davisagliTresEquis: what's this picklecache branch? getting rid of ZODB's dependence on CPython?00:16
TresEquistrying to, anyway00:16
TresEquisI *think* that there is enough support for trickery now to make the C bits an optimization00:16
TresEquisgiven __slots__, weakrefs, etc.00:17
TresEquisI already reimplemented the picklecache00:17
TresEquisworking on the Persistent base class now00:18
davisagliright, seems like it's worth a try at least00:20
TresEquisI'm about to get to the place where I try to bring the two together00:21
TresEquislike the transcontinental railroad00:21
TresEquisI just hope the two lines are at least in the same county ;)00:21
TresEquisI might even get the RAM footprint down00:22
davisaglihow? slots?00:22

betabughahaha, no way11:43
betabugups, err# on the last one11:43
d2mit feels pretty useless these days, timeouts at login et al.11:43
betabugI'm not logging in11:43
d2mcould be the only way to use it in the moment11:43
betabugI haven't logged in in something like 5 years11:44
betabugd2m: you're thinking of switching it off (or switching it over to
d2mas you might now we are in the process to replace it with a new front, a hub site that gets you links to all single websites that feature the different aspects of zope11:45

hariomHi, I am fetching some values from database via zsql script and showing it on a page. In zmi, I see that zsql script runs fine and returns values. When I run the page, I get TraversalError on a particular field value fetched from the database. What could be the reason?12:42
betabughariom: put the full traceback on a pastebin, maybe someone can see what's wrong12:45
betabugmodern zopes show all kind of stuff as TraversalError and the real problem is hidden in the traceback12:46

CIA-85icemac * r120375 /zope.testrunner/branches/icemac-lp-719369: added branch to handle unexpected successes12:55
CIA-85icemac icemac-lp-719369 * r120376 zope.testrunner/ (6 files in 3 dirs): An `Unexpected success` (concept intruduced in Python 2.7) is no longer handled as success but as failure. This is a workaround. The whole unexpected success concept might be implemented later.12:55

hariomI get error if I write this:      and the error is: missing FROM-clause entry for table "rt" LINE 16: rt.num_seats13:19
hariomIf I remove <dtml-if ...> clause from join on table1.ring_tables I get no errors. Why is it so?13:21
