[Zope-dev] zserver medusa timeout? anyone?
Hi, I would like to know if ANYONE has ever put timeout parameter of ZServer/Medusa to work, i.e, if changing this timeout value to a low value and actually seen it to work, i.e, closing zombie channels. Anyone done this? I've tryed almost everything on my limited knowledge of zope/python, creating zombie requests running in a zserver with a timeout=realylowvalue but the request was never closed. Maybe I'm realy missing something here.

[Zope-dev] kill Zserver zombie channels
Hi, blatantly taken from ZServer/HTTPServer.py and adultered is this code to kill zhttp channels used in zope by way of an external method: def killzombies(): import ZServer from ZServer import HTTPServer from ZServer import medusa from ZServer.medusa import asyncore from ZServer.medusa import http_server for channel in asyncore.socket_map.values(): if channel.__class__ == HTTPServer.zhttp_channel: channel.close() return 1 I ignore here the zombie_timeout, Im just killing all channels. The problem is that I also kill the main python process. I would apreciate if any zserver/medusa guru can iluminate my mind on what I'm doing wrong here. In this code I only close zhttp_channels and not zhttp_server ones, so I dont understand why the server is also closed.

[Zope-dev] zope script execution timeout
Hi, first a more python/httplib.py specific question: I know there has been a patch for this module to support socket timeout exception but I cant find the bastard. Anyone? I can see that in Python2.0 the urllib module now has a timeout implementation but is it safe to replace urllib.py from 2.0 in zope's python modules? I know... I will try it... but if someone has any experience in this would help. Now more zope/Zserver specific: ZServer/medusa has a timeout option, I reduced this value but that just doesnt seems to work, I still have zombie channels running for days. Meanwhile I'm working on a External Method that imports Zhttpserver stuff where I can enter in the zope's channels poll and find the zombie ones and hopefully killing/closing the bastards, thats just what Zserver.maintenance() should do but doesnt. A final point is I know in unix I could use the signal module but I'm working on NT (dont laugh like a drain please :-), which doesnt support signals but supports a "structured exception handling" (whatever this means...), bottom line, is there a signal like module in python working on NT that I could use to for instance wrap httplib and urllib calls?

[Zope-dev] Fwd: [Zope-ZEO] zope+zodbc+zeo issues
>From: "Júlio Dinis Silva" <[EMAIL PROTECTED]> >To: [EMAIL PROTECTED] >Subject: [Zope-ZEO] zope+zodbc+zeo issues >Date: Wed, 31 Jan 2001 18:46:16 - > _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com. Hi, We are running for some months a zeo-based site where clients have a zodbc connection to mssqlserver. We had defined a big value for the clients cache, but recently we drastically decrease that value due to memory problems. The problem we are debugging now is that once in a while one of the clients became zombie and going to a good client and doing the "close zodbc connection" the zombie one start moving ok. So what is happening here? We think since we decrease the size of our clients cache, activity in sqlserver is now bigger, so clients request more often sql executions. We believe there is something wrong having this zodbc object shared by zeo clients where each one of the clients have a NT ODBC DSN source to the sqlserver. So question is: is it safe to share the same odbc adapter connection with zeo clients or one should take some special care. We are moving into trying to put each client using each own zodbc connection. Dont ask me how cause we are going to hit it with a large hammer. Any comments? thanx, Julio Dinis Silva ps. sorry if this message goes in html format cause this fuc. hotmail webmail client now has a activex object that I cant disable.
