| 1382 | Weak reference creation is now I<O(1)> rather than I<O(n)>, courtesy of |
| 1383 | Nicholas Clark. Weak reference deletion remains I<O(n)>, but if deletion only |
| 1384 | happens at program exit, it may be skipped completely. |

| 1393 | Jarkko Hietaniemi and Andy Lester worked to mark as much data as possible in |
| 1394 | the C source files as C<static>, to increase the proportion of the executable |
| 1395 | file that the operating system can share between process, and thus reduce |
| 1396 | real memory usage on multi-user systems. |

| 1399 | |
| 1400 | =head1 Installation and Configuration Improvements |
| 1401 | |
| 1402 | Parallel makes should work properly now, although there may still be problems |
| 1403 | if C<make test> is instructed to run in parallel. |
| 1404 | |
| 1405 | Building with Borland's compilers on Win32 should work more smoothly. In |
| 1406 | particular Steve Hay has worked to side step many warnings emitted by their |
| 1407 | compilers and at least one C compiler internal error. |
| 1408 | |
| 1409 | C<Configure> will now detect C<clearenv> and C<unsetenv>, thanks to a patch |
| 1410 | from Alan Burlison. It will also probe for C<futimes> and whether C<sprintf> |
| 1411 | correctly returns the length of the formatted string, which will both be used |
| 1412 | in perl 5.8.9. |
| 1413 | |
| 1414 | There are improved hints for next-3.0, vmesa, IX, Darwin, Solaris, Linux, |
| 1415 | DEC/OSF, HP-UX and MPE/iX |
| 1416 | |
| 1417 | Perl extensions on Windows now can be statically built into the Perl DLL, |
| 1418 | thanks to a work by Vadim Konovalov. (This improvement was actually in 5.8.7, |
| 1419 | but was accidentally omitted from L<perl587delta>). |
| 1420 | |
| 1421 | =head1 Selected Bug Fixes |
| 1422 | |
| 1423 | =head2 no warnings 'category' works correctly with -w |
| 1424 | |
| 1425 | Previously when running with warnings enabled globally via C<-w>, selective |
| 1426 | disabling of specific warning categories would actually turn off all warnings. |
| 1427 | This is now fixed; now C<no warnings 'io';> will only turn off warnings in the |
| 1428 | C<io> class. Previously it would erroneously turn off all warnings. |
| 1429 | |
| 1430 | This bug fix may cause some programs to start correctly issuing warnings. |
| 1431 | |
| 1432 | =head2 Remove over-optimisation |
| 1433 | |
| 1434 | Perl 5.8.4 introduced a change so that assignments of C<undef> to a |
| 1435 | scalar, or of an empty list to an array or a hash, were optimised away. As |
| 1436 | this could cause problems when C<goto> jumps were involved, this change |
| 1437 | has been backed out. |
| 1438 | |
| 1439 | =head2 sprintf() fixes |
| 1440 | |
| 1441 | Using the sprintf() function with some formats could lead to a buffer |
| 1442 | overflow in some specific cases. This has been fixed, along with several |
| 1443 | other bugs, notably in bounds checking. |
| 1444 | |
| 1445 | In related fixes, it was possible for badly written code that did not follow |
| 1446 | the documentation of C<Sys::Syslog> to have formatting vulnerabilities. |
| 1447 | C<Sys::Syslog> has been changed to protect people from poor quality third |
| 1448 | party code. |
| 1449 | |
| 1450 | =head2 Debugger and Unicode slowdown |
| 1451 | |
| 1452 | It had been reported that running under perl's debugger when processing |
| 1453 | Unicode data could cause unexpectedly large slowdowns. The most likely cause |
| 1454 | of this was identified and fixed by Nicholas Clark. |
| 1455 | |
| 1456 | =head2 Smaller fixes |

| 1462 | C<FindBin> now works better with directories where access rights are more |
| 1463 | restrictive than usual. |
| 1464 | |

| 1466 | |
| 1467 | Several memory leaks in ithreads were closed. An improved implementation of |
| 1468 | C<threads::shared> is available on CPAN - this will be merged into 5.8.9 if |
| 1469 | it proves stable. |
| 1470 | |
| 1471 | =item * |
| 1472 | |
| 1473 | Trailing spaces are now trimmed from C<$!> and C<$^E>. |

| 1476 | |
| 1477 | Operations that require perl to read a process's list of groups, such as reads |
| 1478 | of C<$(> and C<$)>, now dynamically allocate memory rather than using a |
| 1479 | fixed sized array. The fixed size array could cause C stack exhaustion on |
| 1480 | systems configured to use large numbers of groups. |
| 1481 | |
| 1482 | =item * |

| 1488 | You can now use the C<x> operator to repeat a C<qw//> list. This used |

| 1502 | |
| 1503 | The optimisation of C<for (reverse @a)> introduced in perl 5.8.6 could |
| 1504 | misbehave when the array had undefined elements and was used in LVALUE |
| 1505 | context. Dave Mitchell provided a fix. |
| 1506 | |
| 1507 | =item * |
| 1508 | |
| 1509 | Some case insensitive matches between UTF-8 encoded data and 8 bit regexps, |
| 1510 | and vice versa, could give malformed character warnings. These have been |
| 1511 | fixed by Dave Mitchell and Yves Orton. |
| 1512 | |
| 1513 | =item * |
| 1514 | |
| 1515 | C<lcfirst> and C<ucfirst> could corrupt the string for certain cases where |
| 1516 | the length UTF-8 encoding of the string in lower case, upper case or title |
| 1517 | case differed. This was fixed by Nicholas Clark. |
| 1518 | |
| 1519 | =item * |
| 1520 | |
| 1521 | Perl will now use the C library calls C<unsetenv> and C<clearenv> if present |
| 1522 | to delete keys from C<%ENV> and delete C<%ENV> entirely, thanks to a patch |
| 1523 | from Alan Burlison. |

| 1527 | =head1 New or Changed Diagnostics |
| 1528 | |
| 1529 | =head2 Attempt to set length of freed array |
| 1530 | |
| 1531 | This is a new warning, produced in situations such as this: |
| 1532 | |
| 1533 | $r = do {my @a; \$#a}; |
| 1534 | $$r = 503; |
| 1535 | |
| 1536 | =head2 Non-string passed as bitmask |
| 1537 | |
| 1538 | This is a new warning, produced when number has been passed as a argument to |
| 1539 | select(), instead of a bitmask. |
| 1540 | |
| 1541 | # Wrong, will now warn |
| 1542 | $rin = fileno(STDIN); |
| 1543 | ($nfound,$timeleft) = select($rout=$rin, undef, undef, $timeout); |
| 1544 | |
| 1545 | # Should be |
| 1546 | $rin = ''; |
| 1547 | vec($rin,fileno(STDIN),1) = 1; |
| 1548 | ($nfound,$timeleft) = select($rout=$rin, undef, undef, $timeout); |
| 1549 | |
| 1550 | =head2 Search pattern not terminated or ternary operator parsed as search pattern |
| 1551 | |
| 1552 | This syntax error indicates that the lexer couldn't find the final |
| 1553 | delimiter of a C<?PATTERN?> construct. Mentioning the ternary operator in |
| 1554 | this error message makes it easier to diagnose syntax errors. |
| 1555 | |
| 1556 | =head1 Changed Internals |
| 1557 | |
| 1558 | There has been a fair amount of refactoring of the C<C> source code, partly to |
| 1559 | make it tidier and more maintainable. The resulting object code and the |
| 1560 | C<perl> binary may well be smaller than 5.8.7, in particular due to a change |
| 1561 | contributed by Dave Mitchell which reworked the warnings code to be |
| 1562 | significantly smaller. Apart from being smaller and possibly faster, there |
| 1563 | should be no user-detectable changes. |
| 1564 | |
| 1565 | Andy Lester supplied many improvements to determine which function |
| 1566 | parameters and local variables could actually be declared C<const> to the C |
| 1567 | compiler. Steve Peters provided new C<*_set> macros and reworked the core to |
| 1568 | use these rather than assigning to macros in LVALUE context. |
| 1569 | |
| 1570 | Dave Mitchell improved the lexer debugging output under C<-DT> |
| 1571 | |
| 1572 | Nicholas Clark changed the string buffer allocation so that it is now rounded |
| 1573 | up to the next multiple of 4 (or 8 on platforms with 64 bit pointers). This |
| 1574 | should reduce the number of calls to C<realloc> without actually using any |
| 1575 | extra memory. |
| 1576 | |
| 1577 | The C<HV>'s array of C<HE*>s is now allocated at the correct (minimal) size, |
| 1578 | thanks to another change by Nicholas Clark. Compile with |
| 1579 | C<-DPERL_USE_LARGE_HV_ALLOC> to use the old, sloppier, default. |
| 1580 | |
| 1581 | For XS or embedding debugging purposes, if perl is compiled with |
| 1582 | C<-DDEBUG_LEAKING_SCALARS_FORK_DUMP> in addition to |
| 1583 | C<-DDEBUG_LEAKING_SCALARS> then a child process is C<fork>ed just before |
| 1584 | global destruction, which is used to display the values of any scalars |
| 1585 | found to have leaked at the end of global destruction. Without this, the |
| 1586 | scalars have already been freed sufficiently at the point of detection that |
| 1587 | it is impossible to produce any meaningful dump of their contents. This |
| 1588 | feature was implemented by the indefatigable Nicholas Clark, based on an idea |
| 1589 | by Mike Giroux. |
| 1590 | |
| 1591 | =head1 Platform Specific Problems |
| 1592 | |
| 1593 | The optimiser on HP-UX 11.23 (Itanium 2) is currently partly disabled (scaled |
| 1594 | down to +O1) when using HP C-ANSI-C; the cause of problems at higher |
| 1595 | optimisation levels is still unclear. |
| 1596 | |
| 1597 | There are a handful of remaining test failures on VMS, mostly due to |
| 1598 | test fixes and minor module tweaks with too many dependencies to |
| 1599 | integrate into this release from the development stream, where they have |
| 1600 | all been corrected. The following is a list of expected failures with |
| 1601 | the patch number of the fix where that is known: |
| 1602 | |
| 1603 | ext/Devel/PPPort/t/ppphtest.t #26913 |

| 1610 | =head1 Reporting Bugs |
| 1611 | |
| 1612 | If you find what you think is a bug, you might check the articles |
| 1613 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
| 1614 | bug database at http://bugs.perl.org. There may also be |
| 1615 | information at http://www.perl.org, the Perl Home Page. |
| 1616 | |
| 1617 | If you believe you have an unreported bug, please run the B<perlbug> |
| 1618 | program included with your release. Be sure to trim your bug down |
| 1619 | to a tiny but sufficient test case. Your bug report, along with the |
| 1620 | output of C<perl -V>, will be sent off to perlbug@perl.org to be |
| 1621 | analysed by the Perl porting team. You can browse and search |
