12 2010-09-18T13:12:29 <ThomasWaldmann> (but i didn't commit it, it was caching the complete internal_representation, which is a bit too much)

17 2010-09-18T14:47:55 <valeuf> long time no see ^^ I have been pretty busy last days, but I am back in the business
18 2010-09-18T14:49:27 <valeuf> I understood the problem with the bug, I wrote a quick fix, however it is not really clean

22 2010-09-18T14:52:25 * dreimark much :)
23 2010-09-18T14:54:39 <valeuf> I am happy to see that things are going well, I will try to get back on the path
24 2010-09-18T14:57:14 <xorAxAx> valeuf: i havent submitted the linkedin thingie yet, but its still on my todo list

36 2010-09-18T18:45:40 <ThomasWaldmann> hmm, we maybe have a problem with cache keys
37 2010-09-18T18:46:51 <ThomasWaldmann> moin uses (used) a trick to avoid doing acl checks for stuff sent from the cache
38 2010-09-18T18:47:43 <ThomasWaldmann> it generates the cache access keys involving a server secret, so the user can't compute an access key without the help from server
39 2010-09-18T18:48:14 <ThomasWaldmann> (this is what one sees as from_cache=... value in the url for such cases)
40 2010-09-18T18:49:24 <ThomasWaldmann> but caches (like the stuff from werkzeug, flask-cache) don't assure that stuff is available, not even for some specific time
41 2010-09-18T18:49:43 <ThomasWaldmann> an object can basically be gone any time and the cache returns None then
42 2010-09-18T18:50:35 <ThomasWaldmann> but if that cache key was all we have, there's no way to re-compute the content
43 2010-09-18T18:51:58 <ThomasWaldmann> that can be solved by giving all params needed to compute the content
44 2010-09-18T18:52:57 <ThomasWaldmann> but if that works in some obvious way that can be done by user, he basically has an access method for that content and we'ld need to check acls
45 2010-09-18T18:53:35 <ThomasWaldmann> any other idea than using symmetric encryption?
46 2010-09-18T18:59:18 <dreimark> re
47 2010-09-18T19:03:54 <ThomasWaldmann> (if the method is too expensive, we might be better off with just checking acls)
48 2010-09-18T19:04:08 <dreimark> not yet, but i am also not sure if encryption is enough or how to do it safe enough
49 2010-09-18T19:04:41 <dreimark> no cache - no problems
50 2010-09-18T19:05:25 <ThomasWaldmann> :) yes, but maybe not what one wants for thumbnails and similar stuff
51 2010-09-18T19:06:28 <dreimark> maint cleancache and recreating is neccessary if the secret becomes changed
52 2010-09-18T19:07:15 <dreimark> how slow is an acl check?
53 2010-09-18T19:07:49 <ThomasWaldmann> i have no specific numbers, but slower than doing none :)
54 2010-09-18T19:08:15 <dreimark> we may be could also use the tar item
55 2010-09-18T19:08:37 <ThomasWaldmann> needs opening of item metadata (or later maybe getting that from index) and computing may.read for that user
56 2010-09-18T19:09:13 <dreimark> e.g .if a tar item has the image and a thumbnail etc. then we need to check only once acls
57 2010-09-18T19:09:31 <dreimark> and the whole container can be accessed
58 2010-09-18T19:10:02 <ThomasWaldmann> yes, but at next request, you need to check again (and we are talking about multiple requests)
59 2010-09-18T19:10:34 <dreimark> true. but we need to check access for the item anyway
60 2010-09-18T19:10:51 <ThomasWaldmann> well, I guess there is no real choice. :|
61 2010-09-18T19:11:21 <ThomasWaldmann> i guess i have to implement acl check and do caching the more usual way.
62 2010-09-18T19:13:00 <ThomasWaldmann> waldi: TheSheep: any other ideas before i do that?
63 2010-09-18T19:13:27 <dreimark> i think too it needs to be checked on item level. may be we can cache somehow the result if many items are used from one item
64 2010-09-18T19:13:52 <ThomasWaldmann> that is just asking for more trouble X)
65 2010-09-18T19:14:28 <ThomasWaldmann> but maybe index with cache would be nice
66 2010-09-18T19:14:28 <dreimark> probably yes
67 2010-09-18T19:14:54 <ThomasWaldmann> ehrm, index with acls
68 2010-09-18T19:16:25 <dreimark> that would make it possible to show what a user can do or has access to
69 2010-09-18T19:16:55 <dreimark> faster

72 2010-09-18T21:18:23 <RaphaelBossek> hi folks; I've cloned 2.0-dev looking for the interface where to integrate a possible formater for PDF
73 2010-09-18T21:21:32 <dreimark> ThomasWaldmann: valeuf ^
74 2010-09-18T21:24:54 <dreimark> RaphaelBossek: in principle you need to write a convertor pdf_out
75 2010-09-18T21:25:12 <dreimark> see converter2
76 2010-09-18T21:26:09 <RaphaelBossek> I've started MoinMoin at localhost:8080 and would like to try some of those convertes out, but how ?
77 2010-09-18T21:27:38 <dreimark> create an item by appending an item name to the url
78 2010-09-18T21:28:23 <RaphaelBossek> could you please continue this link if I want DOCBOOK ? http://localhost:8080/Home
79 2010-09-18T21:30:54 <dreimark> see here http://moinmo.in/DOM%20DocBook%20and%20HTML%202010/DocBook%20Converter

84 2010-09-18T21:32:58 <RaphaelBossek> dreimark, I would like to convert the http://localhost:8080/Home page to DOCBOOK in order to go through the code with my debuger
85 2010-09-18T21:33:21 <dreimark> i know but i can't help much just pointing on documentations
86 2010-09-18T21:33:36 <dreimark> valeuf: would be the best choice for QA
87 2010-09-18T21:33:45 <dreimark> ThomasWaldmann: may be able to help too
88 2010-09-18T21:33:46 <RaphaelBossek> dreimark, it would be helpful to have an action menu item to select the converter2 plugins
89 2010-09-18T21:34:43 <RaphaelBossek> ThomasWaldmann, try to investigate the possibilities to integrate a PDF converter2 plugin using http://www.reportlab.com/software/opensource/rl-toolkit/download/ for MoinMoin 2.0

120 2010-09-18T22:31:36 <CIA-36> the case). Cache key must not be guessable, no ACL check needed to read the
