Re: [gentoo-user] Perl 5.26 Unmasking Warning [affects all users]

[Kent Fredric]

As advised in the previous email[1], Perl 5.26.1 is scheduled to be
unmasked and available to ~arch come October 7th.

All the major blockers of known serious defects are fixed[2], but
there's still quite a number of lower-severity issues that are still
yet to be addressed[3]

Stabilization of Perl 5.24.3 will kick off from maintainer side around
the same time.

If you have not yet read the previous email[1] and decided if you need
to react to it or not, now would be a good time.

[gentoo-user] Perl 5.26 Unmasking Warning [affects all users]

[Kent Fredric]

We're finally at a point where we're nearing the unmasking[1] of Perl
5.26 and making it visible to ~arch users, and a "news item" on this
matter will appear shortly.

Due to a collection of various problems faced in this version,
extensive amounts of work has been needed to simply deliver an ~arch
release that isn't incredibly visibly broken [1][2].

Subsequently, this will require a lot of care from end users who use
~arch versions of Perl, specifically as breakages manifest all over the
tree, in places you wouldn't expect ( for example: make, automake,
autoconf, gcc, and even some python packages have been broken by
changes in this release )

If you use Gentoo as a production server, this will be a good time to
set aside a seperate box for testing the side effects of this release
on your platform, and you should assume this release *will* affect you
in some way.

There are 4 Major types of failures [3]:

1: [build] failiures related to the removal of '.' from @INC [4] such 
as:
 - Can't locate inc:: ... in @INC (you may need to install the ... module)
 - Can't locate t:: ... in @INC (you may need to install the ... module)
 - do "foo.pl" failed, '.' is no longer in @INC; did you mean do "./foo.pl"?

2: [buildtime] The default of internal OP OP_SIBLING/OP_PARENT changing:
 - error: ... has no member named ‘op_sibling'
 
3: [runtime] Unescaped "{" in regex becomming a fatal error:
 - Unescaped left brace in regex is illegal in ...

4: [runtime] The removal of POSIX::tmpname in favour of File::Temp
 - Unimplemented: POSIX::tmpnam()

Our hope is to have all the in-tree bugs [5] fixed long in advance of
needing to stabilize Perl 5.26.

However, special efforts will have to be added for anything using an
overlay, and any of your private code ( such as things you've manually
installed into /opt  or /usr/local/ ) will need additional care as
these are outside the visibility of Gentoo Devs.

Please make sure to report any bugs you find that are clearly caused by
Perl 5.26 ( of course, first skim the lengthy list of known issues for
duplicates [6] ).
