Multiple copies of messages?
by William Bradford 01 Aug '98

01 Aug '98

I'm running 1.0b5 with apache 1.3 and python 1.5.1 on a DEC UNIX 4.0D machine (AlphaStation 200 166mhz), and some of my list members are getting multiple copies of the same message.. Also, I found that you cant "en masse" add more than 25 or so people at a time, or the operation bombs out with an "operation would block" message on the error bug page returned by the web browser... bill -- Bill Bradford * mrbill(a)frenzy.com ------------------------------------------- "One World, One Web, One Program" - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Fuhrer" - Adolf Hitler

Reposting Form Data
by Barry A. Warsaw 01 Aug '98

01 Aug '98

Maybe someone out there with more HTTP experience than me can answer this question. If I have a CGI script that issues a redirect using the `Location:' header, I can get the Web browser to go to the relocated page with no problem. It even still shows the original URL in browser. Cool so far. However, if what I'm doing is posting some form data, the browser gets redirected, but the form data doesn't get reposted to the new URL. Verified under NS4/Unix and IE3. This is a real pain for something I'm trying to add to Mailman. I'm sure there's some haughty security justification for the non-reposting of form data, so the natural question is: can I get around this? :-) Thanks, -Barry

problem with "Edit Options"

Potential gotcha
by Barry A. Warsaw 31 Jul '98

31 Jul '98

Corbett has been very kind in allowing me access to his machine to debug his problems. Since others have reported similar problems, I want to give you a heads up. Please double check that the programs in /home/mailman/cgi-bin are group owned by `mailman' and have the group sticky bit set. This is imperative; Mailman just won't work without this. I know need to figure out why the install procedure is broken on some systems, and how the driver script can better report and recover from these problems. Thanks Corbett! -Barry

I had the same problem (some people received even about 10 copies of the subscription message), and yes, some members received also messages twice. The latter problem disappeared after I set number of outgoing connections to 1 instead of default 5 in Mailman. However mass subscriptions are still sent more than once to some users. Milan Zamazal

gid error
by m* 30 Jul '98

30 Jul '98

i keep getting this error. i thought i had followed the dirs but i must be missing something: Jul 30 11:58:47 orifice Mailman mail-wrapper: Failure to exec script. WANTED gid 8, GOT gid 1. (Reconfigure to take 1? i let the configure script determine the gid and it got mail's gid 8 but it appears that the script is trying to run as daemon's gid. i configured mailman once before ( i believe it was an earlier version ) but did not have this problem. thanks so much, mark

>>>>> "L" == Luke <luke(a)indy.net> writes: L> none of these failed Sorry Luke, I've been out sick since just about after our last email exchange. Are you still having problems? If you're getting that low-level bug report then there *must* either be problems importing sys, or something that's causing the functions in the except clause of run_main() to fail. I still suspect that logger or multi are not getting instantiated correctly. Please try this version of the driver script and see if that gives you any more clues as to what's up. This will print error information to whatever stderr is for your CGI scripts.
