Understanding 2.7 Product import
by Erik A.Dahl 18 Feb '04

18 Feb '04

Ok 2.7 has an instance/Products directory. What magic is letting them be imported? I'm running a bunch of data loader scripts that create persistent zope products. I have found that: import Globals sets things up so that my data loader scripts can import products properly (even though their path is not in sys.path). I looked around in Globals to figure out what's going on and didn't find it. It would be nice if something in: import Zope. would kick off the special import magic! It seems a lot more intuitive to have this at the top of the __main__ script instead of Globals. -EAD

app = Zope.app() backwards incompatibility notice / discussion
by Chris McDonough 16 Feb '04

16 Feb '04

The extant "import Zope; app = Zope.app()" dance to get a hold of the Zope root object stopped working long ago on the 2.7 branch and HEAD due to the new configuration machinery, which implies that users be explicit about configuration settings rather than allowing Zope to guess. Up til now, the dance to get Zope 2.7 to start properly from within a script was byzantine and obscure. I've made a checkin which makes it a little easier (or at least I'm about to as soon as the full unit test suite comes back passed ;-). Code which used to do: import Zope app = Zope.app() Will need to do this under 2.7b4+: import Zope Zope.configure('/path/to/configfile') app = Zope.app() (I wont bother telling you what the dance was for 2.7 before now, it was pretty awful). I realize this is suboptimal from a backwards compatibility perspective, but I'm not sure how to make it any better, seeing as the config file has some fairly important information in it (like which databases to use) and guessing would be very bad in this context. Jim Roepke suggested that if an "ZOPE_CONFIG" envvar was set with the config file path, that "import Zope; Zope.app()" could be made to "just work", but I'm not sure this is any better than requiring that developers change their scripts. Guessing at the config file location is also fraught with problems, and I'd be hesitant to do it. I'm apt just to recommend that we require that developers add the "Zope.configure(filename)" line to their scripts as opposed to doing anything more magical. I'm sure there will be indignant wails about it, but c'est la vie. ;-) Note that FWIW, you can also do (on UNIX): zopectl run <scriptname> .. which will run a script with the name "app" set up as the root Zope application object. This might be the easiest way to run scripts which need to operate against Zope objects going forward. - C

Re: restrictedTraverse doesn't give the good container

Hi, > Please don't cross-post. > You already posted this exact question to zope@[...].org, > and received two replies to which you did not follow up. Sorry if I did that, but my Webmail gives me some trouble, and you've certainly knew it because you can't reach my box. > Why should we have time to fix your problem when you > apparently don't have time to respond to our replies? I don't ask for someone to fix my problem, just to know if someone had fixed it before. I have no time to have a look yet, but if nobody had fixed up, I will fixed up later. Incidetn is closed. Just for the answer fo the link below : http://aspn.activestate.com/ASPN/Mail/Message/zope-List/1993724 No the path is not absolute. I have this hierarchy : -Root --ThisFolder ---FolderA ... I've written as: ... thepath = 'ThisFolder' path = context.restrictedTraverse(thepath) ... To follow the folders I've written: ... herenow = context.restrictedTraverse(path+'/FolderC') herenow = herenow.restrictedTraverse(path+'/FolderC') ...

Options problems with 2.7 and Zope.configure("/instance/etc/zope.conf")
by Erik A.Dahl 14 Feb '04

14 Feb '04

I'm moving a bunch of scripts that do the import Zope, app=Zope.app() dance to 2.7. I added the configure call and things were find until I ran a script that had positional arguments. This gave me a "ERROR: positional arguments are not supported". This comes from zdoptions.py:226. Basically zdoptions.py is parsing sys.argv. I don't think it needs to do this from the Zope.configure call since it is getting the config from zope.conf. We could prevent the sys.argv parse by passing changing lib/python/Zope/Startup/run.py:39 to: opts.realize(args=[], doc="Sorry, no option docs yet.", raise_getopt_errs=0) It looks like all that zdoptions.py is looking for in sys.argv is its configfile. Since we passed this in to Zope.configure it doesn't seem nessesary. Would this mess other stuff up? I don't want zope parsing my script options! -EAD

2.7.0 corrupt Data.fs
by Thomas Anderson 14 Feb '04

14 Feb '04

I'm seeing changes to the ZODB getting lost on reboot. I think it's because there are no fsync() calls being issued by Zope or even by zopectl on stopping Zope but I can't be sure. I'm using /instance/bin/zopectl {start|stop} for controlling Zope. I added a "sync" command to my /etc/init.d/umountfs script (Debian Woody) and this seems to have fixed the problem. I know postgresql syncs to disk for every transaction by default, does Zope? Tom

TypeErrors during 'make test'
by Evan Simpson 13 Feb '04

13 Feb '04

I'm getting several TypeErrors when I run 'make test' on the HEAD. Each of them involves a call to cAccessControl's 'validate' with 'roles' set to a PermissionRole instance, complaining that it's not iterable. Any ideas? Cheers, Evan @ 4-am

This is a good time for people who care about packaging to get involved ;)

This would be a good time for people interested and knowledgeable about packaging systems and who want to influence the direction we take with Zope 3 to get involved. :) Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

Strange loop with ZCatalog
by Pascal Samuzeau 13 Feb '04

13 Feb '04

Hi, For some tests I have done : - Create about 5000 folders under the Root Zope Site - Inside those folders, I have created about 30 000 objects ( as document, just an id, title and a Type). - I've catalogued all inside a catalog named TheCatalog I have written just this function, in intend to test my CPU ( that why I've written it like this): allobject = context.TheCatalog.searchResults(Type='TypeTest') l=len(allobject) i = 0 #for i in range(len(allobject)): for object in allobject: #path = allobject[i].getPath() #course = allobject[i][0] path = allobject.getPath() course = allobject[0] thepath = string.split(path,'/') lepath = string.join(thepath[:-1],'/') lieu=context.restrictedTraverse(lepath) lieu.manage_delObjects(course) i+=1 return "Len: %s and Number parsed: %s" %(i,l) Phase A: I have 30 000 objects and the message following: Len: 30000 and Number parsed: 15001 In my catalog: 15000 object only were destroyed. !!! Phase B: I de-comment my comment lines, but I've got the same message. I try to understand what it happens, but I can't. Anyone has a brillant idea?

https with zope 2.7
by Thomas Anderson 13 Feb '04

13 Feb '04

A fairy clean way did exist in 2.6.x to get zope to generate "https:" instead of "http" in self referencing URLs, using Pound, and without standing on one leg and shaking a rattle at apache mod_proxy / rewrite. http://mail.zope.org/pipermail/zope/2004-February/thread.html#146614 The magic in z2.py happened by adding a new HTTPS server with: + try: + del HTTPS_ENV['HTTP'] + except KeyError: + pass + HTTPS_ENV['HTTPS']='ON' I'm not seeing an easy way to achieve the same in Zope 2.7, or perhaps I'm just not as familiar with the code yet. Could someone point me in the right direction?? Tom
