The migration code tries to sniff the encoding (it knows about ISO-8859-15 and UTF-8). A custom preferred encoding can be specified through the environment variable $ZPT_PREFERRED_ENCODING.

But it is - in fact my local copies have the hack where I used

that - default_zpublisher_encoding is much better here.
Kate (as webdav editor client) plays very well with that.
On the other hand there is code available that tries to obtain
the encoding from the XML preamble (sniffEncoding)...and the very other
hand
Yes this double encoder marking is a mess. We need to be able to
provide a fixup (just like the infamous base-tag)
there is still a problem with this method since the encoding can be
determined by the BOM (if available)...this currently not handled through
the code...I think I'll have a closer look at the code once again this

BOM is only for filesystem unicode of some 16-bit variants. Nothing
you really want to send over the wire (although you can).
But after all its just another encoding so it would be a matter
of setting the encoding correctly.

Re: [Zope-dev] Username/userid separation
Am Mittwoch, den 03.08.2005, 21:01 -0300 schrieb Leonardo Rochael Almeida: Hi, I've started the lra-userid_username_separation-branch (from Zope-2_8-branch to start from a stable point) in order to implement proper userid/username separation in Zope. I don't intend to change the default user folder implementation, just the ZMI interface for owner and local roles so that they keep using userid for storage like they currently do but use usernames for display (specifically acl_users.getUserById(id).getUserName()). The intent is to never leak the userid to the ZMI (except for url query strings and such), and to never store the username persistently. The motivating usecase is an LDAP (eDirectory) authenticated system where the username for a user can change, but not the internal ID (a string). This will also help ActiveDirectory integration, which also has an internal ID to reference users. I remember there being a discussion about this in the list archives, but a Google search didn't help much. Are there any other projects in this area that I should colaborate with instead of duplicating efforts? Are there any considerations I should be aware of? Are you aware of the PAS (Pluggable Auth Service) project? http://cvs.zope.org/Products/PluggableAuthService/ They already have a separation of uid and login.

thank you. By the time I got it working when I first
used filestorage, bootet zope so it created all folders
as it wants and then stop zope and use that Data.fs
for ZEO. Then I was able to mount the zeo as /

[Zope-dev] Re: [Zope] WISH LIST - idea of new, DTMLRelation object
Hi Jaroslav,
perhaps you want to use dtml-with rootfolder ...navigation.. /dtml-with
?
Rootfolder could be the object you want to be the root (of course)
or in case of ZopeRoot, you get it via REQUEST.PARENT[0]
However, before beating the dead horse, you should consider
replacing your routine with a python script, which could
also use ZCatalog in place of ObjectValues() - this saves
Memory and time since not all Objects have to be activated.
This approach would also help you to go the way from
DTML to ZPT which is recommended.

Hi all,
I have an idea of new Zope DTML object with specific things. Dear Zope
developers, please take attention to following lines:
Imagine folder structure as

DTMLRelation
image.gif
/folder11
/folder111
/folder112
/folder12
/folder2
/folder21
All three DTML* contains same code:
dtml-in objectValues('Folder')
dtml-var idbr
/dtml-in
img scr=dtml-var absolute_URL/image.gif
Imagine what is doing that DTML Document or DTML Method are called from
inside of /folder11. DTML Document make bad, but still functional (due
acquisition) link to image.
But DTML Relation will still give that same output, independent from where
you call it:
folder11
folder12
img src=http://domain/folder1/image.gif;
Output is still independend from where you calling that DTMLRelation and
give you right URL paths (relative or basolute).
I think that DTML Relation (or you can call it better) should be very
usefull, for example:
1. for navigation structure when you want to have constant navigation
buttons what are dynamically generated from folder structure that have
strong changes in any folder names
2. for image menus, where it give right path to images folder instead of
acquired images
etc. (I now, you can specify path with dtml-var BASE1/images/image.gif)
Many thanks for your kindly attention.
If it have simple solution by standard DTML code, let me know that code,
please.

Oktober 2001 12:11 +0200 Itamar Shtull-Trauring [EMAIL PROTECTED] wrote: Actually, this brings up this idea I had - Zope should replace medusa with Twisted. Why, you ask? 1) Twisted separates transport from protocols, and the event loop it uses is extendable and generic. That means: - It can run on Jython (using threads, someday with java.nio), and it can be integrated with the Tk and GTK event loops. - Your protocol doesn't have to worry about the transport - Twisted supports SSL, TCP and unix domain sockets right now, without having to make any change to the protocols. 2) Twisted is designed to run multiple servers and protocols at the same time, and these can be changed at runtime. It already includes pure python support for HTTP, FTP, LDAP, SMTP, POP3, DNS, telnet, AIM TOC, and IRC, all integrated with the main event loop (all have server support except DNS and LDAP). Adding new protocols to Zope is not easy, at the moment. 3) Twisted is being actively developed and extended. medusa less so. 4) Good integration with threads - while event based, twisted has a very nice model for dealing with threaded apps. 5) Twisted has Perspective Broker, an async.ready remote-object protocol that supports caching, object migration, and remote messaging, with integrated authentication and authorization. And it ideologically meshes with the object publisher notion in Zope. No, really :) Twisted already includes a high-level web framework, but Zope probably would not use it, and instead build its own on top of twisted's low-level http support. ___ 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 ) ___ 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 )

The second client to start will accept connections, but never responds with anything. Zope: 2.3.2, ZEO: 1.0b3, Windows 2k for clients, Linux and Windows 2k for storage server. Is there a better solution? If not, has anyone come across this problem?

Re: [Zope-dev] Professional Sites Using Zope??
Hi Jawad, we use the existing heterogenous database system of your company for a B2B e-commerce solution. With zope we had the flexibility to do so and archive releability too. For access to databases we use Merant middleware together with ZmxODBC. Unfortunately the service is not open to the public. It has come out only the strange databases are somewhat a bottleneck for the system. However, we handle around 100 customer at any given moment round the clock. The other site we built with zope is our companys public web site. You'll find it on http://www.peacock.de/ HTH Tino Wildenhain --On Mittwoch, 16.

But the file sketch shows (I hope) what I had in mind for making this work: programmers would call a bunch of functions that would put together a relational mapping tree. Now, in our discussion yesterday we decided ORStorage wasn't the right way to achieve relational mapping because there is no way for the database storage layer to have any context just given an OID. If we instead consider writing a replacement for the stuff that's mainly in Connection.py, life gets a lot simpler. At this level it *is* possible to know the parent OID of an object, though the current codebase does not use this opportunity. Also, we wouldn't have to pickle and unpickle unnecessarily. So, if we have context, the relational mapping tree can work. It would turn Zope into a purely relational application server, which a lot of folks apparently want. ;-) Oh, do they? ;) Me dont :-) Regards Tino ___ 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 )
oodb philosophics ;) was: Re: [Zope-dev] Experiments with ORMapping
Hi shane, I think the motivation people want an RDBMS storage beneth zodb is because they understand RDBMSes these days are performant, relieable and can quiete easy maintained. I've seen Java implementations using this approach to achive persistens using as example Powertier[tm] to explicit map oop data to an RDBMS. I didnt like it because you have to map your objects each time you create a class, keep in mind not to infere with others etc... Would it not be better to improve the abilities of the Filestorage to handle updates better? May be most of the storage system in C? With logfiles like modern RDBMSes use to incorporate fast changes? However, to avoid pickling/unpickling and may be to update on attribute-change, we need the approach you mentioned. What about using a real oodb for zope? Dont remember any particular product name, but I heard something. Regards Tino Wildenhain --On Donnerstag, 10.

Which part of ZPatterns are you referring to? The idea is to (generally) put all instances of a class in a certain table. But the implementation details having nothing in common with ZPatterns. Or do we want to make some automatism to get tables created and destroyed according to ZClasses needs? I was thinking there would be a default table where everything gets stored by default. A programmer then tells the ORMapping about specific classes and how to store them. So, if we have context, the relational mapping tree can work. It would turn Zope into a purely relational application server, which a lot of folks apparently want. ;-) Oh, do they? ;) Me dont :-) You know, it might be possible to get a team together to implement this. How many out there would be interested in pursuing it further? IMHO it's not as much work as it sounds at first. Zope being so object-oriented, you really can replace one of its most fundamental assumptions (an OODBMS) with something else (an RDBMS) without a huge effort.

Re: [Zope-dev] another Zope hanging..
Hi, most problems with hanging zope come from external RDBMS-access. You wont see anything useful in the logs because there are some objects published before the *sql-method is hanging. If you have a monitor program for your database, you see many blocks on tables or rows during this times. I expect it with DB-adapters not fully thread aware and - with to high timeout. In fact it seems we need timeoutsockets and asynchronous rdb-access. If one thread is hanging, in the scope of 120 instructions, zope has to wait before the global interpreter lock frees. So if its stuck in the call of a C library (database adaptors are most in C) it cannot continue until the call returns. Regards Tino Wildenhain --On Donnerstag, 3.

Alright... so you're getting an OSError 11, and you're using Zope 2.3.1. errno 11 is temporarily unavailable which means about as much as foobar feeblefar as far as I'm concerned ;-). great :) Though you've said the -M log isn't helpful here, I think it is. If this is happening when a certain method is hit, or at a certain time of day, or when a certain number of connections are reached, etc., the -M log in combination with requestprofiler can help determine this. Otherwise it's a guessing game. ok, just thought that maybe some exception can be caught.. I will try to use requestprofiler now, though I checked the -M log before and around that time there was no obvious problem.. (also it's not loaded at the moment and it's happening here and then, don't see a pattern there..) I will check (and maybe change the mysql adapter, as I recently had problems with it on a sun machine, too). thanks anyway :) Christian ___ 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 ) ___ 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 )
