Re: [Zope-dev] log levels
Florent Guillaume wrote: For instance the transaction code logs at DEBUG level every transaction start and end (self.log.debug(...)). This makes the logs very verbose, and any other code I write that logs at DEBUG level gets drowned in it. Previously transaction logs were at TRACE level but this doesn't exist anymore, and the python logging framework doesn't have anything between INFO and DEBUG or below DEBUG. Well, it supports numeric log levels, and you can define your own log levels too. I'd suggest the transaction code either logs at a numeric level: logger.log(-100,...) or we define another logging level for TRACE: import logging logging.TRACE = logging.DEBUG - 10 logging.addLevelName(logging.TRACE,'TRACE') ...which can then be used in the transaction code as follows: logger.log(logging.TRACE,...) cheers, Chris -- Simplistix - Content Management, Zope Python Consulting - http://www.simplistix.co.uk ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Re: [Zope] Testing products: Testing all in one batch
Paul Winkler wrote: Has anybody set up a batch job to test all installed Products in a zope instance? Yes ;-) Seems like the only *useful* way I can get it to run is with a loop that does bin/zopectl test once for each subdirectory of Products that I actually care about, taking care to ignore problematic third-party products. Which is OK I guess, but I'd prefer not to have to skip anything. I have a python script that builds a big command line to test.py of the form: bin/zopectl test Products/Product1|Products/Products2|etc ...it's not pretty, but it does work, and lets you exclude geb0rken products like Archetypes from test runs... - Some otherwise excellent third-party products have tests with dependencies that the product itself does not have, and which I do not want to install. (I will contact the author(s) privately.) Yep, I exclude them too ;-) - Some third-party products (e.g. CMF) ship with tests that just plain fail. Really? That's not been the case for a long time. When trying to test a Plohn setup, I found some of the Plohn tests were causing CMF tests to fail if the CMF tests were run in the same batch, 'cos they no doubt leave lots of crap lying around :-( If I install CMF 1.4.8 and nothing else, and run ./bin/zopectl test, I get 1 error and 1 failure. Why are you using something so ancient? ;-) - Some of my own Product tests run fine in isolation but break when run alongside other installed product tests. Then either your tests or the other tests are leaving turds... - Does this jibe with others' experience? Yes. - Is there a better (or best) way to run all my Product tests? If you find it, let me know! :-) - *Should* we expect that ./bin/zopectl test will run all installed Products tests, and if so, what can we do as a community to get authors to fix their products?

[Zope] Re: Presentations Available
Chris I agree that 2+ years should have produced maturity. Zope seems to be a lot more stable than Plone. Maybe the reason people focus on your Plone talk is you touch a chord with people who too are wrestling with Plone. Probably at least once a week the thought crosses our minds of ditching Plone and going back down to the Zope level, with some of our own stuff sitting on top of CMF. But then, Plone does provide some good things. If only these things would work consistently and not keep changing. Also while performance problems have been addressed in 2.1 there seem to still be migration problems and broken products which prevent people going to 2.1 yet. My colleague has spent a long time trying to migrate a Product he wrote, from Archetypes 1.2.5 to 1.3.4, due to the fact he had to hack around problems with references. My fear is as more features are added, what you describe as a shaky stack of complex fragile components will get ever more dependencies and therefore ever more complex and fragile. People often talk about the steep learning curve of Zope and Plone. When one is learning it, one tends to blame oneself for finding it difficult, and its a bad workman blames his tools. After a while though the question arises of why this seems to be harder to learn than say, some mathematical concept commonly considered hard to get your head around. The answer seems to be because its Plone's complexity and inconsistencies we are learning. This is not good and doesn't bode well for increasing mind share. This is not actually any worse than the J2EE / Java / class explosion world, but isn't one of the points of open source and collaboration that it should be much much better? It is great that so many people are willing to contribute their own free time, effort and resources, to write code that they freely share. It may well be that the quality of this code is miraculously good considering how its done by volunteers scattered geographically. That doesn't make the problems with Plone go away. It seems to me your recommendation to people to not use Plone at all, coming from someone who's been around in the Zope worldfor quite some time, is quite controversial but may in a roundabout way help if it forces people to make Plone more stable and mature. Well I guess I better don my asbestos clothing too. ;-) Regards Nick ___ 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] Upgrading from 2.7.6 to 2.8.1
Afternoon all, I'd like to upgrade our Zope/Plone/CMFPhotoAlbum/etc installation from 2.7.6 to 2.8.1. I'm having trouble performing the upgrade - I couldn't find any instructions on how to do it, and my attempt at a fresh install followed by a copy-over of the var and Products folders resulted in failure. Is there a document around that I've missed that describes what I should do? I'm also hoping that any help with this problem will indicate what the important files are in a Zope installation. This is because I need to make sure I have backups all sorted so that I can easily do a restore if/when the server goes bang. We're using Zope+Plone+others as our attempt at a new library, and so far the data weighs in at around 250 gig! The server is a HP ProLiant rackmount unit, driving a 8TB iSCSI storage unit, running Suse Linux 9.3 Pro.

Generally, to get a zwiki page to render itself programmatically, give it a REQUEST. Eg self.wiki.RecentChanges(REQUEST=REQUEST). In certain contexts you might still have skin trouble, in which case try self.wiki.RecentChanges(REQUEST=REQUEST,bare=1) to render without the skin.

Anyway, as somebody replied to me in zope-cmf list last night, the breakage is fixed on the 1.4 branch and there will likely be a 1.4.9 release. - Some of my own Product tests run fine in isolation but break when run alongside other installed product tests.

The problem is that tests seem to be run in alphabetical order, I don't know of a way to force another order, and so I'm left with adding and removing things from Products to see what minimal set of products will trigger the error - which is a crude technique since some products' tests will not run at all unless some other product is present (e.g. you can't run CMFDefault tests if CMFCore is not present). - Does this jibe with others' experience? Yes. Thanks.

We haven't succeeded in migrating to Plone2.1/Zope 2.8 but that is due to other problems with Archetypes migration.

Alec, Heh, thanks for the reply, I somehow have been using python for a few years now without ever running into that! I'm afraid I'm still baffled by it, mostly because I've used attributes named in such a manner up until now without problem ... From what you're saying I guess hasattr() being a built-in function, it's not recognized as part of the instance, so the mangling doesn't work right?

BUT, in my other situation, it isn't!! Heck, I think I even tried getattr(self, '__attribute') and it didn't work right. ONLY self.__attribute seems to work. But then, I'm back to wondering why the above works fine, and worry that something's going to come bite me later ... I'm starting to wonder if subclassing and/or my usage of metaclasses might be a cause for the different behavior?? Either that, or there's something buggy with zope's versions of get/set/has/delattr ... Even though I've gotten around it, I'll keep looking, it's driving me nuts :) J.F.

So hasattr(self, '__thumbnail') doesn't work as expected, but hasattr(self, '_thumbnail') DOES! (All other things being equal of course). This is actually a feature of python. Names starting with '__' are mangled by the interpreter so that they are not directly accessible outside the class itself; it is an attempt to simulate private class members. If you are finding yourself in need of using a variable that someone else has decided needed to be named with '__' then you may want to rethink what you are doing. It is somewhat rare that a python programmer would use this trick, so you should probably heed the warning and avoid using it if at all possible. If these are methods that you created then just rename them to use a single or preferably no underscores if you need to use them from outside the class itself (a single underscore is still bad form, as '_' is an indicator that a variable is intended to be private and a suggestion that it only be used in the class itself).

I see no problems with that. It doesn't matter one bit to the LDAPUserFolder (or the Zope security machinery) how many user records you have in the DIT. If there are any slowdowns as the number of user records increases it is most likely due to misconfigurations on the LDAP server itself, such as bad indexing or overcomplicateed/ unnecessary access control checks.

RE: [Zope] Re: Problem with hasattr() and Zope 2.8.1
Your example shows my problem, or what I see as a problem anyways: def __init__(self): self.__blech = 1 def do(self): print hasattr(self, __blech) x = Foo() x.do() False False? Really? hasattr() is used within the context of the class itself, so the fact it's private shouldn't be a problem, should it? If I was using hasattr() outside the scope/context of the class/instance, then ok ... But within it? I'm not breaking any privacy rules by doing this ... I'd expect the (un)mangling to be applied here. Of course, hasattr() is a standalone function ... So maybe that's a factor. Unintuitive behavior, I say ... Maybe I'll take this to c.l.p :) So how does an instance test whether it has a private attribute set? Is it really proper for to unmangle manually? (This would strike me as bad form when already working within the class/instance) So then that leaves me wondering why my other pieces of code DON'T do this, and work the way I initially expect ... No, my lang never ends in an _ ... It's always __attname_en for example, or __attname_fr ... Etc ... These are internal attributes wrapped by properties, though there is some metaclass trickery going on here as well ... Might be a factor? The fact some of the related logic (too long to show here, unless you're really interested) is dynamically bound through metaclasses maybe changes the scope of the attribute, and hence its mangling behavior? Basically I use something like the autoprop examples from the Python docs to do multilingual objects, where the language differences are handled at the property level (i.e. the getters/setters handle language differences). It's a pretty slick system if I may say so myself, works very well so far :) Just don't want my hasattr() to blow up in my face at some unfortunate time! Ah well, whatever it is, it's working ... I suppose I just don't understand why ... But this isn't a Zope problem I guess :) Thanks!

[Tim Peters] If you're using FileStorage, a technical detail in the implementation of the FileStorage index limits the maximum file offset that can be used to 2**48-1, or about 281 terabytes. Object IDs are effectively 64-bit integers (masquerading as 8-byte strings). [Andreas Jung] This would require how much RAM for the index? :-) Unfortunately, that's a complicated question -- the index is an OOBTree mapping 6-byte strings to a specialized kind of BTree mapping 2-byte strings to 6-byte strings. The complications add up. The good news is that if there are only two objects, say each consuming 128 terabytes, the index has only two entries and is actually very small wink. ___ 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 )
