Patch for TODO item: "allow starting through symlinks called rrdcreate
rrdtune and the like"
I have implemented a generic solution for the symlink TODO item: If
the basename of argv is not "rrdtool" we expect it to be a rrd*
symlink where rrd* is the string "rrd" suffixed by "*", which can be
anything even the empty string. A new argv structure is created based
on the system initiated argv structure. The only difference in the new
argv structure is that argv is rrdtool and argv is the "*"
suffix of the original system argv. This means that we rely on the
existing source code to warn the user if the command in argv is
system argv = "rrdfetch"
argv = "rrdtool"
argv = "fetch"
and all other arguments are copied unmodified to the new argv structure.
I had to modify some parts of the source tree in order to make the cvs
snapshot compile on my Debian workstation. Later I will try to make
the patch work on freebsd to check that everything plays along nicely.
In addition to changes to src/rrd_tool.c, src/rrd_tool.h, configure.ac
and config.h.in I also had to modify Makefile.am because I see that we
different versions of the autotools suite; rrd_restore.c uses the
O_BINARY definition which does not show up on my Linux workstation and
cannot seem to find it in <bits/fcntl.h>
autoconf --version: 2.59
