2017-05-26When running rc on the following script, rc crashes.Drazen Borkovic
fn f1 { v=x { }} fn f2 { f1 1; f1 2 } f2 whatis Valgrind stack: ==10068== Invalid read of size 8 ==10068== at 0x40EFB1: varlookup (var.c:84) ==10068== by 0x407B04: whatare_all_vars (hash.c:311) ==10068== by 0x401E60: b_whatis (builtins.c:323) ==10068== by 0x402E32: exec (exec.c:92) ==10068== by 0x40F997: walk (walk.c:39) The reason is that vp[h].p is freed in delete_var(), but the pointer is kept. Later the pointer is found to be non-null and dereferenced causing the crash.

2017-04-17Parse equals sign as keywordBert Münnich
The parser treats unexpected keyword tokens (eg. if, while, ~) as literals and not as syntax errors. It does not do this for the equals sign, but it could, as it only has a special meaning at the beginning of a command, much like the keywords. Doing this allows one to write commands like this: dd if'='/dev/zero of'='data bs'='1024 count'='1 without the quotes around the equals signs. All shells from the Bourne family do this. For this to work, the lexer must not automatically terminate words at equals signs, instead it has to generate a free caret around it like for the twiddle and other such special characters. In the parser's grammar we need to get rid of the left recursion in the rules for 'simple' to turn the reduce/reduce conflict at 'first' on '=' (empty -> 'optcaret' or 'first' -> 'simple') into a shift/reduce conflict, which then can be solved with precedence/associativity so that the reduction of the empty 'optcaret' wins over shifting '='.

Restore signal handlers when catching signals in edit_alloc()
2015-11-28Restore signal handlers when catching signals in edit_alloc()Bert Münnich
edit_catcher() performs a longjmp via rc_raise() to the matching setjmp in doit(). The latter does the same as before, so that edit_alloc() gets called again, but this time the installation of the signal handlers trashes the old handlers saved in the last call. Once readline() returns normally to edit_alloc() the wrong signal handlers get restored. The simplified call hierarchy looks like this: doit(); sigsetjmp(); edit_alloc(); oldint = sys_signal(SIGINT, edit_catcher); readline(); SIGINT -> edit_catcher(); siglongjmp(); sys_signal(SIGINT, oldint); Restoring the old signal handlers in edit_catcher() solves this.
