Size is nice because it's much cheaper to check. I don't know if mass
uninstalls will be so common that this is actually something we have
to worry about, though.

Indeed - the tempfile module is very helpful in that regard.

Cheers,

[Python-Dev] doc error in 2.6.2

2009-05-15 Thread Leo Jay 
There is a syntax error in the client side code of
"SocketServer.UDPServer Example" in
http://docs.python.org/library/socketserver.html:
import socket
import sys

HOST, PORT = "localhost"
data = " ".join(sys.argv[1:])

Obviously, it should be:
HOST, PORT = "localhost",

Please follow the directions in http://docs.python.org/bugs.html
to report this on bugs.python.org -- that ensures that it won't get
lost.

Remove one byte from the file and your hash is already different.


Which also means that in that case you can skip computing the 
MD5.  The size allows you to easily notice an overwrite/corruption 
without further processing.

I think the path is the info that should be looked at.


By "a file that belongs to more than one project" I meant a single 
file on *disk* (i.e., one absolute path).



But I don't think you want to leave alone a file with identical 
size/checksum that belongs to more than one project when it's not 
the same absolute path.


That wouldn't be "a file" then, would it?  ;-)



Here's an example why : if two different packages includes the
"feedparser.py" module
(from the FeedParser project) for conveniency, and if you remove one package,
you *do* want to remove its "feeparser.py" module even if it exists 
in the other

project.


Right, that would be *two files*, though, not one file.

In most cases the files will actually match, so the sizes and dates will be
the same and the checksum must be computed to verify the match.

RPM does this when asked to Verify a package.  It is faster than Removing a
package, and Verifying all installed packages takes a reasonable amount of
time.  I don't think Python would be any worse at verifying its own
packages, and it would normally have less data to verify, so it should be
fast enough.
