Description Tom Tromey 2008-04-28 14:04:02 UTC
I wanted to try a completion test case in fhpd, so I tried running
it on a just-build gdb I have.  To my surprise it picked up the system
gdb instead:

opsy. fhpd ./gdb
[0.0] Loaded executable file: /usr/bin/gdb

If the argument to fhpd has a directory separator, I think it should
be searched for in '.' first.  Note that this is different from 
prepending '.' to PATH... I think fhpd should mimic the shell's lookup

Consider relative paths when searching for executable.
* SysRoot.java (findExe): Consider relative paths.

Comment 3 Tom Tromey 2008-04-30 18:52:47 UTC
It still seems a little wrong to me.

For example, if 'gdb' is a directory:

opsy. fhpd gdb
Error: gdb is a directory
opsy. fhpd ./gdb
Error: ./gdb is a directory

IMO, the first one should pick gdb from $PATH.
The second one should continue to fail as it does now.

That is, mimic shell behavior.

Follow Unix ./executable convention.
* SysRoot.java (findExe): Follow Unix ./executable convention.
* TestSysRoot.java (testExePath): New
