system() call does not launch aliases

[oco]

Aliases defined using the alias command can not be run via a system() call.

In the open office build system (OOo4Kids), a shell script define some aliases. If i understand things correctly, those commands are intended to be launch with a perl script (build.pl) that use system(). It does not work under Haiku.

I can workaround the problem with symlinks.

I am not absolutely sure that Haiku should support this. Documents i have found (only a google search) don't describe how system() should work in this case. I don't have a linux box right now to confirm the behavior under Linux. I will do the test next week.

The problem could be reproduced using this c program :

#include <unistd.h>

int main() {

system("ll"); return 0;

}

ll is an alias for "ls -lA" defined by default under Haiku.

This program shows an error :

/bin/sh: ll: command not found

There's a difference between ll and custom build-time aliases.

ll is defined in some system-wide sh file (something like /etc/profile, not sure where it is on Haiku). It relies on sh importing this file whenever it loads (as system loads it)

User-defined aliases, on the other hand, relies on sh inheriting aliases from the parent shell ? or how are they defined and run ? I don't think this makes sense, as user customizations to their system shell may break the openoffice build...

My simple test program has the same behavior on my Ubuntu 11.04 as Haiku. There is probably something i have overlook in the OOo4Kids build system. I will ask them how alias commands are supposed to be launched.

Move POSIX compatibility related tickets out of R1 milestone (FutureHaiku/Features).

[korli]

same behavior on ubuntu.

Remove milestone for tickets with status = closed and resolution != fixed
