RE: [Zope] strange performance problem

Dennis, As far as resource problems go ... Did you check the swap ? Is it used, and if so by how much ? I was experiencing the same thing, only it would stop responding for up to several minutes, sometimes even long enough that I was just not willing to wait, so I had to restart it. I had 1GB of RAM, and the swap was holding 600-700K ... I surmised that maybe the waits occured when swapped out information had to be brought back or something ... So I added another GB of RAM, and now all problems have gone away. If that's not it, I'd look at increasing your thread count, maybe all your threads get locked long enough for the users to notice, due to long running actions ... The check interval could be looked at since you're on SMP. Since I had lots of spare CPU cycles, I set it to 0 myself, and that makes Zope very very responsive if you can spare the CPU power ... it's great! Python 2.3.1 and a beta zope also could be a problem, wasn't there issues/bugs with that ? Python 2.6.2 or 2.6.3 were officially support 2.1 ... I successfully used it with 2.2 for a while, but could never get it to run with 2.3.1 (Wouldn't even compile !). You might want to look into the 2.7/2.3.3 combo, it's been working very well for me as far as performance and stability. Good luck !

Users report that the system just seems to stop responding for a few seconds, then recovers. Of course, I've not been able to reproduce the problem nor isolate a command sequence that triggers it, but I am convinced that it's real. This, BTW, happens on a lightly loaded machine with no apparent resource problems. Any thoughts, pointers, or techniques to isolate the problem would be appreciated. Oh, yes, the environment..

Is FireFox usable as a WEBDAV client? If so, can someone suggest what I should read to get it working? -- John

I have checked the "plain text" box in the web client that I am constrained to using from this location) I'm not sure how Dragos meant for his suggestion to be implemented. I've tried different permutations of my code below, and to date have not succeeded in getting the database connector added as a child of my newly-added class. Here is my current code: class MyClass(mxmObjectManager.mxmObjectManager): 'This is the doc string' meta_type='my fake meta type string' id='MyClassInstance' def __init__(self, id): mxmObjectManager.mxmObjectManager.__init__(self, id) def manage_afterAdd(self, containter=None, content=None): self.manage_addZMySQLConnection( id='dbConnection', title = 'dbConnection', connection_string = configFile.DbConnString) def manage_beforeDel(self, container=None, content=None): pass def manage_addAction(self, id=PrinterSite.id, REQUEST=None): 'Add instance to parentObjectManager' mxmObjectManager.addClass(self, id, PrinterSite, REQUEST) Constructors = (mxmObjectManager.manage_addForm, manage_addAction,)

Search a Catalog in Python
by Andre Meyer 22 Mar '04

22 Mar '04

Dear Zopers This time, I thought it should be simple, but I am struggling again: The idea was to search for items that have been catalogued successfully. In the Zope Book they describe how to do this using form and scripts. That works for me, too, but then I need to search in a regular Python program (An FS product). For this purpose, I found the ZCatalog.search method and gave it a try, but I cannot get it to work. It expects a dictionary, but what does that contain? Here is what I have so far: __init__(self, id, title, ...): ... # add a Catalog _catalog = ZCatalog('Catalog') # add Metadata fields for the Catalog _catalog.addColumn('id') _catalog.addColumn('title') _catalog.addColumn('icon') # PathIndex _catalog.addIndex('path_index', 'PathIndex') # ZCTextIndex (with the required Lexicon) class Extra: """ Just a dummy to build records for the Lexicon. """ pass extra = Extra() extra.index_type = 'Okapi BM25 Rank' extra.lexicon_id = 'Lexicon' _catalog._setObject('Lexicon', PLexicon('Lexicon', '', Splitter(), CaseNormalizer())) _catalog.addIndex('title', 'ZCTextIndex', extra) # FieldIndex _catalog.addIndex('composer_first_name_index', 'FieldIndex', 'first_name') _catalog.addIndex('composer_last_name_index', 'FieldIndex', 'last_name') _catalog.addIndex('composer_year_of_birth_index', 'FieldIndex', 'year_of_birth') self._setObject('Catalog', _catalog) ... # all new items get catalogued (verified) and now we should be able to search for them like this (???): def searchForAnItem(item) obj=self.Catalog(id={'query':[item]}) What is wrong here? I feel very stupid again. Any help is appreciated! Thanks and kind regards Andre

It is exactly what it looks like: that user will not be authenticated unless the request originates in that domain.

configure '--prefix' or '--home'
by John Poltorak 21 Mar '04

21 Mar '04

It appears that when Zope 2.7.0 is getting built, any value for --prefix is being copied to --home and the latter variable used, and wondered why... Within the Makefile, is there any particular reason why '--home' is being used here:- ? install: build ${PYTHON} "${BASE_DIR}/setup.py" ${DISTUTILS_OPTS} install \ --home="${PREFIX}" ${BUILD_FLAGS} ${INSTALL_FLAGS} If this was '--prefix', as one might logically expect, it would build without any problems on OS/2. I notice that the Windows version includes '--prefix' at this point. I would like this to be changed to '--prefix' if the command line includes this option. Is that possible? -- John

In Zope 2.7, we're given a choice between C and Python. Could someone point me to a reference on what the difference is between the two? Thanks. Samir
