520 | or leak resources, or changes in resources. | |

6076 | /* And below is a version of the above table that accepts only strict UTF-8. |
6077 | * Hence no surrogates nor non-characters, nor non-Unicode. Thus, if the input | |
6078 | * passes this dfa, it will be for a well-formed, non-problematic code point | |
6079 | * that can be returned immediately. | |
6080 | * | |
6081 | * The "Implementation details" portion of | |
f6521f7c | 6082 | * https://bjoern.hoehrmann.de/utf-8/decoder/dfa/ shows how |
123deead KW |
6083 | * the first portion of the table maps each possible byte into a character |
6084 | * class. And that the classes for those bytes which are start bytes have been | |
6085 | * carefully chosen so they serve as well to be used as a shift value to mask | |
6086 | * off the leading 1 bits of the start byte. Unfortunately the addition of | |
6087 | * being able to distinguish non-characters makes this not fully work. This is | |
6088 | * because, now, the start bytes E1-EF have to be broken into 3 classes instead | |
6089 | * of 2: | |
6090 | * 1) ED because it could be a surrogate | |
6091 | * 2) EF because it could be a non-character | |
6092 | * 3) the rest, which can never evaluate to a problematic code point. | |
6093 | * | |
6094 | * Each of E1-EF has three leading 1 bits, then a 0. That means we could use a | |
6095 | * shift (and hence class number) of either 3 or 4 to get a mask that works. | |
6096 | * But that only allows two categories, and we need three. khw made the | |
6097 | * decision to therefore treat the ED start byte as an error, so that the dfa | |
6098 | * drops out immediately for that. In the dfa, classes 3 and 4 are used to | |
6099 | * distinguish EF vs the rest. Then special code is used to deal with ED, | |
6100 | * that's executed only when the dfa drops out. The code points started by ED | |
a3815e44 | 6101 | * are half surrogates, and half hangul syllables. This means that 2048 of |
123deead KW |
6102 | * the hangul syllables (about 18%) take longer than all other non-problematic |
6103 | * code points to handle. | |
6104 | * | |
6105 | * The changes to handle non-characters requires the addition of states and | |
6106 | * classes to the dfa. (See the section on "Mapping bytes to character | |
6107 | * classes" in the linked-to document for further explanation of the original | |
6108 | * dfa.) | |

6615 | * locale-dependent functions in the core isn't thread-safe. The latter | |
6616 | * case is generally because they return a pointer to a static buffer, which | |
6617 | * may be per-process instead of per-thread. There are supposedly | |
6618 | * re-entrant, safe versions for all of them Perl currently uses (which the | |
6619 | * #if above checks for), but most platforms don't have all the needed ones | |
6620 | * available, and the Posix standard doesn't require nl_langinfo_l() to be | |
6621 | * fully thread-safe, so a Configure probe was written. localeconv_l() is | |
6622 | * uncommon, and judging by bug reports on the web, some earlier library | |
6623 | * localeconv_l versions were broken, so perhaps a probe is in order for | |

6631 | * the problem of another thread changing the locale, and the buffer being | |
6632 | * overwritten (the code copies the results to a safe place before releasing | |
6633 | * the mutex). Ideally, for locale thread-safe platforms where the only | |
6634 | * issue is another thread clobbering the function's static buffer, there | |
6635 | * would be a separate mutex for each such buffer. Otherwise, things get | |

df127a67 | 7737 | * |
60d50332 | 7738 | * The fraction_1 is the most significant (numbering as by DEC/Digital), |
6ce22998 JH |
7739 | * while the rightmost bit in each fraction is the least significant: |
7740 | * in other words, big-endian bit order within the fractions. | |
df127a67 | 7741 | * |
6ce22998 | 7742 | * The fraction segments themselves would be big-endianly, except that |
df127a67 | 7743 | * within 32 bit segments the less significant half comes first, the more |
6ce22998 | 7744 | * significant after, except that in the format H (used for long doubles) |
df127a67 | 7745 | * the first fraction segment is alone, because the exponent is wider. |
6ce22998 JH |
7746 | * This means for example that both the most and the least significant |
7747 | * bits can be in the middle of the floats, not at either end. | |

8093 | * This means that in this format there are 61 bits available | |
8094 | * for the nan payload. | |
8095 | * | |
3bbe6a60 JH |
8096 | * Note that the 32-bit x86 ABI cannot do signaling nans: the x87 |
8097 | * simply cannot preserve the bit. You can either use the 80-bit | |
8098 | * extended precision (long double, -Duselongdouble), or use x86-64. | |
8099 | * | |
453b60f1 JH |
8100 | * In all platforms, the payload bytes (and bits, some of them are |
8101 | * often in a partial byte) themselves can be either all zero (x86), | |
8102 | * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double | |
8103 | * or in a double-double, the first half of the payload can follow the | |
8104 | * native double, while in the second half the payload can be all | |
8105 | * zeros. (Therefore the mask for payload bits is not necessarily | |
8106 | * identical to bit complement of the NaN.) Another way of putting | |
8107 | * this: the payload for the default NaN might not be zero. | |
8108 | * | |
8109 | * For the x86 80-bit long doubles, the trailing bytes (the 80 bits | |
8110 | * being 'packaged' in either 12 or 16 bytes) can be whatever random | |
8111 | * garbage. | |
8112 | * | |
8113 | * Furthermore, the semantics of the sign bit on NaNs are platform-specific. | |
8114 | * On normal floats, the sign bit being on means negative. But this may, | |
8115 | * or may not, be reverted on NaNs: in other words, the default NaN might | |
8116 | * have the sign bit on, and therefore look like negative if you look | |
8117 | * at it at the bit level. | |
8118 | * | |
8119 | * NaN payloads are not propagated even on copies, or in arithmetics. | |
8120 | * They *might* be, according to some rules, on your particular | |
8121 | * cpu/os/compiler/libraries, but no guarantees. | |
8122 | * | |
8123 | * To summarize, on most platforms, and for 64-bit doubles | |
8124 | * (using big-endian ordering here): | |
8125 | * | |
8126 | * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet | |
8127 | * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet | |
8128 | * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling | |
8129 | * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling | |
8130 | * | |
8131 | * The C99 nan() is supposed to generate *quiet* NaNs. | |
8132 | * | |
8133 | * Note the asymmetry: | |
8134 | * The 7FF0000000000000 is positive infinity, | |
8135 | * the FFF0000000000000 is negative infinity. | |
