Problems with temporary connections
by Etienne Labuschagne 08 Jul '05

08 Jul '05

I need to make a temporary connection to the ZODB. I have really good reasons relating to performance and not wanting have objects in the current cache getting removed from the cache on why I don't want to make use of the connections in the pool. I can elaborate on this if really nescessary... The supposed way to get a temporary connection would be: conn = Globals.DB.open(temporary=1) which works fine. The problem is that one cannot: conn.close() as this puts the connector back into the pool, where it shouldn't go and if you do it, causes all kinds of nasty lockups, etc. I have read some old posts that advise against using temporary connectors as this can lead to memory leaks (as I can attest to after trying to use them) and that temporary connections seem to be "broken". How can I get a connector, that will not be used by other normal processes, that I can release cleanly when I am finished with it? Or at least ensure that one of the connectors in the pool is reserved for a specific process and that that connector will only be used by that process. Can I do this by giving a "version" to the connector? Any suggestions? Etienne

Without this your connectiion will just hang at the urlopen command, *as there is no timeout*. Also look out for what others have aid in respect to https, no expirience with that myself. There are some applications for Plone to use PayPal (PloneMall / PlonePayPal), you might want to look at these for sample code too. Regards, Sascha

Pluggable Auth Service ... how is it used?
by Richard Jones 07 Jul '05

07 Jul '05

I'd like to get session-based login going, and on the surface PAS appears to support that. First up, is there any documentation? I've set up in my PAS "acl_users" the following objects: 1. "cookies" - a Cookie Auth Helper active for Challenge 2. "session" - a Session Auth Helper active for Extraction, Update Credentials and Reset Credentials 3. "users" - a ZODB User Manager with a single user "test" 4. "roles" - a ZODB Role Manager with the "test" user assigned to "Manager" Then accessing a "Manager" protected method inside the folder brings up the login form from the Cookie Auth Helper, but submitting that form does nothing (it returns the empty form to me). Switching the "cookies" object to handle Extraction, Update Credentials and Reset Credentials makes the login work, but I'd like to use the session. The docs that come with the product talk about Decorators and Property Sheets used to extend the user properties, but I can't even find anything with either of those names in the UI. The interface has "Scriptable Plugin" with a teasingly disabled "Validation" interface -- which I have found to mean user validation. I'd like to enforce valid email address capture ... when I can figure how to actually capture an email address, that is. Richard

paypal IPN. Debug messages missing. Script goes zombie
by Ed Colmar 06 Jul '05

06 Jul '05

Hi all! I've been hacking together a few seperate paypal IPN connections, some code from basion, and some from random web scrapings... Anyway... Things are working for the most part, except that this method for some reason dies when using urllib.urlopen(), and what is really wierd is that I get no error message, it just hangs. I am running an older version of zope, but I have never seen this behaviour before. The debug (-D) flag is set in start. here is the code I am using... As far as I can tell my syntax is proper... ??? def paypal_notify(self,address_street='',address_zip='',first_name='',last_name='',payer_business_name='',payer_email='', payer_id='',payer_status='',residence_country='',quantity='',receiver_email='',receiver_id='',custom='',invoice='', memo='',auth_id='',auth_exp='',auth_amount='',auth_status='', remaining_settle='', mc_gross_x='',mc_handling_x='',mc_shipping_x='', num_cart_items='',parent_txn_id='',payment_date='',payment_status='',payment_type='', pending_reason='',reason_code='',txn_id='',txn_type='',exchange_rate='',mc_currency='',mc_fee='', mc_gross='', mc_handling='',payment_gross='',settle_amount='',settle_currency='', auction_buyer_id='',auction_closing_date='',auction_multi_item='',for_auction='', option_name1='',option_name2='',option_selection1='',option_selection2='',tax='', subscr_date='',subscr_effective='',period1='',period2='',period3='',amount1='', amount2='',amount3='',mc_amount1='',mc_amount2='',mc_amount3='',recurring='', reattempt='',retry_at='', recur_times='',username='',password='',subscr_id='',test_ipn=0,REQUEST=None): """ take a IPN from paypal, and update the database """ print "Initiating paypal IPN" # they want us to send back their same shite (and we've just nicely # deblocked it from the REQUEST...) print "DEBUG = STARTING" requestform = REQUEST.form print requestform['quantity'] # debug test requestform['cmd'] = '_notify-validate' print "DEBUG = INSERTED NEW VALUE" print requestform print "sending request back to paypal" requestparams = urllib.urlencode(requestform) print "DEBUG = Encoded Request" print requestparams data = urllib.urlopen('https://www.sandbox.paypal.com/cgi-bin/webscr', requestform) print "DEBUG = urlretrieved" print data.read() print "DEBUG = DATA READ" ---------------------------------------------- I see all my debug print commands until "encoded Request" and requestparams, so it is getting lost on the urlopen call. Thanks for any help or tips. I'll post the final IPN method when I'm done. Cheers! -ed

Zope won't give up WebDAV Lock
by hpinson＠indepthl.com 06 Jul '05

06 Jul '05

I have a regularly occuring WebDAV problem: A file edited via ExternalEditor gets a WebDAV lock. Upon closing (Textpad in this case) occasionally the lock is not released. The lock is not listed in Control Panel > WebDAV Lock Manager, therefore cannot be released there. Restarting Zope does not release the lock. This is getting to be a terrible problem. Once a lock is in place, the file cannot be changed, renamed, or deleted at all subsequently. Zope is 2.7.6 Final, Fedora Core 3, Python 2.3.3 Here is the only reference that I have been able to find in the log: 2005-07-06T10:22:00 ERROR(200) SiteError http://.../PUT Traceback (most recent call last): File "/var/zope276/lib/python/ZPublisher/Publish.py", line 101, in publish request, bind=1) File "/var/zope276/lib/python/ZPublisher/mapply.py", line 88, in mapply if debug is not None: return debug(object,args,context) File "/var/zope276/lib/python/ZPublisher/Publish.py", line 39, in call_object result=apply(object,args) # Type s<cr> to step into published object.
