I have to explain a bit that you can understand the problem. Zope's request processing has roughly two phases: URL traversal to locate the object identified by the URL and then calling the located object. At the end of URL traversal lies the user authentication. This proceeds as follows: Zope starts at the located object and looks upward (towards to root) to find a User Folder which is ready to authenticate the user with the required roles. It will ask each User Folder it finds above the object until one gives a positive answer. The highest user folder will always return a user, maybe the anonymous one. If your User Folder calls out to a backend system and this backend system calls back (via URL) into an area controlled by your User Folder, then you lose -- as the User Folder will again call out and wait for an answer before it will call the object... Move the thing called back out of your hiararchy dominated by the UserFolder. Then, you might have success. -- Dieter

Thank you Dieter! Here is the exact scenario, which in I first observed the problem: I have a external zope python module that communicates via TCP with a background system written in Java. I have a background system that communicates with the Zope via URL. I have a demo user folder in my Zope project with two scripts. The first script sends a tcp message to the background (with the help of external module), the second one do something when the background call it via url. First the Zope script sends a tcp message to background system, and waits for the reply. The background receives the message and try to call the url by http request, then if it is success replies to Zope script's tcp request. Here is the problem. The background system cannot access the URL until in the first script tcp timeout happen. When I move the second script into other outer folder, all is OK. It is very strange, and I'v never read from this problem before.

I had to fix a problem in "psycopg": During "connect", Python's Global Interpreter Lock (GIL) was not released (freezing Zope during connect). Usually, this is not a problem as "connect" is quite a fast operation. We noticed it only when the server for the postgres installation was down (then "connect" became a several minute operation until the TCP timeout happened). However, it is unlikely, that this is your problem. >The behaviour is the same when i >use long socket communication (as a tcp client), etc. This, too, should not happen -- and I never observed it (but a colleague reported something like this but never showed it to me -- and I did not believe him; or more precisly, I tested his alledgedly observed behaviour and could not reproduce it...) >In these cases the >folder wich contains the scripts be unaccessible. Unbelievable -- unless your folder access triggers the long socket communication. In this case, it would not be the old socket communication that "blocks" but the new one. Of course, your folder access should not trigger anything else... -- Dieter

Hi Dieter! Than you for your answer! I use the same product. This problem is one of the others... The behaviour is the same when i use long socket communication (as a tcp client), etc. In these cases the folder wich contains the scripts be unaccessible. Maybe have i a wrong zope configuration (i use default config)?

You might be using an unfortunate Postgres adapter library. We are using "psycopg" and do not observe this problem. -- Dieter

idiotic dreamweaver question
by David Bear 21 Sep '06

21 Sep '06

Sorry to bug this list with a dw question. However, I was using DAV in dw and found that dw is unable to handle file extensions like .pt, .zpt, _html , etc. Does anyone else use dreamweaver to edit zope/plone files? If so, how do you make dreamweaver edit this types of files? I know _html, .pt, .zpt etc are well formed xhtml -- but I don't know how to tell stupid dw to edit them since it uses the extension to recognize file type. -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"

Zope 2.10b2 build issue
by Pascal Peregrina 21 Sep '06

21 Sep '06

Hi, Just to let you know that if you use a temporary build directory to build Zope 2.10, the setup.py script fails. I know, I am using python 2.5 (making some tests) but this issue is unrelated. Below, "build" is an empty directory and "src" is the untared Zope source. STEP 1 cd build/Zope-2.10.0-b2 && /opt/pperegri/F2BUILDS/F2.15/src/Zope-2.10.0-b2/configure --prefix=/opt/pperegri/F2BUILDS/F2.15/opt/Zope-2.10.0-b2 --optimize --with-python=/opt/pperegri/F2BUILDS/F2.15/opt/Python-2.5/bin/python Using Python interpreter at /opt/pperegri/F2BUILDS/F2.15/opt/Python-2.5/bin/python Configuring Zope installation - Zope top-level binary directory will be /opt/pperegri/F2BUILDS/F2.15/opt/Zope-2.10.0-b2. - Distutils install flags will be "--optimize=1 --no-compile" - Makefile written. Next, run make. => OK (generates makefile in the build directory) STEP 2 "/opt/pperegri/F2BUILDS/F2.15/opt/Python-2.5/bin/python" "/opt/pperegri/F2BUILDS/F2.15/src/Zope-2.10.0-b2/setup.py" \ build --build-base="/opt/pperegri/F2BUILDS/F2.15/build/Zope-2.10.0-b2/build-base/p ython-2.5" --build-lib="/opt/pperegri/F2BUILDS/F2.15/build/Zope-2.10.0-b2/build-base/py thon-2.5/build-lib" --build-scripts="/opt/pperegri/F2BUILDS/F2.15/build/Zope-2.10.0-b2/build-bas e/python-2.5/build-scripts" --build-temp="/opt/pperegri/F2BUILDS/F2.15/build/Zope-2.10.0-b2/build-base/p ython-2.5/build-temp" => FAILURE: Traceback (most recent call last): File "/opt/pperegri/F2BUILDS/F2.15/src/Zope-2.10.0-b2/setup.py", line 53, in <module> import versions ImportError: No module named versions make: *** [build] Error 1 CAUSE: The problem comes from this code in setup.py (which did not exist in Zope 2.8): sys.path.insert(0, 'inst') import versions del sys.path[0] ZOPE_VERSION = '%s%s-%s' % (versions.ZOPE_MAJOR_VERSION, versions.ZOPE_MINOR_VERSION, versions.VERSION_RELEASE_TAG) If I change it to: try: MAKEFILEDIR = os.path.dirname(os.path.abspath(__file__)) except: MAKEFILEDIR = os.path.dirname(os.path.abspath(sys.argv[0])) sys.path.insert(0, '%s/inst'%MAKEFILEDIR) import versions del sys.path[0] ZOPE_VERSION = '%s%s-%s' % (versions.ZOPE_MAJOR_VERSION, versions.ZOPE_MINOR_VERSION, versions.VERSION_RELEASE_TAG) Everything works fine.

My system is a developer server so i'm the only one who use the zope. When i run the script there is not other worker script. I'm newbie but i read that there is a tool named zasync that maybe solves my problem but i cannot install it yet. I would like solve my problem without this if possible.

Hello, We're currently not using ZEO, but may do so in the future. Question is, do we need to export or convert our Data.fs to a ZEO-capable format ? Regards, Danny

PageTemplate i18n migration from Zope2 to Zope2+Five / Zope3...
by Pascal Peregrina 20 Sep '06

20 Sep '06

Hi, I would like to know the right way to manage messages and store them in ZODB with Zope2+Five or Zope3. Currently, in Zope2, I use Localizer MessageCatalog objects. Is there a new way already available through Five? (note that I don¹t want to use flat files for translations, they must be ZODB stored for my use case) Thanks.
