Loki Patch Tools 1.0
Introduction
============
This is a set of tools written by Loki Software, Inc., designed to
create a set of binary patches that can be easily used either by
themselves or in conjunction with the Loki Update Tool.
Licensing
=========
This update tool is available for use under the GNU General Public License.
How To Create A Patch
=====================
* Create a directory for your patch source files:
mkdir upgrade
cd upgrade
* Create binary and data directories for the original files. e.g:
mkdir bin-1.54a-x86 data-1.54a
* Create binary and data directories for the new files, e.g:
mkdir bin-1.54b-x86 data-1.54b
* Copy the appropriate files into the directories, e.g.:
cp /usr/local/games/rt2.old/rt2 bin-1.54a-x86/rt2
cp /usr/local/games/rt2.new/rt2 bin-1.54b-x86/rt2
cp /usr/local/games/rt2.old/default2.lng data-1.54a/
cp /usr/local/games/rt2.new/default2.lng data-1.54b/
* Copy the patch README into the new data directory, e.g:
cp /usr/local/games/rt2.new/README-1.54b data-1.54b/README-1.54b
* Copy the patch tools image directory to a new patch directory tree, e.g:
cp -av ~/loki_patch/image rt2-1.54b-x86
* Generate deltas of the binaries and data files.
make_patch rt2-1.54b-x86/patch.dat delta-install bin-1.54a-x86 bin-1.54b-x86
make_patch rt2-1.54b-x86/patch.dat delta-install data-1.54a-x86 data-1.54b-x86
The make_patch tool is very flexible, run it without any options to see a list of commands that it recognizes.
* Customize the patch description file, patch.dat, if necessary, e.g.
vi rt2-1.54b-x86/patch.dat
* Copy the README into the patch directory, e.g:
cp data-1.54b/README-1.54b rt2-1.54b-x86/README.txt
This file is shown to the user before they apply the patch.
* Pack the patch archive, e.g:
makeself.sh rt2-1.54b-x86 rt2-1.54b-x86.run "Railroad Tycoon II 1.54b update" ./apply-patch.sh
* Test the patch on a fresh install, e.g:
# remove old versions, install from CD, patch up to current level
sh rt2-1.54b-x86.run
* Generate the GPG signature, named patch.sig, e.g:
gpg --secret-keyring /mnt/cdrom/secring.gpg --detach-sign rt2-1.54b-x86.run
* Generate the MD5 checksum, named patch.md5, e.g:
md5sum rt2-1.54b-x86.run >rt2-1.54b-x86.run.md5
* Generate the README, named patch.txt, e.g:
cp rt2-1.54b-x86/README.txt rt2-1.54b-x86.run.txt
* Generate the Loki Update Tool entry for the patch, e.g:
loki_patch --info rt2-1.54b-x86/patch.dat >>updates.txt
* Copy the patch to your public relase directory and you're done!
