Hi,

I'd like to comment on this, and summarise some references below. Much of
this discussion took place on the zope-dev list (see references), so I'm
cc'ing the zope-dev list. You might also wish to add to the Wiki:

 Subject: [Zope] highly available Zope thread; our hanging problem
 
 Hi all -
 
 I was looking at the discussion from April that was posted on the
 HighlyAvailableZope Wiki about problems with Zope hanging; we had a
 similar situation here at Digital Garage which seemed to be alleviated
 by changing the zombie_timeout to be really short (like, 1 minute). 
 Before changing the zombie_timeout, the server would periodically hang
 and not give any responses to requests, sometimes recovering after a
 short time.

Some questions at this point:
1. Were you running with multiple threads, and if so, how many?

2. If you were using multiple threads, would *all* the threads periodically
hang, or was the hanging isolated to a single thread at a time?

3. Could you possibly comment on the operating system used?

4. Which zombie_timeout did you twiddle -- the one in the zhttp_channel in
ZServer.py, or that in http_channel in medusa/http_server.py?

 At this point, I don't have anything more than just an empirical
 observation - changing this parameter seemed to help our server.  Has
 anyone else noticed anything similar, or can explain this observation?

Concerning the zombie_timeout suggestion, here are some references when I
posed the question of whether reducing the value would be beneficial:

Amos Lattier wrote in
http://lists.zope.org/pipermail/zope-dev/2000-April/004194.html:

 connections, not zombie publishing threads. These are quite 
 different beasts.

Michel Pelletier wrote in 
http://lists.zope.org/pipermail/zope-dev/2000-April/004229.html:
 What the Zombie timeout means is that after a publishing thread gets
 done answering a request, the socket may not go away.  This many for a a
 number of reasons, the client 'hung' and is not 'putting down the phone
 after the converstation is over' (so to speak) or network troubles may
 prevent the connection from closing properly.  This means that there is
 a 'zombie' connection laying around.  This zombie will probably end up
 going away on its own, but if not, ZServer will kill it after a period
 of time.
 
 The only reasorce laying around during the life of a Zombie is an tiny
 little unused open socket, the Mack truck of a Zope thread that served
 the request for the zombie socket does not 'hang' for that entire period
 of time, but goes on after it has completed the request to serve other
 requests.
 
 Amos is correct in that these problems are almost always at the
 Application level, and not at the ZServer level.  The fact that Pavlos
 can prevent hanging by inserting a print statement in the asyncore loop[*]
 is suspicious, but we do not have enough information yet to point
 fingers anywhere.

[* references http://lists.zope.org/pipermail/zope/2000-April/023697.html]

I'd be _very_ interested in hearing more on this! Our Zope installation has
been pretty stable of late (isn't it strange that, when you want to find out
what's causing things to break, they play nice?), with uptime of
thirty-something days, but I'm still very keen to get to the bottom of this,
since I don't believe it was some ephemeral problem.

hth, and thanks again!

  Hi all -
  
  I was looking at the discussion from April that was posted on the
  HighlyAvailableZope Wiki about problems with Zope hanging; we had a
  similar situation here at Digital Garage which seemed to be alleviated
  by changing the zombie_timeout to be really short (like, 1 minute). 
  Before changing the zombie_timeout, the server would periodically hang
  and not give any responses to requests, sometimes recovering after a
  short time.
 
 Some questions at this point:
 1. Were you running with multiple threads, and if so, how many?
Yes; Zope is set to run with 16 threads (-t 16), and we've increased the
pool_size parameter in ZODB/DB.py to 16 also (guess this is all
right... :-P )

 
 2. If you were using multiple threads, would *all* the threads periodically
 hang, or was the hanging isolated to a single thread at a time?
All the threads hang.  One interesting thing is, we looked at vmstat and
whenever the system is having trouble, the number of system calls drops
dramatically, when the server is doing well it's normally up in the
1000s, but when it's in trouble there are like 20-30 system calls per
second, and they're all either lwp_* or poll s.

 
 3. Could you possibly comment on the operating system used?
Solaris, 2.6, on netras.  Our Zope is still v. 2.1.4.

 
 4. Which zombie_timeout did you twiddle -- the one in the zhttp_channel in
 ZServer.py, or that in http_channel in medusa/http_server.py?
The one in zhttp_channel.  As far as I can tell, since zhttp_channels
are actually used instead of http_channels, the number in zhttp_channel
is the one that matters.  The kill_zombies method, and the code that
calls it, is inherited from the medusa code... kill_zombies looks at the
timeout value of all the channels in the select list, and since all of
those instances happen to be zhttp_channels in the case of Zope, they
all use the zhttp_channel timeout.

 
  At this point, I don't have anything more than just an empirical
  observation - changing this parameter seemed to help our server.  Has
  anyone else noticed anything similar, or can explain this observation?

Yeah, I saw this... like I said, I haven't gathered enough information
yet to be able to say anything that sounds like an explanation; all I
have is a vague experimental observation.

I found out about the mpstat command on Solaris, didn't know about it
before, it gives you info on thread activity and multiprocessor
behavior, so maybe I can get some more info from that.

Hmm.

[Zope-dev] BerkeleyStorage.py is broken?

2000-06-06 Thread nw_moriarty

There are many admonitions to use BerkeleyStorage.py if you don't require versions in 
a database.  However, I have tried without success to get it to work with TCS.bsddb.db 
and BerkeleyDB 2.7.7 in a stand alone application.

How ANYBODY got it to work?

[Zope-dev] ReiserStorage 0.01 alpha

2000-06-06 Thread Petru Paler

  Hello all,

   Attached you can find the code for a preliminary ZODB storage manager
which is designed to take adventage of the reiserfs filesystem
(http://devlinux.com/namesys). While it is usable on other filesystems
too, the performance will decrease as the number of objects in your
database increases.
   Comments:

1. This is as alpha as it can be. While it is usable to do some testing on
a spare Zope, you must be insane to even try to use this on a production
system.
2. A generic DirectoryStorage is comming soon, with the diference being
splitting files by directory (and, of course, being slower than the
reiserfs version).
3. As you can see in the source, I/O errors in critical points can corrupt
the storage.
4. It currently does not support versioning and undo. I'm working first on
getting it stable and fast, and then add these features.

Feedback is not only welcome, but wanted :)

-Petru

I was kicking the idea of making one around, but I don't think I'll have
time to do it.

There's a document on how to write a Zope database adapter by Chris
Petrilli at:

http://www.zope.org/Members/petrilli/WritingADA

Since the Python layer has been (well) done by Alex, it shouldn't be too
hard to make one if you're OK with Python.

Good luck!

 I try out Zope last week and was greatly impressed with the

 my Company intranet to zope but I have one problem.  Our 
 company backend database servers (for items catelogs, leave

 check through all the mailing list and unable to find an

 Currently, I notice that Inprise has made Interbase an open

 coming out with an adapter on Interbase ?
 
 Or someone in the developing labs can give me guidelines on 
 how to write an adapter for Inprise Interbase on linux.  I 
 manage to get a copy python code that can access Interbase

 Thanks.

The Zope database is stored in var/Data.fs - that's most likely all you need
for a backup.  

If you want to have the same Zope install running on a different computer
and If you've installed Zope Products you'll also need to copy them from
lib/python/Products, and any External Methods you added from Extensions/.

Re: [Zope] Too many Roles?

  Is it crazy to have 20 or 30 roles in my Zope system? 

Nah.

Note that you need to create roles at a point in the tree, and they 
then appear and are usable on the management interfaces from that point
down.

I have to restrict access to resources by student subject or course.
I'm currently only using about 60, but its quite possible I'll quickly
end up in in the hundreds when more students start using Zope resources.
The trick is to only 'create' the role when you need to grant rights
to it. A role exists only in the point in the tree it is created and
down, and there is nothing to stop you creating the same role in
multiple locations. If you create them all in your root folder, your
security screens become useless, but it is fine if you only have
5-10 defined at any particular point.

I'm going to try to help out at the Debian booth as well.

How about I18N as a topic for one of the discussions ? I guess many European

Another topic I'm very interested in is packaging and distribution of Zope
extensions: keywords are Distutils, packages, zexp's, a package/dependency
tool like Debian's APT, distribution etc. pp., cf. Simon Michael's recent
rant about ZWiki/ZWikiWeb.

Looking forward to meet you,

Re: [Zope] www.mysite.com/Members/someone

2000-06-06 Thread Ian Sparks

Bill,

Thanks for the reply. Yes, I would be getting the data from a SQL statement.

Let me explain what I am trying to achieve.

I want to structure my site like this :

http://mysite.com/Members/username

so if someone comes to my site with the URL :

mysite.com/Members/Ian

They would see the Members page for "Ian" (we'll ignore permissions and
security for now).

As I have said before, one way of doing this is to have a Zope structure :

/Members
   /Ian
   /Jim
   /Jane

Where Members is a folder, Ian,Jim and Jane are Sub-folders of Members.

But I don't want to do this. What if I add a million users?  Then I end up
with a million member folders which is difficult to manage from Zope. I want
to store my users in a database.

I have no problem creating a DTML method which calls a SQLMethod passing a
parameter "username=Ian" to pull out the data and construct the HTML for
delivery.

The problem I have is how to construct my site. What I want is something
like :

/Members
   /*

Where * is a method which catches the rest of the url (/Ian) and does all
the necessary processing to return the formatted user page for Ian.

I know I'm missing the Zope Zen of this because it must be easy to do in
such a well thought-out product.

The thought I had was that "Members" could be a SQL method which takes
"username" as a parameter, Ian then is passed in as that Username and the
necessary data is pulled from the DB. This is fine except that I still need
some other method to render the HTML page for delivery to the user and this
would extend my url to : www.mysite.com/Members/Ian/rendermethod.

The other problem with this is that it clutters the root with the Members
SQLMethod and the rendermethod DTML document. I might start adding more
URL's like : www.mysite.com/Members/Ian/preferences or
www.mysite.com/Members/Ian/pastposts and the "preferences" and "pastposts"
documents would end up in the root too. All these things belong in a Members
folder, not at the root.

I'm missing something important, I'd appreciate any enlightenment you could
bring to this.

- Ian.

[Zope] Products, Factories, Permissions!!

2000-06-06 Thread Frances Keegan

I have a problem regarding permissions (I think).  I am using version 2.1.4.
I have a set-up like the one below:

STAFF_FOLDER_HOME   -   ONE named user with role as manager 
for this
entire folder and its contents.
(permitted to do all normal managerial 
 tasks).  Anonymous can
View, View  Contents Information, 
SearchZCatalogue  Use
Database Methods.

STAFF_MEMBER1_FOLDER-   As above
STAFF_MEMBER2_FOLDER-   As Above
STAFF_MEMBER3_FOLDER-   As Above


I have created a template using designer, builder etc., and have added this
to the AddList.  The template itself works ok; the problem is when the
template is used within these folders.

The manager of any of the above folders is able to choose the Instant Site
from the AddList, and fill in all the details in the form but when the form
is submitted it asks for your password again.  When you enter your password,
even though correct, it tells you that authorisation has failed and to try
again.  Eventually you are told that you are not authorised to
manage_changeProperties, even though these have been specified in the
Permissions tab as something the manager is allowed to do.

Please can anyone help - I have being going round in circles for what seems
like forever.

Thanks,
Frances

Re: [Zope] www.mysite.com/Members/someone

2000-06-06 Thread J. Atwood

Ian,

Make "Members"  a DTML Method and inside that method you call a ZSQL 
Method (made previously) that takes the parameter of 'userid=name'. 
Store the name of the member in the cookie and when the visit 
/members/ or /members/name it gets all the data from the SQL Database 
and publishes it any way you want.

Build any other functionality in the "Members" DTML Method to allow 
for /members/name/preferences or any other parameter you want to pass 
it. Just pick it up in an DTML-IF statement and do the rest.

Good luck.

Itamar The Zope database is stored in var/Data.fs - that's most likely
Itamar all you need for a backup.

If you store anything in the Gadfly database which comes with Zope you also
need ZOPE/var/gadfly .

If your application uses any external methods you also need
ZOPE/Extensions. 

If your application uses any products installed by you then you also need
ZOPE/lib/python/Products.

You both had the same problem I have now: make Oracle 8i (in my case, Oracle

DCOracle is working well (Makefile attached to this message) but ZOracle
isn't running yet.

We are posting e-mails about it on the list for a while and nobody answered,
so I must think that nobody on Zope universe is using Oracle 8i (neither NT
nor Linux Oracle 8i client).
There isn't any detailed documentation about it. The ZOracle installation
instructions are simple but, in my opinion, incomplete.

To solve this situation, I'm making a call to everybody that uses or wants
to use Zope with Oracle 8i. My goal is finally document the installation
process and make it work properly.

Please contact me ASAP.

[Zope] Re: Oracle 8i setup

2000-06-06 Thread Michal Bukovjan

Hey guys,

I am now lucky to get the Oracle 8i connection working. Here is what I did :

1) Download and install the latest Oracle 8.1.6 Release 2.
- the previous Oracle 8.0.5 and 8.1.5 are broken as hell, the executables will
not even link and there is a lot of unresolved symbols. I wonder on which
distro Oracle tested that, it will not work on Debian, definitely. Did not
expect Oracle to be such CRAP!!! 8.1.6R2 is much better.
- be sure not to want too much from Java wizards. They like to crash a lot, in
both 8.1.5 and 8.1.6

1.1) When asked to run a script root.sh as root, first check the script and
correct the path to awk. In script it thinks it is /bin/awk, on Debian it is
/usr/bin/awk. Other distros may vary. Run the script as root.

2) Download latest beta of DCOracle

3) Download and install the latest beta of ZOracleDA. Replace DCOracle included
in the product with the latest beta of DCOracle, which includes Setup-8.1.5 for
linking with Oracle 8i. It should build now according to instructions.

4) Install ZOracleDA as outlined in docs

4.5) Not sure about this, but hell, my setup now works. So you may try...
a) Put ORACLE_HOME, ORACLE_BASE, ORACLE_SID into /etc/profile, so
that everyone has these set up.
b) Symlink tnsnames.ora for
$ORACLE_HOME/product/8.1.6/network/admin to /etc/tnsnames.ora.
c) Double check file permissions on $ORACLE_HOME/*
d) Edit /etc/oratab as needed, start up the databases.

5) Restart Zope.

Now it works for me (Zope 2.1.4), and works for 2 days, did not try any heavy
loads, etc, though. At least it connects and I can browse inside the database.

It gave me some strange error like invalid connection string for some time, but
probably after performing something from 4.5, it now works well, Zope will not
freeze, and it works for two days now.

Hope this helps anyone, we spent three+ days getting this f*cking Oracle to
work :-(

[Zope] The ZPublisher :method type (was RE: [Zope] detail record editing))

2000-06-06 Thread Jeffrey Shell

 My solution for this kind of problem is to have a DTML method 
 that delegates
 to the
 appropriate DTML methods. Therefore each button gets a value 
 and a name, eg.
 input type=submit name=action value=delete
 input type=submit name=action value=modify

Actually, you can use the Bobo ":method" type.  It's
documented...somewhere :).

You can do:

input type="submit" name="mthDelete:method" value="delete"
input type="submit" name="mthModify:method" value="modify"

and the Publisher will add the selected method to the end of the path.
Make your form action be dtml-URL1; or "./"

There's a default_method type too, I think you *might* see it in action
on the "Rename" form in the Zope management screens.

[Zope] deleting objects

2000-06-06 Thread Webmaster

Sorry if this one is obvious.

I created a dtml method named "dev_header" in my site root. In another
folder further down my tree I created another "dev_header" with different
info. I then deleted the second "dev_header"  (/news/dev_header) expecting
my pages to then grab the "dev_header" from the root directory, but they
don't. Why?

How about I18N as a topic for one of the discussions ? I guess many European
sites and developers struggle with problems of I18N.

Another topic I'm very interested in is packaging and distribution of Zope
extensions: keywords are Distutils, packages, zexp's, a package/dependency
tool like Debian's APT, distribution etc. pp., cf. Simon Michael's recent
rant about ZWiki/ZWikiWeb.

Please check http://www.zope.org/Members/Linuxtag. Simon Cole may come and 
talk about ZWiki. They are not 100% sure yet.

Would you be willing to give a talk on I18N? Or one of your developers? I 
don't know what I am going to talk about, so I can talk a little about 
packaging. Are the Distutils really necessary. Zope handles that inside. If 
you update the .py files, it updates all the object's instances respectively.

 Can you help me ?

 I have some dates in a DataBase but I receive them in string after a query
 and it's in international format, I would like transform it in french
 format.
 With dtml-var date fmt=%d%m%y, it doesn't work.

 Do you know how can I transform it with strings:

 I receive : 2000-04-13
 I want  : 13-04-2000
 or:  13 april 2000 (this one is better but ???)


There's More than One Way to Do It :)


If date is a DateTime object you have to use:

dtml-var date fmt="%d-%m-%Y"
06-06-2000
or
dtml-var date fmt="%d-%b-%Y"
06-Jun-2000

or
dtml-var date fmt="%d-%B-%Y"
06-June-2000
See python doc ,  module "time",function "strftime "


If date is NOT a DateTime object (is a string like '2000-06-06') you have to
use:
dtml-var "'%s-%s-%s' %(date[8:10],date[5:7],date[0:4])"
06-06-2000

I saved this answer, because I thought I might need it -- might be what you
need:

==
From: "Eric L. Walstad" [EMAIL PROTECTED]To: [EMAIL PROTECTED]
Cc: [EMAIL PROTECTED]


I think I've got the syntax, Jeff:

dtml-var "_.DateTime(birthday)" fmt=aCommon

- birthday is a field returned from my Z SQL Method
- The "_.DateTime(birthday)" part creates a DateTime object
- The '_' is a reference to the DTML namespace
- The DateTime() function creates the DateTime object
- The fmt=aCommon part formats it to look like: "May 7, 1966 12:00 am"

You can change the format by changing the fmt= so that  is the
format you want from Appdx A of the Zope DTML reference.

Eric.

If the you the current time, you might also try using  ZopeTime instead of
"_.DateTime(birthday)".  

have fun!

[Zope] ZOracleDA binary for NT?

2000-06-06 Thread Satheesh Babu

Hi folks,

I've been trying to access a Oracle DB with
ODBC driver from NT4 running Zope 2.1.6. 

Lot of problems and now I'm stumped in that this
driver does not seem to support LONG data types.

ZOracleDA on Linux works beautifully, but
I'm required to build the site on NT (sigh).

So, any one out there has a precompiled ZOracleDA
for NT, which he/she doesn't mind sharing with me?

Or, any hints on using LONG datatypes with ZODBC driver?

Thanks in advance.

 dtml-var title_or_id will give you the title or id of the object

 you want.
 
 Well, that don't work either. And if I am correct; dtml-var

Yes, that is correct.  I think what you want is dtml-var

[Zope] WorldPilot - Regular messages are attachments?

2000-06-06 Thread Bryan Stillwell

I'm posting this message to the Zope mailing list, because I haven't had
much luck with emailing the WorldPilot folks directly and I've seen posts
about WorldPilot in the list archives.

Here's my problem.  I've created an rpm of WorldPilot that follows all the
instructions that are in the INSTALL.txt file that comes with it, I've
installed courier-imap and tested that it works correctly with Netscape
Mail, I've installed qmail and tested that I can send and receive email,
but the problem I have is when I try and view messages in my inbox using
WorldPilot.

If you want to know what I see, here's some screen shots of what happens:

http://www.verinet.com/~arcane/worldpilot/wp_inbox.png
http://www.verinet.com/~arcane/worldpilot/wp_message.png
http://www.verinet.com/~arcane/worldpilot/wp_zopeerror.png

Here's the traceback I received:

Also I want to bring to attention that in the wp_inbox.png picture that I
don't have any folders to choose from.  Does anyone know where those would
be at?

Another strange thing is the path to the mimetools.py file in the
traceback: /var/tmp/python/python-root/usr/lib/python1.5/.  The
/var/tmp/python/python-root path should have only been used during the
creation of the python rpm, but it's showing up now.  It doesn't seem to
matter that much though, because it is able to find mimetools.py at the
correct path of /usr/lib/python1.5/mimetools.py.  The python-root
directory doesn't exist either.  I didn't recompile the python rpm either,
it's the stock rpm that comes with Redhat 6.2.


My setup is as follows:

Redhat   6.1
qmail1.03+patches-8j (Set up to use Maildirs)
courier-imap 0.33-1 (IMAP program that supports qmail's Maildir format)
python   1.5.2-13
Zope 2.1.6-1
worldpilot   1.0.4-1 (Installed with my own rpm)


Thanks for any help any one can provide in advance!  Hopefully I can get
these problems resolved and I could then post the rpm for others to use.

Re: [Zope] GadFly DB and Zope

2000-06-06 Thread Dieter Maurer

Hi Jilani

  I am recently using the database GadFly and yesterday, I discovered with
  pleasure that it is part of Zope (ZGadflyDA); so, I will be happy if
  somebody tells me with a little example, or point me where to find some
  information to get GadFly interact with it Zope (just how to call field1
  and field2 from the database test.gfd).
  
  Thank you.
Zope looks for directories in "var/gadfly" as possible data sources
for Gadfly.

You can use it like any other DA -- see the ZSQL Methods User Guide
for details.

At least an earlier version of Gadfly was cribbled in Zope (2.1.0).
It did not write changes to disk, such that each Zope restart
removed any changes to the Gadfly database.

I may still find the patch I made for this. However, I am not sure,
whether it is still necessary and whether it still can be applied
without problems.

[Zope] trouble with acquisition

2000-06-06 Thread Erik Myllymaki

Hello,

I am new to OOP and Zope so please forgive me if I am being a chowderhead
;-)

I have a root report folder called "ReportParent". Within this folder, I
have 47 folders called, for simplicity, "report1, report2 ... reportN".
Within each of these folders I have a ZSQL query called "query" that is a
simple select statement.

In the ReportParent folder, I have an external method called columnNames:

#---
def columnNames(self):
""" docstring """
fieldnames = []
tempList = []
res=self.query()
columns = res._schema.items()
for (name,value) in columns:
 tempList.append((value,name))
tempList.sort()
for name, value in tempList:
 fieldnames.append(value)
return fieldnames
-

This returns the column names of the batch returned by the "query" ZSQL
Method in each reports1..N folder. In each folder is also an "index_html"
DTML Doc that renders the batch returned from the ZSQL Method:

-
dtml-var standard_html_header
Created for dtml-var "REQUEST.AUTHENTICATED_USER.getUserName()" on
dtml-var ZopeTime fmt="%d/%m/%Y" at dtml-var ZopeTime fmt="%H:%M" br
p
table border="2"
  tr
  dtml-in columnNames
   dtml-comment Click on column header to re-order by that
column!/dtml-comment
tda href="dtml-var URL1?orderby=dtml-var sequence-item"dtml-var
sequence-item/a/td
  /dtml-in
  /tr
  dtml-in query
  tr
 dtml-in sequence-item
 td align=rightdtml-var sequence-item/td
 /dtml-in
  /tr
/dtml-in
/table
/p
dtml-if "REQUEST.AUTHENTICATED_USER.getUserName() == 'root'"
hr
p
SQL Source:brpre
dtml-var expr="_.string.replace(query(src__=1),_.chr(0) ,'hr')"
/pre/p
/dtml-if
dtml-var standard_html_footer


I can call these queries with - www.mysite.net:8080/ReportParent/reportN and
get the desired results.

I have two questions on how I would like to change things:

1. The DTML Doc "index_html" is the same in the case of 45 of the 47 reports
folders. Seems to me I should be able to move the common index_html up to
the ReportParent folder, and just leave the two specialized ones where they
are, in their report? folders and continue to call the reports the same way.
Those that have a local index_html will use that, the others will look up
the hierarchy and find the common one in ReportParent. However, when I do
this and call the reports with the same URL I get:
"Error Type: AttributeError - Error Value: query" ?
Seems the index_html DTML Doc (or columnNames extended Method) can't find
"query" below it. How do I address this properly?

2. How do I pass in the ZSQL Method object to the external method
"columnNames.py"?
I'd like to name the queries what I want and reuse this method anywhere,
without the query having to be named "query". Out of frustration, I named
all the queries with the same name and then addressed "query" explicitly in
the external method, because no matter what I tried, I couldn't get the
cloumnNames methos to accept the ZSQL Method name as a second parameter?!

Thanks for your input,

Erik Myllymaki

[Zope] Deleting folders from root

2000-06-06 Thread Josh Glover
When I try to delete a folder from the root of Zope, it does not allow
me to do so.  No error message, just displays the index_html method in
my browser window.  Same story if I attempt to rename them.  Any ideas?

You can have as many action="submit"'s as you want.

Untested:

input type="submit" name="add" value="1"
input type="submit" name="modify" value="1"
input type="submit" name="delete" value="1"

The form only submits the value of "successfull" form items, so, on your
form's action method:


dtml-if add
  do your adding thing
dtml-else
  dtml-if modify
do your modifying thing
  dtml-else

[Zope] Mozilla problem

2000-06-06 Thread Timothy Grant

Hi,

I've recently started experimenting with Mozilla M16. While my pages
seem to work beautifully, I can't get into any of the management
screens. When I add /manage to the URL, I get nothing, no authentication
box no error, nothing.

Am I missing something, or is Mozilla missing something?

Pete,

This doesn't really fix the underlying problem, but if you'd like to carry
on working with Zope you can rename the file zopedir/var/Data.fs and Zope
will recreate a new (good) Data.fs for you.

[Zope] sort_order???

2000-06-06 Thread michael angelo ruberto

hello,

ok, here is my code:

dtml-in table-1 sort=date

a href="dtml-var URL"dtml-var name/a | dtml-var value | dtml-var
URL | dtml-var attendee | dtml-var datebr
/dtml-in

what's wrong - nothing, it works fine. however, the result is sorted by date
ascending and i need it to be reversed. i found a reference to an attribute
"sort_order" which can be given an arg such as "sort_order=reverse". the
problem here is that it won't work and i can't find any usage info on
"sort_order". it isn't mentioned in the DTML Reference and after hours of
searching the Zope website i am empty handed. does anyone know how to use
this? thanks in advance.

-mike-

[Zope] Confera and strict permissions

2000-06-06 Thread Cary O'Brien

I'm trying to set up a small site with a Confera topic (using Zope
2.1.6).  It is going to be accessed by some off-site co-workers
through the internet, so I am concerned about security.  Access is
through Apache on the firewall with some mod_rewrite address filters,
but I'm kind of a belt-and-braces guy when it comes to security, so I
only want people who have user entries and passwords to access the
discussion.  No anonymous access at all.

But, if I remove the default "Anonymous" access privileges granted in
the root folder, even users with user entries who can access other
documents get access denied when trying to view the Confera topic.

This happens for both remote and local access.

The error traceback seems to point to a problem with the tree tag
rendering components.

Any ideas?

You both had the same problem I have now: make Oracle 8i (in my case, Oracle

DCOracle is working well (Makefile attached to this message) but ZOracle

We are posting e-mails about it on the list for a while and nobody answered,
so I must think that nobody on Zope universe is using Oracle 8i (neither NT

There isn't any detailed documentation about it. The ZOracle installation
instructions are simple but, in my opinion, incomplete.

To solve this situation, I'm making a call to everybody that uses or wants
to use Zope with Oracle 8i. My goal is finally document the installation
process and make it work properly.

Please contact me ASAP.

Hello Alexandre. We intend to use Oracle 8i (8.1.5) with Zope (on another

 Can anyone give me more info on this? I missed any reference to

 various archives. I have just such a problem and I hope

The problem was related to Netscape browsers on Win32 sending
If-Modified-Since headers with dates like "15-Mar-00" when they meant
"15-Mar-2000". This caused two problems in Zope.

The DateTime module reinterpreted the date as "15-Mar-1900". This has been
fixed in the CVS version of the module where years of the form 00-69 are now
interpreted as 2000 + 00-69.

The second problem ocurred in OFS/Image.py where the date was turned into
whole seconds with Python's int() function. Dates so early lead to float
numbers that exceed the range of numbers int() can deal with. This is also
fixed in the current CVS version.
