Help with virtual hosting Zope on different ports
by Michael Sanborn 20 Sep '05

20 Sep '05

I have two Zope versions running behind Apache 1.3 (on FreeBSD 4) using different ports on the same server. The only domain name currently assigned to the server is for a Squishdot site on the older Zope version (2.5.1) that I haven't been able to upgrade, and I don't want to spend the time figuring it out right now. The newer Zope version (2.8.1) has a Plone site that I would like to run as a domain of its own. Can someone help me figure out the combination of Apache rewrite rules and Zope/Plone products I would need to use to accomplish this? Just to try to make it clear, what I want is: request: oldsite.com result: myserver:8093/oldsite request: newsite.com result: myserver:8580/newsite This is possible, isn't it? If it helps, here are the existing rewrite rules: <VirtualHost oldsite.com> ServerName oldsite.com ServerAdmin webmaster(a)oldsite.com DocumentRoot /u2/oldsite ScriptAlias /cgi-bin/ /u2/oldsite.cgi-bin/ RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/(oldsite/)?(.*) /usr/local/Zope/Zope.cgi/oldsite/$2 [e=HTTP_CGI_AUTHORIZATION:%2,t=application/x-httpd-cgi,l] ErrorLog /u2/oldsite.admin/oldsite.errors TransferLog /u2/oldsite.admin/oldsite.access </VirtualHost> <VirtualHost www.oldsite.com> ServerName www.oldsite.com ServerAdmin webmaster(a)oldsite.com DocumentRoot /u2/oldsite ScriptAlias /cgi-bin/ /u2/oldsite.cgi-bin/ RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/(oldsite/)?(.*) /usr/local/Zope/Zope.cgi/oldsite/$2 [e=HTTP_CGI_AUTHORIZATION:%2,t=application/x-httpd-cgi,l] ErrorLog /u2/oldsite.admin/oldsite.errors TransferLog /u2/oldsite.admin/oldsite.access </VirtualHost> Thanks in advance for any assistance, Michael Sanborn

RewriteRule Witch
by Sascha Welter 19 Sep '05

19 Sep '05

Hello Zopistas! Virtual hosting with Zope usually involves setting up Apache "in front" of Zope, putting a Virtual Host Monster into your Zope Root and configuring some RewriteRules in your httpd.conf. Since I don't do this every day (like most zopistas, I guess), every time I have to dig up my knowledge of rewrite rules again from almost scratch. Now I wrote a little script to help me with the most frequent cases of those RewriteRules. You can try out the Rewrite Rule Witch online: http://betabug.ch/zope/witch Please note that there might still be bugs and mistakes in there. I'm happy to receive feedback about this thing. Especially interesting would be to try out some of the configurations you have and see if the result is what you actually use. I cover only the most basic variants, but likely the ones used for 95% of Zope setups. I do not yet cover rewriting "/manage" URLs to https (next project!) Regards, Sascha

"TestODBCEM" is an external method that uses a python module with a function named "TestODBCEM". This function uses the parameters sysDSN, usr, mypass, sSQL to connect to the sysDSN with user name usr, password mypass and execute sSQL query. After that it returns the results witch i show in a table. --- Tino Wildenhain <tino(a)wildenhain.de> wrote: > Thomas Apostolou schrieb: > > Hello all, > > i use the following to get to show the results > from an > > sql query. > > What are the expresions to show the field names? > > > > <table> > > <dtml-in expr="TestODBCEM(sysDSN=sysDSN, > usr=usr, > > mypass=mypass, sSQL=sSQL)"> > > <dtml-if sequence-even> > > <tr bgcolor="lightgreen"> > > <dtml-else> > > <tr> > > </dtml-if> > > <dtml-in sequence-item> > > <td><dtml-var sequence-item></td> > > </dtml-in> > > </tr> > > </dtml-in> > > </table> > > > > See: > http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/RelationalDatab… > > particulary result.data_dictionary() which gives > you the names of the columns. > > I'm not sure what you mean with the DSN in your > example above. > For me it does not look correct.

Text field and module import questions
by Ivan Stout 19 Sep '05

19 Sep '05

Greetings, It appears that the text input field I have created using a dtml method has a default space character when you click in the field. Is there a way to get rid of this? Also, I have a python script that I would like to import a python module, but when I run it Zope complains the user does not have authorization. Is there a way around this? Thanks. Ivan

I've found where this topic is covered in "The Definitive Guide to Plone" (pp. 292-303) and have installed Virtual Host Monsters in both Zope instances. I still have some questions about how to edit httpd.conf, but since that's just an Apache issue, I'll sign off with a "Neverrrr Minnnnd..."

Character set problems
by Niklas Saers 17 Sep '05

17 Sep '05

Hey guys, I've installed Zope on a FreeBSD server. My problem domain is very small: display a list of when people are unavailable, and let people update the list. This is all in Danish, and here are come my problems. Danish has three extra letters not in the ASCII alfabet, three upper-case and three lower-case. When getting the data from a <input name="test" /> where I've written "æ ø å Æ Ø Å", I get: Ã¦ Ã¸ Ã¥ Ã† Ã˜ Ã… What is the standard way of ensuring that I get the correct data? I tried writing a little converter, but the string tekst = tekst.replace("\xc3\xa6", "ae"); gives me the error *UnicodeDecodeError: **'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)* Do you have any suggestion on how to overcome these problems? Cheers Nik

High Traffic Zope Portal

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We use zope with the following environment: - - Zope 2.7.4-0 - - ZCoMIX-1.0.2+ (http://sourceforge.net/projects/zcomix) - - mysqlUserFolder 1.0.0 - - python 2.3.4 - - Red Hat Enterprise Linux ES release 2.1, kernel 2.6.11, ext2 fs - - MySQL-server-4.0.20 - - Apache 2.0.50 (with HTTPS) for cache 1 Portal replicated through Zeo and balanced with DNS Round Robin.

The document is generated using queries in MySql database, after user autentication using mysqluserfolder. The python processes occupied 100% of machines resources (cpu and memory), and the load average increased quickly. We evidenced that the problems had occurred before user authentication, only trying access the initial page of the Zope portal. We estimated that the simultaneous accesses to our portal are approximately 10000 people in a moment, that finished generating a DoS (Denial of Service) in our portal. To resolve the problem momentarily, we posted static documents in PHP, without Zope. Have someone experience in sites of great traffic using Zope? If so, please give us some tip for tunning the system or discover the bootleneck points. We have doubts if what it is generating the problem is the ZCoMIX or the Zope, or even though the configuration of Apache. - -- Jeronimo Zucco LPIC-1 Linux Professional Institute Certified Núcleo de Processamento de Dados Universidade de Caxias do Sul "May the Source be with you." - An unknown jedi programmer. http://jczucco.blogspot.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFDKwphTCq0VJ4DIPwRAoCWAJ9ILkzxHiCNKd3Uq9Y8T+Gi/YmopQCgjPY/ ytXv2M1K7rZ2EgzDEbpJtVI= =8sTe -----END PGP SIGNATURE-----

Zope 3.1.0 RC 3 released!
by Stephan Richter 16 Sep '05

16 Sep '05

The Zope 3 development team is proud to announce Zope 3.1.0 candidate 3. Zope 3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. It is in our opinion that Zope 3.1 is more than ready for production use, which is why we decided to drop the 'X' for experimental from the name. We will also continue to work on making the transition between Zope 2 and Zope 3 as smooth as possible. As a first step, Zope 2.8 includes Zope 3 features in the form of Five. Now that we have a release that we would like to declare stable next week, we are looking for translators, who translate Zope 3 into their favorite language! We are utilizing the Rosetta system from Ubuntu for managing those translations. If you are not familiar with Rosetta, please send us a mail to zope3-dev(a)zope.org and we get you set up. Downloads http://zope.org/Products/Zope3/ Installation instructions for both Windows and Un*x/Linux are now available in the top level 'README.txt' file of the distribution. The binary installer is recommended for Windows. Zope 3.1 requires Python 2.3.5 or 2.4.1 to run. You must also have zlib installed on your system. Changes Since 3.1.0c2 - Fixed several bugs that were considered critical. * Ported Stuart Bishop's work in ``pytz`` and ``zope.i18n`` to address broken and misleading timezone code (i.e., one issue was broken and another was misleading). * Fixed apidoc to handle extended paths, so that zope packages could be installed in software instances without apidoc losing knowledge of the core zope code. * Added custom ``executemany()`` method for cursors created through GadflyAdapter. See http://www.zope.org/Collectors/Zope3-dev/445 for discussion. - Updated ZODB to 3.5.1b2. Most Important Changes Since 3.0 - New Pluggable Authentication Utility (PAU), which is similar in philosophy to the Zope 2 PAS. The following features are available in the in the basic PAU facility: + Credentials Plugins: Basic HTTP Auth, Session + Authenticator Plugins: Principal Folder, Group Folder For a detailed description of the pluggable authentication utility, see 'zope/app/authentication/README.txt'. - Major simplifications to the component architecture: + Removal of the concept of a service. All outstanding services were converted to utilities: Error Reporting, FSSync, Authentication. + Site Managers are global and local now; adapters and utilties are directly registered with the site manager. Now global and local component registration and lookup behaves very similar. + Local registrations can now only have two states: active and inactive. This simplified the code so much, that 'zope.app.utility', 'zope.app.registration' and 'zope.app.site' were all merged into 'zope.app.component'. + Implemented menus as utilities. The API also supports sub-menus now. + Implemented views as adapters. Skins and layers are now simply interfaces that the request provides. - Added an integer-id facility for assigning integer identifiers to objects. - Added basic catalog and index frameworks. - Added "sources", which are like vocabularies except that they support very large collections of values that must be searched, rather than browsed. - Created a new granting UI that allows advanced searching of principal sources. - Implemented a generic user preferences systsem that was designed to be easily used in TALES expressions and via Python code. Preferences can be edited via 'http://localhost:8080/++preferences++/'. A demo of the preferences can be found at:: http://svn.zope.org/Zope3/trunk/src/zope/app/demo/skinpref/ - ZCML now supports conditional directives using the 'zcml:condition' attribute. The condition is of the form "verb argument". Two verbs, 'have feature' and 'installed module' are currently implemented. Features can be declared via the 'meta:provides' directive. - Improved API doctool: Code Browser now shows interfaces, text files and ZCML files; the new Book Module compiles all available doctext files into an organized book; the new Type Module lets you browser all interface types and discover interfaces that provide types; views are shown in the interface details screen; views and adapters are categorized into specific, extended and generic; user preferences allow you to customize certain views; 3rd party modules can now be added to the Code Browser. - Improved I18n-based number and datetime formatting by integrating 'pytz' for timezone support, implementing all missing format characters, and reinterpreting the ICU documentation to correctly parse patterns. - Added '++debug++' traversal adapter that allows you to turn on debugging flags in 'request.debug'. Currently the following flags are defined: source, tal, errors. - Improved logout support. - Added the HTTP request recorder, which lets you inspect raw HTTP requests and responses. It can be used to create functional doctests without requiring third-party tools such as TCPWatch. - Developed a generic 'browser:form' directive. It is pretty much the same as the 'browser:editform' directive, except that the data is not stored on some context or adapted context but sent as a dictionary to special method (by default). For a complete list of changes see the 'CHANGES.txt' file.

Installing Python Modules Under Zope On Windows
by tom＠tompurl.com 16 Sep '05

16 Sep '05

I have a hardware constraint where I have to run Zope on Windows. This has worked pretty well for me because Zope 2.7 used my "system" instance of Python 2.3.x. At least, that's my assumption since runzope.bat pointed at the system instance of Python. This setup was nice because it made it very easy to install Python modules (like PIL). When I ran the module installation executable, it would find my system instance of Python in the registry and install the module properly. With Zope 2.8.1, the "default" setting seems to be using the embedded Python interpreter that came with Zope. This is a problem because the embedded versions of Python do not appear in the registry, making it impossible to install a lot of Python modules on Windows. I thought that the following script (http://effbot.org/zone/python-register.htm) would allow me to add embedded versions of Python to my registry. However, you can't add more than one major version of a python release (2.2, 2.3, etc) to the registry. So if my system version of Python is the 2.3.x branch, and I want to use an embedded 2.3.x version of Python with Zope, then I'm out of luck if I want to install many Python modules with it. I can still edit runzope.bat so that it points at the system instance of Python, but I don't know if this is a best practice. Has anyone had any luck installing Python modules in an embedded version of Python on Windows? Is there a better way to work around this than referencing the system version of Python in the runzope.bat file? Thanks in advance for any help! Tom Purl
