Hi! I successfully applied these hotfixes to Zope 2.13 versions without any problems. What puzzles me though is why was there no announcement for theses fixes here on zope ml?

[Zope] changing permissions on classes/methods at runtime?
hi all!
is it possible to change permissions and roles on classes/methods
at runtime? normally you'd attach security declarations inline in
your class definition code:
from AccessControl import ClassSecurityInfo
from AccessControl.class_init import InitializeClass
class Cls():
security = ClassSecurityInfo()
security.declarePrivate('foo')
def foo(self):
pass
InitializeClass(Cls)
now what i tried at runtime is:
from mycode import Cls
from AccessControl import ClassSecurityInfo
security = ClassSecurityInfo()
security.declarePublic('foo')
security.apply(Cls)
but this does not what i want it to, in fact it doesn't seem
to do anything yet - probably because i'm using the wrong way :)
any hints how to do this correctly would be greatly appreciated.
thank you very much in advance and best regards,
Jürgen Herrmann

No. The limits aren't really limits.

As you're iterating through the objects, if you know you aren't going to need an object again or otherwise think it would be OK to free it from memory, you can call _p_deactivate on it. If the object hasn't been modified, then it's state will be released and it will become a ghost. as my objects contain references to OOBTrees, do i also have to call _p_deactivate() on these explicitly, or is it enough to call it on the containing object? thanks for your help! best regards, jürgen -- XLhost.de - eXperts in Linux hosting ® XLhost.de GmbH Jürgen Herrmann, Geschäftsführer Boelckestrasse 21, 93051 Regensburg, Germany Geschäftsführer: Volker Geith, Jürgen Herrmann Registriert unter: HRB9918 Umsatzsteuer-Identifikationsnummer: DE245931218 Fon: +49 (0)800 XLHOSTDE [0800 95467833] Fax: +49 (0)800 95467830 WEB: http://www.XLhost.de IRC: #xlh...@irc.quakenet.org ___ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )

to a new virtualenv. outcome is reported here:
You haven't read the docs carefully:
http://docs.zope.org/zope2/releases/2.12/INSTALL.html
i read it again, this time following the section Installing Zope
using easy_install word by word (except inserting the correct zope2
version number into the easy_install command).
here's the outcome:
[...@t5-laptop ~]$ virtualenv --no-site-packages my_zope

a debug print before the exception is raised revealed the following:
- a __import__('relstorage') on line 204 of ZConfig/loader.py loads the
module just fine.
- the test hasattr(pkg, __path__) on line 211 fails.
- a __import__('relstorage') in my virtualenv's python interpreter imports
the module and there it has a __path__ attribute!
in a newsgroup posting i read the following sentence:
modules don't have __path__, only packages do. wtf???
his is as much information as i can provide. i'm somehow lost and confused now.
any hints?
thanks in advance and best regards!

[Zope] zope2, buildout and relstorage
i want to use relstorage with zope 2.10 and have read about the fake egg procedure at http://pypi.python.org/pypi/plone.recipe.zope2install is there any documentation how to use that recipe? i tried downloading and unpacking from http://pypi.python.org/packages/source/p/plone.recipe.zope2install/ but i'm, a bit lost there. from the readme i read that i should run python2.4 bootstrap.py first, and then? obviously the shipped buildout.cfg puts a zope2 source tree in parts/zope2 after running bin/buildout. the eggs dir contains: plone.recipe.zope~all-3.0-py2.4.egg setuptools-0.6c9-py2.4.egg zc.buildout-1.2.1-py2.4.egg and fake-eggs has: Acquisition/ zope.app.renderer/ ClientForm/zope.app.rotterdam/ DateTime/ zope.app.schema/ docutils/ zope.app.security/ ExtensionClass/zope.app.servicenames/ mechanize/ zope.app.session/ Persistence/ zope.app.site/ pytz/ zope.app.size/ RestrictedPython/ zope.app.skins/ tempstorage/ zope.app.sqlscript/ ZConfig/ zope.app.testing/ zdaemon/ zope.app.tests/ zLOG/ zope.app.timezones/ ZODB3/ zope.app.traversing/ zodbcode/ zope.app.tree/ Zope2/ zope.app.undo/ zope.annotation/ zope.app.wfmc/ zope.app/ zope.app.wsgi/ zope.app.annotation/ zope.app.zapi/ zope.app.apidoc/ zope.app.zopeappgenerations/ zope.app.applicationcontrol/ zope.app.zptpage/ zope.app.appsetup/ zope.cachedescriptors/ zope.app.authentication/ zope.component/ zope.app.basicskin/zope.configuration/ zope.app.broken/ zope.contentprovider/ zope.app.cache/zope.contenttype/ zope.app.component/zope.copypastemove/ zope.app.container/zope.datetime/ zope.app.content/ zope.decorator/ zope.app.content_types/zope.deferredimport/ zope.app.copypastemove/zope.deprecation/ zope.app.datetimeutils/zope.documenttemplate/ zope.app.debug/zope.dottedname/ zope.app.decorator/zope.dublincore/ zope.app.dependable/ zope.event/ zope.app.dtmlpage/ zope.exceptions/ zope.app.dublincore/ zope.filerepresentation/ zope.app.error/zope.formlib/ zope.app.event/zope.hookable/ zope.app.exception/zope.i18n/ zope.app.file/ zope.i18nmessageid/ zope.app.filerepresentation/ zope.index/ zope.app.folder/ zope.interface/ zope.app.form/ zope.lifecycleevent/ zope.app.ftests/ zope.location/ zope.app.generations/ zope.modulealias/ zope.app.http/ zope.pagetemplate/ zope.app.i18n/ zope.proxy/ zope.app.interface/zope.publisher/ zope.app.intid/zope.rdb/ zope.app.introspector/ zope.schema/ zope.app.keyreference/ zope.security/ zope.app.layers/ zope.sendmail/ zope.app.locales/ zope.server/ zope.app.location/ zope.size/ zope.app.mail/ zope.structuredtext/ zope.app.onlinehelp/ zope.tal/ zope.app.pagetemplate/ zope.tales/ zope.app.preference/ zope.testbrowser/ zope.app.preview/ zope.testing/ zope.app.principalannotation/ zope.thread/ zope.app.publication/ zope.traversing/ zope.app.publisher/zope.viewlet/ zope.app.rdb/ zope.wfmc/ how do i move forward from here? how to use that source tree and how to install relstorage into it? thanks in advance and best regards! jürgen -- XLhost.de - eXperts in Linux hosting ® XLhost.de GmbH Jürgen Herrmann, Geschäftsführer Boelckestrasse 21, 93051 Regensburg, Germany Geschäftsführer: Volker Geith, Jürgen Herrmann Registriert unter: HRB9918 Umsatzsteuer-Identifikationsnummer: DE245931218 Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)700 XLHOSTDE [0700 95467833] WEB: http://www.XLhost.de IRC: #xlh...@irc.quakenet.org ___ 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] relstorage on zope 2.10.5
hi there!
today i thought i'ds give relstorage a try, esp. for it's
small startup times compared to filestorage.
i followed the instructions at

an when calling
python2.4 setup.py install --install-lib=${INSTANCE_HOME}/lib/python
(instance home is set of course)

the version of zopdb shipped with zope 2.10.5 is 3.7.1, so why
does the command above try to pull an alpha release of zodb?
can in pin the version of zodb to 3.7.1?
my versions used:

If you install Python using configure --prefix=/opt/python-2.4; make;make install and configure Zope using configure --with-python=/opt/python-2.4/bin/python2.4; make; make install you should never get into such trouble. Somehow your environment or setup must be broken. Possibly you're installing Zope over an existing Zope installation with possibly old zopectl/runzope files inside the 'bin' folder which won't be replaced by make install. So check the python configuration within your bin/zopectl|runzope files. Thanks again - the above is what I thought I did (matching the --prefix and the --with-python) - however somewhere I blew it somehow as the control files point to the wrong python. I'll try again and hopefully get it right. Thanks for the extra assist. Well, I'm not crazy. I just rebuilt it all and triple checked that I gave the matching --with-python when configuring the zope build. I did. And, it did not get used...the zopectl and runzope files were created with the default path (to the wrong python) anyhow! did you really delete the existing files in your bin folder before installing zope again? these files are NOT recreated! regards, jürgen So I fixed that manually, and now (after fixing some perms issues) it starts up OK. thanks again, John S. -- John Schinnerer, MA WSD -- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration [EMAIL PROTECTED] http://eco-living.net ___ 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 ) ___ XLhost.de - eXperts in Linux hosting ® XLhost.de GmbH Jürgen Herrmann, Geschäftsführer Konrad Adenauer Allee 43, 93051 Regensburg, Germany Geschäftsführer: Volker Geith, Jürgen Herrmann Registriert unter: HRB9918 Umsatzsteuer-Identifikationsnummer: DE245931218 Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)700 XLHOSTDE [0700 95467833] WEB: http://www.XLhost.de IRC: [EMAIL PROTECTED] ___ XLhost.de - eXperts in Linux hosting ® XLhost.de GmbH Jürgen Herrmann, Geschäftsführer Konrad Adenauer Allee 43, 93051 Regensburg, Germany Geschäftsführer: Volker Geith, Jürgen Herrmann Registriert unter: HRB9918 Umsatzsteuer-Identifikationsnummer: DE245931218 Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)700 XLHOSTDE [0700 95467833] WEB: http://www.XLhost.de IRC: [EMAIL PROTECTED] ___ 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] storing persisten object in python dictionaries
hi! i have a writeen am framework where objects have unique ids and instances are stored in btreefolders, one per class. if i want to retrieve an instance based on id, i lookup it's class name and the get the class' container path from my metadata manager (f.ex. /app/data/Appointments/instances). now i traverse to this container and get the object with given id from there. the process of traversing to the class' container folder is done on each object get. a cool optimization for me would be to cache class container folders in a python dictionary (much faster than traversal), but this doesn't work. the main problem is that objects retrieved from these cached folders have broken acquisition. actually i asked a similar question some time ago and was told: don't store persistent objects in python dicts. i changed my code back to traversal and everything works, but now i finally reached the optimization stage and profiling indeed shows a huge improvement in object lookup with class container caching enabled. so can anybody tell me why this doesn't work, or what to respect to make it working? btw. the cache dict is implemented as a volatile attribute (_v_classContainerDict) of a singleton object in the db. best regards, jürgen herrmann ___ XLhost.de - eXperts in Linux hosting Jürgen Herrmann Konrad Adenauer Allee 43, DE-93051 Regensburg Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)721 151 463027 WEB: http://www.XLhost.de ___ 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 )

uhm, ran some more tests, seems this works fine for the first thread but not
for the others, i get
an error when loading a framed page
for example (obviously the browser sends two concurrent requests).
the error is as follows:

Module
ZODB.Connection, line 729, in setstate
ConnectionStateError: Shouldn't load state for 0x010f98 when the connection is
closed
the above code can obvioulsy only work if there is exactly one single
connection tied to one
thread and it's not closed while the thread is alive.
anybody have suggestions on how to tackle this?

seems i can answer my quesitons for myself today :)
i figured if it's a per-connection problem - why not store the dict
at the connection... the code now reads as follows:
def _classContainer(self, className):
return the instances folder for className
conn = self._p_jar
containerDict = getattr(conn, '_relClsContainerDict', None)
if containerDict is None:
containerDict = {}
conn._relClsContainerDict = containerDict
container = containerDict.get(className, None)
if container is None:
container =
self.unrestrictedTraverse(self._classContainerPath(className))
containerDict[className] = container
return container
we'll see if this throws up other problems...

Just a guess (the python gurus could answer this for sure), but lambda
functions have access to variables in the containing scope, which in your
case is the date.sort function. Does date.sort provide access to 'context'?
A quick test would be to get rid of the lambda function and create a named
function and see if that works.
i have to add that this was a normal page template file before, just
converted i to a trusted one. in the normal page template file this
expression just worked.
i'll dig a bit deeper tomorrow if nothing comes up here.
going home now, my brain refuses to think any longer.
regards, juergen
i tried what Jonathan suggested and replaced the lambda by a named
comparison function and it works. so my advice for people who might
search the mailinglist in the future:
do not use lambdas in python expressions in trusted fs page templates.

[Zope-dev] ImageFile weirdness?
hi all!
i have a class ImageContainer in a python product, that has an ImageFile
attached, it's named 1.gif:
...
image = ImageFile('1.gif', '/some/where')
setattr(self.__class__, '1.gif', image)
...
i have an ImageContainer instance in my zope root.
if i point my browser to http://localhost/ImageContainer/1.gif ,
i can see the image in the browser, everything seems fine, image is
displayed.
if however the image is named 1 only, e.g.
...
image = ImageFile('1', '/some/where')
setattr(self.__class__, '1', image)
...
i notice a difference when viewing http://localhost/ImageContainer/1 .
the browser pops up a download window, showing the content type is
application/octet-stream. using firefox' livehttpheaders extension i found
out that the content-type header is missing. if i view
http://localhost/ImageContainer/1/ everything is fine however.
now i peeked into App.ImageFile, where i can find a index_html() method,
where the content-type header is set.
viewing http://localhost/ImageContainer/1 never calls the index_html
method though, http://localhost/ImageContainer/1/ obviously does.
that's where i'm stuck now, who handles the ImageFile's invokation, if
called like http://localhost/ImageContainer/1 ? ImageFile inherits from
Acquisition.Explicit, nothing else...
thanks for your attention,

Re: [Zope] five i18n
me again :)
some more things i found out:
1. MyLanguages is instantiated on every http request but
regardless of what i return (['DE'] or ['de']) i always get the
english translation. weird?!
2. seems that only page templates served through an http request
trigger the i18n stuff at all. if so, how can i circumvent this?
(i want to generate xml and run it through trml2pdf to produce
pdf output, which works excellent - but not with i18n)
thanks for your help.

Re: [Zope] Re: DateTime strftime problem
zope 2.7.8's DateTime::strftime() looks like this:
def strftime(self, format):
# Format the date/time using the *local timezone representation*.
return strftime(format, safelocaltime(self.timeTime()))
it seems that my assumption about strftime's behaviour was incorrect.
why do we have time zones at all, if strftime always uses the machine's
local time zone?
would this be better off in a new method, similar to strftime but
respecting the DateTime's current time zone? (that's what i need)
submitting a patch with my implementation is likely to be refused
because it changes long standing behaviour...
on the other hand, if DateTime's strftime should behave as similar
as possible to datetime's strftime, it should respect the timezone
information attached to it.
honestly i don't know what to do... i can just make this a monkeypatch
and only use it myself, but that just didn't feel like the right thing
to do :)
regards, juergen herrmann
[ Florent Guillaume wrote:]
The DateTime implementation in Zope is notoriously undertested and
underspecified when it comes to time zones. Until recently strftime was
quite buggy too, and as you saw it has been recoded in terms of the python
datetime implementation now that it exists. It's very possible that a bug
was introduced at that point, it would be useful to check with Zope 2.7's
DateTime. Or the bug has always been there.
It think it's a good thing if DateTime can behave more regularly, which
means be more in line with python's datetime, in corner cases.
Please submit a patch to the collector. It probably will be included in
2.9
but not 2.8 which is strictly in maintenance mode, unless you convince us
that it's very unlikely that code would change behavior as a result.

hmm, where's the timezone information gone? to make it short, how
can i get a text representation of a DateTime object in a given
timezone?
thanks in advance!

-aj
me once again...
d = DateTime('2005/04/03 02:01 GMT').toZone('GMT+1')
s = d.strftime('%Y/%m/%d %H:%M %Z')
here i would expect s == '2005/04/03 03:01 GMT+1',
do i have the correct expectation here?
what is d.strftime('%Y/%m/%d %H:%M') expected to return then?

either this is a bug or i'm too stoned to see, what's going on...
i have a folder /1, 2 subfolders /1/11 and /1/22. each subfolder
has a property 'bool', which is a boolean.
there's a zcatalog instance in /1/Catalog with one index bool, indexed
attribute 'bool'. i cataloged the two subfolders of /1 there.
i have i skript /1/test with the following content:
results = context.Catalog.searchResults({'bool':1})
print results
for o in results:
print o
print o.getId
print o.getId()
return printed
it prints:

i was dumb :)
the metadata table simply didn't have getId, so the brains object
acquires getId from the catalog.
sorry for my nubness ;P

Easy. The brain object doesn't have a 'getId()' method. The Catalog has.
What you're probably after is something like this::
for brain in context.Catalog.searchResults({'bool':1}):
cataloged_object = brain.getObject()
if cataloged_object is None:
print ZCatalog out of sync!!
else:
print cataloged_object.getId()

[Zope] python question
hi all! i think there should be no functional difference in the two code snippets below, but is there any difference in performance? (i know, the except AttributeError could possibly mask an AttributeError in the called function...) 1.: hook = getattr(o, '_before_transaction_commit', None) if hook: hook() 2.: try: o._before_transaction_commit() except AttributeError: pass regards, juergen herrmann ___ XLhost.de - eXperts in Linux hosting Juergen Herrmann Weiherweg 10, 93051 Regensburg, Germany Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)721 151 463027 ICQ: 27139974 - IRC: [EMAIL PROTECTED] WEB: http://www.XLhost.de ___ 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] automagic reindexing of objects
hi all!
as i had time to look at all the stuff, i realized, that i'm
getting closer, but this is not exactly what i wanted...
as i can see from the path, one has to call:
beforeCommitHook(method, **args, **kwargs)
on each transaction, correct?
this is contrary to my idea of everything doing it's work automagically.
what i want is a kind of callback to each dirty object, something like
this:
class Transaction(...):
def commit(self, ...):
# insert this:
for object in self._objects:
try:
object._before_transaction_commit()
except AttributeError:
pass
# rest of original commit() follows...
could this impose any unforseen behaviour?
btw: what version of the two following is better (i.e. faster and more
elegeant, i do python coding since abt. 6months only...)
try:
object._before_transaction_commit()
except AttributeError:
pass
or
hook = object.get('_before_transaction_commit', None)
if hook: hook()
another question: is it hook() or hook(object) in the previous line?
i never know if the self parameter has to be passed in if not called
as self.method() - are there any (simple) rules?

It is impossible with ZODB 3.2 (unless you patch
ZODB.Transaction.Transaction).
The CPSCompat module of CPS has monkey-patches that backport this from
ZODB 3.4, among others, to be used in Zope 2.7.

ZODB 3.4 (which is used for Zope 2.8/3.1) has hooks
that makes it possible.

You can't index before committing. I think you need a different strategy: how about creating all of the new objects and then call the catalog/indexing mechanism. We do this for one of our large volume catalogs (1m+ records), by having an object class/catalog that are not 'aware' and then manually (well, thru a python routine) cataloging/indexing the objects. hmm, it's not about newly created objects. i want to have automatic REindexing, in cleartext - i want to make it easy for the programmer: he/she should just call an attribute setter or maybe change a relation and just before the transaction would be committed to the storage, i'd like to cycle through all dirty objects and reindex them, if they're catalogpathaware (or implement reindex_object()...).

Re: [Zope] automagic reindexing of objects
[ Peter Bengtsson wrote:]
Personally I think one should stay the hell away from transactions.
They're not for you to fiddle with.
I understand your question and even though I think it's a bit crazy I
can see a benefit (simplicity for the programmer).
How about a trickery solution like this:
class CatalogPathAware:
def index_object(self, *a, **k):
print self.__class__.__name__, in for indexing!
class _MyProduct(CatalogPathAware):
def __init__(self, id, title=''):
self.id = id
self.title = title
def setTitle(self, title):
# could be much more complicated
self.title = title
class MyProduct(_MyProduct):
def setTitle(self, title):
_MyProduct.setTitle(self, title)
self.index_object()
inst = MyProduct(instanceA)
inst.setTitle('Peter')
print inst.title
You would basically rename your existing class from Whatever to
_Whatever and continue as before. This does mean however that you
have to explicitly write a function for each setter.
hmm, i can't see how this would help. if i call index_object in every
attribute getter method, the indexing is done possibly several times,
unnecessary and (cpu)time consuming.

[Zope] utf-8 vs. unicode question(s)
hi out there!
there's been some discussion about utf-8 vs. unicode strings on the
list lately. i'd like to ask if my gained understandings are correct
und thus possibly make it clear to others also.
i have set my python default encoding to utf-8, i always send http
responses from zope as utf-8 (by setting the header like this:
tal:define=dummy python:request.RESPONSE.\
setHeader('Content-Type','text/html;; charset=utf-8')
)
so if i'd like to use unicode strings in my zope applications, it's
still necessary to convert request variables to unicode by using
unicode(REQUEST.foo, 'utf-8'), right?
as far as i understodd, the conversion back to utf-8 is handled
automagically by zope (if the abovementioned header is set), also
correct?
thanks in advance for your answers!
regards, juergen herrmann

Lerner wrote:] I've written a Zope application that needs to be behind SSL. I assumed that the most straightforward way to do this would be to (1) set up Zope on port 8080 and (2) use Apache to act as a proxy between the outside world and Zope. Unfortunately, while it was a piece of cake to set up a proxy for non-SSL access to Zope, I'm rather stumped regarding SSL. I've done non-SSL proxying for years with mod_rewrite, and it was really a snap, so I'm surprised that this is so difficult. Zope is working just fine when I access it directly (using HTTP) on port 8080. I have installed the (self-signed) SSL certificate into Apache without any trouble, and am able to access individual documents on disk via SSL, using Apache. So if all I would want is to use Apache with SSL, I would be done by now. Here is the relevant portion of the Apache configuration file (with names and numbers changed somewhat): VirtualHost 66.123.23.17:443 ServerName myserver.com ServerAdmin [EMAIL PROTECTED] SSLProxyEngine on RewriteEngine On RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/https/myserver.com:443/app/$1 [L,P] /VirtualHost The above should make it possible (I believe), an HTTPS connection between my browser and my cup. Apache should then take that incoming SSL request and issue its own request to the Zope server. Zope will respond, sending it back to Apache, which (in turn) sends it back to me. But of course, that doesn't happen. Zope's provides indicates that many of the requests begin with \x80g\x01\x03. My guess is that the SSL request is being piped to Zope directly, but it's hard to know from just a few characters. Does this mean that I need to do some more translating, from HTTP into HTTPS? Not that it should make any difference, but I'm running Apache 2.0.52 on Red Hat Enterprise 4.0, with Zope 2.7.5 and Python 2.3.4.
