Hi, There is a bug in dtml-tree, the bug should be in file: Zope-2.5.0b2-src/lib/python/TreeDisplay.py we need to know BASEPATH1 around line 626 which is: ------------------------------ if exp: ptreeData['tree-item-expanded']=1 output('<A NAME="%s" HREF="%s?%stree-c=%s#%s">' '<IMG SRC="%s/p_/mi" ALT="-" BORDER=0></A>' % (id, root_url, param, s, id, script)) else: output('<A NAME="%s" HREF="%s?%stree-e=%s#%s">' '<IMG SRC="%s/p_/pl" ALT="+" BORDER=0></A>' % (id, root_url, param, s, id, script)) output('</TD>\n') ------------------------------ sorry I don't know how to fix this, thank for your great work for zope.

Re: [Zope-dev] RAMCacheManager and gzip

There is zlib support in Python, and it is used in Medusa already. ZServer does not call it, but the compression stuff is there. There is one good reason not to use zlib though, Micro$oft Internet Distorter does not support content-encoding: gzip and for content-encoding: compress it expects data to be compressed using the Unix compress tool... (I think someone reported this already... oh well) This one needs more work. Netscape 4.7 (Latest version of communicator) does not support HTTP1.1 at all, so it can not do content-encoding at all. (This was a complete supprise to me - Netscape list this as their current version of communicator!) I have to download the latest Mozilla and Netscape 6.2 and see if they work properly. I suspect this is a non-starter as the support is not reliably present in the clients. I don't see any reason to continue this as a project - even if Mozilla and Netscape 6.x support content encoding properly, and even if the smaller browsers (Noteably Opera I guess) support it, so many people use MSID that this would be a major problem - All pages would fail to display as MSID reports that it does HTTP1.1 !!! I do have another server-side caching project that I am about to start looking at though, so we might still see some speed improvements.

IOError [Errno 5]

07 Dec '01

Yo dudes, our zope server shows the following behaviour. 1) runs fine for (a few hours - a few days) 2) then starts spawning the following errors: Error Type: IOError Error Value: [Errno 5] Input/output error Does anybody know what may be causing this? the tracebacks don't make sense at all but is fails somewhere in the ZODB/Connection setstate method. Tia, Sloot.

Do you know the story? Now that I've finished the Cisco Academy, I move on to my Oracle training. I plan on using Zope with Oracle, but I'm looking at the fact that oracle has a J2EE Web application server. Why am I using Zope with Oracle again? My impression has been that the elite private "school" zopers have created some fancy terms and algorithms, and have forgotton to be practical. Yeah, it's cool what I *think* Zope can do, and what it's gonna do in the future. Some say Zope needs 10x growth for next year, but I envision 80x growth. I see Zope hanging from the rearview mirror of some VW, or some kid using it, because it also comes with a cool clicker for his bicycle. I think the most beautiful thing next to my wife and kids has got to be Zope 2.5b1. I do enjoy those that sweat the details, but just the sight of Zope with Page templates and session tracking, with example folders that work on win98.... Please, I'm in heaven. I see Zope at 100x, because it should be a standard anyway. I know why I'm using it, and I happen to like the school of Zope fish. Now, go read <underline>Swimmy</underline> if you haven't. It's *Required* reading in the school I'm from. Peace, -James <nofill>

New Security Rules ... are very frustrating
by Stephan Richter 07 Dec '01

07 Dec '01

Hello everyone, I have a major issue with the new security. Let's say I have class X (a nice Zopish object) and an object Y. class X: Y = Y Now, I am still able to access Y in an instance of X, like: x = X() x.Y but I am not able to access method do_z() anymore. x.Y.do_z() BTW, Y is not a nice Zope object but an instance from anywhere. And setting __allow_access_to_unprotected_subobjects__ does not help much either and it should not be the final solution anyway. Can anyone help? Regards, Stephan -- Stephan Richter CBU - Physics and Chemistry Student Web2k - Web Design/Development & Technical Project Management

Uh, this is brand clarification... Sometimes people (well, people who don't pay enough attention) don't get that company X is associated with product Y. Look what happend to Borland when they changed their name to Inprise but kept the old product names. For those folks who don't pay attention to every detail of goings on in the Zope community, or are not subscribed to lists, or are new to Zope, I imagine that a name discrepancy could be confusing... I hope you aren't saying that basic, well thought-out, marketing strategies are somehow predatory behavior? Let's not even try to compare this to "hijacking" in the style of a certain Redmond-based company.
