* Use fstat() to determine file size.Niklas Hambüchen2020-08-242-3/+28
| | | | | | | | | | | | This allows us to get the file size even when the input file is passed via stdin. This fixes `--content-size` not working in situations like $ lz4 -v --content-size < /tmp/test > /tmp/test.lz4 Warning : cannot determine input content size With this change, it works. Also helps with #904.
* added target lz4-wlibYann Collet2020-08-112-6/+21
| | | | | | | | variant of lz4 linking to liblz4 dynamic library requires the dynamic library to expose static-only symbols (experimental API) Example for #888

* Make benchmark compatible with dictionary compressionReto Koradi2019-11-063-53/+244
| | | | | | | | | | | | | | | Support the -D command line option for running benchmarks. The benchmark code was slightly restructured to factor out the calls that need to be different for each benchmark scenario. Since there are now 4 scenarios (all combinations of fast/HC and with/without dictionary), the logic was getting somewhat convoluted otherwise. This was done by extending the compressionParameters struct that previously contained just a single function pointer. It now contains 4 function pointers for init/reset/compress/cleanup, with the related state. The functions get a pointer to the structure as their first argument (inspired by C++), so that they can access the state values in the struct.
* util.h: Remove deprecated utime for non-WindowsRosen Penev2019-09-102-6/+20

* bumped version number to v1.9.2Yann Collet2019-07-012-9/+9

* More build imrpvementsJPeterMugaas2019-04-232-21/+59
| | | | | | Moved a few other tests to Makefiles.inc. Other things might need to go there. Made a test for symlink appropriateness. Windows can NOT handle them the same way Unix-like operating systems do (if at all). This is mostly the same as the Visual C projects. embed version info into .dll and .exes that are redistributed.

* | | ensure tests work when `stdout` is not the consoleYann Collet2019-04-222-16/+16
| | | | | | | | | | | | | | | | | | | | | ensure this case is continuously tested on travis. Update documentation on implicit output, invite to not rely on implicit output in scripts.
* | | cli: display a warning whenever default output is stdout while input != stdinYann Collet2019-04-201-11/+25
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | This behavior has been preserved for compatibility with existing ecosystem. But it's problematic, as some environment start `lz4` without identifying stdout as console by default, leading to a change of behavior for a same line of script. A more sensible policy would be to default to stdout only when input is stdin. Soft change for the time being : keep the behavior, just print a warning message. User should prefer `-c` to explicitly select `stdout`. Also : updated tests in Makefile to explicitly select `stdout` with `-c`.

* added command -BI for "Independent Blocks"Yann Collet2019-04-123-13/+22
| | | | | | | | This is the reverse of `-BD`, and the current default. This command can be useful to reverse a previous `-BD` command. It may in the future be more important if `lz4` switches to generating dependent blocks by default.
