Porting extensions to Tcl 9

PO - Update on 2024-07-09 incorporating remarks and comments.

This page is the summary of my experiences trying to port the Tcl packages or programs supported by BAWT to Tcl9.

The following Tcl and Tk versions have been used for the porting tests:

Tcl9.0b2	9.0b2+3266fc297b4ae23ee1ddffb7fe35c1ede4939efc774f46d7d6378083842d1d15.gcc-702
Tk9.0b2	9.0b2+58f75f997e2e1438a8f04978c3c8c0f21e4bbd88bbff83680149ad4553f00c44.gcc-702.win32

Table Packages lists all packages looked at and their current status.
Table Changes in Tcl summarizes all changes done at the Tcl level for all packages.
Table Changes in C summarizes all changes done at the C level for all packages.
All other tables summarize the changes done for each individual package or program.

The tables below are based on the following Excel file: https://www.tcl3d.org/bawt/download/Tcl9-Port.xlsx

Please feel free to add your experiences, additions and comments.

Packages

This table summarizes the status of the package ports.

The columns show the folllowing information:

Package: The name and a link to the package home page.
Start version: The version number and a link to the source of the package as used for start of the porting or the working Tcl 9 version.
Ported version: The version number and a link to the source of the ported package. If entry is Works, then the Start version is working. If entry is NoTcl9, I either did not look at the package or it was too much effort.
Build: The modified package could be compiled with Tcl 9.
Require: A package require suceeded for the package with Tcl 9.
Bawt Test: The simple BAWT test program for this package works with Tcl 9.
Responsible: The name or link of the package maintainer.
Active Tcl9 Development: Flag indicating active Tcl9 development.
Comments: Short comments regarding this package. Add longer comments at the end of the table.

Note, that the ported versions also work with Tcl/Tk 8.6.14 and 8.7.b1.

Changes in Tcl

This table summarizes the changes done for porting Tcl programs.

Some of the actions are described first as code examples.

Replaced package require Tcl 8.X with package require Tcl 8.X-

Replaced package require Tk 8.X with package require Tk 8.X-

An alternative to the above is as follows:

AK While going from 8.X to 8.X- opens the package to 9, it also opens it to 10, 11, etc. A more restricted way would be to go to package require Tcl 8.X 9. The two requirements, 8.X, and 9 are OR-ed. The command accepts the Tcl version, if it matches at least one of the requirements. With this change the package is opened to 9, but not beyond.

Common changes in Tcl files	Comments
Replaced $tcl_platform with $::tcl_platform in namespaces
Replaced package require Tcl 8.X with package require Tcl 8.X-
Replaced package require Tk 8.X with package require Tk 8.X-
Replaced package vsatisfies Tcl 8.X with package vsatisfies Tcl 8.X-
Added string totitle in pkgIndex.tcl.in or pkgIndex.tcl
Added string totitle in Makefile.in
Replaced "~" with file tildeexpand "~" for Tcl >= 9
Replaced obsolete case command with switch
Use source -encoding utf-8 instead of plain source
Changed functionality: ttk::combobox::current returns empty string instead of -1
Check for octal numbers.

Changes in C

This table summarizes the changes done for porting C/C++ extensions.

Some of the actions are described first as code examples.

Added Tcl_Size related definitions, if TCL_SIZE_MAX is not defined

/* Check, if Tcl version supports Tcl_Size,
   which was introduced in Tcl 8.7 and 9.
*/
#ifndef TCL_SIZE_MAX
    #include <limits.h>
    #define TCL_SIZE_MAX INT_MAX

    #ifndef Tcl_Size
        typedef int Tcl_Size;
    #endif

    #define TCL_SIZE_MODIFIER ""
    #define Tcl_GetSizeIntFromObj Tcl_GetIntFromObj
#endif

Replaced Tcl_SavedResult, Tcl_DiscardResult, Tcl_SaveResult, Tcl_RestoreResult with Tcl9 functions

DKF: Note that Tcl_SaveResult() has basically been deprecated since Tcl 8.5 because it doesn't handle the full state of the interpreter (and can't; not enough space in the Tcl_SavedResult structure definition and that's caller allocated; by comparison, Tcl_InterpState is an opaque handle and has its definition entirely managed by Tcl's internals). Unless you need the code to still work in Tcl 8.4 and before, you should update to use the new API. Tcl 9 just removes that deprecated API. Tcl 8.5 and 8.6 were the transition period (over a decade).

#if TCL_MAJOR_VERSION < 9
    Tcl_SavedResult savedResult;
#else
    Tcl_InterpState savedResult;
#endif

#if TCL_MAJOR_VERSION < 9
    Tcl_SaveResult(interp, &savedResult);
#else
    savedResult = Tcl_SaveInterpState(interp, TCL_OK);
#endif

#if TCL_MAJOR_VERSION < 9
    Tcl_RestoreResult(interp, &savedResult);
#else
    Tcl_RestoreInterpState(interp, savedResult);
#endif

#if TCL_MAJOR_VERSION < 9
    Tcl_DiscardResult(&state);
#else
    Tcl_DiscardInterpState(state);
#endif

Replaced Tcl_PanicVA with `Tcl_Panic using method described in TIP 422
Replaced panic with Tcl_Panic
Replaced Tcl_DriverCloseProc with Tcl_DriverClose2Proc. Changed signature of corresponding function.

Removed expressions using obsolete TCL_INTERP_DESTROYED	DGP: Any code still making use of the TCL_INTERP_DESTROYED flag should be converted to call the Tcl_InterpDeleted routine.
Removed expressions using obsolete TCL_PARSE_PART1	DGP: The last Tcl release where the TCL_PARSE_PART1 flag had any effect was Tcl 8.0. Just remove it.
Removed expressions using obsolete TK_CONFIG_OPTION_SPECIFIED
Replaced obsolete TCL_OUT_LINE_COMPILE with TCL_ERROR
Replaced obsolete TK_X_EVENTS with TCL_WINDOW_EVENTS
Replaced obsolete TK_DONT_WAIT with TCL_DONT_WAIT
Replaced Tcl_SavedResult, Tcl_DiscardResult, Tcl_SaveResult, Tcl_RestoreResult with Tcl9 functions

Updated tclconfig files
Updated files config.guess and config.sub

Added Tcl_Size related definitions, if TCL_SIZE_MAX is not defined
Replaced ìnt with Tcl_Size in functions having Tcl_Size as output parameter
Replaced NULL or 0 with (Tcl_Size *)NULL in functions having Tcl_Size as input parameter
Replaced NULL with (char *)NULL in calls of function Tcl_AppendResult or Tcl_SetErrorCode	chrstphrchvz: Note that casting the NULL sentinel is not for Tcl 9 readiness, but rather something that should be done anyway for portability.
