[Zope] [ANN] Zope 2.8.1 final released

[Andreas Jung]

Hi all,

on behalf of Zope Corporation and the Zope community I am pleased to 
announce the release of Zope 2.8.1.  You can download Zope 2.8.1 from


 http://www.zope.org/Products/Zope/2.8.1/

Some new features of Zope 2.8:

  - ZODB 3.4 with MVCC (multi version concurrency control) support.
MVCC solves nearly every problem with ZODB read-conflict errors
which is very important for high-traffic Zope sites.

  - Extension Classes were rewritten as Python new-style classes making
all features of Python new-style classes available in Zope
objects. This includes support for cyclic garbage collection.

  - Integration of Zope 3 technologies through Five (see 
http://codespeak.net/z3/five/)



For more information on what is new in this release, see the
CHANGES.txt files for the release:

 http://www.zope.org/Products/Zope/2.8.1/CHANGES.txt

See also:

 http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView

Please bring all the bugs you have found to the Zope bugtracker:

  http://collector.zope.org/Zope":http://collector.zope.org/Zope

For more information on the available Zope releases, guidance for selecting
the right distribution and installation instructions, please see:

  http://www.plope.com/Books/2_7Edition/InstallingZope.stx

Please also keep in mind that Zope 2.8.1 requires Python 2.3.5. Zope 2.8.1
is not certified for any Python 2.4.x versions. So using Python 2.4 is 
neither recommended nor supported and any related questions or problems are 
likely to be ignored until 2.4 is an officially support Python version for 
Zope.

Re: [Zope] How to set an object's last modification time

Correct, you should not be.  All _p_ attributes are reserved
for use by the ZODB and applications should never mess with them.

But I need to track the modification time of *all* objects (folders, zpt, 
python scripts, instances of third-party installed products...).
I go back and forth from FileStorage to a filesystem representation (using 
APE) which is under CVS control.


Fortunately I've found a way to successfully modify _p_serial: just ignore 
the (fictitious) conflict. In fact, there is no real conflict since no data 
has been modified (and no other thread is running), just the timestamp was 
changed.


def ignoreConflict(self, oid, committedSerial, oldSerial, newpickle,
 committedData=''):
self._serial = oldSerial
return newpickle
from ZODB.FileStorage import FileStorage
FileStorage.tryToResolveConflict = ignoreConflict

Of course this script is run offline, with a single user accessing the 
database, and it works for this specific situation because I know there is 
no real conflict.

Re: [Zope] ZODB BTrees File Storage error on start up

[David Pratt]

Hi Dieter. It is rather strange for sure.  The warning has appeared 
over the past couple of days. First day I removed what I thought might 
be a bad CMFBTree folder since it was last thing I remember working 
with from previous night to do with BTrees.  Then it appeared again - 
first restart of the day - it never appeared again that day even after 
a number of restarts. Received the error again this morning - first 
restart of day.  This time cleared the Data.fs.index and restarted. 
Again it did not appear again all day after a number of restarts. It 
almost makes me wonder if it is somehow related to automated backup 
since it appears consistently on the first restart of the day. Can this 
make any sense? Like the index is getting corrupted from backup.


The only other thing that I can think of at the moment is that I had 
some nested CMFBTreeFolders that were not registered properly 
registered in the types tool yet inside a CMFSite instance. These were 
added programmatically with manage_add. I don't know if this could 
result in this error.  In any case, I am resolving the types tool 
registration issue tonight and will see what happens tomorrow am.


I am restarting this zope several times a day since I am developing on 
it. I have been adding and removing many BTree folders since I am in 
process of building a product that will use these quite a bit. I have 
been running tests then removing CMFBTreeFolders, updating product, 
restarting, rerunning with changes, etc


In any case I will examine fsBtree as you have suggested if I see 
warning again tomorrow in my log. This is a relatively new CMF1.5.2 and 
Zope2.8.0 instance and the only server I have this combination on at 
the moment.


Regards,
David

Mysterious:

"BTrees._fsBTree.fsBTree" should have a '__basicnew__'

Try to import "fsBTree" in an interactive Python interpreter
and check it.

Re: [Zope] BTree Folders questions

[David Pratt]

Hi Jens.  Thank you for your advice.  I am planning on contents of 
folders to be no more than 2000 items maximum and using CMFBTreeFolders 
for larger folders consistent with your recommendations.


I am using CMF 1.5.2 and Zope 2.8.0  - will upgrading again this week 
to 1.5.3 and 2.8.1  I removed my BTreeFolder2 product as it was 
indicating it was duplicated product in my event log after my recent 
upgrade - so it appears to have become part of the distribution.


I did not really understand the difference between a BTreeFolder2 and a 
CMFBTreeFolder since CMFBTreeFolder did not appear as content even 
though it is displayed as an option in Core Content  in ZMI.   So my 
content was appearing on the web but not visible in the portal as a 
folder. I guess I am wondering why isn't it ready to go by default as a 
core type in CMFDefault. It appears everything is there except 
registering in types tool.  My opinion is it would be really great if 
it were included as a core type (in the sense it is ready to go as the 
other types are). It could also remove confusion in ZMI that Core 
Content will produce content that is immediately recognized by the 
portal.  Many thanks.


Regards,
David

Do you have the BTreeFolder2 product installed? Only then can you

You miss that you must provide complete problem reports:

  What does "unable to set 'Title' attribute" mean?

  What is the 'Title' attribute?

  What happens when you try (exception? then we need the traceback!)
>When adding a document the 'ID' also shows up in the 'Title' section,

What is the "'Title' section"? Do you mean the HTML "title" element?

In fact, this looks like a broken pickle in your ZODB storage (and
not like a ZCatalog problem).

To do what?

There is a "Database Manager" in the "Control_Panel" -- but
(of course), the ZODB is very easy to manage.
That's why the "Manager" is so simple...

This typically is indicative of a user pressing their stop button on a

There is probably a (real) RDB connection per Zope thread times the

[Zope] BTree Folders questions

[David Pratt]

How many objects should one have in a single folder to consider using 
BTree Folder over the regular Folder?  Does it make sense to use a 
BTree folder for 100 - 500 objects or should it be reserved for 
situations where there are say 1000 + objects or more. Are there any 
benefits to be gained at the lower end as well or are there drawbacks?


On another note, why do CMFBTree folders not appear in CMF? Is this the 
way they are supposed to work?  If so, what differentiates them from a 
BTreeFolder2 if they are not a type visible to CMF?  Many thanks.

Well, you /can't/ tell IIS not to listen on that "domain" - it listens
at a port on an IP. The host header translation for virtual hosting can
only happen if it can field the request in the first place (e.g. if
there are no clashes at that port/IP). If you have a single interface,
you are stuck using non-standard ports to avoid clashes. Apache will not
bind to port 80 either because you have http://mail.sbcscot.com bound to
the same port & IP, or because of the "socket pooling" nonsense if you
have a separate IP.

I would not touch ISA with a barge-pole if I had a choice - but assuming
you are on SBS and are/could be behind a separate firewall, I would: -

- Leave Zope/Plone on 8080

- Change the port for webmail (and any other IIS stuff) to a different
high port (e.g. 9080?), so it is no longer clashing with Apache.

- Disable "socket pooling". 

- Run Apache on port 80

- Use virtual hosts with rewrite rules in the Apache .conf to pass
requests to your Zope and Webmail sites.

You could probably do something similar with ISA server (I do, but not
on the same box as IIS and Zope/Plone), but I'd rather not even think
about that...

[Zope] Zope service being shut down automatically on Windows

[michael nt milne]

Does anyone have experience of their Zope/Plone instance being closed
down mysteriously on windows XP or other windows platforms. A microsoft
demon? I keep having to re-start it.

Re: [Zope] Re: localhost:8080 not found on windows

[michael nt milne]

Hi

I've even tried using the machine's local IP but that doesn't work in
the same way that localhost doesn't. I've installed Apache now as well
so as to route requests through that to Zope.

I'm going to be using the same IP address that the webmail exchange
service uses. It uses mail.sbcscot.com so I guess if I have
http://plone.sbcscot.com then I could tell Apache to route that to
Zope? How would I tell IIS or ISA not to listen to that domain?
Meanwhile I noticed on installing Apache that it failed to bind to port

Re: [Zope] Changing Properties With ZPT

[Dyyryath]

Thanks for the reply, Andreas.

Actually, I probably didn't properly explain my question. I do realize
that the template is an object and that all I need to do is access the
template's API to modify it's properties (though, I admit I'm a newbie
here). 

My problem is that the only way I can find to access the template object
is through ZPT's built-in variable 'template'. Since I'd like to change
the property, it seems like I'll need to use a python line that uses the
template's manage_changeProperties() method. I'm just not sure what the
python equivalent of the ZPT 'template' variable is.

An example is probably in order. Take the following code:

TITLE HERE
TITLE HERE

The first line does what I'd like it to do, it returns the 'title'
property of the template.

The second line doesn't. It returns the 'title' property of the
template's container.

How do I make the second line do the same thing as the first line. If
someone can give me that, I'll know how to do the rest.

Re: [Zope] fsrecover.py won't pack

[Andy Altepeter]

Hi Tim,

Thank you for your response.  fsrefs.py raised the same error I reported 
earlier about unpickling.  I ended up:
1) Creating a new instance_home using zope-2.5.0-final
2) using zopectl debug connected to the bad database, I exported all my 
objects.  For folders that couldn't be exported, I started 'drilling down' 
until I found the object that was causing problems.  There were about 5 such 
objects in my database.
 - Some objects (folderish) could be exported, but then would raise a POSKey 
error upon import, so I drilled down in those folders as well.
3) I imported each .zexp into the new database.

This process was time consuming, but it appears to have recreated the ZODB in 
a sane state.  I think it's time to look into using repozo for backups ;-)

Andy

I despise ISA Server with a passion - have just spent a couple of hours
hunting down a silly mistake in one of my rules in the 2K3 version which
would have stuck out like a sore thumb in an Apache .conf file.

I wouldn't make any assumptions about what it might block, up to and
including localhost - it bites me time after time, and all I ever have
to do is add web publishing rules, which that /should/ be simple enough.
Problem is, it's all hidden in tabbed dialogues where you can't see the
whole rule at once...

[Zope] Re: howto i18n?

[Josef Meile]

Hi Vlada,


for now I use the Zope 2.7.5 tarball. I write freelance (not bound in a
product) page template and wish it to be i18n'ed. I have appropriate
tags inside and the domain set at the top. There is also Plone with its
products in that instance.

Where should I put the PO files, so the messages can be substituted?

Normally you have to put them inside a i18n folder located in your
product tree. However, according to your message, you don't have a
python product, so, I guess, you have to look for the plone's i18n
folder and put your PO files there. The only problem I see here is that
you have to remmember it every time you update plone.

I'm not sure if this would work: you could try to create a dummy folder,
let's say MyTranslations, inside the Products folder of your instance.
Then create an empty __init__.py file and add a 18n folder to put your
PO files.

Regards,
Josef

What means "streaming" for you? REQUEST.RESPONSE.write(data) write the

look at the filestream_iterator implementation in Zope 2.7.X

Thanks for the help here. I'm calling in a support engineer to try and

though that localhost doesn't work. Because that wouldn't go through

I've also noticed that something shuts down pythonservice.exe program
