6d87ece93d gst/elements/gstbufferstore.c: set the offset of the buffer to the requested offset
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):
be more verbose when debugging

097dc18c80 gst/gstpad.c: print caps in debugging output when setting caps failed
Original commit message from CVS:
* gst/gstpad.c: (gst_pad_set_explicit_caps):
print caps in debugging output when setting caps failed
* gst/schedulers/entryscheduler.c: (COTHREADS_TYPE),
(schedule_next_element), (get_buffer), (run_chainhandler),
(element_may_start), (gst_entry_scheduler_chain_handler),
(gst_entry_scheduler_get_handler),
(gst_entry_scheduler_state_transition),
(gst_entry_scheduler_pad_link):
make this scheduler a testcase for mandatory
discont-before-first-buffer which is needed if we want to allow apps
to release the sound device.
add SCHED_ASSERT macro to print scheduler state before an assertion
triggers.

Original commit message from CVS:
* gst/gstbin.c: (gst_bin_set_element_sched),
(gst_bin_unset_element_sched):
don't add decoupled elements to schedulers - otherwise it's
impossible to control if a link to a decoupled element was already
removed from a scheduler or not.
* gst/schedulers/cothreads_compat.h:
* gst/schedulers/gthread-cothreads.h:
add COTHREADS_TYPE macro. Make do_cothread_set_func a macro so there
is no "unused" warning.
* gst/schedulers/Makefile.am:
* gst/schedulers/entryscheduler.c:
add new scheduler, based on ideas from talking to David and Martin.
It's supposed to be small and correct. Currently it's also slow (but
it's not noticable)
* examples/retag/retag.c: (main):
* testsuite/bytestream/test1.c: (main):

b6a5699ca6 gst/gstbin.c (gst_bin_remove): Debugging fixes.
Original commit message from CVS:
2004-03-07  Andy Wingo  <wingo@pobox.com>

* gst/gstbin.c (gst_bin_remove): Debugging fixes.

* gst/schedulers/gstoptimalscheduler.c (destroy_group): Assert
there are no links to other groups when a group is destroyed.
(gst_opt_scheduler_pad_unlink): If the unlink means an element is
removed from a group, make sure the link count to elements linked
to other pads is appropriately decremented. This really fixes
#135672.

The 1.60->1.61 patch has been reapplied in light of this fix.

* gst/gstelement.c (gst_element_dispose): Really protect against
multiple invocations this time.

Original commit message from CVS:

* gst/gstelement.c (gst_element_dispose): Protect against multiple
invocations.

* gst/schedulers/gstoptimalscheduler.c
I added a mess of prototypes at the top of the file by way of
documentation. Some of the operations on chains and groups were
re-organized.

(create_group): Added a type argument so if the group is enabled,
the setup_group_scheduler knows what to do.
(group_elements): Added a type argument here, too, to be passed on
to create_group.
(group_element_set_enabled): If an unlinked PLAYING element is
added to a bin, we have to create a new group to hold the element,
and this function will be called before the group is added to the
chain. Thus we have a valid case for group->chain==NULL. Instead
of calling chain_group_set_enabled, just set the flag on the group
(the chain's status will be set when the group is added to it).
(gst_opt_scheduler_state_transition, chain_group_set_enabled):
Setup the group scheduler when the group is enabled, not
specifically when an element goes PAUSED->PLAYING. This means
PLAYING elements can be added, linked, and scheduled into a
PLAYING pipeline, as was intended.
(add_to_group): Don't ref the group twice. I don't know when this
double-ref got in here. Removing it has the potential to cause
segfaults if other parts of the scheduler are buggy. If you find
that the scheduler is segfaulting for you, put in an extra ref
here and see if that hacks over the underlying issue. Of course,
then find out what code is unreffing a group it doesn't own...
(create_group): Make the extra refcount floating, and remove it
after adding the element. This means that...
(unref_group): Destroy when the refcount reaches 0, not 1, like
every other refcounted object in the known universe.
(remove_from_group): When a group becomes empty, set it to be not
active, and remove it from its chain. Don't unref it again,
there's no floating reference any more.
(destroy_group): We have to remove the group from the chain in
remove_from_group (rather than here) to break refcounting cycles
(the chain always has a ref on the group). So assert that
group->chain==NULL.
(ref_group_by_count): Removed, it was commented out anyway.
(merge_chains): Use the remove_from_chain and add_to_chain
primitives to do the reparenting, instead of rolling our own
implementation.
(add_to_chain): The first non-disabled group in the chain's group
list will be the entry point for the chain. Because buffers can
accumulate in loop elements' peer bufpens, we preferentially
schedule loop groups before get groups to avoid unnecessary
execution of get-based groups when the bufpens are already full.
(gst_opt_scheduler_schedule_run_queue): Debug fixes.
(get_group_schedule_function): Ditto.
(loop_group_schedule_function): Ditto.
(gst_opt_scheduler_loop_wrapper): Ditto.
(gst_opt_scheduler_iterate): Ditto.

I understand the opt scheduler now, yippee!

(gst_pad_convert, gst_pad_query_default, gst_pad_query)
(gst_pad_get_formats_default, gst_pad_get_formats): Better
argument checks, and some doc fixes.

(gst_pad_custom_new_from_template): Um, does anyone
use these functions? Actually make a custom pad instead of a
normal one.
(gst_pad_try_set_caps): Transpose some checks.
(gst_pad_try_set_caps_nonfixed): Same, and use a macro to check if
the pad is in negotiation.
(gst_pad_try_relink_filtered): Use pad_link_prepare.

* gst/gstelement.c: Remove prototypes also defined in gstclock.h.

* gst/gstelement.h:
* gst/gstclock.h: Un-deprecate the old clocking API, as discussed
on the list.

Original commit message from CVS:
2004-02-20  Andy Wingo  <wingo@pobox.com>

* gst/gstbin.c:
* gst/gstbuffer.c:
* gst/gstplugin.c:
* gst/registries/gstxmlregistry.c:
* gst/schedulers/gstoptimalscheduler.c: Debugging tweaks.

* gst/gstelement.c (gst_element_set_scheduler): Debugging fixes.
(gst_element_add_pad): DEBUG->INFO, some fixes.
(gst_element_get_compatible_pad_template): Just see if the
templates' caps intersect, not if one is a strict subset of the
other. This conforms more to what gst_pad_link_intersect() does.
(gst_element_class_add_pad_template): Don't memcpy the pad
template, just ref it.
(gst_element_get_compatible_pad_filtered): Clean up debug messages

* gst/gstpad.c (gst_pad_can_link_filtered): Debug a true result.
(gst_pad_link_filtered): Debug changes.
(gst_pad_link_prepare): New function, consolidated from
can_link_filtered and link_filtered.

* gst/parse/grammar.y (gst_parse_perform_link): Made INFO output
look more like that of the functions in gstelement.c

* gst/gstinfo.c (gst_debug_print_object): Put a space before the
object, and return the empty string if object is NULL.

* gst/parse/parse.l: Remove trailing newlines when calling PRINT.
* gst/parse/grammar.y (YYFPRINTF): Log bison debugging info via
LOG, not DEBUG. We still get flex info on debug.

* gst/registries/gstxmlregistry.c (gst_xml_registry_load): Make
debug string more verbose.
(plugin_times_older_than): DEBUG->LOG.

(gst_clock_set_speed), (gst_clock_set_active),
(gst_clock_is_active), (gst_clock_reset),
(gst_clock_handle_discont):
* gst/gstclock.h:
deprecate old interface and disable functions that aren't in use
anymore.
* gst/gstelement.h:
* gst/gstelement.c: (gst_element_get_time), (gst_element_wait),
(gst_element_set_time), (gst_element_adjust_time):
add concept of "element time" and functions to get/set this time.
* gst/gstelement.c: (gst_element_change_state):
update element time correctly.
* gst/gstelement.c: (gst_element_get_compatible_pad_filtered):
This is a debug message, not a g_critical.
* gst/gstpad.c: (gst_pad_event_default):
handle discontinuous events right with element time.
* gst/gstscheduler.c: (gst_scheduler_state_transition):
update to clocking fixes.
set clocks on elements in READY=>PAUSED. The old behaviour caused
a wrong element time on the first element that started playing.

* testsuite/clock/clock2.c: (gst_clock_debug), (main):
update to test new element time.
* gst/autoplug/gstspideridentity.c: (gst_spider_identity_getcaps):

- changing of all GST_DEBUG messages to reflect that change
- reorganization of subsystem disabling
- addition of gstconfig.h.in so we can track the disablings
- <gst/gst.h> does not include <unistd.h> and <config.h> anymore
- documentation updated for gstinfo stuff (build the docs yourself to know what changed)
- bugfixes for making of the docs (files from CVS are not deleted anymore
- testsuite for debugging changes in testsuite/debug
