[Zope-dev] authorization and SQL-methods
Hi I'm using the latest cvs-version of Zope and I seem to not be able to acces ZSql-methods, I get the login-box, but I can't login as anyone (I have tried to login as superuser, myself (owner/manager) and not at all, but all I get is not authorized. The methods do work in management-mode, but not in the actual pages (or in he view-tab for index_html). Everything Aquires security from the root-folder, but that doesn't seem to help any (neither does giving everyone full rights...). And yes I checked to see that the root-folder is setting "Use database methods". So if anyone has any ideas to try, I'd be happy ;) My guess is that it has something to do with the new security patches, but I'm not sure. oh, right, and another thing, could you cool developers of Zope please take a quick look through all the management-tabs and make sure that they don't move around alot like they do now ;), this would speed up productivity a little for us users ;). /Peter Toneby, who finds stability boring ;) -- Alpha Test Version: Too buggy to be released to the paying public.

Re: [Zope-dev] Broken instances when upgrading from 2.1.6 to 2.2

[Zope-dev] Datebug?
I have encountered a strange and irritating problem. As I live in Sweden we use timezone 'GMT+1'. I have a form like this: And when I press submit I come to this page: The input field are correctly displaying the date (in GMT+1) but when I submit the form and use the "fmt" the date is displayed with a decrease of 24 hours. Like if I write 2000-07-21 in the input-field the next page will display 2000-07-20. I I dont format the date on the second page the same date will be shown. It cant really be a timezone issue because it is decreasing the date by 24 hours and I only live 1 hour from GMT. The date on my computer and the server are correct. Does someone knows why this happens when I use "fmt" or is this a DateTime bug? ___ 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] Strange local(?) bug in uploading files
I have a major problem with uploading files. I am doing a form to upload PDF-files This is what it looks like (with only the relevant code): pdf_form: Title: PDF: pdf_method: When I run this code in 2.1.6 it almost works. The content_type is wrong but if you edit this property and set it to "application/pdf" it works. (This is another strange problem.. this should be set automaticlly. I doesnt work when I pass content_type='application/pdf' either.) However when I try to run this in Zope 2.2 i get the following error (with traceback): Error Type: AttributeError Error Value: seek Traceback (innermost last): File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: pdf_method) File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: pdf_method) File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/OFS/DTMLMethod.py, line 167, in __call__ (Object: pdf_method) File /usr/local/new.test.version.of.zope.DO.NOT.REMOVE/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: pdf_method) File /usr/local/zope/lib/python/DocumentTemplate/DT_Util.py, line 342, in eval (Object: manage_addFile(pdfid, file=pdf, title=titlepdf)) (Info: pdf) File, line 0, in ?

Re: [Zope-dev] RE: [Zope] ZPatterns Question
Hi guys, I'm trying to make a simple guestbook using ZClasses and ZPatterns, I suppose this is somewhat overkill, and would be alot easier to do using SQL, but it's for the sake of knowledge (as is everything I do). So I read the IRC-log and asked a question regarding storing a ZClass in a Specialist/Rack, and I suppose that is what I should do too. Also note that I have not done anything with ZClasses or ZPatterns and take this as an oppotunity to learn booth ;). So I have done the following: I created a product and put 2 ZClasses in it, Guestbook and Guestbook_entry. Guestbook_entry was created with Dataskin as baseclass and holds a propertysheet called entry_data. Guestbook has 2 methods that handles the adding of entries, one is the form, the other is the actual dataadder (the forms action) and it's called entry_addProcessor. I then added a specialist to Guestbook, and told it to store Guestbook_entrys, it's called entry_storage. entry_addProcessor contains the following code: Code is supposed to go here... I just have to figure out how to add the data sent to newobj... But when I try to run this I get "Unauthorized" for newItem, and I don't know what settings to set for anonymous to be able to use it, since I can't seem to get it to work even with my user that has created everything. Now, am I correct to put the properties in the ZClass, or should they go into a PersistentSheet or a PersitentSheetProvider plugin? And if I should put it into PersistenSheets should I change anything in the Sheet_Names and Sheet_Namespaces boxes or just att my properties? And what about the Unauthorized error, should I change something in the define permissions tab? Now, if I could get this little question answered in english (not ZPatternish), I would be very happy, and if you get me to grasp these things I think quite a few others will grasp it too, and you will get less requests for basic dokumentation, and everyone will be happy and live long and prosper forever after. /Peter Toneby, who really should go to bed now. -- Alpha Test Version: Too buggy to be released to the paying public.

[Zope-dev] Wrap or not wrap i Zope source
What I want to do is simple.
Modify the source of Zope so that one can select either wrap=off or
wrap=virtual in the textarea box of the documentEdit.dtml
I bet you all recognize these HTML bits (documentEdit.dtml):
And I want to add:
This submitbutton should trigger the simple following DTML
(documentEdit.dtml):
WRAP="virtual"
WRAP="Off"
I have checked the python source, but I'm definitly not a wiz or very good
with OOP.
The documentEdit.dtml document "actions" the form to manage_edit() found in
DTMLDocument.py and DTMLMethod.py:
def manage_edit(self,data,title,SUBMIT='Change',dtpref_cols='50',
dtpref_rows='20',REQUEST=None):
"""
Replaces a Documents contents with Data, Title with Title.
The SUBMIT parameter is also used to change the size of the editing
area on the default Document edit screen. If the value is
"Smaller",
the rows and columns decrease by 5. If the value is "Bigger", the
rows and columns increase by 5. If any other or no value is
supplied,
the data gets checked for DTML errors and is saved.
"""
self._validateProxy(REQUEST)
if self._size_changes.has_key(SUBMIT):
return
self._er(data,title,SUBMIT,dtpref_cols,dtpref_rows,REQUEST)
self.title=str(title)
if type(data) is not type(''): data=data.read()
self.munge(data)
if REQUEST:
message="Content changed."
return
self.manage_main(self,REQUEST,manage_tabs_message=message)
The _er method is found in DTMLMethod.py
def _er(self,data,title,SUBMIT,dtpref_cols,dtpref_rows,REQUEST):
dr,dc = self._size_changes[SUBMIT]
rows=max(1,atoi(dtpref_rows)+dr)
cols=max(40,atoi(dtpref_cols)+dc)
e=(DateTime('GMT') + 365).rfc822()
resp=REQUEST['RESPONSE']
resp.setCookie('dtpref_rows',str(rows),path='/',expires=e)
resp.setCookie('dtpref_cols',str(cols),path='/',expires=e)
return self.manage_main(
self,REQUEST,title=title,__str__=self.quotedHTML(data),
dtpref_cols=cols,dtpref_rows=rows)
I GUESS that it is in this method I do my changes (together with parameters
in manage_edit() [DTMLDocument.py and DTMLMethod.py])
Maybe something like this:
if wrap_cookie is 'off':
resp.setCookie('wrap_cookie','virtual',path='/',expires=e)
newwrap_status='virtual'
else:
resp.setCookie('wrap_cookie','off',path='/',expires=e)
newwrap_status='off'
...and...
return self.manage_main(
self,REQUEST,title=title,__str__=self.quotedHTML(data),
dtpref_cols=cols,dtpref_rows=rows,wrap_or_not=newwrap_status)
I don't dare to do anything yet, because I feel a bit unfonfy about changing
source at this level.
Can you please give me some hints or advice or maybe you already have this
done.

[Zope-dev] Cache-bug in handling of files
I started this thread on the regular zope mailinglist but now I found a similar posting to my problem in the archives. I have fileobjects where I store pdf-files. If I want to change the pdf-file I use the method "manage_upload". The problem is that if I try to view it it always choose the one that is in the cache. It displays the new one if I open it in a new window or if I save it to disk. The filesize and everything else is for the new file. The thread I found was this: http://zope.nipltd.com/public/lists/zope-archive.nsf/Main/AED89A938194225580256857007679ED?OpenDocument&mode=subject&topic=[Zope]Dumbobjectaliasingquestion This points to a bug report and after serching for it I found it: [754] Zope Bug: Uploaded Images Don't Appear Immediately Category: General Last Updated: Oct 29, 1999 7:05 am Submitted On: Oct 12, 1999 3:58 am Status: Ongoing Reported Version: 2.0.1 Expected/Fixed Version: The strange thing is that this is still Ongoing after almost a year since it was submitted!

I think it should work well with PropertyManager
Usage (works for me):
- Define your own edit form
- Derive your class from PropertyManager
- Add a propertysheet to a class instance, eg.:
def __init__(self):
self.propertysheets.manage_addPropertySheet('advanced', 'advanced')
- Add a prop:
advanced.manage_addProperty('something', 0, 'int')
- Do something with your propsheet, eg. update it:
adv = self.propertysheets.get('advanced')
if REQUEST is not None:
return self.manage_advancedForm(
REQUEST,
manage_tabs_message='Advanced Settings updated.',
)
- Or read a property:
self.propertysheets.get('advanced').something
If you're having problems just shout.
cheers!

[Zope-dev] What does error code 136 mean?
Hi, I am having trouble with the current version of ZWiki. ZWiki's author is puzzled, and suggested that I try one of the Zope lists. I set up a ZCatalog on a ZWiki folder as described at http://zwiki.org/HowToInstallAZwikiCatalog The following DTML from ZWiki's RecentChanges: causes a python core file to be produced, and with stupid log enabled I get this message: 2002-09-02T09:57:30 ERROR(200) zdaemon zdaemon: Mon Sep 2 10:57:30 2002: Aiieee! 322190 exited with error code: 136 I am using Zope 2.5.1 with python 2.1.3 under HP (was Compaq) Tru64 Unix version 5.0 Does anyone have any suggestions about what is going wrong?

Re: [Zope-dev] What does error code 136 mean?
Hi,
I have tried Leonardo's very helpful suggestion to get a Python traceback:
> Try to run zope under a debugger. Follow instructions here:
> http://www.zope.org/Members/4am/debugspinningzope
> but type "continue" (w/out quotes) as soon as you get the gdb prompt to

This, combined with some debugging of the corefile at the C level (which I
know a lot more about than anything to do with Python) has helped me
figure out what the problem is.
The DTML that was cauisng the crash was:
but some items in Catalog did not have a property lastEditTime. In my
particular circumstances I can exclude these objects from the ZCatalog,
but surely there ought to be a cleaner way of handling this - either
putting objects with missing properties at the end of the list, or not
having them feature in the list at all? Perhaps some way of controlling
this (or at least raising a more meaningful error) might be considered in
a future release of Zope?
The gory details I've appended the Python traceback. You can see the
problem call to sort in lib/python/DocumentTemplate/DT_In.py .
Why a SIGFPE? Dates seem to get converted to C doubles by Python for
comparison. From debugging the core file, line 345 in
Objects/floatobject.c in the python v2.1.3 source is causing the problem:
340 static int
341 float_compare(PyFloatObject *v, PyFloatObject *w)
342 {
343 double i = v->ob_fval;
344 double j = w->ob_fval;
> 345 return (i < j) ? -1 : (i > j) ? 1 : 0;
346 }
347
w is a missing python object with a junk w->ob_fval, which presumably
comes from the missing lastEditTime property of one of the objects
involved in the comparison:
(ladebug) p *w.ob_type
struct _typeobject {
...snip...
tp_name = 0x3fa0648="Missing";
...snip...
tp_doc = 0x3fa04d0[Ladebug Warning: String is too long to display.

Re: [Zope-dev] Newbie Question
Aaron Paxson wrote: I hope I'm posting to the right mailing list. There were so many to decide from. This should've probably been directed to the main Zope list; zope-dev is for development *of* Zope. I've just been introduced to Zope, and am curious on how it will fit into my company's plans. I'm currently learning Java, and was starting to learn the RedHat Web Application Framework. I've found Zope in an article on the web, and started to look into it. It looks to be just as scalable, but I'm curious on how extensible it is, as well as, it's power in a corporate environment. For example, how extensible is it, to modify the security module and have it authenticate against LDAP? (I don't want all my users to remember yet another password) Also, how powerful is Python as compared to Java? Since it uses a native compiler, it stands to reason that it would be faster than Java, but what of it's objects and packages? (i.e. Does it have an image manipulation package, or networking packages?) There are Add-ons that do User authentification against LDAP servers, and its also not very hard to roll your own. Zope is, generally speaking, *very* extensible -- see for example the long list of 3rd pary add-on products at http://www.zope.org/Products I think Python is one of the greatest strengths of Zope. Its not only a modern full-fledged OOP language, comes with great libraries (see http://python.org/doc/current/modindex.html, and has even more to download separately) but is simply a joy to program in. Bruce Eckel put it very nicely IMHO: http://mindview.net/FAQ/FAQ-012 ) Also see: http://csdl.computer.org/comp/mags/co/2000/10/rx023abs.htm http://www.cis.udel.edu/~silber/470STUFF/article.pdf http://www.twistedmatrix.com/users/glyph/rant/python-vs-java.html There are good networking modules in the standard Python distribution; image manipulation can be done with eg. PIL (http://www.pythonware.com/products/pil/) or PythonMagick (http://www.procoders.net/moinmoin/PythonMagick) I must say, seeing the documentation and books alone, tells me the product is good, and something I can learn. I see alot of "Hope for Zope" , but I don't want to get into it, just to see if it doesn't fit into my plans. For those who want a couple of examples, I have 3 projects for our intranet/extranet/internet applications: 1). Images and cataloging (where, our development team can upload their images, and the intranet application will take that image and export it to a JPG to update the web catalog, and move the original file to our FTP site for our photographers. 2). Document Management (Uploading of files, and inputting data to index on those files for searching) 3). Obviously the usual (Content Management and Portals) which I'm sure Zope does a good job at. Those are certainly suited for Zope - peter. Thanks in advance!! Again, my apologies if there is a better list for this post.

Re: [Zope-dev] Zope Start Script Woes
I'm no big shell scripter, some suggestions anyway...
* I think you might be missing an INSTANCE_HOME parameter here,
something like
# what we'd like but won't recognize instance home
# exec /usr/bin/python $ZOPE_BASE/z2.py -z $ZOPE_BASE -u $USER \
# -w $HTTP_PORT -f $FTP_PORT -t $THREADS -Z $MANAGER \
# -l $INSTANCE_HOME$ZOPE_LOGFILE \
INSTANCE_HOME=$INSTANCE_HOME \
# -D "$@" $INSTANCE_HOME/var/startup.log &
or export the INSTANCE_HOME
* Are you shure you want to start Zope in debug mode?
* You might want to check
http://zope.org/Documentation/Books/ZopeBook/2_6Edition/MaintainingZope.stx
, I put some (very much simpler) startup scripts there
* Finally, the upcoming Zope 2.7 should behave much better wrt this (if
thats any help to you :-))

Hi,
These are probably more shell scripting issues, but I'm hoping that
some scripter with an agile mind will show me the error of my ways,
so here goes.
I have borrowed a script from the zope site and modified it for my
purposes, and it 'sort of' works. The issues are:
Can't seem to get the Instance-Home stuff to work right without local
start scripts in each directory. Right below the $INSTANCE_HOME/start
is the line I'd like to use to simplify the management of the
instances.
Can't get stop to work right. First 'stop' is not an instance, then
the first instance does appear to get stopped, but it errors on the
other two.
I get a 'start0' for the value of $WAIT in the starting text display.
(should just be a big fat zero or one!)
And for some reason, the script dumps the entire local environment to
the display before it does anything; any ideas why?
All constructive criticism welcome, and I'll take some flames

Re: [Zope-dev] How to make Zope fail nicely under high load?
This very much depends on your application and requirements (and your definition of "nicely" :-)), but I'd argue that it rarely make sense to handle this at the TCP Connection level (just to think about browsers opening multiple connections, HTTP/1.0 or /1.1 compliant browsers, proxies etc.) As an example, one client of ours had the following requirements wrt. to this problem which I think should be fairly common: * Allow X logged-in users till a certain responsiveness threshold is reached * If said threshold is reached: - inform all users trying to log that the site is too loaded - while allowing already-logged-in users to still use the site with acceptable speed This means we had to a) measure responsiveness (which we did with some cobbled together heuristic involving the rate of user logins (something like 5 users per minute) and an external script effectively "HTTP Pinging" the site every X minutes) and b) redirecting users to a statically hosted page (which can be served cheaply) if said conditions were met. This kind of thing clearly cannot be done at the TCP level because TCP Connection != User session cheers, peter. Bjorn Stabell wrote: Hi, We've run into an interesting problem when load-testing a Zope site behind Apache, a problem that we've also encountered in real life. Basically, when the load gets high, Zope has a huge backload of work (several minutes of requests), making the average latency for each request many minutes. What are effective ways to do this kind of overload management so that the backlog of work doesn't get that big? The ideal would be for requests to fail immediately if the backlog of work is more than a certain number of requests (or even better, estimated time to process). Here's what we've tried: Naively, we thought we could just set the socket.listen() backlog in Apache and Zope to a lower value, but in TCP connect()'s apparently don't fail if the server's listen backlog is full; instead requests are retried, resulting in a client side managed "listen backlog", also giving the same long latency. (If someone knows this stuff, please confirm/deny these allegations against TCP :) It appears the way to control it would for Apache or Zope to return "503 Service Unavailable" when the load is too high, but we haven't found a good way to do this; Zope doesn't appear to have any mechanism for it, and Apache's ProxyPass doesn't either. I guess load balancers would, but that's a bit overkill since we run the server on one machine.

+1 from me I think its a great idea, I also agree with Jamie about HTTP cache control feeling awkward at the moment not sure how it could be better though Jamie Heilman wrote: Chris McDonough wrote: http://dev.zope.org/Wikis/DevSite/Proposals/FasterStaticContentServing Sounds good. WRT your comments on the need for a cache multiplexer so one can handle the case of HTTP cache control headers & opaque server-side caches working together--I'm really wondering if a better solution isn't to just remove the cache header manipulations from where they are now (in a seperate product) and integrate it more into an API any where object [that wants to] can use. HTTP cache control really is a protocol level thing, and the way its bundled as an add-on service right now feels pretty awkward.

Currently it's just an exact copy of the 2.6 Edition book (comments and all). I think the plan should be for people to: 1. take ownership of a chapter or two 2. address all the comments in the chapter and get rid of comments in places you've addressed. 3. update any material that is wrong wrt to differences between 2.6 and 2.7. The "prize" for taking ownership and updating two complete chapters is your name as a coauthor on the front page (as before ;-). Erm, "there is no front page... you need to realise the truth: its you who is the front page" Another thing to do is to incorporate some of John Whitener's changes "the lost chapter" referenced all over the place within book comments. I wonder if he's still around. Yes he is, I talked about this to him some time ago. In light of this its maybe best if I do the incorporating At some point in the future, we can "backport" some of the changes to the 2.6 book if someone wants to take on that responsibility. It's advisable to use external editor to make the changes or to maybe use FTP to get "sandboxed" local copies of the book and make changes reuploading them as necessary. I've lost track of whether FTP access is possible or not on Zope.org at this point, however. Does anyone know? I've tried a few ports but nothing. Hm, we should make the sources available somewhere. Once Zope.org starts working again. Also, Zope.org is so slow for each request when you're logged in that we may need to move development to another system.

[Zope-dev] already have current data for oid
Hi, I am experimenting with ZEO. Sometimes I get this Error: ValueError: already have current data for oid (Also, the following error occurred while attempting to render the standard error message, please see the event log for full details: already have current data for oid) It starts with one URL in one ZEO-Client and after some time the whole ZEO-System gets "infected". A restart of the ZEO components is needed to make everything work properly again then. In addition to that sometimes it seems that not every change in ZODB gets anticipated by every ZEO-Client. Some Clients insist on delivering "Ressource not found" while some others find these new objects. The whole thing is complete unpredictable and seems not to follow any rules. Our system: Apache - Pound - 5x ZEO-Client - ZEO-Server Zope 2.8.5 The Server has 2 CPUs. I am experimenting on this machine alone in the moment. So the load should be on a minimum at all. What could be the reason for this here?
