MailHost and 2.6.0
by Tony McDonald 28 Oct '02

28 Oct '02

Hi all, The excellent way of sending email via python outlined at http://www.zopelabs.com/cookbook/991178206 (reproduced here for completeness) try: mailhost=getattr(context, context.superValues('Mail Host')[0].id) except: raise AttributeError, "cant find a Mail Host object" mMsg = 'a testful email message \n that contains a few line breaks. \n ~runyaga' mTo = 'runyaga(a)abc.com' mFrom = 'runyaga(a)xyz.com' mSubj = 'mail subject' mailhost.send(mMsg, mTo, mFrom, mSubj) Doesn't work on 2.6.0. You get the following traceback;  Looking at line 125 of MailHost.py you get this... self._send(mfrom, mto, messageText) Whereas on the 2.5.1 version you get this (after much header manipulations), self._send( headers, messageText ) The interface to 'send' hasn't changed though, def send(self, messageText, mto=None, mfrom=None, subject=None, encode=None): We are (were) using this a lot, sending a large quantity of email using Maildrop Host and some python scripts. Now, these scripts don't work. Can anyone shed some light on this? Many thanks Tone. Ps Lest people think I'm all over 2.6.0 - I really like the 'error_log' feature at the top level. It's very handy for debugging stuff remotely (ie when someone calls up and says 'I have a Zope Error', you can get straight to the traceback without needing to train them in HTML, 'View Source' and the like... -- Dr Tony McDonald, Assistant Director, FMCC, http://www.fmcc.org.uk/ The Medical School, Newcastle University Tel: +44 191 243 6140 A Zope list for UK HE/FE http://www.fmcc.org.uk/mailman/listinfo/zope

Authentication with cookies instead of browser.
by Thomas Engel 28 Oct '02

28 Oct '02

Help please! I'm building a comprehensive education resource based on Zope for my school, and I'm trying to learn Zope internals. We are running Apache 2.0.43 with mod-Perl 5.8.0 and Zope 2.5.1, currently on the same machine. Apache serves some content and uses virtual host and proxy for content in Zope with a VirtualHostMonster. Authentication of protected resources works like this: when a request for a protected resource is received, Apache calls a Perl script to check a special cookie from the user's browser. The cookie has the user name and a hash of several values. If the cookie is absent or invalid, the user is directed to a secure campus server which asks for the user name and password, authenticates it against a Kerberos system, places the cookie and redirects the user back to our site. At that point the Perl script finds a valid cookie and allows access. All of this works perfectly! I can get the cookie in the REQUEST object in Zope. I can populate Zope with users. I would like to use Zope's built in role mechanism for permissions. How can I make Zope get the user name from the cookie instead of from the user's browser? I am happy to subclass existing Python code to make this happen. I assume that Zope sends a WWW-Authenticate response header to the user's browser, but I have not yet been able to find the class that does this, and I have not found this question asked before on the lists. Any knowledge or advice is greatly appreciated. Thanks in advance, Tom Engel

RE: [Zope] why run apache in front of zope?
by sean.upton＠uniontrib.com 28 Oct '02

Disclaimer: I've done both Squid and Apache, though I definitely fall into the Squid camp. Regardless, I'll agree that Squid or Apache in front of Zope is the right way to do things. Either can do URL rewriting; either can have access controls; either can do caching; either can do SSL acceleration. Apache's URL rewriting is faster (in-process), while Squid's is much more flexible (external helper, I use pyredir: http://freshmeat.net/projects/pyredir - which is in Python, and has simple enough config file rules that put Apache rewrite rules to shame). Apache has strength in support for transfer encodings (mod_gzip); Squid does not. The problem with transfer encoding is that it doesn't usually play well with cached content. It also really is only a benefit for text, since images are usually well-compressed already. This might be good for an e-commerce site. Squid has faster and more tunable caching. This takes load off the app servers better. Given the performance characteristics of the above two statements, which I believe to be true, I would make the following recommendation: If you are running a site with lots of cacheable content (semi-dynamic, like a news site), use Squid. If you are running an e-commerce site, use Apache, and get the benefits of transfer encoding on your dynamic textual pages that are not likely cacheable.

On servers I administer, we do virtual hosting for many kinds of websites on the same server: filesystem+CGI, filesystem+PHP4, and Zope. Apache provides a convenient and standard way to do virtual hosting. It's easy to front-end Zope sites with mod_proxy, plus I can enable gzip compression on any kind of site with mod_gzip and enable SSL encryption any kind of site with mod_ssl. -dave Marc Lindahl wrote: >I asked the same question and concluded there's no benefit I can see - I >ended up running SQUID in front of Zserver which seems to be just dandy, and >SQUID offers security comparable (afik) to apache, if not better. > >on 10/19/02 9:05 PM, Garry Galinsky at garry(a)galinsky.net scrivened: > > >>This may be an obvious question to many, but not to me... why do so many >>people run Zope behind an Apache server?

why run apache in front of zope?

This may be an obvious question to many, but not to me... why do so many people run Zope behind an Apache server? What are the benefits of an Apache server, or otherwise, what are the limitations of the Zope web server? I currently run Zope alone and am evaluating the benefits of use Apache. Thanks.

frustrated by inability to introspect...
by Skip Montanaro 28 Oct '02

I have the following little snippet of pt code: <form action="edit_list"> <select name="listname"> <option tal:repeat="item container/enumerate_lists" tal:content="item">list</option> </select> <input type="submit" value="Edit"> </form> container/enumerate_lists is a ZSQL method that performs a simple query: select listname from mailinglists All I want to do is display the listnames as form option values. I can't figure out what attributes "item" has. The dir() builtin isn't exposed as far as I can tell. I've been wandering all over the Zope Book for about 20 minutes and have so far been unable to find the attributes associated with the "item" object. Where should I be looking? Is there a rough Zope equivalent to >>> dir("abc") ['__add__', '__class__', '__contains__', '__delattr__', '__doc__', '__eq__', '__ge__', '__getattribute__', '__getitem__', '__getslice__', '__gt__', '__hash__', '__init__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__repr__', '__rmul__', '__setattr__', '__str__', 'capitalize', 'center', 'count', 'decode', 'encode', 'endswith', 'expandtabs', 'find', 'index', 'isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'replace', 'rfind', 'rindex', 'rjust', 'rstrip', 'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill'] or >>> print "".capitalize.__doc__ S.capitalize() -> string Return a copy of the string S with only its first character capitalized. ?

RE: [Zope] Re: [Zope-CMF] Using XRon to backup my portal
by sean.upton＠uniontrib.com 28 Oct '02

In theory, if you are not dependent upon use of ZODB versions, consideration of DirectoryStorage may be warranted: it has a 'snapshot' mode that defers new transactions to a temporary holding directory while the main directories containing objects are frozen, allowing you to use standard Unix backup tools like tar/cpio+find for incremental backup and/or replication. It should be noted that DirectoryStorage also includes a backup.py script that uses the storage to get a list of changed files that will work as a replacement for using the 'find' command. Once the full and/or incremental backup is complete, the storage can leave snapshot mode and all transactions in the holding directory are flushed into the main directory (asynchronously, I think). http://dirstorage.sf.net Cheers, Sean -----Original Message----- From: Jens Vagelpohl [mailto:jens@zope.com] Sent: Sunday, October 27, 2002 7:54 AM To: Ausum Studio Cc: zope(a)zope.org Subject: Re: [Zope] Re: [Zope-CMF] Using XRon to backup my portal i have never seen it that the original file is "frozen" during that copy operation. i have successfully copied Data.fs files up to 5 GB (on linux) without any indication that the website had any trouble. if you can verify that the original turns "read-only" during the copy then that could be a windoze-only thing. jens On Sunday, Oct 27, 2002, at 01:05 US/Eastern, Ausum Studio wrote: > Just a quick question about it: > > What happens to the ongoing transactions?
