Re: [platform-dev] SWT - supported Linux versions

["Gregor Schmid" <gschmide@xxxxxx>]

Hi all,

the number 4.940 in version.txt has only just become meaningless - see
the recent discussion about "Inconsistent version change in SWT 4.18"
and the associated closed bug report

https://bugs.eclipse.org/bugs/show_bug.cgi?id=567789

In that discussion Tom mentioned the Manifest file as an alternative
and I'm investigating that. Thanks Aleksandar, for moving that
forward.

So I'm also curious about the Implementation-Version in the Manifest
file. Does that have a well-defined meaning? Is it documented
somewhere? Is it reliable?

If not, wouldn't it be a good idea to have both "4.18" and "2020-12"
added to the Manifest file and/or as constants at some well-defined
location like the Library class or the version.txt file?

My suggestion to use a map to deduct the user-visible version from
whatever inconsistent version number is embedded in the code was
actually a joke. If that's the only way, so be it, but from a software
engineering standpoint I still vote for something predictable :-).

Best regards,
    Greg
