Description Mark McLoughlin 2004-05-20 03:32:29 EDT
With a directory hierarchy in which a number of files had been
deleted, I found this crashed:

$> rsync -avrz -pot -e ssh --delete --existing
markmc@* .

This is a fresh install of FC2 - rsync-2.6.2-0. Attaching a backtrace.

I've kept a copy of the directory hierarchy causing the crash, but I
haven't found a simple isolated test case yet.

Comment 2 Mark McLoughlin 2004-05-20 05:13:01 EDT
Test case:

mkdir /tmp/sync-from
mkdir /tmp/sync-from/test1
mkdir /tmp/sync-from/test2
> /tmp/sync-from/test1/a
> /tmp/sync-from/test2/a
mkdir /tmp/sync-to
cd /tmp/sync-to
rsync -av --delete localhost:/tmp/sync-from/* .
rsync -av --delete localhost:/tmp/sync-from/* .

Problem is that we rebuild the file_list for each of test1 and test2,
but "lastdir" in make_file() still points to the freed file_list of test1.

Attaching a patch that invalidates lastdir when freeing the file_list.

I've checked upstream and the bug is fixed there with a simpler fix.
Attaching a backport.
