[darcs-devel] [issue1273] renameFile: does not exist (No such file or directory)

[Zooko]

New submission from Zooko <zooko at zooko.com>:

darcs get failed on one of the tahoe-lafs buildslaves:

http://allmydata.org/buildbot/builders/hardy2.6/builds/145/steps/darcs/logs/stdio

It appears to be a sporadic failure.  The error message is:

darcs:
/home/buildslave/.darcs/cache/pristine.hashed/0000029303-d270307a184c266d2548acb104c502b9767e79b5a3eed1aa2acf32a72813da0e-new:
renameFile: does not exist (No such file or directory)

and then "darcs get" emitted no output for 1200 seconds so it was killed for
taking too long.

The error message makes me wonder if there are some problems with the ordering
or locking of access to files in the shared cache.  Perhaps that file (which
ends with "-new") was created in one step and then relinked in a second step,
and perhaps the file was gone by the time darcs tried to execute the second
step, possibly because another instance of darcs had removed it while using the
cache?
