I think the first problem will be finding a publisher that streams. PCGI buffers all I/O, perhaps FastCGI doesn't. Even if you didn't, sending it through Zope in chunks would avoid getting Zope's memory footprint up there. One way would be to have the ExternalMethod return a sequence, then do something like:    Of course the above might be completely wrong, but you get the drift :^) --Paul

Mailhost problems.
by Jose.Lacal＠icn.siemens.com 10 Mar '99

10 Mar '99

Folks: I am still stuck with a sendmail / Mailhost problem. Everything works fine except mailing from a DTML document via sendmail.   I am using: Red Hat 5.2 Zope 1.10.2 - I created a username of "zope_u" and a group "zope" - I did run the installation script with a command line like: ./install -sAdmin:MyPassword -u zope_u -g zope - I created the Feedback and SendFeedback forms as per the manuals. - I added the user "zope_u" to the mail group. - I modified user zope_u's .bash_profile file to include the path to sendmail in /usr/sbin - If I log-in to the Linux server as zope_u, I _am_ able to call sendmail and to send mail outside of the server. Anything else I missed, folks? Regards.

ZSQL methods in parent subfolder
by John Eikenberry 10 Mar '99

10 Mar '99

Is this behaviour a bug? I have all my ZSQL methods collected together in a folder. If I call these from a sibling folder[1] without any arguments, ie.  I get the below error, if I call them with specific arguments, ie.  I get no errors. (comp_id was in REQUEST in both cases). [1] by sibling folder I mean something like the following arrangement... /sql/company (where the sql method is stored) /lists/company_list (where the call is made) Here's the error:  Traceback (innermost last): File lib/python/ZPublisher/Publish.py, line 877, in publish_module File lib/python/ZPublisher/Publish.py, line 590, in publish (Info: /filter/contacts/index_html) File lib/python/OFS/DTMLDocument.py, line 212, in __call__ (Object: index_html) File lib/python/OFS/DTMLDocument.py, line 208, in __call__ (Object: index_html) File lib/python/DocumentTemplate/DT_String.py, line 513, in __call__ (Object: index_html) File lib/python/DocumentTemplate/DT_In.py, line 656, in renderwob (Object: sql.companies) File lib/python/Shared/DC/ZRDB/DA.py, line 420, in __getitem__ (Object: CopySource) File lib/python/Shared/DC/ZRDB/Aqueduct.py, line 332, in __getitem__ KeyError: (see above) Looking into it, line 332 in Aqueduct.py is a simple key lookup... def __getitem__(self, key): return self._data[key] It would seem that an argument is getting passed in by default when the sql in put in a parent's subfolder. --- John Eikenberry [jae(a)kavi.com - http://taos.kavi.com/~jae/] ______________________________________________________________ "A society that will trade a little liberty for a little order will deserve neither and lose both." --B.

streaming data through zope from an external method.
by Anthony Baxter 10 Mar '99

10 Mar '99

I've got an external method that is generating a (possibly quite large) audio file and sending it back. Right now, I'm generating this in memory in a big string, then returning it to zope. I'd _like_ to be able to just have the external method send the data straight through (maybe in chunks) without having to read it all into memory. Is this possible with zope at all? Anthony

Apache Authorization

Hi, I cannot go to management screen of Zope, probably due to some problem with Apache. http://www.sol.cz/cgi-bin/Zope.cgi, if someone would care to look at it. Thanks! -- Milos Prudek

ZPyGreSQL Database Connection Problem
by William Whitehead 10 Mar '99

10 Mar '99

I just installed the updated version of PostgreSQL 6.4.2 on Linux 2.2.2. I was able to compile and add the ZPyGreSQL Product to my Zope installation. I want to create a Database connection. When I go to create a new one, it asks for the Id, Title, and Database Connection String. What do I put into the Database Connection String? I tried the database I want to use, but it gives Invalid connection String: baseball Is it a rights issue with PostgreSQL or something else? What is it expecting the database connection string field anyway? Thanks for your help!

Another "no such file" failure...
by Mike Meyer 10 Mar '99

10 Mar '99

I'm trying to get zope working to study it, but keep stumbling over the "(102) failure during connect" error - with the "No such file or directory" addendum. The underlying OS is FreeBSD 3.1. I want to run it on an Apache web server (at least for now), with the server doing the authentication. That all appears to be working properly - after all, I'm getting errors from pcgi, now, right? The var directory is writable by nobody. In fact, the entire source tree is owned by nobody, which is the user that the Apache httpd is running as. However, I get log file entries from pcgi, even after deleting the pcgi.log file. I initially tried copying the Zope.cgi file to cgi-bin, but noticed that some (unspecified) setting in Zope.cgi might need to change because of that, so I added a second scriptalias to the Apache httpd.conf pointing at the source directory, set the protections on it, and tried to load <URL: http://localhost/Zope-bin/Zope.cgi/manage >. No change - the log file records the same error message. The pcgifile.py test reports error attempting: 'from cgi_module_publisher import publish_module' This doesn't appear to exist in the distribution - and I recalled something about that being a holdover from bobo, so I removed that test from the script, and ran it again. The modified version runs cleans. Was I wrong about cgi_module_publisher? Should it be finding that? If not, then what's the next thing to look at? FWIW, here's the entry from httpd.conf section for Zope: SriptAlias /Zope-bin/ "/home/mwm/external-src/Zope-1.10.2-src/" <Directory "/home/mwm/external-src/Zope-1.10.2-src/"> AllowOverride None Options None FollowSymLinks Auth_PGhost sql Auth_PGport 5432 Auth_PGdatabase web Auth_PGpwd_table users Auth_PGuid_field name Auth_PGpwd_field password Auth_PG_encrypted off AuthName "Zope" AuthType basic require valid-user </Directory> And here's Zope.cgi: #!/home/mwm/external-src/Zope-1.10.2-src/pcgi/pcgi-wrapper PCGI_NAME=Main PCGI_MODULE_PATH=/home/mwm/external-src/Zope-1.10.2-src/lib/python/Main.py PCGI_PUBLISHER=/home/mwm/external-src/Zope-1.10.2-src/pcgi/pcgi_publisher.py PCGI_EXE=/usr/local/bin/python PCGI_SOCKET_FILE=/home/mwm/external-src/Zope-1.10.2-src/var/pcgi.soc PCGI_PID_FILE=/home/mwm/external-src/Zope-1.10.2-src/var/pcgi.pid PCGI_ERROR_LOG=/home/mwm/external-src/Zope-1.10.2-src/var/pcgi.log PCGI_DISPLAY_ERRORS=1 BOBO_REALM=Zope BOBO_DEBUG_MODE=1 INSTANCE_HOME=/home/mwm/external-src/Zope-1.10.2-src Thanx, <mike

Thanks for your help, Pavlos. I found another way. Instead of writing:  I wrote this, and it worked fine:  I found a way, but I don't understand why the first syntax worked fine with Folders and fails with DTML Documents. If anyone would like to clarify the semantic difference between _['sub-document'] and _.getitem('sub-document'), I would be even happier. By the way, Pavlo's site http://www.gaaros.com:9673/ is useful! []s Luciano

I understand the difference between DTML Methods and DTML Documents. The very reason I chose to do it with DTML Documents was to be able to store some special fields, such as 'author' in my example, along with the document. I cannot do that with DTML Methods, as they do not have properties. In Zope 1.0.9 I used folders but I was running into problems with relative links. It seemed natural to switch from my previous folders to the new DTML Documents. I still do not know to reference the properties of a DTML Document 'A' from within a document or method 'B' in located in the same folder as 'A'. Thanks for any help. []s Luciano
