* Implement:Nick Ing-Simmons2001-03-241-1/+3
| | | | | | 1. open($fh,"+<",undef); # add test to t/io/open.t 2. open($fh,"+<",\$var); # New test t/lib/io_scalar.t p4raw-id: //depot/perlio@9318
* Perlio internals re-organized.Nick Ing-Simmons2001-03-231-5/+12
| | | | | | | | | | | | - open process creates AV of layer/arg pairs (appends layers from open() or open.pm to default list). - push arg is now an SV. - layer ->Open get passed the AV - open is no longer mandatory method. - topmost layer that has ->Open method does the open - any layers above are pushed once that returns. - vtable re-ordered so dummy layers need only provide push/pop methods. p4raw-id: //depot/perlio@9314
* Snapshot of new PerlIO open scheme. Still buggy - mainly in ↵Nick Ing-Simmons2001-03-221-6/+2
| | | | | | | | | | | | | | | open($fh,">&STDOUT!") type code. - Invent PerlIO_openn() - which has "lots" of args a bit like do_openn() which is its main caller. In particular now has access to "extra" args, and can tell when an open handle is "reopened" (or duped?). - In -Duseperlio PerlIO_open() et. al. are now wrappers on PerlIO_openn(). - In -Uuseperlio (untested as yet) PerlIO_openn() is a wrapper on PerlIO_open() et. al. (i.e. other way round). - Collapse "vtable" entries for layers - was fdopen/open/reopen now just open with args close to PerlIO_openn(). p4raw-id: //depot/perlio@9302
* Clean up a few core dumps when layers are used in unexpected ways.Nick Ing-Simmons2001-02-181-9/+10
| | | | | (Still not "right"...) p4raw-id: //depot/perlio@8820
* Make "real" layers of ":utf8" and ":raw".Nick Ing-Simmons2001-01-211-0/+3
| | | | | | | So now PERLIO=utf8 perl ... does what Andreas wanted. Fix arg passing in open.pm (still have a Carp issue). p4raw-id: //depot/perlio@8511
* Integrate mainline.Nick Ing-Simmons2000-12-191-1/+2
| | | p4raw-id: //depot/perlio@8202
* Finish 1st pass of "encoding" layer e.g. :Nick Ing-Simmons2000-12-111-0/+1
| | | | | open($fh,"<encoding(iso8859-7)",$greek) || die; p4raw-id: //depot/perlio@8085
* Not merge worthy...Nick Ing-Simmons2000-12-101-2/+2
| | | | | | | | Allow arg to layers e.g. open($fh,"<:encode(iso8859-15)",$name) syntax is modelled on attributes. Untested fix for io/utf8 on Win32 etc. Very clumsy start to the encode layer. p4raw-id: //depot/perlio@8076
* PERL_IMPLICIT_SYS (almost) works - something odd with "signal"Nick Ing-Simmons2000-12-041-1/+1
| | | p4raw-id: //depot/perlio@7983
* Fix 'mmap' lib/filehand.t (ungetc) test fail.Nick Ing-Simmons2000-12-011-16/+18
| | | | | | | | | | | Make 'unix' pass most tests - do unread by temporary push of layer ("pending") holding unread chars - fast_gets is now based on per-handle flag - relax one of io/pipe.t tests to allow print to fail and close to succeed so that it passes on unbuffered "unix" layer. Remaining fail is sporadic and a genuine race condition between parent/child in fork test. p4raw-id: //depot/perlio@7942
* Re-arrange crlf vs binary for platforms that care.Nick Ing-Simmons2000-11-241-4/+18
| | | | | | | | crlf layer is now "the" buffer layer and can turn its behaviour on/off. Lip-service to making stdio layer work on such platforms (untested). Now fails 3 tests rather than one, checkin to see if I can debug the issue under linux. (Do not merge.) p4raw-id: //depot/perlio@7853
* Add dummy crlf layer (just as buffer)Nick Ing-Simmons2000-11-191-0/+1
| | | | | Correct 1st bug - one layer of indirection. p4raw-id: //depot/perlio@7755
* PerlIO #include and #ifdef re-work.Nick Ing-Simmons2000-11-141-0/+131
