I looked at this a couple of weeks ago - my big problem was being
entirely unable to read binary files in JScript. (Any hints welcome!)
I've used AODB.Stream for this... but its really damn slow and you need
a lot of copying to get the data into a string object or something else
that has an .length property (which is intensively used in most MD5
implementations :).
My opinion is that in this sort of project, speed isn't really an issue.
I install packages and maintain packages on lots of machines and really
don't care if it takes a while: I can get a coffee or do something else
while it finishes. If we can do the job natively in JScript, I think
that would be easier from the point of view of distribution.
I also want to have it native, but I think WPKG needs to run as fast as
possible, as our setup pauses the user until WPKG is done. You shouldn't
install software while the user is logged in, this will just make things
more complicated. So I don't want to bother the users with damn long
install sessions, because they are already waiting long time until the
software gets downloaded. Someone needs to speed up the MD5 JScript
code, but this is not me. :)
Perhaps we could provide a wpkg-config.xml file in the same directory
which would contain preferences:
<wpkg-conf>
<option "md5">
<option-type name="external" value="true" />
<option-type name="command" value="\\server\share\utils\md5sum.exe
/makesum %s" />
</option>
</wpkg-conf>
If this file exists, we read it and parse it. The options above, for
example, might direct wpkg to over-ride a built in MD5 function with the
executable on the share called with some appropriate arguments. This
might be useful for other things - the default mode for wpkg to run
without command line arguments, perhaps.
Having a configfile for the WPKG system or lets say that we can bump
the profile.xml to have profile based WPKG configurations would be
really useful. A lot of features need to be adjusted in the source
already which is not really the way to go.
