2. Project Summary
2.1. Project Description:
Update the version of Perl shipped with Solaris to the latest
available
version.
2.2. Risks and Assumptions:
This case is a direct follow-on from the following cases:
PSARC/1999/192 Including Perl 5 with Solaris
PSARC/2001/145 Update of Perl shipped with Solaris to version 5.6.1
PSARC/2003/661 Update Perl to version 5.8.x
PSARC 2005/462 Removal of Perl 5.6.1 from Solaris 11
Perl 5.005_03 (introduced in Solaris 8 by PSARC/1999/192) was
declared
EOF in Solaris 9, and was removed earlier in the development of
Solaris
10. Perl 5.6 was declared EOF in Solaris 10, and was removed from
OpenSolaris. This fast-track intends to integrate the latest
version of
the Perl 5.10.x chain into OpenSolaris.
Perl 5.10.x is binary-incompatible with 5.8.x, so it will be
necessary
to declare 5.8.x EOF in OpenSolaris, and remove it in a later
version.
A separate case will be submitted for this.
Unlike previous releases, 5.10.x will not integrate in to O/N, but
will instead move to SFW.
3. Business Summary
3.1. Problem Area:
Perl is a very commonly-used tool, and is used to deliver Solaris
functionality (kstat(1M), projadd(1M), projdel(1m) etc.), it is
used by
the Apache we ship with Solaris and it is used by several unbundled
tools (e.g. SunCluster)
3.2. Market/Requester:
A complete cross-section of customers use Perl.
3.3. Business Justification:
We need to keep OSS tools that we include in Solaris up-to-date in
order to maintain credibility and avoid support costs for bugs
in the
older versions that are fixed by later versions
3.4. Competitive Analysis:
Most other competing products either include Perl as standard or
make
it readily available.
3.5. Opportunity Window/Exposure:
Need to have an up-to-date version of Perl in OpenSolaris
3.6. How will you know when you are done?:
Perl test suite passes all tests, existing Solaris commands
continue to
work correctly with the new version.
4. Technical Description:
4.1. Details:
The standard perl 5.10.x distribution will be obtained from the perl
source archive (http://cpan.org/src), unnecessary components will
be removed (e.g. support for other Operating Systems) and the source
files will be integrated into SFW.
If any bugs are encountered during the integration, these will
be fixed
and submitted for integration into the Perl repository, so that they
will be hopefully automatically included in a future version.
The fix
will then be included in the perl SFW code via a patch, and the
output
of 'perl -V' modified to reflect the change.
4.2. Bug/RFE Number(s):
RFE: #6841312
OSR ID# 11317
4.3. In Scope:
See above.
4.4. Out of Scope:
See above.
4.5. Interfaces:
Following the interface stability section of the perl(1)
manpage, here
is the impact of this upgrade on the various Perl interfaces:
Script interface (Uncommitted)
---------------------------
There have been no major changes between 5.8.x and 5.10.x
except
backwards compatible extensions.
Incompatible changes are as follows:
* Packing and UTF-8 strings
* Byte/character count feature in unpack()
* The $* and $# variables have been removed
* substr() lvalues are no longer fixed-length
* Parsing of -f _
* :unique
* Effect of pragmas in eval
* chdir FOO
* Handling of .pmc files
* $^V is now a version object instead of a v-string
* @- and @+ in patterns
* $AUTOLOAD can now be tainted
* Tainting and printf
* undef and signal handlers
* strictures and dereferencing in defined()
* (?p{}) has been removed
* Pseudo-hashes have been removed
* Removal of the bytecode compiler and of perlcc
* Removal of the JPL
* Recursive inheritance detected earlier
Full explanation of changes are included in
perl5100delta.pod.txt
(in the case materials directory)
XSUB interface (Uncommitted)
-------------------------
There have been no major changes since 5.8.x
Binary interface (Uncommitted)
---------------------------
Perl 5.10.x is not binary-compatible with 5.8.x.
XS modules will require recompilation.
