[Zope-dev] HEADS UP: QA Problems with Zope 2

2005-04-04 Thread Christian Theune
Hi,

as I'm the guy who clicks the build button for the Zope 2 Windows
releases I have the unfortunate honor to write his complaining mail:

Situation
=

a) Zope 2.8 as of release a2 does not run bin/test.py anymore. Neither
on Linux nor on Windows. Unfortunately this is the only testrunner
worked on Windows at all. Now it is broken as well. (Import problems
from Five.products or something)

b) The WinBuilder environment isn't version managed along the Zope
branches. The change of the Zope module to Zope2 required manual changes
in the WinBuilder structure that broke and didn't got detected during
continous tests. (See c) Additionally the requirements of specific
versions Python, ZODB, winutils etc. are hardcoded in the Makefiles
right now.

c) There are no nightly tests for Windows at all. I know there is some
suspended effort already around. Please notice this as a friendly
reminder that I'd be very lucky having those catch errors *before*
Andreas makes a release and I run the tests manually.

d) zopectl on windows doesn't work (it barfs about SIG_CHILD not
existing). I'm not sure if it ever did or if it should. If it should not
work on windows anyway, maybe we should remove it in the windows
distribution ...

All in all, it's a very unsatisfying situation for the Windows users,
and I'm pretty scared telling anybody about the situation when I'm
asked. This really has to change at least a bit.

What to do
==

Things I can do and propose to do to make this better:
--

b): I can either create branches for WinBuilders responding to the Zope
Versions. Or (what I like better) I can put the WinBuilders
somewhere in the Zope 2 tree to allow versioning along a branch
automatically so continuous tests know where to get the WinBuilders
from.

c): If there is some infrastructure with the build bot around already
and someone gives me pointers, I can set up nightly builds and
tests on a Win2k machine over here. Additionally the tests should
run on XP Server (or professional) and Win 2003 server as well. I
don't have those around unfortunately + I don't have enough Visual
Studio licenses around. Anyway, having at least one continuously
running test is better than having none.

Things I can't do anything right now on my own and need support:


a) I'm not able to look into the test runners (that are not broken
   solely on windows) nor to look into Five integration problems. I'd
   love if someone could a) either fix test.py or b) deprecate it and
   give me the hint to some other runner that works. 

   test.py is included and should therefore work within a release or be
   removed. I'm not sure what is right here.

d) I have no idea about zopectl on windows. Is there some knowledge
   around on this?


Final conclusion


I have a compiled Zope 2.8a2 around here, but I'm not able to run the
unit tests on it and I'm not willing to publish it therefore because I
have the suspicion that this branch never has seen windows before except
the one pass of unit tests before 2.8a1.

Cheers,
Christian

I just added some missing files to setup.py. Could you please try again? 
There are still some broken z3 tests (setup works different for z3), but 
at least on linux test.py works now.

+1 from me on merging WinBuilders into Zope.  It took me quite some time to
locate it first I looked, and having it external reinforces the 2nd-class
status of Windows.

 d) I have no idea about zopectl on windows. Is there some knowledge
around on this?

I recall a message from Tim saying it has never worked and probably never
will.  IIUC correctly, its functionality isn't as desired on Windows due to
the service support.  Enfold has a simple log rotation strategy I have
detailed in a previous mail to this list, and we will contribute code
shortly.

I have on my todo list for the next week (or 2) to steer through my service
changes on both the 2.7 and 2.8 brances as discussed here recently.  If that
goes well, the Zope3 trunk will get a look-in too :)

Yeah, I just wanted to try it for running 'zopectl test' but it fails
earlier. Maybe it shouldn't be delivered then.

Re: [Zope-dev] opinion: speeding up large PUT uploads

2005-04-04 Thread Florent Guillaume
Chris McDonough  [EMAIL PROTECTED] wrote:
 Zope's ZPublisher.HTTPRequest.HTTPRequest class has a method named
 processInputs.  This method is responsible for parsing the body of all
 requests.  It parses all upload bodies regardless of method: PUT, POST,
 GET, HEAD, etc.  In doing so, it uses Python's FieldStorage module to
 potentially break apart multipart/* bodies into their respective parts. 
 Every invocation of FieldStorage creates a tempfile that is a copy of
 the entire upload body.
 
 So in the common case, when a large file is uploaded via HTTP PUT (both
 DAV and external editor use PUT exclusively), here's what happens:
 
 - ZServer creates a tempfile T1 to hold the file body as it gets
   pulled in.
 
 - When the request makes it to the publisher, processInputs is called
   and it hands off tempfile T1 to FieldStorage.
 
 - FieldStorage reads the entire body and creates another tempfile
   T2 (an exact copy of T1*, in the case of a PUT request).
 
 - T2 is eventually put into REQUEST['BODYFILE'].
 
 (*) At least I can't imagine a case where it's not an exact copy.
 
 This is costly on large uploads.  I'd like to change the top of the
 processInputs method to do this:
 
 if method == 'PUT':
 # we don't need to do any real input processing if we are
 # handling a PUT request.
 self._file = self.stdin
 return
 
 Can anyone think of a reason I shouldn't do this?

Is stdin the medusa stream or T1 at this point ? Because for
ConflictError retry we need an input that is seekable (HTTPRequest.retry
does self.stdin.seek(0)).

[Zope-dev] Re: brain.getObject and traversal

2005-04-04 Thread Chris Withers
Hi Tres,
We really need to follow a deprecation-style model here:  the risk of
breaking major third party components is pretty high.
Agreed. I see you started working on this, thanks!
Since this is a bug, and it looks like it's going to be fixed with a 
config option, would anyone mind if I ported this code to the 2.7 branch 
with the option set to do whatever 2.7.5 does?

The CHANGELOG should highlight the change, and include the zope.conf
snippet required to restore the old behavior.  We could add a
deprecation warning (if that entry is activated), that the old-style
option would be removed in 2.10.
Sounds good to me.
cheers,
Chris

Please don't catch any exceptions and re-raise them in a different type, 
just let them pass through.

I specifically don't think raising a normal NotFound when the catalog 
has a brain that doesn't map to an object is the right thing to do. I'd 
much prefer a BrainHasNoMatchingObject exception or some such which is 
nice and clear...

FYI, I usually run the Zope trunk tests once a day, on WinXP.  None of
this goes thru WinBuilders, though -- this is doing test.py -vv
--all from the root of a trunk checkout immediately after setup.py
build_ext -i.

The same two tests have been broken there since last October, but all
other tests pass:

http://www.zope.org/Collectors/Zope/1728

As recorded in the bug that points at, for related reasons an
installed Zope 2.8 is probably unusable on Windows (I haven't tried
this since last October -- don't see a point so long as the 1728 bug
remains):

 Agreed. I see you started working on this, thanks!
 
 Since this is a bug, and it looks like it's going to be fixed with a
 config option, would anyone mind if I ported this code to the 2.7 branch
 with the option set to do whatever 2.7.5 does?

- -0.  This change is not a bugfix -- this is a new feature, which changes
the documented behavior of the catalog brains.  It is really up to
Andreas whether or not to accept such a change on the 2.7 line.

 The CHANGELOG should highlight the change, and include the zope.conf
 snippet required to restore the old behavior.  We could add a
 deprecation warning (if that entry is activated), that the old-style
 option would be removed in 2.10.

 d) I have no idea about zopectl on windows. Is there some knowledge
around on this?

[Mark Hammond]
 I recall a message from Tim saying it has never worked and probably never
 will.

Well, everything that builds on zdaemon is Unix-specific --  the
underlying machinery uses stuff like this freely and ubiquitously:

+ Unix domain sockets.

+ os.fork()

+ The signals signal.SIGTERM, signal.SIGHUP, signal.SIGINT, and
   signal.SIGCHLD, with Unix semantics.

If nothing else, it's a wonderful demonstration of how core Python
allows writing wholly platform-specific code.

 IIUC correctly, its functionality isn't as desired on Windows due to
 the service support.

Unix-heads certainly want it anyway; Windows-heads aren't used to
anything better than the Windows services API, so they don't even
bring it up.

 Enfold has a simple log rotation strategy I have detailed in a previous mail 
 to
 this list, and we will contribute code shortly.

Check it in too!  Nobody is volunteering to look at your patches, and
they're important.  I can't make time for it myself (would if I
could).

 I have on my todo list for the next week (or 2) to steer through my service
 changes on both the 2.7 and 2.8 brances as discussed here recently.  If that
 goes well, the Zope3 trunk will get a look-in too :)

The Zope3 Windows installers to date are produced via setup.py
bdist_wininst, and that's all.  No Windows service support, no
bundling of Python, no bundling of win32all, ..., the Zope3 Windows
story really has nothing in common with Zope2's so far.  That's a
discussion for zope3-dev, though.

 Printing-the-contrib-form-now ly,

Thank you.  Poor Mark 0.5 wink.

I have a compiled Zope 2.8a2 around here, but I'm not able to run the

have the suspicion that this branch never has seen windows before except
the one pass of unit tests before 2.8a1.

FYI, I usually run the Zope trunk tests once a day, on WinXP.  None of
this goes thru WinBuilders, though -- this is doing test.py -vv

build_ext -i.
AFAICS the problem is that *everybody* runs the tests in-place. So 
nobody tests if setup.py installs Zope correctly and people often forget 
to make sure setup.py installs newly added packages and files.

Well, it's not so much as API, but the fact that Windows people are
used to starting a service through the control panel, and not through
a python-script. After all, you don't need the python script. ;)

Possibly zopectl could start the service if it's called on a windows
machine, instead of trying to pretend that it runs on unix... I don't
know how hard that would be.
Also, I don't know how hard it would be to get rid of the unix
specific things for running zopectl test and such...

I'd like a post-publishing hook that's called in the initial REQUEST

I haven't been folowing this thread, so I asked Gary what it was about. :)
Based on that, I'd like to suggest:
There are two possibilities:
1. A post publishing hook.  I think this would be appropriate
   in the case where you really want to augment the publishing
   process.  For example, I hpe someday to use something like
   this to provide another way (other than metal) to provide

   Unfortunately, I think there are a lot of open issues, at least
   in my mind, about how something like this should work.
What I had in mind was, just after Publish.publish calls
result = mapply(object, request.args, request, ...)
add:
if hasattr(request, 'runPostPublishingHooks'):
result = request.runPostPublishingHooks(result, request, 
response)

And a simple system for registering hooks.

[Zope] Re: login page problem

2005-04-04 Thread prabuddha ray
Hi list,
never before i got such a holistic advice.
thanks so much Cliff.

About the 1st mail,

On Sat, 02 Apr 2005 17:03:56 +0100, Cliff Ford [EMAIL PROTECTED] wrote:
 Customisation of the login sequence is quite difficult for Newbies
 because there are lots of different ways to approach the problem - you
 have already tried some. I suspect that trying to match what was done in
 PHP may be part of your problem. It would be helpful to know if your
 lists of users are coming from one source, like a database table, or
 multiple sources, like multiple tables or different databases, and
 whether users are unique in each district

I dint want to built customized login page in 1st place. Actually this
is a Govt. stores management site used in my state only bulit all in
ASP. I 've to convert this into a Zope and Plone version.
So i wanted to get it converted with minimun changes.
But now as you say i think I should go the way Zope does it . only
that i'm finding it hard to customize it in Zope.

1 the district name and their users come from 2 seperate Mysql
tables. the users are unique in each district.

 From there you decide your
 zope folder structure. It could be like this:

 site_home
 |__acl_users
 |__district1
 |__district2

 or like this:

 site_home
 |__district1
 ||__acl_users
 |__district2
 ||__acl_users

 In the second case you would not have to worry about asking the user for
 the district name. In the first case you would get a district name or a
 user defined role for that district from a supplementary data source,
 like a database.

So i think 2nd structure is abetter fit.
Now the qusetion is how do build this district user folder structure
using the database?
Hope not manually, because there are 22 districts and about 15 users
in each of them pluys head quarters.

 A combination of exUserFolder and MySQL would do.

i don know about them, something like mysqluserfolder or
simpleuserfolder components ?

 You can get information on the logged in user (Username and Roles) from
 the User object, so you don't need to expicitly use sessions at this
 stage. You should certainly not store passwords - that would be a 
 serious breach of confidentiality.
 Maybe you should say what you do with the District parameter after the
 user has logged in.

I dont need the password but do need the username and district for
following pages to decide the access rights and the stores available
inthe districts , also for some report labels.

 Giving advice or examples on ZPT and Python for an
 approach that is probably wrong is just too time-consuming.

 Cliff

i dint get to know much about coding ZPT's and Script(Python) for them,
 from the ZPT refs and Zopebook. So wanted some simple working examples.

About 2nd mail,

On Sun, 03 Apr 2005 09:39:01 +0100, Cliff Ford [EMAIL PROTECTED] wrote:
 I have been trying to think of ways of providing specific pointers, So, 
 assuming you have a custom login page and a custom python script that 
 processes that page:
 
 In the Python script you could set a cookie for the District:
 
 context.REQUEST.RESPONSE.setCookie('District', district)
 
 where district is the name of the District field in the form. The 
 District parameter is then always available to your page templates and 
 scripts in the REQUEST object.
 
 At the end of your login script you would typically redirect to some 
 specific page like this:
 
 return context.REQUEST.RESPONSE.redirect('aURL')
 
 in exUserFolder you don't have to do anything else - the login works by 
 magic, which is very confusing.


Are these above said things not possible in exUserFolder. how do i
customize it for my problem?

 
 Now for the problems:
 
 If the login is wrong the system will call /standard_error_message, so 
 you have to customise that to send the user back to the login form with 
 a Login failed message.
 
 If the user bookmarks a protected page and tries to jump to it without 
 being logged in, the system will call the login sequence starting in 
 acl_users, so you have to customise that to call your own login page.
 
 After the user has logged in, whenever you need to get the Username you 
 would typically use a python script like this:
 
 from AccessControl import getSecurityManager
 return getSecurityManager().getUser().getUserName()
 
 HTH
 
 Cliff

So this is what can be done if I use exUserFolder ?
Hope a reply soon.

Python scripts (the TTW kind) have security restrictions and have 
special procedures for setting the name and the parameters of a method. 
(Via the TTW forms: notice that you don't write def methodname() et al.) 
There are also some special names bound, like context and so forth.

External methods are regular Python methods in a Python module which are 
made available to be used live in Zope. Just as in any Python method, 
you can get to the context in which it was called through the 'self' 
parameter, which you will define as the first param. This is the same as 
'context' in a Python script. So you can say::

  def getThisId(self):
return self.getId()
You can get the request like 'self.REQUEST'. The container can be found 
with self.aq_inner.aq_parent or something like that.

Alternately, you can allow modules in Python scripts. See 
zope/lib/python/Products/PythonScripts/README or

Re: [Zope] script or external method ?

2005-04-04 Thread Lennart Regebro
Congratulations: You immediately ran into a limitation of Python
Scripts, and then equally quickly into one of external methods. That's
good, because that means you don't get stuck into the wrong way of
programming. :-)

The right way of doing Zope development is with filesystem python products.

Not Python Scripts, not External Methods, not ZClasses and not DTML.
Each of these may have their place, the best generic way is file
system products. I don't know what is the best starting point
nowadays, but I think doing the Boring Product tutorial still seems
popular:

http://www.zope.org/Members/gtk/Boring/HowTo-Boring


For Zope development there is today basicaly two and a half different
paths to go:

One: Zope2 (which is what you started with now). This gives you access
to loads of products and a huge community to support you. This is the
right way to go if you are interested in using Zope for creating a web
site. Primarily you have a whole bunch of different content management
systems to select from (CPS, Plone and several more) to get you
started. There are also blog software and wikis and stuff that can be
used with these.

Two: Zope3. If you are more interested in developing the system, and
you want a good development framework as your reference to j2ee
indicates, then Zope 3 may be the path for you. It doesn't have that
much of all this modules like Zope2 does, but the development
framework is SO much better. I sincerely doubt there is anything even
remotely this cool anywhere else in the webworld.

The drawbacks of Zope 3 is that you'll have to develop more yourself,
and it is a bit harder to get started with.

Two and a half: Five/Zope2.8. This is a way to use the Zope3 framework
under Zope2. It's mostly of interest for people who have legacy
products under Zope2.

Hi there!
I am running a Debian Linux box with Debian/testing (Sarge) and I am trying to 
get Plone up and running. I have made a clean, new install of the whole 
system last week, so all packages are really up-to-date and there was no 
dirty installation that was updated.

I have noticed that the Plone package on Debian is or was somewhat broken, but 
there was a notice about that on the Plone website (download page) which has 
disappeared. For me that looked like this problem was fixed by the package 
maintainer.

Unfortunately still, after installing Plone (and implicitly thus Zope 2.7) 
Zope did not want to come up, saying:

Did you read the debconf-pages that were presented to you during the
installation of zope and plone? I guess not, because else you won't
ask that question. Short answer: create a new Zope instance using
mkzope2.7instance, check it's config and remove the '#' on the lines:
products /usr/lib/zope2.7/lib/python/Products
products /usr/lib/zope/lib/python/Products
products $INSTANCE/Products
To have Zope 2.7 find the Plone Product. The documentation of Zope and
Plone will explain why you need to do that.

 Zope starting all instances
 '*' is an old/purged instance, not started

Looks like Zope2.7 finds an old 2.6 instance, but I'm not sure...

Sorry Eva,
You'll need to explain your problem more succintly for people to be able 
to help. If you really do need to scrape the urls from the text, then a

Hello,
I've been puzzling over something but can't figure out a solution. I  
have an RSS feed providing the content behind all the links on this  
page: http://demo.plinkit.org/interestsideas/goodreads/booklists.

There's a nice bookmarklet tool in the world called LibraryLookup that  
lets you check whether a book you find on Amazon or something is in  
your library's catalog by scraping up the ISBN and launching an ISBN  
catalog search. It's a javascript, really. I thought I would adapt this

to create a little add-on for the stuff the bestsellers RSS brings back
to my site. What I need to do is pluck out the ISBNs in the links on a  
page like this one:  
http://demo.plinkit.org/interestsideas/goodreads/sinList?synmap=Hardcove
rFiction

The ISBNs are all in the URLs for the book titles  
(isbn=Some10digitNumberHere). How would I look for a piece of text in

that shape, i.e., isbn=5893193390, then, if it's there, copy and paste  
that piece of information into the LibraryLookup javascript I have. The

end result should be that, if there's an ISBN in a feed result, an extra
link  
appears for each entry that says something like Check the catalog,  
which you can click to look that book up in your own library's catalog.

I've been staring at the template that formats the RSS feed to figure  
out whether any TAL expression would work for this. I've been playing  
with a short Python script, then wondering how to call it within that  
template, but I think I have to use regular expressions to do it.

I'm sorry to be so lost on this, but I guess I am. I'd love to do  
something cool like this for our little Plinkit libraries. Can anyone  
help? I'll take anything from a broad strategy to actual code snippets  
(I'm a terrible programmer but a good librarian).

Thanks

Sure it is, but the problem is that supporting it in future versions
of Zope very well may need changes in Zope itself.  Changes that is
*far* from trivial. So I think it's mostly a question of Should Zope
corp put down the effort to keep ZClasses working, because, most
likely nobody else can...

As zope doesn't run on Iron python the impact will be small. it's nice
for people that are forced to run .NET to be able to do it in Python
though. And it does marginally widen .NETs appeal, but only
marginally. :-)

[Zope] Set MIME type using ZPT

2005-04-04 Thread srikanth
Hi,

  I am using an external method to load an Image from the harddrive. The
external method is as follows:

from email.MIMEImage import MIMEImage
##parameters=filename
def getDocument(filename):
  fname = '/mnt/'+filename;
input = open(fname,'r')
content = MIMEImage( input.read( ) )
input.close( )
return content


When I try to display the content in the webpage what I actually got is
all raw data of the file rather the image. 
So how can I convert the raw data to be dispalyed as image in the
webpage. I am using ZPT to display the web page (image). If its dtml I
could have used dtml-mime tag is there any equivalent to that in ZPT.

Any suggestion would be a gr8 help.

Ta.

Re: [Zope] Problem with Z Psycopg

I'm having a problem with Z Psycopg.  From time to time (quite often)
it looses the connection with the database and I get:
   Site Error
   An error was encountered while publishing this resource.
   Error Type: OperationalError
   Error Value: no connection to the server
Then I have to login then close and open the connection.  It then
works for a while before bailing again.
Does anyone know what would be causing this?
Zope Version (Zope 2.7.3-0, python 2.3.4, linux2)
Python Version 2.3.4 (#1, Oct 13 2004, 21:44:19) [GCC 2.95.4 20011002
(Debian prerelease)]
And ZPsycopg is version 1.11
Not sure, but I can report seeing the same thing on a different setup
FreeBSD 4.8
Zope 2.7.5
Python 2.3.5
psycopg 1.1.18 (linked to PostgreSQL 8.0.1 client library)
(PostgreSQL server is also 8.0.1, but on FreeBSD 5.2.1)
On the very same machine I also have
Zope 2.6.1
Python 2.1.3
psysopg 1.0.6 (linked to an older PostgreSQL 7.2 client library)
running simultaneously, connecting to the very same DBs, but it hasn't 
had the same connection problems.

I was wondering if it might be something with psycopg and the new pgsql 
8.0.1 library.  What pgsql client lib is you psycopg linked to?

Re: Potential PythonScript bug (was: Re: [Zope] question about manipulating zcatalog query results)

2005-04-04 Thread Ira Sher
Dieter,
thanks. I'll take a look at that now. The folks at bug collection are
unable to reproduce the bug on 2.7.5, though, and so we're trying to
determine how else it might be occuring--Products would be my best
guess, as the Product list has changed (many are obsolete or simply
don't run on 2.7.5 when migrating from 2.5.1 (with products that have
been left on since 1.x...ug). The last version I had it running stably
on was 2.6.3, locally, and of the several products that have been
migrated out since then, PluginIndexes and ZCTextIndex I can't grab
from cvs (the versions I have crash the startup) as I get a 4k empty
tarball downloading with any browser...don't know if these should be
obsolete, too.

take care and thanks again for the suggestions
ira

 This doesn't work, either, in zope 2.7.4 or 2.7.5 with python 2.3.4
 and 2.3.5 respectively, as far as I can see.
 
 Thanks for taking a look at things--I'll file a bug report (this is
 stopping me from migrating a site into 2.7) as you suggested
 
 The strange thing is that I can do:
 
 return [o.id for o in container.Catalog()]
 
 without a problem.
 
 However, I am still using Zope 2.7.2 -- the version
 before the last security shakeup...
 
 If your script does not need security checks, than
 my TrustedExecutables might help you. It provides
 PythonScripts without any security restrictions -- and
 especially without the need for _getiter_.
