LzmaDec_TryDummy() was called before to exclude LITERAL and MATCH-REP cases.
So first symbol can be only MATCH-NON-REP. And if that MATCH-NON-REP symbol
is not END_OF_PAYALOAD_MARKER, then function returns error code.
is not END_OF_PAYALOAD_MARKER, then the function doesn't write any byte to dictionary,
the function returns SZ_OK, and the caller can use (p->remainLen) and (p->reps[0]) later.
}
Processing:
first LZMA symbol will be decoded in any case
All checks for limits are at the end of main loop,
It will decode new LZMA-symbols while (p->buf < bufLimit && dicPos < limit),
The first LZMA symbol will be decoded in any case.
All main checks for limits are at the end of main loop,
It decodes additional LZMA-symbols while (p->buf < bufLimit && dicPos < limit),
RangeCoder is still without last normalization when (p->buf < bufLimit) is being checked.
But if (p->buf < bufLimit), the caller provided at least (LZMA_REQUIRED_INPUT_MAX + 1) bytes for
next iteration before limit (bufLimit + LZMA_REQUIRED_INPUT_MAX),
that is enough for worst case LZMA symbol with one additional RangeCoder normalization for one bit.
So that function never reads bufLimit [LZMA_REQUIRED_INPUT_MAX] byte.
Out:
RangeCoder is normalized
Result:
SZ_OK - OK
SZ_ERROR_DATA - Error
p->remainLen:
< kMatchSpecLenStart : normal remain

p->remainLen:
< kMatchSpecLenStart : the number of bytes to be copied with (p->reps[0]) offset

SZ_ERROR_DATA - error, when the MATCH-Symbol refers out of dictionary

LZMA supports optional end_marker.
So the decoder can lookahead for one additional LZMA-Symbol to check end_marker.
That additional LZMA-Symbol can require up to LZMA_REQUIRED_INPUT_MAX bytes in input stream.
When the decoder reaches dicLimit, it looks (finishMode) parameter:
if (finishMode == LZMA_FINISH_ANY), the decoder doesn't lookahead
if (finishMode != LZMA_FINISH_ANY), the decoder lookahead, if end_marker is possible for current position
When the decoder lookahead, and the lookahead symbol is not end_marker, we have two ways:
1) Strict mode (default) : the decoder returns SZ_ERROR_DATA.
2) The relaxed mode (alternative mode) : we could return SZ_OK, and the caller
must check (status) value. The caller can show the error,
if the end of stream is expected, and the (status) is noit
LZMA_STATUS_FINISHED_WITH_MARK or LZMA_STATUS_MAYBE_FINISHED_WITHOUT_MARK.
