[TCLCORE] Report of BiWeekly Tcl/Tk conference

[Harald O. <har...@el...>]

Dear TCL/Tk team,
thanks for the great meeting today. Here is a report.

1) celebrate great TCL/Tk 8.6.16 release !
2) upcomming TCL/Tk 9.0.1 release
2.1) changes.md update -> TIP 707 is not mentioned as it is internal change
-> Ashok adds TIP707

2.2) DKF's Enum work: is it ok on main and for 9.0.1. Should rewrites 
like this merged to 9.1 (when development branch open)?
https://core.tcl-lang.org/tcl/info/5611b610925a7a30

-> Cosmetic change, easy to get typing errors in
-> Jan has tested and approved it for 9.0.1
-> Those cosmetic changes:
   - should first go into a branch for a 2nd eye (risk of error)
   - should not be done just before a release
Result: go to 9.0.1

2.3) namespace children subnamespace does not match exactly
https://core.tcl-lang.org/tcl/info/63449c0514
It fixes a real problem. But the fix feels critical as not fully 
understood. Nevertheless, a fix is a fix -> go to 9.0.1

2.4) zip bundling - ticket aaa84fbb -> eventual user guidance?
-> User guidense difficult as many combination possible

2.5) git/fossil checkin in build-info - tclUuid.h -> eventual user guidance?
-> all useful files are committed

2.6) bundled packages state: ITCL, Thread, TDBC
-> SQLite patches by Jan get partly upstream
-> may add a warning that ITCL may be unbundled-> ask community about use
-> ITCL will break with 9.1 with the long command argument TIP.
2.7) Install/compile/package TCL 8.6 and 9.0 together/on same computer 
-> eventual user guidance?
-> 8.6,8.7 and 9.0 runs from the same directory.
-> development packages (tcl.h) are distinct.
-> man pages are distinct-> Torsten
-> nothing new with TCL8.5/8.6: but did not ship together.

2.8) Include recent Thread package bug fix in 9.0.1
https://core.tcl-lang.org/thread/info/f32864af

3) TIP 705 Licence
Vote is pending and expected for next year

4) Tk image copy performance  [e7fc29ce]: image copy optimization: test 
for alpha != 0/1 takes more time, than it optimizes.
Paul just remarks it but has no confidence in his patch. Only a branch 
and experimentation may show issues.

5) Renés Tk bindings proposals
Thanks for the core list message. This great input should not be lost, 
but is not for 9.0.1.
-> selection improvements: type beginning of a text to select -> 
requires a TIP to explain
-> bindings may conflict with user choice -> Tk 9.1.
-> or TkLib

Thanks for all ! Remark that the next meeting is in one week: 20th of 
December 12:00 UTC.

Take care,
Harald
