This document details the changes between this version, bash-5.2-rc1, and
|
||||
the previous version, bash-5.2-beta.
|
||||
|
||||
1. Changes to Bash
|
||||
|
||||
a. Changes to `wait -p' and how it sets the variable name in the presence of
|
||||
valid and invalid PID arguments.
|
||||
|
||||
b. Fixed a bug that caused compgen to dump core if the completion engine was
|
||||
not initialized.
|
||||
|
||||
c. Fixed a memory leak in the variable name programmable completion code.
|
||||
|
||||
d. Here-documents and here-strings use tempfiles if the shell compatibility
|
||||
level is 50 or lower.
|
||||
|
||||
e. Non-interactive shells exit on a syntax error encountered while parsing a
|
||||
command substitution.
|
||||
|
||||
f. Fixed a bug with inherited parser state while parsing a command substitution.
|
||||
|
||||
g. Fixed a bug that caused the shell not to check for terminating signals
|
||||
after executing the command_string supplied with `-c' and before executing
|
||||
the exit trap.
|
||||
|
||||
h. Changes to avoid a make race condition while generating builtins.c.
|
||||
|
||||
i. Make it explicit that BASH_REMATCH is always a global variable, and that
|
||||
local copies are (currently) ignored.
|
||||
|
||||
j. Fixed a bug that caused an ambiguous redirection (>&word) to be printed
|
||||
incorrectly (>&word) if no file descriptor was supplied.
|
||||
|
||||
2. Changes to Readline
|
||||
|
||||
a. Fixed a bug that caused rl_eof_found to be set prematurely while reading a
|
||||
multi-character key sequence in callback mode.
|
||||
|
||||
3. New Features in Bash
|
||||
|
||||
a. In posix mode, the `printf' builtin checks for the `L' length modifier and
|
||||
uses long double for floating point conversion specifiers if it's present,
|
||||
double otherwise.
|
||||
|
||||
b. The `globbing' completion code now takes the `globstar' option into account.
|
||||
|
||||
c. `suspend -f' now forces the shell to suspend even if job control is not
|
||||
currently enabled.
