Re: [Gnu-arch-users] in-tree pristines fatally wounded (merge-fest etc)

[Robert Collins]

To use the new features, one might do this:

in ~/arch-params/hook  (*)
===
#!/bin/sh
case "$1" in
  find-pristine|make-pristine|make-tmp-pristine)
        tla library-add --sparse ${ARCH_ARCHIVE}/${ARCH_REVISION}
    ;;
esac
===

mkdir ~/arch/revisionlibrary
tla my-revision-library ~/arch/revisionlibrary

tla get --hard-links --sparse address@hidden/tla--devo--1.1 tla
cd tla
tla changes

the get command will seed the library, and not create a pristine.
the changes command will use the hook, find it in the ilbrary (or add it
if needed - say you already have a working dir), and then use the
instance  in the library.

(*) ~/.arch-params/hook is a essential bit of component for any tla
user. It's not part of the distribution, as it's locally customised.

So, here is a request for 'someone' to do a little bit of hacking.

1) Create a new command 'hook-default-contents' 
  This command will dump out a sample hook file that lists all the
possible hooks, and does harmless defaults. I.e. uses a revision library
IFF one exists. The initial contents could be all no-ops.
2) Alter libarch/hooks.c:arch_run_hook() so that,
  If the hook file doesn't exist, one is created with the output from
'hook-default-contents', and is made user executable. This file is then
used.

Anyone that doesn't want any hooks can just zap the contents to be a
null script.

This would IMO be of great assistance in making tla setup easier for
users.
