I tried dodging that bullet for a long time, with less and less
success. Every successive project I'd end up with or new environment
I'd try would wind up with ad hoc bits of glue code to try to fool bits
of mit kerberos, or afs into doing the right thing, with successively
less useful results.
So, my current effort in this direction is here:
a compile_et (based on perl) that can produce 3 different
kinds of initialization, also handles
heimdal extensions, non-standard bases, etc.
mutex code to handle list locking
key alloc code which leaks keys (instead of hanging).
non-standard base handling (a la heimdal, to suit afs)
'afserror.et' - using non-standard bases.
negative error numbers
random variations on remove_error_table,
initialize_error_table_r, error_table_name, etc.
I don't have anything here that does the mit k5 ".init" hack yet.
I suppose it's easy enough to put in.
I had been thinking of this as more of a 'reference' implementation
than its own separate thing - so there's more work needed to make
this truely something other people would want to use.
At some point, I want to hack up some version of openafs to support
some equivalent to "with-system-et". The current libafsrpc.so
error_message annoys me. I also want to find all cases in openafs where
it assumes "all negative numbers are rpc errors" and constrain that to
be "-1000..-1". This might be a small project of mine at the next
AFS hackathon, if it doesn't happen sooner.
At one point, I told a number of the various com_err developers
about the compile_et I was working on - an earlier version of
what's included here.
I wish I had more time to proselytize people on the virtues of
"--with-system-et" non-standard base handling, and general
