Commit e4c72923 (write_entry(): use fstat() instead of lstat() when file
is open, 2009-02-09) introduced an optimization of write_entry().
Unfortunately, we cannot take advantage of this optimization on Windows
because there is no guarantee that the time stamps are updated before the
file is closed:

  "The only guarantee about a file timestamp is that the file time is
   correctly reflected when the handle that makes the change is closed."

(http://msdn.microsoft.com/en-us/library/ms724290(VS.85).aspx)

The failure of this optimization on Windows can be observed most easily by
running a 'git checkout' that has to update several large files. In this
case, 'git checkout' will report modified files, but infact only the
timestamps were incorrectly recorded in the index, as can be verified by a
subsequent 'git diff', which shows no change.

An earlier commit aab3b9a (read-tree A B C: do not create a bogus index

(but useful) feature to read and overlay more than one tree into the index
without the -m (merge) option.  But the fix was not enough.

Exercising this feature exposes a longstanding bug in the code that primes
the cache-tree in the index from the tree that was read.  The intention
was that when we know that the index must exactly match the tree we just
read, we prime the entire cache-tree with it.

However, the logic to detect that case incorrectly triggered if you read
two trees without -m.  This resulted in a corrupted cache-tree, and
write-tree would have produced an incorrect tree object out of such an

Johannes Sixt [Fri, 3 Apr 2009 06:49:59 +0000 (08:49 +0200)]
Windows: Work around intermittent failures in mingw_rename

We have replaced rename() with a version that can rename a file to a
destination that already exists. Nevertheless, many users, the author
included, observe failures in the code that are not reproducible.

The theory is that the failures are due to some other process that happens
to have opened the destination file briefly at the wrong moment. (And there
is no way on Windows to delete or replace a file that is currently open.)
The most likely candidate for such a process is a virus scanner. The
failure is more often observed while there is heavy git activity (for
example while the test suite is running or during a rebase operation).

We work around the failure by retrying the rename operation if it failed
due to ERROR_ACCESS_DENIED. The retries are delayed a bit: The first only
by giving up the time slice, the next after the minimal scheduling
granularity, and if more retries are needed, then we wait some non-trivial
amount of time with exponential back-off.

15 years agoadd-interactive: refactor mode hunk handling
Jeff King [Thu, 16 Apr 2009 07:14:15 +0000 (03:14 -0400)]
add-interactive: refactor mode hunk handling

The original implementation considered the mode separately
from the rest of the hunks, asking about it outside the main
hunk-selection loop. This patch instead places a mode change
as the first hunk in the loop. This has two advantages:

  1. less duplicated code (since we use the main selection
     loop). This also cleans up an inconsistency, which is
     that the main selection loop separates options with a
     comma, whereas the mode prompt used slashes.

  2. users can now skip the mode change and come back to it,
     search for it (via "/mode"), etc, as they can with other
     hunks.

To facilitate this, each hunk is now marked with a "type".
Mode hunks are not considered for splitting (which would
make no sense, and also confuses the split_hunk function),
nor are they editable. In theory, one could edit the mode
lines and change to a new mode. In practice, there are only
two modes that git cares about (0644 and 0755), so either
you want to move from one to the other or not (and you can
do that by staging or not staging).
