This new variable is extremely useful when iterating on creating a large package,
as otherwise you have to wipe the source and rebuild each time you make a mistake
with the patches or build.sh script.
Simply set TERMUX_PKG_QUICK_REBUILD=true in build.sh if a build fails and then the
TERMUX_PKG_SRCDIR and TERMUX_PKG_BUILDDIR will not be touched when you rebuild,
including that the patches will not be applied again. When you're done iterating,
diff for any new patches, save them, and remove this variable before rebuilding
from scratch, hopefully for the last time. ;)
An example is shown for the giant libllvm package, where other modifications are
also excluded if this variable is set.
Unlike the NDK clang, the on-device clang has already been patched to add an rpath
to the Termux-prefixed library path, so only have the build script add the rpath
flag for NDK builds.
termux_step_install_service_scripts is run after
termux_step_post_make_install and loops over the new array
TERMUX_PKG_SERVICE_SCRIPT to add service scripts for termux-services.
The service scripts are usually only a one-liner so we might just as
well define it in a variable like TERMUX_PKG_SERVICE_SCRIPT.
TERMUX_PKG_SERVICE_SCRIPT should be an array on the format
("daemon-name" 'script to execute' "another daemon" 'multi\n line\n script'),
i.e. it should be of even length with name + script where the script
part preferably is within single quotes (to avoid accidental expansion
of for example $HOME).
By defining __TERMUX__ and __TERMUX_PREFIX__ in <sys/cdefs.h> (which is
basically always included) one can more easily target Termux
specifically, both when cross-compiling packages and when code is built
on-device.
posix_spawn is not available on Android devices.
While this commit is not necessary for cross-compiling, it is required
when building on-device since there posix_spawn is found somehow. This
produces following errors:
./spawn.h:514:17: error: use of undeclared identifier 'POSIX_SPAWN_RESETIDS'

should not accept arbitrary values for marking them "enabled". Instead
they should accept boolean values which makes them easier to handle and
also makes their meaning clear.
build-package.sh should make decision based on variable's value but not on
whether it is set or empty.
%ci:no-build
Partial compatibility for on-device builds.
There is no guarantee that it will be possible to build all available
packages and built packages will have same reliability that cross-compiled
but should solve "self-hosting" problems as much as possible.
Do not use pipes for building & uploading packages because:
* They spawn more jobs on Bintray for metadata generation - each upload is
done in a separate session.
* Bintray doesn't handle well concurrent uploads and metadata can be corrupted.
This happened in all recent builds of platform independent packages - in
each upload task file had a same name and that triggered problem with metadata.
* Using delays for workaround for a problem described above works, but isn't
safe.
CI periodically shows error like
Failed to decrypt some environment variables
so it will be better to stop immediately when environment is inconsistent
for unknown reason (e.g. due to Github's problems).
All platform independent packages affected by this issue. Results in
persistent apt error like:
Writing more data than expected (22610650 > 22610408)
Hashes of expected file:
- SHA256:08abc5cffb9e1967fab487a471bb547f5ae706c48bf8e59d1443b2ad4af9caaf
- SHA1:36ded1e207135bdeb8b7301bc03309ebced3cd32 [weak]
- Filesize:22610408 [weak]
In certain cases Bintray may return errors like `invalid version a.b.c` for
specific tasks. This probably happens because we now running package uploading in
parallel.
Retrying upload one more time should fix the problem.
* Move package building/uploading implementation from config to a separate script.
* Implement new tag '%ci:no-build' to allow immediately stop build with status 'passed'.
