That's not the issue. I didn't install that update until later.
I remember because I installed it just before I transferred
everything to my new hard drive with dd_rescue.
Still trying to understand what you are encountering.
Here's the summary. /usr/bin/rsync was passing my test suite, then
it suddenly started failing. There was no reboot, no system update,
no configuration change that would explain this. Here's my svn
commit message:
"""
Make sure that disks have owners enabled before copying.
Add subtests for ACLs on dirs and symlinks.
This is so weird. At some point tonight I started seeing the rsync/
tarpipe
failures that I saw when trying to do my backups. I was trying to
trigger these
failures intentionally and having no luck, then suddenly - POW. Now
I can't get
them to stop! I've tried using fresh disk images and reverting to older
revisions of the code, but nothing seems to work. I haven't tried
rebooting
yet, but I probably should.
"""
I re-read your previous post several times.
For example, you wrote: "I booted from the Tiger install DVD,
mounted both my drives, and started my copy, being sure to use the
path to the up-to-date rsync on my system drive. The result? My
copy was a disaster."
What's the OS version on that DVD?
10.4.0 presumably, since it was bought the day Tiger was released.
You also wrote: "BB tests copying from a volume with ACLs enabled
to another volume where they're enabled. However, as I mentioned,
I realized that they're *not* enabled on my root volume, so I
tried disabling them on my BB source volume. Nothing happened --
the tests still passed. However, it was soon thereafter that they
failed (within an hour or so)."
Could you try to see which OS version as well as which updates (if
any) were installed on your laptop at that time?
Ok. As I said, the tests started failing on 4/24. Here's the tail
of my software update log:
2007-03-14 12:08:14 -0700: Installed "Mac OS X Update
(PowerPC)" (10.4.9)
2007-03-31 21:16:10 -0700: Installed "iTunes" (7.1.1)
2007-04-22 23:43:29 -0700: Installed "Security Update 2007-004
(PowerPC)" (1.0)
2007-05-02 14:06:55 -0700: Installed "QuickTime" (7.1.6)
I guess I was somewhat mistaken about the chronology -- I installed
the update just before my *first* backup attempt (the one that
failed). But you can see there was no update on 4/24.
Anyway, other people tend to relate the problem to Security Update
2007-004 (v1.0 as well as v1.1) too.
Could you have a look at:
<http://lists.apple.com/archives/macos-x-server/2007/May//
msg00040.html>
and subsequent messages?
If it's related to SU2007-4 it's a very strange correlation. I was
testing for 2 days after that update before the "change" happened.
