52e3628... Yes, yet another evil all-in-one commit of intervowen changes. I suck. * Drop "state" directory, fold that into "runtime directory" * No longer automatically rewind when a new stream connects * Rework sound file stream, to cause a rewind on initialisation, shorten _pop() code a bit * Fix reference counting of pa_socket_server in the protocol implementations * Rework daemon initialization code to be compatible with non-SUID-root setups where RLIMIT_RTPRIO is non-zero * Print warning if RT/HP is enabled in the config, but due to missing caps, rlimits, policy we cannot enable it. * Fix potential memory leak in pa_open_config_file() * Add pa_find_config_file() which works much like pa_open_config_file() but doesn't actually open the config file in question. Just searches for it. * Add portable pa_is_path_absolute() * Add pa_close_all() and use it on daemon startup to close leaking file descriptors (inspired from what I did for libdaemon) * Add pa_unblock_sigs() and use it on daemon startup to unblock all signals (inspired from libdaemon, too) * Add pa_reset_sigs() and use it on daemon startup to reset all signal handlers (inspired from libdaemon as well) * Implement pa_set_env() * Define RLIMIT_RTTIME and friends if not defined by glibc * Add pa_strempty() * rename state testing macros to include _IS_, to make clearer that they are no states, but testing macros * Implement pa_source_output_set_requested_latency_within_thread() to be able to forward latency info to sources from within the IO thread * Similar for sink inputs * generelize since_underrun counter in sink inputs to "playing_for" and "underrun_for". Use only this for ignore potential rewind requests over underruns * Add new native protocol message PLAYBACK_STREAM_MESSAGE_STARTED for notification about the end of an underrun * Port native protocol to use underrun_for/playing_for which is maintained by the sink input anyway * Pass underrun_for/playing_for in timing info to client * Drop pa_sink_skip() since it breaks underrun detection code * Move PID file and unix sockets to the runtime dir (i.e. ~/.pulse). This fixes a potention DoS attack from other users stealing dirs in /tmp from us so that we cannot take them anymore) * Allow setting of more resource limits from the config file. Set RTTIME by default * Streamline daemon startup code * Rework algorithm to find default configuration files * If run in system mode use "system.pa" instead of "default.pa" as default script file * Change ladspa sink to use pa_clamp_samples() for clamping samples * Teach module-null-sink how to deal with rewinding * Try to support ALSA devices with no implicit channel map. Synthesize one by padding with PA_CHANNEL_POSITION_AUX channels. This is not tested since I lack hardware with these problems. * Make use of time smoother in the client libraries. * Add new pa_stream_is_corked() and pa_stream_set_started_callback() functions to public API * Since our native socket moved, add some code for finding sockets created by old versions of PA. This should ease upgrades
f94fae3... move unlinking code to operation_unlink()

b70edf7... port pa_sample_clamp() to liboil
9dd8f6c... add new function pa_sample_clamp()

f49df7a... * Increase history set to 64 to simplify reduction of indexes * Decrease memory consumption a bit by using bitfields for some bools * Rework reduction code * Drop an unnessacary counter * Before adding a new entry to the history, try to figure out if we already have an existing entry with the same x value and replace that. This fixes a division by zero * Fix up input x for all functions, according to the time offset
563f4b6... make check for $DISPLAY=="" more readable, pa_bool_tization

067a68a... fix build for auxiliary modules
c8fc223... add stripnul to build
76031df... Big pile of interdependant changes: * Fix a deadlock when an asyncq overflows and an RT thread needed to wait until space became available again while the main thread was waiting for a operation to complete and thus didn't free any new items. Now, if the asyncq overflows, queue those items temporarily, and return immediately. Then, when the queue becomes writable again, flush it. * Modify pa_thread_mq_init() to also set up pa_rtpoll events properly for the MQ * Some more pa_bool_t'ization * Unify more common code between alsa-sink and alsa-source * The upper limit for the tsched watermark is max_use minus one frame * make module-alsa-source work * make the alsa modules use pa_alsa_build_pollfd() now * fix detection of dB scale for alsa-source

ed0af46... unify code that fixes up buffering metrics
af03dd4... drop a misplaced newline
3c8e83f... do not fix automatic buffer attrs anymore, the new protocol version doesn't need this anymore and it creates more problems than it solves. Also drop the initial timing info query. Correct programs shouldn't depend on it anyway
5e6aacd... * don't increase tsched_watermark on underrun without limits * fix the watermark when we change the latency * fix latency measurement * move rewinding code into its own function * make use of new function pa_alsa_recover_from_poll() were applicable

cef6563... Assorted minor Windows compatibility fixes for recent code updates.
ce74146... Add stubs when RT signals aren't available.
8dcc1fa... Adapt rtpoll and friends to Windows by replacing timespec with timeval and add a fallback when clock_gettime() isn't available.
ef8812e... Replace all references to sys/poll.h with poll.h as that's what POSIX defines.
7c1768d... update native protocol to make use of pa_memblockq_pop_missing
2e780e8... Move request size handling into pa_memblockq, function pa_memblockq_pop_missing()
d6a2203... Fix race condition between IO thread creation and pa_sink_put(). Move activation of rtpoll fds when we change the state INIT->IDLE.
9d34a1e... fix trivial typo
abd692e... fix silence initializer for alaw and ulaw
dbcd086... Fixed PA_GCC_CONST definition.
bdf9746... Update module-solaris to new structure.
67b899a... treat timer_enabled like a real, grown-up boolean variable
33f2f49... rework module-combine once again. We now run the data generation always in a seperate thread. This should help use to avoid all the awful race conditions we had in previously
229afb5... Move the poll() call outside the #ifdef checking for ppoll, since we want the poll in all cases. Prior to this change the check for negative return values of poll/ppoll was never actually executed when ppoll() was available
f8c1786... use the full range of RTSIGS for our stuff
3cdff5f... Allocate rtsigs from back to front, to avoid clashes with other libraries makeing use of rtsigs
df33b4c... only do IO if we are RUNNING or IDLE, but not when we are in INIT
6d8aea7... Incorrectly used str2sig() instead of sig2str().

f0f9df9... * add new state changed hook for streams * update sink->n_corked properly when moving streams
ac86fa1... fix IDLE vs. RUNNING state handling of sinks/sources when changing cork status for streams
3c75d35... rework zeroconf service publishing, to use synchronous hooks instead of asynchronous subscription events. Don't push autoload entries anymore.
e37fa01... add hooks for name/description changes of sinks/source and streams
ef020c6... fix stream corking: ignore pa_sink_input() when we are in corked state
55651ec... don't count streams using the monitor source in pa_sink_used_by(), because this would disallow suspending a sink ehn an rtp stream is connected
ba322a4... drop the PA_SOURCE_CAN_SUSPEND and PA_SINK_CAN_SUSPEND flags, since they were a bad idea in the first place. All sinks/sources are now *required* to handle suspending in one way or another. Luckily all current sink/source implementations handle it fine anyway.
77ed60c... instead of using the mixer ioctl()s on the dsp fd, open a seperate fd for the mixer. This allows us the keep the mixer fd open while closing the dsp device while suspending.
fc00eaf... use O_NOFOLLOW when creating lock files, too
2860685... use O_NOFOLLOW when creating PID file, to avoid symlink vulnerability
de079ac... Added an assertion for the case when the sink programmer hasn't installed the thread_mq properly.

78a9ad3... - rework volume adjustment code to not require fp - don't hit an assert when we cannot do a volume adjustment, instead, print a warning and go on
d7a0876... fix selection of working format
9db4267... make use of byte swap builtins of gcc if they are available
f26de80... add test program for the resampler
c34a263... allow _unlink() functions to be called as many times as people want, even before _put() was called
1fc168b... clamp sample data to -1 .. 1, before passing it to the plugin; if a control port data specification is left empty, initialize with the default value of the plugin
29d25ec... add CLAMP macro
e205bb2... don't segfault when the master changes
3b2835d... properly detach/attach when moving sink inputs

75647bc... render new data always in the master sink's thread, fixing missing locking
a8a9ee4... make sure we initialize thread private data before we move our ghost sink to the rt thread, not after
42b71ff... fix trivial typo
d716e3c... fix check for lrintf, make resample2.c again identical to upstream ffmpeg
75f799a... make O_CLOEXEC, O_NONBLOCK and socket low latency fd ops more uniform: always return void, name them similarly, only pass a single fd
0fcad97... copy free_cb into a temporary variable first, to avoid compiler warning
ac66b6a... fall back to plughw:, if hw: doesn't work, in the alsa source, too
781cf49... properly release memblock always abd as soon as possible
1fd9afd... make use of pa_bool_t on a few places where applicable; really start work_cb
b3093d8... lower SO_PRIORITY priority to 6, since this is the best we get without being root
ef8df41... make rtp send socket low delay
f44ddd1... add new pa_socket_udp_low_delay() API
6b2fd23... add two missing header file inclusions
eb23601... bug fixes for module-rtp-recv
8fdf054... make sure we don't call pa_source_post() for a monitor source after it was unlinked
ca71764... If PTHREAD_PRIO_INHERIT mutexes are not available fall back to normal mutexes
a558e93... port module-rtp-send.c to lock-free core
08d4b23... actually close the alsa device before we try to reopen it as plughw
4ed41f3... strtof() is a rather recent addition to C. Fall back to strtod() if it isn't available.
aff22cf... NSIG seems to be more common than _NSIG.
03d9863... Emulate lrintf with simple truncation if it isn't available.
31dfb31... Make sure the header file is only included on linux (as this is a linux-only feature).
df1d347... NSIG is not defined by neither C99 nor POSIX so we can't rely on it.
4cde507... add LADSPA sink than can be piggy-backed ontop of another sink
7b4f981... print a message when we fall back on plughw
8ff7d56... add a locale-independant pa_atof() implementation
4cdf2ce... hide sig2str-test
1ae473b... fall back to plughw: if hw: doesn't work
26a1ae7... Rename pa_strsignal() to pa_sig2str(), since we return the symbolical signal name, not a human readable string. This follows the Solaris API of sig2str() a bit. Also, add all remaining signals to the list of signal names.
d3b8985... drop a couple of WARNING prefixes in log messages, since we have pa_log_warn anyway for marking warnings especially
19eb7eb... once.c is no longer POSIX specific. Since it is now considerably more advanced than it used to be, use it on windows, too
7f9fea7... on Linu disable lazy binding altogether
a1526f1... add missing initialization
061e806... Add a special ltdl .so loader that avoids lazy frelocations during runtime
2741685... use priority inheritance on mutexes where applicable
61b90a0... add proper boolean type pa_bool_t
116ddaa... use gcc const and pure function attributes wherever applicable
35483ee... add a new module module-remap-sink which can be used to remap the channel maps of an already existant sink. one use case is to create a virtual sink that redirects stereo data to the rear speakers of a surround card.
1d1eda6... add a "length" argument to the seek functions, as an optimization to request a certain block size if any data needs to be generated. this is merely a hint.
5df7a85... split memblocks into multiples of the mempool tile size
ac1ee4e... add new API pa_mempool_block_size_max() to query the maximum tile size
fce8507... * add a new resampler "copy" which is does not change sample rates but copies data unmodified from input to output. * add a new API pa_resampler_max_block_size() which can be used to determine the maximum input buffer size for the resampler so that the bounce buffers don't grow larger then the mempool tile size
d079b48... properly define MAX/MIN macros

298d239... trivial typo
8389264... count corked streams per sink/source and make pa_sink_used_by() return only the number of streams that are not corked. Introduce pa_sink_linked_by() returning the number of streams connected at all. This will allow suspending of sinks/sources when all streams connected to a sink are corked.
5ae4eed... Move attaching/detaching from a pa_rtpoll into pa_sink proper, remove it from module-combine
3396b65... simplify rt loops a bit by moving more code into pa_rtpoll. It is now possible to attach "work" functions to a pa_rtpoll_item, which will be called in each loop iteration. This allows us to hide the message processing in the RT loops and to drop the seperate sink_input->process hooks. Basically, only the driver-specific code remains in the RT loops.
f0b9dce... explicitly destory TLS data before destroying TLS
bf274cb... add two new macros PA_ONCE_BEGIN and PA_ONCE_END which allow usage of pa_once without declaring a function to be called

03f311a... reindent, and s/assert/pa_assert/g
4137865... change pa_modargs_get_channel_map() to take an extra argument for specifying the name of the modargs attribute to parse
d9c4c95... add new pa_pipe_close() API to close two fds at the same time
7f92542... consolidate close() calls to pa_close(), and make sure on every occasion that we handle failures of close() sensibly
54506ab... on systems where we know that POSIX shm is mapped to /dev/shm, add the ability to cleanup stale SHM segments. (Right now only Linux)
d5bedbc... remaining s/assert/pa_assert/ and refcnt.h modernizations
2988c3d... Rework core-error.c on top of PA_STATIC_TLS_DECLARE, the windows specific parts need to be moved to thread-win32.c

597a1c4... port client libs to refcnt.h
55d9fcb... add globally defined PA_PATH_SEP macro, replacing private per-file macros
6ac66e4... add missing config.h includes
e2e2ce7... Instead of including config.h from header files, check whether PACKAGE is defined and if not, fail (thus using PACKAGE as a check for inclusion of config.h)
848a4d7... more s/assert/pa_assert/ modernizations
9b0ab39... unify static TLS support, make use of gcc __thread attribute if available
3d122d0... s/assert/pa_assert/ modernizations
de21b54... add new API pa_threaded_mainloop_in_thread(), update test case for it
a6f8b81... simple modernizations: s/assert/pa_assert

d5caa02... minor cleanup
a77158e... make the memchunk writeable before silencing it
841fcb4... beef up comment
98f9bd6... make sure that the device volume is properly read before we call pa_sink_put() and thus make the pa_sink available
69ece66... add pulseaudio logo with text
44e514c... update todo file a little
6c1682c... hide a couple of files
27c3bd4... document that the native amd64 atomic ops implementation is incomplete
06db921... don't call pa_source_process_msg() for PA_SOURCE_MESSAGE_GET_LATENCY, since it makes querying the latency always fail
d9b3c0e... posix_madvise and posix_fadvise aren't present on all systems.
9630e8d... Remove mkdir_p again...
028632f... TIOCINQ isn't present on all systems.
e176601... Monotonic clock is optional so treat is as such.

3b2cf1a... update default config: - check for existance of modules before loading them - disable all event sounds except hotplug by default
b1fd53b... explicitly test for the availability of dbus_watch_get_unix_fd() before using it. The previous version-based check didn't work anyway since the constants checked for weren't set.

ba06340... Add some required headers.
357ab88... Make sure socklen_t is defined.

7192238... Old kernel headers didn't define the input_id structure. Therefore we cannot rely on it.
c5bee95... Fix correct type.
4deeaef... Don't include sys/socket.h in the header when we do not need to.

commit 1f11ee3c8b392a68685875478637ce875de85da2
Author: Pierre Ossman <ossman at cendio.se>
Date:   Thu Jan 5 13:07:00 2006 +0000

    Big cleanup of the build structure.
    
     * configure.ac is divided into distinct sections for programs, headers,
       optional components, etc.
    
     * polyp/Makefile.am is organised into several sections instead of a big mess.
    
     * Conditionals are only for adding things to the primaries, not around their
       build rules.
    
     * polypcore has been brought up to date in preparation for the Windows port.
       It is not possible to use the current tricks there.

    Port to Windows. This is mostly glue layers for the poor POSIX support
    on Windows. A few notes
    
     * Only sockets behave somewhat like file descriptors in UNIX.
    
     * There are no fixed paths. Closes thing is environment variables that point
       to system directories. We also figure out where the binary/dll is
       located and use that as configuration directory.

    Static libs bork the creation of dlls and AC_CHECK_LIB isn't very bright,
    so we have to do a test first to see if getopt_long() is included in the

commit 0defdfb5607889c35fdefff4af31eb8b0ae0cbcf
Author: Lennart Poettering <lennart at poettering.net>
Date:   Tue Jul 31 22:44:53 2007 +0000

    A lot of updates, all necessary to get the native protocol ported:
    
    * add an int64_t argument to pa_asyncmsgq because it is very difficult to pass 64 values otherwise
    * simplify subclassing in pa_object
    * s/drop/unlink/ at some places
    * port the native protocol to the lock-free core (not tested, compiles fine)
    * move synchronisation of playback streams into pa_sink_input
    * add "start_corked" field to pa_sink_input_new_data
    * allow casting of NULL values in pa_object

    by default, store esd socket in /tmp/.esd-`id -u`/socket, instead of /tmp/.esd/socket, to allow multiple simultaneous esd instances. this is only compatible with a patched esd, which however ubuntu and fedora ship now. other distros need to patch their esd as well, or may pass socket=/tmp/.esd/socket to module-protocol-esound-unix

    * make pa__done() implementations optional
    * a couple of modernizations
    * wrap lt_dlsym() at a single place
    * allow passing of an "api" argument to the HAL module, to choose whether OSS devices or ALSA devices should be picked up
    * optimize fd closing a little on linux in the forked gconf helper
    * save a little memory in the xsmp module

+                  GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+^L
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it
+becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+^L
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control
+compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+^L
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+^L
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+^L
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+^L
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply, and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License
+may add an explicit geographical distribution limitation excluding those
+countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+^L
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+^L
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms
+of the ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.
+It is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should
+have at least the "copyright" line and a pointer to where the full
+notice is found.
+
+
+    <one line to give the library's name and a brief idea of what it
+does.>
+    Copyright (C) <year>  <name of author>
+

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.

+ * 1) It uses timer_create() and POSIX real time signals to guarantee
+ * optimal high-resolution timing. Starting with Linux 2.6.21 hrtimers
+ * are available, and since right now only nanosleep() and the POSIX
+ * clock and timer interfaces have been ported to hrtimers (and not
+ * ppoll/pselect!) we have to combine ppoll() with timer_create(). The
+ * fact that POSIX timers and POSIX rt signals are used internally is
+ * completely hidden.
+ *
+ * 2) It allows raw access to the pollfd data to users
+ *
+ * 3) It allows arbitrary functions to be run before entering the
+ * actual poll() and after it.

+   The design goals of this code are:
+      - Very fast algorithm
+      - SIMD-friendly algorithm
+      - Low memory requirement
+      - Good *perceptual* quality (and not best SNR)
+
+   The code is working, but it's in a very early stage, so it may have
+   artifacts, noise or subliminal messages from satan. Also, the API 
+   isn't stable and I can actually promise that I *will* change the API
+   some time in the future.
+
+TODO list:
+      - Variable calculation resolution depending on quality setting
+         - Single vs double in float mode
+         - 16-bit vs 32-bit (sinc only) in fixed-point mode
+      - Make sure the filter update works even when changing params 
+             after only a few samples procesed

commit 4d623f0d4442148f20f2ffdc85cf95e54ef83721
Author: Lennart Poettering <lennart at poettering.net>
Date:   Thu Aug 30 22:57:53 2007 +0000

    Lots of assorted minor cleanups and fixes:
    * s/disconnect/unlink/ at many places where it makes sense
    * make "start_corked" a normal pa_sink_input/pa_source_output flag instead of a seperate boolean variable
    * add generic process() function to pa_sink_input/pa_source_output vtable that can be used by streams to do some arbitrary processing in each rt loop iteration even the sink/source is suspended
    * add detach()/attach() functions to pa_sink_input/pa_source_output vtable that are called when ever the rtpoll object of the event thread changes
    * add suspend() functions to pa_sink_input/pa_source_output vtable which are called whenever the sink/source they are attached to suspends/resumes
    * add PA_SINK_INIT/PA_SOURCE_INIT/PA_SINK_INPUT_INIT/PA_SINK_OUTPUT_INIT states to state machines which is active between _new() and _put()
    * seperate _put() from _new() for pa_sink/pa_source
    * add PA_SOURCE_OUTPUT_DONT_MOVE/PA_SINK_INPUT_DONT_MOVE flags
    * make the pa_rtpoll object a property of pa_sink/pa_source to allow streams attached to them make use of it
    * fix skipping over move_silence
    * update module-pipe-source to make use of pa_rtpoll
    * add pa_sink_skip() as optimization in cases where the actualy data returned by pa_sink_render() doesn't matter

commit e2e2ce79e2697ecbd36e2cf00249dc8c59af232d
Author: Lennart Poettering <lennart at poettering.net>
Date:   Tue Sep 11 00:30:53 2007 +0000

    Instead of including config.h from header files, check whether PACKAGE is defined and if not, fail (thus using PACKAGE as a check for inclusion of config.h)

commit 391d09cd6e8d47ad8255736be5cb512b04843ed1
Author: Lennart Poettering <lennart at poettering.net>
Date:   Tue Sep 11 13:15:39 2007 +0000

    add 'wait' parameter to pa_rtpoll_run(), if zero pa_rtpoll_runn will only update the struct pollfd but not wait for an event

commit 54506ab44a9ac61e79b3a5c632db56bde41beded
Author: Lennart Poettering <lennart at poettering.net>
Date:   Tue Sep 11 23:12:24 2007 +0000

    on systems where we know that POSIX shm is mapped to /dev/shm, add the ability to cleanup stale SHM segments. (Right now only Linux)

commit 7f92542420ef6085b6f090954052266cc70af8a1
Author: Lennart Poettering <lennart at poettering.net>
Date:   Wed Sep 12 00:04:21 2007 +0000

    simplify rt loops a bit by moving more code into pa_rtpoll. It is now possible to attach "work" functions to a pa_rtpoll_item, which will be called in each loop iteration. This allows us to hide the message processing in the RT loops and to drop the seperate sink_input->process hooks. Basically, only the driver-specific code remains in the RT loops.

commit 8389264d6560d32b3912c60474497742807efbde
Author: Lennart Poettering <lennart at poettering.net>
Date:   Sat Sep 15 14:21:05 2007 +0000

    count corked streams per sink/source and make pa_sink_used_by() return only the number of streams that are not corked. Introduce pa_sink_linked_by() returning the number of streams connected at all. This will allow suspending of sinks/sources when all streams connected to a sink are corked.

    * add a new resampler "copy" which is does not change sample rates but copies data unmodified from input to output.
    * add a new API pa_resampler_max_block_size() which can be used to determine the maximum input buffer size for the resampler so that the bounce buffers don't grow larger then the mempool tile size

commit 35483eeab7d08bc3e7ab2cd7a91e3d7453dca605
Author: Lennart Poettering <lennart at poettering.net>
Date:   Sun Sep 16 22:03:19 2007 +0000

    add a new module module-remap-sink which can be used to remap the channel maps of an already existant sink. one use case is to create a virtual sink that redirects stereo data to the rear speakers of a surround card.

commit 26a1ae7bbb5f95aa9117cac1f693c79289c8e124
Author: Lennart Poettering <lennart at poettering.net>
Date:   Mon Sep 17 15:26:18 2007 +0000

    Rename pa_strsignal() to pa_sig2str(), since we return the symbolical signal name, not a human readable string. This follows the Solaris API of sig2str() a bit. Also, add all remaining signals to the list of signal names.

+
+/* Overview: 
+
+   There is a large number of synthesis packages in use or development
+   on the Linux platform at this time. This API (`The Linux Audio
+   Developer's Simple Plugin API') attempts to give programmers the
+   ability to write simple `plugin' audio processors in C/C++ and link
+   them dynamically (`plug') into a range of these packages (`hosts').
+   It should be possible for any host and any plugin to communicate
+   completely through this interface.
+
+   This API is deliberately short and simple. To achieve compatibility
+   with a range of promising Linux sound synthesis packages it
+   attempts to find the `greatest common divisor' in their logical
+   behaviour. Having said this, certain limiting decisions are
+   implicit, notably the use of a fixed type (LADSPA_Data) for all
+   data transfer and absence of a parameterised `initialisation'
+   phase. See below for the LADSPA_Data typedef.
+
+   Plugins are expected to distinguish between control and audio
+   data. Plugins have `ports' that are inputs or outputs for audio or
+   control data and each plugin is `run' for a `block' corresponding
+   to a short time interval measured in samples. Audio data is
+   communicated using arrays of LADSPA_Data, allowing a block of audio
+   to be processed by the plugin in a single pass. Control data is
+   communicated using single LADSPA_Data values. Control data has a
+   single value at the start of a call to the `run()' or `run_adding()'
+   function, and may be considered to remain this value for its
+   duration. The plugin may assume that all its input and output ports
+   have been connected to the relevant data location (see the
+   `connect_port()' function below) before it is asked to run.
+
+   Plugins will reside in shared object files suitable for dynamic
+   linking by dlopen() and family. The file will provide a number of
+   `plugin types' that can be used to instantiate actual plugins
+   (sometimes known as `plugin instances') that can be connected
+   together to perform tasks.
+
+   This API contains very limited error-handling. */

+   is used to communicate audio samples and control values. It is
+   assumed that the plugin will work sensibly given any numeric input
+   value although it may have a preferred range (see hints below). 
+
+   For audio it is generally assumed that 1.0f is the `0dB' reference
+   amplitude and is a `normal' signal level. */

+   management within its run() or run_adding() functions. All new
+   memory used in run() must be managed via the stack. These
+   restrictions only apply to the run() function.
+
+   (2) The plugin will not attempt to make use of any library
+   functions with the exceptions of functions in the ANSI standard C
+   and C maths libraries, which the host is expected to provide.
+
+   (3) The plugin will not access files, devices, pipes, sockets, IPC
+   or any other mechanism that might result in process or thread
+   blocking.
+      
+   (4) The plugin will take an amount of time to execute a run() or
+   run_adding() call approximately of form (A+B*SampleCount) where A
+   and B depend on the machine and host in use. This amount of time
+   may not depend on input signals or plugin state. The host is left

    - rework volume adjustment code to not require fp
    - don't hit an assert when we cannot do a volume adjustment, instead, print a warning and go on

commit ba322a49e1754eba11495da9a10e3e0dbbe89244
Author: Lennart Poettering <lennart at poettering.net>
Date:   Mon Sep 24 16:10:43 2007 +0000

    drop the PA_SOURCE_CAN_SUSPEND and PA_SINK_CAN_SUSPEND flags, since they were a bad idea in the first place. All sinks/sources are now *required* to handle suspending in one way or another. Luckily all current sink/source implementations handle it fine anyway.

commit 3c75d35dd004a55753934ed328d7e037cbf8c596
Author: Lennart Poettering <lennart at poettering.net>
Date:   Mon Sep 24 21:49:02 2007 +0000

    rework zeroconf service publishing, to use synchronous hooks instead of asynchronous subscription events. Don't push autoload entries anymore.
    
    
    git-svn-id: file:///home/lennart/svn/public/pulseaudio/branches/lennart@1898 fefdeb5f-60dc-0310-8127-8f9354f1896f

commit 229afb5e2dca2ea4cf8e5f48268cd9c419ea6f4b
Author: Lennart Poettering <lennart at poettering.net>
Date:   Fri Sep 28 13:00:35 2007 +0000

    Move the poll() call outside the #ifdef checking for ppoll, since we want the poll in all cases. Prior to this change the check for negative return values of poll/ppoll was never actually executed when ppoll() was available

commit 8dcc1fa6161c2a507d008a50a6d7f5170ce54a14
Author: Pierre Ossman <ossman at cendio.se>
Date:   Wed Oct 3 14:43:56 2007 +0000

    Adapt rtpoll and friends to Windows by replacing timespec with timeval and
    add a fallback when clock_gettime() isn't available.

+/* General overview:
+ *
+ * Because JACK has a very unflexible event loop management, which
+ * doesn't allow us to add our own event sources to the event thread
+ * we cannot use the JACK real-time thread for dispatching our PA
+ * work. Instead, we run an additional RT thread which does most of
+ * the PA handling, and have the JACK RT thread request data from it
+ * via pa_asyncmsgq. The cost is an additional context switch which
+ * should hopefully not be that expensive if RT scheduling is
+ * enabled. A better fix would only be possible with additional event
+ * source support in JACK.

Date:   Tue Oct 23 22:55:56 2007 +0000

    add better time interpolator: use linear regression to determine gradient from
    measurements, predict a short distance ahead, and smoothen estimation function
    with 3rd degree spline interpolation.

+ * clocks to a local one. Evens out noise, adjusts to clock skew and
+ * allows cheap estimations of the remote time while clock updates may
+ * be seldom and recieved in non-equidistant intervals.
+ *
+ * Basically, we estimate the gradient of received clock samples in a
+ * certain history window (of size 'history_time') with linear
+ * regression. With that info we estimate the remote time in
+ * 'adjust_time' ahead and smoothen our current estimation function
+ * towards that point with a 3rd order polynomial interpolation with
+ * fitting derivatives. (more or less a b-spline)
+ *
+ * The larger 'history_time' is chosen the better we will surpress
+ * noise -- but we'll adjust to clock skew slower..
+ *
+ * The larger 'adjust_time' is chosen the smoother our estimation
+ * function will be -- but we'll adjust to clock skew slower, too.
+ *
+ * If 'monotonic' is TRUE the resulting estimation function is
+ * guaranteed to be monotonic.

-         - 16-bit vs 32-bit (sinc only) in fixed-point mode
-      - Make sure the filter update works even when changing params
-             after only a few samples procesed
+   Warning: This resampler is relatively new. Although I think I got rid of
+   all the major bugs and I don't expect the API to change anymore, there
+   may be something I've missed. So use with caution.
+
+   This algorithm is based on this original resampling algorithm:
+   Smith, Julius O. Digital Audio Resampling Home Page
+   Center for Computer Research in Music and Acoustics (CCRMA),
+   Stanford University, 2007.
+   Web published at http://www-ccrma.stanford.edu/~jos/resample/.
+
+   There is one main difference, though. This resampler uses cubic
+   interpolation instead of linear interpolation in the above paper. This
+   makes the table much smaller and makes it possible to compute that table
+   on a per-stream basis. In turn, being able to tweak the table for each
+   stream makes it possible to both reduce complexity on simple ratios
+   (e.g. 2/3), and get rid of the rounding operations in the inner loop.
+   The latter both reduces CPU time and makes the algorithm more SIMD-friendly.

commit cdfcf6654cb826682812e9d1096dcfbac77900eb
Author: Lennart Poettering <lennart at poettering.net>
Date:   Thu Apr 3 13:40:55 2008 +0000

    - deprecate autoload stuff
    - allow setting of the requested latency of a sink input/source output before _put() is called
    - allow sinks/sources to have a "minimal" latency which applies to all requested latencies by sink inputs/source outputs
    - add new client library flags PA_STREAM_ADJUST_LATENCY, PA_STREAM_START_MUTED
    - allow client library to fill in 0 to buffer_attr fields
    - update module-alsa-source following module-alsa-sink
    - other cleanups and fixes

commit 07f5c1d8e433b5feb4f8b7a4307477e071234f1a
Author: Lennart Poettering <lennart at poettering.net>
Date:   Fri Apr 11 17:05:46 2008 +0000

    register sink/source name as first step when creating a new sink/source so that we can hand the valid name string to the hook functions; se tup props for monitor sources correctly; fix implicit flag setting logic

commit 62e7bc17c41c5542779a3c395a9d47d2bd306de2
Author: Lennart Poettering <lennart at poettering.net>
Date:   Sun Apr 20 20:16:55 2008 +0000

    Big pile of dependant changes:
    * Change pa_memblockq to carry silence memchunk instead of memblock and adapt all users
    * Add new call pa_sink_input_get_silence() to get the suitable silence block for a sink input
    * Implement monitoring sources properly by adding a delay queue to even out rewinds
    * Remove pa_{sink|source}_ping() becaused unnecessary these days and not used
    * Fix naming of various rewind related functions. Downstream is now _request_rewind(), upstream is _process_rewind()
    * Fix volume adjustments for a single stream in pa_sink_render()
    * Properly handle prebuf-style buffer underruns in pa_sink_input
    * Don't allow rewinding to more than the last underrun
    * Rework default buffering metrics selection for native protocol
    * New functions pa_memblockq_prebuf_active(), pa_memblockq_silence()
    * add option "mixer_reset=" to module-alsa-sink
    * Other cleanups

    - Change meaning of special values of latency request: 0 -> "minimal latency, please"; (pa_usec_t)-1 -> "don't care"
    - Remove "source" word from monitor source description
    - Increase default tsched watermark to 20ms again
    - For the first iteration after snd_pcm_start() halve the sleep time as workaround for USB devices with quick starts

commit 3c8e83fb3ebd4e1e6496e047cbf4c357550631b4
Author: Lennart Poettering <lennart at poettering.net>
Date:   Wed Apr 23 18:10:34 2008 +0000

    do not fix automatic buffer attrs anymore, the new protocol version doesn't need this anymore and it creates more problems than it solves. Also drop the initial timing info query. Correct programs shouldn't depend on it anyway

    Big pile of interdependant changes:
    * Fix a deadlock when an asyncq overflows and an RT thread needed to wait until space became available again while the main thread was waiting for a operation to complete and thus didn't free any new items. Now, if the asyncq overflows, queue those items temporarily, and return immediately. Then, when the queue becomes writable again, flush it.
    * Modify pa_thread_mq_init() to also set up pa_rtpoll events properly for the MQ
    * Some more pa_bool_t'ization
    * Unify more common code between alsa-sink and alsa-source
    * The upper limit for the tsched watermark is max_use minus one frame
    * make module-alsa-source work
    * make the alsa modules use pa_alsa_build_pollfd() now
    * fix detection of dB scale for alsa-source

commit 52e3628c3edd98ae3402605e7f44a0fc4545dd0a

Date:   Thu May 1 19:51:05 2008 +0000

    Yes, yet another evil all-in-one commit of intervowen changes. I suck.
    * Drop "state" directory, fold that into "runtime directory"
    * No longer automatically rewind when a new stream connects
    * Rework sound file stream, to cause a rewind on initialisation, shorten _pop() code a bit
    * Fix reference counting of pa_socket_server in the protocol implementations
    * Rework daemon initialization code to be compatible with non-SUID-root setups where RLIMIT_RTPRIO is non-zero
    * Print warning if RT/HP is enabled in the config, but due to missing caps, rlimits, policy we cannot enable it.
    * Fix potential memory leak in pa_open_config_file()
    * Add pa_find_config_file() which works much like pa_open_config_file() but doesn't actually open the config file in question. Just searches for it.
    * Add portable pa_is_path_absolute()
    * Add pa_close_all() and use it on daemon startup to close leaking file descriptors (inspired from what I did for libdaemon)
    * Add pa_unblock_sigs() and use it on daemon startup to unblock all signals (inspired from libdaemon, too)
    * Add pa_reset_sigs() and use it on daemon startup to reset all signal handlers (inspired from libdaemon as well)
    * Implement pa_set_env()
    * Define RLIMIT_RTTIME and friends if not defined by glibc
    * Add pa_strempty()
    * rename state testing macros to include _IS_, to make clearer that they are no states, but testing macros
    * Implement pa_source_output_set_requested_latency_within_thread() to be able to forward latency info to sources from within the IO thread
    * Similar for sink inputs
    * generelize since_underrun counter in sink inputs to "playing_for" and "underrun_for". Use only this for ignore potential rewind requests over underruns
    * Add new native protocol message PLAYBACK_STREAM_MESSAGE_STARTED for notification about the end of an underrun
    * Port native protocol to use underrun_for/playing_for which is maintained by the sink input anyway
    * Pass underrun_for/playing_for in timing info to client
    * Drop pa_sink_skip() since it breaks underrun detection code
    * Move PID file and unix sockets to the runtime dir (i.e. ~/.pulse). This fixes a potention DoS attack from other users stealing dirs in /tmp from us so that we cannot take them anymore)
    * Allow setting of more resource limits from the config file. Set RTTIME by default
    * Streamline daemon startup code
    * Rework algorithm to find default configuration files
    * If run in system mode use "system.pa" instead of "default.pa" as default script file
    * Change ladspa sink to use pa_clamp_samples() for clamping samples
    * Teach module-null-sink how to deal with rewinding
    * Try to support ALSA devices with no implicit channel map. Synthesize one by padding with PA_CHANNEL_POSITION_AUX channels. This is not tested since I lack hardware with these problems.
    * Make use of time smoother in the client libraries.
    * Add new pa_stream_is_corked() and pa_stream_set_started_callback() functions to public API
    * Since our native socket moved, add some code for finding sockets created by old versions of PA. This should ease upgrades

commit df92b23fa6e520127309c2f63e1f22c7d222e734
Author: Lennart Poettering <lennart at poettering.net>
Date:   Fri May 9 22:48:37 2008 +0000

    - Fix moving of sink inputs between sinks
    - Don't write more than a single buffer size in the ALSA driver at a time, to give the clients time to fill up the memblockq again
    - Add API for querying the requested latency of a sink input/source output
    - Drop get_letancy() from vtable of sinks/sources
