ZCatalog: path & summary indices not generated
by Shane Rowatt 03 Oct '01

03 Oct '01

Zope Version: 2.4.1 on linux. When I tried to add a ZCatalog followed by finding objects to index using the default indices provided (path, summary, id, title etc), the 'path' and 'summary' indices are never generated. The 'summary' index is always an empty string and the 'path' index is 'None'. To get around the 'summary' not being indexed for DTMLMethod and DTMLDocument objects I had to add the following method to DTMLMethod.py: def summary(self): "Support for searching - the document's contents are searched." raw = self.read() stripped_raw = re.sub("<.*>", "", raw) n=min(200, len(stripped_raw)) return stripped_raw[:n] which basically strips out anything between '<' and '>' tags which should strip most of the DTML and HTML tags out to give a half decent 200 character summary. Unfortunately I tried the same with the 'path' index by adding the following to DTMLMethod.py def getPath(self): "Get path" return getPath(self) def path(self): "Get path" return join(self.getPhysicalPath(), "/") but the 'path' index only works it is a FieldIndex. When it's a PathIndex I get the value of None for all cataloged items. Surely someone else has come across these problems before using this basic catalog stuff?? Shane Rowatt Astracon Inc.

RE: [Zope-dev] syslog

It is actually always used unless Zope is started read-only. Its not easy to follow *how* this happens - and I am still not sure *why* its done this way. As for the how: ZLogger starts out with a from zLog import *, it then sets up the list of standard logger objects, and defines the log_write function. Later, z2.py transplants the log_write function from ZLogger into zLOG, where it is used by the implementation of zLOG.LOG (the usual logging API) > Have you verified this by trying it? Definitely yes - my syslog filled up with access log information. A question for all syslog users; is it ever useful to send access logs to syslog? (I can't think of good reason, but my syslog zen quotient is still low). Is anyone else even using syslog? Anyway, for anyone else interested, below a patch so that the configuration of access-syslog uses different environment variables to event-syslog.

Problems with Oracle DA and Dates
by Dario Lopez-Kästen 02 Oct '01

02 Oct '01

(I apologise in advance for the crosspost, but I think this is a valid question on both the zope-db and zope-dev lists. If you disagree, flame away, and I'll never do it again. oh, btw: flame in private mail, please) Hello! We have run into a showstopper problem here where it seems (we're not sure yet) that there is a severe problem using dates returned from the Oracle DA adapter. Other possible culprits include LocalFS, Transparent Folder, Formulator and the source release of Zope 2.4.1. The problem is that Zope either dies, core dumps and dies, or slows down to a crawl. We are using the Zope 2.4.1 release, with Transparent folders and LocalFS, latest, and a sligthly modified Formulator. There are about 2-6 people working and developing in it during all hours of the day (24 hours). Unfortunately nothing shows up in any of the logs, so they are of little use; I don't even have a traceback so display. We *think* we found sometign pointing at LocalFS in one of the coredumps, but we are lowly non-unix programmers, and have no idea if this is accurate info or not. It could just be un-collected garabage memory. Is anybody noticing anything similar, or if you have any opinion on what might be going on, please reply; we are in DS mode here (we are having a prototype presentation during two weeks, starting tomorrow) and are feeling a bit desperate.

RFC: two "enterprise zope" proposals
by Chris McDonough 02 Oct '01

02 Oct '01

Hi Folks, If you get a chance, please read and comment on: http://dev.zope.org/Wikis/DevSite/Proposals/ExtendedForensicLogging A proposal to extend Zope's "forensic" logging capabilities [implemented currently by "Big M" logging] to record system state such as CPU usage, swap usage, etc. http://dev.zope.org/Wikis/DevSite/Proposals/ToleratingHangsAndLeaks ... another proposal for extending Zope with a mode where it would restart itself every so often or as it determines its in a pathological state. Thanks! -- Chris McDonough Zope Corporation http://www.zope.org http://www.zope.com "Killing hundreds of birds with thousands of stones"

[ann] developer tools
by kapil thangavelu 02 Oct '01

02 Oct '01

Developer Tools release ExtSearch/ExtIndex - Allows FS search from zope, integrates with swish++, includes a pluggable index and standalone version EventChannel - simple publish/subscribe system for zope with different channels and filters. SQLEngine - loads up sql methods from the fs, and provides a container for them, currently hardcoded to openacs's query xml syntax, but those who llike snakes should have no problem adjusting to other formats. License: GPL documentation on these varies, most integrate with the help system to provide documentation. download: http://www.zope.org/Members/k_vertigo cheers kapil thangavelu

Read only ZEO
by Tim Hoffman 02 Oct '01

02 Oct '01

Hi In some of the overview documents discussing ZEO, there is reference to a ZEO client potentially mounted a ZSS in read only mode. (I want to have some ZEO's in read/write as well) I have been trying to work out how this might be achieved but have pretty much drawn a blank, has anyone done this I have any idea how I might go about doing such a thing. I ideally I would like to control what clients can connect and whether read only or read/wright by IP and/or some token RGds Tim -- Tim Hoffman Zute Pty Ltd mobile: 0411 068888 fax: +61 8 6210 1883 email: timh(a)zute.net

Hi! Has anybody also had that with a Zope 2.4.1 instance (Linux)? It happens not only with Metapublisher (as in the example), but seems to occur quite randomly. It might be a problem with my local install, but even if it is, it should not happen (as I just have some custom Products installed) ...

somehow OT: How do I get a tar file containing the ".dtml" files only?
by Joachim Werner 01 Oct '01

01 Oct '01

Hi! I am working on internationalizing a Zope 2.4.1 instance with ZBabel and providing a set of patches for Zope 2.4.1. My idea was that things would become much easier if I had a tarball that just contains all *.dtml files and the folder structure for them, so I can distribute the tarball as a patch that can be applied to a plain 2.4.1 instance. Do we have any Unix/Linux/GNU experts on the list who know how to write that as a shell command? I am sure that with tar and grep and some pipes or so it is possible, I am just too dumb to find out the right syntax ... Cheers Joachim
