* random lz4f clarificationsYann Collet2018-05-021-16/+38
| | | | | | | | | | | | | | the initial intention was to update lz4f ring buffer strategy, but lz4f doesn't use ring buffer. Instead, it uses the destination buffer as much as possible, and merely copies just what's required to preserve history into its own buffer, at the end. Pretty efficient. This patch just clarifies a few comments and add some assert(). It's built on top of #528. It also updates doc.

* | lz4_Block_format.md: clarify on short inputs and restrictionsAlexey Tourbin2018-04-241-3/+12
|/ | | | | | | | | | | | | | | | | | | | | | It occurred to me that the formula "The last 5 bytes are always literals", on the list of "assumptions made by the decoder", is remarkably ambiguous. Suppose the decoder is presented with 5 bytes. Are they literals? It may seem that the decoder degenerates to memcpy on short inputs. But of course the answer is no, so the formula needs some clarification. Parsing restrictions should be explained as well, otherwise they look like arbitrary numbers. The 5-byte restriction has been mentioned recently in connection with the shortcut in LZ4_decompress_generic, so I add that. The second restriction is left to be explained by the author. I also took the liberty to explain that empty inputs "are either unrepresentable or can be represented with a null byte". This wording may actually have some merit: it leaves for the implementation, as opposed to the spec, to decide whether the encoder can compress empty inputs, and whether the decoder can produce an empty output (which the implementation should further clarify).

| | | | | | | Someone found it would be a great idea to define there a global variable under the very generic name "index". Cause problem with shadow warnings, so no variable can be named "index" now ... Also : automatically update API manual
