Debian updated package 4.2
by Fredrik Unger 05 Mar '14

05 Mar '14

Hi, I updated my personal package to 4.2. https://tree.se/debian/ There were three minor changes, fixing a few SQL statements for 0.1.4, adding python-psutil as dependency, debianizing PGSOCKETDIR. I will improve on packaging, this was the first attempt. The server starts and http://localhost:8008/ works in the browser. Not tested any further. Not a SAFE upgrade path, and it might eat your cat. It is for testing on a empty server without any important data. With regards to the SQL patch. Looking at trunk some of these SQL statements are OK for 0.1.4, some are not. It is the same problems with 'primary key(' and 'unique(' as in Ticket #759. http://trac.calendarserver.org/ticket/759 Example from current trunk (r10297) is line 186 vs 192. http://trac.calendarserver.org/browser/CalendarServer/trunk/txdav/common/da… Still not a big deal and calendar server does not support 0.1.4, but 0.1.2 http://trac.calendarserver.org/browser/CalendarServer/trunk/support/build.s… Not sure it makes sense to open a bug against the SQL issue as new code got added with 'primary key(' sql. It is after all a sqlparse bug. Better for packagers to patch it I think, as the distribution is using the "wrong" version. To fix it is just to add a space, and the issues is now well known. Thanks /Fred

PyKerberos - Python 3 support patch
by Alex Szczuczko 26 Apr '13

26 Apr '13

Hello, About two months ago I submitted an Enhancement patch for the PyKerberos component under Ticket #798 [1]. This patch is described in detail on the ticket, but essentially it introduces support for Python 3 while maintaining support for Calendar Server's minimum Python version of 2.6 [2]. Since I haven't heard anything, I thought I would request feedback for the patch directly. I have done some basic testing of the patch, but if there's more that I need to do to get it included, please let me know. Thanks, Alex Szczuczko [1] - https://trac.calendarserver.org/ticket/798 [2] - http://trac.calendarserver.org/wiki/HACKING#coding-standards

Github mirror of CalDAVClientLibrary and submitting patches
by Sriram Karra 23 Apr '13

I have been using the client library to add CardDAV suppport to ASynK - a bidirectional sync tool that now works with Google Contacts, MS Outlook, Emacs BBDB, and now CardDAV. You can find more about asynk at http://karra-asynk.appspot.com/ I have had to patch the latest code available from SVN. I have mirrored the official tree in the following repo: https://github.com/skarra/CalDAVClientLibrary and pushing my changes to the the 'asynkdev' branch ( https://github.com/skarra/CalDAVClientLibrary/tree/asynkdev) I would like to submit some of my patches back to the mainline. What would be the best way to do that? The most important addition I have made is the implementation of a MulitGet for CardDAV. -Karra
