BASH PATCH REPORT
=================
Bash-Release: 5.0
Patch-ID: bash50-004
Bug-Reported-by: Daniel Kahn Gillmor <dkg@fifthhorseman.net>
Bug-Reference-ID: <87lg0g8aiw.fsf@fifthhorseman.net>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2019-04/msg00076.html
Bug-Description:
In bash-5.0, the `wait' builtin without arguments waits for all children of the
shell. This includes children it `inherited' at shell invocation time. This
patch modifies the behavior to not wait for these inherited children, some
of which might be long-lived.

Bug-Description:
Bash-5.0 changed the way assignment statements preceding special builtins
and shell functions were handled in posix mode. They automatically created
or modified global variables instead of modifying existing local variables
as in bash-4.4.
The bash-4.4 posix-mode semantics were buggy, and resulted in creating
local variables where they were not intended and modifying global variables
and local variables simultaneously.
The bash-5.0 changes were intended to fix this issue, but did not preserve
enough backwards compatibility. The posix standard also changed what it
required in these cases, so bash-5.0 is not bound by the strict conformance
requirements that existed in previous issues of the standard.
This patch modifies the bash-5.0 posix mode behavior in an effort to restore
some backwards compatibility and rationalize the behavior in the presence of
local variables. It
1. Changes the assignment semantics to be more similar to standalone assignment
statements: assignments preceding a function call or special builtin while
executing in a shell function will modify the value of a local variable
with the same name for the duration of the function's execution;
2. Changes assignments preceding shell function calls or special builtins
from within a shell function to no longer create or modify global variables
in the presence of a local variable with the same name;
3. Assignment statements preceding a shell function call or special builtin
at the global scope continue to modify the (global) calling environment,
but are unaffected by assignments preceding function calls or special
builtins within a function, as described in item 2. This is also similar
to the behavior of a standalone assignment statement.

Bug-Description:
If alias expansion is enabled when processing the command argument to the
`-c' option, an alias is defined in that command, and the command ends with
the invocation of that alias, the shell's command parser can prematurely
terminate before the entire command is executed.
