Lasse Collin f7fa309e1f liblzma: Make lzma_outq usable for threaded decompression too.
Before this commit all output queue buffers were allocated as
a single big allocation. Now each buffer is allocated separately
when needed. Used buffers are cached to avoid reallocation
overhead but the cache will keep only one buffer size at a time.
This should make things work OK in the decompression where most
of the time the buffer sizes will be the same but with some less
common files the buffer sizes may vary.

While this should work fine, it's still a bit preliminary
and may even get reverted if it turns out to be useless for
decompression.

H.J. Lu 4fd79b90c5 liblzma: Enable Intel CET in x86 CRC assembly codes
When Intel CET is enabled, we need to include <cet.h> in assembly codes
to mark Intel CET support and add _CET_ENDBR to indirect jump targets.

Tested on Intel Tiger Lake under CET enabled Linux.

Lasse Collin 2f108abb3d CMake: Fix compatibility with CMake 3.13.
The syntax "if(DEFINED CACHE{FOO})" requires CMake 3.14.
In some other places the code treats the cache variables
like normal variables already (${FOO} or if(FOO) is used,
not ${CACHE{FOO}).

Thanks to ygrek for reporting the bug on IRC.

Lasse Collin 4575d9d365 xz: Avoid unneeded \f escapes on the man page.
I don't want to use \c in macro arguments but groff_man(7)
suggests that \f has better portability. \f would be needed
for the .TP strings for portability reasons anyway.

Thanks to Bjarni Ingi Gislason.

Lasse Collin 620b32f533 xz: Use non-breaking spaces when intentionally using more than one space.
This silences some style checker warnings. Seems that spaces
in the beginning of a line don't need this treatment.

Lasse Collin 5d224da3da xz: Avoid the abbreviation "e.g." on the man page.
A few are simply omitted, most are converted to "for example"
and surrounded with commas. Sounds like that this is better
style, for example, man-pages(7) recommends avoiding such
abbreviations except in parenthesis.

Thanks to Bjarni Ingi Gislason.

Lasse Collin 90457dbe3e xz man page: Change \- (minus) to \(en (en-dash) for a numeric range.
Docs of ancient troff/nroff mention \(em (em-dash) but not \(en
and \- was used for both minus and en-dash. I don't know how
portable \(en is nowadays but it can be changed back if someone
complains. At least GNU groff and OpenBSD's mandoc support it.

Thanks to Bjarni Ingi Gislason for the patch.

by disabling thousands separators for DJGPP builds.

when one knows that po4a isn't available but wants autogen.sh
to still return with zero exit status.

Lasse Collin 474320e990 Build: Fix bugs in the CMake files.
Seems that the phrase "add more quotes" from sh/bash scripting
applies to CMake as well. E.g. passing an unquoted list ${FOO}
to a function that expects one argument results in only the
first element of the list being passed as an argument and
the rest get ignored. Adding quotes helps ("${FOO}").

list(INSERT ...) is weird. Inserting an empty string to an empty
variable results in empty list, but inserting it to a non-empty
variable does insert an empty element to the list.

Since INSERT requires at least one element,
"${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt.
It might result in an empty element in the list. It seems to not
matter as empty elements consistently get ignored in that variable.
In fact, calling cmake_check_push_state() and cmake_check_pop_state()
will strip the empty elements from CMAKE_REQUIRED_LIBRARIES!

In addition to quoting fixes, this fixes checks for the cache
variables in tuklib_cpucores.cmake and tuklib_physmem.cmake.

Thanks to Martin Matuška for testing and reporting the problems.
These fixes aren't tested yet but hopefully they soon will be.

Lasse Collin 7e3493d40e Build: Add very limited experimental CMake support.
This does *NOT* replace the Autotools-based build system in
the foreseeable future. See the comment in the beginning
of CMakeLists.txt.

So far this has been tested only on GNU/Linux but I commit
it anyway to make it easier for others to test. Since I
haven't played much with CMake before, it's likely that
there are things that have been done in a silly or wrong
way and need to be fixed.

Lasse Collin e094d1d0f1 tuklib: Omit an unneeded <sys/types.h> from a tests.
tuklib_cpucores.c and tuklib_physmem.c don't include <sys/types.h>
even via other files in this package, so clearly that header isn't
needed in the tests either (no one has reported build problems due
to a missing header in a .c file).

Lasse Collin 57360bb4fd tuklib_exit: Add missing header.
strerror() needs <string.h> which happened to be included via
tuklib_common.h -> tuklib_config.h -> sysdefs.h if HAVE_CONFIG_H
was defined. This wasn't tested without config.h before so it
had worked fine.

Lasse Collin fddd31175e Revert the previous commit and add a comment.
The previous commit broke crc32_tablegen.c.

If the whole package is built without config.h (with defines
set on the compiler command line) this should still work fine
as long as these headers conform to C99 well enough.
2020-02-18 19:12:35 +02:00
Lasse Collin 4e4e9fbb7e Do not check for HAVE_CONFIG_H in tuklib_config.h.
In XZ Utils sysdefs.h takes care of it and the required headers.
2020-02-17 23:37:20 +02:00
Lasse Collin 2d4cef954f sysdefs.h: Omit the conditionals around string.h and limits.h.
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.
