[a18894] by Christophe Rhodes Christophe Rhodes compress most unibyte-external-format definitions

All the unibyte-mapper-based external-formats had huge amounts of
cut-and-pasted code, differing only in names of functions. This is,
oddly enough, a clear case for abstracting away the repeated code into a

In the process, convert them to the multibyte apparatus, which has support
for the nice restarts, and remove the too-simple unibyte

Include a far-from-comprehensive set of tests, which are mostly for
iso-8859-x formats

[314ebe] by Christophe Rhodes Christophe Rhodes bug fixes in unibyte external formats

* handling undefined codepoints:

There's a difference between "unassigned codepoint", represented as
(<code> nil), and "codepoint mapping to character with that codepoint",
represented by the absence of an entry in the exceptions list. Simply
testing for trueness of (cadr (assoc <code> exceptions)) isn't good
enough; test for trueness of (cdr (assoc ...)) and use the car if so.

* undefined codepoints as the first exception:

If the first exception to code<->byte is an undefined character, as for
example in iso-8859-8, the lowest-code exception was computed wrongly,
leading to incorrect encoding.

[ed53de] by Christophe Rhodes Christophe Rhodes Support for :REPLACEMENT external-format / encoding modifier

For a given keyword :foo naming an encoding, allow an external-format
(:foo :replacement <character>) such that any stream or octet coding
errors are automatically treated by using the <character> as replacement

To do this, wrap each of the functions in the external-format object
named by the keyword with a function establishing handlers for the
exceptional conditions. At the moment, the output restarts for c-string
external format conversion are not implemented (so handle specific condition

[8a9352] by Nikodemus Siivola Nikodemus Siivola additional allocation information

* SB-INTROSPECT:ALLOCATION-INFORMATION also reports on boxedness of
the page the object resides on.

* When heap statistics are printed, always print the details of the
pseudo-static generation. Make print_generation_stats extern so it
can be called from lisp.

[7cf582] by Christophe Rhodes Christophe Rhodes make the utf-8 external format more robust

Detect all malformed sequences, including attempts to decode or encode
Unicode surrogate codepoints (disallowed by the Unicode definition of
UTF-8). Some error tests change behaviour, and some (unexported)
condition classes are not triggered under the same circumstances any

Also, handle null-termination on a successful conversion of an empty range of
a nil array.

[75476d] by Christophe Rhodes Christophe Rhodes external-format restart enhancements

* OUTPUT-REPLACEMENT restart for fd-stream external-formats, taking a
string designator argument and attempting to encode that instead of the
erroneous output;

* fixes for the FORCE-END-OF-FILE fd-stream external-format restart, using
a somewhat involved call / return protocol for communicating out-of-band
information between output routines and drivers;

* INPUT-REPLACEMENT restart for fd-stream external-formats, again with
complicated out-of-band information communication. This also interacts

* fix the ATTEMPT-RESYNC restart (and similar) at or near the end of file,
ensuring that there is always a valid CATCH tag to be THROWN to;

* fix a double-error case in the USE-VALUE restart for unibyte octet

* bandage fix for mb-util decoding-error USE-VALUE restart -- there's more
factoring to be done, but this fixes lp #314939

type declaration in the whole system that clisp doesn't understand, we might
as well fix it. Report and patch by Josh Elasser, lp #396597.

[95591e] by Christophe Rhodes Christophe Rhodes Fix slot-value on specialized parameters in SVUC methods

The slot accessors' functions were being computed too early, requiring a
wrapper (for the PV optimization) when none was available. The fix
delays the computation by the usual trick of installing a closure that
will perform the slot accessor computation on demand.

Include a correct MOP test for this (slightly hard because of
constraints about order of instantiation: see lp #473699, reported by
Lars Rune Nodstal).

* Add two new Xref functions to SB-INTROSPECT:

WHO-SPECIALIZES-DIRECTLY returns method definitions which
specialize one the designated class itself.

WHO-SPECIALIZES-GENERALLY returns methods definitions which
specialize on the designated class, or subclasses of it.

Both take CLASS-EQ, and EQL specializers into account.

* Refactor xref tests, and add tests for the two new functions.

* Fix sb-introspect.asd to perform the test-op with a *D-P-D* bound
to contrib/sb-introspect/.

[4363cb] by Christophe Rhodes Christophe Rhodes defend against full MAKE-ARRAY before the type system is ready

This is basically defence against bugs of the form lp #316323, where the
wrong answer comes out of a make-array before SUBTYPEP is working
properly. We should be able to arrange the build so that we never have
to do a full MAKE-ARRAY before we're ready for it.

Slight modifications of a couple of macros: VOP-related and multibyte
encoding-related. There should be no user-visible change.

[b76a2a] by Christophe Rhodes Christophe Rhodes minor portability fix

Clozure CL issues full warnings at compile time if individual clauses in
typecases are shadowed by others; this makes writing portable
warning-free typecases for character types a little bit tricky. In the
case of the FORMAT directive finders, though, the workaround is
straightforward because the whole of the CHARACTER branch in the
typecases can be removed.

While we're at it, fix the theoretical portability bug that we were
calling the host's CHAR-CODE on BASE-CHARs to fill data structures later
to be accessed using the target's CHAR-CODE. (Theoretical because all
implementations at present agree on CHAR-CODE for BASE-CHARs).

(This commit does not suffice to allow Clozure CL to build SBCL)
