RE: [Zope] ZServer Must Be Continually Re-Started

I also have a similar problem (RH v7, Zope v2.3.0); ps aux shows normal python processes, top shows no unusual CPU usage, Z2.log shows the last GET request and that's it, there simply is no response from zope until I restart it. I just enabled verbose logging with the -M switch on z2.py today, to try to get more information. My setup includes ZEO v0.4, does anyone else having this problem use ZEO?

RE: [Zope] problem selecting integers from mysql
by sean.upton＠uniontrib.com 11 May '01

It would have to be out of the range of a 4-byte integer, which is not likely in most applications. MySQLDA sees MySQL INT and INTEGER (4 byte) type fields as longint types, which are also 4 byte integers (which is -2,147,483,248 to 2,147,483,248). I am not sure about MySQL's BIGINT type, which is an 8-byte integer, which is so rediculously big (2^64 or 18,446,744,073,709,551,616 possible numbers), it's hard to imagine anyone using. I'm not sure how Python's __int__() handles an 8-byte value, I cannot seem to find an answer in the Python Reference Manual...

[Tracker]Tracker errors and fixes on HP/UX 11.00 with Pyth on 2.0
by Farrell, Troy 11 May '01

I sent this to the tracker-dev(a)zope.org list, but due to the lack of activity on that list, I think it might be better placed here. When looking at the diffs below, note that I always append a # to a line of code that I edit in someone elses sources. Troy -----Original Message----- From: Farrell, Troy Sent: Friday, May 11, 2001 11:06 AM To: 'tracker-dev(a)zope.org' Subject: Tracker errors and fixes on HP/UX 11.00 with Python 2.0 Hi Guys- I've installed Tracker before on Linux/i386 with Python 1.52 before without problems, but when I try it with HPUX 11.00/Python 2.0 and Zope 2.3.1 or 2.3.2, there are many issues. I seem to have fixed most of them and I felt that you guys could use the fixes, so here we go: 1) Inside the Tracker ZClass, I've changed /Control_Panel/Products/Tracker/Tracker/propertysheets/methods/TrackerItem/p ropertysheets/methods/index_html to include the following lines after the comment at the beginning: <dtml-unless expr="PATH_TRANSLATED == URL0[_.len(BASE0):]"> <dtml-call expr="RESPONSE.redirect(URL0)"> </dtml-unless> These lines fix the problems associated with the TrackerItem ZClass being inside the Tracker ZClass instead of the TrackerIssue ZClass. These problems show themselves inside the manage_tabs method for a TrackerItem's index_html 2) Change all the appends with too many arguments to appending tuples, and change tracker_role() so that it doesn't throw up an error when it tries to convert a tuple to a string, because we can't convert a tuple to a string. Please review the changes to tracker_role() in TrackerMisc.py especially well. I'm not very confident about them.

Threads in ExternalMethods
by Juan Carlos Coruña 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.

But when I test the query I get the number plus an "L" appended to the end. For example I get 1L, 32L, 6533L. I assume the L means longint but does anyone know how to get rid of it? thanks much -Kevin __________________________________________________ Do You Yahoo!? Yahoo!

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> ...

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?
