Re: [Zope] Getting Properties of Objects in Folders Within
Max,
In response to your post here:
http://mail.zope.org/pipermail/zope/2005-February/156369.html
I am having some difficulty getting this to work.
###
# everything works fine from here
object = []
results = []
subbrain = []
query = 'somekeyword'
for brain in context.Catalog(meta_type='Folder',
bobobase_modification_time={'query':DateTime()-14, 'range':'min'},
PrincipiaSearchSource=query) :
# results.append(object)
path = brain.getPath()
print path
print ''
print '' + brain.title + ''
print ' + str(path) + ''
print '' + brain.description + ''
# ... through here
# however, what I'd like to do is get the path to every ExtFile contained
in these Folders
# this should get you every catalogued object in the folder
for subbrain in context.Catalog(path=path):
print subbrain.Title
print subbrain.Description
return printed
print '' + str(brain.date) + ''
print ''
return printed
Any additional help you could offer is appreciated.
John T.

ZEO may help. But may not help here, especially if you put your session
data in it. The main reason for read conflict errors are that a
particular transaction is "slow" and that other simultaneous
transactions come along and modify the data which the slow transaction
is trying to read. When the slow transaction figures this out, it bails
out. ZEO actually just makes it slower because the data involved in a
transaction typically needs to be encoded and decoded for travel across
a network. That said, if you have multiple appservers, and you keep
your session configuration as the default, each appserver will have its
own (non-ZEO)_ session database, and thus will presumably be less prone
to conflict due to the disbursement of sessions across multiple
machines. But you'll need to keep "session affinity" (every subsequent
request from a user with a particular browser id needs to go to the same
appserver). I use pound for this.
You should try to determine a pattern to the errors your users are
seeing (many simultaneous requests to a specific resource). This may be
better solved by changing application code to do fewer session accesses
or might be solveable via changing sessioning configuration.
See http://www.plope.com/Members/dunny/conflicts/view for an idea about
what sort of conflict rates to expect under torture situations.
Apparently your configuration has managed to torture sessions more than
our torture tests, however, because I've personally not managed to have
Zope try more than three times to complete a request that encounters a
sessioning conflict during this type of testing in the "default"
configuration.

Re: [Zope] ZODB.POSException.ReadConflictError
I have recently upgraded the server (see previous message about my current box) and that definitely has had a positive effect. I've also been tweaking the caches, to get the most out of what I have. The instances of these errors rearing their ugly heads are definitely down, but 10% error rate on 1,000 registrations per month still means a lot of me registering members manually. I'll explore the member registration process on the Plone list. Thanks for all your help here. Marshall On May 3, 2005, at 9:17 AM, Tim Peters wrote: ...

Re: [Zope] ZODB.POSException.ReadConflictError
Chris,
Thank you for that reference (I have an older dead trees version). Now
I understand that these errors happen, but what I don't understand is
why my users see them ("The requests which experience conflict errors
will be retried automatically by Zope, and the end user should *never*
see one." emphasis in original).
Is it simply a matter of too much traffic for the server? This is a
dual 2.3 GHz box, 2G of RAM, 10,000 RPM SCSI drives (two, mirrored as 1
logical RAID 1 drive), serving 8,000 members (now about 1,000 new
members a month, hence the urgency), 80,000 visits per month, 400,000
page views per month. Is it time to dip my toe into ZEO?

I've reproduced the error messages below, all of which resulted from a
member registration. I received 7 error reports were from the past two
days, with two types of errors. Of the two types of errors, the "oid

"oid 0x08, class Products.Transience.Transience.Length2" error was

twice.
Is there something wrong with my installation or is there something
wrong with my data.fs file? How do I correct either?

This is true. I misunderstood the OP inasmuch as I thought he was
seeing the error message in his event log, which would be normal It is
certainly the intent that end users should never see this error message
in a browser, but it's not a promise as it depends how the developer's
code is written. Zope will retry a request three times due to conflict
errors before it gives up and presents the conflict-caused error to the
user.

Conflict errors are certainly normal, but IIUC the OP is seeing site
errors, not just log msgs. The text referenced also says:
The requests which experience conflict errors will be retried
automatically by Zope, and the end user should never see one.
I'm not clear on why it says that, since Zope gives up after a few
tries (i.e., "never" seems an awfully strong promise, right?).

Re: [Zope] Problem with AdManager
How are calling the ads, as I don't think you need these two calls in a normal ad display. URL: /advert_chooser/manage_main URL: /site/advertisements/show_banner/manage_main Also: Try turning off "count views" and maybe "count clicks" and see if it does the same thing. It might be that Zope can't write to the ZODB that fast, although I run AdManager on about 10 sites in one Zope install that gets 20,000+ views (page) a day with no problems.

[Zope] Problem with AdManager
Hi Setup is: Zope 2.7.5, Python 2.3.5 (UNIX/gcc 2.95) (No ZEO, no CMF, no Plone!) We are trying to use the AdManager ZClass, a great product doing exactly what we needed. Testing this on the developer's machine, we had no problems. But having now done a "small scale" stress testing (requesting about 20 pages per second) on the server, some pages suddenly throw errors of the following kind (see traceback below). The errors are not all 100% like this one, but similar enough, I guess. The errors occur on a ratio of about 1:4 (so 4 successful pages, then one error). [I know this is not really scientific or would stand in a statistical analysis, but just to give you an idea.] We could also not find any connection between the errors and any of the 5 banners we're using for testing. (The product rotates which banner is displayed.) -- from the traceback -- ZODB.POSException.ReadConflictError Sorry, a site error occurred.

[Zope] applicable standards in zope
Hi, I'm making an study about different Python Web Framework and I need to know if there are any applicable standards in zope. If yes, which ones? Thanks a lot. Natalia. PD: I found this in http://mail.python.org/pipermail/xml-sig/1999-October/001537.html "Anyway, as for Zope (since I'm one of the product manager)" ... "I personally don't believe there are applicable standards for anything we're doing, and we follow where we can." ___ 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] [ANN] TextIndexNG 3.0 beta 1 released
I am pleased to announce the release of TextIndexNG V 3 beta 1. TextIndexNG V 3 is a complete new implementation based on Zope 3 technologies and can be used both in Zope 2.8 or 2.7 (with Five) or in Zope 3. What's new? - multi-field indexing and query support - multi-lingual support - configurable converters (through ZCML) - new indexing API (allowing you to hook your custom content types with TextIndexNG through Zope 3 adapters). Requirements: - Zope 2.8 or Zope 2.7 (+ Five) or Zope 3 (Zope 3 has nothing like catalogs yet) TextIndexNG V3 will *not* run with bare Zope 2.7 installations without Five (and this will not be changed in the future). Download: http://sf.net/projects/textindexng For installation issues refer to doc/README.txt from the archive. It's basically the same procedure as with former versions except you *need* to recompile the extension modules. TextIndexNG V 3 is published under the GPL.
