So now I have installed a brand new MySQL-python-2.9.2a2 explicitly compiled against reentrant mysql libraries (libmysqlclient_r, in Debian's libmysqlclient10-dev package). I also installed ZMySQLDA-2.0.9b1 which compounds MySQL-python reentrancy by serializing all mysql requests with a lock. We've also completely reformed the site so as to get rid of that huge number of pythonscripts (they were mostly duplicates and we manage to remove the redundancy using ZClasses). Segfaults are still with me, however, unless I disable the cycle-gc, of course. Tomorrow I'll try and get a core to see what gdb can tell me. Anything you guys suggest I take a look at? (besides the C stack trace which will probably be pointing somewhere inside the GC) I'll also try go get the remaining non recompiled python scripts fixed, so as to please Anthony Baxter :-) But for that I'll need one of these: * a way to make the 'needs recompiling' log message give me the path to the object. Since that message happens at __setstate__, getPhysicalPath() doesn't return anything useful (no acquisition wrappers). * a way to know whether a Python script needs recompiling or not. So that I can ZCatalog only the non recompiled python scripts. I tried asking the ZCatalog for all the python scripts and later recompiling them, but I managed to miss a lot of them somehow. It's as if the ZCatalog decided that it wasn't going to really catalog ALL python scripts. -- Ideas don't stay in some minds very long because they don't like solitary confinement.
