Subject: remove underrun condition in pa_sinks. Instead return silence in
 pa_sink_render() when necessary. This is required to guarantee that the time
 functions in connected sink inputs stays linear

From 0defdfb5607889c35fdefff4af31eb8b0ae0cbcf Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Tue, 31 Jul 2007 22:44:53 +0000
Subject: 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

Subject: 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

Subject: * drop redundant pa_core argument from module initialization
 functions * make pa__done() implementations optional * a couple of
 modernizations * wrap lt_dlsym() at a single place * allow passing of an

 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

From 50e014e7a9bc1742d5a9f37f7fa057a6a23a1d6c Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Sat, 11 Aug 2007 19:08:06 +0000
Subject: use single array for storing pa_core hook lists, add sink state
 changed hook, drop NO_HOOKS flags for sink inputs/source outputs, listen for
 resume events in module-suspend-on-idle.c

Subject: modernize pa_play_memblockq() and add a new function
 pa_memblockq_sink_input_new() which allows creation of memblockq streams
 without activating them immediately

+                       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>
+
+    This library is free software; you can redistribute it and/or

+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of

+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301  USA
+
+Also add information on how to contact you by electronic and paper
+mail.
+
+You should also get your employer (if you work as a programmer) or
+your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+

+# 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
+# configured tree to be moved without reconfiguration.

+\`configure' configures libltdl 1.2 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+			  [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+			  [PREFIX]
+
+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'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR           user executables [EPREFIX/bin]

+  --includedir=DIR       C header files [PREFIX/include]
+  --oldincludedir=DIR    C header files for non-gcc [/usr/include]

+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  CXXCPP      C++ preprocessor
+  F77         Fortran 77 compiler command
+  FFLAGS      Fortran 77 compiler flags
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+  -LLIBDIR          search LIBDIR for required installed libraries
+  -lNAME            OUTPUT-FILE requires the installed library libNAME
+  -module           build a library that can dlopened
+  -no-fast-install  disable the fast-install mode
+  -no-install       link a not-installable executable
+  -no-undefined     declare that a library does not refer to external symbols
+  -o OUTPUT-FILE    create OUTPUT-FILE from the specified objects
+  -objectlist FILE  Use a list of object files found in FILE to specify objects
+  -precious-files-regex REGEX
+                    don't remove output files matching REGEX
+  -release RELEASE  specify package release information
+  -rpath LIBDIR     the created library will eventually be installed in LIBDIR

+All other options (arguments beginning with \`-') are ignored.
+
+Every other argument is treated as a filename.  Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
+only library objects (\`.lo' files) may be specified, and \`-rpath' is
+required, except when creating a convenience library.
+
+If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created
+using \`ar' and \`ranlib', or on Windows using \`lib'.
+

+ *
+ * 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.
+ *
+ * Only a single interval timer is supported..*/

+      - Good *perceptual* quality (and not best SNR)

From: Lennart Poettering <lennart@poettering.net>
Date: Thu, 30 Aug 2007 22:57:53 +0000
Subject: 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

From 54506ab44a9ac61e79b3a5c632db56bde41beded Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Tue, 11 Sep 2007 23:12:24 +0000
Subject: 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)

From 7f92542420ef6085b6f090954052266cc70af8a1 Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Wed, 12 Sep 2007 00:04:21 +0000
Subject: consolidate close() calls to pa_close(), and make sure on every
 occasion that we handle failures of close() sensibly

Subject: 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.

From 8389264d6560d32b3912c60474497742807efbde Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Sat, 15 Sep 2007 14:21:05 +0000
Subject: 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.

 request a certain block size if any data needs to be generated. this is
 merely a hint.

From 35483eeab7d08bc3e7ab2cd7a91e3d7453dca605 Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Sun, 16 Sep 2007 22:03:19 +0000
Subject: 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.

Subject: drop a couple of WARNING prefixes in log messages, since we have
 pa_log_warn anyway for marking warnings especially

From 26a1ae7bbb5f95aa9117cac1f693c79289c8e124 Mon Sep 17 00:00:00 2001

Date: Mon, 17 Sep 2007 15:26:18 +0000
Subject: 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. */
+
+/*****************************************************************************/

+/* Fundamental data type passed in and out of plugin. This data type
+   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. */

+
+   (1) The plugin must not use malloc(), free() or other heap memory
+   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
+   the responsibility to perform timings to estimate upper bounds for
+   A and B. */

From 77ed60ce4cd02cb4b383ab4d6e9b51701fb03a07 Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Sun, 23 Sep 2007 21:03:24 +0000
Subject: 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.

From ba322a49e1754eba11495da9a10e3e0dbbe89244 Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Mon, 24 Sep 2007 16:10:43 +0000
Subject: 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.

From 33f2f497de3c1a99a05cc20172a7b03b38a084e1 Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Fri, 28 Sep 2007 13:02:28 +0000
Subject: 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

From: Lennart Poettering <lennart@poettering.net>
Date: Mon, 1 Oct 2007 16:39:04 +0000
Subject: Fix race condition between IO thread creation and pa_sink_put(). Move
 activation of rtpoll fds when we change the state INIT->IDLE.

+ * 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

+ * Implementation of a time smoothing algorithm to synchronize remote
+ * 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.

 crash on them anymore (the plugins correctly assume that every port is
 connected to a buffer, so we connect them to a dummy buffer that isn't used
 anywhere).
