[Shubham Chakraborty]

Major version upgrade from 8.6 to 9.0 series.

Key changes in Tcl 9.0:
- Full Unicode support (UTF-16/UTF-32/UCS-2 encodings)
- 64-bit integer support
- Enhanced encoding with -profile/-failindex options
- Script library packaged with binary
- Improved virtual filesystem support

Also remove bundled itcl and thread packages to reduce bloat.

Where is this list of key changes coming from? It doesn't match with
what is at https://www.tcl-lang.org/software/tcltk/9.0.html. Is this
just AI-generated slop?

> Also remove bundled itcl and thread packages to reduce bloat.

And this will not break existing users? Is it because those packages
are new?

[Buildroot] [PATCH v2] package/tcl: bump to version 9.0.3

[Shubham Chakraborty]

Bump the version of tcl to 9.0.3. This is a major version upgrade
from 8.6 to 9.0 series.

Notable changes in Tcl 9.0 include:
 - 64-bit Capacity: Data values larger than 2Gb
 - Unicode and Encodings: full codepoint range, added encodings,
   encoding profiles to govern I/O, and more.
 - Zip Filesystems: mount zipfiles as filesystems
 - Attached Archives: enable starkit-style deployment of apps,
   with support data in filesystem archives attached to executable
   or libraries. Build tclsh and wish this way.
 - New Notifiers: The central event handling engine in Tcl is now
   constructed on top of the system calls epoll or kqueue when they
   are available. The select based implementation also remains for
   platforms where they are not.

Build / Cross-compilation fixes for Tcl 9.0 ZipFS:
 - In Tcl 9.0, Zip virtual filesystems (ZipFS) are built into the core
   package and bundled packages (itcl, thread). Generating these zip
   archives during cross-compilation requires running a native tclsh.
 - Add host-tcl to TCL_DEPENDENCIES and add a HOST_TCL_SYMLINK_TCLSH
   hook so $(HOST_DIR)/bin/tclsh is available.
 - Pass TCLSH and TCLSH_PROG explicitly in TCL_MAKE_OPTS pointing to
   $(HOST_DIR)/bin/tclsh$(TCL_VERSION_MAJOR) to ensure sub-Makefiles
   use the native host interpreter without inheriting target
   LD_LIBRARY_PATH settings.

Note on bundled packages:
Unlike v1, we do not remove the bundled itcl (Incr Tcl) and thread
packages. These packages were already present in 8.6 and built by
default. Removing them in Tcl 9.0 would break compatibility for existing
runtime scripts relying on them (Buildroot has no standalone packages for
them).

More Details & Changelogs:
 - https://www.tcl-lang.org/software/tcltk/9.0.html

Tested using:
 utils/test-pkg -a -c /tmp/tcl.config -p tcl
 (Result: 32 builds, 4 skipped, 0 build failed)

Changes v1 -> v2:
  - Reverted removal of bundled 'itcl' and 'thread' packages to prevent
    breaking runtime scripts relying on them.
  - Rewrote commit message highlights to accurately match official Tcl 9.0
    release notes at https://www.tcl-lang.org/software/tcltk/9.0.html.
  - Added explicit note on bundled packages rationale in commit body.
  - Added host-tcl dependency and host tclsh symlink to fix ZipFS build
    failures during cross-compilation.
  - Overrode TCLSH and TCLSH_PROG in TCL_MAKE_OPTS to prevent
    LD_LIBRARY_PATH pollution during cross-compilation.
  - Ran full 32-toolchain test matrix via test-pkg -a (28 builds OK, 4 skipped, 0 failed).

Are you sure you need to symlink, since...

> +	TCLSH_PROG="$(HOST_DIR)/bin/tclsh$(TCL_VERSION_MAJOR)"

... you're passing the full path to
$(HOST_DIR)/bin/tclsh$(TCL_VERSION_MAJOR) here?

From my quick experiment, it seems like the symlink is not needed.

Also, could you verify that both TCLSH= and TCLSH_PROG= are needed?

With your patch:

- host-tcl fails to build because <zlib.h> is not found. Seems like
  host-zlib is now needed as a dependency of host-tcl. Make sure to
  build in a minimal Docker container to figure out this kind of
  issue. You can trivially do that in Buildroot: "./utils/docker-run
  make".

- tcllib fails to build, because version 1.21 is not designed to work
  with Tcl 9.0, you need to bump tcllib to 2.0 apparently.

Could you look into these different issues, and get back to us with an
updated patch?

Thanks a lot!

Thomas
