Hmm, recall that PathIndex error I reported a few days ago? That was also an unindex error, also exercised by migrating to 2.6.0. I wonder why the process of *migrating* should cause dups in the index...?

OrderedFolder has NoBabelTag.py and exUserFolder has dummyZBabelTag.py to do the same thing. OrderedFolder does that in clean way. exUserFolder - not (at least on FreeBSD).

Ok. What general solution should be? One of the possible ways would be to reserve big stack enough for all cases but only small portion of it (generally used by apps) turn into phisical memory.

Re: [Zope-dev] Zope crash & restart
Hi, it look like it works! I have to give site some time to run to be sure. Where I can vote for a bug or to give comments? On SF.tracker issue? to make it go into release. As far as I understand the patch is quick-hack to make it work and do not solve the issue completely, just increase the stack size... There should be better solution, isn't it? Will it go into Python-2.1.4? m. -- Myroslav Opyr zope.net.ua * Ukrainian Zope Hosting e-mail: [EMAIL PROTECTED] cell: +380 50.3174578 On Wed, 15 May 2002, Behrens Matt - Grand Rapids wrote: > Myroslav Opyr wrote: > > > As far as I remember the issue was solved in Python 2.1.3, wasn't it?

[Zope-dev] Zope crash & restart
Hi, There is installation: Zope Version (Zope 2.5.1 (source release, python 2.1, linux2), python 2.1.3, freebsd4) Python Version 2.1.3 (#1, May 5 2002, 06:29:09) [GCC 2.95.3 20010315 (release) [FreeBSD]] System Platform freebsd4 ZODB contains an instance of modified CMFSite (translated in Ukrainian, CMFSiteUA). System works perfectly well even on Zope 2.5.0 on Win32 platform but crashes on FreeBSD. Site was Exported (from Win32) and Imported (to FreeBSD). Local Filesystem View folders were deleted and recreated manually. As soon as somebody tries to touch that CMFSiteUA Zope crashes and restarts. Workaround found is: to enter management interface somwhere deeper, for example /Examples/manage or /Control_Panel/manage. Then Zope loads parts of the system into RAM and appears possibility to run the site. Sooner or later, when there is sufficient time-frame to unload all objects out of the RAM cache (no user activity), system turns back into unusable state and again there is need to bring it up with /Control_Panel/manage... Any hints? BTW, there is absolutely no output in debug mode. Just usual INFO(0) messages on startup. Crash and again usual messages. Watchdow process remains into memory but new child performing requests processinf are respawned. And again INFO(0) messages are flushed into stdout... Any help would be appreciated.

Thus I wanted to point out that PHP is not really what you can compare to Zope. PHP is comparable to Python. They are just languages. PHP community has excellent PHPnuke and PostNuke products which has unprecedented success. The is alsow Midgard, PHP CMS. Zope is Application Sever disposing a number of services to applications written with it. We should find competitor in PHP world to compare to. I do not know one. Speaking of Application Servers I can name ACS (TCL/Java) and Enhydra (Java). They are competitors of Zope, not PHP.

Let's find out what we have and what we want. First of all we have strict hierarchy in ZODB where each object appears only once in the tree. Thus to access to an object it is only one way from root down to an object through containers. All security in Zope is based on that pattern. I am omitting Acquisition machinery to simplify (and I do not see it clearly in the context here). The idea is to allow user to specify several points of presence (pop) for an object. Does this break security? Probably yes, but in what case? If an object from higly secure envionment appeared somewhere in Anonymous zone, what then? Yes, Anonymous is able to alter object. But there was reason for that! Is Anonymous able to get out of the shared object to secure environment? No in no simple way. Sure if an object was DTML and Anonymous placed trojan horse in the script and someone from secure environment executed the code then we run in a problem. But we can warn user! And we have a lot of "Restricted..." techniques, maybe one can be applied here? >Comparing it to Unix hard links is fine, but Unix doesn't >use Acquisition to handle security, so the comparison is >not apples-to-apples :) We need to spell out the exact semantics >(*especially* wrt security, but also in terms of its effect on >ZODB identity semantics, effects on undo, etc.) > Ok. I am not too well in English but I'll try to do my best. If it is not hard for you give several words of explanation of "ZODB identity semantics" and "effects on undo", not everything is clear for me. >Security in particular is very concerned with *containment* >path (rather than just acquisition path) in order to prevent >"stealing" access through acquisition wrappers.

AFAIK there was and are a lot of concernes refarding soft- and hardlinks in /tmp folder, with sticky bit, etc... But they are usually solved with different means. Yes, Zope and ZODB is much more complex. But why we have to limit ourselves because something is difficult. Why not mark the feature as experimental (red button, a lot of warnings, for instance) and make it available to SuperManager only ;) I'd be glad to get feedback, thanks, Myroslav -- Myroslav Opyr zope.net.ua <http://zope.net.ua/> ° Ukrainian Zope Hosting e-mail: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> cell: +380 50.3174578 ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
