[Zope-dev] determining database manager type from z database connection?
Is there a generic way to determine what 'brand' of database manager a Zope database connection is connected to by interrogating the connection object?

[Zope-dev] CopySupport bug
There is a subtle bug in the CopySupport module that makes it impossible to copy and paste a folder that contains a ZCatalog with CatalogAware objects in indexed in the catalog also in that folder. The reason is as follows, CopySupport calls a hookable method manage_afterClone (which is hooked by CatalogAware). It does so after a copy is made of the object but BEFORE the copy is mounted in the ZODB. manage_afterClone in CatalogAware tries to reindex the object, and in doing so tries to derive its URL for use as the ZCatalog uid by calling absolute_url on the object. This fails of course because the object as yet has no URL because it is not mounted. The error reported is a KeyError on SERVER_URL. To make a long story somewhat shorter, I have a simple patch for this, but there is still one more subtle bit of behavior to take note of: When the ZCatalog is copied, all of its indexed data gets copied. Then the new copies of the objects index themselves. This means that the copied catalog has twice as many objects in it as the original. This bugged me at first, but it makes sense and I don't see any obvious solution that would be consistent.

The -M log perhaps won't show you the actual operation that's causing the hang, but it will show you the entry point into a routine which causes the hang.

If you see a request come into ZServer, and you see the request go into ZPublisher from ZServer, but ZPublisher never returns any data to ZServer, that's an indication that something is wrong. A SQL method hanging would look like this, it's the same thing as any other Zope component hanging. The "big-M" log is your friend, even in this case.

Re: [Zope-dev] another Zope hanging..
Hi, most problems with hanging zope come from external RDBMS-access. You wont see anything useful in the logs because there are some objects published before the *sql-method is hanging. If you have a monitor program for your database, you see many blocks on tables or rows during this times. I expect it with DB-adapters not fully thread aware and - with to high timeout. In fact it seems we need timeoutsockets and asynchronous rdb-access. If one thread is hanging, in the scope of 120 instructions, zope has to wait before the global interpreter lock frees. So if its stuck in the call of a C library (database adaptors are most in C) it cannot continue until the call returns. Regards Tino Wildenhain --On Donnerstag, 3.

Alright... so you're getting an OSError 11, and you're using Zope 2.3.1. errno 11 is "temporarily unavailable" which means about as much as "foobar feeblefar" as far as I'm concerned ;-). Though you've said the -M log isn't helpful here, I think it is.

[Zope-dev] another Zope hanging..
Hi! I also now have some problems with a hanging zope. I got something like this in my stupid logfile: 2001-05-03T13:44:39 ERROR(200) ZServer uncaptured python exception, closing channel (exceptions.OSError:[Errno 11] Die Ressource ist zur Zeit nicht verf?gbar [/opt/Zope-2.3.1-src/ZServer/medusa/asyncore.py|poll|83] [/opt/Zope-2.3.1-src/ZServer/medusa/asyncore.py|handle_read_event|335] [/opt/Zope-2.3.1-src/ZServer/medusa/select_trigger.py|handle_read|77] [/opt/Zope-2.3.1-src/ZServer/medusa/asyncore.py|recv|287] [/opt/Zope-2.3.1-src/ZServer/medusa/asyncore.py|recv|475]) Now my question is simply if I can catch this exception somewhere and get some traceback etc. Actually I am quite confused from the inner workings of medusa so I dunno where to start searching. Can anyone help? (I know about the -M logging but unfortunately this does not help that much..) cheers, Christian -- COM.lounge http://comlounge.net/ communication & design [EMAIL PROTECTED] ___ 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 )

Well the analyzer script only shows the first 20 or so chars of the URL by default unless you pass it the --verbose argument, so this might serve to do some "cleaning". Also, getting rid of the URL altogether is something you can do by using Unix "cut" or on windows putting the results of the analyzer script into Excel and deleting the column with the URL in it. > Hurm, d'ya think it'd be worth it?

This probably isn't meaningful... unless it is. ;-) Conflict errors
are normal... I wish they wouldn't be so "big" and have an UPPERCASE
word in their description.
