NOTE: This commit only tested on Linux (Ubuntu 18.04). Windows
build may not work as expected.
* Use meson >= 0.47.0 cause we use install_man function
* Add three helper Python script:
* CopyFile.py: To copy file
* CreateSymlink.py: To make symlink (both Windows and Unix)
* GetZstdLibraryVersion.py: Parse lib/zstd.h to get zstd version
These help emulating equivalent functions in CMake and Makefile.
* Use subdir from meson to split meson.build
* Add contrib build
* Fix other build
* Add new build options
* build_programs: Enable programs build
* build_contrib: Enable contrib build
* build_tests: Enable tests build
* use_static_runtime: Link to static run-time libraries on MSVC
* zlib_support: Enable zlib support
* lzma_support: Enable lzma support
constants that *may* change in the future
will be accessed through functions instead
(to be created).
_simpleArgs() variant do not have (yet) a clear enough added value
to deserve "stable" status.
When multiple -arch flags are used, the compiler invokes itself once for
each architecture. Apparently, input on stdin is consumed by the
compilation of the first arch and is no longer available to the
compilation of the second arch, which results in a build failure and the
potentially incorrect determination that a feature is not available. So
write the feature detection source to a file instead of using stdin.
- Factor out LDM's hash function for reuse
- Add rsyncable mode to zstdmt and expose it via the advanced API
- Fix `-B`/`--block-size` to actually set the job size
- Add rsyncable tests to `zstreamtest` and `playTests.sh`
Tested by:
```
> cat A.100MB B.100MB C.100MB D.100MB E.100MB | zstd --rsyncable -fo src/file.zst
/*stdin*\ : 48.22% (524288000 => 252837782 bytes, src/file.zst)
> rsync -rc --stats src devbigvm:/data/users/terrelln/rsync-test
Total bytes sent: 252868779
total size is 252837782 speedup is 1.00

Close#1155.
which now accepts an enum,
to distinguish between resetting the session, or the parameters (or both).
removed ZSTD_CCtx_resetParameters(), which is redundant.
start replacing invocation of ZSTD_CCtx_reset*() functions
Updated advanced API documentation
trimmed down amount of API staged in RC,
in particular, all functions related to ZSTD_CCtxParams()
seem too advanced.
answering #1407.
Also : removed obsolete function ZSTD_setDStreamParameter()
which could only be used with one parameter (DStream_p_maxWindowSize).
Now replaced by ZSTD_DCtx_setWindowSize() (which exists since a few revisions)
