- Fixed an issue when accessing partly initialised NsfParamDefs (created e.g. by [::nsf::methodproperty ... returns]) from [info method] subcommands, previously leading to invalid memory accesses. Added a test to tests/returns.test. - Minor correction: xotcl2's method_handle_to_xotcl was not aware of the change to "class-object" as scope modifier.

Accomplishments: - Completed a first version of the sandboxed (partial) evaluation of Tcl source artifacts (packages, script files, C extensions) based on a dedicated child/slave interp environment: see ::nx::doc::Sandbox; the test suite and the test documentation builts run on it. - Based on this infrastructure, we can now generate a snapshot of a program's structure to be documented (and contrast it to the explicitly documented structure). - Added simplistic css sprites for visualising the doc entity status (extra, missing, mismatch, complete); see also library/lib/doc-assets/status.svg and library/lib/doc-assets/status.png - The entity status is printed optionally along with the print name of an entity - Added switch-like parts to represent properties of doc entities: @deprecated, @stashed, @c-implemented, @syshook. The implementation and use of ::nx::doc::SwitchAttribute should be reviewed after having figured out how to proceed using "switching" objparams. - I provide a multi-property dispatcher as doc-syntactic sugar and for mere convenience: @property

Various:

- Corrected some div-boxing mess in the templates

- Added a filtered helper to process entity collections

- Made the mixin layer infrastructure more symmetric (a revoke operation).

- Added tracers for ::nsf::method and ::nsf::alias (remains to be completed)

- Renamed ::nx::doc to ::nx::processor and turned it into another

mixin layer to trace the doc entity creation in e.g. readin()

- Companion (*.nxd) files: Revised the handling of companion

files. Temporarily moved generic/nsf.nxd in the top-level

directory. We need to find a permanent place as its location is

currently derived from the location of the shared extension. A

candidate is doc/ but this is not linked to the shared extension

location at all.

- processor.readin() now returns a collection of entities created

during its execution.

- Improved robustedness and orthogonality: destroy hooks; the

tag-dispatcher can now handle empty comment lines; when placing NSF

object tracer, we now use the freshly added introspection of an

object system's method aliases.

- Conditionally disabling redefine protection (based on the presence of a global var ::nsf::bootstrap) failed due to the result flag not being set to TCL_OK in this case. - Adding a (redundant) [package provide nsf /version/] to the ifneeded script in nsf's pkgIndex.tcl. Background: [load] is only executed once (leaving aside [unload]) for a given interp. Hence, the initialization function and its Tcl_PkgProvide() call are only performed once. A subsequent [package forget] and [package req] barfs because the package version information is removed internally upon [package forget]:

"attempt to provide package nsf 2.0.0 failed: no version of package

nsf provided"

The Tcl docu provides hints on this requirement (for C

extensions); see man for [package provide]:

"[package provide] is typically invoked once as part of an ifneeded

script, and again by the package itself when it is finally loaded."

Note that most C-extension packages (sqlite, tdom) do not meet this

requirement.

- changed relation handling by evaluating the relationcmd in the parent context to keep evaluation order. - extend introspection "nsf::configure objectsystem": the command returns now all system methods in the syntax of nsf::createobjectsystem - "nsf::createobjectsystem" creates now a warning when an existing objectsystem is redefined and ignores the new definition attempt. This was done with the purpose to allow "package forget nx; package require nx" - Allow overwriting of redefine protected method during bootstrap to ease "package forget nx; package require nx" - forward had just "-objscope", no general "-frame method|object". Since forwarder have client data, they always push a method frame. So, the situation is different to nsd::alias and ::nsf::dispatch. Therefore, the flag "-objscope" was renamed to "-objectframe" to provide better consistency with "-frame object" - fixed bug, where error handling of invalid options in ForwardProcessOptions() could lead to a crash - return forwardoption "-earlybinding" via instrospection - extended regression test

- disallow object parameter of type "switch" to avoid possible confusion between (a) providing a value for the o.p., (b) calling it as a setter, and (c) calling it as a getter. For providing a value, no arg is used for switch. For calling a setter, it is necessary to provide a value even for a switch. - disallow type "switch" in setter definiton (use boolean instead) - disallow type "switch" for positional arguments (use boolean instead) - extended regression test

Squashed commit of the following:

commit 370f47d26099dd8cda4125de67048461edb797a9

Author: ssoberni <stefan.sobernig@wu-wien.ac.at>

Date: Thu Nov 4 10:56:11 2010 +0100

Due to recent changes in InterpColonVarResolver() to handle the

slow-path execution the byte-compiled [variable], an unwanted

interaction between ::nsf::setter, *certain* per-object namespaces,

and the ColonCmd()-based invocation of setter methods became

visible. In short: Given a pre-existing Tcl namespace and the

colon-prefixed call specification to a setter method,

InterpColonVarResolver() handles the var resolution request issued by

the setter method (or SetInstVar(), more precisely). In a

colon-prefixed call, the Tcl_Obj carrying the setter method name and

used to lookup the object variable contains the ":". At the same time,

the per-object namespace causes the TCL_NAMESPACE_ONLY flag to be set

which causes InterpColonVarResolver() to pass on the request. In this

setting, we end up with colon-prefixed object variables! See

tests/parameter.test for an explanatory test case. For the time being,

I fixed this by preserving and using the original, colon-free Tcl_Obj

indicating the variable name in the client data structure of the

settercmd.
