This blog post is basically nonsense. It is three years old, application
site configuration are clearly documented in the
every expressive Pyramid documentation and you usually never need to get in
touch with the Pyramid sources yourself.
I am using Pyramid in small and big projects for years and I _never_ had to
look into the Pyramid source code for achieving
some functionality or whatever! And this is likely true for your
applications...

Who care what is happening under hood and why? As stated above: there is
usually no need to look under the hood of Pyramid.
If you have a reason to do so: please your usecase. Pyramid has great
documentation (compared to Zope & friends) and does not require
to check the implementation in order to understand how Pyramid works. IT IS
DOCUMENTED.

Most of your point are basically wrong and  nonsense based on missing
information, lack of experience and your special view on things as we have
seen in your annual weird postings over the last decade.

It has? Never heard of that...this is _your_ own opinion.

Pyramid gives me as a programmer the freedom to choose the database, the
routing mechanism and the template language that
I need and that I want for my projects. It does not tell me to: you have to
use this and this...this is _freedom_ and not an identity issue.

Constraints are perhaps a good thing if you are a programmer with a very
limited horizon
or if you need holding-hands with having only only possible option for
doing database, routing and templating.

Once again: bullshit! Complex application code remains complex independent
of the web framework. Provide some evidence for your claim.

So much bullshit, FUD in one sentenceprovide evidence please.
Pyramid is usually every easy to understand when it comes to the Pyramid and
webframework related aspects. Bad application code can be written with
Pyramid
and Grok.

We have really *enough* dead Zope related mailing lists. Nobody needs
new lists. For a project with very little effort going on and with a
stagnating audience: what we have is good enough.

Running Zope on a public network behind a reverse is highly recommended

Those are broad questions that can not be answered seriously if you

Perhaps

At least Zope 2 apps have a useful ttw-inspector for threads and

The number of worker threads (and clients) basically depends on how much
concurrent requests you have. Four worker threads can deal with 100
requests/second
when each request can be processed fast. Long running requests will
block other
requests...so you must measure how long a request takes in average..then
you can do your own calculations. The cache size depends on various
factors..
you have to check the ZODB activity in order to perform fine-tuning.
There is neither a golden bullet nor a recipe for the perfect
setup...start with
a common setup of two clients or so and see how far you can go...then
adjust
your parameters over time.

#concurrent requests, #concurrent writes, reads, the nature of the

[Zope3-Users] [ZCML] Issue with conflicting browser:page decl

[Andreas Jung]

Hi there,

I'm really puzzled about the following ZCML configuration conflict
where I am trying to override a browser:page for defined in
dateable.chronos.browser.events.EventListingView.upcomingEvents
with slightly customized implementation within my own idg.theme package.
Both ZCML configuration are of course identical except the the 'class'
is different.
Anything I am missing?

Andreas

Is this related to Zope 2 or Zope 3? PT in Zope 2 should not reload if
debug-mode is disabled.

If you are not using ZEO: look at the fspack.py

Right. The splitter  and query parser use different approaches for
splitting words and dealing with non-characters. This is subject
for a major cleanup with the next TXNG 3.3 version to appear

The z...@zope.org is meanwhile a pretty low-traffic list and I am

[Zope3-Users] [RFC] Merging zope3-users list with z...@zope.org list

[Andreas Jung]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hereby I propose to abandon the zope3-user list  and merge it with the
z...@zope.org mailing list.

Why?

 - getting rid of the artificial distinction between Zope 2 and Zope 3

 - phasing out the term "zope 3" in order avoid confusion

 - keeping user questions on one list since there is often an overlap
   between Zope 2 and the Zope component library (aka Z3)

 - one "user" list is enough (as we already have merged the
   zope3-dev list into the zope-dev list)

Thoughts?

Keep in mind that the Zope component became very mature over the last

Re: [Zope3-Users] Is zope3 dead?

[Andreas Jung]

Replace "Zope 3" with "Zope component architecture" or "Zope web 
components". That's where we are: Zope 3 was always a set of components. 
Since some time every individual module has its own
lifecycle and its own releases. Those components are widely use in 
various projects (Plone, Zope 2, Grok, Repozse, other Python projects). 
Don't expect any further "Zope 3" release - expect that the individual
components will ongoing improvements over time. The core components are 
very mature and the goal splitting Zope up into pieces is basically 
achived (according to Jim Fulton)

For some time, I have a bad, worrisome feeling that Zope3 development

Today looked to zope wiki and discovered that there are virtually no new

zope 3.4.0c0 is not even a real release, but a release candidate.
Someone would say: /hey, but maybe the development has just been
decentralized? Zope 3.4 is the first eggified release, so maybe the
development just moved to eggs (z3c.* and others)/.
But I digged deeper and searched for some stats of Zope3-Users traffic,
thanks to google. What I found I have published on a chart at
http://pmiblog.blox.pl/2008/12/Is-Zope3-Dead.html. The traffic is at
least half lower in 2008 than in 2007.

Maybe the traffic moved somewhere else - to Wiki? This hypothesis
haven't worked: I looked to zope 3 wiki and:

* the last new topic is 3 months old
* last month there is one edit of a topic
* After July 2008 there was not a one month with more than 5 edits.

To summarize: It seems that zope3 development and engegement have been
stalled for over half a year.
Any thoughts? Have I missed some switch to other communication channels?
Or maybe grok really took away all hearts and souls?
What are the causes of the slowdown? Or maybe I just misinterpret the
symptoms?

Re: [Zope3-Users] Zope3 and SQLAlchemy

[Andreas Jung]

Use zope.sqlalchemy for integration with the Zope transaction system.
You can directly use the declarative layer of SQLAlchemy out-of-the-box.
This is basically you want.

I'd like to use SQLAlchemy to handle this, and I've seen that several
packages are available : z3c.zalchemy, z3c.sqlalchemy,
zope.sqlalchemy...

So my questions are simple :
  - what package is the best to plug into my Zope (3.3.1) application ?
  - do all these packages handle the same features ??

Thanks for any information,

   Thierry Florac

Re: [Zope3-Users] Will new release of zope3 include TSL/SSL in zope.sendmail

Hi ALL,

When will the next release of zope3 will be? will there be a zope3.4c2?
By the way i wish to know whether next release will include the latest
release of zope.sendmail which has TSL/SSL feature.

I have noticed that last release, zope3.4c01 was on 31 Jan 2008.

http://www.zope.org/Products/Zope3/3.4.0c1

And the zope.sendmail has trunked SSL/TLS feature on 19th Aug 2008.


You mean 2007!


http://svn.zope.org/zope.sendmail/trunk/src/zope/sendmail/mailer.py?rev=92747&sortby=log&view=log


So its obvious that zope3.4c01 don't have SSL/TLS feature in its
zope.sendmail. And i have seen some other many other fixes in the
zope.sendmail that enables it to work well with gmail and similar



Those changes should be at least in the latest zope.sendmail 3.5.X
releases. In the time of components and buildout you should be able to 
upgrade the zope.sendmail dependency easily yourself.

I think this might be a quick workaround for my production instance.


At least in Zope 2 there is a variable "retry_max_count' within in the 
ZPublisher. Likely there is something similar within the Zope 3 publisher.

I would grep for "3" :-)

How about application specific conflict resolution (_p_resolveConflict()
hook)? How about using a nested folder structure in order to reduce the
number of conflicts?

I thought about _p_resolveConflict, but I don't see how to catch up this
conflict on my BTreeFolder derived class. Maybe I should give up the
BTrees and use an ordinary container implementation?



This would make your problem even worser.

Yes, that's what I thought... :-(
So is there an easy way to "intersect" the results of several distinct
queries, so that the results order provided by TextIndexNG and following
ranking is kept ??


Intersection is likely possible. However I don't know about the 
implementation of hurry.catalog or the other related Zope 3 components.

Performing two queries and intersecting the results (e.g. given by paths,
UIDs or whatever) is basically supported through the various BTree types
or Zope or by Python's set module..

- how can I use TXNG ranking feature when running a single query against

Search for a provider where you can get shell access and where you are able

Python 2.4 is still the only supported Python version for Zope 2 and Zope 3.
You have to install in your case a self-compiled Python 2.4 and compile 
your Zope with this custom interpreter. That's the way to go right now.

[Zope3-Users] Using zope.component outside Zope 3-how to bootstrap the registries

[Andreas Jung]

I am trying to use zope.component (Zope3 3.0) within a Python module
(not running the whole Zope 3 boilerplate). I want to register a utility.
What is the correct way to setup the registries (in particular the Utility
registry) in order to register utilities?

hmmm...  i don't guess i disagree with those contentions directly, as
they apply to sql.  but i do think that a query language of some kind

questions on applications i've built that would be more easily
answered with a query language, rather than specific python scripts or
catalogs.  the trouble with catalogs is that until you know you're
going to want to index on and query certain information, you probably
won't build an index for it in the catalog...  and it's a non-trivial
amount of work to make querying the zodb, even with hurry.query, work
the right way.


In reality you don't want to search inside a RDBMS for unindexed data
for performance reasons. This is even more true for Zope since you have to 
read all data of the ZODB..this will be totally inefficient especially

for large installations. Zope object can be very complex: attributes can be
basic Python types, Zope BTrees, hierarchial data etc...how will you define
a query language that covers all use cases? In Zope 2 we have something 
like AdvancedQuery to specify almost generic queries for the ZCatalog..I 
think hurry was inspired by AdvancedQuery. Of course you can define 
something that implements a particular subset of all possibile types and 
query types . But when it comes to the point where the functionality is too 
limited you end up writing you queries based on the functionality the core 
engine gives you.

Why do you think it would be necessary or helpful to define a SQL dialect 
(which is designed for a relational data model and not for an 
object-oriented model)? The usecases for SQL are different from the 
usecases when you deal with the ZODB. I doubt that are benefits for 
real-world apps for such an approach.

First come, first serves. There is no fancy synchronization. If two threads 
are trying to modify the same object then one thread will receive a 
WriteConflict error. It is up to the app to deal with these kind of errors. 
In the Zope 2 world Zope tries to re-do the current transaction for up to 
three times before the ConflictError is passed up to the application.

My personal idea of ZODB is some kind of a file system. You can create
container and items. All this is stored in a file called Data.fs. This
file system is mounted on startup by the Zope application server.


The ZODB by itself does not know of hierachies. It's basically a persistent 
storage of key-value pairs. Zope itself introduces the hierarchy and a 
filesystem-like layout by introducing folder-like objects (e.g. 
OFS.ObjectManager).

It's even worser (due to a calculation error): 10 billion would mean 310 
tx/second but 100 billion would mean 3100 tx/second...you should look for 
something _bigger_.

What architectural things have affected performance?   I general we're
looking at using an RDBMS, but we're trying to get a better feeling of
when we can use the ZODB and when we should stick to the RDBMS. I like
the ZODB because of it's versioning information in particular.



We have various datasets:

1.  Transactions: 10-100 billion objects


per day, month, yr?


2.  Users: 10-100 million objects


up to 1-2 million objects seem to be common for large sites nowadays


3.  Contacts: 100,000 objects
4.  Customers: 100-1000 objects


Possibly you might consider a hybrid solution using the ZODB and a RDBMS.

The basic use cases are as follows:

Shoppers can "browse products by category"
Shoppers can "search for products"
Shoppers can "add products to cart"
Merchants can "import product lists from Excel/Text file"
Merchants can "manually edit products"

We expect to service 1M purchase transactions a year, and expect to

I would go for a RDBMS.

This depends likely on _your_ usecases. Data can be stored in a RBDMS, in 
the filesystem, in the ZODB...every storage has its pros and cons..without

knowing your usecases there is only guessing what might be best for you.

Hi,

currently I'm trying to use TextIndexNG3 in Zope3. I'm able to add a
"Ting3 Index" to my catalog but there are some problems:

1. After I added a single object, the catalog statistic (Advanced-Tab)
showsa table like this:

index | document count | word count
--++---
textindex | 1  | 15
ting3 | 1  | 1

   Why is TextIndexNG3's wordcount 1? The object I'm trying to index
   contains 15 words.


Look yourself at the indexed content. There is now TTW support to look
at the indexed content like in Zope 2. You have to use the API for the 
lexicon to perform further investigations.





2. Where am I supposed to enable/disable all the ting3-features (i.e.
   stemming)? There are no configuration options when I add the index to
thecatalog.



The _real_ index implementation is in textindexng/index.py which provides 
access to all parameters. ting.py is a _wrapper_ around the index 
implementation to integrate it with Z3. It was provided by Ivo I think.
The wrapper likely needs more work. Since it is a very think wrapper it 
should not be so hard to pass through all possible parameters..I won't work 
on this issue...patches and contributions are welcome.

One request = one transaction. I think there is no way to get around (this

Make clear separation between your core implementation which should not

[Zope3-Users] Advanced usage of Z3 schemas...

[Andreas Jung]

Hi,

I am currently thinking about for a new version of PloneCollectorNG based 
on Zope 3. The currently implementation uses per-instances schemas 
(acquired from a parent object managing the schema). How would you do that 
in Zope 3?
Another question: in Zope 3 we have FieldProperties that automatically 
handle setting and getting values. This implementation stores the values as 
instance attributes. What would be the recommended way to store attributes 
in a RDBMS instead inside the ZODB? By introducing a new RDBMSFieldProperty 
that handles the set/get methods in the same way as the FieldProperty 
implementation?


Thanks,
Andreas
