WebServers with Exotic Features
by Fabio Akita 16 Jun '00

16 Jun '00

Hello again. More problems to be solved :) Now I've been trying some exotic things:) The tests are still going on in a NT machine. Here's what I'd like to do : I have installed Apache for NT (yes, I know it's still beta but I am waiting for a new Linux server that will be here in a few days :) on default port 80. I also configured IIS to be on port 8090 and ZServer to be on it's default port 8080. I'd like to do the following things using the Rewrite module : Point zope.server.com to www.server.com:8080 and point iis.server.com to www.server.com:8090. I tried things like these: RewriteCond %{HTTP_HOST} ^zope\.server\.com RewriteRule ^(.*) http://zope.server.com:8080$1 [R] But if I do this the user will see http://zope.server.com:8080/page.htm written in his's browser instead of http://zope.server.com/page.htm, which I'd prefer. I am trying to ally this to the Proxy Reverse module to accomplish this result (and I wouldn't like to use the pcgi version of Zope, I prefer to try ZServer). The ProxyPass alone do part of the job, when Zope has the Site Access Product, but cannot accomplish all of these goals. The other thing is that I'd like to add the static cache feature of the Rewrite module. Something as the following example: RewriteCond %{REQUEST_FILENAME} !-s RewriteRule ^page\.html$ page.cgi [T=application/x-httpd-cgi,L] I'll use the pcgi version if there's no other way and I still want the URL hidding feature (zope.server.com instead of www.server.com:8080) If all these really work fine maybe the Apache could be a better alternative to Squid, mainly because of it's well known robustness, flexibility and log accuracy. Maybe some of the things I am trying to do will be impossible, but it's exciting trying to do such things :) If someone know some of these features (mainly, I'd like to know more about the static cache feature and Rewrite+ProxyPass modules). And the NT machine is still just for tests, so maybe the Linux version of Apache can give me more flexibility as I am already used to it. Thanks.

Odp: [Zope] Re: [Zope-dev] Zope ...2.1.7 update - patch for EMarket 0.1.03

Hi Steve (Apologize for my poor english and I hope that you will understand something :)). Its happends _only_ for Zope 2.1.7 and 2.2b1 Currently I not have a traceback but was not possible to create instance of EMarket (and other product which creates own MailHost insance too) mesage was (or something like): 'localhost' is not keyword parameter. My patch is _only_ for Zope2.1.7 and for Zope2.2 where API for MailHost was changed. For this versions method MailHost.add() have a form: def add(self, id, title='', smtp_host=None, smtp_port=25, REQUEST=None): but old (for Zope 2.1.6 or ealier) had a form: def add(self, id, title='', smtp_host=None, localhost='localhost', smtp_port=25, timeout=1.0, REQUEST=None): For new MailHost API (which based on Python standard smtplib, and it seems will be 'official' version in the future) parameters localhost and timeout was removed. Besause 2.1.7 was deleted and 2.1.6 stays back as last stable version, my patch not needed now but for Zope 2.2 still will be (I think). I think that portable solutions for EMarket its simply omitting localhost (as in my patch) because its not needed anywhere in your excellent EMarket product. Of course my previous patch is minimal, only for compatibility. I attached more full patch with smtp_port support. Take a look for attachements.

But.. maybe will be a general problem for contributed products wchich uses MailHost (such as EMarket, ETailer, maybe WordlPilot etc) bacause MailHost API (especially MailHost.add) method was changed in 2.2 branch (in current 2.1.7 too), due to use of standard smtplib module. And there is a big and serious problem (I think not only for me:). On my Win box Zope2.2b1 craches (GFP), dont allow add objects (eg. Folder), dont allow enter Control Panel if product incorect installed, etc.. 2.2b1 is very , very unstable for now. Of course I understand the reasons (a lot of very important changes). If I would help to avoid some problems I can test v2.2b2 extensively, especially on Win32 box (Win98, Win2000) and a little (for comparison of behaviour) on RH Linux.

dtml-sqltest to support SOUNDEX?
by Kyler B. Laird 16 Jun '00

16 Jun '00

I think I've determined that there's no clean way to specify a function to be used on a sqltest variable. I'd like to be able to do something like <dtml-sqltest soundex(lname) column="soundex(last_name)" type=nb optional> but it doesn't seem possible. I hope that I am missing something. Yes, I know there are lots of kludges to get around this, but then I lose the clean design of sqltest - especially if I want to use "optional" or "multiple". Any suggestions? Thank you. --kyler

The explantion: SQL methods are much more stupid than DTML methods! If used in the way you do it, SQL methods look only in the REQUEST object and not in the namespace. This means (if called from a WEB request, i.e. REQUEST is defined): <dtml-call new_scheme> is equivalent to <dtml-call "new_scheme(REQUEST)">. Your <dtml-in>, however, has placed the fields into the namespace "_" and not in the REQUEST object. You cannot use <dtml-call "new_scheme(_)"> either, because SQL methods require a "get" method from their first parameter ("_" does not have it). For the moment, you have to use on of these ways: 1. <dtml-call "new_scheme(new_product=new_product, scheme=scheme)"> or 2. <dtml-call "REQUEST.set('new_product',new_product)"> <dtml-call "REQUEST.set('scheme',scheme)"> <dtml-call new_scheme> I prefered 1. in my solution.

Re: Zope 2.1.5/6/7 upgrading issues

Hi guys, First of all, I'd like to apologize for the pain factor here - there has been some CM process changes around here and the 2.1.x branch is suffering as a result :( I have a proposal, however, that I hope will make this much easier. How about if we: o release a "Product" today that, if you install it and restart your Zope (no matter what version), patches the hole at runtime (in memory change only). o retract the 2.1.7 release in favor of getting 2.2 beta 2 out on Monday, which doesn't have the cruft problem of the 2.1.x branch and contains all fixes to date (and which will fix SQLMethod problems and support the SiteAccess release that Evan is making today). I can have the new "hotfix" product ready by 12:00pm EST today. Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Zope Database Connection
by Ivan Raikov 16 Jun '00

16 Jun '00

Hi all, I am trying to figure out a way to use a Zope Database Connection object from within a Python class, which is then going to be subclassed by a ZClass. In my Python class, I want to have an instance of the parent class of all Zope Database Connections, so that I can work with all types of connections (be it Gadfly, Solid, or whatever). However, I am not sure which class this is. I think it is Shared.DC.ZRDB.Connection.Connection. Is that correct? Also, in the creation form of my ZClass, I'd like to have a connection selection dialog, similar to the one in the creation form of ZSQL Method. How do I get a list of connection instances in the current folder? Thanks, Ivan Raikov

Yes - that is one of the nice side-benefits of doing it this way: look in the Control_Panel/Products and you will see the hotfix product in the listing. Click on it and click the "README" tab to view the readme file that describes the hotfix. Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com
