* Faster sv_utf8_upgrade()karl williamson2009-01-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider what currently happens when the tokenizer is scanning a string. It looks through it byte-by-byte until it finds a character that forces it to decide to go to utf8. It then calls sv_utf8_upgrade() with the portion of the string scanned so far. sv_utf8_upgrade() starts over from the beginning, and scans the string byte-by-byte until it finds a character that varies between non-utf8 and utf8. It then calls bytes_to_utf8(). bytes_to_utf8() allocates a new string that can handle the worst case expansion, 2n+1, of the entire string, and starts over from the beginning, and scans the input string byte-by-byte copying and converting each character to the output string as it goes. It doesn't return the size of the new string, so sv_utf8_upgrade() assumes it is only as big as what actually got converted, throwing away knowledge of any spare. It then returns to the tokenizer, which immediately does a grow to get space for the unparsed input. This is likely to cause a new string to be allocated and copied from the one we had just created, even if that string in actuality had enough space in it. Thus, the invariant head portion of the string is scanned 3 times, and probably 2 strings will be allocated and copied. My solution to cutting this down is to do several things. First, I added an extra flag for sv_utf8_upgrade that says don't bother to check if the string needs to be converted to utf8, just assume it does. This eliminates one of the passes. I also added a new parameter to sv_utf8_upgrade that says when you return, I want this much unused space in the string. That eliminates the extra grow. This was all done by renaming the current work-horse function from sv_utf8_upgrade_flags to be sv_utf8_upgrade_flags_grow() and making the current function name be a macro which calls the revised one with a 0 grow parameter. I also improved the internal efficiency of sv_utf8_upgrade so that when it does scan the string, it doesn't call bytes_to_utf8, but does the conversion itself, using a fast memory copy instead of the byte-oriented one for the invariant header, and it uses that header to get a better estimate of the needed size of the new string, and it doesn't throw away the knowledge of the allocated size. And, if it is clear without scanning the whole string that the conversion will fit in the already allocated string, it just uses that instead of allocating and copying a new one, using the algorithm I copied from the tokenizer. (In this case it does have to finish scanning the whole string to get the correct size.) The comments have details. It still is byte-oriented. Vectorization et. al. could yield performance improvements. One idea for that is in the comments. The patch also includes a new synonym I created which is a more accurate name than NATIVE_TO_ASCII.

This allows SvOOK() to co-exist with SvIOK_on(), which means all the calls to SvOOK_off() [with the possibility of a call to sv_backoff()] in SvIOK_on() can be removed.
