| nxf | Hi folks, I'm new to Zope in general, and trying to evaluate Z2 and Z3. I want to write a small web app to start with, not requiring Plone or anything, but I like the portal_skins feature from CMFCore in Z2. Would you recommend to jump directly into Z3 or first get familiar with the Z2 way of doing things? | 13:16 |
| ccomb | If you want to use just zope, jump directly into Z3 | 13:18 |
| ccomb | If you want a full featured CMS, jump into Plone, and try to use Five as much as possible | 13:18 |
| ccomb | (that's my opinion) | 13:18 |
| ccomb | You already have some skinning features and form generation in Z3 | 13:19 |

| philiKON_ | d2m: the zodb is locked when the database is opened | 21:00 |
| philiKON_ | this happens when zope starts up | 21:01 |
| philiKON_ | in your case you seem to be starting multiple zopes | 21:01 |
| philiKON_ | because, for example, mod_python/mod_wsgi start multiple python interpreter | 21:01 |
| philiKON_ | at least one per apache process | 21:01 |
| philiKON_ | you probably want to use zeo here | 21:01 |
| d2m | ok, i'll try, thanks for the tip | 21:02 |
| d2m | err, hint | 21:02 |
| philiKON_ | however, last time i wanted to use zeo within apache, i had problems | 21:03 |
| d2m | i haven't had that kind of problem with a wsgi server so far | 21:04 |
| d2m | philiKON_: works now, and its double the speed than with the local Data.fs | 21:17 |

| philiKON_ | but apache typically is multi-processed | 21:19 |
| d2m | so, i'm getting now 120 req/sec ofZope3+ZEO, on a station that makes 2500 req/sec on a static file with apache | 21:22 |
| d2m | i think the resulting will be a 2 to 3 times increase over the builtin server | 21:26 |

| derek|laptop | does anyone know how to populate a field on an annotation with the return value of a function upon annotation creation? I tried doing it in the annotation impl class, but that seems to be ignored. I also looked at doing it in the schema, but the arguments for TextLine AFAICT only allow literal default values that apply to all instances of the annotation, not a default value generated by a function that will be different for each annotation instance.. | 21:53 |
| *** alecm has quit IRC | 21:57 | |
| philiKON | are you usnig zope.annotation.factory? | 21:57 |
| derek|laptop | yes | 21:57 |
| philiKON | then why aren't you simply setting those default values in __init__? | 21:57 |
| derek|laptop | that's a good question. the answer must be: because I was looking for something harder. :) I'll do that. Thanks, philiKON! | 21:58 |

| d2m | btw, where do zcml files inside a WSGIApplication object get their path information from ? in a first run i was forced to change all relative paths in .conf and .zcml files to absolute paths | 22:03 |
| d2m | setting sys.path is not good enough | 22:03 |
| philiKON | paths are assumed to be relative | 22:04 |
| philiKON | in zcml | 22:04 |
| philiKON | relative to a package, usually | 22:04 |
| d2m | thats a bit of a problem | 22:04 |
| d2m | ok, maybe its the .conf files only that need abolute paths to e.g. site.zcml | 22:05 |
| philiKON | well, or relative paths to cwd | 22:05 |

| philiKON | jim was that | 22:23 |

| sm | good morning all | 22:38 |
| d2m | hi sm | 22:38 |
| sm | I'm having a serious problem with zope 3's tal in zope 2.10.3 | 22:38 |
| sm | tal:content="structure var" seems to require that var be ascii, in z3 tal ? | 22:39 |
| lurker | sm, z3 zpt are unicode | 22:42 |
| lurker | so if you pass string it will be converted, and ascii is the default converter | 22:42 |
| sm | ah.. how is the converter configured ? | 22:44 |
| benji | jodok: in some tests with a Zope 2 app we saw around an 80% increase of memory footprint when going from 32 to 64 bit | 22:45 |
| jodok | benji: unfortunately i don't know enough what happens behind the (python) scenes | 22:46 |
| jodok | but i'd like to know a little bit more :) | 22:47 |
| benji | it's pretty simple really, pointers are twice as big and any app that is pointer-heavy (like CPython) will see large increases in memory usage | 22:48 |
| jodok | and they are bigger because they can address more memory, right? | 22:48 |
| benji | one thing we considered and tested (but have not yet done in production) is to run 32-bit apps on a 64-bit OS; if a single process doesn't need to access huge amounts of ram (or do 64-bit integer operations), you can get the best of both worlds | 22:49 |
| benji | right | 22:49 |
| benji | you're probably thinking of the plugin for Zope 2 that gives basic monitoring info (memory usage, active connections, etc.); Jim recently started something like that for Zope 3 too (looking up URL) | 22:52 |
| benji | I don't know if it's usable yet, but here it is: http://svn.zope.org/zc.z3monitor/ | 22:52 |

| sm | in #python they tell me the default system encoding used by unicode() is just a bad idea and will go away in python 3, and encoding should always be specified | 23:13 |
| *** d2m has left #zope3-dev | 23:14 | |
| benji | sm: I know next to nothing about unicode, but believe both those statements to be true. | 23:17 |

| sm | the reason I care is I'm trying to make zwiki work with both zope 2.9 and 2.10. The z3 tal in 2.10 calls unicode() using default encoding on my content. | 23:17 |
| sm | since I can't/may not influence that default encoding, it seems I should just ensure my content is unicode before tal sees it | 23:18 |
| sm | but only when the zope version is 2.10 or greater.. | 23:18 |
| benji | why not on z3 as well? | 23:19 |
| sm | well, z3 zwiki is a whole different codebase | 23:20 |
| sm | do you mean why not make the zope2 zwiki work on z3 also ? is that a sane thing to try ? | 23:20 |
| sm | surely not | 23:20 |
| benji | oh, I thought they were the same code | 23:27 |
| sm | alas no, totally different projects | 23:28 |
| sm | so: I would think that this should work: if ZOPEVERSION > 2.10: arg = unicode(arg,myencoding); template(self,REQUEST,option1=arg) | 23:33 |
| sm | but it does not. still getting that fricking unicodedecodeerror :) | 23:36 |
| benji | this is where my statement of "I know next to nothing about unicode" comes back to help me and haunt you ;) | 23:39 |
| pbugni | sm - any chance the error is coming from the line above: arg = unicode(arg,myencoding); ? | 23:40 |
| pbugni | this tends to be my trouble - not knowning what encoding it is coming from | 23:41 |
| pbugni | or knowing | 23:41 |
| sm | no, the conversion to unicode works | 23:41 |
| sm | it's just when I call the template (and it applies the structure keyword to option1) | 23:41 |
| sm | http://paste.lisp.org/display/40519 | 23:43 |
| pbugni | 'ascii' codec .... how do you alert it to the fact you already have unicode? <tal:content="python: type(body)"/> | 23:47 |
| pbugni | you want <type 'unicode'> there, i would expect | 23:48 |
| pbugni | and i'm guessing that isn't happening - thinks it's <type 'str'> | 23:48 |
| sm | ah-haaa.. the error is coming from another part of the template, using some other piece of data | 23:49 |
| pbugni | that's good news :) | 23:49 |
| sm | fortunately, I don't need to alert it that I'm giving it unicode - unicode(unicode()) seems to be a noop | 23:49 |
| pbugni | y - but unicode(ascii str) is not | 23:50 |
| pbugni | before you realized it was coming from a different part of the template, i assumed it was a type issue | 23:50 |
| sm | yes, good news.. so I have to apply this same workaround anywhere I pass in data used with the structure keyword | 23:52 |
| sm | progress | 23:52 |
| pbugni | or tal:content='structure python:unicode(var)', right? | 23:52 |
| pbugni | < myencoding | 23:53 |
| sm | yes, I think so. but I have to do it only for zope >= 2.10 | 23:54 |
