           Summary: dmd.conf search path dosn't work
           Product: D
           Version: 0.163
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: shro8822 uidaho.edu


from http://www.digitalmars.com/d/dcompiler.html

"dmd will look for the initialization file dmd.conf in the following sequence
of directories:

   1. current working directory
   2. directory specified by the HOME environment variable
   3. directory dmd resides in
   4. /etc/"

However, on Linux, step number three ("directory dmd resides in") doesn't work.
If /etc/dmd.conf is unreadable, dmd wont find /bin/dmd (assuming /bin/dmd is
being called). This also fails if dmd is run by way of a softlink,
/bin/sub/dmd.conf isn't found when the softlink /bin/sub/dmd is run. I haven't
tested this on windows.

This is a killer for having several setups for dmd. Say I want dmd.163 and
dmd.160 on the same box. If this worked, I could install dmd.163 in /bin with
it's dmd.conf and also place a dmd.160 in /bin/160 with a dmd.conf that points
to the correct phobos imports and libs.

This must be fixed before 1.0 because it would prevent dmd 1.0 and dmd 2.0 from
coexisting on the same box. This is blocking a project I am working on right
now so I would lick to see it fixed ASA Practical.

That's very strange, because that's the way I use dmd on Linux.

I tried copying /etc/dmd.conf to /bin/ and renaming the /etc ver 
something else and DMD started complaining about not being able to find

No. I'll recheck the source code. (You can as well!)

I do all my switching in /etc/dmd.conf and recently had some weird 
problems when I tried using Build on Linux.  It turned out that I had an 
old dmd.conf file in /dmd/bin as well, and removing this fixed things. 
So I think the checking of /bin/dmd/dmd.conf may not work correctly.  I 
have /dmd/bin in my path, could it be that the argv[0] doesn't contain a 
fully qualified path name and so the function ends up looking in the 
current directory twice?

Easy enough to check, compile/run this program on your system:



 #include        <stdio.h>
 #include        <assert.h>
 #include        <stdlib.h>
 
 int main(argc,argv)
 int argc;
 char *argv[];
 {       int i;
 
         printf("%d arguments\n",argc);
         for (i = 0; i < argc; i++)
                 printf("arg[%d] = '%s'\n",i,argv[i]);
         assert(argv[argc] == NULL);
         return EXIT_SUCCESS;

I was being lazy and trying to avoid starting my Linux VM :-)  But I 
just wrote an app like the above, compiled it as "app", moved the 
executable to /dmd/bin, and ran it.  As suspected, argv[0] was "app" and 
not "/dmd/bin/app" as the DMD front-end seems to expect.  I also 
couldn't find a built-in way to determine the location of the executing 
process, so it may be that DMD will have to iterate across the PATH list 
as Build does.

I see, that explains why it worked for me (I used direct path names).

The "executable" name can also be a symbolic link.

ln -s /home/frank/dmd/bin/dmd ./lnk
./lnk


Arg 0 show up with "./lnk". So it is necessary to follow those symbolic
links.

In the case of creating a symlink to dmd (or any other application), I'd 
suggest that the directory of the link be used in preference to the 
location of the other end of the link.  Add another check ahead of the 
binaries location:

...

if [ -e dirname($argv0)/dmd.conf ]; then
     return dirname($argv0)/dmd.conf;

elif [ -l $argv0 && -e dirname(readlink($argv0))/dmd.conf ]; then
     return dirname(readlink($argv0));

elif ...

Sorry for the pseudo shell code, but the equivalent c code isn't much 
different.

When argv[0] isn't an absolute path, then isn't the location of the 
executing process file =  CWD ~ argv[0] ?

You will also have to search the path to find it. argv[0] seems to be 
whatever you used to call the program put something on the path and run 
it without a full path you will get the name you typed in


<code name="test.d">
import std.stdio;
void main(char[][] argv){foreach(i,a;argv)writef("%d:>\"%s\"\n",i,a);}
</code>

// put in path at /bin/foo/
$test
0:>"test"

// call directly
$/bin/foo/test
0:>"/bin/foo/test"

// call locally
$./test
0:>"./test"

Seems to be a direct mapping to whater exec was given.

The current (dmd-0.167) search strategy is incorrect.

sample:
/opt/dmd/bin/dmd
/opt/dmd/bin/dmd.conf
/usr/bin/dmd -> /opt/dmd/bin/dmd (symlink)

PATH=/usr/bin/:/usr/local/bin/
HOME=/home/user
CWD=/home/user/project

dmd-0.167 is looking for dmd.conf in the following places:
[1] /home/user/project/dmd.conf (CWD)
[2] /home/user/dmd.conf (HOME)
[3] /usr/bin/dmd.conf (argv0)
[4] /usr/bin/local/dmd.conf (argv0)
[5] /etc/dmd.conf (/etc)

The problem is that [3] and [4] are using PATH instead of argv0.

dmd should - according to the documentation - look for dmd.conf in the
following places:
[1] /home/user/project/dmd.conf (CWD)
[2] /home/user/dmd.conf (HOME)
[3] /opt/dmd/bin/dmd.conf (argv0)
[4] /etc/dmd.conf (/etc)

See http://d.puremagic.com/issues/show_bug.cgi?id=278#c5 for a fix.

         Resolution|                            |FIXED





This bug was introduced and then fixed within a few hours of the release.  The
1.022 and 2.005 zip files were updated to contain the fix without a new release
and without an announcement.

Marking this bug fixed.  Please re-download if you were unlucky enough to get
the buggy version.   The corrected 2.005 shows version 2.005.1 in the output of
just 'dmd'.  The 1.022 version doesn't identify itself differently (whoops, bad
Walter).

The 1.002 version can be identified by, well, it working correctly, and:

            filesize   md5sum
dmd         1015780    4ffc48d69a3687339720adc4ef9f5c03
dmd.exe     1068060    2ce1fb3f5f9e65aa457622136efb9d2c

If this is fixed, it should be closed.

I'm closing this bug.  Please re-open with specifics if there's still a problem
that anyone can find with config file locating.  If you have a problem, please
give details about:

  1) where you have dmd.conf/sc.ini files
  2) where you have dmd executables
  3) what your PATH env var is set to
  4) exactly how you executed dmd
  5) which conf file was used in case you suggest that it should have used a
different one

Thanks,
Brad
