[ruby-core:65925] [ruby-trunk - Bug #10416] Create mechanism for updating of Unicode data files downstreams when we want

From: naruse@...

Issue #10416 has been updated by Yui NARUSE.


For years, file structures of Unicode Data was changed some times.
Therefore there's no guarantee that Unicode 12 can work with the current sc=
ript.

Bug #10416: Create mechanism for updating of Unicode data files downstreams=
 when we want
https://bugs.ruby-lang.org/issues/10416#change-49663

* Author: Martin D=C3=BCrst
* Status: Open
* Priority: Normal
* Assignee: Nobuyoshi Nakada
* Category: build
* Target version: current: 2.2.0
* ruby -v: ruby 2.2.0dev (2014-10-22 trunk 48092) [x86_64-cygwin]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
The current mechanism for updating Unicode data files will create the follo=
wing problem:
Downstream compilers/packagers will download Unicode data files ONE time (t=
hey may already have done so).

However, if they don't activate ALWAYS_UPDATE_UNICODE =3D yes, these files =
will never get updated, and they will stay on Unicode version 7.0 even if i=
n five years Unicode is e.g. on version 12.0.
On the other hand, if they activate ALWAYS_UPDATE_UNICODE =3D yes (and assu=
ming issue #10415 gets fixed), they constantly update to the latest version=
 of Unicode. That's good for those who actually want this, but now what our=
 current policy is.
What's missing is that we (Ruby core) can make sure downstream checkouts up=
date to a new Unicode version when we want then to do so (as we e.g. can do=
 for other parts that are based on Unicode data, see e.g. https://bugs.ruby=
-lang.org/issues/9092), without sending an email to everybody and hoping th=
ey read and follow it.

[Currently, the only solution I know will work is the one pointed out by Yu=
i Naruse in https://bugs.ruby-lang.org/issues/10084#note-17, but I'm okay w=
ith any other solution.]
