There was a problem hiding this comment.
Line 406 is incorrect. It should be:
byteswritten += written;Chuck

Thanks for your PR, but the core and libraries have changed enough that this PR now has a merge conflict. Could you merge it manually with the latest core, so we can consider it for future releases? |

Thats a shame - as this code probably goes wrong in a second way - on short writes too.

Ok - so basically all we need to do is check the return of the write()s and
bytes_written = 0;
while(bytes_writen < len) {
r = write(buff + bytes_written, len - bytes_written);
if (r == 0)
return error that connection is lost
bytes_written += r;
}
And as far as I know there is no r = -1 with various ERRNO sort of things that need to be retried (EAGAIN, EINTR, BSD style). As ‘r’ seems to be a sssize_t.

This is all @dirkx , whose PR unfortunately got borked when we were trying to update it to the new format. As @dirkx said: When sending POST responses of well over a K - _write() may not sent it all. Make sure we do -- but cap the individual writes - as somehow large 2-3k blobs seem to cause instability (on my 12F units). Supercedes esp8266#2528
