Uploading an object's content via FTP
by Gilles Lenfant 05 Jul '02

05 Jul '02

Hi, I made a CMF portal_type class based on python product. This contains a Photoshop file and some dedicated related services. Users may upload Photoshop files via HTTP. This works with small files but when a user uploads a big file (8 Mb and more) through HTTP, this stalls the server. So I need to provide the user an alternate way to upload the object's content with an FTP client. Where should I start to get this working ? Examples somewhere ? How can I programmatically know the port number for Zope FTP ? How can I catch "FTP upload complete" event ? Thanks in advance. --Gilles

Re: [Zope-CMF] i18n for CMF And Plone, backporting i18n to Zope 2.x
by Sidnei da Silva 02 Jul '02

Hi Robert, My friend Lalo (lalo(a)laranja.org) started a rewrite of TAL to make it more pluggable and ease backporting of i18n to Zope2. I dont know how much if it is done right now, but the last time I talked to him, he said that only METAL was missing. His work is available at http://sf.net/projects/collective -> Browse CVS -> Alt-TAL module. I think that the best idea is support him, as he has almost everything in place.

Write in a file.
by Juliette Colmant 01 Jul '02

01 Jul '02

Hello, I have a Python script that has to write a "string" in a file. When I launch it from Zope, I have an error message from Zope telling me I can't write in my file. Is there a way to write in a file from Zope or not? Is that a problem a rights? Do I change something about the security in Zope?

I looked a few weeks ago, and it's deep in the C code, and grep-proof besides :-) Look in ZODB/cPersistence.c, grep for "'m'" (with single quotes). My conclusion was that it was very tied to the ZODB and that setting it would probably break the serial or transaction mechanisms.

Note that in most projects, people now deal with an explicit 'modication_date' or 'modification' property like you suggested. But this requires setting it whenever the object changes.

locking bug?
by Andreas Lauser 28 Jun '02

28 Jun '02

Hi list. When an object locked via WebDAV (i.e. the external editor) and you copy this object using the ZMI, the copied object ist also locked. This makes it impossible to modify it for some time. I doubt that this is a feature, but you never know... mfg AND -- I doubt, therefore I might be.

Hi all, I want to learn more about caching in Zope on Database side and on CacheManagers. Is there corelation between performance and caching via Database Cache Parameters and StandardCacheManagers ? I need a guide thru optimization of performance using the right cacheung technic. Regards, Dirk

error with libraries that I'm not using anymore
by Juliette Colmant 27 Jun '02

27 Jun '02

Hello, I have a problem using libraries in Zope. I have a Python script that calls a C++ code using libraries. Actually, at the begining I had a test.so library. But now I changed the way to compile my program and I have no test.so library anymore, and when I call my python script via Zope, I have this message : Error Type: ImportError Error Value: test.so: cannot open shared object file: No such file or directory But I don't use the test.so anymore. And when I use the python script alone without Zope it runs whitout any problem! I tried to change the name of my external method to see if it was not a problem of cache but I have still the same problem... Does someone have an idea?

problem using C++ code called by Python in zope
by Juliette Colmant 27 Jun '02

27 Jun '02

Hello, I have a problem using C++ code called by Python in zope. I have a python script that calls a C++ code. When I just use the python script without zope, I can see the messages I printed in the C++ with the "cout" command, but when I call the script via Zope, I can't see these C++ "cout" message anymore! When I print things in my Python scripts using the python "print" i can see them but nothing happends with the C++ "cout"... Does someone know if there is a way to see them? Thanks Juliette. ___________________________________________________________ Do You Yahoo!? -- Une adresse @yahoo.fr gratuite et en français ! Yahoo! Mail : http://fr.mail.yahoo.com
