New version available. As I don't want to spam the list with various
versions until I get it right eventually, you can get it from
http://members.aon.at/pivot/pg/fixchar20021010.tgz if you are
interested.
What's new:
. README updated (per Shridhar's suggestion)
. doesn't crash on NULL (p. Tom)
. version-1 calling conventions (p. Tom)
. isCachable (p. Tom)
. works for 7.2 (as delivered) and for 7.3 (make for73)
Shridhar, you were concerned about signed/unsigned chars; looking at
the code I can not see how this is a problem. So no change in this
regard.
Thanks for your comments. Have fun!
Servus
Manfred

Well, this is not related to postgresql exactly but to summerise the problem,
with libc patch PHCO_19090 or compatible upwards, on HP-UX11, isspace does not
work correctly if input value is >127. Can cause lot of problem for an external
app. It works fine with unsigned char
Does not make a difference from postgrersql point of view but would break non-
english locale if they want to use this fix under some situation.
But I agree, unless somebody reports it, no point fixing it and we know the fix
anyway..
Bye
Shridhar
