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.

This adds an entry to "Other implementations of the .xz format" for
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.

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.
2023-07-17 23:34:55 +08:00
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().
2023-07-17 23:34:55 +08:00
Jia Tan 3d21da5cff xz: Separate string to filter conversion into a helper function.
Converting from string to filter will also need to be done for block
specific filter chains.
2023-07-17 23:34:55 +08:00
Jia Tan a6583726e5 Tests: Use new --filters option in test_compress.sh 2023-07-17 23:34:55 +08:00
Jia Tan 5f3b898d07 xz: Update --long-help and man page for new --filters option. 2023-07-17 23:34:55 +08:00
Jia Tan 9ded880a02 xz: Add --filters option to CLI.
The --filters option uses the new lzma_str_to_filters() function
to convert a string into a full filter chain. Using this option
will reset all previous filters set by --preset, --[filter], or
--filters.

Jia Tan 2c189bb00a Tests: Improve feature testing for skipping.
Fixed a bug where test_compress_* would all fail if arm64 or armthumb
filters were enabled for compression but arm was disabled. Since the
grep tests only checked for "define HAVE_ENCODER_ARM", this would match
on HAVE_ENCODER_ARM64 or HAVE_ENCODER_ARMTHUMB.

Now the config.h feature test requires " 1" at the end to prevent the
prefix problem. have_feature() was also updated for this even though
there were known current bugs affecting it. This is just in case future
features have a similar prefix problem.

Jia Tan 17f8844e6f liblzma: Remove non-portable empty initializer.
Commit 78704f36e7 added an empty
initializer {} to prevent a warning. The empty initializer is a GNU
extension and results in a build failure on MSVC. The -wpedantic flag
warns about empty initializers.
