/**
* Class to access AND manipulate all calendar data (business object)
*
* The new UI, BO and SO classes have a strikt definition, in which time-zone they operate:
* UI only operates in user-time, so there have to be no conversation at all !!!
* BO's functions take and return user-time only (!), they convert internaly everything to servertime, because
* SO operates only on server-time
*
* As this BO class deals with dates/times of several types and timezone, each variable should have a postfix
* appended, telling with type it is: _s = seconds, _su = secs in user-time, _ss = secs in server-time, _h = hours
*
* All new BO code (should be true for eGW in general) NEVER use any $_REQUEST ($_POST or $_GET) vars itself.
* Nor does it store the state of any UI-elements (eg. cat-id selectbox). All this is the task of the UI class(es) !!!
*
* All permanent debug messages of the calendar-code should done via the debug-message method of the bocal class !!!

SyncML patches from patrick.bihan-faou-AT-mindstep.com (without logout+mbstring stuff), small modification to use the already exiting methodes to generate full name and fileas) The code is commited to trunk only at the moment to allow testing of it. If everything goes well, we intend to commit it to 1.4 branch too. Here's the original description of the patch by Patrick: - handles the default config for current versions of funambol (i.e. the scard/stask/snote/scal locations) - tries to be a bit smarter on how the data content should be encoded based on what the client specified (sif+base64/vcard, / fragmented or not, etc.) - workaround a bug in some versions of funambol, where funambol does not specify the proper sif type for the type of requested data - imported patch #117 from egw's tracker - make sure that the logs generated by the horde code go to stderr so they can be view in the webserver's logs - as much as possible reduce code duplication. For example, the categories are handled in the parent classes for both the SIF avn VCAL formats for each type of data (addressbook,infolog,calendar). - make sure the code can handle more than one categories in each direction - treat the 'sony ericsson' vendor string just like 'sonyericsson', the newer phones apparently have a space in the vendor string... (this touches some files in the icalsrv as well) - handle notes: these should now work with everything (funambol or other) - remove more code duplication: the syncml "api" for the various data types (calendar, contacts, infolog) is now common for both the vcard and sif data formats (cf the files that need to be removed) - handle the "privat" filter in infolog like the "private" filter (some part of the code use the name without the trailing e) - imported patch # 267 from egw's tracker

SyncML patches from patrick.bihan-faou-AT-mindstep.com (without logout+mbstring stuff), small modification to use the already exiting methodes to generate full name and fileas) The code is commited to trunk only at the moment to allow testing of it. If everything goes well, we intend to commit it to 1.4 branch too. Here's the original description of the patch by Patrick: - handles the default config for current versions of funambol (i.e. the scard/stask/snote/scal locations) - tries to be a bit smarter on how the data content should be encoded based on what the client specified (sif+base64/vcard, / fragmented or not, etc.) - workaround a bug in some versions of funambol, where funambol does not specify the proper sif type for the type of requested data - imported patch #117 from egw's tracker - make sure that the logs generated by the horde code go to stderr so they can be view in the webserver's logs - as much as possible reduce code duplication. For example, the categories are handled in the parent classes for both the SIF avn VCAL formats for each type of data (addressbook,infolog,calendar). - make sure the code can handle more than one categories in each direction - treat the 'sony ericsson' vendor string just like 'sonyericsson', the newer phones apparently have a space in the vendor string... (this touches some files in the icalsrv as well) - handle notes: these should now work with everything (funambol or other) - remove more code duplication: the syncml "api" for the various data types (calendar, contacts, infolog) is now common for both the vcard and sif data formats (cf the files that need to be removed) - handle the "privat" filter in infolog like the "private" filter (some part of the code use the name without the trailing e) - imported patch # 267 from egw's tracker
