I've just spent two days manipulating a bunch of mbox files into archives.
Let me tell you how it goes:
1. Blow away the html archives. You may prefer to use that arch command
we were just discussing, but I used "rm -rf
2. Stop mailman's qrunners using "/etc/init.d/mailman stop"
3. Run bin/arch on the huge mbox file.
4. Discover that bin/arch is consuming all the memory and swap on the
system, and your system has ground to a halt.
5. Kill bin/arch. Wait for the system to recover the swap space. At this
point, I should have rebooted because I think this is when my list
config.pck file got corrupted. Restore the config.pck file from backup.
6. Discover an awk script in the mailman archives that will split the mbox
archive into managable chunks. Fix it so that it splits them into 500
message chunks instead of the 80 message chunks it defaults to.
7. Run bin/arch on all the chunks one at a time.
8. Discover that the mbox file had a bunch of un-escaped "From " lines
that confused bin/arch and so you have a bunch of half-articles in today's
archive page that shouldn't be there. Run bin/cleanarch to fix them, blow
away the html archives, and then resplit the mbox file and run bin/arch on
9. Discover that in early 2000 some members of your mailing list were
using a MUA that set year to "100" in the "Date: " header, which confused
bin/arch. Fix those up with sed, then blow away the html archives, then
resplit the mbox and run bin/arch on the splits.
10. Discover a couple of "From " lines that bin/cleanarch didn't fix
because somebody was quoting the mail headers of another message. Fix
them with sed, then blow away the html archives, then resplit the mbox and
run bin/arch on the splits.
11. Discover you missed a "From " line in one message, say "to hell with
it", restart mailman, and go to bed.
