Conversion from unix date
by Ed Colmar 05 Mar '04

I'm sure this has been asked before, but I couldn't get any search hits. Hopefully someone could point me in the right direction. I have a date field that looks like 1076754860 How can I convert this out to a regular date? Thanks -ed- -- Green Graphics ::: Print and Web Design ::: 510.923.0000

Zope 2.6.4/2.7 Slow FTP...again.
by Edward Pollard 05 Mar '04

05 Mar '04

While we're working on trying to find alternate solutions, we've decided to go back to Zope 2.6.0 to serve the data in the system we've developed over the last year and a half. We took a box, running RedHat 9, and installed Zope 2.6.0 as follows: Install directory: /usr/local/zprod python: # export CC="gcc -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/kerberos/include" # ./configure --prefix=/usr/local/zprod/python --with-threads # make # make install Zope: # cd /usr/local/zprod # tar -zxvf /web/zsup/src/Zope-2.6.0-src.tgz # mv Zope-2.6.0-src Zope-2.6.0 # ln -s Zope-2.6.0 zope # chown -R apache:zopeadmins Zope-2.6.0 # cd zope # su apache -s /bin/sh -c "/usr/local/zprod/python/bin/python2.1 ./wo_pcgi.py" # /usr/local/zprod/python/bin/python2.1 ./zpasswd.py inituser and testrun: # su apache -s /bin/sh -c "./start" Works like a charm. We used the exact same steps for Zope 2.6.4. FTP downloads run at 10k/sec. Anyone see any problems with this? Anyone else using RedHat 9? We're going to try an install on Debian tomorrow. Ed

SFTPGateway problems
by Brad Clements 05 Mar '04

05 Mar '04

Mostly for fdrake.. FYI, Twisted 1.20 has serious issues with the ftp client. For example, the LIST command is sent as L\nI\n etc.. (looks like a tuple unpack error). I checked out Twisted from CVS and that fixes the List command, but it still doesn't work correctly with sftpgateway. Using an sftp client, or jEdit's FTP client plugin, I can list files but RETR returns nothing. I went back to Twisted 1.1.1 (this is all on Python 2.3) and now sftp seems to work (at least RETR does), but the jEdit FTP plugin cannot download a file. I see this for debug output: 2004-03-05 11:37:38 sftpgateway.bkc:3 FTP command: PASV 2004-03-05 11:37:38 sftpgateway.bkc:3 FTP message: 227 Entering Passive Mode (127,0,0,1,223,245) 2004-03-05 11:37:38 sftpgateway.bkc:3 FTP command: RETR /Holmes/BottomNavBar.pt 2004-03-05 11:37:38 sftpgateway.bkc:3 connection lost 2004-03-05 11:37:38 sftpgateway.bkc:3 received chunk for offset 0 (1531 bytes) 2004-03-05 11:37:38 sftpgateway.bkc:3 FTP message: 150 Opening Binary mode data connection for file '/Holmes/BottomNavBar.pt' 2004-03-05 11:37:38 sftpgateway.bkc:3 FTP message: 226 Transfer complete 2004-03-05 11:37:38 sftpgateway.bkc:3 FTP command: QUIT 2004-03-05 11:37:38 sftpgateway.bkc:3 FTP message: 221 Goodbye. 2004-03-05 11:37:38 sftpgateway.bkc:3 lost FTP connection: connection lost However the jEdit plugin works fine with the standard Linux sftpd. I can't see why jEdit would drop the connection. From the client side, it's still waiting to receive data. jEdit uses the open source sshtools stuff from sourceforge. My question is, has anyone gotten jEdit to work with sftpgateway? And warning, if you move beyond Twisted 1.1.1 be ready for some debugging. :-( -- Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax http://www.wecanstopspam.org/ AOL-IM: BKClements

FTP server
by John Poltorak 05 Mar '04

05 Mar '04

Does Zope's builtin FTP server automatically start up when starting Zope? It doesn't appear to start for me unless it is using some port I don't know about. Is there anything in the build options which specify that it should start up automatically, and which port it should use? Or any logs which might tell me that it did start but failed? -- John

inside-out virtual hosting
by Erik Myllymaki 05 Mar '04

05 Mar '04

The last section of this page, http://zope.org/Documentation/Books/ZopeBook/2_6Edition/VirtualHosting.stx , describes what I am hoping to accomplish. I can setup p virtual hosting with VHM where zope is the default and selective folders are static content served by apache, but I want to do the opposite. I want 90% of the site to sit in /var/www/htdocs and be served by apache and just some of the content via Zope - going to www.mydomain.tld should bring up the static index.html file, and only going to www.mydomain.tld/Zope/* would bring up zope dynamic content. Can anyone explain this in better detail? The article is fairly vague...

Urm, yeah, well, you'll need ot Zope source and binary code to be able to execute the Zope source and binary code ;-) You're currently trying to drive a car with fuel and no car ;-) You need to build an image which contains a Zope 2.7.0 install, and a Zope 2.7.0 instance home which uses that install, and make damn sure neither does anything to write to disk... cheers, Chris

Re: [Zope] Server Spontaneously Quitting
by Murray Pearson 05 Mar '04

05 Mar '04

I'm trying to figure out where the failing is for the Apache server config. What exactly is meant by the Bad Gateway error? In what way is Zope's response invalid? Is there some place I can look to get a more detailed traceback-type error report? Some possible clues: [Thu Mar 04 13:30:50 2004] [warn] _default_ VirtualHost overlap on port 80, the first has precedence This line spits out several times when Apache starts and also after apachectl configtest. I noticed in the Zope Book that Apache 2 needs the proxy_http module so I added that as well (statically compiled it in). I still have the simple virtual hosts inside the Virtual Host Monster. Will that be confusing the issue? Shall I delete the mappings? (I'll try that next.) ....Nope, that didn't fix it either. ( My apologies if this is a double post )

"Undo changes" strange behaviour of permission propagation
by robert rottermann 05 Mar '04

05 Mar '04

Hi there, This is with Zope 2.62 I want to offer Plones "Quick undo" to a user only in some parts of a site. When I test for the right whether he is allowed to "Undo chages" with the following test that checks what roles are allowed a permission [ s for s in map(lambda x : len(x['selected']) and x['name'], context.rolesOfPermission('Undo changes')) if s] I do not get the inherited roles but only the ones assigned to the folder I perform the test on. If I do the same for "View" I get also the inherited permissions. Should not rolesOfPermission also return the inherited roles ? Robert

Permission-problem or bad design?
by Petter Holmström 05 Mar '04

05 Mar '04

Hello list, I've run into a rather interesting design problem that I don't know how to solve. I'm creating a group calendar (in Plone). There are two kinds of event objects, an Event object and an Event Reference object. They are used in the following way: Person A organizes a meeting to which he invites persons B and C. He then creates an Event object i his calendar and Event Reference objects in B's and C's calendars. The Event Reference contains all the fields of the event object (marked as read-only) plus two editable fields, one reference field to the original event object and a boolean field (accept/reject). Both the event objects the reference objects use the same view-page. So far no problems. Now every event can be either public, semi-public ("busy") or private. This means that even though A has marked the event as semi-public, B and C must have full read-rights to the event. What's more, if B marks his reference as public, visitors must be able to get full read-rights to A's event through B's event reference. I've figured I'd need some kind of object-based security and not user-based, i.e. instead of giving the B-user rights to A's event I'd give the B-user's event rights to A's event. Phew. This sure sounds complicated. :-) Perhaps some ascii-art will make it clearer: [A's calendar] | +--- Base Event <-+------+---(busy)------> anonymous user *) | | (public) | [B's calendar] | | | | | +--- Reference >--+------|---(public) ---> anonymous user **) | (public) [C's calendar] | | | +--- Reference >---------+---(private) --> anonymous user ***) *) Anonymous user has limited rights to A's base event. **) Anonymous user has full read rights to B's reference, which gets its data from A's base event, to which the anonymous user has limited rights. ***) Anonymous user has no rights at all to C's reference. I really don't know how to achieve this with the current security model of zope. Is there a better way to solve this problem? Did you even understand my dilemma? Thanks, -Petter-
