Update the perldelta for commits that I went through with git-deltatool from v5.13.9..356123f144 aside from these commits which I'm still not sure about: $ perl Porting/git-deltatool --mode summary --type blocking Scanning for blocking commits since v5.13.9... 692dce0 Fix symbol table associations in VMS::DCLsym fac4827 exporting a static function doesnt work 2f65c56 regexec.c: Handle sharp s in middle of backref 6e326e8 regcomp.c: Handle more cases of tricky fold chars b1e3e56 regexec.c: Give context for ANYOFV call 4e8910e regexec.c: Give context for ANYOFV call a5d74e1 regcomp.c: Remove special handling for U+00DF 8e3094e regcomp.c: tell regexec more about multi-char folds d18bf9d regcomp.c: Synthetic start class should include ord >255 folds 43322ea regcomp.c: Be more precise about ANYOF matching flag 4c9daa0 regcomp.c: Put two static functions in embed.fnc 17a3df4 Fix up \cX for 5.14 0cd14f2 Minor bugfixes to Socket::getaddrinfo d1de25c Add supplied tests from perl #83194. c95ca9b fix a s/non-utf8/is-utf8/ bit of nastiness 33fb6f3 Make Perl_sv_utf8_upgrade* respect nomg 4b8811a pp_subtr: preserve UTF8 flag in rare cases ff6e92e pp_subst: exit as soon as !match 6012dc8 allow wrap-around of PL_cop_seqmax d1bfb64 many string evals cause eventual scope issues b9d2ea5 Two Safefree() changes to make -DPERL_POISON builds work again. a12c501 In IPC::Open3's fd.t, correct the code added in 1f563db471aa8a00. ad01be2 Rearrange global.sym according to 'make regen' 67bd0bf Two more swash inversion list exports necessary for build on Win32. db2e1fb [perl #83406] Library compatibility and API documentation (v1.991). 9c9388a export the functions required by re 88c8c96 l1_char_class_tab.h: Remove multi-char fold targets 33d9abf code points above 0x7fff_ffff problematic 1bd9dc9 Add PL_foldable - a list of chars that participate in folds d764b54 Add initial inversion list object 2f833f5 regcomp.c: Generate different property for /i matching 6c29054 bmodpow() fails when GMP library is used. There's also things that should probably not be here, specifically the documentation section which I did earlien in the process and was probably way too inclusive. Additionally I've skipped every patch by Father Chrysostomos due to this note in private E-Mail: I plan to write perldelta entries for everything I committed that is worthy of note. I do not think I’ll have time to do the rest. I’m just letting you know, so our work does not overlap. Some of these entries also need better POD-ification. --- pod/perldelta.pod | 219 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 files changed, 219 insertions(+), 0 deletions(-) diff --git a/pod/perldelta.pod b/pod/perldelta.pod index 2a9bff9..8c57c38 100644 --- a/pod/perldelta.pod +++ b/pod/perldelta.pod @@ -86,6 +86,32 @@ C</i> must change to read the new boolean parameter passed it which is non-zero if case-insensitive matching is in effect; 0 if not.
