churro morales commented on HADOOP-13578:
-----------------------------------------
[~jlowe] in regards to your previous comment in regards to not returning after
throwing. I can make the following change:
{code}
size_t size = dlsym_ZSTD_compressStream(stream, &output, &input);
if (dlsym_ZSTD_isError(size)) {
THROW(env, "java/lang/InternalError", dlsym_ZSTD_getErrorName(size));
return (jint) 0;
}
if (finish && input.pos == input.size) {
// end the stream, flush and write the frame epilogue
size = dlsym_ZSTD_endStream(stream, &output);
if (!size) {
(*env)->SetBooleanField(env, this, ZStandardCompressor_finished,
JNI_TRUE);
}
}
else {
// need to flush the output buffer
// this also updates the output buffer position.
size = dlsym_ZSTD_flushStream(stream, &output);
}
if (dlsym_ZSTD_isError(size)) {
THROW(env, "java/lang/InternalError", dlsym_ZSTD_getErrorName(size));
return (jint) 0;
}
{code}
If you are okay with this I can put up a new patch containing this fix.
