Re: Caching prob with AHCM and headers

Accelerated HTTP Caching Manager doesn't work out-of-the-box as this thread reported, but the thread had no conclusion: http://mail.zope.org/pipermail/zope/2003-April/134800.html http://mail.zope.org/pipermail/zope/2003-April/135059.html http://mail.zope.org/pipermail/zope/2003-April/135101.html I'm running into the same problem now, also with Apache as the caching reverse proxy, so I was wondering if there was any progress? Here are some of my thoughts; It seems reasonable that without a Last-Modified or Etag header in the response, that a client (and surrogate/ http accelerator) will not have any validators (e.g., If-Modified-Since or If-Match corresponding to last modified and etag headers, respectively) in the request headers. It's probably right that dynamic code doesn't return a Last-Modified header; instead, the RFC includes an Etag header, which is hash of the content, which is much easier to use for dynamic code. The Etag header returned by Zope, however, looks very suspicous; it is empty. This could perhaps be fooling the caching machinery? Perhaps the Etag header should just always be a hash of the content? (Another system worth looking at: http://www.jpcache.com/) Bye, -- Bjorn

Zope 2.7.0-b2 startup error on windows
by Michael Long 10 Sep '03

10 Sep '03

I have recently installed Zope 2.7.0-b2 on windows XP and am getting the same error message as 2.7.0-b1 when starting zope. Is this truly an error message or just informational? 2003-09-05T11:37:23 BLATHER(-100) ZODB Commiting subtransaction of size 5382 Traceback (most recent call last): File "C:\Program Files\Zope-2.7.0-b2\lib\python\Zope\App\startup.py", line 52, in startup m=imp.find_module('custom_zodb',[getConfiguration().instancehome]) ImportError: No module named custom_zodb Traceback (most recent call last): File "C:\Program Files\Zope-2.7.0-b2\lib\python\Zope\App\startup.py", line 52, in startup m=imp.find_module('custom_zodb',[getConfiguration().instancehome]) ImportError: No module named custom_zodb ------ 2003-09-05T11:37:23 INFO(0) Zope Ready to handle requests Thanks, Mike

Strange bug(?) accessing File objects
by Bjorn Stabell 10 Sep '03

10 Sep '03

Hi, Has anyone encountered this problem: When accessing File objects that are not accessible to Anonymous (HTTP and WebDAV View permissions not given), the Basic HTTP Auth window pops up repeatedly even after the user has logged in using the cookie crumbler method, and the user has permissions to view the file. Clicking cancel actually lets the user view the file, but that's not an acceptable solution, of course. I see this behavior with Zope 2.5.1 & 2.6.1 (haven't tried 2.7b2 yet), and I seem to recall earlier versions as well. Bye, -- Bjorn

I am trying to use LocalFS to access a directory in my linux server (zope running on same suse linux server) i am able to see the directory listing, but when i try to access any file i get the following error message ------------------------------------------------ The object at ../../5741.RPT has an empty or missing docstring. Objects must have a docstring to be published. ------------------------------------------------ i get the same error when attempting to access any file i also have a zope server runnin on a couple of other windows computers and it seems to work just fine. the LocalFS is of course treated like a local folder. i would appreciate any help on this issue __________________________________ Do you Yahoo!?

Where is Zope 2.6 Final?
by Andrew Sydelko 09 Sep '03

09 Sep '03

It's been a while since the last beta, and I haven't seen many (if any) changes checked into the 2.6 tree in a while. What's the holdup? With all the problems that exist with 2.6.1 (with packing, especially) I would have thought 2.6.2 would have been out months ago. --andy.

OrderSupport and ExternalEditor
by Christian Tismer 09 Sep '03

09 Sep '03

Hi Zopistas, I had sume trouble to get the extra sorting controls to work for the Ordered Folders. The Ordered Folders just appear(ed) the same as regular folders. After quite some code browsing, I found out: (and there is a not on DZug as well) The problem is, that I'm using ExternalEditor, and this product does a "monkey patch" on the ObjectManager: It replaces the manage_main dtml with its own version, which has no support for ordered folders, yet. The reason why this patch happens is just to ad that little edit pen next to each row in the view. Quick solution, until the author updates his product: copy OFS/dtml/main.dtml to Products/ExternalEditor/manage_main edit that file and add this after line 170: <dtml-comment> This is the only different line: </dtml-comment> <dtml-var expr="externalEditLink_(this())"> Here the same with more context, added lines marked by "*" <dtml-except> </dtml-try> * <dtml-comment> This is the only different line: </dtml-comment> * <dtml-var expr="externalEditLink_(this())"> </div> </td> <dtml-with sequence-key> Remark: I don't know a general good way how products should cope with such problems. It would be nicer if they didn't carry a copy of maybe outdated code, but if they could obtain a copy during installation time (would require some setup script), and identify the place where to insert their ads. But this looks hard if the patched code doesn't provide something like a tag that tells where the place to patch is. ciao - chris -- Christian Tismer :^) <mailto:tismer@tismer.com> Mission Impossible 5oftware : Have a break!

Add Plone Site - AttributeError
by Robert Van Overmeiren 09 Sep '03

09 Sep '03

Hello, I've added Plone 1.0.5 to my Zope 2.5.1 setup running on Suse Linux. When I try to add a Plone site, I get a Zope Error: Error Type: AttributeError Error Value: get I also installed Zope 2.6.1 with CMF and Plone on a Windoz 98 box and I get the same error when adding a Plone Site. I have Zope running on port 8081. Does that have any effect? I've seen numerous postings and bug reports on this type of issue, but no solutions. Is there a solution? Thx, Bob V

RFC: Pythonic Zope Instance Manager
by Luis Lavena 09 Sep '03

09 Sep '03

Hello everyone, I'll like to Request For Comments on something I was thinking for the past weeks: a pythonic replacement of mkzopeinstance script found on zope 2.7, and extend it later to a full GUI client (Win32 for a start). the URL is : http://www.mmediasys.com/zope/rfc.html Please excuse the bad grammar, I'n not a native english speaker/writer, and I'm very tired at this time (didn't sleep well for the past days). There some detractors of the idea (most of them linux evangelist), but the idea is grater than just "use the plain command line boy"... Maybe provide a backend for ISP/ASP companies that provide Zope for their customers, so the setup process of instances or zeo clients could be taked by a script using ZIntanceManager instead of bash ones. I'm looking forward the idea is good looking/attractive to some zope users/developers. When sending comments put on subject "RFC: ZInstanceManager" to avoid my spam filter deletion.

[Fwd: Re: [Zope-dev] ape performance]
by Christian Theune 08 Sep '03

Use the object cache, which will keep stuff in memory, so only the first page view will be slow, the rest should be "as-if-filestorage" speed. That's my experience with it. You can set it by giving the parameter "cache_size" on the database factory with the "setDatabaseParams" method.
