srcSize is read and provided at each file, not at resource creation.
This used to be useful with older API, because it could not re-adapt parameters between sessions.
At some point, it will be better to remove the old code, and only keep the new_api.
It works fine by now.
fixes#874 :
when a frame is not properly terminated by a "last block" signal,
zstd -d used to detect it immediately and error out.
This version will decode and flush the last block, and only then issue an error.
* Maximum window size in 32-bit mode is 1GB, since allocations for 2GB fail
on my Mac.
* Maximum window size in 64-bit mode is 2GB, since that is the largest
power of 2 that works with the overflow prevention.
* Allow `--long=windowLog` to set the window log, along with
`--zstd=wlog=#`. These options also set the window size during
decompression, but don't override `--memory=#` if it is set.
* Present a helpful error message when the window size is too large during
decompression.
* The long range matcher defaults to a hash log 7 less than the window log,
which keeps it at 20 for window log 27.
* Keep the default long range matcher window size and the default maximum
window size at 27 for the API and CLI.
* Add tests that use the maximum window size and hash size for compression
and decompression.
Simple makefile change + quick typename change
Test:
make clean
make
# successfully produces binary without lz4 support
make clean
# with flags to pick up my lz4 build
make MOREFLAGS="-L/home/felixh/prog/lz4/lib -I/home/felixh/prog/lz4/lib"
# successfully produces binary with lz4 support
echo "TEST TEST TEST THIS IS A TEST STRING PLEASE TEST THIS PLEASE OK THANK YOU" | \
./lz4/lz4 | \
LD_LIBRARY_PATH=/home/felixh/prog/lz4/lib ./zstd/zstd -d
# successfully prints TEST TEST TEST THIS IS A TEST STRING PLEASE TEST THIS PLEASE OK THANK YOU
file-information is dependent on decompression functions.
it should only be enabled when ZSTD_NODECOMPRESS is not set.
also : added zstd-compress compilation test into `make shortest`
