Why the new DTML syntax uses a hyphen rather than a colon
by Jim Fulton 09 Aug '99

09 Aug '99

I'd like to clarify a point that keeps coming up in the DTML syntax discussion, namely, the use of a hyphen, rather than a colon, as the prefix delimiter for DTML tags in the new DTML syntax. The existing DTML syntaxes are *not* XML compliant. DTML code is not XML well-formed in a whole host of ways. We absolutely intend, probably in the near future, to provide an XML variant of DTML. I think that there will always be XML and non-XML variants of DTML. When coming up with the new DTML syntax, I chose not to use a colon because I thought, and still think, that using a colon would imply XML compatability that simply wasn't there. Further, in the future, I want it to be easy to distinguish between XML and non-XML versions of DTML code. So, in summary, the new DTML syntax doesn't use a colon because it isn't XML. The future XML-variant *will* make use of XML namespaces and will use colons (e.g. <dtml:in>....). Jim Note that an advantage of the XML DTML syntax will be that people will be able to use whatever nick-name they want for DTML tags. People will be able to use '<dtml:in>', '<z:in>', '<jim:in>', '<zope-is-the-coolest-thing-since-sliced-bread:in>' or whatever. <jim:wink> -- Jim Fulton mailto:jim@digicool.com Python Powered!

PHP v. Zope
by TR Henigson 09 Aug '99

09 Aug '99

Are there any comparisons between the performance of PHP and Zope on Apache where PHP is running as an Apache module? As I understand, Zope can only run as a CGI process. Ted Henigson

This is because _v_ objects are stored in the cache with other objects. When the deactivator code comes around to delete some of the objects and toss them in the persistent storage, _v_ objects are simply thrown away. So you are correct, _v_ objects are not guarenteed to live as long as the Zope process or between HTTP requests. > > 'name' values are *sometimes* retained from one get to the next > within a _bobo_traverse__(), and again, I can't identify when or > why.

looking for ideas on access control...
by Anthony Baxter 09 Aug '99

09 Aug '99

For an application I'm building, I'm looking at trying to figure out a simple and robust method of doing access control - there's a bunch of different users who each have access to certain objects (stored in Oracle), and they should get different access based on which object ids they are trying to access. What I want to be able to do is have something I can call in standard_html_header which does something like * get AUTHENTICATED_USER. * get REQUEST['object_id']. * lookup in SQL the rights that this user has over the object with object id object_id. * set the roles of the user for this transaction, to either 'anonymous/none', 'readonly', 'readwrite', or some other variation, and let the permissions on the appropriate DTML and SQL methods control what they can do. What's the mechanism for editing the roles of a transaction? Is it even doable? Could I simply use a UserDb, add 'object_id' to the list of arguments for sqlListUser, and make the SQL magic supply the roles? Will this get called for each transaction? thanks, Anthony -- Anthony Baxter <anthony(a)interlink.com.au> It's never too late to have a happy childhood.

ZSybaseDA: multiple sql-statements
by Frank Buhr 09 Aug '99

09 Aug '99

Hi, the new ZSybaseDA 1.0.1 seems to be very restrictive regarding multiple statements in one ZSQLMethod. Even simple cases as this one (inspired by the "auto commit hint" at the end of the README) don't work: ZSQLMethod: commit transaction  SELECT * FROM bar An error is signaled if there are multiple statements (queries) and at least one has a "select" in it: Zope-2.0.0b3-linux2-x86/lib/python/Products/ZSybaseDA/db.py: if len(queries) > 1: result=[] for qs in queries: if select_m(qs) >= 0: raise 'Query Error', ( 'select in multiple sql-statement query' ) I'am using temporary tables for some of my queries. With 1.0.1 it is impossible to do this: COMMIT TRANSACTION  SELECT * INTO #foo from something   other SELECTs with empty result set...   Only the result of this query should be displayed  SELECT * FROM #foo  DROP TABLE #foo The solution would be to take the result of exactly one select query if there are more than one. If all other selects have an empty result set, nothing is lost -- Even more: my queries start working again! To be concrete -- I would suggest to change the query() method in Products/ZSybaseDA/db.py like this: def query(self,query_string, max_rows=9999999, select_m=regex.compile('[\0- ]*select[\0- ]+', regex.casefold).match, try_again=1 ): global failures, calls calls=calls+1 db=self.db try: c=self.cursor self._register() queries=filter(None, map(strip,split(query_string, '\0'))) if not queries: raise 'Query Error', 'empty query' if len(queries) > 1: result=[] lastQueryWithSelect=None for qs in queries: if select_m(qs) >= 0: lastQueryWithSelect=qs if lastQueryWithSelect is None: # non-select queries only: execute them all for qs in queries: r=db.execute(qs) result.append([qs, str(`r`), calls]) desc=nonselect_desc else: # use cursor on last select, but execute the other queries for qs in queries: if qs is lastQueryWithSelect: r=c.execute(qs) result=c.fetchmany(max_rows) desc=c.description[0] c.close() else: r=db.execute(qs) if r and r[0]: raise 'Query Error', ( # explain... 'multiple selects with non-empty results in multiple sql-statement query' ) else: # one query only query_string=queries[0] if select_m(query_string) >= 0: r=c.execute(query_string) result=c.fetchmany(max_rows) desc=c.description[0] c.close() else: r=db.execute(query_string) result=[[query_string, str(`r`), calls]] desc=nonselect_desc failures=0 #c.close() except self.Database_Error, v: [no change below] -- Frank Buhr

Z Search not working?
by David Kankiewicz 08 Aug '99

08 Aug '99

Working with the current CVS checkout... Can someone test out creating a Z Search... I'm getting a nonexistent ZQueryIds error message when trying to create one with the management interface.. If someone else with the current CVS can reproduce it than its bug that needs to be looked into/ added to the Collector?. Please let me know if it does the same thing for you. David Kankiewicz P.S. Just got done catching up/checking through the Mailing list for this bug and reading the discussions on the latest topics, I think its awesome product and can't wait to see what ZEO is and how Zope builds on the current projects/developments...
