I can create a installer package for say the 1.0 version of my
product suite. Beyond a few applications, there's a large number of
supporting frameworks and files. Great. Now, I need to edit two of
the largish applications for a 1.0.1 release. In the old days, we
could use VISE and patch the two largish applications, probably
using whatever binary diffing format they have.
Is there any such process for the Apple Installer? Is there a way to
patch rather than overwrite? Is creating the upgrade installer just
a matter of having a sparse installation folder and archiving that,
or are there other instructions?
There isn't explicit support for this, but we're considering it for a
future release.
The workaround is pretty simple: just create a package that the
installer won't realize is an 'upgrade' of your old package, and only
put the modified files in the new package.
That gives you a 'sparse' package, and the installer won't delete any
of the missing files as long as it doesn't match your package to the
older version by CFBundleID or package name.
