[Zope-dev] RestrictedPython - inserting variables before doing exec(code)
Good day! Refs: http://pypi.python.org/pypi/RestrictedPython I want to pass existing bound variables into the environment of some restricted code before running it. This is similar to when globals are passed to compile_restricted_function. The idea... x = 42 y = 'foo' src=print x*2; print y; return printed code=compile_restricted(src, 'string', 'exec') code.global['x'] = x # - just dreaming, here. code.global['y'] = y # - just dreaming, here. ans = exec(code) in restricted_globals print ans# prints 84\n'foo'\n It's clear that passing in arbitrary objects is not feasible. But what if I'm prepared to constrain input to built-in numeric and string types, possibly in or with nested dicts? In many cases the input will be large integer or float arrays, and I want to avoid any nasty kludge such as printing those inputs into the top lines of the src ;). The src in the demo is a constant, but in the application, it's provided by users via a list of pre-defined and user-created 'macros'. If I'm missing something obvious, flames welcome! --r.

Please notify the servers administrator and/or owner about this. You shouldn't be allowed near a root prompt. At least till you've done your homework to the extend that you pay attention before doing anything as root. Besides, nobody told you to do this as root. When giving commands as root, you can destroy everything that is on that server. For starters try it with `rm -rf /`. Why don't you try the installation first on a test machine or personal workstation? We all have to learn stuff first, but a production server isn't a learning environment. Nowadays it is *very* easy to get a Unix clone system to play around with. There is also documentation to be found about Zope and System Administration in general, for free on the Internet.

So do you think I should throw in the towel now? If you only have one server available and if it is a production server, then you need to think about the ramifications of crashing that server. 'Production server' means different things to different organizations, and if no-one is going to be screaming at you if you kill the server then carry on! However, if your organization takes a dim view of production server downtime, then I would caution you against proceeding! You don't need to be a linux expert to install zope, but you do need at least a rudimentary understanding of how linux works and how some basic commands work. I would recommend spending some time reading the intro chapters of some linux documentation (you can find some at http://www.linux.org/docs/, and there is a good doc at: http://www.centos.org/docs/4/html/rhel-rg-en-4/) - it may seem like a waste of time, but it will save you time and aggravation in the future. If you do not want to spend the time on linux/zope and you just want to 'get working', you could look at some of the zope hosting companies (they already have zope up and running, and they look after maintaining the 'infrastructure', which lets you focus on your application).

Hi Jake,
Firstly I'll just mention a little bit more about the server. We have
cPanel and Apache running. There's a number of accounts setup in cPanel and
I've tried to access Zope via one of these urls (www.domain.tld:8080) but to
no avail. I've also tried the IP of the server with no luck. I don't know
what else to try now, as I mentioned before I'm completely new to all of
this stuff so it's quite a steep learning curve. I also don't know what you
mean by use top :S
Thanks for your reply BTW.

My python 2.4.2 is installed in /usr/local/bin and this directory is contained with the PATH environment variable (type echo $PATH at the command prompt - if the directory containing your python 2.x is not in PATH you will need to modify PATH) 5) at the command line enter: ./configure 6) at the command line enter: make 7) at the command line enter: make install(This will install zope in /usr/local/zope-2.9.x) Now you need to add a 'zope' user to your system (if you do not already have one) 8) cd /etc 9) groupadd zope (unless you already have a zope group defined) 10) useradd -g zope zope (this creates a zope user) 11) passwd zope (sets a password for the new user) 12) usermod -d /apps/zope zope (sets the home directory for the new user to /apps/zope) Now you need to create a zope instance: 13) change directory to /usr/local/zope-2.9.x/bin 14) su zope (change to the zope user you created earlier) 15) at the command line enter: /usr/local/bin/python mkzopeinstance.py (note: replace /usr/local/bin/python with the location of your python 2.4.x installation) You will be prompted for a zope instance home (i use /apps/zope), a username and a password (your zope admin account) 16) change directory to the new zope instance home (eg. cd /apps/zope) and you should see several subdirectories. 17) check the ownership of the directories/files - they should all be owned by zope and belong to the zope group. To change them enter: chown zope * (changes ownership); chgrp zope * (changes group) Now you need to make a couple of small changes to the zope.conf file: 18) cd /apps/zope/etc 19) edit the zope.conf file (save a copy first!) and change debug-mode to 'on' (optional) and change effective-user to 'zope' Now you need to start the zope instance: 20) cd /apps/zope/bin 21) ./zopectl start (or ./zopectl fg in case of errors during start up) HTH!

Re: [Zope-dev] Referencial Integrity in ZCatalogs
Take a look at archetypes on Plone.org, and download a version from sf.net. Look in particular at the ReferenceEngine, based on the catalog, and note that there have been implementation changes, and there's a new beta version.

At this point, I can see a lot of advantatges of use ZODB with Zope, but there are some points where the relational model was more useful to me. In fact, the main problem in my applications are relationships. In a relational world, you can specify relations using foreign keys, and also say what action should be done on delete or on update (no action, set null, restrict, cascade, set default). This is very useful developing business oriented applications. Using ZODB some of these relations can be done using containment: If A contains B, this is the same of having a relation 1->N on delete cascade Another case is to use a Relation Manager. I've implemented and object Relation that is deleted when some of the two related objects are (using manage_beforeDelete). This is the same that a relation M -> N on delete cascade The third case I've been implemented, and the one giving me more problems, is to have a property referencing another object (path or UID). If the referenced object is dropped, the referer has problems I work a lot with ZCatalogs, using one catalog for each meta_type of objects, so for me catalogs are the most similar thing to a Table. I'm thinking that could be very useful to implement some basic referencial integrity in ZCatalogs. Just being able to define primary keys and some simple types of foreign keys we will have on Zope the best of two worlds. Seeing code of ZCatalog product it seems not to be very difficult to implement, adding some validations on catalog_object and uncatalog_object methods. Of course, all these should be optional. I no Primary Keys neither Foreign Keys are defined, catalogs should work exactly like until now. What do you think about this ? If nobody convince me that this is a stupid work, I will try to implement it. In this case, what's the better way to provide the code ? A patch for ZCatalog ?

[Zope-dev] KeyError in GlobalTranslationService.py
I just submitted a patch for Plone 2.0.3
http://plone.org/collector/3329
that stops a KeyError from being triggered in GlobalTranslationService.py when a msgid contains a $
I think that passing a translation key containing $ should not cause an Error page.
So here's a patch for Zope that at least prevents the problem. Translation Service dudes will probably pick big holes in it.

Re: [Zope-dev] ERROR(200) ZODB Couldn't load state for... Memory problem?
This thread's not over 'til the fat lady sings.
OK, so apologies first:
Paul Winkler's comment in this thread was nearer the mark than Tres Seavers. clienthome is not relevant to where caches are created, and of course I need zeo-client-home.
Problem is now that zeo-client-home seems not to have the intended effect.
I set zeo-client-home to zeo1, in my first conf file and restart, but never see any cache files of that name.
I traced as far as the parse handler zeo_client_home. It's invoked with the correct value. But it stuffs the value into the env, and I can't see any other reference to ZEO_CLIENT pulling it back out of there again.
Working up the stack trace from ClientCache.py, where the files are created (*-None-*), my client value is always None, but there's a gap in the middle that I did not bridge, around BaseConfig and ZeoConfig.
Has anyone been successful naming cache files? I'm on OSX Panther 10.3.

Fair enough. I'm setting a name. Here are my other critical items:

mount-point /temp_folder

So I cd to the zope root and..
grep -r zeo-client-name *
lib/python/Zope/Startup/zopeschema.xml: key name=zeo-client-name handler=zeo_client_name>
So zeo-client-name is handled by zeo_client_name. Great! I shoved a pdb_trace there. n and l give me
76 def zeo_client_name(value):
77 value and _setenv('ZEO_CLIENT', value)
78 import pdb; pdb.set_trace()
79 -> return value
(Pdb) value
'zeo1'
Cool! So far so good.
But this brings me to the gap.. How is ZEO_CLIENT in the environment going to get into self.config.client in the ZEOClient? Bearing in mind grep -r ZEO_CLIENT * shows me only comments, apart from the handler, where it is set.
Any ideas? Anyone seen anything but *-None-* for cache files?
Meanwhile, I'm going to see why zope gets creative about spreading the cache files around.

Re: [Zope-dev] ERROR(200) ZODB Couldn't load state for... Memory problem?
Thanks Tim and Chris! - You were both dead on in so many respects. Chris, There was a correlation with flip in the logs Tim: looks like once a None occurs it sticks. Source of the problem was an old cache file (1-None-1) that could not be overwritten by the current uid running Zope. (That's the second stupid permissions problem in as many days. My advice - if you have any kind of cache problems occurring after an initial period, look hard at permissions. Secondly - don't be sloppy and run zope first as one user then as another. Thirdly grep the event logs for IOError first. That's the easiest thing to fix.) more comments below... On 23 Jul 2004, at 02:14, Tim Peters wrote: [Chris McDonough] ... I think the problem is related to ZEO client storage cache flips. .. anyway, pointing to None. But this code gives me a headache, and I'm not sure that can actually happen (despite that I hear you guys saying it is wink>). I was slow interpreting all of this due to separate event files. This piece of bash script was helpful to get a grip of time order between Clients: grep ZEC ev*.log | sed 's/:/ /' | sort -k 2 > interleaved.ZEC.events.log a multi-line merge script would be helpful. I'll bet someone's created one. But then I turned off persistent ZEO client cachefile storage (but omitting the zeo-client-name parameter from zope.conf), believing this would be a workaround, but it hasn't been. I gave up at that point and that's where I am now. Did you continue to get errors in the log near cache-flip times? I don't see a way for checkSize() to screw up unless an unexpected exception is raised. Bingo! 2004-07-21T11:35:07 INFO(0) ZEC:1-None-1 flipping cache files. new current = 1 -- 2004-07-21T11:35:07 ERROR(200) ZODB Couldn't load state for 00012323 Traceback (most recent call last): File /usr/local/zope/zope271/lib/python/ZODB/Connection.py, line 559, in setstate p, serial = self._storage.load(oid, self._version) File /usr/local/zope/zope271/lib/python/ZEO/ClientStorage.py, line 754, in load self._cache.checkSize(0) File /usr/local/zope/zope271/lib/python/ZEO/ClientCache.py, line 581, in checkSize self._f[current] = open(self._p[current],'w+b') IOError: [Errno 13] Permission denied: '1-None-1' ... My theory is that it will happen as often as a Zope client's ZEO client storage needs to flip its cache file. The cache file is only flipped when it exceeds a certain size and it only exceeds a certain size after a certain pattern of usage causes it to do so (lots of loads from the database of new items, typically). Yup! It appears that once self._f[self._current] is None, all future attempts by ZEO to store into its client cache will fail the same way. So I'd be even more surprised if you saw just one of these occur. Yup! It would be nice if you could confirm this. Reading the Zope event log file of the client that generated the error would be a good start. The log is everything here. The ZEO client cache logs most relevant messages at info level, producing msgs starting with ZEC. Thanks again for the insights. --r.

Re: [Zope-dev] Re: ERROR(200) ZODB Couldn't load state for... Memory problem?
Thanks Tres, That looks to be about it. We'll limp through today, and try this on the weekend. This will cause a couple of other changes and I don't have the nerve for it at 7PM on a Friday night. I'll let you know, and write up these last few lessons on Zope.org. --r.

No, I think Tres nailed it, in his reply. I'll confirm when I know more. Thanks anyway. --r.

Hi all, On OSX 10.3 (Pahter), Python 2.3.4, Zope 2.7.1, I'm frequently seeing this.. 2004-07-22T14:00:24 ERROR(200) ZODB Couldn't load state for 16ad Traceback (most recent call last): File /usr/local/zope/zope271/lib/python/ZODB/Connection.py, line 559, in setstate p, serial = self._storage.load(oid, self._version) File /usr/local/zope/zope271/lib/python/ZEO/ClientStorage.py, line 755, in load self._cache.store(oid, p, s, v, pv, sv) File /usr/local/zope/zope271/lib/python/ZEO/ClientCache.py, line 601, in store self._store(oid, p, s, version, pv, sv) File /usr/local/zope/zope271/lib/python/ZEO/ClientCache.py, line 631, in _store f.seek(self._pos) AttributeError: 'NoneType' object has no attribute 'seek' It's intermittent at first, then back-to-back.

Re: [Zope-dev] ERROR(200) ZODB Couldn't load state for... Memory problem?
Thanks, Chris. We're fronting two Zopes with Pound for load balancing. I can't see there would be any connection with this error. But I mention it in case there's a pattern. Also, the database came from 2.7.0 and an earlier python. This looks like resource starvation to me. The servers run for an hour or two this problems shows up, becoming worse for a while, then we need a restart. I'm try to debug it tomorrow. What would you look for? Any tips for resource monitoring? --r. On 22 Jul 2004, at 21:49, Chris McDonough wrote: I have seen this as well but I haven't been able to pin it down.
