bzr: ERROR: [Errno 5] Can't open 'C:\tmp\tempfile.tmp': Zugriff verweigert ("Permission denied")

[Daniel Hahler]

Branching a subversion repository fails with some strange "Permission denied" ("Zugriff verweigert") error:

C:\foo\bar>bzr branch https://svn.typo3.org/TYPO3v4/Core/branches/TYPO3_4-1
bzr: ERROR: [Errno 5] Can't open 'C:\tmp\tempfile.tmp': Zugriff verweigert

The directory is writable though (i.e. "touch C:\tmp\tempfile.tmp" works).

I'm using bzr 1.13 (includes svn plugin 0.5.3) on Windows XP (with cygwin installed).

From .bzr.log:

THis suggests you might not have permission to open all the files in the repository, could that be correct?

[Daniel Hahler (blueyed)]

I'm not sure what you mean: the repository is read-only for me, yes.
But branching it worked fine from my server (which runs Ubuntu Hardy). I then copied the repository/.bzr directory to my Windows machine and can now update/pull from there without further problems.

[Jelmer Vernooij (jelmer)]

subvertpy seems to generate the same path for temporary files continuously

[Jelmer Vernooij (jelmer)]

This is a bug in svn_io_open_unique_file.

[Chris E (cbz)]

Is there an indication what the bug is ? It seems that this problem is more likely to occur over larger imports - i presume because the function itself is called more often.

[Jelmer Vernooij (jelmer)]

This actually appears to be triggered by some virus scanners, it's not a bug in Subversion.
