It's not needed in XZ Utils at least for now. It's good to support
it still because if such use is needed later, it wouldn't be
caught on GNU/Linux since malloc(0) from glibc returns non-NULL.
The command line tools cannot be built with MSVC for now but
they can be built with MinGW-w64.
Thanks to Iouri Kharon for the bug report and the original patch.
The old version used too many runners that resulted in unnecessary
dependency downloads. Now, the runners are reused for the different
configurations for each OS and build system.
The new PHASE argument can be build, test, or all. all is the default.
This way, the CI/CD script can differentiate between the build and test
phases to make it easier to track down errors when they happen.
common/index.h is needed by liblzma internally and tests. common.h will
include and define many things that are not needed by the tests. Also,
this prevents include order problems because common.h will redefine
LZMA_API resulting in a warning.
The shell parameter expansion using # and ## is not supported in
Solaris 10 Bourne shell (/bin/sh). Even though this is POSIX, it is not fully
portable, so we should avoid it.
5.5.0alpha won't be released, it's just to mark that
the branch is not for stable 5.4.x.
Once again there is no API/ABI stability for new features
in devel versions. The major soname won't be bumped even
if API/ABI of new features breaks between devel releases.
HAVE_DECL_PROGRAM_INVOCATION_NAME is renamed to
HAVE_PROGRAM_INVOCATION_NAME. Previously,
HAVE_DECL_PROGRAM_INVOCATION_NAME was always set when
building with autotools. CMake would only set this when it was 1, and the
dos/config.h did not define it. The new macro definition is consistent
across build systems.
Previously, <sys/time.h> was always included, even if mythread only used
clock_gettime. <time.h> is still needed even if clock_gettime is not used
though because struct timespec is needed for mythread_condtime.
Previously, if threading was enabled HAVE_DECL_CLOCK_MONOTONIC would always
be set to 0 or 1. However, this macro was needed in xz so if xz was not
built with threading and HAVE_DECL_CLOCK_MONOTONIC was not defined but
HAVE_CLOCK_GETTIME was, it caused a warning during build. Now,
HAVE_DECL_CLOCK_MONOTONIC has been renamed to HAVE_CLOCK_MONOTONIC and
will only be set if it is 1.
The CI/CD workflow will only execute on Ubuntu and MacOS latest version.
The workflow will attempt to build with autotools and CMake and execute
the tests. The workflow will run for all pull requests and pushes done
to the master branch.
Using return_if_error on lzma_lzma_lclppb_encode was improper because
return_if_error is expecting an lzma_ret value, but
lzma_lzma_lclppb_encode returns a boolean. This could result in
lzma_microlzma_encoder, which would be misleading for applications.
Using CMake to build liblzma should work on a few other OSes
but building the command line tools is still subtly broken.
It is known that shared library versioning may differ between
CMake and Libtool builds on some OSes, most notably Darwin.
