Jia Tan 6497d1f887 CI: Windows CI rename system matrix variable -> msys2_env.
Calling the MSYS2 environment "system" was a bit vague and should be
more specific.

Jia Tan 785e4121d9 CI: Add Clang64 MSYS2 environment to Windows CI. 2023-07-24 23:11:45 +08:00
Jia Tan d9166b52cf liblzma: Prevent an empty translation unit in Windows builds.
To workaround Automake lacking Windows resource compiler support, an
empty source file is compiled to overwrite the resource files for static
library builds. Translation units without an external declaration are
not allowed by the C standard and result in a warning when used with
-Wempty-translation-unit (Clang) or -pedantic (GCC).

Jia Tan f3a055f762 CI: Add Windows runner for Autotools builds with MSYS2.
Only a subset of the tests run by the Linux and MacOS Autotools builds
are run. The most interesting tests are the ones that disable threads,
encoders, and decoders.

The Windows runner will only be run manually since these tests will
likely take much longer than the Linux and MacOS runners. This runner
should be used before merging any large features and before releases.

Currently the clang64 environment fails to due to a warning and
-Werror is enabled for the CI tests. This is still an early version
since the CMake build can be done for MSVC and optionally each of the
MSYS2 environments. GitHub does not allow manually running the CI tests
unless the workflow is checked on the default branch so checking in a
minimum version is a good idea.

Thanks to Arthur S for the original proposing the original patch.

Jia Tan 39a32d36fc Tests: Skip .lz files in test_files.sh if not configured.
Previously if the lzip decoder was not configured then test_files.sh
would pass the lzip tests instead of skipping them.

Jia Tan 0184d344fa liblzma: Suppress -Wunused-function warning.
Clang 16.0.0 and earlier have a bug that the ifunc resolver function
triggers the -Wunused-function warning. The resolver function is static
and only "used" by the __attribute__((__ifunc()__)).

At this time, the bug is still unresolved, but has been reported:
https://github.com/llvm/llvm-project/issues/63957

This is not a problem in GCC.

Jia Tan 43845fa70f liblzma: Reword lzma_str_list_filters() documentation.
This further improves the documentation from commit
f36ca7982f. The previous wording of
"supported options" was slightly misleading since the options that are
printed are the ones that are relevant for encoding/decoding. It is not
about which options can or must be specified.

Jia Tan 818701ba1c liblzma: Improve comment in string_conversion.c.
The comment used "flag" when referring to decoder options. Just
referring to them as options is more clear and consistent.

Lasse Collin b6b7d06585 xz: Translate the second "%s: " in message.c since French needs "%s : ".
This string is used to print a filename when using "xz -v" and
stderr isn't a terminal.

Jia Tan 289034a168 Docs: Add a new section to INSTALL for Tests.
The new Tests section describes basic information about the tests, how
to run them, and important details when cross compiling. We have had a
few questions about how to compile the tests without running them, so
hopefully this information will help others with the same question in the
future.

XZ for Java.

Jia Tan f99e2e4e53 xz: Fix typo in man page.
The Memory limit information section described three output
columns when it actually has six. This was reworded to
"multiple" to make it more future proof.

Jia Tan f907705eb1 xz: Minor clean up for coder.c
* Moved max_block_list_size from a global to local variable.
* Reworded error message in validate_block_list_filter().
* Removed helper function filter_chain_error().
* Changed 1 << X to 1U << X in many places

Jia Tan c12e429f26 xz: Add a section to man page for robot mode --filters-help. 2023-07-17 23:34:55 +08:00
Jia Tan e10f2db5d1 xz: Slight reword in xz man page for consistency.
Changed will print => prints in xz --robot --version description to
match --robot --info-memory description.

Jia Tan f5dc172a40 xz: Reorder robot mode subsections in the man page.
The order is now consistent with the order the command line arguments
are documented earlier in the man page. The new order is:
1. --list
2. --info-memory
3. --version

Instead of the previous order:
1. --version
2. --info-memory
3. --list

Jia Tan 9628be23ae xz: Update man page for new --filters-help option. 2023-07-17 23:34:55 +08:00
Jia Tan a165d7df19 xz: Add a new --filters-help option.
The --filters-help can be used to help create filter chains with the
--filters and --filtersX options. The message in --long-help is too
short to fully explain the syntax to construct complex filter chains.

In --robot mode, xz will only print the output from liblzma function
lzma_str_list_filters.
2023-07-17 23:34:55 +08:00
Jia Tan 95f1a414b1 xz: Update the man page for --block-list and --filtersX
The --block-list option description needed updating since the new
--filtersX option changes how it can be used. The new entry for
--filters1=FILTERS ... --filter9=FILTERS was created right after
the --filters option.
2023-07-17 23:34:55 +08:00
Jia Tan 47a63cad2a xz: Update --long-help for the new --filtersX option. 2023-07-17 23:34:55 +08:00
Jia Tan 8b9913a13d xz: Ignore filter chains that are set but never used in --block-list.
If a filter chain is set but not used in --block-list, it introduced
unexpected behavior such as requiring an unneeded amount of memory to
compress, reducing the number of threads in multi-threaded encoding, and
printing an incorrect amount of memory needed to decompress.

This also renames filters_init_mask => filters_used_mask. A filter is
assumed to be used if it is specified in --filtersX until
coder_set_compression_settings() determines which filters are referenced
in --block-list.

Jia Tan 183819bfd9 xz: Set the Block size for mt encoding correctly.
When opt_block_size is not used, the Block size for mt encoder is
derived from the minimum of the largest Block specified by
--block-list and the recommended Block size on all filter chains
calculated by lzma_mt_block_size(). This avoids using unnecessary
memory and ensures that all Blocks are large enough for the most memory
needy filter chain.

Jia Tan afb2dbec3d xz: Validate --flush-timeout for all specified filter chains. 2023-07-17 23:34:55 +08:00
Jia Tan 5f0c5a0438 xz: Allows --block-list filters to scale down memory usage.
Previously, only the default filter chain could have its memory usage
adjusted. The filter chains specified with --filtersX were not checked
for memory usage. Now, all used filter chains will be adjusted if
necessary.
2023-07-17 23:34:55 +08:00
Jia Tan 479fd58d60 xz: Do not include block splitting if encoders are disabled.
The block splitting logic and split_block() function are not needed if
encoders are disabled. This will help slightly reduce the binary size
when built without encoders and allow split_block() to use functions
that require encoders being enabled.
2023-07-17 23:34:55 +08:00
Jia Tan f86ede2250 xz: Free filters[] in debug mode.
This will only free filter chains created with --filters1-9 since the
default filter chain may be set from a static function variable. The
complexity to free the default filter chain is not worth the burden on
code maintenance.
2023-07-17 23:34:55 +08:00
Jia Tan f281cd0d69 xz: Add a message if --block-list is used outside of xz compresssion.
--block-list is only supported with compression in xz format. This avoids
silently ignoring when --block-list is unused.
2023-07-17 23:34:55 +08:00
Jia Tan d6af7f3470 xz: Create command line options for filters[1-9].
The new command line options are meant to be combined with --block-list.
They work as an optional extension to --block-list to specify a custom
filter chain for each block listed. The new options allow the creation
of up to 9 reusable filter chains. For instance:

xz --block-list=1:10MiB,3:5MiB,,2:5MiB,1:0 --filters1=delta--lzma2 \
--filters2=x86--lzma2 --filters3=arm64--lzma2

Will create the following blocks:
1. A block of size 10 MiB with filter chain delta, lzma2.
2. A block of size 5 MiB with filter chain arm64, lzma2.
3. A block of size 5 MiB with filter chain arm64, lzma2.
4. A block of size 5 MiB with filter chain x86, lzma2.
5. A block containing the rest of the file contents with filter chain
   delta, lzma2.

Jia Tan 072d292501 xz: Use lzma_filters_free() in forget_filter_chain().
This is a little cleaner than the previous implementation of
forget_filter_chain(). It is also more consistent since
lzma_str_to_filters() will always terminate the filter chain so there
is no need to terminate it later in coder_set_compression_settings().
