1407 | C<Configure> will now detect C<clearenv> and C<unsetenv>, thanks to a patch
|
---|
1408 | from Alan Burlison. It will also probe for C<futimes> and whether C<sprintf>
|
---|
1409 | correctly returns the length of the formatted string, which will both be used
|
---|
1410 | in perl 5.8.9.
|
---|
1411 |
|
---|
1412 | There are improved hints for next-3.0, vmesa, IX, Darwin, Solaris, Linux,
|
---|
1413 | DEC/OSF, HP-UX and MPE/iX

1414 |
|

1415 | Perl extensions on Windows now can be statically built into the Perl DLL,
|
---|
1416 | thanks to a work by Vadim Konovalov. (This improvement was actually in 5.8.7,
|
---|
1417 | but was accidentally omitted from L<perl587delta>).

1419 | =head1 Selected Bug Fixes
|
---|
1420 |
|
---|
1421 | =head2 no warnings 'category' works correctly with -w
|
---|
1422 |
|
---|
1423 | Previously when running with warnings enabled globally via C<-w>, selective
|
---|
1424 | disabling of specific warning categories would actually turn off all warnings.
|
---|
1425 | This is now fixed; now C<no warnings 'io';> will only turn off warnings in the
|
---|
1426 | C<io> class. Previously it would erroneously turn off all warnings.
|
---|
1427 |
|
---|
1428 | This bug fix may cause some programs to start correctly issuing warnings.
|
---|
1429 |
|
---|
1430 | =head2 Remove over-optimisation
|
---|
1431 |
|
---|
1432 | Perl 5.8.4 introduced a change so that assignments of C<undef> to a
|
---|
1433 | scalar, or of an empty list to an array or a hash, were optimised away. As
|
---|
1434 | this could cause problems when C<goto> jumps were involved, this change
|
---|
1435 | has been backed out.
|
---|
1436 |
|
---|
1437 | =head2 sprintf() fixes
|
---|
1438 |
|
---|
1439 | Using the sprintf() function with some formats could lead to a buffer
|
---|
1440 | overflow in some specific cases. This has been fixed, along with several
|
---|
1441 | other bugs, notably in bounds checking.
|
---|
1442 |
|
---|
1443 | In related fixes, it was possible for badly written code that did not follow
|
---|
1444 | the documentation of C<Sys::Syslog> to have formatting vulnerabilities.
|
---|
1445 | C<Sys::Syslog> has been changed to protect people from poor quality third
|
---|
1446 | party code.
|
---|
1447 |
|
---|
1448 | =head2 Debugger and Unicode slowdown
|
---|
1449 |
|
---|
1450 | It had been reported that running under perl's debugger when processing
|
---|
1451 | Unicode data could cause unexpectedly large slowdowns. The most likely cause
|
---|
1452 | of this was identified and fixed by Nicholas Clark.
|
---|

|

1528 |

1529 | This is a new warning, produced in situations such as this:
|
---|
1530 |
|
---|
1531 | $r = do {my @a; \$#a};
|
---|
1532 | $$r = 503;

1533 |
|
---|
1534 | =head2 Non-string passed as bitmask
|
---|
1535 |
|
---|
1536 | This is a new warning, produced when number has been passed as a argument to
|
---|
1537 | select(), instead of a bitmask.
|
---|
1538 |
|
---|
1539 | # Wrong, will now warn

1548 | =head2 Search pattern not terminated or ternary operator parsed as search pattern
|

1549 |

1550 | This syntax error indicates that the lexer couldn't find the final

1551 | delimiter of a C<?PATTERN?> construct. Mentioning the ternary operator in
|
---|
1552 | this error message makes it easier to diagnose syntax errors.
|
---|
1553 |
|
---|
1554 | =head1 Changed Internals
|
---|
1555 |
|
---|
1556 | There has been a fair amount of refactoring of the C<C> source code, partly to
|
---|
1557 | make it tidier and more maintainable. The resulting object code and the
|
---|
1558 | C<perl> binary may well be smaller than 5.8.7, in particular due to a change
|
---|
1559 | contributed by Dave Mitchell which reworked the warnings code to be
|
---|
1560 | significantly smaller. Apart from being smaller and possibly faster, there
|
---|
1561 | should be no user-detectable changes.
|
---|
1562 |
|
---|
1563 | Andy Lester supplied many improvements to determine which function
|
---|
1564 | parameters and local variables could actually be declared C<const> to the C
|
---|
1565 | compiler. Steve Peters provided new C<*_set> macros and reworked the core to
|
---|
1566 | use these rather than assigning to macros in LVALUE context.
|
---|
1567 |
|
---|
1568 | Dave Mitchell improved the lexer debugging output under C<-DT>
|
---|
1569 |
|
---|
1570 | Nicholas Clark changed the string buffer allocation so that it is now rounded
|
---|
1571 | up to the next multiple of 4 (or 8 on platforms with 64 bit pointers). This
|
---|
1572 | should reduce the number of calls to C<realloc> without actually using any
|
---|
1573 | extra memory.
|
---|
1574 |
|
---|
1575 | The C<HV>'s array of C<HE*>s is now allocated at the correct (minimal) size,
|
---|
1576 | thanks to another change by Nicholas Clark. Compile with
|
---|
1577 | C<-DPERL_USE_LARGE_HV_ALLOC> to use the old, sloppier, default.
|
---|
1578 |
|
---|
1579 | For XS or embedding debugging purposes, if perl is compiled with
|
---|
1580 | C<-DDEBUG_LEAKING_SCALARS_FORK_DUMP> in addition to
|
---|
1581 | C<-DDEBUG_LEAKING_SCALARS> then a child process is C<fork>ed just before
|
---|
1582 | global destruction, which is used to display the values of any scalars
|
---|
1583 | found to have leaked at the end of global destruction. Without this, the
|
---|
1584 | scalars have already been freed sufficiently at the point of detection that
|
---|
1585 | it is impossible to produce any meaningful dump of their contents. This
|
---|
1586 | feature was implemented by the indefatigable Nicholas Clark, based on an idea
|
---|
1587 | by Mike Giroux.

1589 | =head1 Platform Specific Problems
|
---|
1590 |
|
---|
1591 | The optimiser on HP-UX 11.23 (Itanium 2) is currently partly disabled (scaled
|
---|
1592 | down to +O1) when using HP C-ANSI-C; the cause of problems at higher
|
---|
1593 | optimisation levels is still unclear.
|
---|
1594 |
|
---|
1595 | There are a handful of remaining test failures on VMS, mostly due to
|
---|
1596 | test fixes and minor module tweaks with too many dependencies to
|
---|
1597 | integrate into this release from the development stream, where they have
|
---|
1598 | all been corrected. The following is a list of expected failures with
|
---|
1599 | the patch number of the fix where that is known:

1609 |
|

1610 | If you find what you think is a bug, you might check the articles
|
---|
1611 | recently posted to the comp.lang.perl.misc newsgroup and the perl
|
---|
1612 | bug database at http://bugs.perl.org. There may also be
|
---|
1613 | information at http://www.perl.org, the Perl Home Page.
|
---|
1614 |
|
---|
1615 | If you believe you have an unreported bug, please run the B<perlbug>
|
---|
1616 | program included with your release. Be sure to trim your bug down
|
---|
1617 | to a tiny but sufficient test case. Your bug report, along with the
|
---|
1618 | output of C<perl -V>, will be sent off to [email protected] to be
|
---|
1619 | analysed by the Perl porting team. You can browse and search
