python25 persistent checksum mismatch

[perfgeek@…]

For about a week now I've been trying to install gimp on a 10.5.1 Intel-based iMac. After the dbus-glib problem was resolved, the next one was checksum mismatch on python25. This has persisted after several sync's, cleans and installs over a number of days. Either there is something amiss with the port, or this submittor needs a gentle tap with a clue bat.

I just downloaded the file anew and compared the checksums and they all match. The file size of your Python-2.5.1.tar.bz2 file matches the one here, so this is not an obvious bug.

This could mean that either your network is playing tricks on you or your checksum calculation is going awfully wrong. Please post the result of

sudo port -d checksum python25

Sorry about that - had no idea that one couldn't just cut and paste. Will try to remember that for the future.

[mww@…]

I'm sorry -- the checksums in the Portfile match the official ones on ​python.org (the md5 for Python-2.5.1.tar.bz2). I also downloaded the file again here and checked: The checksum matches.
Sorry, but this has to be some kind of networking error on your side (perhaps a proxy?) -- please do a

port clean --all python25

and try again.

[perfgeek@…]

Hopefully this will format correctly...

I take it then that the checksums I reported are indeed incorrect. Where would I find the Portfile to make sure that my Portfile has the correct checksums?

As for proxies, I've no clue - my ISP may indeed be running a transparant one on me, but I don't have any (known) of my own. Mac, router, dlsmodem... big bad internet...

I tried downloading the tar.bz2 by hand, and it wouldn't even unzip:

[rick:~] perfgeek% bunzip2 Python-2.5.1.tar.bz2 

bunzip2: Data integrity error when decompressing.
	Input file = Python-2.5.1.tar.bz2, output file = Python-2.5.1.tar

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

bunzip2: Deleting output file Python-2.5.1.tar, if it exists.

So, on a hunch/whim, I tried grabbing the file to netperf.org, and then pulling it down to my system via ssh, and that file would untar. I've not gone so far as to try replacing the one port downloaded with it yet.

[rick:~] perfgeek% cmp Python-2.5.1.tar.bz2 Python-2.5.1.tar.bz2.httped 
Python-2.5.1.tar.bz2 Python-2.5.1.tar.bz2.httped differ: char 1146753, line 4963

So, the hypothesis of a proxy problem is plausible, or shudder - a data pattern induced error somewhere along the way. It cannot be a "plain" proxy problem though, because when I arranged to pull the file via http from netperf.org, that one compared just fine with the one I ssh'd from netperf.org.

[mww@…]

just copy the file you got manually to

/opt/local/var/macports/distfiles/python25/Python-2.5.1.tar.bz2

and retry. I suppose this will make the checksum error go away for you -- finally.

[perfgeek@…]

It seems to have done that, and now the rest of the myriad of dependencies for gimp are installing.

[perfgeek@…]

So, installation is complete. Are longish sequences of gimp_wire_read errors already a known issue? Something to do with not finding a symbol called _PyGimpChannel_type.
