- reduce verbosity

- make XOTcl_FrameDecls transparent (use variable declarations in place instead of the macro) - fix variable shadowing bug in error handling (could cause crashes when initcmd lead to errors)

  1. … 1 more file in changeset.
- define RecreateObject() for internal call via diect invocation - doCleanup is just called by recreate; merge it into XOTclCRecreateMethod. Is method cleanup necessary? is recreate not sufficient?

- call c-implemented methods directly for XOTE_RECREATE as well (otherwise, create is faster than recreate)

- call c-implemented methods directly, when this is safe (implemented for XOTE_ALLOC, XOTE_CLEANUP, XOTE_CONFIGURE, XOTE_CREATE, XOTE_DEALLOC); this improves create/destroy speed by up to 15% - allocate namespaces for objects less eager - make nameing more consistent (change newObj into newObject when variable is an xotcl object)

  1. … 1 more file in changeset.
- fixing "-parameter" with empty content - more variable naming cleanup - fix line breaking in serializer for "exportedObjects"

  1. … 4 more files in changeset.
- fixed wrong name for per-object filter in RelationSlot - fixed condition in filter-incovation to top-level frames - added frametype to information returned by "info frame"

  1. … 4 more files in changeset.
- remove dependency from xotcl1 in handling of forwarders in method "copy" - further cleanup using "CONST char *", improving on naming conventions

  1. … 5 more files in changeset.
- further cleanup using "CONST char *"

  1. … 3 more files in changeset.
- use "CONST char *" in generated interface and below

  1. … 5 more files in changeset.
- defined "xotcl::current" as synonym for "::xotcl::self" - new options for ::xotcl::current current object == current current method == current proc current callingmethod == current callingproc - "self proc" and friends are for backward compatibility for xotcl1, "current method" and friends are for xotcl2 - namespace exported "::xotcl::current"

  1. … 4 more files in changeset.
- minor cleanup (varresolution test and comment)

  1. … 1 more file in changeset.
- enable compilation with assertion turned on (via NDEBUG) - fix potentially uninitialized flags for ArgumentCheck() - some further cleanup, tested with 32 bit under Mac OS X 10.6

  1. … 4 more files in changeset.
- keep variables defined from an CMETHOD frame local to this frame (e.g. initcmd, -nonleaf option, ...); previously variables without xotcl resolver prefix were defined globally - fix regression test according to previous item - generalize nonXotclObjectProcFrame() and rename it to activeProcFrame()^

  1. … 5 more files in changeset.
- working towards KEEP_VARS_IN_CMETHOD_FRAME

  1. … 3 more files in changeset.
- requireNameSpace: * fix potental crash in requireNameSpace in objscoped methods by swapping all vartable references in objscopes on stack to the vartable in the namespace, when it is created - extending regression test

  1. … 3 more files in changeset.
- renaming of instance variable specific primitiva for more constistency with ::xotcl::importvar:

::xotcl::exists -> ::xotcl::existsvar

::xotcl::setinstvar -> ::xotcl::setvar

  1. … 10 more files in changeset.
- removed XOTclCreateClass() and XOTclDeleteClass(); both are identical with XOTclCreateObject() and XOTclDeleteObject()

  1. … 3 more files in changeset.
- removed obsolete ::xotcl::configure option "cacheinterface"

  1. … 3 more files in changeset.
- added option "-nonleaf" for method alias - added introspection (for "info method definition") for "alias ... -nonleaf ..."

  1. … 3 more files in changeset.
- further naming cleanup

  1. … 1 more file in changeset.
- cleanup in stack handlers (naming, arguments)

  1. … 1 more file in changeset.
- initcmd: use for initcmds CMETHOD frames instead of OBJECT stack frames - initcmd: skip parent-stack frame's objscope for initcmd - changed hash-based lookup of children into a cmd-based lookup - extended regression test

  1. … 5 more files in changeset.
- fixed namespace handling on stack for objects with namespaces (before, it was possible that a variable was created in an object's namespace without -objscope) - as a consequence, ListChildren() had to be adjused, since it depended on the previous namespace handling on the stack - fixed object sesolving in NsDotVarResolver() (before, it was possible that NsDotVarResolver could create variables in the wrong namespace) - simplified NsDotVarResolver() - more cleanup in name resolver * USE_DOT is gone * XOTclDotDotCmd() removed * improved performance of InterpCompiledDotVarResolver() * made LookupVarFromTable() obsolete and removed it * renamed DotVarResolver() and friends to ColonVarResolver() etc. - extended regression test

  1. … 10 more files in changeset.
- renamed ::xotcl::valuecheck -> ::xotcl::parametercheck

  1. … 3 more files in changeset.
- renamed old "xotcl::is" -> "xotcl::objectproperty" - renamed old "xotcl::is2" -> "xotcl::is" - we have now is tests for objects in ::xotcl::objectproperty ::xotcl::objectproperty $obj object ::xotcl::objectproperty $obj class ::xotcl::objectproperty $obj baseclass ::xotcl::objectproperty $obj metaclass ::xotcl::objectproperty $obj type XXXX ::xotcl::objectproperty $obj hasmixin XXXX

- "::xotcl::is" is the higher level command,

supporting string contstraints "e.g. upper", user defined type checkers

and as well object properties (every parameter type supported for object

and method paameter). Examples:

::xotcl::is $obj object ?-type $type? ?-hasmixin $mixin?

::xotcl::is $cl class ?-type $type? ?-hasmixin $mixin?

::xotcl::is obj metaclass

::xotcl::is $num integer

::xotcl::is $string upper

- implemented 2nd level reference counting for paramObjType

- Unified on c-level "info class-mixin-of" and "info object-mixin-of" to "info mixinof ?-scope all|object|class? ?-closure? ?pattern? The former "info class-mixin-of" is now "info mixinof -scope class" - adapted xotcl1 layer for this change - extended experimental ::xotcl::is2 to handle flags -type and -hasmixin ::xotcl::is2 <obj> object ?-type <type>? ?-hasmixin <class>?

  1. … 8 more files in changeset.
- experimental checking function ::xotcl::is2 implemented, which generalizes between ::xotcl::is and ::xotcl::valuecheck (it is a valuecheck -nocomplain with an ::xotcl::is syntax and switched arguments)

  1. … 5 more files in changeset.
- centralize fetching of tcl-obj-types in xotcl_init

- experimental: allow to show built-in types provided that a) slot= is specified explicitely, and b) the specified slot is not the default slot. This should guarantee that we do not interfere with the predefined converters for the c-level interface. - incremented ref count on results of all-level converter - extended regression test
