RE: [Zope] KM|net News help

[Wesley Anderson]

Thanks for the reply, Kevin.

Just to clarify, once I have SMTP access, I can add older articles to the
KMStore via the "article editing page"? It's just not possible via the
management interface. Also there is no way as of this version, to remove the
Author and Date/Time tags?

Another question: when you're on byproducts.com, you're able to link to
articles like this:
http://www.byproducts.com/art/2000/6/961509971/ what I'm finding is that
when I link like this on my site, I just get a blank page - I have to add
index.html in order for anything to show. Is it just me or is there
something I have to do?

Thanks again


Wes

I seem to be saying this a lot lately so apologies for the copy to the

Squishdot does not currently work with Zope 2.2

It WILL NOT work with Zope 2.2 until about version 0.4.4 of Squishdot.

It will work with Zope 2.1.6 and earlier.

Thankyou,

I'd prefer to see a generic way of escaping structured text formatting.

Maybe this is something for StructuredTextNG?

Would this whole problem go away if Zope had a 'backup data.fs' funcion

That probably means you are using ZODB2, yes? (please say yes; ZODB3
should be immune to this problem). If so, there used to be a tool to
correct the timestamps... you should be able to find it in the utils
directory in the Zope 1 CVS

It would, but keeping it in memory would be a bad thing.  Say your data.fs
file was 10GB large, and it took 4 hours to back it up, and you only had
X amount of RAM - then it would begin swapping after some time.  Now that
would be ugly :-).

One could possibly have a function that put new transactions in a new
file, and then - when told it was ok to do so - it could update the
regular data.fs file.  

Actually, if I'm not mistaken, this could be something to put in ZEO?

Hmm, about extending this so you have 'rotating data.fs files' in the
same way you have rotating log files?

Definitely, but I think it also needs to be solved for the normal Zope

Then it'll be missing if something tries to get it from a rack. The same
thing as would happen if something tried to get it from a single rack
after it'd been deleted. So this case should be covered anywhere as it's
essentially 'what happens if an object that doesn't exist is requested
from a rack?'

That said, can you give em an example where it would eb useful to have
one object stored in multiple racks?

[Zope] Re: Zope won't let me call aq_parent in ZWiki?

Hi Curtis,

Sorry for the late reply, I've been on holiday :S

This is a 'feature' of ZWiki according to Simon Michael, it's author, I
think it's a bug ;-)

Basically, ZWiki Pages (RecentChanges is a ZWiki Page) execute DTML
contained in themselves with the 'Anonymous' role, supposedly as a
security precaution.
This means that 'Anonymous' must have the 'Access Contents Information'
permission for RecentChanges and several other things to work.

This makes it practically impossible to have a Wiki that is secure :/

This is a hard problem to solve, see Jim Fulton's server side trojan
stuff for a detailed discussion. I don't like the current solution, it's
confusing.
A better, but not best ;-), solution would be to make ZWiki pages
execute with any proxy roles they have and only those roles, or even
have a seperate 'This Wiki Page has these roles' configuration box.

A workaround would be to make RecentChanges a DTML method rather than a
ZWiki page. You should just be able to copy and paste the contents.

HTH,

Chris

This would be a solution... 
The problem is to split the design/program from the content I think.
AFAIK xml supports multiple languages in one file - perhaps we should

How do you do to cache those objects, since LocalFS

  Ding ding ding. Found it. Just what I was looking for! I'll give it a

build on.  What I did not find about LaTeX was a screenshot (isn't it
a wysiwg enviroment on top of TeX marked-up text) and a content link
to zope - this might be done, however, through the DocBook DTD and the
XML stuff in zope. Which leads me to the later suggestion, I have
tried out DocBook product, rendering is very slow on my computer.
And again it is too big of a new concept for me now.

I have looked into the YihawDirectory product a little deeper now, it
fits very well into my idea to connect the content with the
references closely. A lot of my code methods I produced in order to
tweak a good reference handling is not needed any more, what is left
are a few headers and footers implemented as methods, for design and
navigation purposes, and folders having chapter properties and
containing documents for holding content. 

I still want to look into XML and DocBook, though, xml could be
easier to manage as the work grows.

On first glance, for xml I found  an interesting (but somehow
abandoned) software  named conglomerate http//www.conglomerate.org/,
another is Xeena of IBM. The GUI of both (especially the former) seem
to have nice XML editing capabilities.

[Zope] Getting at Zope (Version) Transactions

[Darin Lee]

Hail Zopistas, 

I would like to develop a "what's new" method that parses/accesses the undo 
transactions list for certain documents so I can post basic information about when 
they were added, updated etc. in a DTML method for display on my index page. This 
would also come in very handy for a file-archive system I am planning on building. 
(I'm talking about the info that shows up when you hit the "undo" link in Zope 
manager).

Is there a way to get at the transaction data? Is this data stored after a version is 
merged back into the main ZOBD? What would be the best way in Zope to parse this log 
for certain types, and generate a DTML method? Does Zope support Regular Expressions?

I hail from the Perl coders guild (where generating and parsing text/sql is a 
relatively easy, albeit messy, task) - but am new to Python and OOP in general. 
However, now that I have Zoped, I can see there's no turning back.

Any help would be greatly appreciated!

No. LaTeX is, simply phrased, a collection of macros and templates
for the TeX system. They include a lot of professional typesetting
and design know-how which is applied dynamically to the document,
so the author of the paper can concentrate on the content, rather
than on the layout. You can still give explicit layout commands,
if you know what you're doing. (Most people imho don't.) 
 
LyX is a document processor for Unix and Win32 building on the
LaTeX/TeX engine which uses a wysiwym approach. It's worth one
or two looks:

Yes, there are screenshots =:->

You could use any of the tools on

and then import the exported HTML and PDF documents to your
Zope installations to avoid the speed penalty.

Hi Jeff - 

Thanks for reporting this. It turns out that there was a 
missing security assertion in the product dispatcher 
(manage_addProduct) that was causing this. The fix will 
be in b4. If you want to patch your install in the meantime,
edit lib/python/App/FactoryDispatcher.py and change:


class ProductDispatcher(Acquisition.Implicit):
" "

def __getitem__(self, name):
...

to:

class ProductDispatcher(Acquisition.Implicit):
" "

# Allow access to factory dispatchers
__allow_access_to_unprotected_subobjects__=1

def __getitem__(self, name):
...

Re: [Zope] Multiple Languages

[Dan Rusch]

I posted a similar question here a few days ago, subject line
Internationalization. The responses were less than overwhelming and
although I greatly appreciated the suggestions from the people who did
respond it was quite apparent that the problem of multilingual sites has
not been solved gracefully yet.

The best idea we came up with so far, which was also one of the
suggestions, is to either let the user select a language or more
preferably examine the HTTP_ACCEPT_LANGUAGE variable in the REQUEST
space.

based on it's setting we change a property of the top level folder:


 

 



which as you can see adjusts the acquisition path to traverse through a
language specific folder.

Next on each page instead of text we use dtml methods that hold text:



  .







Notice there isn't any plain text on the page, but that the text to be
render is in the variables someText and moreText. I would suggest using
variable names that are made up from the text to be displayed (in the
native language of the developer). For example say the text to be
displayed is: "Customer Contact Information" the variable name maybe
. Prepending the 't' tells me that this is a
text holder.

Lastly in the folder English and Italian, in this example, we have
placed dtml methods someText and moreText with the appropriate
translations in them.

The correct language is rendered automagically based on the user
choice


we preferred this to the alternative of placing the translations in the
page because to add another language, say German, when the translations
are on each page ,would require touching every page in the site. since
we have close to a thousand pages, we found this to be unacceptable. In
the system I have outlined above all that would be required would be to
copy the english folder to a german folder and translate each method
into german and poof you have added another language


hope this helps ,
DR

I've got it going using direct invocation of z2.py, but I'm having
problems running it as a service. I think maybe the python version is
slightly more advanced 1.5.2+ than the one which PythonService is using.
Perhaps there's a dll clash.

[Zope] bobobase_modification_time off by 1 day - why?

[Luke Tymowski]

Hello,

Zope reports the bobobase_modification_time  to be off by one day (1 day 
behind). The box has the right time (when checked from the OS), and asking 
Zope to return ZopeTime returns the correct date and time.

Anyone know why?

[Zope] DCOracle Problem

[David A Lipsky]

I was wondering if you could help me with a problem I've been having
with DCOrale, connecting to Oracle8i.
 
 
  import DCOracle

  conn = DCOracle.Connect(...)

  curs = conn.cursor()
  conn.procedures.some_stored_procedure(curs)
  curs.fetchall()

  curs = conn.cursor()
  conn.procedures.some_other_stored_procedure(curs)
  curs.fetchall()


some_stored_procedure and some_other_stored_procedure
return different rowtypes.

Either the second call throws the following error, or
it returns the wrong set of columns (it will return only
those columns that were returned in the first call):


  Traceback (innermost last):
File "", line 1, in ?
File "/usr/lib/python1.5/DCOracle/ociProc.py", line 134, in __call__
  for c in iocursors: c._describe()
File "/usr/lib/python1.5/DCOracle/ociCurs.py", line 130, in _describe
  if rc!=1007: self._error()
File "/usr/lib/python1.5/DCOracle/ociCurs.py", line 109, in _error
  raise error, (rc, oci_.OracleErrorMessage(self._c.lda, rc))
  oci.error: (1003, 'ORA-01003: no statement parsed')


Explicitly closing the cursor between the calls doesn't seem to help,
nor does reusing the same cursor.  The only way I've been able to call
two stored procedures in this way is by closing the connection itself
between calls.


Here's an actual session:


Note that get_sentence_ids should return one integer per row,
and get_sentences should return that integer along with some
text.

>>> import DCOracle

>>> conn = DCOracle.Connect('/')

>>> curs = conn.cursor()
>>> conn.procedures.get_sentence_ids(curs)
>>> curs.fetchall()
[(6,), (5,), (8,)]

>>> conn.procedures.get_sentences(curs)
>>> curs.fetchall()
[(6,), (5,), (8,)]

>>> curs = conn.cursor()
>>> conn.procedures.get_sentences(curs)
Traceback (innermost last):
  File "", line 1, in ?
  File "/usr/lib/python1.5/DCOracle/ociProc.py", line 134, in __call__

raise error, (rc, oci_.OracleErrorMessage(self._c.lda, rc))

Any advice or help you can give would be greatly appreciated.  Thanks!

[Zope] Authentication, Anonymous and Public

[Capesius, Alan]

Title: Authentication, Anonymous and Public





I'm running into a problem after implementing jcNTUserFolder in a 
subfolder of my site. Users can access the root level or particular 
subfolders anonymously. Once a user accesses the protected 
NTUserFolder, the credentials are saved in the browser. If the user 
then returns to the anonymous area, they can no longer access th 
folder due to the browser credentials.


Does Zope have a mechanism equivalent to the Novell NDS Public access?
that is to say:


Anonymous = not authenticated.
Everyone = authenticated users (that are members of the group)
Public = authenticated and anonymous users.


I'd like the default access to be "anybody and their brother" rather 
than "those people who haven't logged in"

[Zope] NOTICE: issue with database packing in current Zope releases

[Brian Lloyd]

Hi all,

Jim found a problem with the algorithm for packing the Zope
database that we wanted to announce so that folks can avoid 
being bitten by it until the fix is out (in b4).

The gist of it is that you should not pack your database to 
a given time and then subsequently  pack the database to an 
*earlier* time. For example, do not pack to "older than 0 days"
and then pack to "older than 10 days". The algorithm in the 
current Zope releases doesn't handle this correctly and 
depending on the exact circumstances can end up getting rid 
of objects that it shouldn't in the packed version of the 
database.

Note that if you _are_ inadvertantly bitten by this, you can 
recover by using the Data.fs.old in the /var directory that is 
created at pack time.

Toby, 

(sorry not to get back to you earlier on this) 

The security assertion is generally tested on instances, so if 
an instance has the assertion in its class (or any of its base 
classes) then it is effective for all of the base classes of 
that object.


> Secondly, I am confused that there have not been any security 
> changes in ObjectManager.py and PropertyManager.py. As I 
> understand it, the subobjects that they manage (ie properties

> category. What am I missing?

Actually there has been a change: the security assertion is in 
SimpleItem.Item (which acts as a base class for most, but not 
all, Zope objects). This is why "dynamic" attributes such as 
properties continue to work as before.

Your first reaction might be (as mine was) "well, doesn't that 
just put us right back where we were before?". Not quite. What 
has been done is a first step to changing the policy to deny-
by-default rather than allow-by-default. Having the assertion 
in the Item class has the effect of:

  o allowing access to properties and some other kinds of 
attributes that are not currently explicitly protected, 
needed for backward compatibility

  o DISallowing access to certain other things that the old 
security rules would have allowed - for example under the 
old rules alone it was possible to get to the func_globals and 
other attributes of methods that you really shouldn't have 
access to. We had to handle that with special cases, which 
was painful and error prone (and only worked for problems that 
you knew about). 

The new policy with the security assertion allows us to keep access 
to properties and things we _need_ access to for backward 
compatibility, but also has the effect of protecting things like 
method attributes and other (possibly unknown) bits that should be 
off limits (a method would need a security assertion of its own for
those things to be accessible). 

While this is not totally perfect and still requires you to be 
careful about protecting attributes of base classes, it is better 
than it was before and a first step on the road to where we want 
to be that shouldn't cause too much angst among users and product 
developers.

Hope this helps - I'm going to reformat this a little and add 
it to the Product author guide.

[Zope] DTML Document class Id bug, somewhat fixed. But now setName ...

[Walter A. Aprile]

Hi,
I had (have) a problem with the Id property on an Article class that
subclasses the DTML document.

And indeed the problem was with the fact that I was subclassing the
DTML Document, which as explained in http://www.zope.org/Members/AlexR/ZClassIDBug
somewhat mangles the Id property. Public thanks to Rik Hoekstra 
<[EMAIL PROTECTED]>
for suggesting that. 
I added this fix (from the page I mention above) to the constructor method,





And when I try creating a new object, it blows up in my face with this
error:

Unauthorized

  You are not authorized to access setName. 

  Traceback (innermost last):

I _think_ that my user on this system has enough permissions to do this. Should I 
just ditch the class and recreate it (under the hypothesis that I botched something
while I was creating it the first time), or should I pester the guy that made my
user for additional, God-like, power ? And what is so special about setName ?

This is under:

Having used latex for a long time I would like to point out that if you
are planing to to write many papers for conferences/publications Latex has
some very helpful tools. For one many scientific journals provide Latex
style files so you don't need to worry about formating. Also (and IMO the
most important) are the pain in the ... bib contents. There are very nice
bib databases for Latex and latex (or bibtex) can produce bibliography
contents in the formats required by most journals. Check also Lynx which
is a minimal (last i checked) wysiwig environment for Latex.

[Zope] WebOS and Zope

[Jason Spisak]

Zopists,

I have been away for a bit, and will be gone again soon, but I found
this the other day:
Has anyone checked out http://www.webos.com  ?
It's free to sign up, just use explorer 5.0 and try it.
I was amazed. It has drag and drop, looks like a real desktop.

Now for the Zope angle:

I am curious if anyone thinks Zope can server up content like this?  XML
Desktop?
I think they are using ColdFusion though.  An actual webtop powered by
Zope.
What would it take?

They say they are going to release it OpenSource on their developer
page. ;)

All my best,

RE: [Zope] Backing Up Zope (was: Re: [Zope] Data.fs.lock?)

[Wilkinson Charlie E]

Title: RE: [Zope] Backing Up Zope (was: Re: [Zope] Data.fs.lock?)





Just to start by pointing out the bloody obvious:


- Restoring from backup means you lose all data between
  backup date/time and system failure.  Sucks, but it
  beats losing *all* your data.  (RAID5 anyone?)
- With that in mind, *consistency* of the backup database
  takes the highest priority.  All existing transactions
  should be fully completed - no half-done updates, etc.


It seems to me that the easiest way to get there with ZODB
might be to just make a simple file copy of the database and
have some kind of integrity checking tool to run against the
static backup copy to weed out the junk.  Is this possible,
does it already exist?


Probably a dumb question, but would Zope itself do this if
you fired it off against an inconsistent ZODB?


Another random thought is that if ZODB transactions and
writes are atomic, than none of this should be an issue.
Anyone know the answer to that one?

They aren't cached. I experimented with adding a cache, but ran into some
problems and gave up. It would probably be worth giving it another shot, though.

Walter -

this is sort of a tricky one :(  The problem is that the 
ZClass id bug is a legitimate bug (fixed in the 2.2 series), 
but your fix uses a method that should never have been 
accessible in the first place (and in fact the hotfix makes
it inaccessible, as it should have been all along).

So there are two things you could do here to get along until
you can upgrade to 2.2. One, you could edit the __init__.py
in the Hotfix product's directory and comment out the line:

DocumentTemplate.DT_String.String.setName__roles__=[]

...and restart Zope. That will make the setName method 
unprotected again though, so don't do this lightly. By 
unprotected I mean that other people could call setName 
on _your_ objects and screw things up if they wanted to.

An alternative would be to create an external method like
the following in your class:

def temporary_hack(self, id):
  self._setId(id)


...and try using:

  
  
  


That should let you solve it without reopening a security hole.

Hope this helps!

[Zope] Getting Zope error when starting Zope, installed on ISP's machine

[Fusion Group]

I installed Zope on my ISP's virtual server, and I'm getting an error when I
run the start script.  The server is running Apache, but I don't really need
to use Apache for this particular domain.  I haven't tried to figure out how
to access Zope through PCGI, because unless that is the only way to allow
Zope and Apache to run on the same machine, this isn't necessary.  I have
Zope and Apache successfully running on my own development machine (SuSe
Linux), but my problem is running it on a virtual server (FreeBSD). Below is
the error message I get. Any help would be greatly appreciated.

Re: [Zope] How to update DTML built from Python level?

Well, I edited the file I mention below (documentEdit.dtml) and

(Reason: if Mozilla sees  inside a ,
the text inside the textarea is centered in the textarea, which

Thanks for the bug report. I can easily fix the "order" issue, but I am
so far unable to reproduce the JavaScript error.

Can you give me more information about your platform, the error message
and what steps you took to achieve the error? If you do things
differently (like create an instance of the tutorial with the product
add list) does the tutorial work?

Thanks!

[Zope] Adding DTML Templates to ZClass instances

[Eron Lloyd]

I would like to have an option when creating an instance of a folderish
object to have a "index_html" template automatically added to the new
object once it is created. I have the template for the inserted
index_html sitting in my root directory of Zope. How can I tell the
constructor method to add this template as a DTML Method (template_dtml)
to the just created instance and rename it to "index_html"? This I
cannot find documented anywhere. What I'm trying to do is practically
identical to the option available when adding a standard DTML
Document/Method from the management interface.

Thanks in advance,

Eron

It is my understanding that the ZODB on disk is always in a consistent
state; Jim has said, in the past, that you can simply make a copy of
Data.fs, even while Zope is running, without problems.

Based on that, I think the answer to the above is yes.

[Zope] File upload failure. Help needed.

[Urvashi Singh]

Hi,

I am a new user of Zope. I have Zope--linux2-x86.tar.gz bundle installed
on my Linux machine, up and working. While I was trying to create a simple
page using dtml files, I wanted to upload a few files from my hard drive 
onto Zope database. When I choose the Browse button to select a file from
the targeted directory and say "Add", I get an error message:

   "The document contacined no data.
Try again later, or contact the server's administrator."

I fail to understand, why am I getting this error when the targeted file 
size is 25519 bytes ?

Kindly advice.

Also kindly suggest which document to go through before writing Zope
applications.

Thanks and Regards,
Urvashi

[Zope] queries and tiny tables and python methods... oh my!

[Timothy Wilson]

Hi everyone,

(Please excuse the vague Wizard of Oz reference in the sub., but my brain
may be imploding. :-)

I'm trying to merge several type of Zope objects, and I'm getting lots of
little errors. I wonder if someone could suggest where my problem lies.

1. I'm querying our LDAP server to retrieve the records for a given person
in the directory. No problem there.

2. I'm parsing one of the entries in the LDAP directory to retrieve the
user's location. Python method code is simple.

3. I'm using a Tiny Table to look up a value for one of the parsed strings.
Easy.

The problem is hooking them all together. Passing the query to a
PythonMethod is throwing up the following error:

Error Type: TypeError
Error Value: argument l: expected read-only character buffer, instance found

(BTW, Netscape on Windows doesn't product a traceback, but Netscape on Linux
does.)



parseLocation is a Python Method which takes 1 argument (a string) and 
returns the first element of the list that's formed by splitting the string.
That first element is a two-letter code that's looked up in a Tiny Table
called buildingCodes which returns the full name of the building.

OK, it looks to my relatively inexperienced eyes that the Python Method
isn't getting an argument of the type is expects.

Here's the code for parseLocation ('l' is the argument):

x = string.split(l, '_')
return x[0]

(BTW, changing it to x = string.split(`l`, '_') eliminates the error, but
nothing is rendered.

qry_person is an ZLDAP filter method that takes one argument (uid). The
original dtml to display this mess looks like:



  
  # 'building' comes from the Tiny Table
  


I'd appreciate it if anyone has any ideas about this. I'm probably making
the whole thing too complicated, but for reasons of code reuse, this seemed
like the most efficient approach.

But the Data.fs has to be updated sometimes.  And if you read from a file
that is changing, the integrity of your data isn't.  How can you make sure
that the file is not written to during a certain period of time?  You
can't?

A) Please: no html!
B) I just had one weird and wild thought. A RAID5 type of storage using
ZODBs instead of blocl devices. Probably not doable, and might not gain
anything if doable, but it was one of those ideas that shoots across
your brain and sounds cool at first. Just thought I'd share.

Now that I'm in the spotlight I can't seem to find the message I was
referring to in the archives; I sure hope I didn't misquote anyone (i.e.
Jim).

Unfortunately, I don't have an answer to your question. I still believe I
am correct, but cannot tell you, technically, why. I have some theories,
but I don't want to cloud the issue anymore with my hypotheses.

Let's hope someone who does know chimes in.

Since mine happens only on certain pages (forms), perhaps I should just
build up a list of bad remote IP addresses ( criteria - generates more
than 5 errors on the same page ), and then redirect those clients to
another non form page with indexing information for my site... sounds
like the basis of a product

[Zope] [lines] element in "property sheets" ++ \345 29 \345r ..

[Jørgen Skogstad]

Kindest.. 

I have object contained in ZObjects .. and I have some object
"parsing" the contents based on a search.. The type in the 
property sheet is;

[text]

Beneath is the dtml code used to print the main content of
the type mentioned above ..

Annonse tekst:

.. my problem is that the final output when parsed with the
dtml code above is something like;

['hei', ' jeg er .. p\345 29 \345r som s\370ker .
...angre seri\370st ment. ']

.. how do I get ouput without the [''] .. entries.. 
that is; "clean output" .. as well as how can i get the ascii 
codes like \345 to be the correct html code for norwegian 
caracters?

Would apriciate any input here.. 

Thanks in advance.

Kindest,
Jørgen Skogstad

Sorry to jump in late on the thread, just joined the list.

Is there a reason you can't do this by just messing with the namespaces
stack, ie, adding additional folders to it?

(Or a reason that's not a good idea? That's what I've been known to
do, if I correctly understand your goal...)

Quite simply, Data.fs is appended, not modified, except during a pack
operation.  Think of it like a binary log file.  Therefore there are
only two ways a simple, live backup of Data.fs can fail:

1) You do the copy in the middle of a pack operation.  For most,
packing is a rare operation.  But if this happened, your backup would
be worthless.

2) You get a partly truncated record at the very end.  This is actually
not a big deal, and AFAIK in most cases ZODB is capable of
automatically rolling back a partially committed transaction.

You can.


This would be consistent with "atomic updates."  What it means is
that a transaction is not written to the Data.fs file until it has
completed, and when it is finally written out, it's done as an
atomic operation, i.e. at the system level it is a single write
operation and nothing else happens on the system until it completes.


From that you can infer that if you were reading the Data.fs file
(making your backup copy) at the same time, it would be impossible
to read the file "in the middle of an update."  If both read and
write requests hit Data.fs at essentially the same time, one goes
first and the other waits until the first completes.  So if the
write gets first shot, the read will block until the write (meaning
a completed transaction/update) finishes, and your read will include
that last update.  If your read gets first shot, then it will not
include the update.  You will under no circumstances get *half* an
update.


One of the other things that makes this possible is ZODB being of
a "journaling" nature.  i.e., all updates are *appended* to Data.fs.
This is why you must periodically pack the database, which
conglomerates all the updates back into the base datastore (or
whatever those wacky Zopistas call it. ;) that comprises the first
part of the Data.fs file.


I think that's all correct.  Someone please throttle me senseless
if not.  :-)

[Zope] Version Lock Error

[ksmith]

Hello,

For some reason anonymous users are getting locked out

It doesn't happen right away, only after I've made a

Does anyone have any ideas on what's happening??

Thanks in advance.

RE: [Zope] Version Lock Error

[Chris McDonough]

When the users hit a DTML method that tries (maybe in a roundabout way,
have a ZCatalog?) to write to an object in the ZODB that's been locked
in a version, you'll get this.  Try to figure out where it's happening
by examining the DTML method that they're hitting and figure out where
you're trying to do writes.

Yeah, I find rendering slow on my workstation too. (And mine is reasonably
fast - 450mhz). DocBook does seem to take a while to get your head around the
whole thing, I'm still trying to grok it myself, however it does one thing
that I am really into, that is seperation of content from presentation (note, 
LaTeX also does this to an extent). I find it really handy to be able to give
people documentation to people in the most appropriate format, (HTML for web,
Postscript for print, and RTF for PHBs who use word ;).

The time to compile (for want of a better term) the DocBook into a presentation
format isn't too much of a problem IMHO, since once you become proficient in
its use yuo won't need to compile after each change just to see what it looks
like.

Cheers,

Benno

[Zope] Zope for Client / Server Game advice seeked

[David Stidolph]

I'm working on a Client / Server game.  My plan is to write the 
Gamecode on the server (and some on the client) in Python and use Zope as 

the persistent database solution and interface to the server.  The 
game 
objects will probably be based on C++ objects and I was considering 
using SOAP as the transport for all non-high traffic messages between 

the server and the client (high volume messages will probably have to go 

UDP).  For UI I was thinking of DHTML with a Windows application 

using IE 5.5 embedded in it.This is a high level look at what I was 
considering and I am looking foradvice and opinions - especially in regards 
to Zope or otheralternatives.  I know the magnatude of the project - I 
do have someothers to help, but I am the only one with actual game 
developmentexperience.The game code WILL be Open Source and is 
primarily to teach myself andothers some new technology with a intereasting 
purpose.
Thanks in advance,

[Zope] Kid clicking and Zope thread deadlock

[Hung Jung Lu]

Yikes, I was affraid that I might get kid clicking problems in Zope. And now 
I got it. Help is needed.

"Kid clicking" is a technical term used in multimedia game programs, 
referring to firing multiple click events quickly. The most scary part is 
that under intense clicking, a multi-threaded program would go into 
dead-lock.

I have a Zope application running. When I kid-click on one button, it 
actually locks Zope up. This error does not happen when I run Zope in 
single-thread mode. So, for the bug seems to come from Zope thread 
dead-locking.

Good thing is that it is reproducible. So I will start to trace the origin 
of the deadlock, all the way down into Zope internals if necessary. But help 
will be appreciated.

My Zope is 2.1.6. More info: it happens both with Netscape and IE. More 
info: when kid clicking on the webpage, actual requests are sent to the Zope 
server, I see from the terminal 4 lines about

2000-06-30T00:29:43 PROBLEM(100) ZSybaseDA Changed database context to 
'master'.
Changed database context to 'mydatabase'.

and it then goes into deadlock. Not sure whether it's Sybase or Zope 
problem.

By the way: how can browsers be so stupid as to send requests out for each 
repeated button click? Shouldn't them lock up the webpage right away? 
Browsers do lock up after an anchor is clicked, but why don't they lock up 
after a button is clicked??!! Arrghh...

Hung Jung

Probably. A site that does this has been around for quite a while now:
http://rive.boxybutgood.com/WindowMaker/
(It is down for a while, but will be back up soon (he Says)

For those who have seen the WindowMaker Desktop, that's exactly what it

[Zope] RE: Ref mxODBC and Zope

[Jay, Dylan]

no, but I have since worked out how do it... I think.

The problem is that the DateTime module of mxODBC is compiled. It needs to
be renamed or repackaged to prevent the name confict. Then it needs to be
recompiled. On unix I don't think this is very hard. However I am windows
and this will require me to install MSVC and learn how to compile a python
module dll from c code. This is not something I've had the time for.

So if you or anyone else has achieved this or wants to give it a go I would
dearly love a copy of the resulting dll. A mxODBC DA would drasticly improve
the performance of my site.

I had been latterly thinking this myself and set about trying to do it,
but being new to Zope development, didn't have much success! I presume
it involves modifying the folders PARENTS list, but I wasn't quite sure
how to do that.

[Zope] 2.2b3 hangs a lot

[Bak @ kedai]

hi all
been running 2.2.0b3 for a few days now.  
config
redhat6.1
postgres
ZPygreSql
kmnetnews

after some time, zope just hangs.  when i do top, there's no processor usage at
all on all python processes.  after a few minutes, zopes wake up  and continue
to serve.  the cycle continues after some time.  the hangup is very sporadic.

while this is happening i can still connect to the said port, but can't GET or
PUT anything.

this is a site that used to work on 2.1.6, no major changes.  except for the
updated Lexicon.py provided by Brian.

also, if i started with -Z, how long will it take zope to realize it's not
responding and to restart again? 

if i started Zope with a non default thread, what are the concequences?

anybody experienced zope hangups?  help, pointers, etc, sought!
i hope to document these, for the benefit of others like me.

thanks

Whilst I agree that "It will never happen to me" is a stupid stance, the ATO 
web site was not 'hacked'.  As an example, the Federal Police and the 
government are NOT doing anything to the person.

What happened was somebody noticed that a number in the URL for a page of 
their details matched their ID number, and tried some others.  Upon finding 
they worked, he wrote a script to try numbers, munge the page, and e-mail 
people their details.

This showed a serious flaw in the design of the site, but it was not 'hacked'.

Perhaps the lesson to learn here is: Crackers are NOT the only people you 
need to protect yourself from.

Have a better one,
Curtis Maloney.

[Zope] dhtml-try broken in 2.2.0b3?

[Cary O'Brien]

I was porting some stuff that had a dtml-try to
the newest Zope (2.2.0b3) and I had problems
with a dtml-try block.

I tried a fresh install and had the same problem.

To reproduce, create a DHTML method with


  

  It blew up


Accessing the document errors out with...

  Zope Error

  Zope has encountered an error while publishing this resource.

Any ideas?

[Zope] MySQL Select Statements

[Michael Blewett]

Hi Everyone,
Just need someone to put me straight here. When I use Select statements in 
an SQL Method I cannot simply :

Select Column1, Column2 etc
from TableA.

Instead I must use the AS statement ie

Select Column1 AS Column1, Column2 AS Column2
from TableA.

Is this just an oddity with the MySQLDA/Db adapters or am I overlooking 
something blatantly obvious here? All the examples on zope.org don't have 
the extra "AS Column1" additions on them and I was wondering if this is a 
Zope/mySQL-unique thing.

I'm using Zope (2.1.6) with MySQL (3.22.32) with Zope MySQL Database 
Adapter (ZMySQLDA) 2.0.0a1 and
MySQLdb module release: 0.2.2 .

Could someone please let me know as I don't want to have to type the extra 
bits on all my SQL statements from here on in if I don't need to (I am the 
world's worst and laziest typist). If it is the case that it's a necessary 
evil, then I want to put a HowTo or Tip up on zope.org because it took me a 
while to figure out what I was doing wrong, and if I can save someone else 
that same wasted time then I would like to. However I wanted to get my 
facts straight (via all you experts) first.

Thanks for any help...

[Zope] Traversal of ZODB

[David Trudgett]

I wonder if anyone has a sample Python script that traverses the ZODB to

present requirement is to write a script that goes through and does some 
automated updating of several dozen DTML documents.

Thanks.

[Zope] Search Interface

[David Trudgett]

I'm having some trouble setting up a search interface into a ZCatalog. I 
want to create a text index on the contents of my DTML documents, but I 
can't seem to get it to work. It search on title just fine. I think my 
problem is that I don't know how to create the right index, and what to 
call it (how the body or text of a DTML document is referenced). Can anyone 
enlighten me about this? I might be going blind, but I haven't come across 
anything in the documentation so far that answers my question. I'm about to 
resort to reading the Zope source! (which I think I will need to do sooner 
or later anyway, to get a better understanding of how it all works).

Thanks for any assistance.

Actually, I just used dtml-with.

I'll go ahead and embarrass myself now, and explain what I did. Other
people can chime in with "wow, that was dumb, here's the right way to do
that" as needed (I'd really welcome that, actually!).

My use was, I wanted to be able to pull in things like images, bits of
text, whatever, from a "common" area but not have to litter, perceptually,
the / area of my server. So, being someone used to idioms like
-I/some/other/directory from the various glorified c-preprocessor
"include" systems that I'd used on HTML in previous jobs, I set out to do
that. =)

So, for example, we have /images/ and there are Image objects in there.
But I wanted to be able to just write  while working on
pages, so I wrap the content with 


...



The reason for the inner dtml-with is that my pages are DTML Methods, not
DTML Documents, and the Folders are the "context." If all my content had
"images" shoved on top of the namespaces stack, they'd get even simple
things like  wrong, because that's supposed to come from
the Folder that method lives in... So, I push images onto the namespaces
stack, then push "the parent" (as opposed to grandparent) up on top of the
stack redundantly. This way the acquisition picks up the things like title
from the current folder, and even lets the current folder override some of
the "common" elements, but then falls back to this arbitrarily chosen
folder to go find the other peices next, and then finally goes through the
normal acquisition dance of going up the parents list.

This actually worked out pretty well (boy, was I shocked ;->).

HTH,
jim

Actually what you did is pretty clever, Jim.  It even relies on stable
interfaces.

If we could find some way to effectively communicate the way Zope works
(and what goes on in Jim Fulton's head), the fact that this works
wouldn't be so surprising.  Achieving this is not just about documenting
interfaces, however.  It's also about new design patterns that are made
available through the concept of acquisition.  I hope that the books
being written about Zope go into depth on the new concepts.

Good work!

Depending on  the column names, yes you can.  I just tested it not, and it 
works fine.  If the column names are not valid zope/python names, you will 
run into problems.

Can you try to construct the simplest example of a query that doesn't work?

Hmm.. I am using the same, except for ZMySQLda 1.1.3, and MySQLdb 0.1.2.  So, 
perhaps it's new in ZMySQLda 2.0.

RE: [Zope] MySQL Select Statements

[Ron Bickers]

Why do you say you "must" use the AS statement?  Do you get an error
otherwise?

MySQLdb 0.2.2 is broken when used with ZMySQLDA.  But 0.2.1 works okay for
me.  Andy Dustman (author of the MySQLdb) said he will fix it and hinted
that one should use the ZMySQLDA that is on Zope.org (v1.2.0 now I believe).
Since that one now uses his MySQLdb, he will likely kill off his own DA.

Hi Ron,
If I don't specify my Selects using "AS", I then get the following error

(Where Subjectname was the first field referenced in the DTML document).
Whereas, If I put the SQL as
Select Subjectname AS Subjectname,  etc, then it all works fine.

It's funny that you say 0.2.2 is broken. Apart from this one glitch, it 
works fine for me (although from memory I think we had to do a little bit 
of fiddling at install time to get it to work).
