- API-space: complete the list of things that constitute public api - -Configure - make configuring+building away from source directory work (VPATH et al) - this is related to: cross-compilation configuring (see Todo) - _r support (see Todo for mode detailed description) - POSIX 1003.1 1996 Edition support--realtime stuff: - POSIX semaphores, message queues, shared memory, realtime clocks, - timers, signals (the metaconfig units mostly already exist for these) - PREFERABLY AS AN EXTENSION - UNIX98 support: reader-writer locks, realtime/asynchronous IO - PREFERABLY AS AN EXTENSION - IPv6 support: see RFC2292, RFC2553 - PREFERABLY AS AN EXTENSION - there already is Socket6 in CPAN - -Long doubles - figure out where the PV->NV->PV conversion gets it wrong at least - in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the - regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t, - (?:9|8999\d+) and the like. - -64-bit support - Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might - be in some systems the only thing working as quadtype and uquadtype. - more pain: long_long, u_long_long. - -Locales - deprecate traditional/legacy locales? - How do locales work across packages? - figure out how to support Unicode locales - suggestion: integrate the IBM Classes for Unicode (ICU) - http://oss.software.ibm.com/developerworks/opensource/icu/project/ - ICU is "portable, open-source Unicode library with: - charset-independent locales (with multiple locales - simultaneously supported in same thread; character - conversions; formatting/parsing for numbers, currencies, - date/time and messages; message catalogs (resources); - transliteration, collation, normalization, and text - boundaries (grapheme, word, line-break))". - Check out also the Locale Converter: - http://alphaworks.ibm.com/tech/localeconverter - There is also the iconv interface, either from XPG4 or GNU (glibc). - iconv is about character set conversions. - Either ICU or iconv would be valuable to get integrated - into Perl, Configure already probes for libiconv and <iconv.h>. - -Regexen - make RE engine thread-safe - a way to do full character set arithmetics: now one can do - addition, negate a whole class, and negate certain subclasses - (e.g. \D, [:^digit:]), but a more generic way to add/subtract/ - intersect characters/classes, like described in the Unicode technical - report on Regular Expression Guidelines, - http://www.unicode.org/unicode/reports/tr18/ - (amusingly, the TR notes that difference and intersection - can be done using "Perl-style look-ahead") - difference syntax? maybe [[:alpha:][^abc]] meaning - "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]? - (maybe bad, as we explicitly disallow such 'ranges') - intersection syntax? maybe [[..]&[...]]? - POSIX [=bar=] and [.zap.] would nice too but there's no API for them - =bar= could be done with Unicode, though, see the Unicode TR #15 about - normalization forms: - http://www.unicode.org/unicode/reports/tr15/ - this is also a part of the Unicode 3.0: - http://www.unicode.org/unicode/uni2book/u2.html - executive summary: there are several different levels of 'equivalence' - trie optimization: factor out common suffixes (and prefixes?) - from |-alternating groups (both for exact strings and character - classes, use lookaheads?) - approximate matching - -Security - use fchown, fchmod (and futimes?) internally when possible - use fchdir(how portable?) - create secure reliable portable temporary file modules - audit the standard utilities for security problems and fix them - -Reliable Signals - custom opcodes - alternate runops() for signal despatch - figure out how to die() in delayed sighandler - make Thread::Signal work under useithreads - -Win32 stuff - sort out the spawnvp() mess for system('a','b','c') compatibility - work out DLL versioning - -Miscellaneous - introduce @( and @) because group names can have spaces - add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?) - sub-second sleep()? alarm()? time()? (integrate Time::HiRes? - Configure doesn't yet probe for usleep/nanosleep/ualarm but - the units exist) - floating point handling: nans, infinities, fp exception masks, etc. - At least the following interfaces exist: fp_classify(), fp_class(), - class(), isinf(), isfinite(), finite(), isnormal(), unordered(), - <ieeefp.h>, <fp_class.h> (there are metaconfig units for all these), - fp_setmask(), fp_getmask(), fp_setround(), fp_getround() - (no metaconfig units yet for these). - Don't forget finitel(), fp_classl(), fp_class_l(), (yes, both do, - unfortunately, exist), and unorderedl(). - PREFERABLY AS AN EXTENSION. - As of 5.6.1 there is cpp macro Perl_isnan(). - fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if - both arguments are IVs/UVs: it sucks that one cannot see - the 'carry flag' (or equivalent) of the CPU from C, - C is too high-level... - replace pod2html with new PodtoHtml? (requires other modules from CPAN) - automate testing with large parts of CPAN - turn Cwd into an XS module? (Configure already probes for getcwd()) - mmap for speeding up input? (Configure already probes for the mmap family) - sendmsg, recvmsg? (Configure doesn't probe for these but the units exist) - setitimer, getitimer? (the metaconfig units exist) - -Ongoing - keep filenames 8.3 friendly, where feasible - upgrade to newer versions of all independently maintained modules - comprehensive perldelta.pod - -Documentation - describe new age patterns - update perl{guts,call,embed,xs} with additions, changes to API - convert more examples to use autovivified filehandles - document Win32 choices - spot-check all new modules for completeness - better docs for pack()/unpack() - reorg tutorials vs. reference sections - make roffitall to be dynamical about its pods and libs - |
