* Add a configure-time check for QT_COMPILER_SUPPORTS_SIMD_ALWAYSThiago Macieira2017-11-301-5/+1
| | | | | | | | | | | | | | | | This has two main benefits: 1) introduces a qmake CONFIG we can use in .pro/.pri/.prf files 2) removes the need to keep an up-to-date list of which compilers support the feature The test is implemented as trying to compile every single SIMD test we currently have, but without passing the -mXXX option. The reason for trying all of them is that some people may have modified their mkspecs to add -mXXX options or -march=XXX, which could enable the particular feature we tried, resulting in a false positive outcome.

* QStorageInfo: use Linux's /proc/self/mountinfo to get the subvolumeThiago Macieira2017-11-301-28/+207
| | | | | | | | | | | | | | | | This allows us to get "subvolumes" on all filesystem types. We do that by detecting the subdirectory that was bind-mounted. /proc/self/mountinfo has been in the kernel since 2.6.26. Since btrfs was only added on 2.6.29, there is no loss of functionality for btrfs users. I've tested this with subvolume or mountpoint names containing spaces, tabs and newlines.

Moreover, since std::mt19937 doesn't make it easy to provide the ideal size either, we can't actually write code that operates optimally given a quint32 range either -- we only provide it via std::seed_seq, which is inefficient. However, we can do it internally by passing QRandomGenerator to the std::mersenne_twister_engine constructor, as it's designed to work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace with calculateTransitionForYear(), which just does one of the transitions, and wrap that with a pair-struct type to call it for DST and standard time, respectively. This also eliminate in/out arguments, which is said to be good for optimisers. Change-Id: I1e397404a0abceee7654524902af5be4eb88a625 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* | | Add QFontMetrics(F)::horizontalAdvance() functionEskil Abrahamsen Blomfeldt2017-11-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A source of constant confusion is the QFontMetrics::width() function, which does not return the bounding width of the text, but the advance width. We deprecate this and add horizontalAdvance() instead, to avoid the confusion in the future. Note that there was an internal width() overload which was only there for the purpose of supporting the Qt::TextBypassShaping flag. This flag has already been replaced by public API, so no such overload is added. Instead, we deprecate the TextBypassShaping flag as well, which makes sense, since a replacement has been made. Also note that there was a consistency problem with QFontMetrics and QFontMetricsF, which are supposed to be interchangeable. The QFontMetrics::width() functions for strings took an optional int length argument, while the floating point version did not. This error is corrected in the advance() functions. [ChangeLog][QtGui][Text] Added QFontMetrics::horizontalAdvance() and QFontMetricsF::horizontalAdvance() to replace the confusingly named width() function. The latter has now been deprecated.

* | | QDirIterator: Skip inconvertible file names on UnixAlexander Volkov2017-11-141-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case when user's local encoding is UTF-8, QDirIterator may list entries which names can't be correctly converted from UTF-8 to UTF-16, e.g. for "\xC0\xB0" file name QDirIterator::fileName() returns "\uFFFD\uFFFD" (FFFD is a code of Replacement Character). The problem is that you can't do anything with such directory entries because there is no way to get the original entry names. List only those names that can be converted to QString and then back to the local encoding without corruption.

For non-local filesystems, the backend needs support and that might need server-side support too. So we may get EINVAL errors for those, in which case we fall back to link/unlink, which in turn can fall back to rename(). EINVAL can also happen if we attempt to make a directory a subdirectory of itself. In that case, we will attempt to link() it, which will result in EPERM as we can't hardlink directories. Then we try rename() again, which should result in the expected EINVAL.
