ParsedXML
by Chris Herrnberger 18 Jun '02

Greetings: Started testing ParsedXML and the following error is forwarded up starting the zope server: 2002-06-16T01:49:38 PROBLEM(100) Init Ambiguous name for method of Products.ParsedXML.ManageableDOM.DOMManageable: "manage_main" != "manage_DOMTree" The following steps were taken on this SuSE 8.0 system: Installed python 2.1.3 from source Installed PyXML-0.7.1 Build parsedXML via instructions provided in the package. Everythin compiled fine and parsedXML is available from the dropdown as well as in the products section. Everything seems to be correct. Yet the error message.? Perhaps I missed something..? Many thanks in advance. Chris H.

I just set up the same situation and it worked for me... (ie I get YES back) My guess is that you aren't returning a list. My get_list() looked like: return ['test','test_str','yes'] -----Original Message----- From: Aseem Mohanty [mailto:aseem@neurobehavioralsystems.com] Sent: Tuesday, 18 June 2002 2:19 a.m. To: zope(a)zope.org Subject: [Zope] another DTML ques I have a PyScript that returns a list of strings Somehow I am unable to do the following: <dtml-let ll="get_list()"> <dtml-if "'test_str' in ll"> YES <dtml-else> NO </dtml-if> </dtml-let> I know that 'test_str' is in the list.

Zope and SOCKS
by Jon Jarboe 18 Jun '02

18 Jun '02

Is there anything special about the Zope environment, which would prevent it from being able to use SOCKS5 in a normal configuration (i.e. using the standard python interpreter and libraries bundled with Zope) on Solaris 8 (Sparc)? I have set up SOCKS5, and am able to get through our socks proxy with a simple "runsocks python" environment. So I know that my SOCKS client config is good, that python is able to go through the SOCKS libs, and that the SOCKS server is working correctly. As a sanity check, I verified that it fails without the "runsocks". When I try changing the "start" script to use "runsocks python z2.py ...", and then use an External Method to talk to a server on the other side of the proxy, it seems to ignore the SOCKS libs and timeout. I have verified that LD_LIBRARY_PATH and LD_PRELOAD are visible in my External Method, that my External Method gets called, and that the SOCKS server is not receiving traffic from my host when the External Method is called. It seems as if the Zope libs are forcing my method to use the builtin libsocket.so.1 instead of the desired libsocks5_sh.so. I could try building a SOCKS-aware version of python's _socket.so module, but it seems like that shouldn't be necessary given that I can successfully use SOCKS from python outside of Zope. Any suggestions? Thanks, Jon __________________________________________________ Do You Yahoo!? Yahoo! - Official partner of 2002 FIFA World Cup http://fifaworldcup.yahoo.com

Re: [Zope] win32 mysql database adapter

CORRECTION > > http://sourceforge.net/project/showfiles.php?group_id=22307 > > ZMySQLDA was not a problem but it depends on a separate > package, MySQL-python, for which there is no binary. The > executables of that name at the link above are simply > self-extracting zips of python scripts. This last statement was incorrect. MYSQL-PYTHON-0.9.1.WIN32-PY2.2.EXE, found at the above site, can be opened with Winzip but also WORKS AS AN INSTALLER (if, and only if, python 2.2 is already installed). Having done considerable groping on this one, I would not wish to add further confusion for anyone else.

2 zope faster 1 zope running
by Андрей Пучин 17 Jun '02

17 Jun '02

Hello! I have tested ZOPE under heavy load (about 100-200 users simultaneously) and noticed that 2 zope running on 1 PC works (processing requests) faster than 1. Zope runs under Windows XP with -t 10 options. Test were made with RationalRobot. What's wrong with my ZOPE installation?? Is there any performance tune tricks?? Thanks Andrew

Re: AW: [Zope] 2 zope faster 1 zope running
by Matthew T. Kromer 17 Jun '02

Copying Zope @ Zope.org since this is useful information. My numbers below are approximations, not hard figures. Its derived from experimental observation. A python bytecode, on average, executes about 50 machine instructions. You probably want to let a whole CPU quanta expire before voluntarily switching threads. Generally a CPU quanta will be about 5 milliseconds. A 1GHz pentium will execute about 1,000,000 instructions / millisecond, or about 100,000 python bytecodes / quanta. The typical Zope publishing path is about 1,000,000 bytecodes or more -- so letting that path be interrupted 10 times or more is overkill (for Zope). Using my numbers you could argue for a much higher ratio. (Ie, if you believe me, Zope "wants" a sys.setcheckinterval(100000) on a 1Ghz machine. From experimental observation I have detected a levelling off in benefit at about pystones/50. This becomes very noticable on a multiprocessor machine. I believe the levelling off effect comes from other normal 'blocking' operations inside Zope which cause one thread to suspend. Hence the factor of 500 discrepancy :) The rationale is due to overhead in thread switching, and "thruput" optimization. Consider the following example: Two threads wish to count from 1 to 10. After each thread counts a single digit, they switch. A system clock is incremented after each count: Sys Thr1 Thr2 1 1 2 1 3 2 4 2 ... 19 10 20 10 The average time for each thread to complete is 19 + 20 / 2, or 19.5. Now consider the example where thread 1 is allowed to run to completion before thread 2: Sys Thr1 Th2 1 1 2 2 ... 10 10 11 1 ... 20 20 Here, the average time for each thread to complete is 10 + 20 / 2 or 15. So, it costs 30% more work to let each thread run "concurrently" without factoring in any overhead from the actual act of task switching, which in my example was zero, but can never actually be zero. By increasing sys.setcheckinterval (the default Python value is 10!) we allow more work to be done by each thread before it yields control to another thread. The astute observer would also be able to note that the total system work for CPU BOUND processes can never exceed the speed of serial processing. Because Zope is primarily CPU bound, fewer threads tend to be better. I believe that a corollary to this is the effect people observe when Zope undergoes "superlinear" degredation -- ie, too many things get caught up in Zope (because too many threads are started). I am sure this isn't the *only* reason that happens (I dont have a good observation suite to analyze it). However, once internal queues for work build up in Zope, they are very difficult to dissipate -- you have to have a substantial lessening in the work arrival rate. N.B. If you use my figure of 1,000,000 bytecodes as a predictor of the Zope publishing path, you'll realize that this is about 5 cpu quanta (again using a quanta of 5ms) on a 1Ghz machine which is a Zope publishing rate of about 40 pages/sec. For some applications this is an optimistic value. For others, Zope can publish at a faster rate. This is not intended to cover ALL applications, just a 'good guess' at one. I suggest running 'ab' or similar against a representative sample of YOUR applications pages to convert pages/sec into a guesstimate of the "cost" of your application.
