Hello,
I've posted this issue description in the users list and Karl Fogel
advised me to post it here as well.
The problem I encountered is as follows: during every commit, I change a
property of all files in a repos in the pre-commit script within the
current transaction. This works quite well, except for the case when a
top-most directory is copied to root of the repos. In this case the
property is only updated for the files in the new directory and stays
the same for all other files.
I can only reproduce this issue with the FSFS back-end.
The sequence of reproducing this issue:
1. Create a FSFS-based repos, set up the attached script as a pre-commit
script:
$ svnadmin create --fs-type=fsfs tmprepos
$ cp test.py tmprepos/hooks/pre-commit
$ chmod +x tmprepos/hooks/pre-commit
2. Checkout the repos, create a directory and put a file there:
$ svn co file:///tmp/tmprepos/ wc
$ svn mkdir wc/dir1
$ echo test > wc/dir1/file1
$ svn add wc/dir1/file1
$ svn ci -m "" wc
3. Find out the file's 'count' property:
$ svn propget count file:///tmp/tmprepos/dir1/file1
1
4. Copy the directory and check the 'count' property of old and new
files (check out that ):
$ svn cp file:///tmp/tmprepos/dir1 file:///tmp/tmprepos/dir2 -m ""
$ svn propget count file:///tmp/tmprepos/dir1/file1
1
$ svn propget count file:///tmp/tmprepos/dir2/file1
2
I tried different scenarios (changing files, file's properties, copying
directories inside other directories, and so on) and it looks like that
only copying the top-most directory to root reveals this effect. Also,
the property of files in other directories don't get updated too.
I'm also attaching a shell script with all the commands to reproduce the
issue.
Regards,
Dmitry
