Original commit message from CVS:
* docs/random/ds/0.9-suggested-changes:
Add a note to change handoff use in fakesrc to be usable in
a more generic way (fakesrc should be renamed to appsrc or so).
* gst/elements/gstfakesrc.c: (gst_fakesrc_class_init):
Change signal type to scope, so we can fill the buffer in the
handoff handler (that's the whole use of this signal...).
Original commit message from CVS:
* gst/elements/gstbufferstore.c: (gst_buffer_store_get_buffer):
set the offset of the buffer to the requested offset
* gst/elements/gsttypefind.c: (stop_typefinding):
revert patch 1.18 (which I unfortunately don't know the reason for).
This is needed to allow downstream elements to seek. Otherwise
typefind might overwrite a previous seek by downstream elements.
This lead to errors with id3tag and typefind on some mp3s.
* gst/schedulers/entryscheduler.c: (COTHREADS_TYPE),
(gst_entry_scheduler_iterate):

Original commit message from CVS:
* gst/gstqueue.c: (gst_queue_init):
Reset default max. values in queues. Reason is simply to avoid
braindead use. If you want wider values, use the properties. The
default is supposed to always work. Wider values would make this
beast a memory hog by default (250 full-PAL RGB32 video frames?
That's 440 MB! No thank you).

2004-02-15 Julien MOUTTE <julien@moutte.net>
* gst/gstbin.c: (gst_bin_change_state), (gst_bin_iterate): Fix a big
bug that was breaking pipelines like sinesrc ! { queue ! osssink } when
an error was thrown by osssink. Basically a state change failure for
an element in a different scheduling group was considered as successfull , which means that caps nego was going on and weird stuff happened. Like i wrote in the comment there, if someone want to revert that please
drop me a mail explaining why because i really see no point in keeping
that broken behaviour there.
* gst/gstqueue.c: (gst_queue_get): Add a safety check as the queue CAN
be empty, we then return NULL which will trigger a nice error when
pulling from the pad.

* gst/gstdata.c: (gst_data_ref): Adding a categorized debug on data_ref
because data_unref has one and i prefer the debug to be symetric.
* gst/gstqueue.c: (gst_queue_locked_flush): Fix a huge memleak. Buffers
were refed when added to the queue and unrefed only once when the queue
was flushed. Now the flush handler unref the buffers two times : first
unref for the ref added when pushing in the queue's tail and second
unref to destroy the flushed buffer.
Original commit message from CVS:
Trying to fix the mess that I made with the two previous commits.
First commit, doing something wrong (fixing comparisons of signed and unsigned).
Second commit, trying to revert the previous, but changing other things and
reverting unrelated work of other people.
And this third, hopefully fixes it.

implement timeout for sending events. Workaround for if the
pipeline on this queue is not passing any data.
Original commit message from CVS:
Fix a deadlock that happens if the next element sends an event and the previous element sends a buffer where the queue is full. See the comment in the code for the rest.
Original commit message from CVS:
This is either a rewrite or a large bugfix to the queue element, whatever
you prefer to call it.
* upstream event forwarding now works. This should fix Julien's issues.
* this queue allows setting a min. treshold size and a max. limit size
in bytes, buffers and time before the queue allows the next element
to pull data or the previous element to push data into it. This is
very interesting for network-related buffering. Also includes signals
et all for the end user application.
* Events are no longer part of the queue's "size", they're essentially
seen as "void data". they have no size or time associated with them
anyway, so this shouldn't really sound weird.
