`getcwd(3)' returns a NULL pointer when it fails, and a pointer to the buffer
when it succeeds. The array of characters (allocated on the stack) is not NULL,
so it cannot be used to check if `getcwd(3)' succeeded. Use the pointer
returned by `getcwd(3)' to check success.
This make it easier to manage separate compilation units (static functions and
global variables, local type definitions, etc.)
The generated header file `functions.h' caused a circular dependency problem;
it wasn't updated automatically when changes were made to the sources (e.g.
new function definition). The sources can't be in the dependency list of
`functions.h' in the Makefile, because `functions.h' is in the dependency list
of each source file. GNU make is able to ignore the circular dependency but not
BSD make.
At any rate, keeping the prototype list up-to-date is easy, because the
compiler will complain if a function is used in a compilation unit but defined
in an other one.
It also makes static analysis easier out of the box.
When a gopherer comes in contact with a user listing, the current
order is pretty much useless (by UID). It makes much more sense
to sort by the date modified.
Closes#62
Before it only appeared in syslog. Make the error more obvious to
the admin, so that it appears on the page as well, and helps with
debugging.
Closes#32.
Yes, I am still alive, have just been busy.
