1) The script now issues an error when an option has been specified with no value
following it. For example, ydbinstall.sh --installdir --utf8 default. In this case,
--installdir needs to be followed by a directory name but that was missed out in the
specification. Previously, --utf8 (because that parameter immediately follows --installdir
in the command line) was assumed to be the directory where the install was desired and this
led to confusing results.
2) If a relative path is specified as the install directory name, the script now creates a
subdirectory under the current directory at the time when the script was invoked and installs
YottaDB there. Previously, it used to install YottaDB in a subdirectory under /tmp, later
remove the entire directory and yet confusingly display a message indicating the install
was successful.
3) If the configure script (that ydbinstall internally invokes) fails in determining the effective
userid using the geteuid executable (say because libelf.so is not found etc.), it used to exit
with an exit status of 0 back to its caller ydbinstall. This caused the latter to incorrectly
conclude the install is successful when actually it was not. This is now fixed by exiting with
a non-zero status at that point.
4) While fixing (3), it was determined that the effective user id check is done by both ydbinstall
and configure separately. The former uses "id -un" whereas the latter uses "geteuid" executable.
The sole purpose of the geteuid executable was this use in configure. This is therefore now
replaced with a "id -un" check just like in ydbinstall. And as a result geteuid is now removed
from the code base and YottaDB distribution.
5) While analyzing (3), it was helpful to enable verbose mode inside the configure script when
invoked from ydbinstall. Since all the verbose output goes to a temporary file (configure.out
and configure.err) and is not seen by the user in case of success, but is very helpful in
case of errors, this change ("sh -x configure.sh" invocation) is therefore retained permanently.
