Do you mean using the traceback module ? I've just searched about it

try:
# do my stuff
except:
traceback.print_exc(file=sys.stdout)
raise
Is this the best way to show the stack trace ?
That would be one way to do it. If you are using the python logging
module, another way would be to use the logger.exception method, which
automatically adds the exception info, including the traceback, into the
log message.
Ie.
try:
# do your stuff
except:
logging.exception('Oops, an exception occurred')
# or use your_logger_instance.exception
raise
Other than that, I would have thought you should be able to
track down
the source of the 'global name' exception by grepping your
source code
for uses of 'anxnews_urllocal' without a '.' in front of it. Is it
possible that you are doing something like this, for example:
query.select_by(anxnews_urllocal 5)
When you probably mean:
query.select_by(table.c.anxnews_urllocal 5)
Man, you got it !! :)
The only line of my simple code that have a anxnews_urllocal without
a preceding . is here:
if anexo.anxnews_tipof == Anexo.IMAGEM:
cronometro.start()
renamed, size = _gerar_thumbs(local,
SIZE_WEB, SIZE_THUMB)
if renamed:
anexo.anxnews_urllocal =
posixpath.splitext(anxnews_urllocal)[0] + .jpg
This renamed condition is very rare... It only occurs when I'm
dealing with a BMP image...
And my log file confirms that.. I was manipulating a BMP image... :D
So I'm changing splitext(anxnews_urllocal) to
splitext(anexo.anxnews_urllocal)
Hope that helps,
It sure helped...
Thanks !
Roger
Well, it certainly makes a change - normally I'm the one asking the
questions ;-)

Cool... I am using python logging... I'll try your suggestion... :)
Thanks again,

Any hints about what could be causing this exception ? one or both of thread synchronization / module import based issues. id be curious to know if the PropertyLoader exception occurs within the Mapper.compile() method. I do have a mutex on that system to avoid concurrency issues when the mapper first compiles (its one of the only mutexes within all of SA), but you know how grumpy mutexes can be. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups sqlalchemy group.

Some details I forgot to mention: I'm using: * SQLAlchemy 0.3.6 * Postgresql 7.3.4 * Linux RedHat kernel 2.4.20-8 Other important detail: looking at my log files, I noticed that the message: global name 'anxnews_urllocal' is not defined appears several hours after the message: 'PropertyLoader' object has no attribute 'strategy' Thanks Roger On 4/11/07, Roger Demetrescu [EMAIL PROTECTED] wrote: Hi all, I have a daemon with 2 threads to control upload / download of some files (they use SQLAlchemy to find out which files must be worked).
