Threads in ExternalMethods
by Juan Carlos Coruña 11 May '01

11 May '01

Hi all, I am now trying to create an ExternalMethod that executes a long process (about 30 seconds) in a new thread and then this thread sends the result per e-mail. The ExternalMethod must return inmediatly. I need this behavior in order to not block the user while browsing. Are there anybody that can help me?

put int() around your results; it will convert a longint to an integer.

RE: [Zope] DTML - change document title?

The problem with this: A large number of pageviews will fill ZODB up with copies of the document. It might be better not to use <dtml-var standard_html_header>, but instead write the header into the document and do this: <html> <head> <title><dtml-in sqlSelectTitle><dtml-var sqlTitle></dtml-in></title> </head> <body> ... Modify to suite your needs.

Re: [Zope] ZServer Must Be Continually Re-Started: my Method to stop zope dead:
by Gilles Lavaux 11 May '01

11 May '01

Hello This thread is going around since several years now (and zope version). I am aware of this problem because I encounter it since zope 0.9.xxx (or was it 1.0.xx??) :-); and I would love to have a solution... I only use zope basic functionality: Zserver + one postgreSQL adapter (Zpopyda at this time) and use some external methods , also some mailhost object. No Zclass or fancy products. I am personally thinking that ONE of the problem is that there is no time-out on the Zserver socket, I think that if for some reason a request get stuck, the thread is never released. If you use all the thread pool, your server doesn't reply anymore. Exercise (It's just a silly test I have done 5 mins ago): - my Zserver is configured to have a pool of 4 threads - I create en external method which loop - I create an DTML (hang_test) method which call this external method, then I make 4 copy ( hang_test1,hang_test2, etc..) - from a browser I call 2 of them: the requests get stuck as expected: I use the debug page to check them: (I have 2 long running threads at this time) 1)Opened:Fri May 11 09:12:13 2001 (488.23s) HTTP_ACCEPT_ENCODING : 'deflate, gzip, x-gzip, identity,*;q=0'. SERVER_PORT : '8080'. etc..... 2)Opened:Fri May 11 09:19:54 2001 (27.81s)..... 3)debug request. 4)free. - I block the zserver by calling the other hang_test3, hang_test4 methods. - that it. My Zope server is now bloqued since 15 minutes, I will see if it reply again later on. - eventualy (if I have some time) I will redo the same test using Zserver with a timeout socket library to see if it act the same... please understand that this is just a demonstration, I know that doing infinite loop is silly. In real life, one blocking condition I saw(I am almost sure of that, just almost) was the mailhost object: In case of empty(or bad, I don't remember) mail recipient, the request was blocking when it was doing the sendmail. This server was dying every few days. - my zope server is still dead: I have requests in my browser dated from 33 mins. have someone a solution?

log files

is this the only way to use stupid_log_files? " $ python1.5.2 z2.py ZSYSLOG_SERVER="syslog.mydomain.com:514" \ STUPID_FILE_LOGGER=var/Zope.log" " i got this from: http://www.zope.org/Documentation/Misc/LOGGING.txt or can i put this in a config file? i looked inside z2.py and found no place to put it. what am i supposed to expect here? i tried the command line approach but i was looking for the file and i don't think it create the file. or is it gonna be create when the first error comes?

by Kevin L 11 May '01

11 May '01

I know this is probably really easy but I can't find it anywhere in the docs. I have a dtml document that needs to have a different title every time (based on a database call). How can I set the title attribute from dtml? thanks much -Kevin __________________________________________________ Do You Yahoo!? Yahoo!

Disappearing images in python product...
by sean.upton＠uniontrib.com 11 May '01

11 May '01

I have a class in a python product that defines the following: manage_admain = Globals.HTMLFile('dtml/editForm', globals()) editad_image = Globals.ImageFile('images/editad.png', globals()) Within dtml/editForm.dtml: <dtml-var editad_image> I used this to display an image within a managment interface page I had set up. The image won't load (it is missing). This used to work, but at some point recently became broken. I'm not sure why; I can't pinpoint exactly when it happened. At some point, I changed the meta-type of this class, but I think that is all I have really done... Thoughts?

Zserver shutting down - Broken Pipe
by Laurie Nason 11 May '01

11 May '01

Just over the last couple of days I have been having the same problem with one of our Zope development servers. It starts up fine, then after a while (undetermined as of the moment)the ZServer will just hang (error messages etc. below). I have created/am still creating my own ZClass on this server if that has anything to do with it. I haven't installed any external products (yet). Here are the stats on the server: Athlon 1200 512MB Linux Mandrake 7.2 Zope Version : Zope 2.3.2 (binary release, python 1.5.2, linux2-x86) Python Version: 1.5.2 (#10, Dec 6 1999, 12:16:27) [GCC 2.7.2.3] System Platform: linux2 Here is the STUPID_LOG_FILE output that occurred before the crash: 2001-05-11T16:12:59 ERROR(200) ZServer uncaptured python exception, closing channel <select-trigger (pipe) at 81a8178> (exceptions.OSError:[Errno 11] Resource temporarily unavailable [/var/zope/Zope-2.3.2-linux2-x86/ZServer/medusa/asyncore.py|poll|83] [/var/zope/Zope-2.3.2-linux2-x86/ZServer/medusa/asyncore.py|handle_read_even t|335] [/var/zope/Zope-2.3.2-linux2-x86/ZServer/medusa/select_trigger.py|handle_rea d|77] [/var/zope/Zope-2.3.2-linux2-x86/ZServer/medusa/asyncore.py|recv|287] [/var/zope/Zope-2.3.2-linux2-x86/ZServer/medusa/asyncore.py|recv|475]) The output in the shell that started zope reads (this is repeated a few times before the final crash): Unhandled exception in thread: Traceback (innermost last): File "/var/zope/Zope-2.3.2-linux2-x86/ZServer/PubCore/ZServerPublisher.py", line 97, in __init__ response._finish() File "/var/zope/Zope-2.3.2-linux2-x86/ZServer/HTTPResponse.py", line 281, in _finish stdout.close() File "/var/zope/Zope-2.3.2-linux2-x86/ZServer/HTTPResponse.py", line 338, in close Wakeup() File "/var/zope/Zope-2.3.2-linux2-x86/ZServer/medusa/select_trigger.py", line 74, in pull_trigger os.write (self.trigger, 'x') OSError: [Errno 32] Broken pipe Anybody come across this before???
