* nx-shell.tcl, *sh.in: Rename nx::shell2 to nx::shell and remove old nx::shell implemenetation. * makefile.vc: Use new shell object in shell target.

  1. … 4 more files in changeset.
- fix testx (filterGuards); when compiled without assertions, a test case was skipped, that created an object "b"; the following test produced different results when b was created or recreated - avoid global

* Updated copyright dates and copyright notices

*xotcl2.tcl (Class->unknown): Use ::nsf::current explicitly to avoid nx/xotcl self hickups

xotcl2 unknown: fix regressions due to uplevel mambo-jumbo

xotcl2.tcl: Make sure that Class->unknown bypasses filter and mixin frames

nx::shell2: Rewrote in-shell exit support to avoid Tcl's native exit and to unwind gracefully to avoid NSF refcount leaks on exit; bumped package number

  1. … 4 more files in changeset.
Some cleanup and adding basic test cases

  1. … 4 more files in changeset.
nx::shell reform: Provide an alternative nx::shell impl (nx::shell2), used by all four shell scripts. nx::shell2 builds on Tcl's event loop, rather than while + update. This avoids blocking the Tk main window (update). In addition, nx::shell2 is closer to Tcl's native shells (e.g., no extra lines on enter, catches EOF).

  1. … 3 more files in changeset.
xotcl2: - added "-returns" flag to XOTcl's instprocs/procs and methods, very similar to "-returns" in nx - extended serializer to handle "-returns" flag - extended regression test

  1. … 2 more files in changeset.
- bump version number of XOTcl to 2.1

  1. … 1 more file in changeset.
- turned all for-loops controlled over a nonnull value into while loops - updated TODO, copyright notices, version number

  1. … 10 more files in changeset.
Slot trace reform: - redesign of slot interface of traces from * variables contains cmds and variable references to * slot specific methods with the same interface as slot-setters - new: * specify flag "-trace" with a list of values "get", "set", "default" * when flag is set, a trace will be registered calling methods value=get obj variable value=set obj variable value value=default obj variable on the slot (actually the first two are identical with the methods used for slot-defined accessors) - updated regression test * new flag "-notrace" for "nsf::var::set" and "nsf::var::get"

xotclsh, xowish: Make sure minor versions >2.1 are accepted

nx::shell: Have xotclsh and xowish use nx::shell

- added flags "-debug" and "-deprecated" to XOTcl 2 "instproc", "proc", "instforward" and "forward" methods

  1. … 2 more files in changeset.
serializer: - added handling of "-debug" and "-deprecated" in serializer - allow export of nsfprocs via "exportMethods declaration" in order to keep otherwise excluded cmds in the result. this allows us to keep nsf::debug::* or nsf::deprecated definitions in the blueprint in OpenACS. - hardened serializer (use e.g. "::namespace" instead of "namespace" when there is a potential conflict with a method named "namespace", prefer nsf::directdispatch, etc.) - extended regression test

- Fixed a bug that disallowed the combination of valuecmd and valuechangedcmd for a single property (many thanks to Zoran for pointing this out)

Removed implicit substdefault for configure parameters in nx:

- The syntax of substdefault for method parameters and configure

parameters was different. For method parameters, it was necessary to

specify :substdefault per parameter to activate it, for configure

parameter is was based in the XOTcl tradition on the content of the

default (whether it contains [...]) One problem is, that there was

no easy way to turn this feature off. If one wants to provide a

script block as a default, it was necessary to escape all square

brackets.

- Now, in nx, one has to specify :substdefault for configure

parameter explicitly as well, syntax for configure and method

parameters is the same.

- XOTcl 2.0 keeps implicit substdefaults (backward compatible)

- fix bug: never try to substdefault, when there is no default given.

- new command nsf::method::forward::property in analogy to nsf::method::property for reading+writing introspection of forwarders (important for serializer, when different target objects are specified, to map the per-object forwarder) - extended regression test - bumped version number of serializer to 2.1

nsf.c: - dropped unused object::info::is - renamed ::nsf::methods::class::info::filtermethods -> ::nsf::methods::class::info::filters ::nsf::methods::object::info::filtermethods -> ::nsf::methods::object::info::filters ::nsf::methods::class::info::mixinclasses -> ::nsf::methods::class::info::mixins ::nsf::methods::object::info::mixinclasses -> ::nsf::methods::object::info::mixins

- improve spelling

nsf.c, gentclAPI.tcl: - new argument types "virtualobjectargs" and "virtualclassargs" for context-specific argument resolutions: when a context object is provided, arguments of type "virtualobjectargs" are determined based on the slots applicable for the object (like "... lookup ..."), arguments of type "virtualclassargs" are resolved against a class. These types are used as follows: /obj/ configure /virtualobjectargs/ /cls/ create /name/ /virtualclassargs/ /cls/ recreate /name/ /virtualclassargs/ /cls/ new ?-childof /obj/? /virtualclassargs/ This new feature allows us to provide better error messages and to make much of the "... info ... configure parameter ..." infrastructure much less important. - For "virtualclassargs" we need the functionality to obtain from the C-Code based on a class the configure parameters applicable to objects of this class. - add argument "-context ..." to "cmd::info" to pass the context object (so far the only place where the context-object is used) - object system configuration parameters changes: new: -class.configureparameter new: -object.configureparameter removed: -class.objectparameter

- minor cleanup

nsf.c - force again literal "-guard" in a "mixinreg" type to avoid potential confusions - Base nsfRelationSet for mixins on cmds rather than TclObjs to avoid confusions and duplication of guard detection logic - Add interp to NsfMixinregGet() and NsfFilterregGet() to be able to return error messages - return more error message from mixinreg converter - provide at least minimal support for "funny class names" (i.e. containing spaces) - FinalObjectDeletion: don't enforce namespace = 1 for cases with wierd namespace deletion order - extended regression test
