Hello everyone,
(Please bear with me, I know this is long, but there is a possible data
loss)
I believe I have suffered a data loss. Recovering the data will be easy,
but I would like to bring this to the attention of the head developers.
I
have suffered this bug because of the Win32 file access race issue. BTW,
is there an issue number for this ? Couldn't find it.
Presently, I use the branch style of development: make changes on
branch,
merge back to trunk. I also saw Subissue here on tigris.org, and I
decided
that it would be nice to try out the ideas, since no code exists.
So, I have the following repository layout:
rac/leadmanagement/
trunk/
branches/
tags/
issues/
assigned/
fbos/
0003/
resolution/
resolved/
(and more)
The resolution/ folder is a copy of trunk/ at r1006.
r1008 was the result of merging the changes from 0003/resolution/ to
trunk/.
The next step was to close the #0003 issue. So, I entered the folder
where
I keep all my issues checked out (WC is rooted at issues/).
Then, I did the following:
svn delete assigned/fbos/0003/resolution
svn move assigned/fbos/0003 resolved
I was bitten quite a few times by the "access denied" problem on
Windows. I had to retry the delete and move two or three times each, all
the
while reverting when the command could not complete.
I finally managed to get my WC to the proper state, and initiated a
commit. Here are the results of the commit, and my attempts at getting
a clean WC afterwards:
("Accès refusé" means "Access denied")
("Le fichier existe" means "File already exists")

Checked out revision 1009.
You will note that the commit said "Commit succeeded, but ..." I really
believed Subversion, until I updated and saw that the files were not
there.
After the commit, in r1009, the resolved/0003 folder exists, but does not
contain the expected files. It should have contained a status.txt, which
does exist in r1008.
At this point, I loaded a hot-backup at r1004, and dumped/loaded
r1005:1008.
So, my working repository will be at r1008. I have a copy of the bad
repository, if anyone is interested. It is ~260 Mb, uncompressed.
Unfortunately, before I send that to anyone, I'll need a verbal NDA. My
customer requires an NDA.
Anyway, the repository is also available at
https://svn.hopto.org:8193/borked/rac/leadmanagement/
Again, I'll need a verbal NDA before I disclose a username/password for
you to
access the repository.
Environment:
C:\>svn --version
svn, version 0.30.0 (r7178)
compiled Sep 24 2003, 20:10:05
Apache 2.0.47, Win 2K SP4.
