[Zope] Strange Catalog problem.
Hello, I'm using a modified (french, adding programatically and new classes but the ground features are untouched) Yihaw on 2.2.4 (linux). I've got a strange behaviours (YihawNews boxes don't show the new items) until i found that "old" (before upgrading to 2.2.2 + 2.2.4 update) items on the catalog don't start with "/" and the new ones does start with "/". Reindexing gives me the same 2 categories and change nothing. I'm puzzled with : * what is the "correct behaviour / or no / ? * why reindexing doesn't homogenize the / ? The "new" items are now added programatically and the "old" ones where done thru Zope interface. And sometimes i still get a "problem uncataloging before catalogging" message on the Zope console. Am i missing some important change ?

Hi,
trying the example

from the DTML-Documentation, page 3, leads to the following result
when viewing the page. Why? I am using Zope 2.2.4. I get the same
results on W98/WNT and Linux. Without this tag, the page works.

Re: [Zope] Cut/copy/paste problems
Hi! i knew that! :) btw, there's currently sparse document on mod_pcgi2. i'd like to change that, but i need info from you (the author ..straight from the horses mouth - so to speak) or snippets from your httpd.conf. do i need to have Zope.cgi available? i think i do since otherwise, there'll be no connection. or am i missing something? You missed pcgi-wrapper :) If you look into Zope.cgi (it is just plain text file) you'd found it is a script interpreted by pcgi-wrapper. That very pcgi-wrapper is a binary file compiled from pcgi-wrapper.c during the Zope installation process. The pcgi-wrapper binary is the program that implements PCGI protocol. When I wrote mod_pcgi2, I borrowed a lot of code from pcgi-wrapper.c. That way you do not need Zope.cgi or pcgi-wrapper - the PCGI code is already in mod_pcgi2. how can i finetune the performance? it seems that under heavy load, eg 100 simultaneous apache connection, it'd get loger to contact the server. in the browser, we'd see contacting the server, waiting for reply .. for about 3-4 secs before we get any activity/reply from server. You'd need to finetune Zope, not the mod_pcgi2 module. When you connect to Zope-behind-Apache the process is going the following path: 1) browser sends a rquest to Apache 2) Apache invokes the mod_pcgi2 handler 3) the handler passes the request to Zope 4) !!! here is the problem to finetune !!! If Zope's own pull requests handlers is empty - Zope does not handle the request, but queues the request and waits 5) after Zope processes the request it passes the results back 6) mod_pcgi2 passes the results to Apache 7) Apache passess it back to browser. Ususally there are 4 threads in Zope, and 7 ZODB connections. The first number - 4 threads - could be configured by passing parameter to z2.py. If you raise the number much, you'd need to raise he seconf number somwhere in the ZODB source code. These are points for finetuning. Actually you may need to tune more things, but these things are just totally unrelated to mod_pcgi2. Tune ZODB cache, install and learn to use cacheing Products (the are a number of caches for Zope), use squid, etc. when i do a packet dump, it seems that the machine needs a couple of SYN before getting and ACK from the server. do you think it has anything to do with mod_pcgi2? sorry if it's not. I'm pretty sure it has nothing with mod_pcgi2. SYN/ACK are properties of TCP/IP protocols, and PCGI protocol is much higher level. Oleg.

What is the relation to objects? 2) What do I add to a Rack and what to a Specialist to get a) a property b) a propertysheet c) an object 3) How do I switch from one implementation to another (for example from persistent storage to non-persistent storage) and what parts do I have to update 4) if I add a SkinScript, what does it really do? How does it relate to my Rack, and how to the Specialist?

No problem... I'd like to keep it on the mail list, so other folks can get
the benefit.
Chris,
I found the following in the mailing lists, it was one of your replies to
a
persistence question, I think it could finally clarify some things for me.
Now if I understand what you have been saying in the following and before
then
if I used self.a[0] = b then this will only be committed if I had called
the
function that calls this within my product. If I called the function
outside
of this, say using a dtmlMethod or an external method, then it would not
persist and instead I should really use
tmp = self.a
tmp[0] = b
self.a = tmp
The main question to ask yourself when trying to persist things is "is the
__setattr__ of a persistent object getting called"? In the above example,
the answer is yes.
I feel I am missing something. The boringplus product I made uses
self.a[0] =
b type referencing, but on a dictionary, and works well. Where would my
product fail?
It would not show your mutations of the 'self.a' dictionary:
- after the server is stopped and restarted
-or-
- after the object referenced by 'self' was flushed from the RAM
cache during normal operations
thanks for your help
regards
Matt

Chimezie is right... one clarification: you don't
necessarily
need to
make the counter an attribute of the object the

implemented on, but it needs to be an attribute of some
object
that
sublclasses Persistence.Persistent (any standard Zope
object).
Note also that you will undoubtedly be bitten at some
point
during the
writing of code in Zope by the somewhat unobvious fact
that you
need to
treat mutable Python objects that are attributes of
persistent
objects
as immutable. So instead of (for example):
self.a[0] = b
You'd need to do something like:
tmp = self.a
tmp[0] = b
self.a = tmp
Doing this triggers the persistence machinery. A
different,
short-hand
way to do this is:
self.a[0] = b
self.a._p_changed=1

Re: [Zope] persistence and dictionaries
Thanks for the reply, that is really useful. There are a couple of things
though that still don't add up. Firstly, you say below, as do all the
ZODB
documents that "Custom" classes can certainly persist, they just need to
mix in
the "Persistence.Persistent" class as a base class. Well, in my example I
attached in my first email, my product certainly has
Persistence.Persistent,
but my second class that I add to this one does not, yet it still
persists.
There was an email sometime ago on the mailing list that told someone that
this
was why their product instances disappearing from the ZODB.
(the ref for the original email is :
http://www.egroups.com/message/zope/44263
... I can't find the reply again.)
You can put instances which do not inherit from Persistence.Persistent in
your database. They just won't "stick". They'll hang around until the
server is restarted or for an undetermined amount of time during normal
operations.
So my current understanding would be that any classes you want to add in
do not
need to derive from Persistence.Persistent, and if it is pickleable then
all
should be fine if you call on instances of that object within you product.
No. It'll work for "a while" or until the server is restarted. :-)
The next part that worried me came from the "python product tutorial"
http://www.zope.org/Members/hathawsh/PythonProductTutorial
This stated that the class dictionary self.votes = {} needed to be changed
to
self._votes = Globals.PersistentMapping() so that updates to it persist.
Hence my query about dictionaries.
This was for convenience, I'd imagine.
I also noticed your comment about __setstate__ . What is it about this
that is
dangerous.
Nothing implicitly dangerous, but it can get confusing if you have multiple
revisions of your product and you use variables caused by __setstate__.
Also, once you add a __setstate__ which modifies the object in-place,
there's a likelihood that it can never go away (you're can never be sure if
all instances have been updated).
Recently I built a product out of some python classes I wrapped
around 4DOM, and since 4DOM documents do not seem to persist(well the
document
does, but it loses all its children), then I persisted them to the local
file
system, since I needed to do that anyway for what I was doing. Setstate
seemed
to work nicely to bring them back, though watching its behaviour I noticed
that
it was called very often by zope.
Sure, that works... although at that point you're creating your own object
database. :-)
Chris McDonough wrote:
All pickleable Python primitive types (strings, dictionaries, lists,
Nones,
integers, floats, longs, etc.) can live in the ZODB. They can persist
just
like instances that inherit from the Persistent class.
I think you read a little too much in to the fact that you need to
"treat
mutable objects immutably" when working with them in the ZODB. This
statement doesn't mean that these kinds of objects can't be saved in the
ZODB, it just means you need to treat them specially when putting them
in
the database.
For instance, if you were doing this inside of an external method:
def amethod(self):
self.mydict = {}
self.mydict['a'] = 1
(where self is the persistent object that is usually the external
method's
"container")
It wouldn't work as you expected. Although you'd see an 'a' in mydict
for a
little while in further accesses to it, 'mydict' would eventaully show
up as
an empty dictionary on the first access of it after it was expired from
the
RAM cache (after it was 'ghosted'), because the last thing that the ZODB
"saw" (via the __setattr__ on 'self' and a subsequent transaction) was
you
setting a empty dictionary.
Persistent objects (like "self" in the above example) are only smart
enough
to notice changes to themselves that happen through their __setattr__
(e.g.
self.mydict = {} calls self's __setattr__). Mutating the attribute
'mydict'
above "in-place" (via self.mydict['a'] = 1) does not trigger self's
__setattr__, so the ZODB never notices that "mydict" got changed.
There are two ways to handle this. The first is to treat mutable
attributes
"immutably" via assigning to a temporary variable and then making sure
the
persistent container's __setattr__ gets called:
def amethod(self):
dict = {}
dict['a'] = 1
self.mydict = dict # trigger persistence mechanism implicitly
The second is to use the _p_changed attribute of the persistent object
on
which the primitive is set. This explcitly tells the persistence system
to
include the object on which it's set into the current transaction:
def amethod(self):
self.mydict = {}
self.mydict['a'] = 1
self._p_changed = 1 # trigger persistence mechanism manually
Variations on this theme extend to list methods too (e.g. list.append,
list.pop, etc.)
"Custom" classes can certainly persist, they just need

It'd be nice to peek at someone else's solution before running off and reinventing wheels :-) When users proceed from Shopping Cart to Checkout, we create an SQL record for the order. This record holds their billing and shipping information, charge card result code (not the credit card number of course). If you examine the checkout sequence, you'll see that the only way you can leave it (other than by the nav bar, which will soon be fixed too) is by clicking on an image. All of these images are part of the form. Clicking on any image causes the contents of the form to populate the database record. If you clicked on 'next', we also validate your inputs. If your input passes validation, we increment a "nextPageAllowed" SQLSession integer. This controls which page you can move to.. So naturally you can move backwards to any page you've completed, we retrieve the data from the SQL record to populate the form. When you hit page 3, we populate a LINEITEMS table by dumping the contents of your shopping cart (which is an SQLSession dict). During the population of LINEITEMS, we calculate sales tax, shipping costs, etc and record all the costs in the ORDER record. We then display on step 3 the LINEITEMS records and the costs from the ORDER record, since this is what the actual cc charge will be based on.

I run at least 7 or 8 Zope sites of varying shapes and sizes for about a year now and everyone once in awhile I just have to take a moment and reflect upon how much easier Zope has made my "web" life. There are some of my stories (que the music) - Recently someone took notice of a FAQ on one of my sites (thank you KnowledgeKit) and was trying to figure out how I kept it updated and allowed for user submissions. As I told them about the process (submit, email, edit, approve, go live and added to "new FAQs") I just realized how cool the system really is and how much easier it had all been to do in Zope. The kicker was when I mentioned I had the same system for the links (Thank you SimpleURL). They were stunned, to say the least. Go Zope. - My Brother recently had a child and not only was I able to set my new niece up with a area on the family site but gave my Father a username and password and about five minutes of instructions on how to get images into the photo album (thank you ZPhotoAlbum). I went to bed while he scanned away and published a series of pictures all by himself. Not only was he totally impressed with the system but in the content management features. Of course a link went out to all the family to come and take a look. Zope can now add a new tag line "Father Friendly." - I have been slowly getting Zope into more and more projects at work. We are now at about 5 Zope sites. This really shouldn't seem that amazing except for the fact that I in order to build the very first site in Zope I had to battle for about two weeks with arguments, case studies and ultimately putting my job on the line. Now, when building a new site they don't even question what I will build it in. Zope is CEO friendly as well. - Two of our sites at work were built at the same time. One in Zope one in JSP. Everyone worried about the Zope and how it compared to JSP (Tomcat). Fast forward a few months when the consultants who built the JSP site are gone and the two sites need content management and updating. I spent a little time with one user teaching them how to update some stuff with versions etc and they have been happily doing so ever since. The person who is responsible for keeping the JSP site updated has been struggling with code, FTP issues, compiling problems, etc. After about a month of struggling with her updates and changes she noticed the other user easily go in through his browser, do a quick change and make it go live. Fireworks erupted. She had a TIZZY! "DID YOU JUST CHANGE THE HOMEPAGE THAT EASILY? HOW CAN YOU DO THAT? WHY CAN'T I DO THAT?! OH MY GOD!!" To which he simply replied, "I don't know... I think it is cause it is Zope" (not really knowing what Zope was at all). (last one) - We were building a new brochure site (simple, graphic, etc) and the graphic artist who knows a bit of HTML but mostly works in DreamWeaver and has done a few Zope updates and image uploads in Zope before is heading the project. I set up a Zope server for him, gave him a username and password and basically went on to another project. A few weeks go by and I went to check to see how things had been going thinking that he would probably need me to get the data up there and start building the site in Zope. Not only was the site already built with DTML navigation that he had put in for location specific buttons but he was working on the second version of the entire site in a version. I was totally stunned. Just a nice set of stories for you to share with your peers when they ask you why you should/would or do use Zope. If anyone else has similar stories it would be nice to hear them.

Re: [Zope] Microsoft IIS 4.0 and Zope
The easiest thing to do (for me now) is to add Apache as front-end web-server for both IIS and Zope. The access to documentation, well tested and documented rules for rewriting, lots of HOW-TO's, mailing lists etc makes this a good choice - open source rules!

Re: [Zope] ZEXP filesize
peter bengtson wrote: How (and if) is it possible to deduce the total size of a website from the filesize of Exported ZEXP files in Zope? If it's not possible to find a formula for the ratio of zopestuff and htmlstuff, is there any other way of getting a good estimate of "how big a site is"? The size of a ZEXP should be a pretty good estimate. Its structure is quite similar to the object database. The differences are the lack of history, versions, and database index information in the ZEXP. However, it would also be possible to write an external method which computes directly the size of all pickles in a branch. In fact, here's a start: def compute_size(self): oid = self._p_oid jar = self._p_jar p, serial = jar._storage.load(oid, jar._version) size = len(p) for subob in self.objectValues(): size = size + compute_size(subob) return size It won't work at the root of a site, but it will work most other places.

[Zope] security - am I going crazy ?
Few days ago I found that on site that I'm currently working on, everybody can add DTMLMethods and Documents (and maybe do more, I haven't checked yet, but I think it's bad enough !) by simply entering URL http://www.mysite.com/manage_addDTMLMethod?id=q1title=qq1file=qqq1 After that Zope sends 'Location' header to redirect user to 'manage_main'. That (manage_main) causes 'Unauthorized' exception. But that object 'q1' was added !!! I was thinking that it's a bug in Product. (I use LoginManager, LocalFS, SiteAccess). I decided to upgrade my Zope from 2.2.1 to 2.2.4 and upgrade all Products (one good thing so far ;)). No success. So I did fresh install of Zope 2.2.4, without additional Products, with with brand new Data.fs. Problem persists ! I have default security settings, so Anonymous can't "Add Documents, Images, and Files". Of course user can put any DTML in this object - you know the consequences... (and if the folder where this object is located is owned by high-privileged user, then this object is owned by that user too (through acquisition)). I just checked: I can't add Folders this way. What's going on ?!? Have I found very big security hole, or just I'm going crazy ? :( P.S.

Hello, I've just tried and failed to upgrade to 2.2.4 from 2.2.2. A python instance starts up and slowly swallows the CPU, ending with 99% of the CPU. A second python instance starts and doesn't do anything naughty. If I issue a ./stop, the second python instance ends properly, but the first continues to consume all CPU resources. I've tried recompiling it several times, reinstalling Python, but no go. It did once start up properly, but as soon as I tried logging into Zope, python took over the CPU. I'm using OpenBSD 2.8, python 1.5.2, x86, 196MB of RAM, GBs of free disk space.

Maybe this will create a profile report that tells you where it's spinning. Are you sure your waiting long enough? If you have a large Data.fs and you just move it over to a new install, Zope needs to take some time to build the initial database index file. -Michel ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Nothing implicitly dangerous, but it can get confusing if you have

there's a likelihood that it can never go away (you're can never be sure

all instances have been updated).

I think you read a little too much in to the fact that you need to

the
ZODB, it just means you need to treat them specially when putting

For instance, if you were doing this inside of an external method:
def amethod(self):
self.mydict = {}
self.mydict['a'] = 1
(where self is the persistent object that is usually the external
method's
"container")
It wouldn't work as you expected. Although you'd see an 'a' in
mydict
for a
little while in further accesses to it, 'mydict' would eventaully
show
up as
an empty dictionary on the first access of it after it was expired
from
the
RAM cache (after it was 'ghosted'), because the last thing that the

"saw" (via the __setattr__ on 'self' and a subsequent transaction)

[Zope] SECURITY alert and hotfix release
Hi all, Aleksander Salwa has brought a security issue to our attention that affects all Zope versions up to and including Zope 2.2.4. We have released a Hotfix product to address the issue that can be downloaded from zope.org. (Thanks to Aleksander for finding this and to Shane Hathaway for his quick response in resolving it!) The issue involves security registration of "legacy" names for certain object constructors such as the constructors for DTML Method objects. Security was not being applied correctly for the legacy names, making it possible to call those constructors without the permissions that should have been required. This issue could allow anonymous users with enough internal knowledge of Zope to instantiate new DTML Method instances through the Web. The hotfix for this issue is available on the zope.org web site: o http://www.zope.org/Products/Zope/Hotfix_2000-12-08/Hotfix_2000-12-08.tgz We *highly* recommend that any Zope site running versions of Zope up to and including 2.2.4 have this hotfix product installed to mitigate the issue. The hotfix will work for all versions of Zope 2.2.0 and higher. A future version of Zope will contain the fix for this issue, and you will be able to uninstall the hot fix after upgrading.

[Zope] NIST meeting: Defining Standard, Scriptable Objects forCAD/CAE/CAM/PDMCAD/CAE/CAM/PDM
"Defining Standard, Scriptable Objects for CAD/CAE/CAM/PDM"
Date: December 13th
Time: 10:00 AM - 4:00 PM
Location: NIST, Building 225, Room A54
- for directions and maps to NIST, see:
http://www.nist.gov/public_affairs/maps/nistmaps.html
* If you plan to come, you MUST contact Michael McLay, so that
we are sure that the meeting room space is adequate:
mailto:[EMAIL PROTECTED]
- or call 301-975-4099
Background:
Roughly, PDM ("Product Data Management") does for CAD/CAE/CAM
models and related objects what Zope does for the objects that
need to be managed in a typical Web site (HTML docs, etc.).
Problem Statement
The problem is to find an open architecture for integrating and
managing the configuration of computer-aided design, analysis,
and manufacturing (CAD/CAE/CAM) tools, models, and data.
The purpose of the meeting is to evaluate technologies, try to
define an approximate roadmap for building an open architecture,
and establish a ROM guess of (1) how much work may be required to
implement the architecture components and (2) the cost of
developing and maintaining an instance of the architecture for an
engineering organization.
Agenda:
* Engineering Tool/Data Integration Requirements
Steve Waterbury/NASA
* GenCAM: a Standard API for Electronic Manufacturing Data
Michael McLay/NIST
* The MEMS Exchange: Python and ZODB for Management of Complex Objects
Andrew Kuchling/CNRI
* The CADScript/IScript Architecture (and Demo)
Doug Cheney/International TechneGroup, Inc.
* Python and Zope: Architectures and Directions
Barry Warsaw/Python Labs
* Group discussion
- How to incorporate interfaces to Python and Zope components
such as ZODB into a standard PDM architecture
- What enhancements to ZODB, ZCatalog, ZPatterns, etc., can
address functionality and interfaces needed for general PDM
- Which pieces of the architecture make the most sense as open
source products, which ones are most logical as commercial
products, and what interfaces should be standardized to
enable open source and commercial products to interoperate.
Cheers,

there's a likelihood that it can never go away (you're can never be sure

Recently I built a product out of some python classes I wrapped
around 4DOM, and since 4DOM documents do not seem to persist(well the
document
does, but it loses all its children), then I persisted them to the
local
file
system, since I needed to do that anyway for what I was doing.
Setstate
seemed

it was called very often by zope.
Sure, that works... although at that point you're creating your own

I think you read a little too much in to the fact that you need to
"treat
mutable objects immutably" when working with them in the ZODB. This
statement doesn't mean that these kinds of objects can't be saved in
the
ZODB, it just means you need to treat them specially when putting
them
in
the database.
For instance, if you were doing this inside of an external method:
def amethod(self):
self.mydict = {}
self.mydict['a'] = 1
(where self is the persistent object that is usually the external
method's
"container")

So my current understanding would be that any classes you want

need to derive from Persistence.Persistent, and if it is

then
all
should be fine if you call on instances of that object within
you

Re: [Zope] persistence and dictionaries - new light
I tried a few things out it seems the following is happening :
the methods that seemed to be activating persistence when I thought they
shouldn't are called through my handle to the manage_edit ... i.e. in the
product I sent this was anything called within
def manage_edit(self, title, REQUEST=None):
blah
If I call the same methods from another method in the product, and then call
that method from say a dtmlMethod then persotence failed unless I use
_p_changed. This would go along with what Chris mentioned.
So it seems that def manage_edit has a special behaviour, possible linked to
it's binding to
manage_main = HTMLFile('boringEdit', globals()) # Management Interface
which is linked to
manage_options = (
{'label': 'Edit', 'action': 'manage_main'},
hopefully someone has an answer to that.

RE: [Zope-dev] SQLAlias Memory Leak?
OK, I've put this into the Collector. I'm intrigued as to what the operating procedure is with the Collector though - there appear to be a large number of Pending jobs. Does that mean that Digital Creations haven't even looked at them, or that they just haven't done anything about them? The current Collector is very poor about providing visibility of what gets done. Quite a few bugs get closed out - check out the CHANGES.txt for each release. Each entry under "bugs fixed" generally represents a closed Collector item. I agree that it seems like there are a lot of things in the Collector, but realize that they are not all open and shut things. A fair number are feature requests rather than bugs, and some of the bug reports are in states that are not very visible from the public view (pending more info from the submitter, etc.) We hope to move to using Tracker in the future to make such things more visible. That said, there is a finite amount of resources that can go into Collector management at any one time (though with recent growth that should improve over what it is now). I actively triage the Collector before each release looking for reports that are high-impact (like memory leaks) to make sure they get fixed. I do plan to get to this for 2.3. We can't, however, always get to each issue the day it is submitted :) http://classic.zope.org:8080/Collector/1772/view This is causing big problems with our site, and we need to resolve it pretty desperately. I guess the another solution would be to ensure that all calls to SQL columns are the same case as in the database, but with around 500 ZSQLMethods - that is a daunting task. I have a test suite written that verfies this - it actually appears to be some interaction with the Record extension class (as SQLAliases don't leak if you access them from a plain ExtensionClass.Base-derived class). Hopefully I'll have a patch or workaround for you today.

For example, try: parent._checkId(name, allow_dup=1) except: raise 'Forbidden', sys.exc_info()[1] -- try: parent._verifyObjectPaste(self) except: raise 'Forbidden', sys.exc_info()[1] Lastly, where are properties that can be set and put using webdav.

Surely you jest ? I may be out of line, I am quite new to Zope and have
only made a few python products, but the nice thing I felt Acquisition.Implicit
gave was a sense of being able to put a method into an environment and let it
"discover" what was around it. Aquisition.Explicit I thought was where you
knew specific things about your environment and wanted them from there instead
of what you had brought along yourself.

[Zope-dev] using SybaseDA to connect to MS SQL
Thanks to everyone for their assistance yesterday. I feel like I'm really close to making this work now, but I can't get the Product to connect. I always get "Invalid connection string". One thing that puzzles me is the distinction between 'Server' and 'Datasource'. If Datasources are what we're defining in the interfaces file, that looks a whole lot like Server. I've seen PHP help pages dealing with these Sybase libs and MSSQL; somehow they only need to specify user, password, and database. TIA for any assistance you can offer. What I've done: I have successfully compiled the SybaseDA product, with Sybase libs, etc, set SYBASE and LD_LIBRARY_PATH environment variables in Zope startup. As far as I know, I have created a valid 'interfaces' file. It looks like this: spindler master tcp eth0 xxx.xxx.xxx.xxx 1433 query tcp eth0 xxx.xxx.xxx.xxx 1433 where spindler is the hostname of my computer, xxx.xxx.xxx.xxx is the dotted-quad of my sql server. On the windows side, the SQL Server has Network Utility on, port 1433. (it refers to itself as SPINDLER, does case matter?) I created a test database with user/passwd and so on. The output I get upon connection: -- Invalid connection string: database: quux, password: x, server: spindler, transactional: Y, user: neilk Traceback (innermost last): File /home/neilk/Zope/Zope-2.2.4-src/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /home/neilk/Zope/Zope-2.2.4-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/neilk/Zope/Zope-2.2.4-src/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook File /home/neilk/Zope/Zope-2.2.4-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/neilk/Zope/Zope-2.2.4-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_adddcSybaseConnection) File /home/neilk/Zope/Zope-2.2.4-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_adddcSybaseConnection) File /home/neilk/Zope/Zope-2.2.4-src/lib/python/Products/SybaseDAv2/DA.py, line 100, in manage_adddcSybaseConnection File /home/neilk/Zope/Zope-2.2.4-src/lib/python/Shared/DC/ZRDB/Connection.py, line 132, in __init__ (Object: RoleManager) File /home/neilk/Zope/Zope-2.2.4-src/lib/python/Shared/DC/ZRDB/Connection.py, line 161, in edit (Object: RoleManager) File /home/neilk/Zope/Zope-2.2.4-src/lib/python/Shared/DC/ZRDB/Connection.py, line 240, in connect (Object: RoleManager) File /home/neilk/Zope/Zope-2.2.4-src/lib/python/Products/SybaseDAv2/db.py, line 147, in __init__ File /home/neilk/Zope/Zope-2.2.4-src/lib/python/Products/SybaseDAv2/db.py, line 306, in _error BadRequest: (see above) -- Neil Kandalgaonkar, ActiveState ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

I really liked the ZEO examples, but RB where's this going? It is the most expedient way to start opening ZODB development, including ZEO, up to a larger audience of developers. Andrew's project will focus primarily on packaging, testing, and documentation. In the short term, the easiest way to accommodate his needs are to have his own SF project. The plan is to have the two different CVS repositories integrated at the level of working directories. Developers will probably end up with checkouts of both CVS trees, knit together so that Andrew's setup scripts and the like encapsulates the source code from the DC tree. (This setup makes the initial checkout a little complicated, but cvs update should work normally.) Andrew, Jim, and I and the rest of the PythonLabs team chatted about these plans over Chinese food on Wednesday. PythonLabs plans to get much more involved in ZODB development.
