/* $Id: install.c,v 1.179 2008-06-20 23:48:01 megastep Exp $ */
/* Modifications by Borland/Inprise Corp.:
04/10/2000: Added code to expand ~ in a default path immediately after
XML is loaded
04/12/2000: Modifed run_script function to put the full pathname of the
script into the temp script file. In some cases, setup was
having trouble finding the script.
04/21/2000: Setup could not launch the game if the bin dir isn't in the
user's path. Changed launch_game so it references the full
pathname for the symlink.
05/17/2000: Modified create_install function to allow two new parameters:
install_path and binary_path. These may have been passed in
using the -i and -b command line parameters. If so, then the
info->install_path or info->symlinks_path will be set using
the values from the command line.
05/20/2000: Modified generate_uninstall so that it will add "rpm -e ..."
to the uninstall script for any RPM files that have their
autoremove flag set. Modified the rpm_elem structure to include
an new element for the autoremove flag. This is set on the
"files" tag, similar to the "relocate" flag. See copy.c for
details.
05/24/2000: Modified generate_uninstall and uninstall functions to support
two new options on the <install> tag:
<install preuninstall="script_filename"
postuninstall="script_filename" ... >
This allows extra cleanup to be done before and after the files
are removed. The contents of the script specified by the
preuninstall option is added to the beginning of the uninstall
script, before the file list and before any RPM uninstall
scripts. The contents of the script specified by the
postuninstall option is added to the end of the uninstall script
after any RPM uninstall scripts. Note that the pre- and post-
uninstall scripts are not installed. Their contents are streamed
into the uninstall script. Also note that these scripts should
be executable as stand-alone scripts (they should have the
#!/bin/sh at the beginning) because in the event the install is
aborted, these scripts will be run individually at the beginning
and end of the cleanup process.
Modified generate_uninstall to add environment settings to the
very beginning of the uninstall script. This allows the
uninstall script to use these variables: $SETUP_PRODUCTNAME,
$SETUP_PRODUCTVER, $SETUP_INSTALLPATH, $SETUP_SYMLINKSPATH,
and $SETUP_CDROMPATH
