We're finally at a point where we're nearing the unmasking[1] of Perl |
| 2 |
5.26 and making it visible to ~arch users, and a "news item" on this |
| 3 |
matter will appear shortly. |
| 4 |
|
| 5 |
Due to a collection of various problems faced in this version, |
| 6 |
extensive amounts of work has been needed to simply deliver an ~arch |
| 7 |
release that isn't incredibly visibly broken [1][2]. |
| 8 |
|
| 9 |
Subsequently, this will require a lot of care from end users who use |
| 10 |
~arch versions of Perl, specifically as breakages manifest all over the |
| 11 |
tree, in places you wouldn't expect ( for example: make, automake, |
| 12 |
autoconf, gcc, and even some python packages have been broken by |
| 13 |
changes in this release ) |
| 14 |
|
| 15 |
If you use Gentoo as a production server, this will be a good time to |
| 16 |
set aside a seperate box for testing the side effects of this release |
| 17 |
on your platform, and you should assume this release *will* affect you |
| 18 |
in some way. |
| 19 |
|
| 20 |
There are 4 Major types of failures [3]: |
| 21 |
|
| 22 |
1: [build&runtime] failiures related to the removal of '.' from @INC [4] such as: |
| 23 |
- Can't locate inc:: ... in @INC (you may need to install the ... module) |
| 24 |
- Can't locate t:: ... in @INC (you may need to install the ... module) |
| 25 |
- do "foo.pl" failed, '.' is no longer in @INC; did you mean do "./foo.pl"? |
| 26 |
|
| 27 |
2: [buildtime] The default of internal OP OP_SIBLING/OP_PARENT changing: |
| 28 |
- error: ... has no member named ‘op_sibling' |
| 29 |
|
| 30 |
3: [runtime] Unescaped "{" in regex becomming a fatal error: |
| 31 |
- Unescaped left brace in regex is illegal in ... |
| 32 |
|
| 33 |
4: [runtime] The removal of POSIX::tmpname in favour of File::Temp |
| 34 |
- Unimplemented: POSIX::tmpnam() |
| 35 |
|
| 36 |
Our hope is to have all the in-tree bugs [5] fixed long in advance of |
| 37 |
needing to stabilize Perl 5.26. |
| 38 |
|
| 39 |
However, special efforts will have to be added for anything using an |
| 40 |
overlay, and any of your private code ( such as things you've manually |
| 41 |
installed into /opt or /usr/local/ ) will need additional care as |
| 42 |
these are outside the visibility of Gentoo Devs. |
| 43 |
|
| 44 |
Please make sure to report any bugs you find that are clearly caused by |
| 45 |
Perl 5.26 ( of course, first skim the lengthy list of known issues for |
| 46 |
duplicates [6] ). |
