Thread: Antw: Re: Patch for NetWare support

Hi Bruce,

at the moment NetWare doesn't have symbolic links so it's the only
chance for me to decide between postmaster, bootstrap or normal
interactive backend.

Sorry for that. Novell will add symbolic and hard links to the file
system
but they don't have it yet. As soon as they have links we can remove
the
code.

I wish we didn't have to add this part of the patch to main.c:

+       /*
+        * If the first argument is "-post", then invoke postmaster
mode. Note
+        * we remove "-post" from the arguments passed on to
BootstrapMain.
+     * This is added for one reasons: NetWare doesn't have symbolic
links
+     * right. ((
+        */
+       if (argc > 1 && strcmp(new_argv[1], "-post") == 0)
+               exit(PostmasterMain(argc - 1, new_argv + 1));

Do we have to document this, but only for Netware?  Yuck.

Does it have hard links?  Does it have 'ln' at all?  Otherwise we should
define $(LN_S) to 'cp' and just make a copy.  That way we avoid patching
up the code.

Doesn't the cp trick invalidate the fork-no-exec performance
optimization?

No.
