Jeffrey P Shell: PythonPython related programming topicsAha! (Python Patch)- July 18, 2002 So, the mysterious core dumps seem to be over, thanks to this patch on SourceForge.net regarding pthreads and stack sizes on BSD. I reverted back from the Tracker changes I made last night, and nothing crashed. I did have to make one small patch to Tracker though, introducing a fun filled positive lookahead assertion to a regular expression used to generate HREF's.http://radio.weblogs.com/0106123/categories/python/2002/07/17.html#a158 Issue Trackers Revisited- July 17, 2002 So finally, I have "Tracker" working with "Zope" 2.5.1 and "Python" 2.1.3 on FreeBSD 4.5. It seems that the restricted Python engine (which I presume is newrevamped in 2.5) has a problem with expressions that are heavy with parenthesis. So, after crawling through a lot of DTML code (some of it quite old - some of it predating the 'let' tag!) by slowly moving a 'dtml-raise' statement around, I was able to find all (or at least most) of my problems. I just couldn't take "Roundup" any more. ...http://radio.weblogs.com/0106123/categories/python/2002/07/16.html#a157 An optimization dilemma- July 8, 2002 I'm facing a nice little PythonZope programmers dilemma. I have a critical "Zope" "Python" Script - Python code objects in Zope that are editable through the web, and are subject to being run in a "restricted mode" interpreter that enforces Zope security policies. It's quite long for a single script, weighing in at approximately 170 lines. But it does its job well, and is written with maintainability in mind (there's only one variable in there that I find non-obvious, and whose usage I might.http://radio.weblogs.com/0106123/categories/python/2002/07/08.html#a153 Customizing Roundup, day one- July 2, 2002 I spent some more time working with "Roundup" this morning. When you create a new instance, one of the files it generates is dbinit.py. dbinit.py contains code to initialize the database schema, and also contains an empty IssueClass class, subclassed off of the default roundup.roundupdb.IssueClass. I was able to take advantage of this to customize the emails sent out by "Roundup" to make them look a bit more like the ones sent out by Tracker (as mentioned in the "Python based Issue Trackers".http://radio.weblogs.com/0106123/categories/python/2002/07/02.html#a150 Python based Issue Trackers- July 2, 2002 I've been on one end or another of three Python based issue trackers lately - Tracker, its descendant, CMFCollector, and it's competition in the Software Carpentry contest, Roundup. And there's always something there to make me unhappy. Tracker is one of the best issue trackers I have used. It's got a fairly solid user interface, a fairly solid built in Workflow, and hierarchical correspondencestate changing. It's one of the easiest web based issue tracking systems to use to follow the...http://radio.weblogs.com/0106123/categories/python/2002/07/01.html#a149 |
