gitk: Fix "wrong # coordinates" error on reload

This fixes the Tk error "wrong # coordinates: expected 0 or 4, got 2"
that sometimes occurred when reloading.  The problem was that we didn't
unset the variables containing the canvas item id numbers for the
displayed rows when we cleared the canvases.  Thus make_secsel would
think it had something to do when it didn't.

Nicolas Pitre [Wed, 14 May 2008 05:33:53 +0000 (01:33 -0400)]
let pack-objects do the writing of unreachable objects as loose objects

Commit ccc1297226b184c40459e9d373cc9eebfb7bd898 changed the behavior
of 'git repack -A' so unreachable objects are stored as loose objects.
However it did so in a naive and inn efficient way by making packs
about to be deleted inaccessible and feeding their content through
'git unpack-objects'.  While this works, there are major flaws with
this approach:

- It is unacceptably sloooooooooooooow.

  In the Linux kernel repository with no actual unreachable objects,
  doing 'git repack -A -d' before:

real    2m33.220s
user    2m21.675s
sys     0m3.510s

  And with this change:

real    0m36.849s
user    0m24.365s
sys     0m1.950s

  For reference, here's the timing for 'git repack -a -d':

real    0m35.816s
user    0m22.571s
sys     0m2.011s

  This is explained by the fact that 'git unpack-objects' was used to
  unpack _every_ objects even if (almost) 100% of them were thrown away.

- There is a black out period.

  Between the removal of the .idx file for the redundant pack and the
  completion of its unpacking, the unreachable objects become completely
  unaccessible.  This is not a big issue as we're talking about unreachable
  objects, but some consistency is always good.

- There is no way to easily set a sensible mtime for the newly created
  unreachable loose objects.

So, while having a command called "pack-objects" to perform object
unpacking looks really odd, this is probably the best compromize to be
able to solve the above issues in an efficient way.

filter-branch: fix variable export logic

filter-branch tries to restore "old" copies of some
environment variables by using the construct:

  unset var
  test -z "$old_var" || var="$old_var" && export var

This is just wrong.  AND-list and OR-list operators && and || have equal
precedence and they bind left to right.  The second term, var="$old"
assignment always succeeds, so we always end up exporting var.

On bash and dash, exporting an unset variable has no effect. However, on
some shells (such as FreeBSD's /bin/sh), the shell exports the empty
value.

This manifested itself in this case as git-filter-branch setting
GIT_INDEX_FILE to the empty string, which in turn caused its call to
git-read-tree to fail, leaving the working tree pointing at the original
HEAD instead of the rewritten one.

To fix this, we change the short-circuit logic to better match the intent:

  test -z "$old_var" || {
    var="$old_var" && export var
  }

repack: modify behavior of -A option to leave unreferenced objects unpacked

The previous behavior of the -A option was to retain any previously
packed objects which had become unreferenced, and place them into the newly
created pack file.  Since git-gc, when run automatically with the --auto
option, calls repack with the -A option, this had the effect of retaining
unreferenced packed objects indefinitely. To avoid this scenario, the
user was required to run git-gc with the little known --prune option or
to manually run repack with the -a option.

This patch changes the behavior of the -A option so that unreferenced
objects that exist in any pack file being replaced, will be unpacked into
the repository. The unreferenced loose objects can then be garbage collected
by git-gc (i.e. git-prune) based on the gc.pruneExpire setting.

Also add new tests for checking whether unreferenced objects which were
previously packed are properly left in the repository unpacked after
repacking.
