It quite probably was never needed, that is, any system where memory.h
was required likely couldn't compile XZ Utils for other reasons anyway.
XZ Utils 5.2.6 and later source packages were generated using
Autoconf 2.71 which no longer defines HAVE_MEMORY_H. So the code
being removed is no longer used anyway.
string.h is used unconditionally elsewhere in the project and
configure has always stopped if limits.h is missing, so these
headers must have been always available even on the weirdest
systems.
The non-standard ones from msvcrt.dll appear to work
most of the time with XZ Utils, but there are some
corner cases where things may go very wrong. So it's
good to use the better replacements provided by
MinGW(-w64) runtime.
Separate a few reusable components from XZ Utils specific
code. The reusable code is now in "tuklib" modules. A few
more could be separated still, e.g. bswap.h.
Fix some bugs in lzmainfo.
Fix physmem and cpucores code on OS/2. Thanks to Elbert Pol
for help.
Add OpenVMS support into physmem. Add a few #ifdefs to ease
building XZ Utils on OpenVMS. Thanks to Jouk Jansen for the
original patch.
- Updated to the latest, probably final file format version.
- Command line tool reworked to not use threads anymore.
Threading will probably go into liblzma anyway.
- Memory usage limit is now about 30 % for uncompression
and about 90 % for compression.
- Progress indicator with --verbose
- Simplified --help and full --long-help
- Upgraded to the last LGPLv2.1+ getopt_long from gnulib.
- Some bug fixes
broken. API has changed a lot and it will still change a
little more here and there. The command line tool doesn't
have all the required changes to reflect the API changes, so
it's easy to get "internal error" or trigger assertions.
or no inttypes.h. This is useful when the compiler has
good enough support for C99, but libc headers don't.
Changed liblzma API so that sys/types.h and inttypes.h
have to be #included before #including lzma.h. On systems
that don't have C99 inttypes.h, it's the problem of the
applications to provide the required types and macros
before #including lzma.h.
If lzma.h defined the missing types and macros, it could
conflict with third-party applications whose configure
has detected that the types are missing and defined them
in config.h already. An alternative would have been
introducing lzma_uint32 and similar types, but that would
just be an extra pain on modern systems.
