How does releasing under the GPL make the world a better place? Hopefully Zope will soon be considered a universally available system library and this will not matter any more ;) For Zope it's not sure, but for Python, as well as for all what people usually call open source languages, the license of choice should be the GPL, or at least the LGPL, in order for the language in question to not become bastardized by some powerful entity. I see GPL as a good license for GCC and other _compiled_ languages, but for an interpreted language GPL or even LGPL could well be viewed as forcing _anything_ written in it to be forced under *GPL. Even more ridiculous would be the situation where pure python modules can be proprietary but modules written in C must be *GPL (think picle vs cPicle) The problem with plain GPL, as mentionned in my previous message, is that this would make a lot of people run away. However the LGPL seems to be a very good choice, because this wouldn't allow the core (of Python or Zope) to be bastardized with proprietary versions, while still allowing proprietary products/extensions to be created. AFAIK the ability to be bastardized is one of main strengths of python. It would be extremely hard to bastardise the main python (as it requires you to brainwash Guido), but having proprietary (or open-source) versions that behave in some ways differently, like ZODB-python that has transactional persistency seems to be a feature and not a bug of Python license. And yes, a thounsand times yes, I use the GPL for ideological reasons, because I really believe this will make the world a better place.

So, if the mails going to lots of people, the page takes ages to return. Perhaps it would be better to solve this by configuring your sendmail (or other SMTP MTA) to be non-blocking, i.e. store-and-forward. Also you could send just one message to all the recipients instead of sending individual messages. This is the problem I had where our mail server was taking lots of time to send messages (it was doing lots of stuff to make sure the address was valid) so submitting posts on Squishdot.org was taking ages too. What, IMHO, is really needed is a mailhost/sendmail tag type thing that gets a message and a list of addresses to send it to. If it could do that in a seperate thread/process/whatever so that whatever calls it doesn't block, that'd be great. Of course, it'd need to have a 'hook back' method provided so any errors that occured could be dealt with. I wonder how mailman does this stuff and if the code could be borrowed for Zope?

Aha, well, the GPL-vs-BSD-vs-MPL-vs...! :))) As PostgreSQL mailing list member you (like me) saw these debates many times. I don't think we need to continue the flame here :) True. The problem is that in some perverted fashion it seems to me that if I use a GPL library with something the whole thing should go GPL, i.e. my use of ZPoPyDA could make me obliged to distribute Zope under GPL, which I of course can't do and thus i start feeling scizophrenic ;) There are people who loke BSD-style licensing, and there are GPL devotee. In this far-from-ideal world it is hard to say what is more free. I, personnaly, love GPL and publish whatever I can under GPL. I personally don't have anything against (L)GPL either, its just my gut feeling that having _multiple_ potentially clashing licenses inside what should be ideally one package is confusing as the interactions of licenses can't be understood by noone ;) -- Hannu ___ 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 )
Re: [Zope] Interbase / Cacheing - A thought
Ian Sparks wrote: Had a thought that I wanted to share. Interbase has a feature known as "event alerts". In a trigger you can post "events" which are just fixed data strings e.g. "DataAdded" or "Insert_tblUsers". PostgreSQL has them too. It's not (afaik) supported by DB-API, but could be used in a DA that talks to some lower level API. A client database connection can register to listen to these events. I don't know if any Zopeish Interbase access method supports this (ODBC doesn't to my knowledge) but it would be incredibly useful for synching cached database objects. Zope could hold a representation of the table data in cached objects for quick access. Each object could have one or more "event" methods which related to a database event. When the database adaptor received an event message from Interbase it could inform all objects with a matching event method (these methods would refresh their cached data with current values from the database). In this way database and Zope cache could be synced *without* having to poll the database at an interval. In all, a very efficient mechanism. Just an idea I wanted to put out there. Thanks for getting it out. I have been contemplating the same for PostgreSQL but have been too lazy to do it myself ;) -- Hannu ___ 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 )

Ian Sparks wrote: Hannu, Does PostgresSQL allow you to have dynamic events? By this I mean can you do things like : PostEvent "Update_tblUsers_Record_" + new.RecordID; No, but it may change sometime (possibly soon) as PostgreSQL is an open-source product ... I believe that in Interbase the events are compiled into the trigger, not interpreted at Runtime so you can't have an Interbase event alert you to a change in a particular record, only that a change has occurred on a table. The same is true for postgrSQL, only the syntax is LISTEN/NOTIFY.

The metaphore seems quite right! Some of its most significant features (Aquiition, ExtensionClass) are even written in C and mess with guts of python interpreter. See for example PostgreSQL - it has C, SQL, PL/SQL, TCL, Perl, Ruby and soon python as its server-side programming languages, with no real argument about weather to include yet another language - if you dont want/need/know how to use it you just ignore it ;) And it was originally written in lisp ;-9 - Hannu ___ 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 )
