- Set reading_pos correctly in _create_read ()
- Seek to data if it is further than QUEUE_MAX_BYTES (queue) -
cur_level.bytes away. This should avoid a situation where the ring
buffer is full but the data offset from which we shall read is not in
the ring buffer.
- Only update the max_reading_pos to a lower value to protect data when
necessary
- Always signal an ADD in _locked_enqueue () so that an EOS unlocks the
reader
- More useful debug output
update_buffering () needs to be called every time we write to the ring
buffer so that applications don't get stuck waiting for a 100% buffered
message while queue2 is waiting for space
_create_write () must only be called for temp file/ring buffer cases
Cached data could have been overwritten so it is now protected until
it is read. Similarly data was overread as _have_data () was always
looking for the originally requested data even if part of it had been
read already.
Use cur_level.bytes to see how much space is free in the ringbuffer.
Simplyfy the write function, avoid taking subbuffers, move waiting for free
space in one spot, use simply counter to write data of a buffer.
- make _get_range () emit the del signal once a buffer has been read
- use do {} while (); for wait code as queue is locked and no data could
have been read in the mean time so it makes no sense to check before
waiting
- make _is_filled () more robust
Current range was being updated in the thread performing seek, but as
no locks were kept for a short section, data flow could resume before
current range updated, so data for the new range would be accepted as
from the previous range.
Rather, range should be updated in serialized manner based on
newsegment event.
Don't override the default get_times vmethod so that we can use the sync
property.
Set the default sync property to FALSE. It used to be set to TRUE but because
the get_times was NULL, it always behaved like FALSE.
Fixes#621530
Implement a custom acceptcaps function. We can simply check if there is an
intersection with the new caps. This makes the accept caps function much faster.
See #621190
