Dereferencing a 0-pointer is undefined behavior, not a deterministic
crash. Use a 1-pointer instead. This also avoids a warning by Clang
about the undefined behavior.
At least one version of GNU tar (1.15.1 with Fedora patches) does not
recognize these attributes and exits with error. Do not generate them.
Patch from upstream libarchive svn r2563.
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).
The commit "libarchive: Define _XOPEN_SOURCE for get(pwu|grg)id_r"
introduced a comment referring to get(pwu|grg)id_r in a source file that
actually uses the functions get(pw|gr)name_r. We fix the comment.
The "result" argument to functions get(pwu|grg)id_r and get(pw|gr)name_r
does not appear in the signatures provided on older platforms. We set
the pointer to the result memory in case the function ignores it, thus
ensuring initialization.
The commit "Fix libarchive linker errors on SunOS for mkdev/major/minor"
hard-coded #include lines for getting mkdev/major/minor on the Sun.
Instead we add missing try-compile tests to make sure the proper headers
get included through the standard mechanism.
The commit "Fixed a few of the SunOS build errors in libarchive" changed
the call to these functions to use the old signatures. Instead we now
define _XOPEN_SOURCE to get the improved modern signatures.
The commit "libarchive: Fix Borland integer constants" introduced use of
HAVE_* configured macros into archive.h and archive_entry.h where they
are not allowed. This commit replaces the logic with something that
does not depend on the configured macros.
The VS 6 version of wincrypt.h only works if _WIN32_WINNT >= 0x0400.
We block its inclusion through windows.h by defining NOCRYPT, and then
define _WIN32_WINNT and include it only when necessary.
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.
