cleanup after TIP 660

  1. … 2 more files in changeset.
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

https://core.tcl-lang.org/tips/doc/trunk/tip/627.md

To provide also backwards compatibility, this change uses the macros

TCL_COMMAND_OBJPROC, TCL_CREATEOBJCOMMAND, TCL_NRCALLOBJPROC,

TCL_NRCREATECOMMAND, TCL_OBJCMDPROC_T, and TCL_OBJC_T.

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

  1. … 1 more file in changeset.
reduce warnings from redefined constants

  1. … 1 more file in changeset.
Improve cleanness of compilation under gcc-11+ and "-pedantic" + -Wextra"

  1. … 1 more file in changeset.
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.

  1. … 20 more files in changeset.
added enumeration values

  1. … 5 more files in changeset.
Reduced usage of reserved identifiers [cert-dcl37-c,cert-dcl51-cpp]

  1. … 7 more files in changeset.
make clean compile, when TRACE flags are defined

  1. … 4 more files in changeset.
improve spelling: move closer to the linux documentation recommendations

  1. … 19 more files in changeset.
add missing EXTERN declarations

  1. … 4 more files in changeset.
avoid dangerous and potentially recursive macro definition "pure"

  1. … 3 more files in changeset.
improve spelling

  1. … 19 more files in changeset.
silence gcc7+: use attribute based approach for denoting fall through in case statements

  1. … 4 more files in changeset.
Improve consistency of naming nsf objects

Change http:// occurrences to https://, if applicable (URLs tested)

* nsf.c (NsfOUplevelMethod, NsfOUpvarMethod, NsfCallstackFindCallingContext): Reform of uplevel and upvar methods, based on the recent feedback by Zoran. First, uplevel and upvar methods, as well as [current callinglevel] now behave consistently (re frame skipping for mixin and filter transparency). If there is no innermost enclosing proc frame, the innermost non-proc (e.g., namespace) frame is selected (rather than a "#0" as default). Second, argument handling for both uplevel (i.e., level sniffing in multi-arg case) and upvar (e.g., made silent TCL_ERROR for invalid argument arities explicit) have been fixed. * Object.man, methods.test: Added documentation for both methods (Object.man) and tests.

  1. … 7 more files in changeset.
added an additional variant of ALLOC_ON_STACK

The new version does not use alloca(), it does not use VLA

and it does not boat the stack in case huge vectors are to be processed.

It uses a plain array up to a certain size and switches to malloc()

above this size.

- improved error message "not allowed to have default": make clear, this is from a parameter specification - added object property "autonamed" (set automatically for objects created via "new") - xotcl2 volatile: improved backward compatibility with XOTcl 1 - extended regression test

  1. … 4 more files in changeset.
* nsf.c, nsfShadow.c (NsfProcStubDeleteProc, Nsf_RenameObjCmd): Provide for coupled renaming of the nsf::proc pairs; and coupled deletion.

  1. … 3 more files in changeset.
* nsf.c, nsfInt.h (NsfProcStub, NsfProcClientData): Apply namespace reform to nsf::procs, to prevent proc redefinition after a proc rename to fail. * nsf-cmd.test: Add test case to document/ to cover failing rename + redefine.

  1. … 2 more files in changeset.
improve handling of HAVE_INTTYPES_H under windows

  1. … 1 more file in changeset.
guard definition of PRIxPTR by HAVE_INTTYPES_H and not by HAVE_STDINT_H

improve type cleanness

  1. … 1 more file in changeset.
updates of annouce file, tested with mongo-c-dirver 1.12.0 (released yesterday)

  1. … 6 more files in changeset.
* nsfDebug.c, nsfInt.h (STRING_NEW, MEM_COUNT_ALLOC, MEM_COUNT_FREE): Fix compilation with --enable-memcount=yes.

  1. … 1 more file in changeset.
* nsfInt.h (STRING_NEW): Silence GCC 8.1 warnings on truncation risk using strncpy; made me wonder whether STRING_NEW would not be more robust against mis-computations of the destination-buffer length by using snprintf (mainly because snprintf does not nul-pad the destination buffer and always nul-terminates the destination buffer)?

* nsf.c (ParamOptionParse), nsfInt.h: Provide for own MAX and MIN macros, the ones reused implicitly from Tcl's tommath have vanished in 8.7 branches; and are not provided otherwise, at least in MinGW settings. Fixes 8.7 builds for MinGW under Win.

  1. … 1 more file in changeset.
* nsf.c (ListMethod): Provide a disassemble implementation based on ::tcl::unsupported::disassemble. [::nsf::cmf::info disassemble] is generally available, the info ?object? method variants only in development mode. Implementation covers proc methods and ::nsf::procs. Along the way, prettify some code paths in ListMethod.
