Correct? No, but I'm really not familiar enough with the ZODB machinery and zope internals to tell do much more than wild guesses. The problem seems to be that the ZODB and things like Zcatalog know about subtransactions (you can disable them with the latter one), but some (the most) zope db-adapters don't. Now zope seems to use subtransactions internally and to expect the DAs to provide them also (commit_sub), but for now it seems to not completly clear when and why - see the thread "subtransactions". For file-uploads the threshold may be <~ 120kb, that is which bites people with loginmanager/postgres. The workaround from I cited should at least solve the zope-error, but I have no idea if it can hurt. The best thing would be to properly implement the missing methods in the DAs, I guess, unfortunately this is above my head for now.

You mean you want to use AUTHENTICATED_USER like a cookie, i.e. loggin in and every password authenticates? Using basic auth it might be a nice way to get cookie functionality without using cookies. You could write a custum method which triggers authentication and rewrite the method of GUF to always return 1. If someone wants to "log in", he could click on a link to this method. Maybe Logout!! You are now logged out! could be a starting point. If it is contained in standard_html_header it would force everyone to choose a user name, and in conjuction with the GUF-hack mentioned above he would always be logged in - well unless he decides to call himself "Anonymous User" (luck that this isn't coward ;).

First, I meant double quotes (") not single one's ('),
in case that wasn't clear.
I know that for mysql, postgres, oracle there are column names
which will surely break dtml-sqltest as it is implemented now.
Either lowercase letters (oracle, as you also noted) or uppercase
(the other two). I guess sql-keywords and special characters as
column names - ok, not a very clever idea - will break sqltest
on all of them. At least I didn't find a way to get it to
work without patching zope.
Searching the web I find various hints that many odbc,jdbc adapters
and sql-db frontends use quoted names per default (psql).
Unfortunately I don't want to pay to the ANSI-commitee for reading
into the sql-standard, but I'm pretty sure every newer database
supports that.
> Even if it does, the proposed change will probably break

Right, how about adding a argument like, let's say "sql_quote"? ;)
Unfortunatly, I fear I'm have not enough knowledge in zope's
internals to offer a clean patch.

I would like to see quoting as a standard, but you have a point.
Maybe sql_quote is the way to go.

Either because the browser ignores the redirect after an 401 Unauthorized, or because of the nature of dtml-raise which maybe prevents zope from interpreting following code. Maybe someone can shed some light on that. Perhaps you could try this: Logout!! You are now logged out!

Re: [Zope] apache/mod_rewrite and user-logging (semi-OT) - workaround
Whoa,
seems like my problem was not very interesting...
Anyway, I found a solution and hereby make it public.
To get apache to log usernames, one has to invoke
the apache's authentification machinery. I found
out that one can plug perl-modules into apache for
doing auth and that there's even a module which
does exactly what one needs here, Apache::AuthAny,
which always succeeds.
package Apache::AuthAny;
# file: Apache/AuthAny.pm
use strict;
use Apache::Constants qw(:common);
sub handler {
my $r = shift;
my($res, $sent_pw) = $r->get_basic_auth_pw;
return $res if $res != OK;
my $user = $r->connection->user;
unless($user and $sent_pw) {
$r->note_basic_auth_failure;
$r->log_reason("Both a username and password must be provided", $r->filename);
return AUTH_REQUIRED;
}
return OK;
}
1;
__END__
The corresponding entry in http.conf is
PerlAuthenHandler Apache::AuthAny
AuthType Basic
AuthName "Auth_Realm"
require valid-user
One just has to make sure that the realm is the same as
in zope and everything goes fine.
So on to the next, has anybody an idea what would be a good/easy way
to link zope authentication to apache's?
It might be interesting to use mod_python i.e. for extending
zope's authentication to files/directories served by apache
(one could have done the same as above with mod_python, it's just
that I didn't want to install that for a five-liner).
cheers,
oliver

[Zope] apache/mod_rewrite and user-logging (semi-OT)
This is not directly a zope-question, but maybe someone has figured out how to solve this. I'm using apache with mod_rewrite to redirect requests for a certain directory from apache to zope (with option [p]). Now for the first time I can't get apache to do want I want it to, that is logging the usernames into apaches logfile. Apache does this only when enabling apache's mod_auth via AuthType Basic AuthName "Ihr Login..." AuthUserFile "/httproot/web/bogus_userfile.txt" require valid-user or similar, but the silly thing then also wants his own authentication. I am not able to get it to extract the username without really requiring apache authentication. Does anybody know how I could accomplish that? Any dirty tricks to get apache to *think* it authentifies, but letting through every username/password combination, so that zope can do it's job? And no, putting any of this combinations in bogus_userfile.txt is not an option ;->. Another possibility (which gets me more on-topic) is to do that in medusas http_server (which logs a '-' hardcoded), but the only way I could imagine (and code myself) would be to do the base64-decoding there and that seems not quite elegant, even more because apache's log-files hold the client-ip in this situation and therefore are more informative anyway. cheers, oliver ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Well, not 2.2.4 but 2.2.3, and I had some bugs when trying it on a copy of a production server. I couldn't get the "old" installation to work in a different directory, although I thought I changed every path in start etc.. I also deleted all pyc files and reran wo_pcgi.py. One symtom was that loginmanager didn't acquire users from a level above. Later on it wouldn't want to to the sql-query, nothing showed up in I postgres' debugging output. Btw. can anybody tell me if and how it's possible to relocate an installed Zope? Back to your question, loginmanager now works fine for me now, and it did so flawlessly on a fresh installed zope. Did you eventually try to use the loginmanager-with-SQL-howto in the toplevel folder? IIRC, this will lock you out permanently. Did you reuse a user name (just a guess that this might cause problems)? Try to find out whether and which sql-queries are issued by LoginManager, I guess other dbs than postgres will also allow to find that out.

Maybe the newest built of html-kit (from 29. Nov).
The changes file suggests that ftp-support is now very
good. (save/load/update ... everything you can do with a
local file seems now to work with remote-files too).
Look at http://www.chami.com/html-kit/news/
A very interesting feature for zope seems to be the following:
" Ability to map local folders to remote servers, for the purpose
of previewing files with server-side scripting through the server
("Edit | Preferences... | Preview | Edit Preview Rules...").
The user interface for this option has not been finalized."
HTML-Kit is free and very customizable, I really like it.
The developer is very responsive and there's a load of plugins
available - chances are that any modifications to make it
play better with zope can be incorporated.
And it's free (as in beer).

[Zope] ZopeFind expression
I fear this is anywhere in some howtos, but I couldn't find it. How can I get properties of a DTML-Documents parentfolder as expression in ZopeFind? At least I couldn't get the "Find" in Zope's webinterface to show all DTML-Documents whose parent-folder has a certain property.

Thanks for your reply. I use ZPoPyDA (0.6.4 says the readme). I think I will not apply that patch (thanks nonetheless), because I have no requirements for indexing big amounts of text.

Well, I just got there by chance after several hours of digging around. I first thought perhaps some DTML-Document was "bad-behaving". (not that I had an idea how it might do that.)

[Zope] ZCatalog and LoginManager - be aware.
Hi, I just wanted to mention a IMO bad pitfall when using ZCatalog, for the sake of sparing others some time. I'm running Zope 2.2.2 with LoginManager with SQL in a subfolder and was getting the following error when trying to find dtml-documents into ZCatalog: Error Type: AttributeError Error Value: commit_sub Traceback (innermost last): File /home/local-extranet/web/zope3/Zope-2.2.2-src/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /home/local-extranet/web/zope3/Zope-2.2.2-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/local-extranet/web/zope3/Zope-2.2.2-src/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /home/local-extranet/web/zope3/Zope-2.2.2-src/lib/python/ZPublisher/Publish.py, line 175, in publish File /home/local-extranet/web/zope3/Zope-2.2.2-src/lib/python/Zope/__init__.py, line 235, in commit File /home/local-extranet/web/zope3/Zope-2.2.2-src/lib/python/ZODB/Transaction.py, line 261, in commit AttributeError: (see above) All other object-types (incuding dtml-methods) seem to work. I have put no restrictions on which files I want found, but restricting something to reduce the number of found objects helps. I fiddled around somewhat and discovered that disabling subtransactions in ZCatalog does help (required for using ZSQL Methods and ZCatalog in the same transaction). Now I use SQL-based LoginManager, but why on earth did it only fail on DTML-Documents? Is it because I have much more of them so only then ZCatalog's subtransactions come into play?

What about putting in your standart_html_footer. In light of the current search&replace thread, remember to put admin.website.com in a variable ;->.

Don't know about Netscape, but it becomes more and more difficult to get IE _not_ to try to be "smart" about any file you download. In this case I think there's some kind of transparent mechanism which kicks in and tries to transparently decompress files of type application/x-tar. Guess it's a helper for compressed vrml .wrl.gz (or similar) files. In this case renaming to .tgz works, but I think I saw the same mess the other way around when IE didn't remove the .gz suffix but nonetheless transparently decompressed the file. These things are extremely annoying when dealing with relativly unexperienced clients who, say, just want to _download_ an .avi file with a left-klick. MS has implemented a lot of magic there, AFAIK IE even tries to guess the filetype by its content in some cases and then ignores each and every http-header which might suggest otherwise.

Jørn, I ain't no apache geek, but I took a look at two nice how-tos on zope.org.

Combine that with virtual-host directive of apache and you are as flexibel as one can get. Naturally /local need not to be the only folder which isn't proxied to zope. The only problem is that apache doesn't care for zope's authentication machinery, I would love to have a module for apache which could enable that (nice dream...).

First, sorry for my (nearly) full-quote, but I think it makes this discussion more readable. To your question, from my testing (I did this with column names only, but I suspect the same behavior for table-names), postgres is case sensitive, but - as I wrote - in another sense. If you don't quote the column-names, they are converted to or interpreted as lowercased names. _But_ if the real name of the table/column is _uppercase_, it will not be matched by this lowercased name - in this sense postgres is case-sensitive. Postgres needs quoted names in sql-queries to respect capitalization (sp?) - and I couldn't get to generate them. This was a major problem for me, because I had to work with a bunch of tables which were exported from foxpro and dbase, and their names were uppercased in the process. cheers, oliver ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Hmm, I'm not very clear about differences between handling of (table, column) names in sql-databases, but postgres IS case sensitive (in some sense). Few days ago I wrote to messages to this list describing my problems with postgres and capitals in column-names. The handling of these will render useless, because it doesn't quote the name of the vars. I that case postgres will not respect capital letter (will turn them lowercase) but also won't find the column which name is written uppercase. I think it would be usefull to collect the behaviour of different databases and try to find a solution which will work with all of them.

[Zope] dtml-sqltest and capital column names
Hi,
I'm using zope 2.2.2 with postgres 7.0.2 and ZPopyDA 0.6.4.
I encountered a problem with dtml-sqltest and capitals in column names.
Well, I simply couldn't get it to work because postgres requires
column-names with "special characters" like capitals to be enclosed
with quotation marks, ie. "COLUMNNAME" instead of COLUMNNAME -
IIRC '_' also won't work.
The problem is that dtml-sqltest only renders
select * from table where COLUMNNAME='5'
which will be interpreted by postgres like
select * from table where columnname='5'
Unfortunatly throws the
obvious error and everything else I tried didn't work too.
In the end I patched lib/python/Shared/DC/ZRDB/sqltest.py
to do what I want.
165,166c165,166
< if has_key('column'): self.column=args['column']
< else: self.column=self.__name__
---
> if has_key('column'): self.column='"'+args['column']+'"'

Any comment whether this would also apply/be necessary for other dbs?
And if not, would there a better place (anywhere in ZPopyDA)
to change/add some code?
Or did I just miss something obvious and there's a sane way
to make dtml-sqltest work with postgres and capitals.
cheers,
oliver

Hi, I guess Client.py or one of the libs it uses is somewhat broken. I get the exact same error when trying to use utilities/load_site.py from 2.2.0 (and Oleg Broytmann already sent a mail with the same problem to this list). load_site from 2.1.6 works fine though, perhaps that means you can use Client.py from 2.1.6. cheers, oliver ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
