Re: [Zope] is it possible to upgrade from 2.9 to 2.13?
Does anyone have any further information on this bug in 2.10 regarding ZSQL methods? Would an upgrade from 2.9 to 2.10+ in an app using lots of zsql methods cause unforseen issues?

Re: [Zope] is it possible to upgrade from 2.9 to 2.13?
I can not tell for sure if the problem was that one of the aliases mentioned by Tres Seaver in results.py. However, I had a simple application displaying merely one page and involving a few tables and maybe 10 queries, and 2.10 could not even take hundreds of hits. I made a simple Python program to hit the web site on the same page and randomly changing the parameters. In my experience, if you cook up some simple testing like this you'll quickly see the leak (I was using top in Linux).

Re: [Zope] is it possible to upgrade from 2.9 to 2.13?
Stefan, thanks for your reply. In the meanwhile I was indeed able to put products in INSTANCE/Products (Zope 2.13.8). I did not know about that option you mention and I cannot check it now, but the Products from pypi were being recognised, as long as I put only the specific Product subfolder (not the whole pypi package which contains cruft for eggs, whatever else, I still don't fully understand). However, with ZSQL Methods, the situation is different. It contains the specific ZSQL Methods folder, but also Shared/DC/ZRDB. When loading, Zope complains it can't find the module ZRDB/Search.py (or something like that). So, ZSQLMethods depends on Shared, but Share is not being recognised (or at least not yet processed before ZSQL). How can I fix this? Somehow I guess the pypi package should be made an egg and dropped in lib/python2.6, and somehow configured. I couldn't yet find instructions on doing this for Zope. I've been trying to read about this whole new procedure[s] (setup tools, buildout, eggs, virtualenv, ???), but I have the impression the situation has been changing and it's quite hard to figure out what makes sense or works right now.

[Zope] is it possible to upgrade from 2.9 to 2.13?
[resending as original seems to have got lost] I got stuck with 2.9.9 because 2.10 introduced a major leakage in the ZSQL Methods. Now the number of users in my web site have increased and other leakages have become also major issue (e.g., PageTemplates.Expressions.SubPathExpr). I was considering a major upgrade to 2.12 or 2.13 and I was trying 2.13.8. However, how can I install products?? It states in 2.12 What's new that they are still working but in fact merely dropping Products in the site-packages does not add a product.

I found in Catalog.py updateMetadata around line 306

the if condition evaluates always to false, cause the data.get(index,0)

Zope was not restarted that worked fine.
The code above should prevent a write (which would grow the storage)
when in fact nothing changed. And it looks correct.
Yes, but it does not work as exspected.
Here is a more detailed description of our usecase:
In our catalog we have a keyword index registered_courses and a
metadata field registered_courses. If a student registers a new course
an event is triggered, which adds the new course to the index. In our
event-handler we have:
res = students_catalog(id = student_id)
if not res:
return
student_rec = res[0]
registered_courses = getattr(student_rec,'registered_courses',None)
if not registered_courses:
registered_courses = []
#import pdb;pdb.set_trace()
if event_type == sys_add_object:
if course_id not in registered_courses:
registered_courses.append(course_id)
else:
return
elif registered_courses and event_type == sys_del_object:
removed = False
while course_id in registered_courses:
removed = True
registered_courses.remove(course_id)
if not removed:
return
record_data = {}
for field in self.schema() + self.indexes():
record_data[field] = getattr(student_rec, field)
# Add the updated data:
record_data.update(data)
self.catalog_object(dict2ob(record_data), student_id)
where dict2obj does just that.
That updates the meta_data only on index_creation, and after a zope
restart the meta_data for registered_courses only contained the first
added course. That was because (i asume)
data.get(index, 0) always got the data from the index, and not from the
meta_data. I could veryfy this by looking at the catalog-record in the
ZMI. So it neve got to update the meta_data, so the real cause for
this problem is that data.get(index, 0), returns the value of the index
here and not that of the meta_data.

[Zope-dev] Re: Possible Windows Service improvements.
Mark Hammond wrote: Would a lockfile work ok to signify running state? IOW, Zope would lock a file as one of the last steps during startup (which it actually does now, but might do it a bit too early). The Windows service manager would attempt to lock the same file after timeout seconds (although I'm not sure where to get timeout from) on initial startup. If the file doesn't exist or the lock succeeds, the process is nonrestartable. If it exists and cannot be locked (Zope has locked it, signifying successful startup), the process is restartable. This lets the parent know of successful startup, but doesn't help it during the 'starting' phase (if the lock never gets set, how long do we wait before giving up?) Ditto for shutdown - after requesting the child shutdown, how long do we wait for it to terminate? A single timeout leaves us where we started - it is too fragile to assume that if the app has not started after x seconds, it never will. By having the child actively report progress, the parent process can be more confident it is alive and normal, even if it is taking a very long time to start. Wouldn't a socket work? As the parent process is starting the child, it could pass the port on the cmdline. I think by *describing* the API, I made it sound more complicated than it is. It consists of 2 functions: def reportState(state, timeout, error_info = None): Called by the child process, and implemented by the parent. Reports the status of the child process to the parent. state may be 'starting', 'running', 'stopping', 'stopped', 'pausing' or 'paused'. timeout is how long before the parent will consider us dead if we don't report progress again. error_info may be specified as the program reports 'stopped'. If None, the shutdown was normal. # This second one is optional, but abstracts away using signals :) def changeState(new_state): Called by the parent process, and implemented by the child. Requests that the client process enter the specified state. Only 'running', 'stopped' and 'paused' are valid (ie, the parent must never request any of the transition states) If we ignore the second and stick to signals, it seems fairly robust and achievable. The other option is that we get rid of the 'parent' service all together. Just have the service code use run.py directly, and run it in-process. The Windows builtin 'auto-restart' facilities for services can handle the bizarre errors, and offers the benefit of allowing the user to define the restart policy (even allowing them to reboot should it go down wink). There may be good reasons for that though. I still think we should look at making a Windwos version of the 'zdaemon' handler, which uses a Unix-domain socket between parent and child: we could either use a named pipe on Windows, or else a socket on localhost, to achieve the same ends.

[Zope] Is it possible to use regular CGI's like htDig with zserver?
I've been fooling around with htDig as a method of searching both my dynamic pages and older static pages, on two different sites, and it works great, since it's a 'spidering' search engine But since it is running on the same machine as my Zope install, while experimenting with it, I've had to run it on port 81, using a dedicated instance of Apache. I realize that the "right" way to do this would be to run Zope as a CGI and use Apache as the server, but since the performance of zserver has been quite good I wanted to ask this. I know that Zope can serve pages put of the filesystem. (i.e. act as a standard web server in some ways) Can it also avail itself of the services of Apache-compatible CGIs, notably htDig?

[Zope-dev] ZPatterns; possible bug?
I have a specialist "Instructors".
It holds a rack, containing DataSkin-derived ZClasses of meta-type
"Instructor".
The Instructor class has a DataSkin Attribute propertysheet called
"Basic", and this has properties for forename, surname, address, areas.
I have some skinscript in the Instructors specialist:
WITH SELF COMPUTE
name='%s %s' % (forename, surname),
areas_comma_sep=_.string.join(areas, ','),
address_lines=_.string.join(address, '\n'),
address_comma_sep=_.string.join(address, (', '))
WITH SELF COMPUTE
__roles__=_.None
# XXX publicly visible!! Nutter!!
# change __roles__ to ('Operator',) later.
This works fine. The __roles__ bit is a hack to make Zope 2.3 ZCatalog
play nicely with the Specialist and __bobo_traverse__.
I have some other skinscript that keeps an instructors index in a
ZCatalog inside Instructors.
WHEN OBJECT ADDED CALL
Catalog.catalog_object(self, _.string.join(self.getPhysicalPath(),'/'))
WHEN OBJECT DELETED CALL
Catalog.uncatalog_object(_.string.join(self.getPhysicalPath(),'/'))
WHEN OBJECT CHANGED CALL
Catalog.uncatalog_object(_.string.join(self.getPhysicalPath(),'/')),
Catalog.catalog_object(self, _.string.join(self.getPhysicalPath(),'/'))
This worked fine.
When I changed the first skinscript to make one WITH SELF statement, I
got some strange inconsistencies:
WITH SELF COMPUTE
name='%s %s' % (forename, surname),
areas_comma_sep=_.string.join(areas, ','),
address_lines=_.string.join(address, '\n'),
address_comma_sep=_.string.join(address, (', ')),
__roles__=_.None
On changing an instructor's properties using manage_changeProperties on
its propertysheet, I'd see the change in the instructor. However, the
ZCatalog metadata would always have the most recent value for "surname",
but the last value for "name".
Changing the skinscript back to using two statements makes cataloging
function normally again.
I could tell when the catalog was doing by instrumenting the recordify
method of Catalog.py:
def recordify(self, object):
""" turns an object into a record tuple """
print "recordify %s" % (object)
record = []
# the unique id is allways the first element
for x in self.names:
try:
attr = getattr(object, x)
if(callable(attr)):
attr = attr()
except:
attr = MV
print " appending %s:%s" % (x, attr)
record.append(attr)
return tuple(record)
A typical (wrong) debug output would be:
recordify Instructor instance at 86c16b0
appending id:instructor-977678608
appending meta_type:Instructor
appending bobobase_modification_time:2001/01/04 17:26:01.35408 GMT
appending name:Bob Collins8
appending surname:Collins9
appending areas_comma_sep:M12
This is after changing the surname of the instructor from "Collins8" to
"Collins9".
The cause of the problem? I don't know. Maybe I'm doing something silly.
I think what is happening in the broken example is that when the zope
security machinery asks for __roles__, name is also computed. The
machinery must request __roles__ before changing anything.
After that, surname gets changed. However, changing "surname" only
invalidates "surname" in the cache; not anything that is computed using
surname.
At the end of the transaction, when the triggers are called, name is
already in the dataskin's attribute cache, so it does not get recomputed.
In the working example, when __roles__ is requested, it is in a
different skinscript statement, so it does not cause "name" to be
computed. Thus, "name" can be computed freshly after "surname" is set.
Is this behaviour intended, is it a bug, or is it an unimplemented feature?
Thanks.

Re: [Zope] is it possible to import from Excel
When on a windows platform, I prefer to define an ODBC datasource on the excel spreadsheet, write ZSQL method that selects the fields to be imported, write a DTML method that iterates on returned records and call another ZSQL method that writes into Gadfly. You may need to handle None/Missing values to prevent from ending up in gadfly as 'None' etc. If your not want to be tied to ODBC and Excel on the deployment platform, you can always try saving the content of the Excel sheet in a text format, if that is possible for your kind of data? The text file could then be parsed by at external method or even imported to the TinyTable product. On lage amounts of data this could be quite time consuming. So it would probably be more efficient to write a seperate import program. There might even be one for Gadfly. In that way you don't have to use a "unreliable" HTTP connection when importing data.

Re: [Zope] is it possible to see whether any user is using a perticular zope object
hi,
when I use the DTML method which include call to SQL methods,
if someone is also using that DTML Method then either of us get the error
message. And the error message is as follows.
Error Type: SyntaxError
Error Value: unexpected token sequence.near :: "\012Q_name = 'q24'"*''
*** current state = 231 expects: 'EXCEPT', '+',
')', 'HAVING', '-', 'UNION', 'AND', 'GROUP', '*', ';', 'OR', 'ORDER',
'INTERSECT', ('nomatch1',) current token = ((-6, 'WHERE'), 'WHERE')
I would like to avoid that error, instead of that I would like say 'wait '
or something like that. and after the first one gets the complete page the
other's page should come.
Can u give any suggestions.
thanks

It sounds more likely that your SQL has problems. Perhaps you could post

That is why when more than one users try to access the same DTML method only one will be able to continue , others will get the error message. thanks yours, K.H.Subrahmanyan ( [EMAIL PROTECTED] ) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev ) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

No, I haven't used any other DBMS. I have almost finished working in this gadfly. So I can't change now. Because there is no time to change it now.

Re: [Zope] is it possible to see whether any user is using a perticular zope object
In reality changing the dbms shouldn't cause too many problems (I'd give it a day to get the conversion done myself). Try MySQL or Interbase as they work fine on Win32 (which if I remember correctly is what you use?)

RE: [Zope] is it possible to see whether any user is using a perticular zope object
Hi, Same as you, i tried to use this gadfly thing when I started and even when choosing it I received a message from zope telling me that it wasn't the real thing/unreliable/etc. I *think* there is a more stable GadFly somewhere but I would advise you to go with mySQL which I use and never had any problems with. Unless I'm wrong, it wouldn't be such a pain to change to mySQL or other DBMS... You would only have to dump the content of the current DB and create the tables, if necessary. mySQL's learning curve is not that big and is faily easy to understand/use/get used to.

[Zope] is it possible to see whether any user is using a perticular zope object
hello , I am subrahmanyan. I am using zope for my project. Now I would like to know is it possible to know if any body is using the zope object. I mean , if one user is running one DTML method , Iwant to know that one user is using that object. Is there any DTML tag for that. thanks. bye yours, K.H.Subrahmanyan ( [EMAIL PROTECTED] )
[Zope] is this possible?

[Zope] WorldPilot 1.1.0 - Possible bug and solution ?
Hi Zopers, apparently, WorldPilot has an error in the getIMAPFolders function, that do not allow the creation of folders. The line is the following: cf.AddChild(IMAPFolder(Folder,TmpFolderFullName[:-1] , padding+Folder)) I have changed it in: cf.AddChild(IMAPFolder(Folder,TmpFolderFullName[1:] , padding+Folder)) and now I can happily create folders and move messages around. I am using courier IMAP on a Red Hat Linux. Can someone confirm the patch ?
