ash: fix shell options

2020-07-07T16:02:58+00:00

The Windows-specific shell options winxp, noconsole and nocaseglob have had the wrong indices in optlist since the merge with upstream BusyBox in commit 517cf74f6.

ash: improve handling of UNC paths

2020-06-30T14:52:54+00:00

Be more strict about identifying UNC paths in unc_root_len(). In updatepwd() in ash: - Skip duplicate leading slashes unless the directory is a UNC path. - Rewrite detection and handling of the five possible types of path. This improves cases like 'cd ///' and 'cd /xyz' when the current directory is a UNC path. See GitHub issue #192.

ash: avoid duplicated slashes in output of type/command builtins

2020-06-29T10:46:43+00:00

Microsoft developers have a penchant for adding trailing slashes to entries in PATH: C:/Windows/System32/WindowsPowerShell/v1.0/ C:/Windows/System32/OpenSSH/ The 'type' and 'command -v' shell builtins return paths with duplicated slashes for executables in those directories. See GitHub issue #191. Bonus fixes: - handle backslashes as well as slashes in concat_path_file() - convert backslashes to slashes in the output of 'type', 'command -v'

ash: skip NULL argv during forkshell

2020-06-21T11:57:12+00:00

Alter argv_size()/argv_copy() to omit argv from the forkshell block if it's NULL. Improve forkshell debug code to properly account for parts of funcblock which aren't being used.

ash: changes to ctrl-c handling

2020-06-20T11:13:57+00:00

Make ctrl-c handling more like Unix. Remove the hSIGINT event and the code in waitpid_child() to catch it. Add a call to raise_interrupt() in ctrl_handler(). Prior to these changes interrupts in a child shell weren't properly handled. In release FRP-3466-g53c09d0e1 interrupting a sleep in a child shell results in both shells competing for input: ~ $ sh ~ $ sleep 10 ^C^C ~ $ ~ $ pwd sh: w: not found ~ $ sh: pd: not found ~ $ With recent changes: ~ $ sh ~ $ sleep 10 ^C ~ $ echo $? 130 ~ $ exit ^C ~ $ echo $? 130 ~ $ The error return from the parent shell is due to the lack of job control. Upstream BusyBox ash and dash both do the same when job control is disabled.
