Tom Lane	e04fa58dcd	Fix unportable usages of tolower(). On signed-char machines, it is necessary ... to explicitly cast the output back to char before comparing it to a char value, else we get the wrong result for high-bit-set characters. Found by Rolf Jentsch. Also, fix several places where <ctype.h> functions were being called without casting the argument to unsigned char; this is likewise unportable, but we keep making that mistake :-(. These found by buildfarm member salamander, which I will desperately miss if it ever goes belly-up.	18 years ago

Andrew Dunstan	e152893305	Go back to using a separate method for doing ILIKE for single byte ... character encodings that doesn't involve calling lower(). This should cure the performance regression in this case complained of by Guillaume Smet. It still leaves the horrid performance for multi-byte encodings introduced in 8.2, but there's no obvious solution for that in sight.	19 years ago
Tom Lane	7583f9a7ca	Fix regex, LIKE, and some other second-rank text-manipulation functions ... to not cause needless copying of text datums that have 1-byte headers. Greg Stark, in response to performance gripe from Guillaume Smet and ITAGAKI Takahiro.	19 years ago
Andrew Dunstan	15f8202c20	Improve efficiency of LIKE/ILIKE code, especially for multi-byte charsets, ... and most especially for UTF8. Remove unnecessary special cases for bytea processing and single-byte charset ILIKE. a ILIKE b is now processed as lower(a) LIKE lower(b) in all cases. The code is now considerably simpler. All comparisons are now performed byte-wise, and the text and pattern are also advanced byte-wise where it is safe to do so - essentially where a wildcard is not being matched. Andrew Dunstan, from an original patch by ITAGAKI Takahiro, with ideas from Tom Lane and Mark Mielke.	19 years ago
Tom Lane	234a02b2a8	Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len). ... Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with VARSIZE and VARDATA, and as a consequence almost no code was using the longer names. Rename the length fields of struct varlena and various derived structures to catch anyplace that was accessing them directly; and clean up various places so caught. In itself this patch doesn't change any behavior at all, but it is necessary infrastructure if we hope to play any games with the representation of varlena headers.
