Report and fix from Tom Tromey <tom@tromey.com> + + 1/26 + ---- +lib/readline/callback.c + - rl_callback_read_char: make sure rl_linefunc is non-NULL before + calling through the pointer.

Bug reported by Matthias Klose <doko@debian.org>, pointer + to root cause from Koichi Murase <myoga.murase@gmail.com> + +lib/glob/glob.c + - skipname,wskipname: put in some additional checks for `.' to ensure + that we don't get false positives (or incomplete tests) that can + affect the results of extglob patterns. Reported by + gregrwm <rhn-users@greatlakedata.com> + + 1/27 + ---- +lib/glob/glob.c + - extglob_skipname,wextglob_skipname: fixed an off-by-one error (SE + was being set to one character before the end of the pattern string, + not the null character at the end of the pattern string like other + callers of glob_patscan) that caused the last character of the last + subpattern to be cut off when calling skipname + - extglob_skipname,wextglob_skipname: some cleanups so the code is + closer to identical for the single-byte and wide character versions + + 2/1 + --- +execute_cmd.c + - execute_simple_command: in posix mode, if we have a variable + assignment error while assigning into the temporary environment (e.g., + assigning to a readonly variable), a non-interactive shell running a + special builtin exits; a non-interactive shell running anything else + jumps back to the top level.

Restore the alias after the compound assignment is parsed. + Reported back in 11/2020 by Alex fxmbsw7 Ratchev <fxmbsw7@gmail.com> + + 2/4 + --- +lib/readline/histexpand.c + - history_expand_internal: when calling the history_inhibit_expansion + function, make sure to call it using the string as we've expanded it + to that point (RESULT), adding the expansion and next characters + temporarily, since we make expansion decisions based on what we've + accumulated, not what we started with. This makes things like + echo abc!$!$ work, where before the second `!' inhibited expansion + because bash_history_inhibit_expansion mistakenly took it as the + second character in a `$!' word expansion.
