- Bumped all version numbers to 2.2.0.
- Official release.
2015-04-29: Version 2.3.1
2015-09-01: Version 2.3.1
- The new function cOsd::MaxPixmapSize() can be called to determine the maximum size
a cPixmap may have on the current OSD. The 'osddemo' example has been modified
@ -8671,3 +8671,114 @@ Video Disk Recorder Revision History
this VDR is connected to via SVDRP.
- The new class cSVDRPCommand can be used to execute an SVDRP command on one of
the servers this VDR is connected to, and retrieve the result.
- The cTimer class now has a new member named 'remote', which holds the name of the
remote server this timer will record on. If this is NULL, it is a local timer.
- Timers from other VDRs that are connected to this VDR via SVDRP are now
automatically fetched and stored in the global Timers list. In order for this
to work, all of the channels used by timers on the remote VDR must also be
defined on the local VDR (however, not necessarily in the same sequence).
Automatic channel syncing will be implemented later.
- The main menu of the LCARS skin now displays a small rectangle on the left side
of a timer if this is a remote timer. The color of that rectangle changes if
the timer is currently recording on the remote VDR.
- Accessing the global Timers list now has to be protected by proper locking,
because SVDRP commands are now executed in a separate thread.
The introduction of this locking mechanism required the following changes:
+ The new classes cStateLock and cStateKey are used to implement locking
with quick detection of state changes.
+ cConfig::cConfig() now has a parameter that indicates whether this list
requires locking.
+ The global lists of Timers, Channels, Schedules and Recordings are no longer
static variables. They are now pointers that need to be retrieved through
a call to cTimers::GetTimersRead/Write(), cChannels::GetChannelsRead/Write(),
cSchedules::GetSchedulesRead/Write() and cRecordings::GetRecordingsRead/Write(),
respectively.
+ References from/to link channels are now removed in cChannels::Del() rather
than cChannel::~cChannel(), to make sure the caller holds a proper lock.
+ cChannel::HasTimer() has been removed. This information is now retrieved
via cSchedule::HasTimer().
+ Several member functions of cChannel, cTimer, cMarks and cRecording have
been made 'const', and some of them are now available as both 'const' and
'non-const' versions.
+ The cChannel::Set...() functions are now 'bool' and return true if they have
actually changed any of the channels's members.
+ cChannels::SetModified() has been renamed to cChannels::SetModifiedByUser().
+ cChannels::Modified() has been renamed to cChannels::ModifiedByUser(), and
now has a 'State' parameter that allows the caller to see whether a channel
has been modified since the last call to this function with the same State
variable.
+ The macros CHANNELSMOD_NONE/_AUTO/_USER have been removed.
+ cMarks now requires locking via cStateKey.
+ cSortedTimers now requires a pointer to the list of timers.
+ cEvent::HasTimer() no longer scans the list of timers to check whether an event
is referenced by a timer, but rather keeps score of how many timers reference
it. This was necessary in order to avoid having to lock the list of timers from
within a cEvent.
+ The new class cListGarbageCollector is used to temporary store any objects deleted
from cLists that require locking. This allows pointers to such objects to be
dereferenced even if the objects are no longer part of the list.
+ cListBase::Contains() can be used to check whether a particular object is still
contained in that list.
+ Outdated events are no longer "phased out", but rather deleted right away and thus
taken care of by the new "garbage collector" of the list.
+ Deleted cRecording objects are no longer kept in a list of "vanished" recordings,
but are rather taken care of by the new "garbage collector" of the list.
+ cSchedules::ClearAll() has been removed. The functionality is now implemented
directly in cSVDRPServer::CmdCLRE().
+ tEventID has been changed to u_int16_t in order to make room for the new member
numTimers in cEvent.
+ cSchedule now has a member Modified(), which can be used with a State variable
to quickly determine whether this schedule has been modified since the last call
to this function with the same State variable.
+ cSchedulesLock has been removed. Locking the list of schedules is now done via
the cList's new locking mechanism.
+ The 'OnlyRunningStatus' parameters in cEpgHandler::BeginSegmentTransfer() and
cEpgHandler::EndSegmentTransfer() are now obsolete. They are still present in
the interface for backward compatibility, but may be removed in a future version.
Their value is always 'false'.
+ The constant tcMod is no longer used in cStatus::TimerChange(). The definition is
still there for backward compatibility.
Plugins that access the global lists of Timers, Channels, Recordings or Schedules
will need to be adapted as follows:
+ Instead of directly accessing the global variables Timers, Channels or Recordings,
they need to set up a cStateKey variable and call the proper getter function,
as in
cStateKey StateKey;
if (const cTimers *Timers = cTimers::GetTimersRead(StateKey)) {
// access the timers
StateKey.Remove();
}
and
cStateKey StateKey;
if (cTimers *Timers = cTimers::GetTimersWrite(StateKey)) {
// access the timers
StateKey.Remove();
}
See timers.h, thread.h and tools.h for details on this new locking mechanism.
+ There are convenience macros for easily accessing these lists without having
to explicitly set up a cStateKey and calling its Remove() function. These macros
have the form LOCK_*_READ/WRITE (with '*' being TIMERS, CHANNELS, SCHEDULES or
RECORDINGS). Simply put such a macro before the point where you need to access
the respective list, and there will be a pointer named Timers, Channels, Schedules
or Recordings, respectively, which is valid until the end of the current block.
+ If a plugin needs to access several of the global lists in parallel, locking must
always be done in the sequence Timers, Channels, Recordings, Schedules. This is
necessary to make sure that different threads that need to lock several lists at
the same time don't end up in a deadlock.
+ Some pointer variables may need to be made 'const'. The compiler will tell you
about these.
- cSectionSyncer has been improved to better handle missed sections.
- Added a missing initialization of 'seen' in cChannel's copy constructor.
- Background modifications of channels, timers and events are now displayed immediately
in the corresponding menus.
- cEIT now checks the version of the tables before doing any processing, which saves
a lot of locking and processing.
- If a timer is newly created with the Red button in the Schedule menu, and the timer
is presented to the user in the "Edit timer" menu because it will start immediately,
it now *must* be confirmed with "Ok" to set the timer. Otherwise the timer will not
be created.
- Recordings and deleted recordings are now scanned in a single thread.
- The new SVDRP command POLL is used by automatically established peer-to-peer
connections to trigger fetching remote timers.
- You can now set DumpSVDRPDataTransfer in svdrp.c to true to have all SVDRP
communication printed to the console for debugging.
