1 # This file shows the history of incompatible changes to
2 # Parrot that invalidated existing PBC (Parrot Byte Code) files.
4 # The text in this file is also the base of the
5 # fingerprint inside PBCs and Parrot which is used
8 # Its probably not complete or out of date - but a start
9 # to get less restrictive fingerprint tests.
11 # Currently known actions that should be entered here
12 # (and invalidate PBC are):
14 # - bumping Parrot version
15 # - deleting/changing/inserting existing ops in ops.num
16 # - changing operands of existing ops
17 # - adding/deleting/renaming a PMC to classes
18 # - changes in the packfile format itself
19 # - changes to any PMCs that are frozen into the .pbc like
20 # ParrotInterpreter (HLL_info), Subs and more
21 # - other core changes that invalidate byte code :)
23 # After changing PBC_COMPAT either disable t/native_pbc tests or
24 # better, if you have an i386 box at hand, regenerate the PBCs
25 # with tools/dev/mk_native_pbc and commit the changes
27 # or TODO much better: all .pbc files should make-depend on PBC_COMPAT
29 # please insert tab separated entries at the top of the list
