quick question: I just updated both my python install (241-242) as well as updating webware from the svn ( I know I should not have done both at the same time) and when i tried to run webware (after running install.py again) I received an error that in application.py at line 125 I could not do float - none. It appears to me that the Profiles.starttime is not being set and so it defaults to none. I added a line setting the starttime to self._startTime which fixed the problem for me but I thought I would pass the info to the group. Has anyone else had this problem?

I would recommend reading the Python documentation on pickling here: http://www.python.org/doc/current/lib/pickle-inst.html But briefly, database connections are definitely not going to be picklable by themselves. Class instances are picklable, by default pickling all of the attributes of the class. But you can add special __getstate__ and __setstate__ methods to a class to control exactly what part of the instance's state is pickled and unpickled. So you could wrap your database connection in a class, and have only the connection _information_ be pickled, not the connection itself; and reconstruct the connection from that information on unpickling. I hope that leads you in the right direction... I'm not really sure what happens if the session can't be pickled to disk, but it certainly causes big problems if you try to restart your app server so you really ought to avoid it. - Geoff --- This SF.net email is sponsored by OSDN's Audience Survey.

Most classes are pickleable, but only if they don't have anything
transient -- like an open file object, a socket, or in this case a
database connection.
One way to handle this would be to put the connection parameters in the
session, and create the connection in your servlet's awake() method (or
probably your SitePage's awake). If you use DBPool, it will reuse old
connections based on those parameters, or make a new connection if
necessary. So when you restart the server, the connection will be
recreated.
If you are doing long transactions then you need to be more sure that
you get the exact connection back. Then you might put a connection ID
(that you make yourself) into the session, and keep the actual
connections in a module global. Like:
_connections = {}
_count = 0
_connLock = threading.Lock()
def saveConnection(conn):
_connLock.acquire()
connID = _count
_count += 1
_connLock.release()
# Make sure it's extra unique:
connID = '%s_%s' % (time.time, connID)
_connections[connID] = connection
return connID
def getConnection(connID):
try:
return _connections[connID]
except KeyError:
raise KeyError, Your connection has expired, been closed, or
has been lost in a server restart
# and maybe redirect or something intelligent based on this

Title: Message
I
first noticed this problem using IE-on-Windows. I also see the problem in
several other client situations (these are all on Linux):
1.
Using a Python script with urllib.py
2.
Using wget
3.
Using Netscape on Linux
Number
3 gives the most status information: The error page displays, right down
to the uid/gid/etc. information, and the status bar states "12K read (stalled)"
and the "wait cursor" (the little wristwatch) displays until I press Stop, at
which point the status bar states "Document done." At the end of the page,
then, is a horizontal rule, followed by "Transfer interrupted!" in
bold.
Now
that I see what Netscape on Linux shows, there may be a clue. Is there
supposed to be more error information AFTER the list of uid/gid/pid, etc.
The last think I see is 'getuid 500' (500 is the nobody user on my
box). If there's more information being collected, perhaps that's where
the hang is.
Cheers!

[Webware-discuss] WebKit Error traceback pages don't close their
connection?
When I get an error traceback page (it
happens a lot, I make a lot of mistakes), it seems like the HTTP
connection doesn't get closed. The symptoms I see are that the
traceback page loads, down to the end (I think), where the IDs print,
but the IE "globe" keeps spinning until I press the Stop button on the
browser.
When I request the /Examples/Error servlet
via urllib in a Python script, it hangs at the point of retrieving the
page. If I press Ctrl-C, there's nothing in the output file.
Any words of advice about what's going on and
how I could fix it? I'm trying to write a cheesy automatic test
for a servlet page that will simply look for the presence of the
traceback. What I'm doing as a workaround is assuming that no page
will take more than 30 seconds to load (browser and servlet on the same
network), and handling an alarm if the timeout is exceeded.
I appreciate any advice or pointers to
information you can provide.
Thanks. By the way, the fancy traceback
is a great boon for us--much easier than finding and tailing a
logfile.

I posted this to another mailing list and thought it might be of interest at webware discuss. Seems to be a nice example of using Webware at least. Randy I have reworked my web site, http://zunzun.com, and would like anyone interested to review it for me. Several major and minor changes: 1. All code is memory-resident and run by a daemon, currently running with 5 threads, from http://webware.sf.net. Normally each time a CGI script is invoked a lot happens on the server side, such as loading a perl or python interpreter, libraries, scripts, etc. and initializing same. This does not happen in my case and the site response is lightning fast for dishing up dynamic content that is generated on the fly. Webware even caches database connections so these are reused rather than re-created. 2. Every web page on the site is dynamically generated thanks to #1 above. Only the home page is static as I cannot redirect my site host to use a cgi script for the home page. This is a *huge* reduction in site maintenence for me! 3. I dropped frames in favor of Cascading Style Sheets (CSS). Frame communication was becoming a lot of programming overhead and using DIVs in CSS is very easy besides looking nice. All DIVs are hidden and only show upon menu select, which works extremely well. The site now has no frames. 4. I added user entry for initial coefficient values. 5. I ensured the Levenberg-Marquardt solver cannot infinite loop on errors. 6. I added more 2D and 3D equations and equation categories. The next change I am now working on is to add an automatic equation finder. This would fit your data set to all functions and show the user a list to choose from, based on fit statistics and the model visualization plots. ___ Webware-discuss mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/webware-discuss
