Object-method Reform: - changed interface to object specific commands by requiring an ensemble named "object". The rational behind is essentially to use always the same info command to retrieve object specific methods, no matter whether these are defined on a plain object or an a class object (does not break the "contract" what e.g. "info method" returns).

Now we define methods via:

/cls/ method foo {args} {...body...}

/cls/ object method foo {args} {...body...}

/obj/ object method foo {args} {...body...}

Similarly, aliases, forwards and mixins are defined, e.g.

/cls/ mixin add ...

/cls/ object mixin add ...

/obj/ object mixin add ...

/obj/ require object method ...

The same change propagated as well to the "info" method.

Now we have:

/cls/ info methods ...

/cls/ info object methods ...

/obj/ info object methods ...

Similar, the object parametererization uses

/cls/ create obj -object-mixin M

/cls/ create obj -object-filter f

/metacls/ create cls -mixin M1 -object-mixin M2

/metacls/ create cls -filter f1 -object-filter f2

- as a consequence,

a) "/cls/ class method ...",

"/cls/ class alias ...",

"/cls/ class forward ...",

"/cls/ class filter ...",

"/cls/ class mixin ...",

"/cls/ class info ..."

"/obj/ class method require method ..."

"/obj/ class method require public method ..."

"/obj/ class method require protected method ..."

"/obj/ class method require private method ..."

were dropped

b) "/obj/ method ....",

"/obj/ alias ....",

"/obj/ forward ...."

"/obj/ filter ...."

"/obj/ mixin ...."

"/obj/ info method*"

"/cls/ create obj -mixin M"

"/cls/ create obj -filter f"

"/obj/ method require method ..."

"/obj/ method require public method ..."

"/obj/ method require protected method ..."

"/obj/ method require private method ..."

were dropped

- added package nx::class to allow optionally the "class" notation

"/cls/ class method ..." (and friends, see (a)), and

"/cls/ class info ...

- added package nx::plain-object-method to allow optionally plain method

b) "/obj/ method ...." (and friends, see (b))

- add support to slots to use ensemble methods as setters

nsf.c: - don't convert obj types tclCmdName and parsedVarNameType to instanceMethodObjType

- cleanup on nsfObj.c

  1. … 2 more files in changeset.
- minor cleanup

- added MixinregDupInternalRep() and FilterregDupInternalRep

nsf.c: - new cmd for debugging: nsf::__db_show_obj - added MethodDupInternalRep() and FlagDupInternalRep() since they appear to be required in Tcl 8.6b2.

  1. … 6 more files in changeset.
nsf.c: - reform of method lookup. new code uses NsfInstanceMethodObjType and NsfObjectMethodObjType to reuse earlier lookup results. Improved speed for for methods with primitive bodies (over version before argument parse reform: 10%-43%. - additional compile-time option: METHOD_OBJECT_TRACE

  1. … 4 more files in changeset.
- provide more hints for gcc

- reform of argument parse. new parser uses NsfFlagObjType to reuse earlier parse resuslts. Improved speed for for methods with primitive bodies: 5%-25%.

* per-thread MEM_COUNT tested with aolserver/naviserver * removed INTERP macros for MEM_COUNT (since we use now per-thread tables instead of per-interp tables as in the first implementation)

  1. … 5 more files in changeset.
- nsf.c: * enabled MEM_COUNT debugging for multi-threaded apps. We collect the MEM_COUNT statistics now per interp. Therefore, we have to pass around "interp" in case where alloc() and free() or refCount functions are used (textually, a big change) * verified, that nsf runs clean in aolserver/naviserver (all INCR_REF_COUNTS all balanced)

  1. … 8 more files in changeset.
- nsf.c: * refined refcounting debugging * fixed various refcounting bugs, especially in error cases. * added explicit INCR_REF_COUNTs on Tcl_Objs with 0-refCount to ease debugging

  1. … 9 more files in changeset.
- removed warning about strict-aliasing rules

  1. … 3 more files in changeset.
- moved mixin reg type converter to a new file (nsfObj.c) - added NsfFilterregObjType, to provide a converter for filter registration similar to mixin registrations - replaced dummy dupIntRepProc and updateStringProc in nsfObj.c by NULL
