and the previous version, bash-4.0-alpha.

1. Changes to Bash
|
||||
|
||||
a. Fixed a bug that caused failed word expansions to set $? but not
|
||||
PIPESTATUS.
|
||||
|
||||
b. Changed filename completion to quote the tilde in a filename with a
|
||||
leading tilde that exists in the current directory.
|
||||
|
||||
c. Fixed a bug that caused a file descriptor leak when performing
|
||||
redirections attached to a compound command.
|
||||
|
||||
d. Fixed a bug that caused expansions of $@ and $* to not exit the shell if
|
||||
the -u option was enabled and there were no posititional parameters.
|
||||
|
||||
e. Fixed a bug that resulted in bash not terminating immediately if a
|
||||
terminating signal was received while performing output.
|
||||
|
||||
f. Fixed a bug that caused the shell to crash after creating 256 process
|
||||
substitutions during word completion.
|
||||
|
||||
2. Changes to Readline
|
||||
|
||||
a. Fixed a bug that caused redisplay errors when using prompts with invisible
|
||||
characters and numeric arguments to a command in a multibyte locale.
|
||||
|
||||
b. Fixed a bug that caused redisplay errors when using prompts with invisible
|
||||
characters spanning more than two physical screen lines.

34. Bash-4.0 allows the behavior in the previous item to be modified using

the notion of a shell `compatibility level'.

35. Bash-3.2 (patched) and Bash-4.0 fix a bug that leaves the shell in an
|
||||
inconsistent internal state following an assignment error. One of the

changes means that compound commands or { ... } grouping commands are
|
||||
aborted. This is what Posix specifies.
|
||||
|
||||
36. Bash-4.0 now allows process substitution constructs to pass unchanged
|
||||
through brace expansion, so any expansion of the contents will have to be
|
||||
separately specified, and each process subsitution will have to be
|
||||
separately entered.
|
||||
|
||||
37. Bash-4.0 now allows SIGCHLD to interrupt the wait builtin, as Posix
|
||||
specifies, so the SIGCHLD trap is no longer always invoked once per
|
||||
exiting child if you are using `wait' to wait for all children.
|
||||
|
||||
38. Since bash-4.0 now follows Posix rules for finding the closing delimiter
|
||||
of a $() command substitution, it will not behave as previous versions
|
||||
did, but will catch more syntax and parsing errors before spawning a
|
||||
subshell to evaluate the command substitution.
|
||||
|
||||
39. The programmable completion code uses the same set of delimiting characters
|
||||
as readline when breaking the command line into words, rather than the
|
||||
set of shell metacharacters, so programmable completion and readline
|
||||
should be more consistent.
|
||||
|
||||
40. When the read builtin times out, it attempts to assign any input read to
|
||||
specified variables, which also causes variables to be set to the empty
|
||||
string if there is not enough input. Previous versions discarded the
|
||||
characters read.
