    Hi,

    Traceback (most recent call last):
    File "/usr/bin/mini-dinstall", line 1222, in run
    self._index_all(1)
    File "/usr/bin/mini-dinstall", line 1216, in _index_all
    self._index(self._arches + ['source'], force)
    File "/usr/bin/mini-dinstall", line 1303, in _index
    self._index_impl(arches, force=force)
    File "/usr/bin/mini-dinstall", line 1333, in _index_impl
    self._make_packagesfile(self._relpath(arch))
    File "/usr/bin/mini-dinstall", line 1064, in _make_packagesfile
    self._make_indexfile(dir, 'packages', 'Packages')
    File "/usr/bin/mini-dinstall", line 1044, in _make_indexfile
    os.dup2(outfd, 1)
    OSError: [Errno 16] Device or resource busy

    According to the Linux kernel mailing list, EBUSY is a legitimate error
    for dup2 (race condition). See also the dup2(2) manpage.

    Fix: retry a few times.

    Hi.

    Thank you for your interest in mini-dinstall and your bug report.
    My apologies for not being able to reply earlier. I had an email outage.

    Do you want this fixed for sarge? I'm not sure how often the error occurs.

    How often, with what delay?

    Kind regards

    Thomas

    Hi,

    Thomas Viehmann:
    Severity: important

    Do you want this fixed for sarge? I'm not sure how often the error occurs.

    Depends on how loaded the machine is. I've seen it twice in the last week.

    Fix: retry a few times.
    How often, with what delay?

    I don't know -- until whenever the other process has swapped in and/or
    gotten a slice of CPU time, and released the lock... my off-the-wall
    guess is that once immediately and once after a few seconds should be sufficient.

    Hi.

    I've put up mini-dinstall 0.6.19 at [1].
    This intends to fix precisely this bug. (Find details in lib/misc.py.)

    If you don't find any problems with it, I'll be looking for a sponsor in
    the afternoon (CEST).

    Kind regards

    Thomas

    Actually, I couldn't help but change the default for the recognized
    release also.

    Kind regards
