Queries and data + are parsed as UTF-8, so extended characters can be directly used. + Numeric character escapes can go up to \x10FFF. (More limited on + platforms where wchar_t is 16 bit). Regular expressions support + extended characters, directly or through escapes. Regex character set + matches can use full Unicode range. New test case 005 exercises + some of these features over Japanese text. + + Failed exit status of pipes, and file close errors are exceptions now. + + Bug fixed in regex character classes. + + Fixed off-by-one error in lazy string implementation, which broke + some uses of the @(freeform) directive. + + Fixed all instances of gc bug 28086: objects being prematurely + reclaimed. This showed up when compiling for profiling (gcc -pg). + + The --cc argument of the configure script works properly now. + + Numbers and characters are unboxed types now, encoded directly in + the (obj_t *) value. Lowest two bits of (obj_t *) are a tag + distinguishing characters, integers and pointers. The program + performs better from not having to cons memory when operating + on numbers and characters. + + Discovered bug in glibc: getwc function segfaults when applied to + stream returned by popen. Worked around this bug. Bug is filed + as 10958 in glibc bugzilla. + + Internals: + + Hash tables implemented. Hash tables support weak keys and values. + + * configure, hash.c, lib.c, stream.c, utf8.c: Removed trailing + from some lines. + + * txr.c (version): Bumped to 021. Removed trailing whitespace. + + * txr.1: Bumped version to 021. + 2009-11-14 Kaz Kylheku <kkylheku@gmail.com> Provide both char * and unsigned char * interfaces in UTF-8 module. |
