cleanup after TIP 660

Fixed warnings detected with branch "disabletcl8api"

The Tcl9 native interface is based on "Tcl_Size" instead of "int", but

the default mode hides these differences via some macro-magic. Typical

such cases are API calls like:

Tcl_ListObjLength(interp, methodObj, &length);

Tcl_ListObjGetElements(interp, methodObj, &oc, &ov)

The macro-magic queries the size of the provided parameters and uses

the old or new interface depending on it (while hiding some more

potential problems, a compiler can detect). The branch

"disabletcl8api" removes the macro-magic and reveals the potential

problem areas, where the code is still depending on the old 32bit


This commit fixes such cases and the collateral damage.

Provide support for TIP 627 (Tcl 8.7a6+ and Tcl 9)

TIP 627 introduces support for > 2^31 elements in object vectors

(e.g., number of words in a single Tcl command). For details, see


To provide also backwards compatibility, this change uses the macros

New feature: added support for return value checker for nsf::proc

One can now specify "-returns ...." in nsf::proc commands the same way

as in nx/XOTcl2 methods.

nsf::proc ... /procName/ /arguments/ ?-returns /valueconstraint/? /body/

When return value checkers are defined, these are returned by the

usual introspection interface.

% nsf::proc ::foo {-a:integer} -returns integer {return 1}

% nsf::cmd::info definition ::foo

::nsf::proc ::foo -a:integer -returns integer {return 1}

% nsf::cmd::info returns ::foo


The regression test was extended to cover these cases.

Fix bug, where Tcl's "string is" checker modified result, when used as a return value checker

The new code saves and restores the original result value.

The regression test was extended.

Many thanks to Antonio Pisano for pointing out this issue.

generalize handling of isTYPE calls by defining CHARTTYPE

The macro was developed earlier on NaviServer, and is used

in nsf for "upper", "space" and "alpha" character checkers

reduce warnings for other compilers

reduce warnings for clang

clang has no "-Wmaybe-uninitialized" flag

address the maybe-uninitialized warnings

I do not really like the approach based on pragmas, but i do even

less like the warnings, when compiled with -pedantic

reduced compiler warnings when compiling against Tcl 8.6* with TIDY settings

Leave the code for potential future debugging purposes

Added support for compiling with Tcl 9.0 (Many Thanks to Jan Nijtmans for first steps)

This version compiles cleanly at least with Tcl 8.6.* and Tcl 9.0 (fossil trunk),

having -pedantic and -Wextra defined.

cleanup: avoid memory leak in cases the Tcl_DictObjPut fails

added option "-asdict" to nsf::parseargs

The new option makes it easier to process the parsed argument in different

Bug fix: include alias to object in "info methods -path"

Previously, it was not possible to define an alias to an object for

NaviServer, since it was not returned by "info methods -path" and

was therefore not included in the blueprint.

Extended regression test.

* nsf.c (ObjectDispatch): Fix another invalid read of a cached cmd structure (NsfColonCommandContext)

* nsf.c (NsfUnsetTrace, VolatileMethod): Plug a post-mortem memleak related to volatile objects (The Tcl_Obj carrying an auto-qualified object name was not cleaned up properly during interp shutdown because the matching decrement operations used to be disabled during shutdown.)

* nsf.c (ObjectDispatch): Fix invalid read as indicated by valgrind by guarding access to intrep.

fixed false positive from facebook infer 1.1.0

reduced warnings from clang12 static checker (null value passed to non-null arguments, dead assignment, ...)

Merge branch 'master' of ssh://alice.wu-wien.ac.at/usr/local/src/git-repo/nsf

First attempt to fight valgrind warning on cond/unintialized jump

* nsf.c (Nsf_Init): Plumb a small memory leak due to not clearing mp_int data. Make sure _not_ to use mp_clear (TIP 538).
