* upstream-LibArchive:
LibArchive 2020-02-11 (3288ebb0)
Also manually restore content from upstream libarchive's main
`CMakeLists.txt` file that was removed by previous commits and
exclude it with `IF(0)` blocks. Do this as an evil merge so
that `git blame -C` can follow the content to upstream.
The SDK for macOS 10.13 adds `futimens` and `utimensat` so our checks
for these symbols may pass. However, the symbols are not available at
runtime on older macOS versions. Instead on macOS we can check for
availability based on the deployment target version.
Issue: #17101
Resolve conflicts in favor of the upstream side where possible.
Resolve a logical conflict in archive_windows.h where the upstream
port to Watcom was done slightly differently from ours.
The CMake TarTest fails with the error
mbsnrtowcs.c:116: __mbsnrtowcs: Assertion
`status == GCONV_OK || status != GCONV_EMPTY_INPUT ||
status == GCONV_ILLEGAL_INPUT || status == GCONV_INCOMPLETE_INPUT ||
status == GCONV_FULL_OUTPUT' failed.
on very old glibc versions. Work around the problem by pretending that
mbsnrtowcs does not exist. Libarchive will fall back to mbrtowc.
In libarchive/archive_platform.h we should include <stdint.h> or
<inttypes.h> immediately after "config.h" to define integer types
referenced by configuration results. For example, on a non-conformant
platform ssize_t might default to int64_t, so int64_t must be defined
before ssize_t is used (and ssize_t is used in archive_windows.h).
Some versions of Borland provide <stdint.h>, so we use it when possible.
However, the 64-bit signed and unsigned integer min/max constants cause
overflow warnings from Borland itself! For these constants we fall back
on our default definitions.
This allows for a built in bzip and zip capability, so external tools
will not be needed for these packagers. The cmake -E tar xf should be
able to handle all compression types now as well.
