To your image in properites add a string property called Last-Modified with value Wed, 15 Mar 2002 19:02:17 GMT And your broken image problem will disappear. This is not zope specific, I think it's apache since I've had the problem with PHP4 using a fusebox architecture. -Kevin Smith >Since this afternoon, I am fighting with ZServer. >Currently, it seems Zserver is winning .... >I do not understand, what I see... >At work: Zope 2.1.6, Sparc Solaris 2.7, Linux Netscape >4.51 > Sometimes, images are not shown by Netscape (broken >image). > No "simple" reload is able to change this, however >a "forced" reload > lets Netscape show the image correctly. > From then on, the image is always shown correctly: >by "simple" reload, "forced" reload or directly (served from cache). > The strange thing, inside "Image.index_html" the failing > "simple" reload and the succeeding "forced" reload >look > completely identical. >At home: Zope 2.1.6, Intel Linux 2, Linux Netscape 4.5 > All images are always shown correctly. > However, there is no log entry in "var/Z2.log" for > about 50 % of the requests that are answered by > a 304 response.

File size errors for manage_addFile
by Satheesh Babu 21 Aug '00

21 Aug '00

Hi all, I've a form using which files need to be uploaded to Zope's database. The processing method has Proxy of Manager. However, if the uploaded file is more than 150KB, manage_addFile which is called from inside my processing method gives an error which says Zope error: in commit_sub If I upload using normal Zope interface, there is no problem with any size file. There is no problem with my form+processor for files less than this size either. I've the same error for manage_addImage too, but the file size limit there is 50KB. Platform: WinNT4.0, SP6 Zope 2.1.6 Any help is greatly appreciated. Many thanks in advance vsb vsbabu(a)csoft.net http://www.mamlegault.com/~vsbabu/

Builing DynPersist.c - LoginManager / ZPatterns ..
by Jørgen Skogstad 21 Aug '00

21 Aug '00

Kindest .. I've been trying to implement LoginManager with ZPatters today, but have failed so far. Can anyone give me some input with this. Would really like to have some pointers in the correct direction. DynPersist.c It is the file above it fails on .. and I think I saw a message that this is a "common" problem others have experienced. Is this correct? And does anyone have the shared lib for RH v6.2?? .. would really apriciate it if someone would contribute 5 mins of their time! Have a real nice day.. and thanks in advance. ;) -- Med vennlig hilsen, Jørgen Skogstad

RE: [Zope] SQL trees...

Confirmed. Downgrading to 2.1.4 fixed it. How annoying... Thanks a lot!

Which Zope version do you use ? When I read your message I have a deja-vu: I encountered the same output when I use SQL based trees under Zope 2.1.6, it is a bug somewhere in the SQL method handling that appeared in 2.1.6 and is fixed in 2.2.0. Solution: switch back to 2.1.4 or forward to 2.2.0 or patch the existing 2.1.6 Philipp Auersperg (zwork)

Security (proxy role??)
by Sven Hohage 21 Aug '00

21 Aug '00

Hi, I've got two questions. 1.Is Zope 2.2.0 masking the length of the passwords? 2. the more important-> I'm using a method to change properties by form. The user i.e. Tim has the role manager in the highest user_folder and acquisition is kept but Zope tells me that the user is not authorized. Why??? Thanks!

Zope is very slow!
by Christiano Anderson 21 Aug '00

21 Aug '00

Hi, This is my first message to the list... I'm currently running Zope 2.1.6 + Apache 1.3.12 (with proxycache). The system is a Solaris 5.6 on a E450 with 2GB Ram and 2 X 450mhz... The Zope is running with Apache, using the ProxyCache and SiteAccess to convert all requests from port 8080 to 80. My problem is: The system is *too slowly*! Does anyone know how to optimize the Zope to run quicker? Is there anything wrong with this configuration?? Thanks a lot, Christiano Anderson

RE[2]: [Zope] Product inheritance question (similar question)

>> from PA import A, ..... <whatever you need> I am only using dtml and not writing directly python code ! So I do not believe this is possible. >> Almost unbelievable. But true. But I will have again to do some test. (I do not have the time right now, and I did most of my test with the previous version of Zope) What I will have to do: - create a Package (Zope product). - create a class in this package, and a method (my_method) - create another package. - create a class in this package that inherits the class of the other package. - check that the method my_method is visible from within the second package.

Security Problems upgrading to Zope 2.2.0
by Stefan Bambach 21 Aug '00

21 Aug '00

Hello zope-users, I upgraded my Zope application from version 2.1.3 to 2.2.0 . Now I have problems with the new security system. e.g. 'test.py' in Extensions directory: class test: def __init__(self): pass def sayhello(self): return "hello" def initialize(self): return test() Now I created an external method that is named 'test', it's function name is 'initialize' and the module's name is 'test'. The code <dtml-with "test()"> <dtml-var "sayhello()"> </dtml-with> produces an 'Unauthorized: sayhello' after I canceled the requester. Of course this is only a test function, because my real functions didn't work, too. All checkboxes of the external method 'test' are checked. So all users should have the rights to access this method. Right ? What's wrong with this code ? bye. Stefan Bambach

RE: [Zope] Strange behaviour on authorization
by Jarkko Veijalainen 21 Aug '00

21 Aug '00

now, i have defined same owner to every document in that folder, but it did'nt help me. I cranked litle bit my pages and discovered little more where is the problem. Problem isn't POSTING data, it's the return value that Zope doesn't want to publish. <clip> <font face="Verdana, Arial" color="#ffffff"> <dtml-let resDTML="Imap('Authentication',REQUEST,1)"> <h2>User <dtml-var "resDTML.cn"> <dtml-var title_or_id></h2> </font> <FORM ACTION="email_headers" METHOD="POST" > </TD><TD><font color="#000000" face="Verdana, Arial, Helvetica" size="1"><dtml-var "resDTML.account">  </TD> </clip> Problem tag is <dtml-var "resDTML.cn"> that that causes following traceback, when i remove this tag. Traceback bugs me about Unauthorized: account, which is 2nd value from external methods returned object resDTML. So problem is publishing contest of resDTML called in <DTML-LET>-tags. This don't make any sense if i have to validate every return value from external method, it's just unacceptable. In external method, i have simple class and instance of that class is return value of method. I repeat this again, ALL THIS THINGS DID work with Zope 2.1.6. How can i fix this?

A *major* change between 2.1.x and 2.2.x is in the security dept. 2.2.x runs all methods using the security level of the _owner_ of the method, regardless of whether this is a lower or higher level than the currently authenticated user. My guess is that your method has no owner (which is what pre-2.2.x objects default to when run under 2.2.x). This means it is running as anonymous which does not have rights to do what you want. Specify an owner for the method that has sufficient rights to do what you want and try it again.
