Refactor out the crazy main loop and threading goop into a function that runs the main loop on an arbitrary number of server instances

Commit by micah :: r7459 spreadfs/pinefs/rpc.py:

Use select() when receiving UDP packets so we can include a timeout that avoids hangs on exit

Commit by micah :: r7186 spreadfs/spreadfs.py:

Timestamps work better if I call ctime() rather than formatting the function itself in a string

Commit by micah :: r7165 spreadfs/spreadfs.py:

Oops, rsplit() is a 2.4-only feature. We can get by with regular split() for now...

Commit by micah :: r7129 spreadfs/spreadfs.py:

• Added timestamps to the log
• Completely ignore exist/endExist events. We do a lot of event transformation now, so we might as well bail out quick for the ones we don't end up using
• Log transformed events rather than raw events
• As part of the event transformation, ensure that filenames are relative not absolute. This fixes at least some of our weirdness with moving files around.

Refrain from trying to update stat() info on a directory that no longer exists

Commit by micah :: r6972 spreadfs/spreadfs.py:

• Prevent a potential problems with moving files between disksets by converting 'deleted' FAM events into 'changed' events when the underlying file or directory still exists on at least one disk
• Set all directory timestamps to the current time on any change rather than using the newest timestamp we find in the diskset. This avoids client-side caching problems with some types of directory modifications.

Commit by micah :: r6921 spreadfs/spreadfs.py:

Detect duplicate files on the DiskSet and log any problems we find

Commit by micah :: r6903 spreadfs/spreadfs.py:

Yay, fixed caching. Created/delted files on any of the underlying mounts now show up immediately on the NFS clients.

Commit by micah :: r6902 spreadfs/spreadfs.py:

We should really be using unbuffered file objects. This might gain us a little speed

Commit by micah :: r6901 spreadfs/ (pinefs/srv.py spreadfs.py):

Working toward getting the cache behaviour correct. This should implement mtimes and such for directories, as well as a handful of other attributes

Commit by micah :: r6899 spreadfs/spreadfs.py:

Correctly update the directory cache and invalidate file objects as appropriate based on FAM events

Commit by micah :: r6898 spreadfs/spreadfs.py:

Look, lots of experimental FAM stuff that doesn't seem to break!

Commit by micah :: r6897 spreadfs/fam/test.py:

No hardcoded python2.2!

Commit by micah :: r6896 spreadfs/ (8 files in 3 dirs):

Import a copy of python-fam 1.0.2, with a new __init__.py and a less-crummy Makefile that doesn't hardcode python 2.2

Commit by micah :: r6893 spreadfs/spreadfs.py:

Fix statvfs() and create() docstrings

Commit by micah :: r6887 spreadfs/spreadfs.py:

Remove debuggative cruft. Yay, this seems to be somewhat fast now.

Commit by micah :: r6886 spreadfs/spreadfs.py:

Replace berkeley db entirely with a filesystem-based database

Commit by micah :: r6885 spreadfs/spreadfs.py:

Speed up the mapper database muchly by switching from shelve to anydbm and removing the sync()

Commit by micah :: r6884 spreadfs/ (. spreadfs.py):

Refactor the file mapping code, use a persistent database mapping file IDs and handles to paths. Now the spreadfs server can be restarted without any stale handles showing up
