You are right: DTML is only rarely used nowadays and its support
deteriorates.
I do not know of a product or patch to improve on this
(also I modified our local Zope to at least report which
DTMLObject caused a problem).
You can improve it by adding __traceback_info__
or __traceback_supplement__ definitions at strategic places
in the DMTL implementation.
If anyone has done this, can I have a copy of your patch - I'm debugging
on an old DTML product, and it is impossible to debug without line
numbers of exceptions.
Otherwise I might have to downgrade zope to 2.5 - thanks for that tip
from Jaroslav Lukesh - I had no idea that it used to be better.
Thanks,
Robert (Jamie) Munro

Very useful. I've based my system on the first link because I didn't need to use POSTs, I just add ?foo=bar to the end of the URL and get it as normal. I added the ability to load a list of urls and element ids one after the other, then only activate the submit button at the bottom of the page when the whole form was loaded. This means the top of the page loads quickly, and the rest loads section by section before people scroll down to it. I was thinking I would have to do something like this, and your links made it really easy.

Just a loop in tal over a sql result set. Just a loop in tal over a sql result set can be extremely slow, depending on the size of your result set. You may not realize that every time you touch one of those resultset record objects the security machinery gets in the game to ensure the executing user is allowed to see the rendered result. This is true for every single field you're trying to show on the page. I've been having similar speed problems with a page that loops through a lot of SQL records. From what I can tell from the profiler, it is the security machinery that is at fault. Workarounds I have used in this situation (eons ago) involved retrieving the resultset in trusted code (inside a filesystem product or an External Method) and converting it to a sequence of simple types, like a sequence of dictionaries, before handing it back to the page template. Those simple types don't cause security assertions and the rendering is sped up immensely. There seems to be a built in method - .dictionaries() that does exactly this. Unfortunatley, neither it, nor a simple external method I wrote to call my ZSQL methods seemed to help me.

Maybe You should take a look at SQLPASPlugin - http://plone.org/products/sqlpasplugin - there are some SHA encryption possibilities, however they are commented by default. So You would have to modify it's code little bit. That's what I was using before. I had no idea that it supported SHA, or that it was so easy to add MD5. That has solved my problem - Thanks It's a pretty silly implementation, though. The point of hashing passwords with MD5 or SHA1 is that if an attacker can read the password files due to some kind of security leak, he still doesn't have the passwords themselves, so he still can't login. Unfortunately, the way it is implemented in SQLPASPlugin, the fact that he doesn't have the password doesn't matter because if you put the hash itself in the password field, you are allowed into the site. It doesn't matter too much for my application, but it's something that should probably be fixed. Thanks for everyone's advice, though.

You write an authentication plugin which takes the credentials as keys
in a dict (e.g., 'login_name', 'password'), encrypts the password using
the same algorithm as your old system, and then compares them. E.g.,
(untested)::
import md5
PASSWORD_TEST_SQL = (select * from users where login_name = '%s'
and encrypted_pw = '%s')
def authenticateCredentials(self, credentials):
login = credentials['login']
clear = credentials['password']
encrypted = md5.new(clear).hexdigest() # or whatever
matched = self._execSQL(PASSWORD_TEST_SQL % (login, encrypted))
if matched:
return matched[0]['userid'], login
return {}
I've edited GMailAuthPlugin, renamed it MD5AuthPlugin, added that code
and removed the google specific code. It doesn't give any errors, but it

LOG(MD5AuthPlugin, INFO, Login attempt: login: %s, clear: %s,
encrypted: %s % (login,clear,encrypted))
Any ideas?

[Zope] Generic SQL insert
Whenever I'm using SQL databases in zope, I always seem to have to make
a ZSQL instance for inserting into every table in my database, and they
are all nearly the same - they just have a list of all the fields in the
database in the parameters, then they say:
insert into [table] ([list of fields]) values ([list of dtml-sqlvars])
I'd much rather have a dictionary of fields and values, and just throw
it at the DB, not having to make those queries for every table. I have
acheived it like so:
mydict = {field1:value1 , field2:value2 ,...}
(fields,values)=zip(*myDict.items())
context.genericInsert(table='table name',fields=fields,values=values)
Where generic insert is the following ZSQL method:
insert into dtml-var table
(dtml-in expr=fieldsdtml-var sequence-itemdtml-if
sequence-enddtml-else,/dtml-if/dtml-in)
values (dtml-in expr=valuesdtml-sqlvar sequence-item
type=stringdtml-if sequence-enddtml-else,/dtml-if/dtml-in);
with parameters:
* table - table name
* fields - list of fieldnames
* values - list of values in the same order
What do other people think of this? Is it a really bad idea?

Re: [Zope] TAL page whitespace removal
Dieter Maurer wrote: Robert (Jamie) Munro wrote at 2006-4-10 13:14 +0100: For example, I downloaded the www.plone.org home page and it was 47704 bytes. I removed all whitespace from the beginning and end of lines, and then removed blank lines, and it was down to 35087 bytes - that's a more than 25% saving, and the output renders exactly the same in web browsers. A much more efficient way is to activate gzip compression for your pages. It not only handles white space efficiently (and correct for e.g. pages with pre tags or similar CSS directives) it also compresses other text. You not only gain 25 % but about 70 % (in the size of requests). gzip will add enormous processing overhead to the server. Striping spaces will add negligible overhead, likely less overhead than it saves. You will not save RAM on the server side (of course), but hopefully (and very likely) the scripts are not the major user of RAM on your site. I have written TAL that produces very large dumps of XML data in the past, even whole sites. It's a really nice way to dump data from a database (SQL or Zope DB), but Zope has to build the whole output in RAM before sending any of it, so it can cause the site to crash. I would hope in this kind of case that the TAL is the major user of RAM on the site, so any saving would be really good, but it all cases (except pre tags, which I would never use) it seems like a possibly significant gain.

[Zope] TAL page whitespace removal
Due to the structure of TAL, the output of TAL pages often includes a lot of whitespace that are added to make the source readable, but once processed the lines they are on can disappear completely. It would be nice if the TAL parser had an option that could remove all whitespace at the beginning and end of lines, and remove all blank lines. For example, I downloaded the www.plone.org home page and it was 47704 bytes. I removed all whitespace from the beginning and end of lines, and then removed blank lines, and it was down to 35087 bytes - that's a more than 25% saving, and the output renders exactly the same in web browsers. This saving will improve load times for the end user, both by being less to download and less for their browser to hold in memory. For the server, the improvements are huge. Obviously less bandwidth is required, but also less space will be needed in the various caches meaning the caches will expire less, and/or be equally functional will less RAM or disc space. The ability to switch off this feature and leave whitespace in for debugging may be useful, but not very, because you can always use an XML indenting tool to get readable output from TAL.

Re: [Zope] Saving a Rendered DTML Document

I also tried using a Zope File object as well as a DTML document that is part of a Local File System. Using a Zope File object does not work since the ouput of a rendered DTML document is text and providing the PHP script a Zope File filled with plain text does not work. The same goes for a DTML document that is part of a Local File System, once the document is rendered it is plain text. Normally in PHP if you replace the file path with a URL starting http:// (or ftp:// etc.) it will fetch the file from the web instead of the file system, no problem.
