  • finding changes in tcl8.7?

    From Ralf Fassel@21:1/5 to All on Wed Jun 15 18:00:21 2022
    Triggered by yesterdays' virtual meetup I took a chance on recompiling
    our code base against tcl8.7a5. Compilation succeeded with minor
    changes in some outdated packages (eg still using CONST84 macro which
    seems no longer available in 8.7).

    Now I'm facing some problems when running the resulting programs.
    In order to research these I'm wondering what is the best way to search
    for recent changes in tcl8.7 vs tcl8.6.

    In the good old ages there were the Changelog files, which are no longer maintained. Searching the timeline on https://core.tcl-lang.org/ either returns tons of unrelated results, or none at all.

    Eg. I have the problem with old Tix using

    global tkPriv
    if {![llength [info globals tkPriv]]} {
    tk::unsupported::ExposePrivateVariable tkPriv
    }

    resulting in

    invalid command name "tk::unsupported::ExposePrivateVariable"
    while executing
    "tk::unsupported::ExposePrivateVariable tkPriv"
    (file "/homes/ralf/si++aegis/si++.4.0.C716/tcltk/linux/lib64/Tix8.4.3/ComboBox.tcl" line 20)
    invoked from within
    "source /homes/ralf/si++aegis/si++.4.0.C716/tcltk/linux/lib64/Tix8.4.3/ComboBox.tcl"


    Now I wanted to check what happened to either 'tkPriv' (1000+ results)
    or "tk::unsupported::ExposePrivateVariable" (1 result which added the
    function in 2001, but none about removal).

    So: how do I find which check-in affected a specific part of Tcl/Tk?

    Thanks

    | Great ! But as tcl8.7a5 is also quite outdated, it would be great to
    | test against core-8-branch (tcl) and main (tk). Or better main branch
    | in both of them.

    Ah, ok. I just took what was linked on https://www.tcl-lang.org/ which
    leads to https://www.tcl-lang.org/software/tcltk/8.7.html which has a
    big "DOWNLOAD SOURCES" link - zu verführerisch :-)

    Will retry with latest main branch for Tcl and Tk.

    My main issue seems related to the changes due to having all the Tcl/Tk
    init startup code in zipfs, plus some issues relating to TCL_LIBRARY environment variables which we required up to 8.6, but these seem no
    longer required in 8.7. Stay tuned :-)

    Hi Ralf,

    Tix does work with Tcl/Tk 8.7.a5 using my BAWT framework.
    But I disable zipfs using "--disable-zipfs" when compiling Tcl and Tk.

    Thanks, Paul!

    In the meantime I got it compiling and running with ZIPFS (which I like
    to have in the core :-).

    The main issue was
    a) setting TCL_LIBRARY/TK_LIBRARY in the environment (left-over from
    ancient times tcl 8.3, don't ask), and
    b) overriding auto_path in our startup instead of appending to it:

    set auto_path [list \
    $env(TCL_LIBRARY) \
    $env(TK_LIBRARY) \
    [our libs go here]]

    instead of leaving the TCL stuff to tcl, and just appending our stuff

    lappend auto_path [our libs go here]

    Regression tests are running right now :-)
