| | | | | | | | | | Tweak code to avoid contamination of the POSIX build. There weren't any adverse effects, but better safe than sorry.
* | ash: tidy code, no functional changeRon Yorston2021-07-121-24/+14
| | | | | | | | | | | | If we know fs_size is nonzero there's no point in having SAVE_PTR2 and SAVE_PTR3 macros. The code is slightly tidier if we only use SAVE_PTR.

| | | | | | | | | | | | | | | | | | | | Interrupting a loop like this: while true; do echo hello; done with ctrl-c caused the shell to exit. Turning off interrupts around the calls to echo_main() and printf_main() improves matters, though isn't a complete cure.

| * shell: also do word splitting when -d DELIM is usedEicke Herbertz2021-06-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original commit 3bef5d89b0 introduced an additional check for an unset `opt_d` before doing word splitting. I'm unsure why it's there in the first place, but the commit message also describes a different behaviour than what -d actually does in bash, while the code mostly does the right thing. `opt_d` sets the line delimiter for read to stop reading and should not affect word splitting.

* | ash: correctly identify applet in getopt() error messagesRon Yorston2021-03-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | With the default configuration most applets are run from the shell via run_noexec_applet_and_exit(). If the applet runs getopt() and an error is detected the message takes the form: sh: unknown option -- q This happens because mingw-w64's implementation of getopt() uses the global variable __argv[0] as the name of the program. Avoid the misleading message by setting __argv[0] as appropriate.
