unbuffered html from external method
by Andy McKay 13 Nov '00

13 Nov '00

Is it possible to print unbuffered html output to the user from an external method. It looks to me like I can't, output occurs upon the return and I cant see a way of getting around that. (I have a very long running and expensive external method, I'd like to print out status to the user) TIA. -- Andy McKay, Developer. ActiveState.

Thanks. PortalMember is a ZClass in the PortalMembership product with bases: ZObject, _ZClass_for_DataSkin, _ZClass_for_LoginUser It has what appears to be a standard ZClass property sheet SystemProperties with a string property "password" (it also has other ZClass property sheets CommonProperties, RestrictedProperties, and UserProfile). PortalMembership is a .zexp file created by installing the Membership product.

Aquisition: who know how it does?

Assume the following: ----------------------------------------- Folder1 index_html doc_include_html Folder2 img1 doc_include_html ----------------------------------------- 'doc_include_html' in 'Folder1' has the following code ----------------------------------------- <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p>doc include Folder 1</p> <dtml-var standard_html_footer> ----------------------------------------- 'doc_include_html' in 'Folder2' has the following code ----------------------------------------- <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p>doc include Folder 2</p> <dtml-var standard_html_footer> ----------------------------------------- index_html has the following code: ----------------------------------------- <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p> This is the <dtml-var id> Document. Image: <img src=img1> size: <dtml-var "img1.getSize()"><br> Text: <dtml-var doc_include_html> </p> <dtml-var standard_html_footer> ----------------------------------------- when you call the URL http://localhost:8080/Folder1/Folder2 you see: This is the index_html Document. Image: ..... img2.... size: 11111 Text: doc include Folder 1 Why the acquisition get (correctly) Folder1/Folder2/img2 and the get (???) Folder1/doc_include_html instead of Folder1/Folder2/doc_include_html ? If you remove doc_include_html from Folder1 so that may assume: ----------------------------------------- Folder1 index_html Folder2 img1 doc_include_html ----------------------------------------- you see: This is the index_html Document. Image: ..... img2.... size: 11111 Text: doc include Folder 2 Thanks in advance, G.C. _________________________________________________________ Prometeo srl - The Software Experience Coi Giovanni Voice : +39 (041)5701366 Via Giudecca 15 Fax : +39 (041)5701005 30035 MIRANO (VE) - ITALY e-mail: coi(a)prometeo.it http://www.prometeo.it

Membership and latest LoginManager
by dan＠sol.control.com 13 Nov '00

13 Nov '00

I've been trying to get Membership 0.7.6 working with LoginManager-0-8-8b1 (and it's associated ZPatterns) under Zope 2.2.2 on RedHat 6.2. After probing around it seems that there is a problem storing member passwords. The following trace from print statements inserted in PersistentUserSource illustrates the problem: ================================================================== using crypt encodePassword( testing , scheme=' CRYPT ', salt= U3 ) ==> {CRYPT}U35nKDwqMBaD2addUser setting password for aral to "{CRYPT}U35nKDwqMBaD2" password = "{CRYPT}R0nzSkU8huehY" setting again with direct assignment password = "{CRYPT}U35nKDwqMBaD2" authenticateUser(self, aral , testing ) comparePassword( testing , {CRYPT}U35nKDwqMBaD2 ) using crypt encodePassword( testing , scheme=' CRYPT ', salt= U3 ) ==> {CRYPT}U35nKDwqMBaD2 comparePassword ==> {CRYPT}U35nKDwqMBaD2 == {CRYPT}U35nKDwqMBaD2 passwords matched ================================================================== Source bits with print statements follows at the end of this article. The problem seems to be that: ...manage_changeProperties(password = new_value) doesn't change the password correctly, but ...password = new_value works. Does anyone know what's really going on here? Modified from PersistentUserSource.py:PersistentUserSource: def authenticateUser(self,user,password,request): name = user.getUserName() ok=0 print 'authenticateUser(self,',name,',',password,')' if self.cacheGetAuth(name, password): return 1 if hasattr(self, 'userAuthenticate'): old_au = setuid(self.REQUEST, _LoggingInUser) try: ok = self.userAuthenticate( self, request, user=user, password=password) if ok: print 'self authenticated' finally: setuid(self.REQUEST, old_au) else: # Why does the following always return '{CRYPT}R0nzSkU8huehY' ??? encpw = user.propertysheets.SystemProperties.password print 'comparePassword(',password,',',encpw,')' ok = self.comparePassword(password, encpw) if ok: print 'passwords matched' if ok: self.cacheSetAuth(name, password) return ok def addUser(self, userid, password, roles, domains): user = self.newItem(userid) user.propertysheets.RestrictedProperties.manage_changeProperties(roles = roles) user.propertysheets.SystemProperties.manage_changeProperties(domains = domains) epass=self.encodePassword(password) # This always sets the password to '{CRYPT}R0nzSkU8huehY' !!! print 'addUser setting password for %s to "%s"' % (userid, epass) user.propertysheets.SystemProperties.manage_changeProperties(password = epass) print ' password = "%s"' % user.propertysheets.SystemProperties.password # This works - what is broken with the manage_changeProperties call? print 'setting again with direct assignment' user.propertysheets.SystemProperties.password = epass print ' password = "%s"' % user.propertysheets.SystemProperties.password return user Modified from LoginManager/UserSources.py:BasicUserSource def encodePassword(self, text, scheme='CRYPT', salt=None): """Encode a password""" if scheme == 'CRYPT' and crypt is not None: print ' using crypt' if salt is None: salt = whrandom.randint(0, 2**12-1) salt = saltdict[salt >> 6] + saltdict[salt & 0x3f] pw = '{CRYPT}' + crypt.crypt(text, salt) elif scheme == 'SHA': pw = '{SHA}' + binascii.b2a_base64(sha.sha(text).digest())[:-1] elif scheme == 'SSHA': if salt is None: # XXX random salt selection could be much better... salt = hex(whrandom.randint(0, sys.maxint-1))[2:] salt = sha.sha(salt).digest() ssha = sha.sha(text + salt).digest()+salt pw = '{SSHA}' + binascii.b2a_base64(ssha)[:-1] else: pw = text print "encodePassword(",text,", scheme='",scheme,"', salt=",salt,") ==> ",pw return pw def comparePassword(self, text, pw): """Check if password matches""" salt = self.extractSalt(pw) if pw[0] == '{': scheme = split(pw[1:], '}', 1)[0] else: scheme = '' text = self.encodePassword(text, scheme, salt) print 'comparePassword ==>',text,'==',pw return (text == pw)

ZPatterns: Remapping object from on to another specialist
by Roch'e Compaan 13 Nov '00

13 Nov '00

Another fuzzy freaky area for me: How will one implement the remapping of an object from on to another specialist? Say I have Requesters (Customer's with service requests) specialist that I want to map to Customers Should I still set up a rack and set it's storage to the Customer ZClass and add a skinscript method to copy attributes from the Customer specialist? or Should I simply write a method for Requester, getRequester, which asks the Customers specialist for a Customer. Another question: If I pass an attribute that is not registered with any attributeproviders in a manage_changeProperties call to the object's propertysheet, will that attribute automatically be added on top of the object? Should one explicitly call manage_addProperty? Roché

FIX for the infamous "__call__" bug - testers needed!
by Brian Lloyd 13 Nov '00

13 Nov '00

Hi all - One of the things I _really_ _really_ wanted to fix for the upcoming 2.2.3 release is the infamous "__call__" bug. I have a fix that works according to my limited testing - what I really need is for a few volunteers familiar with the problem to take a few minutes to verify the fix and let me know if the problem goes away for them as well. Attached is an updated version of cDocumentTemplate.c. You can drop this into the lib/python/DocumentTemplate directory of your installation and rebuild it - after restarting the Zope site, the __call__ problem should be gone. I'd really like to hear from some folks on this so I can get the 2.2.3 release wrapped up - thanks!
