Jia Tan a08f5ccf6b Created tests for all functions exported in vli.h
Achieved 100% code coverage vli_encoder.c, vli_decoder.c, and vli_size.c

Lasse Collin 00e3613f12 Tests: Use good-1-empty-bcj-lzma2.xz in test_bcj_exact_size.
It's much nicer this way so that the test data isn't a hardcoded
table inside the C file.

Lasse Collin f9e8176ea7 Tests: Add test file good-1-empty-bcj-lzma2.xz.
This is from test_bcj_exact_size.c.
It's good to have it as a standalone file.

Jia Tan aa75c5563a Tests: Created tests for hardware functions.
Created tests for all API functions exported in
src/liblzma/api/lzma/hardware.h. The tests are fairly trivial
but are helpful because they will inform users if their machines
cannot support these functions. They also improve the code
coverage metrics.

Lasse Collin 5c8ffdca20 Tests: Convert test_check to tuktest.
Thanks to Jia Tan for help with all the tests.

Lasse Collin faf5ff8899 Tests: Convert test_block_header to tuktest. 2022-06-02 20:45:05 +03:00
Lasse Collin 754d39fbeb Tests: Convert test_bcj_exact_size to tuktest.
The compress() and decompress() functions were merged because
the later depends on the former so they need to be a single
test case.
2022-06-02 20:28:23 +03:00
Lasse Collin 96da21470f Tests: Include tuktest.h in tests.h.
This breaks -Werror because none of the tests so far use
tuktest.h and thus there are warnings about unused variables
and functions.

Lasse Collin df71ba1c99 Tests: Add tuktest.h mini-test-framework. 2022-06-02 20:25:21 +03:00
Lasse Collin 9a6dd6d46f Tests: Split test_compress.sh into separate test unit for each file.
test_compress.sh now takes one command line argument:
a filename to be tested. If it begins with "compress_generated_"
the file will be created with create_compress_files.

This will allow parallel execution of the slow tests.
2022-05-23 21:31:20 +03:00
Lasse Collin c7758ac9c7 Test: Make create_compress_files.c a little more flexible.
If a command line argument is given, then only the test file
of that type is created. It's quite dumb in sense that unknown
names don't give an error but it's good enough here.

Also use EXIT_FAILURE instead of 1 as exit status for errors.

Lasse Collin e873902641 Tests: Silence warnings from clang -Wassign-enum.
Also changed 999 to 99 so it fits even if lzma_check happened
to be 8 bits wide.

The duplication was introduced about eleven years ago and
should have been cleaned up back then already.

This was caught by -Wduplicated-branches.

Lasse Collin d2d484647d Tests: Don't hide unexpected error messages in test_files.sh.
Hiding them makes no sense since normally there's no error
when testing the "good" files. With "bad" files errors are
expected and then it makes sense to keep the messages hidden.
2015-01-06 20:30:15 +02:00

version by Pavel Raiskup.
2014-06-13 18:58:22 +03:00
Lasse Collin 1e60f2c0a0 xzgrep: Add a test for the previous fix.
This is a simplified version of Pavel Raiskup's
original patch.

Lasse Collin d8db706acb liblzma: Fix possibility of incorrect LZMA_BUF_ERROR.
lzma_code() could incorrectly return LZMA_BUF_ERROR if
all of the following was true:

  - The caller knows how many bytes of output to expect
    and only provides that much output space.

  - When the last output bytes are decoded, the
    caller-provided input buffer ends right before
    the LZMA2 end of payload marker. So LZMA2 won't
    provide more output anymore, but it won't know it
    yet and thus won't return LZMA_STREAM_END yet.

  - A BCJ filter is in use and it hasn't left any
    unfiltered bytes in the temp buffer. This can happen
    with any BCJ filter, but in practice it's more likely
    with filters other than the x86 BCJ.

Another situation where the bug can be triggered happens
if the uncompressed size is zero bytes and no output space
is provided. In this case the decompression can fail even
if the whole input file is given to lzma_code().

A similar bug was fixed in XZ Embedded on 2011-09-19.

Lasse Collin bd52cf150e Build: Fix "make check" on Windows. 2011-09-06 12:03:41 +03:00
Lasse Collin e9ed88126e Run the scripts with the correct shell in test_scripts.sh.
The scripts are now made executable in the build tree.
This way the scripts can be run like programs in
test_scripts.sh. Previously test_scripts.sh always
used sh but it's not correct if @POSIX_SHELL@ is set
to something else by configure.

Thanks to Jonathan Nieder for the patch.
2011-08-06 20:37:28 +03:00
Lasse Collin 1c673e5681 Fix exit status of "xzdiff foo.xz bar.xz".
xzdiff was clobbering the exit status from diff in a case
statement used to analyze the exit statuses from "xz" when
its operands were two compressed files. Save and restore
diff's exit status to fix this.

The bug is inherited from zdiff in GNU gzip and was fixed
there on 2009-10-09.

Thanks to Jonathan Nieder for the patch and
to Peter Pallinger for reporting the bug.

For some reason this prevented running the test only
on OS/2 and even on that it broke only recently.

Thanks to Elbert Pol.

Lasse Collin 11f51b6714 Make tests accommodate missing xz or xzdec. 2010-10-08 15:32:29 +03:00
Lasse Collin f9907503f8 Build: Remove the static/dynamic tricks.
Most distros want xz linked against shared liblzma, so
it doesn't help much to require --enable-dynamic for that.
Those who want to avoid PIC on x86-32 to get better
performance, can still do it e.g. by using --disable-shared
to compile xz and then another pass to compile shared liblzma.

Part of these static/dynamic tricks were needed for Windows
in the past. Nowadays we rely on GCC and binutils to do the
right thing with auto-import. If the Autotooled build system
needs to support some other toolchain on Windows in the future,
this may need some rethinking.

Lasse Collin 1a7ec87c8e Revised the Index handling code.
This breaks API and ABI but most apps are not affected
since most apps don't use this part of the API. You will
get a compile error if you are using anything that got
broken.

Summary of changes:

  - Ability to store Stream Flags, which are needed
    for random-access reading in multi-Stream files.

  - Separate function to set size of Stream Padding.

  - Iterator structure makes it possible to read the same
    lzma_index from multiple threads at the same time.

  - A lot faster code to locate Blocks.

  - Removed lzma_index_equal() without adding anything
    to replace it. I don't know what it should do exactly
    with the new features and what actually needs this
    function in the first place other than test_index.c,
    which now has its own code to compare lzma_indexes.
2009-12-31 22:45:53 +02:00
Lasse Collin 8767b41534 Fix a memory leak in test_index.c.
This was introduced in
bd13b04e20.

Thanks to Jim Meyering for noticing it.
2009-11-26 10:10:36 +02:00
Lasse Collin bd13b04e20 Fix bugs in lzma_index_read() and lzma_index_cat().
lzma_index_read() didn't skip over Stream Padding
if it was the first record in the Index.

lzma_index_cat() didn't combine small Indexes correctly.

The test suite was updated to check for these bugs.

These bugs didn't affect the xz command line tool or
most users of liblzma in any way.
2009-11-25 13:04:10 +02:00
Lasse Collin ebfb2c5e1f Use a tuklib module for integer handling.
This replaces bswap.h and integer.h.

The tuklib module uses <byteswap.h> on GNU,
<sys/endian.h> on *BSDs and <sys/byteorder.h>
on Solaris, which may contain optimized code
like inline assembly.
2009-10-04 22:57:12 +03:00

Lasse Collin 02ddf09bc3 Put the interesting parts of XZ Utils into the public domain.
Some minor documentation cleanups were made at the same time.
2009-04-13 11:27:40 +03:00
Lasse Collin 975d8fd72a Recreated the BCJ test files for x86 and SPARC. The old files
were linked with crt*.o, which are copyrighted, and thus the
old test files were not in the public domain as a whole. They
are freely distributable though, but it is better to be careful
and avoid including any copyrighted pieces in the test files.
The new files are just compiled and assembled object files,
and thus don't contain any copyrighted code.
2009-02-06 09:13:15 +02:00
Lasse Collin 6a2eb54092 Add LZMA_API to liblzma API headers. It's useful at least
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h
has to be #included separately where needed.

2008-12-31 18:59:02 +02:00
Lasse Collin 322ecf93c9 Renamed lzma_options_simple to lzma_options_bcj in the API.
The internal implementation is still using the name "simple".
It may need some cleanups, so I look at it later.
2008-12-31 16:29:39 +02:00
Lasse Collin 7ed9d943b3 Remove lzma_init() and other init functions from liblzma API.
Half of developers were already forgetting to use these
functions, which could have caused total breakage in some future
liblzma version or even now if --enable-small was used. Now
liblzma uses pthread_once() to do the initializations unless
it has been built with --disable-threads which make these
initializations thread-unsafe.

When --enable-small isn't used, liblzma currently gets needlessly
linked against libpthread (on systems that have it). While it is
stupid for now, liblzma will need threads in future anyway, so
this stupidity will be temporary only.

When --enable-small is used, different code CRC32 and CRC64 is
now used than without --enable-small. This made the resulting
binary slightly smaller, but the main reason was to clean it up
and to handle the lack of lzma_init_check().

The pkg-config file lzma.pc was renamed to liblzma.pc. I'm not
sure if it works correctly and portably for static linking
(Libs.private includes -pthread or other operating system
specific flags). Hopefully someone complains if it is bad.

lzma_rc_prices[] is now included as a precomputed array even
with --enable-small. It's just 128 bytes now that it uses uint8_t
instead of uint32_t. Smaller array seemed to be at least as fast
as the more bloated uint32_t array on x86; hopefully it's not bad
on other architectures.

Lasse Collin 1880a3927b Renamed lzma to xz and lzmadec to xzdec. We create symlinks
lzma, unlzma, and lzcat in "make install" for backwards
compatibility with LZMA Utils 4.32.x; I'm not sure if this
should be the default though.
2008-11-19 23:52:24 +02:00
Lasse Collin e114502b2b Oh well, big messy commit again. Some highlights:
- 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
2008-11-19 20:46:52 +02:00
Lasse Collin 3c3905b534 Fixed the test that should have been fixed as part

Lasse Collin 3b34851de1 Sort of garbage collection commit. :-| Many things are still
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.

2008-06-18 19:19:02 +03:00
Lasse Collin 7d17818cec Update the code to mostly match the new simpler file format
specification. Simplify things by removing most of the
support for known uncompressed size in most places.
There are some miscellaneous changes here and there too.

The API of liblzma has got many changes and still some
more will be done soon. While most of the code has been
updated, some things are not fixed (the command line tool
will choke with invalid filter chain, if nothing else).

Subblock filter is somewhat broken for now. It will be
updated once the encoded format of the Subblock filter
has been decided.

2008-01-23 20:05:01 +02:00
Lasse Collin 99e12af4e2 Fix Size of Header Metadata Block handling. Now
lzma_metadata.header_metadata_size == LZMA_VLI_VALUE_UNKNOWN
is not allowed at all. To indicate missing Header Metadata
Block, header_metadata_size must be set to zero. This is
what Metadata decoder does after this patch too.

Note that other missing fields in lzma_metadata are still
indicated with LZMA_VLI_VALUE_UNKNOWN. This isn't as
illogical as it sounds at first, because missing Size of
Header Metadata Block means that Header Metadata Block is
not present in the Stream. With other Metadata fields,
