Restriction on file upload sizes on Zope.org
by Martijn Pieters 28 Aug '01

28 Aug '01

Hi all, Due to bandwidth and storage abuse by Warez and MP3 distributors, we were forced to close a few accounts and remove an estimated 2 GB of files, and place some restrictions on File upload sizes. This means that Members can no longer upload files over 500 KB in size. If you try and upload a larger file, you'll notice that you'll get an 'Unauthorized' message (your browser will ask for your username and password). Due to restrictions on when we can see how large a file you uploaded, you won't get to see this message until *after* the upload is completed (which could take a while at those sizes)! If you feel that your larger file upload is justified and relevant, please contact me (through webmaster(a)zope.org) and I'll get you additional access to make unrestricted uploads. Apologies for the inconvenience! -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

Well, nevermind, in http://www.zope.org/Products/Zope there is this kind of information near each Hotfix that allready give us information to which versions of zope each HotFix applies. And in http://www.zope.org/Products/ there is the "Latest Hotfixes" section that also do the job.

You should be able to use utilities/load_site.py, an uploading utility for zope. It isn't able to use ssl, but that should be easily circumvented by using tools like stunnel http://www.stunnel.org/ It creates an ssl tunnel to your server and runs on linux and windows (and a plenty of other *nixes) - I used just the linux version. You can than create the tunnel from localhost port 2000 via stunnel -c -d 2000 -r yourzopehost:443 and use load_site.py to connect to localhost:2000. I didn't use stunnel in conjunction with load_site/zope, but it should work. You can find related tools at http://www.openssl.org/related/apps.html cheers, oliver

Beware to HotFix Legacy
by J�lio Dinis Silva 27 Aug '01

27 Aug '01

Hi All, I was having some weird permissions problem, really WEIRD!! After trying everything, really everything, I started to became paranoid and suddenly my mind/clicks went into Control_Panel/Products and my eyes went trough the Product's list stoping on a part of this list where the word "HotFix" appeared several times :-). Since we are long time zope users, and we have a zope production site running long before the first hotfix come out, I asked my self: "Do I really need all this hotfixes installed?". I think it was never said one was forced to uninstall zope hotfixes, i.e, it is safe to leave them installed. Well, I uninstalled the old hotfixes and left only the ones related with my version of zope and voila the weird security problem disappeared. I cant describe the problem I had, because it was really weird but this post is to alert everybody to this possibility, i.e: try to run the latest zope with ALL the hotfixes ever released. Then try to do some programatic stuff like create a simple product with a class and then go and do some methods with manage_changeProducts, manage_addProduct, dtml-with "propertysheets.info", etc, and see if your programming security paradigm is breaked with weird security restrictions you never saw before. Maybe some zope guru :-) could say something about the risk or not of leaving the HotFixes installed. One thing cool would be to on zope.org associate to each release of zope the HotFixes released for it. For instance when we choose a version of zope to download, besides the install information, release information, History information, etc, we could see a list of hotfixes one should apply to that version. Maybe create a class Hotfix on zope.org and then relate it somehow with the /Products/Zope/xxx/ folders. Then when a Hotfix class instance is created the person creating it associate that hotfix with some versions of zope, and when we visit a zope version download page we can see a list of hotfixes released for that version.

Upload a file to the file system
by Gilles Lenfant 27 Aug '01

27 Aug '01

Hi, I'm brain dead for a (perhaps) trivial problem for you. I'm trying to upload a file to the file system (using an external method). I got a : <form action="uploadfs" method="post" enctype="multipart/form-data"> ... <input type="file" name="file"> ... <input type="submit" value=" Upload "></form> But I dunno how to handle this from "uploadfs" external method. Any clue ? Thanks in advance. --Gilles

calling manage_addProduct from ZClass method?
by dedmundson＠bigfoot.com 27 Aug '01

27 Aug '01

I have the following hierarchy: - Products - GPScape (Product) - new_cell (Script) - Cell (ZClass) - split (method, Script) I'm getting an error when my split method tries to execute: line 22: gpscape = container.manage_addProduct(['GPScape']) <<<<<< error line 23: nw = gpscape.new_cell(container,'NW',cn,(cn+cs)/2,(cw+ce)/2,cw) Here, container is an instance of Cell and I'm simply trying to set gpscape as a convenience variable for future use, e.g., the new_cell call in line 23. Any idea why this is an error?

Documentation Bug
by Christian Theune 27 Aug '01

27 Aug '01

The DTML Documentation has a slight difference to the real world in it: The description is as follows: raise tag syntax: <dtml-raise ExceptionName|ExceptionExpression> </dtml-raise> but the "expression" is confusing when you want to use userdefined expressions. In plain python it goes following way: >>> try: ... raise "asdf" ... except "asdf": ... print "test" ... except: ... print "notest" ... test >>> So this, combined with the upper description seems to be as following: <dtml-try> <dtml-raise "'stringExc'"> asdf </dtml-raise> <dtml-except "'stringExc'"> your error code here </dtml-try> But, the stringExc is rosen(?) as a 'real' Exception class, so <dtml-except stringExc> would work - which is not clearly at first sight. In the ZopeBook there is a hint on <dtml-raise type="404"> asdf </dtml-raise> which comes up to be the most clean way. The complete working example, most clean imo is following: <dtml-try> <dtml-raise type="userDefined"> asdf </dtml-raise> <dtml-except userDefined> asdf </dtml-except> Any comments on that? Btw: am i getting only responses if i turn of GPG Signaturing? -- Christian Theune - ct(a)gocept.com gocept gmbh & co.kg - schalaunische strasse 6 - 06366 koethen/anhalt tel.+49 3496 3099112 - fax.+49 3496 3099118 mob. - 0178 48 33 981 reduce(lambda x,y:x+y,[chr(ord(x)^42) for x in 'zS^BED\nX_FOY\x0b'])

virtual hosting and error messages
by ed colmar 27 Aug '01

27 Aug '01

Hey friends! I've got a bunch of hosts running on one of my zope servers. Apache, and SiteAccess made it happen quickly and easily. I have a question regarding a unique error message I've been seeing. When filling out a form, I have a value that is being passed to zope as "cost:int" The form works fine when filled out correctly, but returns an error if this field is left blank. Now, this is the behaviour that I want, but I'm trying to track down where the error page comes from. This is different than "standard_error", and the really peculiar thing about it is that it pulls in the "standard_html" header and footer from the root folder, which happens to be a completely different host. Needless to say it is very confusing to have an error pop up on a forign looking page. Anyone know where this file is? or how I can trick aquisition into letting me use the standard_header and footer from the site that generated the error? thanks so much! -ed-
