git-svn fails in prop_walk if $self->{path} is not empty

If url://repo/trunk is the current Git branch, prop_walk strips trunk
from the path name. That is useful as, for example "git svn show-ignore"
should not return results like

    trunk/foo

but

    foo

if svn:ignore for trunk includes foo.

The problem now is that prop_walk strips trunk from the path and then
calls itself recursively. But now trunk is missing in the path and
get_dir fails, because it is called for a non existing path.

$self->{path} in the recursive call. I tested it with my current

branch switching, because that error return is done before we start to

will be overwritten by branch switching had a mandatory lock on it and we
failed to unlink it.

switching; the files updated in the work tree will hopefully be much more

16 years agobisect: use "$GIT_DIR/BISECT_START" to check if we are bisecting

bisect: use "$GIT_DIR/BISECT_START" to check if we are bisecting

It seems simpler and safer to use the BISECT_START file everywhere
to decide if we are bisecting or not, instead of using it in some
places and BISECT_NAMES in other places.

In commit 6459c7c6786aa9bda0c7a095c9db66c36da0e5f0 (Nov 18 2007,
Bisect: use "$GIT_DIR/BISECT_NAMES" to check if we are bisecting.),
we decided to use BISECT_NAMES but code changed a lot and we now
have to check BISECT_START first in the "bisect_start" function
anyway.

This patch also makes things a little bit safer by creating
the BISECT_START file first and deleting it last, and also by
adding checks in "bisect_clean_state".

Revert "filter-branch: subdirectory filter needs --full-history"

This reverts commit cfabd6eee1745cfec58cfcb794ce8847e43b888a. I had
implemented it without understanding what --full-history does. Consider
this history:

    C--M--N
   /  /  /
  A--B  /
   \   /
    D-/

where B and C modify a path, X, in the same way so that the result is
identical, and D does not modify it at all. With the path limiter X and
without --full-history this is simplified to

   A--B

i.e. only one of the paths via B or C is chosen. I had assumed that
--full-history would keep both paths like this

    C--M
   /  /
  A--B

removing the path via D; but in fact it keeps the entire history.

Currently, git does not have the capability to simplify to this
intermediary case. However, the other extreme to keep the entire history
is not wanted either in usual cases. I think we can expect that histories
like the above are rare, and in the usual cases we want a simplified
history. So let's remove --full-history again.

(Concerning t7003, subsequent tests depend on what the test case sets up,
so we can't just back out the entire test case.)

Fix output of "git log --graph --boundary"

Previously the graphing API wasn't aware of the revs->boundary flag, and
it always assumed that commits marked UNINTERESTING would not be
displayed.  As a result, the boundary commits were printed at the end of
the log output, but they didn't have any branch lines connecting them to
their children in the graph.

There was also another bug in the get_revision() code that caused
graph_update() to be called twice on the first boundary commit.  This
caused the graph API to think that a commit had been skipped, and print
a "..." line in the output.
