even in case of failure.

dab3590fce Export deprecated symbols declared in lz4hc.h 
Commit 25b2435885 exported deprecated
symbols declared in lz4.h by marking all LZ4_DEPRECATED functions with
LZ4LIB_API attribute.  This change does the same with functions declared
in lz4hc.h file, thus extending the export to lz4hc.h.

As result, the following 17 deprecated functions are exported again:

LZ4_compressHC
LZ4_compressHC2
LZ4_compressHC2_continue
LZ4_compressHC2_limitedOutput
LZ4_compressHC2_limitedOutput_continue
LZ4_compressHC2_limitedOutput_withStateHC
LZ4_compressHC2_withStateHC
LZ4_compressHC_continue
LZ4_compressHC_limitedOutput
LZ4_compressHC_limitedOutput_continue
LZ4_compressHC_limitedOutput_withStateHC
LZ4_compressHC_withStateHC
LZ4_createHC
LZ4_freeHC
LZ4_resetStreamStateHC
LZ4_sizeofStreamStateHC
LZ4_slideInputBufferHC

aae447fffd LZ4_compress_HC_continue_destSize() works as intended up to level 10 
It's incompatible with btopt though,
so cLevel >= 11 feature much reduced performance (degraded mode)

cd35f0d98c LZ4_compress_HC_destSize() uses LZ4HC_compress_generic() code path 
Limits compression level to 10,
to remain compatible with Hash Chain.

Export only those symbols that are part of public API

883ebdcee0 Export only those symbols that are part of public API 
Specify -fvisibility=hidden parameter when linking the shared library
using -fPIC, assuming that gcc >= 4 is used.

This change results to unexporting of the following 42 functions:

25b2435885 Export deprecated symbols 
Deprecated symbols are still a part of ABI and have to be exported,
so mark them with LZ4LIB_API attribute.
 2017-03-10 23:35:30 +00:00
Dmitry V. Levin
7aeecbff71 Explicitly set visibility of public API functions when gcc is used 
Windows builds already limit exporting of functions to those marked
with LZ4LIB_API tag.  The same behaviour could be achieved on other
platforms when a relatively fresh gcc is used.

This change assigns public visibility to all symbols marked with
LZ4LIB_API tag.  When the library is built in -fvisibility=hidden
mode, only these marked symbols will be exported.

See also: https://github.com/Cyan4973/lz4/issues/216#issuecomment-226245432

Deprecated functions aren't LZ4LIB_API targets. Because we don't need to
export deprecated functions from now.

There are same LZ4LIB_API definitions in each header files instead of
including a common header file because LZ4_DEPRECATED is defined so.

dc868cd5b1 Allow for safe in-place decoding 
Add a check to allow safe "in-place" decoding (meaning that the
beginning of the source buffer partially overlaps the end of the
destination buffer). This is usually possible as long as the output
stops at least 15 bytes before the end of the input buffer (7 to account
for the extra spill from LZ4_wildCopy, 4 for a possible block checksum,
and 4 for the terminating block header), but in some pathological edge
cases it could be possible for the output stream to overwrite a byte in
the input stream before it gets decoded. With this patch the decoder
will reliably detect those cases and return a decoding error.
