full resulted in the actual write() system call returning zero the
write_in_full() logic would have correctly turned that into a negative
return value, with 'errno' set to ENOSPC.

17 years agoChose better tag names in git-describe after merges.
Shawn O. Pearce [Wed, 10 Jan 2007 11:39:47 +0000 (06:39 -0500)]
Chose better tag names in git-describe after merges.

Recently git.git itself encountered a situation on its master and
next branches where git-describe stopped reporting 'v1.5.0-rc0-gN'
and instead started reporting 'v1.4.4.4-gN'.  This appeared to be
a backward jump in version numbering.

  maint     o-------------------4
            \                    \
  master     o-o-o-o-o-o-o-5-o-C-o-W

The issue is that commit C in the diagram claims it is version
1.5.0, as the tag v1.5.0 is placed on commit 5.  Yet commit W
claims it is version 1.4.4.4 as the tag v1.5.0 has an older tag
date than the v1.4.4.4 tag.

As it turns out this situation is very common.  A bug fix applied
to maint and later merged into master occurs frequently enough that
it should Just Work Right(tm).

Rather than taking the first tag that gets found git-describe will
now generate a list of all possible tags and select the one which
has the most number of commits in common with HEAD (or whatever
revision the user requested the description of).

This rule is based on the principle shown in the diagram above.
There are a large number of commits on the primary development branch
'master' which do not appear in the 'maint' branch, and many of
these are already tagged as part of v1.5.0-rc0.  Additionally these
commits are not in v1.4.4.4, as they are part of the v1.5.0 release
still being developed.  The v1.5.0-rc0 tag is more descriptive of
W than v1.4.4.4 is, and therefore should be used.
