Nicholas Clark writes: As per my grant conditions, here is a report for the April period. I started the month looking at the Unicode Names code. At Karl's suggestion I changed it to parse the UnicodeData.txt file properly. Previously it had hardcoded various constants, particularly related to the CJK ideographs and Hangul syllables. The CJK ranges in Unicode have increased in the past, and so it's possible that they will ... read more |
Dave Mitchell writes: This month was mostly spent on removing global state from the regex engine, making re-entrantcy less error-prone. The extract from the merge commit description below gives you all the details you could ever want. Apart from that I spent a few hours re-enabling Copy-on_Write by default post the 5.18.0 release, plus a few other bits and pieces. It turns out that I have finally used up all ... read more |
Dave Mitchell writes: This month I worked on three 5.18 blocker tickets; all three being regressions related to my jumbo re_eval fix back in 5.17.1. The first, which I continued working on from last month, was the "Regexp::Grammars" bug. Basically, my reworking of the implementation assumed that a constant string segment like "foo" in /foo..../ would indeed be constant; but in the presence of bc. use overload::constant qr sub bless ... read more |

Nicholas Clark writes: In September I finally emerged from the rabbit hole of PL_main_start, that I entered into at some point in mid July. Father Chrysostomos has refactored OP allocation to always use a slab allocator, as part of fixing some very long standing bugs to do with OPs. At the start of parsing, a new slab is allocated. While parsing is ongoing, the slab is "owned" by the CV ... read more |
Dave Mitchell writes: As per my grant conditions, here is a report for the September period. This month I mostly spent my time: 1> Making regexes only copy the needed part of a string. In general when a regex is executed, and it is seen that captures exist or implicitly in the presence of or then perl makes a copy of the string that was matched against, so that subsequent ... read more |
The Perl Foundation is looking at giving some grants ranging from $500 to $2000 in November 2012. You don't have to have a large, complex, or lengthy project. You don't even have to be a Perl master or guru. If you have a good idea and the means and ability to accomplish it, we want to hear from you! Do you have something that could benefit the Perl community but ... read more |

Nicholas Clark writes: A fair chunk of the month was taken up with investigating three related areas: How code such as -e 'BEGIN {1}' is compiled, and the interaction between PL_main_cv, CvSTART PL_main_root and PL_main_start Code in op.c which calls CopLINE_set and warnings from multi-line constructions Building with -DPERL_DEBUG_READONLY_OPS to force shared ops to be read-only, and determining the causes of code trying to write to read-only ops Of these, ... read more |
Dave Mitchell writes: As per my grant conditions, here is a report for the July/August period. I spent a bit of time fixing a few issues causes by my rewriting of the implementation, then started to look into the last unclosed ticket still attached to the re_eval meta-ticket. This concerns code within that modifies the string being matched against, and generally causes assertion failures or coredumps: bc. my $text "a"; ... read more |
