Jia Tan 39f4a1a86a Tests: Add MicroLZMA test. 2024-02-23 20:58:36 +08:00
Lasse Collin 74e8bc7417 CMake: Add test_scripts.sh to the tests.
In contrast to Automake, skipping of this test when decoders
are disabled is handled at CMake side instead of test_scripts.sh
because CMake-build doesn't create config.h.

Lasse Collin 5394a1665b Tests: tuktest.h: Treat Clang separately from GCC.
Don't assume that Clang defines __GNUC__ as the extensions

Jia Tan d0b24efe6c Tests: Silence -Wsign-conversion warning on GCC version < 10.
Since GCC version 10, GCC no longer complains about simple implicit
integer conversions with Arithmetic operators.

For instance:

    uint8_t a = 5;
    uint32_t b = a + 5;

Give a warning on GCC 9 and earlier but this:

    uint8_t a = 5;
    uint32_t b = (a + 5) * 2;

Gives a warning with GCC 10+.

Jia Tan ee2f483500 Tests: Minor cleanups to OSS-Fuzz files.
Most of these fixes are small typos and tweaks. A few were caused by bad
advice from me. Here is the summary of what is changed:

- Author line edits

- Small comment changes/additions

- Using the return value in the error messages in the fuzz targets'
  coder initialization code

- Removed fuzz_encode_stream.options. This set a max length, which may
  prevent some worthwhile code paths from being properly exercised.

- Removed the max_len option from fuzz_decode_stream.options for the
  same reason as fuzz_encode_stream. The alone decoder fuzz target still
  has this restriction.

- Altered the dictionary contents for fuzz_lzma.dict. Instead of keeping
  the properties static and varying the dictionary size, the properties
  are varied and the dictionary size is kept small. The dictionary size
  doesn't have much impact on the code paths but the properties do.

Closes: https://github.com/tukaani-project/xz/pull/73

Maksym Vatsyk 483bb90eec Tests: Add fuzz_encode_stream ossfuzz target.
This fuzz target handles .xz stream encoding. The first byte of input
is used to dynamically set the preset level in order to increase the
fuzz coverage of complex critical code paths.
2023-12-07 20:06:57 +08:00
Maksym Vatsyk 7ca8c9869d Tests: Add fuzz_decode_alone OSS-Fuzz target
This fuzz target that handles LZMA alone decoding. A new fuzz
dictionary .dict was also created with common LZMA header values to
help speed up the discovery of valid headers.

Maksym Vatsyk 37581a77ad Tests: Update OSS-Fuzz Makefile.

Makefile target for each fuzz target.

Jia Tan ca278eb2b7 Tests: Create test_suffix.sh.
This tests some complicated interactions with the --suffix= option.
The suffix option must be used with --format=raw, but can optionally
be used to override the default .xz suffix.

This test also verifies some recent bugs have been correctly solved
and to hopefully avoid further regressions in the future.

Previously if the lzip decoder was not configured then test_files.sh

Jia Tan 194d12724b Tests: Add ARM64 filter test to test_compress.sh. 2023-07-20 22:11:13 +08:00
Jia Tan a6583726e5 Tests: Use new --filters option in test_compress.sh 2023-07-17 23:34:55 +08:00
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 66bdcfa85f Tests: Fix memory leaks in test_index.
Several tests were missing calls to lzma_index_end() to clean up the
lzma_index structs. The memory leaks were discovered by using
-fsanitize=address with GCC.
2023-06-29 00:07:16 +08:00
Jia Tan fe3bd438fb Tests: Fix memory leaks in test_block_header.
test_block_header was not properly freeing the filter options between
calls to lzma_block_header_decode(). The memory leaks were discovered by
using -fsanitize=address with GCC.

Jia Tan 9aa7fdeb04 Tests: Small tweak to test-vli.c.
The static global variables can be disabled if encoders and decoders

Lasse Collin bfc3a0a8ac Tests: Fix warnings from clang --Wassign-enum.
Explicitly casting the integer to lzma_check silences the warning.
Since such an invalid value is needed in multiple tests, a constant
INVALID_LZMA_CHECK_ID was added to tests.h.

The use of 0x1000 for lzma_block.check wasn't optimal as if
the underlying type is a char then 0x1000 will be truncated to 0.
However, in these test cases the value is ignored, thus even with
such truncation the test would have passed.
2023-01-12 04:14:18 +02:00
Lasse Collin 49245bb31e Tests: Silence warnings from -Wsign-conversion.
Note that assigning an unsigned int to lzma_check doesn't warn
on GNU/Linux x86-64 since the enum type is unsigned on that
platform. The enum can be signed on some other platform though
so it's best to use enumeration type lzma_check in these situations.

Jia Tan 25035813d1 Tests: Fix type-limits warning in test_filter_flags.
This only occurs in test_filter_flags when the BCJ filters are not
configured and built. In this case, ARRAY_SIZE() returns 0 and causes a
type-limits warning with the loop variable since an unsigned number will
always be >= 0.

Jia Tan 765354b50c Tests: Fix unused function warning in test_block_header.

Jia Tan 7c23c05bef Tests: Fix unused function warning in test_index_hash.

Lasse Collin 0c210ca7f4 Tests: test_filter_flags: Clean up minor issues.
Here are the list of the most significant issues addressed:
- Avoid using internal common.h header. It's not good to copy the
constants like this but common.h cannot be included for use outside
of liblzma. This is the quickest thing to do that could be fixed later.

- Omit the INIT_FILTER macro. Initialization should be done with just
regular designated initializers.

- Use start_offset = 257 for BCJ tests. It demonstrates that Filter
Flags encoder and decoder don't validate the options thoroughly.
257 is valid only for the x86 filter. This is a bit silly but
not a significant problem in practice because the encoder and
decoder initialization functions will catch bad alignment still.
Perhaps this should be fixed but it's not urgent and doesn't need
to be in 5.4.x.

- Various tweaks to comments such as filter id -> Filter ID

Lasse Collin 0e1545fea3 Tests: tuktest.h: Support tuktest_malloc(0).
It's not needed in XZ Utils at least for now. It's good to support
it still because if such use is needed later, it wouldn't be
caught on GNU/Linux since malloc(0) from glibc returns non-NULL.

Lasse Collin 05c72de06f Tests: test_files.sh: Make it not fail if features were disabled at build.
It now tries to test as many files as easily possible.
The exit status indicates skipping if any of the files were
skipped. This way it is easy to notice if something is being
skipped when it isn't expected.
2022-10-27 15:49:18 +03:00
Lasse Collin b3459327a5 Tests: test_files.sh: Suppress an expected warning from the log.
xz (but not xzdec) will normally warn about unsupported check
but since we are testing specifically such a file, it's better
to silence that warning so that it doesn't look suspicious in
test_files.sh.log.

The use of -q and -Q in xzdec is just for consistency and
doesn't affect the result at least for now.

Lasse Collin 424ac91c7e Tests: Skip tests in test_*.sh if encoders and/or decoders are disabled.
This isn't perfect as the scripts can still fail if only
certain filters are disabled. This is still an improvement
as now "make check" has better behavior when all encoders
or decoders are disabled.

Grepping ../config.h is simple and fairly clean but it only
works if config.h was created. CMake builds don't create
config.h but they don't use these test scripts either.

Thanks to Sebastian Andrzej Siewior for reporting the problem.
Thanks to Jia Tan for the original patch which grepped xz
error messages instead of config.h.
2022-10-19 19:39:35 +03:00
Lasse Collin ca8bf9d7c5 Test: Remove the (exit 1) lines.
I suspect that I used these in the original version because
Autoconf's manual describes that such a trick is needed in
some specific situations for portability reasons. None of those
situations listed on Autoconf 2.71 manual apply to these test
scripts though so this cleans them up.

Normal decompression doesn't use lzma_index_append() at all.
Instead, lzma_index_hash functions are used and those already
did the overflow check.

Lasse Collin f2d084fe3f Tests: Silence warnings about unused functions from tuktest.h.
Warnings about unused tuktest_run_test conveniently tell which

It is fine to use __attribute__((__unused__)) even when the
function is actually used because the attribute only means
that the function might be unused.
