GENERATE SELF-EXTRACTING EXECUTABLE
|
|
-----------------------------------
|
|
|
|
This directory contains the files necessary for performing the generation
|
|
of the self-extracting-executable. The main entry-point is GenerateCAB(),
|
|
which in turn manipulates INF and CDF objects,
|
|
|
|
gencab - CAB control module.
|
|
geninf - INF object methods.
|
|
gencdf - CDF object methods.
|
|
|
|
This design has seperated responsibilities of the various components into
|
|
object-type modules. For example, anything which has to do with an INF-file
|
|
is handled in the (geninf.c/geninf.h) modules. Likewise, the CDF routines
|
|
use an INF interface to obtain information concerning the INF. Previous
|
|
implementations of which this code was derived, utilized a monolithic approach
|
|
where the CDF, INF and CAB routines had integral knowledge of each others
|
|
functionality.
|
|
|
|
We diverged from this approach to a more object-oriented design which we
|
|
believe is more maintainable and somewhat self-documenting.
|
|
|
|
|
|
Structure/Flow:
|
|
|
|
cab:
|
|
|
|
if (Create INF Object) {
|
|
|
|
if (Create CDF Object) {
|
|
|
|
query CDF, INF objects for pertinent information.
|
|
|
|
if (CDF newer than CAB) {
|
|
|
|
Execute IExpress to generate new cab.
|
|
|
|
} else {
|
|
|
|
utilize cached cabname.
|
|
}
|
|
|
|
Free CDF Object.
|
|
}
|
|
|
|
Free INF Object.
|
|
}
|
|
|
|
return cabname.

Issues:
|
|
-------
|
|
|
|
1) How do we determine op-sys versioning and archetecture? We need this
|
|
to determine where to pull our INF driver-files. This should be passed
|
|
in at GenerateCAB() time.
|
|
|
|
2) Generating an INF (to be or not to be)...although not huge, this could
|
|
change our implementating of caching of the CDF/CAB files. Currently,
|
|
we will generate a layout-file (sort of).
