[Zope-dev] Policy for Collector-Issues 545 and 1217?

2004-04-25 Thread Maik Jablonski
Hi,

there are two collector-issues related to problems when Zope-Objects get ids
like 'content_type' or 'URL1'. I think this problem exists for all names
used in the REQUEST-object or general acquisitionable attributes of
ObjectManagers.

http://zope.org/Collectors/Zope/545
http://zope.org/Collectors/Zope/1217

I don't think that these issues cannot easily be solved in Zope2 without
breaking the whole acquisition-magic.

What to do? The problem exists, but a fix is hard to find... if at all.
Accepting? Rejecting?

Cheers, Maik

 Maik Jablonski of the german speaking Zope Users Group
 DZUG issued a pretty bleak outlook for the future of
 Zope. What are your oppinions?

Hi to all,

I'm not able to respond to all mails in this thread due to a trashed
shoulder (very unlucky cyclocross-crash last week), but I'm feeling the
need to make some simple remarks.

1) Chris is right: Yes, I've had a bad day...;)

2) My initial mail wasn't intended for zope-dev. So I'm a little bit
suprised that it made it to this list. If anyone feels offended (esp. Jim),
I'm very sorry, but if I want to complain about Zope2/3 on this list, I
would use other words. The initial mail (written in german) was written in
a state of fear (not anger). The translation (and maybe my mail itself)
didn't transport my fear about the future of Zope very well I guess.

3) To say it clearly: I would have never started the German Zope User
Group two years ago if I were not totally convinced of Zope (the
technology  the community). Bringing up a community in Germany (with
several big conferences, etc.) was a lot of work (believe me), so I don't
feel as a usual freerider who only complains but does not give something
back to the community. But my resources are limited as well, so I can't
take additional tasks as documentation, release-management, etc.pp... If
this means I'm not allowed to say anything critical about these points then
I'm very, very sorry making any remarks...

4) Stephan, you're right, I did not study Zope3 (and the zope3-dev-list)
very well. My initial approach to Zope3 ended with the impression: huh,
complicated stuff, but I don't have time to work it out in the moment!
Then I've talked to many people who said similar things about their first
experience with Zope3 (maybe I've talked to the wrong people, than this is
my fault, sorry again). So I came up with the impression: yeah, Zope3 is
cool, but complicated (stated as 'academic' in my mail)! (at least if you
don't have the time to work things out by diving into the source). And if
you run several mission critial applications you don't have time to look
into this kind of new stuff. But you're right, Stephan: If you want to stay
in technology business, you have to invent (read: improve by a complete
redesign) the wheel many times. So I don't think that Zope3 is useless for
the future of Zope.

5) But there's some kind of a bad impression in my mind (maybe it is without
any foundation, than all things are in best state): Zope2 isn't maintained
very well anymore due to limited ressources (bug fixes, documentation, see
mail from Andreas), but Zope3 isn't production ready at all. So if you talk
to people making the decisions in the IT-business they say: Zope2 seems to
be a dead horse, Zope3 is just a child which learns to run... Let's settle
our business on more approved technologies like Java / Net (or even
PHP...;)). We can't wait anymore... This kind of frustrating impression
made me writing the mail about the future of Zope, because I'm in love with
Zope and not Java, Net or PHP...

[[[6) Just a personal note to Stephan: You're right again about the
quickdirty design of some of my products (esp. Epoz, I have simply no
knowledge about JavaScript at all (and I don't like it), but Epoz seems to
do a good job for many people until Kupu is finished). 

My job (read: strength) is custom-application-development (talking to
customers and reading their minds, developing prototypes to track down the
issues the customer meant and didn't told me and didn't dream of etc.pp.,
developing  securing  maintaing web-applications which need to work in an
environment with 20.000 students  2000 office-workers etc.), not
application-framework-design-nor-development, so my products are just
some wired by-products of my daily work. About MailBoxer: If you think
MailBoxer is just another mailinglistmanager (like mailman) you didn't
get the idea of it... MailBoxer is a lightweight mailinglist-framework (!,
yes I've done some kind of framework, it can be done better, but it solves
my problems this way) which is built on the power of Zope to achieve some
things you can hardly achieve with Mailman (at least I wasn't able to to).
So I've reinvented the wheel once more to solve some of my
application-needs...]]]

Hope this made things a little bit clearer... I didn't want to attack ZC /
Zope3-devs / the community or anyone else. I'm just fearing that we miss
the train for Zope2 AND Zope3 in the moment... if you don't think so, I'm
fine...:)

Keep zoped,

Maik

 At a minimum, having a clear and documented policy would provide
 the benefit of 'no surprises' - if you disagree with the policy,
 or some aspect of it, you would at least be able to plan around it.

Very good idea...:) If all Zope-Admins can read before an installation:
Security exploits will be exposed to the public as soon as they're
resolved in the CVS everyone will  should run Zope out of CVS.

My point was: Give people a chance to react on exposed security flaws. The
statement above will do that because people should be prepared...:)

[Zope-dev] Resolved security-related collector issues for the public?

2004-01-21 Thread Maik Jablonski
Hi,

there were several security-related fixes in the collector (and the
collector-mailing-list) in the last days. Normaly security-related stuff is
not visible for the public... and this seems to be good to avoid exploits
etc.

Lots of security-stuff is fixed now, but I don't think that all people will
migrate their servers as soon as possible (due to limited time, the
experience of the Zope-2.6.3-desaster, vacations, etc.pp.). 

With all the mentioned security-exploits in the collector out there, the
probability of attacks will rise. And I don't think that this will shed a
good light on Zope.

My proposal: Can we have a delay for making security-related fixes public?
Just a month or two or so...

Cheers, Maik

 How exactly was ZC
supposed to release a new version of Zope with the fixes but at the
same time not divulge the nature of the security flaws?  Release an
obsfucated binary distribution and say Trust Us?  That doesn't sound
very much like open source.
In the past we had something like Hotfixes for security problems... Easy 
to install for the average administrator and that's it.

I can check out the current Zope from a CVS... So getting security fixes 
is no problem for me. But I'm not an average Zope-Admin or -User.

There are many admins / users out there who aren't able to do this 
(maybe they should learn it, but that's another point). Installing Zope 
2.6.3 was a big mess (even renaming in the ZMI was broken) and most 
people rolled back to 2.6.2. Some people run even 2.5.1 (lots of 
Debian-Users etc.).

If we don't have a easy-to-install-security-fix for such people (or a so 
called stable release, which works out of the box) we should a little 
bit cautious about releasing exploits. That's my point...

Brian Lloyd wrote:
and all of the items considered important to

Hi Brian,

I've talked to Andreas at EuroPython yesterday about the ZRest-Product, 
which was originally written by Richard Jones. Andreas added this to 2.7.

In my opinion we should go for a more general 
TextDocument-Content-Type, which allows switching between 
RestructuredText, StructuredText and PlainText (newlines_to_br).

I've looked into ZRest-Product on my travel back from EuroPython and 
would think, that the additional switchable-text-format-support could be 
easily integrated. Should I provide patches? I would also provide the 
missing icon for the ZRest-Product.

Another one: If I implement the described changes, we should switch 
ZRest to a more general meta_type: TextDocument (formerly 
ReStructuredText Document). How about that?

I think that this is no showstopper in general, but switching the 
meta_type could be one, if people start to work with 2.7...

Your question has nothing to do with developing the Zope Application

ask on [EMAIL PROTECTED]

Your question:

Place a DTML-Method into your Zope-Root with:

dtml-var _['index.html']

(you can add some condition tests for index.htm of index.html if you

Hi,

http://collector.zope.org/Zope/697

should be set to critical, because it results in loosing essential data.

Case: We store much of our Keywords etc. in multiple-selects. 
Everytime a user edits and saves such a multiple-select, all items with 
NON-Ascii-characters [german umlaute for example] won't be shown as 
selected cause of the bug. So the next Save Changes will loose all 
this items.

I don't know where's the best place to fix this issue, but it need to be 
fixed as soon as possible...

Abel Deuring told me a patch, which solves the problem in the meanwhile:

Does it make sense to get ZCTextIndex fixed (there seems to be a patch in
the collector already) or should I go with TextIndexNG? If yes, is it ready
for production environments?


hi,

I've submitted a patch for locale-support for ZCTextIndex:

http://collector.zope.org/Zope/597

I run this patch on a production site [most content is german] without 
any problems. I think, if all test-cases for ZCTextIndex succeed with 
this patch, it should be merged into the next official release so all 
european zopers can use ZCTextIndex without patching it... in my 
opinion: high priority for this one done :-)

cheers, maik

The main reason I have not merged this already is that I lack a sample to make 
a new test with. If someone can provide me with some content samples that 
break now, but work with the patch, I will make a new test and checkin the 
fix for 2.7 perhaps 2.6.1 if desired.

hi Casey,

try some words with german umlaute. things like:

mülltonne
waschbär
behörde
überflieger

the last one will work without the patch. explanation: the first 
character is splitted away [non-ascii-character] [both for storing the 
word in the Lexicon and resolving the query-words through the 
queryparser]. so it will in both cases end up in

berflieger

searching for 'überflieger' will give you correct results. this is the 
reason, why some people think, that ZCTextIndex works with german 
'umlaute', but it does not...;-)

hope this is helpful.

cheers, maik

 Hello All,
 
 I am trying to FTP images into various zope directories. Some of the
 images show in zope as 0k. When I check these out in the file system
 they are greater than 0k and I can view them. So I put like a 5 second
 sleep in my script before every image is ftp'ed. This method did reduce
 the number of 0k files however it did not eliminate the problem. 
 
 I do not want to use the use 5 second method as the scripts takes a very
 long time to complete.
 
 Is there something I am not aware of?
 What other method can I use? 
 Can I simply take a OS directory structure and import it into zope? I am
 not sure how.
 Can you point me some sample code or literature.
 
 Your help or guidance is much appreciated.

[Zope-dev] symbolic link patch

2002-02-18 Thread Maik Jablonski

hello,

i found this patch for creating symbolic links within zope:

http://lists.zope.org/pipermail/zope-dev/2001-August/012711.html

snip
- edited CopySupport.py
- copied the manage_pasteObjects method to a manage_pasteMonikers
method
- commented the #ob=ob._getCopy(self)  line  (the duplicate object part)
- added a Paste Ref button to the lib/python/OFS/dtml/main.dtml file that
calls the pasteMonikers method
/snip

it seems to be great for my purposes  works fine  i plan to use it on a production 
system.

has someone any information about problems with this kind of patching? something 
like breaking the database in long terms or even more ugly?

thank you,

Maik
