* EBCDIC sanity - phase INick Ing-Simmons2001-03-101-95/+95
| | | | | | | | | | | | | | - rename utf8/uv functions to indicate what sort of uv they provide (uvuni/uvchr) - use utf8n_xxxx (c.f. pvn) for forms which take length. - back out vN.N and $^V exceptions to e2a/a2e - make "locale" isxxx macros be uvchr (may be redundant?) Not clear yet that toUPPER_uni et. al. return being handled correctly. The tr// and rexexp stuff still needs an audit, assumption is they are working in Unicode space. Need to provide v5.6 names for XS modules (decide is uni or chr ?). p4raw-id: //depot/perlio@9096

* Misapplied regex optimizations when \C is present.Jarkko Hietaniemi2001-02-181-18/+9
| | | | | | | | | | Fixes 20001230.002. What still remains broken is that the submatches that have \C in them get their UTF8 flag on because their parent SV has it on. This will result in malformed UTF8 if a \C happened to match a non-ASCII byte. p4raw-id: //depot/perl@8836

* The code in regcppop() (see #7878) contains the correct lowerJarkko Hietaniemi2000-11-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | limit for the unused submatch 'cleanup' loop so that under "use utf8" the following code wouldn't dump core: "," =~ /([^,]*,)*/ With the the wrong lower limit (>=1) the cleanup loop in regtry() stomped beyond allocated area in the startp[] array. Therefore, copied the correct lower loop limit (*PL_reglastparen) to regtry(). Note: something may still not be quite right: why was the _higher_ loop limit (prog->nparens) different in the utf8 case? After this patch "./perl -Ilib -Mutf8 t/op/regexp.t" works without core dumps, there were about 17 of them before the patch (with us since Perl 5.7.0). Two failures, still: 496 and 505 (though these may not be severe). Patch #7881 is also needed since both the cleanup loops seem to be needed. Also, the t/op/pat#44 seems to core dump under utf8. Plus a couple of failures. UGH-8. p4raw-id: //depot/perl@7879
* The unused submatch cleanup code in regtry() seems to be more crucial,Jarkko Hietaniemi2000-11-271-1/+17
| | | | | | | the code in regcppop() seems to be redundant for the test suite -- but it contains a germ of truth, and it needed for the build process itself: see #7879 and #7881. p4raw-id: //depot/perl@7878

* Continue the internal UTF-8 API tweaking.Jarkko Hietaniemi2000-10-251-4/+4
| | | | | | | | Rename utf8_to_uv_chk() back to utf8_to_uv() because it's used much more than the simpler API, now called utf8_to_uv_simple(). Still not quite happy with API, too much partial duplication of functionality. p4raw-id: //depot/perl@7439
* Make the UTF-8 decoding stricter and more verbose whenJarkko Hietaniemi2000-10-241-4/+9
| | | | | | | | | | | | malformation happens. This involved adding an argument to utf8_to_uv_chk(), which involved changing its prototype, and prefer STRLEN over I32 for the UTF-8 length, which as a domino effect necessitated changing the prototypes of scan_bin(), scan_oct(), scan_hex(), and reg_uni(). The stricter UTF-8 decoding checking uses Markus Kuhn's UTF-8 Decode Stress Tester from http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-test.txt p4raw-id: //depot/perl@7416
