Hello,
> this patch series aims to save memory allocations and some system calls
> related to PA's client/server protocol implementation
I've pushed the cleanup patches indicated below so that the more important
changes become more prominent in the list
I intend to push the first 16 patch ('tagstruct', 'packet', 'pstream') by
the end of the week
regards, p.
> Peter Meerwald (51):
> tagstruct: Distinguish pa_tagstruct_new() use cases
> tagstruct: Replace dynamic flag with type
> tagstruct: Get rid of pa_tagstruct_free_data()
> tagstruct: Add type _APPENDED
> tagstruct: Use flist to potentially save calls to malloc()/free()
> packet: Hide internals of pa_packet, introduce pa_packet_data()
> packet: Make pa_packet_new() create fixed-size packets
> packet: Introduce pa_packet_new_data() to copy data into a newly
> created packet
> packet: Use flist to save calls to malloc()/free()
> pstream: Unionize item_info
> pstream: Add pa_pstream_send_tagstruct()
> pstream: #define PA_PSTREAM_SHM_SIZE
> pstream: Duplicate assignment, write.data is always NULL
> pstream: Only reset memchunk if it has been used
> pstream: Split up do_read()
> pstream: Use small minibuffer to combine several read()s if possible
> iochannel: Fix channel enable
> queue: Add pa_queue_peek() function
> pstream: Add helper functions reset_descriptor(), shm_descriptor()
> pstream: Peek into next item on send queue to see if it can be put
> into minibuffer together with current item
> pstream: Don't call defer_enable() on SHMRELEASE
> once: Inline functions
> rtpoll: Fix condition for DEBUG_TIMING output
pushed
> rtpoll: Drop extra wait_op argument to pa_rtpoll_run()
pushed
> mainloop: Clear wakeup pipe only when necessary
> flist: Don't use atomic operations to manipulate ptr, next
> flist: Don't make flist volatile
> rtpoll: Annotate branches with LIKELY
> mainloop: Annotate branches with LIKELY
> alsa: Make rtpoll_run() runtime measurement compile-time code, default
> off
> alsa: Annotate branches in ALSA sink/source thread_func() with LIKELY
> resampler: Drop pointless remix variable
pushed
> build-sys: Add --disable-statistics
> sample: Make pa_sample_size_table public
> sample: Make pa_channels_valid() inlineable
> sample-util: Add inlineable functions
> core: Make use of use inlineable macros
> resampler: Precompute maximum block size in frames
> mix: Make use of pa_cvolume_is_norm/muted() macros
pushed
> mix: Avoid redundant cvolume checks
> mix: pa_mix() is always called with more than one steam
pushed
> mix: Length over all chunk has already been computed by the caller
pushed
> core: Add volume-util.h
> core: Make use of volume macros
> iochannel: Remove unnecessary zero-initialization
pushed
> asyncmsgq: Drop weird assert
pushed
> protocol-native: Make sink_input_pop_cb() return entire chunk
> alsa-sink: Assume left_to_play can be computed, save one call to
> snd_pcm_avail()
> alsa: Refactor computation of sleep usec
> alsa: Precompute max_frames
pushed, adapted to David's comments
