buffer: add encoding parameter to fill() #4935
Conversation
Marked as minor, might actually be a major due to the new throw. |

if (str_length == 0) | ||
return; | ||

memcpy(ts_obj_data + start, *str, MIN(str_length, length)); | ||
// Can't use StringBytes::Write() in all cases. For example if attempting | ||

two byte
@jasnell Is that big endian? Looks like the bytes written are reversed. EDIT: yeah, I see now |
I believe so yeah.

val = code; | ||

Do we want to throw if encoding is not a string?

Guess that's easy enough to detect since end
and start
are both coerced if not strings. Since it's new API throwing won't be a breaking change anyway. I'll look at the rest of the Buffer API to see how it's handled there.

Just checked. Seems write()
and others throw for non-falsy values. Which means 0
, NaN
, null
, etc. all get through. That does seem a little strange to me. Will make it throw for all values not undefined
or typeof string
.

@jasnell Haha! Fifth time's the charm. Everything is passing and comments have been addressed. Mind taking another look? |

Can now call fill() using following parameters if value is a String: fill(string[, start[, end]][, encoding]) And with the following if value is a Buffer: fill(buffer[, start[, end]]) The encoding is ignored if value is not a String. All other non-Buffer values are coerced to a uint32. A multibyte strings will simply be copied into the Buffer until the number of bytes run out. Meaning partial strings can be left behind: Buffer(3).fill('\u0222'); // returns: <Buffer c8 a2 c8> In some encoding cases, such as 'hex', fill() will throw if the input string is not valid.

Thanks much for the review. Landed in b55e580. |
woo! next up, the Buffer constructor changes... that should be just about done also |

Uhoh it looks like b55e580 has broken the test suite for Literally every test is failing now 😢 /cc @trevnorris @rvagg @jasnell @indutny @nodejs/streams |
@thealphanerd got some test output we can see for what's actually breaking? we can either remove it off v5 and make a note in the breaking changes of v6 or we could try and fix it in situ |
Here is a gist of the output of npm test for https://gist.github.com/43e0cc7fd601ead3af42 @indutny is digging in right now and seems to think it might be a bug in the test suite. Whatever the case may be we have some sort of odd behavior change |
@thealphanerd If that's the case then it would have been an edge case for value coercion. I'm fine to fix that for backwards compatibility. |
here is a run of citgm testing node-spdy against v5.x |
