Forum OpenACS Development: AOLServer 4.0 Support in 5.0?
I don't rememebr seeing the outcome of il8n and charset decisions for aol4. The last I heard, the charset implementation was different from the aD patches, but our implementation was being considered.
A google search of openacs.org shows a bunch of fixed bugs for aolserver 4, but I can't find any references to the il8n issues.
Can anyone shed light on how well aol4 is supported vs. the aD patched aol3.3, and perhaps we should TIP moving to aol4 as the oficially supported server for 5.0 since it would be a good time to make such a major change.
I believe internally AOL has cut over to 4.0 (digitalcity.com definitely has, not sure about other sites) so I am pretty confident it has gotten a good workout and is production ready.
Yes, I think we should switch to 4.0 as the recommended version although I am not sure we can get the install docs revised in time for 5.0 so it might happen with 5.1.
Scott is in the process of a major refactoring and is hoping to release another version in the next few days. If you aren't on the AOLserver mailing list, here's some information on the direction nsopenssl is heading in:
Restart problems, multiple people reporting having to send a kill signal twice with a pause in between and/or kill -9. Sounds like a problematic and annoying bug but not a show-stopper for most people.
One or two people also seem to be reporting AOLserver 4 respawning infinite times until the box comes to a halt. It is somewhat unclear, but it appears that this is likely due to attempts to remotely exploit an as yet unpatched security bug AOLserver 4.0, and those (presumably unsuccessful) attempts had the effect of a DOS attack. Supposedly this hole is very difficult to exploit successfully, an it is thought that the bug does not exist in AOLserver 3.3+ad13, but AFAIK no one has double checked and verified that.
On a more pleasant note, Zoran recently announced some promising alternative Tcl interp initialization work giving reportedly 1/3 the memory footprint and 50 times faster thread startup than baseline in AOLserver 4.0.
