--------------------+-------------------------------------------------------
With r36890 I've enabled UUID stamping of pbc's for the t/native_pbc/
tests. tools/dev/pbc_header.pl --up works now again.
In order to enable UUID's (uuid_type=1) for all PBC's I plan the
following:
- read the UUID, the md5 fingerprint of PBC_COMPAT with
Parrot::BuildUtils::generate_pbc_fingerprint() at Configure.pl
- uuid_size = 12, so that the new padding in the header will be 2
instead of 14 and the header size before the directory stay the same.
- store the pbc_fingerprint as PBC_UUID in config.h for packfile.c
- write every pbc with this UUID
- check the UUID when reading pbc's and warn
when reading incompatible PBC's, different UUID's.
- error on reading newer bytecode versions,
allow reading older versions. That was the original
intention at least.
