Unless overriden during configure stage, autostart now defaults to
none.
This is safer approach for packagers wanting to provide both
jackdbus and jackd executables (via two distinct packages).

The updated build.yml will be made to work on any linux distro,
not only debian derivates. While currently Ubuntu is provided at
github, a runner verifying the build for upstream should run
"./waf --configure && ./waf" steps instead of the deleted ones, that
were running Ubuntu specific steps.
When 14 years ago --dbus configure option was added to wscript,
I was affraid that deployments of builds configured with defaults will
get broken, so I kept jackd daemon enabled by default.
Since then the mixed jackd+jackdbus deployments had happened -
a bunch of distro packagers ignored the upstream configure time
warning and the JACK2 project suggested packaging approach that
strongly discouraged such deployments.
Another issue that has proven problematic is the configuration of
autolaunching capabilities. For the sake of robust jackdbus
deployments, I'm also enabling dbus autolaunching. This will ensure
that jackdbus daemon will work as designed and expected to behave.
This commit is first of several that will remove the jackd code
from the source tree. Then, jackdbus will be buildabe from
dedicated repo+branch for jackdbus source code only, to be built
against jack2 (with jackdbus stuff removed), installed system-wide and
libjackserver accessible through pkg-config.
Reduce the base latencies for capture and playback by half a period,
and let the update method account for the additional playback latency
introduced by OSS buffer management.
This fits actual OSS latencies better, so the same settings for the
extra input-latency and output-latency parameters should apply to
different period lengths.
Beware that this change invalidates current input-latency and
output-latency values, they have to be measured again.
dbus/jack_control:
Remove unused imports for os and traceback.print_exc.
Fix indentation, whitespace and line length issues across the entire
file.
Simplify printing in `print_help()` by calling `print()` only once.
* jack_control: move to tools for a while
* jack_control: shell mode command
This command runs loop, which executes commands from stdin until EOF
(Ctrl+D in terminal). Command status is printed to stdout.
* jack_control: optimize some functions
* jack_control: unused function
* jack_control: more informative message about dbus typesig error
* jack_control: Fix shell mode I/O
* restore jack_control path
* Add flake8 configuration
.flake8:
Add flake8 configuration that limits the line length to 120 chars and
outputs to flake8.txt
* Add flake8.txt to gitignore
.gitignore:
Add flake8.txt (flake8 output file) to ignore.
* Syntax fixes and cleanup for top-level wscript
wscript:
Fix syntax of wscript according to pep8 (but do not break long lines).
Remove unused imports and move all module level imports to the top of
the file.
Fix broken build target of IIO driver (source argument to
`create_driver_obj()` supplied an uninitialized variable).
Break lines at 120 chars.
* Fix common/wscript syntax
common/wscript:
Fix syntax problems, unneeded imports and break lines at 120 chars.

compat/alloca/wscript:
Fix compat/alloca/wscript syntax
* Fix compat/wscript syntax
compat/wscript:
Fix compat/wscript syntax
* Fix dbus/wscript syntax
dbus/wscript:
Fix syntax and break lintes at 120 chars.
* Fix example-clients/wscript syntax
example-clients/wscript:
Fix syntax and remove commented code.
* Fix tests/wscript syntax
tests/wscript:
Fix syntax and commented code.
* Fix tools/wscript syntax
tools/wscript:
Fix tools/wscript syntax.
* Add github workflow for linting wscripts
.github/workflows/lint.yml:
Add github workflow for linting wscripts using findutils and flake8.
* Fix project version extraction in CI
.github/workflows/build.yml:
Adapt the project version extraction in CI to the syntax changes in
the top-level wscript.
* JackWeakAPI: fix DLL loading on Windows
LoadLibrary takes a LPCWSTR (UTF16). LoadLibraryA is needed to
work with ASCII C string literals.
* JackWeakAPI: call tryload_libjack if it hasn't been called already
On non-Windows tryload_libjack is loaded on startup with
__attribute__((constructor)) but with MSVC, Microsoft documentation
says to not load libraries in a DLL's initialization function:
https://docs.microsoft.com/en-us/windows/win32/dlls/dynamic-link-library-best-practices
* JackWeakAPI: add debugging message for Windows
The code did a pointer-sized heap allocation instead of the actual size
of a semaphore struct sem_t. This could result in heap memory corruption
when handling the semaphore.
Found by llvm scan-build.
When using as sync opbject the given 'value' is meant to
already 'unblock' for that amount of Wait calls.

This fixes path relocation in mingw environment. Without this,
libdir and includedir are not shown in pkgconfig output. e.g.
* Without predefined variables:
- pkgconf -cflags jack: No output
- pkgconf -libs jack: -ljack64
* With predefined variables:
- pkgconf -cflags jack: -IC:/msys64/mingw64/include
- pkgconf -libs jack: -LC:/msys64/mingw64/lib -ljack64
Also official documentation suggests to use variables

Unbreak the build with Clang on architectures where JACK uses non-packed
data structures, like arm64 or powerpc. The alignment errors are exposed
there because:
* The non-packed data structures require 8 byte alignment.
* alignas() is not allowed to weaken alignment requirements to 4 bytes.
* Clang enforces this according to standard, GCC ignores it.
Use an additional alignas() specifier to let the compiler choose between
minimum alignment (packed) and "natural" alignment (non-packed). This is
both standard c++11 and compatible with older GCC, which does not
propagate alignment requirements of packed substructures properly.
