[Bug 18154] New: cmd.exe: failure to handle file extension association

http://bugs.winehq.org/show_bug.cgi?id=18154

Summary: cmd.exe: failure to handle file extension association
           Product: Wine
           Version: 1.1.19
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P4
         Component: programs
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

cmd.exe doesn't handle extension association.

Test case:
Install ActivePerl, create a dummy perl script test.pl and run
    wine cmd /c test.pl
cmd.exe will try to run test.pl as Unix binary
    trace:process:CreateProcessW starting L"C:\\test.pl" as Unix binary
and (probably) fail instead of running Perl.exe as the Windows XP command
    cmd /c perl.pl

Source code analysis:
The function programs/cmd/wcmdmain.c:WCMD_run_program calls FindExecutable
but mostly ignores the result. This looks like an unfinished work.

Remark:
Theoretically, some program could rely on the association. As long as such
program is not known, this is a low priority issue. Users should prefer
the explicit command
    wine perl test.pl
(or "wine start /W test.pl" if they want a new console).
