New submission from Bill Janssen <bill.jans...@gmail.com>:
I'm trying to create a CAB file containing about 69MB of data, in 4555 files.
msilib fails in CAB.commit():
$ python build-msi-installer.py /c/UpLib/1.7.9 ~/uplib 1.7.9 ./uplib-1.7.9.msi

(I added a bit of code to print out the Media table record, and the size of the
file created with FCICreate.)
This works fine if I choose a slightly smaller subset, such as
/c/UpLib/1.7.9/lib, for instance. So I'm guessing this is a memory problem; at
some point there's just not enough memory to open the MSI file and load the
Media table.
I opened the MSI file with orca and sure enough, there is no Media table in it.
Not sure how to take that, though; perhaps the table only appears after a
record has been written to it.
Another reason to allow multiple CAB files in a single installer?
