This script generates the patches required to support incremental
|
|
download of Panda3D packages. It can be run as a post-process on a
|
|
directory hierarchy created by ppackage; it will examine the directory
|
|
hierarchy, and create any patches that appear to be missing.
|
|
|
|
You may run ppackage on the same directory hierarchy as many times as
|
|
you like, without creating patches. You may then download and test
|
|
the resulting files--users connecting to the tree without fresh
|
|
patches will be forced to download the entire file, instead of making
|
|
an incremental download, but the entire process will work otherwise.
|
|
When you are satisfied that all of the files are ready to be released,
|
|
you may run ppackage on the directory hierarchy to generate the
|
|
required patches.
|
|
|
|
Generating the patches just before final release is a good idea to
|
|
limit the number of trivially small patches that are created. Each
|
|
time this script is run, a patch is created from the previous version,
|
|
and these patches daisy-chain together to define a complete update
|
|
sequence. If you run this script on internal releases, you will
|
|
generate a long chain of small patches that your users must download;
|
|
this is pointless if there is no possibility of anyone having
|
|
downloaded one of the intervening versions.
|
|
|
|
You can also generate patches with the -p option to ppackage, but that
|
|
only generates patches for the specific packages built by that
|
|
invocation of ppackage. If you use the ppatcher script instead, it
|
|
will generate patches for all packages (or the set of packages that
|
|
you name specifically).
|
|
|
|
This script is actually a wrapper around Panda's PatchMaker.py.
|
|
|
|
Usage:
|
|
|
|
%(prog)s [opts] [packageName1 .. packageNameN]
|
|
|
|
Parameters:
|
|
|
|
packageName1 .. packageNameN
|
|
Specify the names of the package(s) you wish to generate patches
|
|
for. This allows you to build patches for only a subset of the
|
|
packages found in the tree. If you omit these parameters, patches
|
|
are built for all packages that require them.
|
|
|
|
Options:
|
|
|
|
-i install_dir
|
|
The full path to the install directory. This should be the same
|
|
directory named by the -i parameter to ppackage.
|
|
|
|
-h
