Re: [Zope] Re: zope fork in external method - mysql connection dropped
You might also try running zope under runzope instead of under
zopectl. IIRC zopectl itself sets signal handlers and performs a
fork before starting zope, so the inherited environment may not be
what you think it is.

grandparent's publish function (ZPublisher.Publish, line 104). The
good news is that the grandchild continues to do it's work, but the
bad news is that the user receives an error page instead of the
redirect to the "wait_page".
My guess is that this has something to do with the various forked
processes sharing the MySQL connection, and in particular, I'm
guessing the child process that exit(0)'s is closing the
connection, which is then unavailable when the grandparent tries to
use it.
Here's the interesting part: if I put a sleep(1) line in between
the waitpid() line and the return line, I get no error. It would
appear that the 1 second pause provides enough time for a new MySQL
connection to be made after the previous one is killed (less than 1
second is not enough).
This is a very ugly fix, though... I can't guarantee that 1 second
will always be enough... can anyone suggest a cleaner solution?
Perhaps I shouldn't kill the child with sys.exit(0)?

Jonathan-
I'm emailing you because I saw your post a few months back at:
http://mail.zope.org/pipermail/zope/2006-May/166574.html
I've been doing my best to find answers on existing posts, but to
no avail. Perhaps you can send further pointers?
On my system, a user can hit a page that initiates a long
database query. If the user hits the stop button and tries to
refresh, it messes things up (by interrupting the code upon
return of the query), so I came up with a solution that almost
works:
I put all the code into an external method, which forks. The
parent returns a redirect to a "waiting" throbber page that uses
Ajax to poll whether the query is done. The child then goes on
to do the hard work.
This is working as desired, with a single exception: zombie child
processes. Where can I learn more about forking processes in zope
external methods? I've read about the double-fork method, but
that hasn't resolved the problem...
A few ideas for reaping dead child processes:
1) implement a SIGCHLD handler
2) when a spawned child process is finished its 'zope processing'
have it write its process id to a file (be careful when accessing
files, you will need locking to eliminate problems that may be
caused by zope's multiple threads) and then have a clean up
routine which kills all of the processes listed in the file (this
could be an independant clean-up routine which wakes up on a
regular basis, or it could be built into the 'spawning' process
which does the clean up before it spawns a child).
3) as the last thing it does, have the child process issue a kill
-9 system command to kill its own process (I haven't tried this
myself, but it may work and it would be simple to implement)
Good luck!

I'd recommend using the 'subprocess' module for such stuff.

The problem is actually that SQLPASPlugin is schizoid about whether or not to use encrypted passwrods (see the 'updateUserPassword' method for more weirdness).

Re: [Zope] New kubuntu zope/plone installation problem
I just installed zope and plone on a new Kubuntu installation using the Adept package manager. Zope comes up on port 8081 -- which was a bit of a surprise, as I expected it to be on port 9673 as in other Debian distributions -- but I can deal with that. 8080 is standard port for Zope. You may change it in zope.conf file. The problem is I don't know the admin username and password. Is there a way to either find out what they are or to reset them to something known? you may run ./zopectl from your's /bin and execute adduser command in the prompt (be sure that zope is not running) to add new user. Other thing is that I think it is better to install zope from sources. Then you have control on what is installed, where and what is user account. -- Maciej Wisniowski ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

That is strange.
As you can see
"Products.Transience.TransientObjectContainer._do_finalize_work"
the session is not cleared before the "notifyDel".
The real content might be in "item._container" which you can access with
the "TransientObject"s mapping API ("keys", "values", "items", ...)
