prunsrv.exe fails if filename is less than 4 characters long
------------------------------------------------------------
Key: DAEMON-85
URL: http://issues.apache.org/jira/browse/DAEMON-85
Project: Commons Daemon
Type: Bug
Versions: 1.0.1 Final
Environment: Win2k
Reporter: Michael Goddard
In cmdline.c, function apxCmdlineParse the following three lines check if the
length if arg[0] is greater than the length of .EXE.
However on windows, exe's can be executed without their .exe prefix. This
means, if prunsrv.exe is renamed to 3 characters or less, the check fails and
command line arguments arn't parsed returning an error. I could not figure out
why the check is there, it seems to serve no purpose and if commented out the
bug goes away.
Code at fault:
l = lstrlenW(_st_sys_argvw[0]);
if (l < EXE_SUFFIXLEN)
return NULL;
To reproduce:
1. Rename prunsrv.exe to say abc.exe
2. Execute the service executable directly as 'abc' in the current folder, do
not type 'abc.exe'. (useful to use when debugging the app)
3. See it fail to parse command line arguments
To solve:
Remove offending lines. Perhaps check if arg[0] length is less than or equal to
0 instead of 4, which would be a valid case to fail in.
