RE: [Zope] developing with zmi: how to move a patch from data fro m devel to live?
You can manually export objects from your dev zope to individual files and then import them back to the live instance through ZMI. You could try this : http://zsyncer.sourceforge.net/ It will enable you, for built-in Zope object types (but then you can extend it with your own types) to list the differences between your dev and live zope instances and deploy your changes.

The problem is that you develop using the ZMI. It's a bad pattern. Don't do it. well, it's the opposite. i (our company) don't develop using the ZMI. i'm using an install script. so when we install our program, no gui editing is needed. but last week i've seen a presentation which used a CMS system called Typo3. and a guy showed us how he can build a CMS only with gui tools. it was very fast and effective. and then i thought.. wow, you can work sooo fast in typo3. and we're so slow to develop with zope (plone/cmf/whatever). and then i remembered. but wait, we don't use the gui tools (zmi) at all! maybe we should! an example: for the next version of the program, we decided to change an action what happens when you click on a TAB in the CMS. in gui, i would do it like this: go to the portal_actions object, find the correct tab, change the python-script associated to it. but we had to dig thru the source code, to find out how the ZMI does it, and follow the same process when we did it programmatically in the python install script. it took us let's say 4-5hours (partly because that part of the CMF was badly documented, and used a quite inconvenient way to handle that) compare that: 1minutes in the ZMI or 5hours in a python-script. which one is better? well, or let me ask the question a different way: if i should not use the ZMI, then why is it there? gabor ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] ZODB error when trying to index object (Input/output error)
Hi
I get the following error when certain new objects are added into a
plone site - when archetypes tries to set the UID, it asks the catalog
for all unique values of the index "UID". I;ve never had input/output
errors before from the ZODB. There's definitely enough space on the
drive and objects are added fine - it's just that the UID is then not
set, which breaks all sorts of Archetypes stuff. Any ideas how I can
hunt this one down?
Thanks,
Felix.

RE: [Zope] custom_persist_obj
You have a built-in Zope object for this : PersistentMapping.
dict1=PersistentMapping({'a':1,'b':1,'c':1, ...})
dict1=PersistentMapping({'a':2,'d':4,'e':6})
The only thing you can not do compared to dictionaries is :
for key in dict1:
do something
(you need to use for key in dict1.keys():...)

Re: [Zope] custom_persist_obj
Well, sure. But you need to write some unrestricted (i.e.
filesystem-based) code if you want to create instanced of
PersistentMapping and the like.
by the way, if it's ever going to get large, you might look
into using OOBTree instead of PersistentMapping.

This IOError typically indicates a rights problem at the filesystem
level. I could also be a full-disk problem or maybe a file corruption.
Check the OS-level stuff first, and then try the usual ZODB
check/recover stuff.
I don't think this is relevant, but it may be useful:

This means that your storage file cannot be read.
Maybe, it was closed...
I think, I saw similar behaviour in our ZEO server
when it was shutdown while it was performing an operation
in a separated thread ("undoHistory").
The shutdown signal caused the storage to be closed but
the separate thread still tried to access the storage.

This is possible as long you have a strict separation between content (created on the life server) and infrastructure (created in the develoment system). Configuration may be partly controlled in the life and partly in the development system. In this case, you need again a strict separation between these worlds. If this separation respects object boundaries (i.e. no updatable object contains both life and development controlled parts), then you can use Zope's export/import mechanism for the synchronization. The use of "export/import" can be automated as demonstrated by "ZSyncer" (others already suggested this solution). "ZSyncer" integrates a local export and the corresponding remote import in a single Web transaction. However, knowing your application, you can integrate such exports and imports for all your development controlled objects. If the separation crosses object boundaries, you cannot use export/import (as it would vipe out the life controlled parts of the object). We extended the basic "ZSyncer" mechanism to also synchronize partial objects. It essentially works by defining "_zsyncer__getstate__" and "_zsyncer__setstate__" methods that extract and import partial content. @Paul: let me know if you are interested in this ZSyncer extension. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] accessing session data error
Hi all:
I
think that I found a ZOPE bug. Is really very important for me know what can
I do for avoid it. The first 9 steps are to recreate the situation and the
other steps are to provoke the error.
Step 1: Crate a folder called "reproducingError" in Zope Interface
Manage
Step 2: create a page template called "index_html" in the "reproducingError"
folder with the following content:" "
Step 3: create a python script called "init" in the "reproducingError"
folder with the following content:"# init scriptsessionData =
container.REQUEST.SESSIONsessionData.set("userId",
container.REQUEST.user)
return context.init2_html()"
Step 4: create a page template called "init2_html" in the "reproducingError"
folder with the following content:"passing face 2"
Step 5: create a python script called "init2" in the "reproducingError"
folder with the following content:"# init2 scriptrequest =
context.REQUESTsessionData = request.SESSION
sessionData.set('idService', 'testService')
context.first()return context.external(context)"
Step 6: create a page template called "first_html" in the "reproducingError"
folder with the following content:"First Response"
Step 7: create a python script called "first" in the "reproducingError"
folder with the following content:"# first scriptresponse =
container.REQUEST.RESPONSEstr = container.first_html()
response.write(str)response.flush()"
Step 8: create an external method called "external" in the
"reproducingError" folder with the following content, in where the function
of the external method is "communicationResponse" and the module is any name
that you give to the file:"# external methodimport time
def communicationResponse(context):
response = context.REQUEST.RESPONSE
sessionData = context.REQUEST.SESSION strDetailEnd =
"window.location='reproducingError/end'"
for item in range(1, 40):
time.sleep(3)
response.write("Response
iteration:" + str(item))
response.flush()
response.write(strDetailEnd)
response.flush()"
Step 9: create a python script called "end" in the "reproducingError" folder
with the following content:"# end scriptidService =
context.REQUEST.SESSION['idService']
return "Fin - " + idService"
Step 10: open two explorer in wich call the object "reproducingError"
(Example: localhost:8080/reproducingError)
Step 11: enter an example text in each one.
Step 12: clink in the link of one of them, and 5 second later clink on the
link of the other explorer. The waiting for around 5 second is necesary
because with other time interval not allways get the error.
Stpe 13: and wait the "Response iteration"... Please if the error
don't appear in any of the pages, begins at Step 9 again. and try to count
to 5 witch other velocity :)
The correct result is:"Fin - testService"
The error is:"
Site ErrorAn error was encountered while publishing this resource.
Error Type: KeyErrorError Value: 'idService'"The traceback:
"Traceback (innermost last): Module ZPublisher.Publish, line
101, in publish Module ZPublisher.mapply, line 88, in mapply

I
will appreciate if you try until the error appear, because I not always
obtain the error. I thinks that it is bacause the time interval between the
two request.
A
curious thing is that when I obtain the error, if I wait around 15 second
and refresh the page in wich i obtain the error, the correct result appear..
and no errors come.
Sorry for the extended message, but I need any help that you can give me,
because this describe error environment imitate a funcionality that I must
give in a system very import that i'm doing.
I'm using Zope 2.7.6 for Windows.
Thanks in advanced.

[Zope] ZMYSQLDA 2.0.9 lock problem
IE, Zope 2.7.6, Python 2.4.1, MYSQLDA 2.0.9 One of our developers is reporting a curious problem, which I have not been able to track down. It appears to be threading related, somewhere in the ZBMYSQLDB adaptor. The database connection string is bare of transaction indicators. The database is local. All tables are MyISAM which is non-transactioal. Unfortunately the user does not remember the exact sequence of events which generate the problem so I am unable to duplicate. What we do know is that the problem occurs at the beginning of a development session begun with a cold boot of the client machine and a fresh browser and it occurs once and only onece during the development session. The developer normally has two active Zope threads going--one working with the application and one working with the ZMI. He moves between them using the Open/View tab and other buttons. He reports that the first time he moves focus from the ZMI to the application, he gets the following error: --- Time 2005/06/20 07:12:03.478 GMT-7 User Name (User Id) (X) Request URL http://xxx..com/logged_in Exception Type error Exception Value release unlocked lock Traceback (innermost last): * Module ZPublisher.Publish, line 107, in publish * Module Zope.App.startup, line 222, in commit * Module ZODB.Transaction, line 260, in commit * Module ZODB.Transaction, line 377, in _finish_many * Module Shared.DC.ZRDB.TM, line 59, in tpc_finish * Module Products.ZMySQLDA.db, line 376, in _finish error: release unlocked lock The lock being released is a transactional lock. None of our locks should be transactional locks, given our setup. I traced through the __init__() method for DB and did not see how transactional locking could be specified so the lock relaease code could run--I must be missing something. No thread in our system uses transactional locking as the tables do no support transactions. The logged_in method references the MySQL database in several places; a couple of them are compound queries where multiple queries are joined by "" values. Many of our queries use this in combination with the "use " SQL query. The system is using ZODB filestorage (Data.fs) with ZEO and is pretty much out of the box. Has anyone else encountrered a similar problem. Any suggestions as to how to find this bug? ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] Problem with keep-alive timeout
I made a small and simple database applikation with some reports on a large database. But surprise, IE 6.0 (WinXP,SP2) is getting always a timeout after 60seconds, because IE communicates with Zope through the HTTP1.0-protocoll. My reports needing always 40s-120s, so is there someone that could give me a solution for this annoying timeout problem? ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Problem with keep-alive timeout
I had a similar problem and solved it by having a cron job that runs in the background with wget. In my case was able to divid it up to run a little bit of the big report at a time.

Re: [Zope] accessing session data error
Hi Leticia,
Thanks for the detailed bug report.
I have tried to replicate the bug as you indicate below but cannot.
I've gone through the process you describe ten times without errors (in
Zope 2.7.6).
If it's possible to simplify the steps to recreate the error, that would
be helpful in further debugging (for example, maybe just getting rid of
all the page templates and python scripts and just using a single
external method).

Re: [Zope] accessing session data error
Hi:
Thanks for the rapid aswer of Chris McDonough. I will change the
steps to replicate the error (sorry for the large steps before :( , I thinks
that maybe was needful). Remember that the key of the error is the time
interval between the request. If with 5 seconds don't appear the
error try to vary to other, like 7 seconds. The 5 first steps are to
create the situation and the sixth step are to provoke the
error
Step 1: Create a folder called "reproducingError" in Zope Interface
Manage
Step 2: Create a srcipt "end" with the content:
"
# end scriptidService = context.REQUEST.SESSION['idService']
return "Fin - " + idService"
Step 3: Create a script "index_html" with the content:
"
# init scriptsessionData = container.REQUEST.SESSION
sessionData.set("userId", "userExample")return context.init2()
"
Step 4: Create a script "init2" with the content:
"
# init2 scriptrequest = context.REQUESTsessionData =
request.SESSIONsessionData.set('idService', 'testService')return
context.external(context)
"
Step 5:create an external method called "external" in the
"reproducingError" folder with the following content, in where the
function of the external method is "communicationResponse" and the module is
any name that you give to the file:
"
# external methodimport time
def communicationResponse(context):
response = context.REQUEST.RESPONSE
sessionData = context.REQUEST.SESSION
strDetailEnd =
"window.location='reproducingError/end'"
for item in range(1, 40):
time.sleep(3)
response.write("Response
iteration:" + str(item))
response.flush()
response.write(strDetailEnd)
response.flush()
"
Step 6: open two explorer
In one of them call the object "reproducingError" (Example:
localhost:8080/reproducingError), then wait 5 second and put in the other
the same direction.
And wait the iterations
Note: I count 5 second, not with chronometer. You can try
with a near number.
Chris: I reproduce the error with the steps. I can't reduce it to an
external method. Thanks again.
The error that I obtain is the same:

I must solve this, because this is part of my thesis for university
graduation. Any help will be appreciated.

Hi:
Thanks for the rapid aswer of Chris McDonough. I will change the
steps to replicate the error (sorry for the large steps before :( , I thinks
that maybe was needful). Remember that the key of the error is the time
interval between the request. If with 5 seconds don't appear the
error try to vary to other, like 7 seconds. The 5 first steps are to
create the situation and the sixth step are to provoke the
error
Step 1: Create a folder called "reproducingError" in Zope Interface
Manage
Step 2: Create a srcipt "end" with the content:
"
# end scriptidService = context.REQUEST.SESSION['idService']
return "Fin - " + idService"
Step 3: Create a script "index_html" with the content:
"
# init scriptsessionData = container.REQUEST.SESSION
sessionData.set("userId", "userExample")return context.init2()
"
Step 4: Create a script "init2" with the content:
"
# init2 scriptrequest = context.REQUESTsessionData =
request.SESSIONsessionData.set('idService', 'testService')return
context.external(context)
"
Step 5:create an external method called "external" in the
"reproducingError" folder with the following content, in where the
function of the external method is "communicationResponse" and the module is
any name that you give to the file:
"
# external methodimport time
def communicationResponse(context):
response = context.REQUEST.RESPONSE
sessionData = context.REQUEST.SESSION
strDetailEnd =
"window.location='reproducingError/end'"
for item in range(1, 40):
time.sleep(3)
response.write("Response
iteration:" + str(item))
response.flush()
response.write(strDetailEnd)
response.flush()
"
Step 6: open two explorer
In one of them call the object "reproducingError" (Example:
localhost:8080/reproducingError), then wait 5 second and put in the other
the same direction.
And wait the iterations
Note: I count 5 second, not with chronometer. You can try
with a near number.
Chris: I reproduce the error with the steps. I can't reduce it to an
external method. Thanks again.
The error that I obtain is the same:
"

I must solve this, because this is part of my thesis for university
graduation. Any help will be appreciated.

[Zope] installation problem
Hi-
I got zope 2.8 installed on fedora core 4. Whenever I execute this
command to start zope /usr/local/zope/instance/bin/runzope, I get this
error:

For help, use /usr/local/zope/lib/python/Zope2/Startup/run.py -h
I noticed that this affected other people from some discussions, but I
couldn't find any solution. Does anybody have an idea where I can
start? My buddy got his working on fedora core 4 fine, so it shouldn't
be a problem. When I first compiled zope, I used this command.
"./configure --prefix=/usr/loca/zope --with-python=/usr/bin/python2.4".
Any help would be much appreciated!

Re: [Zope] accessing session data error
Hi Leticia,
The mixture of ``response.write()`` including JavaScript to drive the
browser to a new location along with writing objects in ZODB all
within the same transaction can break some of the promises that you'd
normally expect Zope and a browser to keep.
My guess is that browser is being told to visit ``end`` before the
transaction started by ``init2`` has finished. Perhaps a conflict
error is causing that transaction to take longer than you expect.
Normally this would not trip you up as your browser does not see
anything until after the transaction has finished. (In this normal
mode you might see a conflict error rendered in the browser if the
publication machinery had to give up.)
For your example try breaking up ``init2`` into two scripts. The
first that writes the session data and then redirects the browser to
the second. The second then does not touch session data and manages
all the ``response.write()``s. And remove the unused ``sessionData =
context.REQUEST.SESSION`` from ``external``.
Cheers
Michael

Try to compile Zope with a *fresh* Python 2.3.X installation and not with
the FC4 Python. 2.4 is btw. not supported as documented and and as posted a
hundred times.
