`zstd --decompress FILE.zst -D dictionaryName`
### Build
Once you have the repository cloned, there are multiple ways provided to build Zstandard.
#### Makefile
If your system is compatible with a standard `make` (or `gmake`) binary generator,
you can simply run it at the root directory.
It will generate `zstd` within root directory.
Other available options include :
- `make install` : create and install zstd binary, library and man page
- `make test` : create and run `zstd` and test tools on local platform
#### cmake
A `cmake` project generator is provided within `build/cmake`.
It can generate Makefiles or other build scripts
to create `zstd` binary, and `libzstd` dynamic and static libraries.
#### Visual (Windows)
Going into `build` directory, you will find additional possibilities :
- Projects for Visual Studio 2005, 2008 and 2010
+ VS2010 project is compatible with VS2012, VS2013 and VS2015
- Automated build scripts for Visual compiler by @KrzysFR , in `build/VS_scripts`,
which will build `zstd` cli and `libzstd` library without any need to open Visual Studio solution.
### Status
Zstandard is currently deployed within Facebook. It is used daily to compress and decompress very large amounts of data in multiple formats and use cases.

@@ -4,24 +4,31 @@ Parallel Zstandard is a Pigz-like tool for Zstandard.
It provides Zstandard format compatible compression and decompression that is able to utilize multiple cores.
It breaks the input up into equal sized chunks and compresses each chunk independently into a Zstandard frame.
It then concatenates the frames together to produce the final compressed output.
Optionally, with the `-p` option, PZstandard will write a 12 byte header for each frame that is a skippable frame in the Zstandard format, which tells PZstandard the size of the next compressed frame.
When `-p` is specified for compression, PZstandard can decompress the output in parallel.
Pzstandard will write a 12 byte header for each frame that is a skippable frame in the Zstandard format, which tells PZstandard the size of the next compressed frame.
PZstandard supports parallel decompression of files compressed with PZstandard.
When decompressing files compressed with Zstandard, PZstandard does IO in one thread, and decompression in another.
## Usage
PZstandard supports the same command line interface as Zstandard, but also provies the `-p` option to specify the number of threads.
Dictionary mode is not currently supported.
Basic usage
pzstd input-file -o output-file -n num-threads [ -p ] -# # Compression
pzstd -d input-file -o output-file -n num-threads # Decompression
pzstd input-file -o output-file -p num-threads -# # Compression
pzstd -d input-file -o output-file -p num-threads # Decompression
PZstandard also supports piping and fifo pipes
cat input-file | pzstd -n num-threads [ -p ] -# -c > /dev/null
cat input-file | pzstd -p num-threads -# -c > /dev/null
For more options
pzstd --help
PZstandard tries to pick a smart default number of threads if not specified (displayed in `pzstd --help`).
If this number is not suitable, during compilation you can define `PZSTD_NUM_THREADS` to the number of threads you prefer.
## Benchmarks
As a reference, PZstandard and Pigz were compared on an Intel Core i7 @ 3.1 GHz, each using 4 threads, with the [Silesia compression corpus](http://sun.aei.polsl.pl/~sdeor/index.php?page=silesia).

#### The measurement of performace of Zstandard wrapper for zlib
The zstd distribution contains a tool called `zwrapbench` which can measure speed and ratio of zlib, zstd, and the wrapper.
The benchmark is conducted using given filenames or synthetic data if filenames are not provided.
The files are read into memory and joined together.
It makes benchmark more precise as it eliminates I/O overhead.
Many filenames can be supplied as multiple parameters, parameters with wildcards or names of directories can be used as parameters with the -r option.
One can select compression levels starting from `-b` and ending with `-e`. The `-i` parameter selects minimal time used for each of tested levels.
With `-B` option bigger files can be divided into smaller, independently compressed blocks.
The benchmark tool can be compiled with `make zwrapbench` using [zlibWrapper/Makefile](Makefile).
#### Improving speed of streaming compression
During streaming compression the compressor never knows how big is data to compress.
Zstandard compression can be improved by providing size of source data to the compressor. By default streaming compressor assumes that data is bigger than 256 KB but it can hurt compression speed on smaller data.
The zstd wrapper provides the `ZWRAP_setPledgedSrcSize()` function that allows to change a pledged source size for a given compression stream.
The function will change zstd compression parameters what may improve compression speed and/or ratio.
It should be called just after `deflateInit()`or `deflateReset()` and before `deflate()` or `deflateSetDictionary()`. The function is only helpful when data is compressed in blocks. There will be no change in case of `deflateInit()` or `deflateReset()` immediately followed by `deflate(strm, Z_FINISH)`
as this case is automatically detected.
#### Reusing contexts
The ordinary zlib compression of two files/streams allocates two contexts:
- for the 1st file calls `deflateInit`, `deflate`, `...`, `deflate`, `defalateEnd`
- for the 2nd file calls `deflateInit`, `deflate`, `...`, `deflate`, `defalateEnd`
The speed of compression can be improved with reusing a single context with following steps:
- initialize the context with `deflateInit`
- for the 1st file call `deflate`, `...`, `deflate`
- for the 2nd file call `deflateReset`, `deflate`, `...`, `deflate`
- free the context with `deflateEnd`
To check the difference we made experiments using `zwrapbench -ri6b6` with zstd and zlib compression (both at level 6).
The input data was decompressed git repository downloaded from https://github.com/git/git/archive/master.zip which contains 2979 files.
The table below shows that reusing contexts has a minor influence on zlib but it gives improvement for zstd.
In our example (the last 2 lines) it gives 4% better compression speed and 5% better decompression speed.

/* Approach to just fitting a requested compressed size:
fitblk performs three compression passes on a portion of the input
data in order to determine how much of that input will compress to
nearly the requested output block size. The first pass generates
enough deflate blocks to produce output to fill the requested
output size plus a specfied excess amount (see the EXCESS define
below). The last deflate block may go quite a bit past that, but
is discarded. The second pass decompresses and recompresses just
the compressed data that fit in the requested plus excess sized
buffer. The deflate process is terminated after that amount of
input, which is less than the amount consumed on the first pass.
The last deflate block of the result will be of a comparable size
to the final product, so that the header for that deflate block and
the compression ratio for that block will be about the same as in
the final product. The third compression pass decompresses the
result of the second step, but only the compressed data up to the
requested size minus an amount to allow the compressed stream to
complete (see the MARGIN define below). That will result in a
final compressed stream whose length is less than or equal to the
requested size. Assuming sufficient input and a requested size
greater than a few hundred bytes, the shortfall will typically be
less than ten bytes.
If the input is short enough that the first compression completes
before filling the requested output size, then that compressed
stream is return with no recompression.
EXCESS is chosen to be just greater than the shortfall seen in a
two pass approach similar to the above. That shortfall is due to
the last deflate block compressing more efficiently with a smaller
header on the second pass. EXCESS is set to be large enough so
that there is enough uncompressed data for the second pass to fill
out the requested size, and small enough so that the final deflate
block of the second pass will be close in size to the final deflate
block of the third and final pass. MARGIN is chosen to be just
large enough to assure that the final compression has enough room
to complete in all cases.
