| | | * Fix non-Latin1 strings in QJsonDocument on big-endian platformsThiago Macieira2016-01-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QJsonDocument stores the entire JSON tree in its binary format. Since the binary format is the same on-disk as in-memory, it has a fixed endianness. But when converting from QString to the little-endian format, the code accidentally converted twice (from little endian, to little endian), which resulted in a no-op and the string got stored as big-endian. It's like encrypting with double-ROT13. No new testcase because tst_QtJson::removeNonLatinKey was already failing and gets fixed by this commit.

Defining those macros in forkfd.c is not enough: forkfd_qt.cpp also sets _POSIX_C_SOURCE, and sys/cdefs.h can be included implicitly via Qt's headers (<algorithm> ends up pulling unistd.h that leads to sys/cdefs.h and sys/types.h with both libstdc++ and older libc++ versions).

When a ZWNBSP occurs in the middle of a utf8 character sequence, and the SIMD conversion does some work (meaning: the length is at least 16 characters long), it would not recognize the fact some charactes were already decoded. So the conversion would then strip the ZWNBSP out, thinking it's a BOM. The non-SIMD conversion did not have this problem: the very first character conversion would already set the headerdone flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When QDateTime::addDate() and friends sanitize their end-state, they were using the DST status of their start-state (if known) to control it. This lead to misguided results and, in particular, inconsistent results given that a raw-constructed QDateTime comes into being ignorant of its DST, while a .toLocalTime() one knows its DST. Furthermore, the code to do this was triplicated, tricky and poorly explained. So pull it out into a local static function and explain what it's doing, and why, more clearly and only once.

It broke too many users, even though all of them deserved to be broken. The new functionality will be provided by differently-named functions, where possible (problem: equality operators). I did not revert the fix for the off-by-one error in tst_qtextdocumentfragment.cpp. I also didn't revert the change in the inequality relational operators, since for all strings s1, s2 and s2' where s2' is s2 truncated at the first NUL, s1 < s2 ⟺ s1 < s2' (since NUL < c for any c != 0), and, trivially, for ≤, >, ≥, too. This does not hold for = and ≠, of course, since "foo\0bar" ≠ "foo".

When telling the compiler to target an other/older version, the crc32 code is not compiled.

Hence we do the inline replacement manually. QThreadStorage and QThread tests continue to work, so it seems to be an oversight by Microsoft.
