[PHPiCalendar-DEV] Activity in CVS - 2.25 release being worked on.

[Jim Hu <ji...@ta...>]

I haven't gotten very far with version 3, but I got sick of some of  
the outstanding bugs and made a major change in cvs that will be the  
basis for 2.25.  The big changes

- handling the END:VEVENT has been split out of ical_parser.php into  
a separate file called end_vevent.php

- I am trying to reduce the number of places in the code where the  
master_array gets written.  I got rid of a couple by going toward my  
plan for v3, which is to treat all events as recurring, but allow  
only one instance for a non-recurring event.  Right now this is  
implemented with a kind of ugly hack.

- I reduced the size of the master_array for the day, week, and month  
views.  This may break save_parsed_cals, but I haven't tested that  
yet.  The hope is to reduce the problems people have been having with  
memory overflows.

- I started working on adding support for the TZ_IDs in ics files  
that aren't in our canned list.  Right now this is being done by  
reading the ics file twice, which is probably a bad idea.  The two  
passes are to deal with tz info being at the end of the file.  But  
I'm thinking that a better approach is to load a heavily pruned  
master_array first, then traverse it and adjust the timezone info  
before sorting.  This could be ugly, though, as some of the  
adjustments will alter the date and time keys, and I'm not sure about  
how the overlap handling will cope.

In case anyone on the list is still thinking about phpical now and  
then, I'd love to have people look at what's going on!  I'm thinking  
that I probably broke stuff that worked in Chad's code in the process  
of making all these changes.

Also, in an earlier part of the 2.x development, I tried to change  
the strtotime statements to make them less sensitive to strtotime  
bugs in certain php installations.  In hindsight, I'm not sure if  
that was a good idea, as it causes problems in daylight savings  
transitions.  Discussion of this would be welcome.
