* QTemporaryFile: fix the generation of names from templatesThiago Macieira2017-06-121-2/+5
| | | | | | | | | | | | | | | | First and most importantly, let's not use more than half of the template for the application's PID. With over 71% of all PIDs on a typical Linux system and 90% of those on a Darwin system having 5 decimal digits, using them all in a template that is usually 6 characters long is wasteful. That leaves only 1 character for the random part, thereby reducing the number of temporary files possible to only 52. So limit the PID to half the characters of the template. Second, let's use QRandomGenerator::bounded to create the the random part, instead of qrand (which is often unseeded at this point).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It only contained a concatenation of the individual rule sets, probably to fix their order in a central place, as well as simplifying iteration in defaultCategoryFilter(). Fix these two issues differently, but introducing a RuleSet enum that lists rule sets in the order in which they should be applied by defaultCategoryFilter(), and turn individual rule sets vectors into a C array of vectors. This enables two nested loops in defaultCategoryFilter to replace the one loop over 'rules'. Apart from building up 'rules' in updateRules(), this was the only access to that member. That leaves updateRules() with just the task of running defaultCategoryFilter() on the new rule sets. Consequently, a call to updateRules() can now replace the identical loop in installFilter(). Performance should not suffer. Iterating over a fixed-size array of vectors is hardly any slower than iterating over a single vector, and while the construction of 'rules' was probably a one-off task in most programs, this way of keeping the rules also saves memory because rules are not kept in two different vectors. It is also more maintainable, of course. Change-Id: Ibc132d096c8137dd02b034752646212e51208637 Reviewed-by: Kai Koehne <kai.koehne@qt.io> Reviewed-by: Olivier Goffart (Woboq GmbH) <ogoffart@woboq.com>

| * Split Q_COMPILER_UNICODE_STRINGS: add Q_STDLIB_UNICODE_STRINGSMarc Mutz2017-04-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit bf2160e72cd8840a8e604438cbdc807483ac980a, we can rely on charNN_t support in all compilers except MSVC 2013, and since that commit, we use (in 5.10, not 5.9, yet) !defined(Q_OS_WIN) || defined(Q_COMPILER_UNICODE_STRINGS) when we only need charNN_t, the type, as opposed to its library support (u16string, char_traits<char16_t>, ...). This patch splits the Q_C_UNICODE_STRINGS macro into two, adding Q_STDLIB_UNICODE_STRINGS for when we need std::uNNstring, leaving Q_C_UNICODE_STRINGS for when we need just charNN_t support. In QDebug, when constructing a QChar out of a char16_t, cast to ushort first, since QChar(char16_t) was only officially introduced in Qt 5.10. [ChangeLog][Potentially Source-Incompatible Changes] The internal Q_COMPILER_UNICODE_STRINGS macro is now defined if the compiler supports charNN_t, even if the standard library does not.

In setContent(QTextStream&), use the new readLineInto() function to re-use the capacity of a single QString for all lines. In setContent(QString), use splitRef() to split the lines. In either function, pass each line to parseNextLine(). In order to port all the parsing to QStringRef, I needed to make some semantic changes: the old code removed all whitespace right at the beginning. This is not possible with QStringRef. It also didn't feel right, since a line like [ r u l e s ] would successfully parse as the section named "rules". I added trimmed() calls at the beginning, and around the valueStr and pattern extraction, which should be good enough. Also, when a section is found, don't store it anymore. Instead, only store whether it was the [rules] section, because that's all we'll test for. That way, we don't have to convert QStringRefs to QString just to store them across parseNextLine() calls. Replace the setSection() function with setImplicitRulesSection(), because "rules" is all that was ever passed. This is private API, we can bring back some of the dropped flexibility later, as needed. [ChangeLog][Important Behavior Changes] Logging rules can no longer contain arbitrary whitespace such as within a category identifier.

To support more features of QProcess (without adding a plethora of overloads) we add a non-static method startDetached that can be used as follows: QProcess p; p.setProgram("cat"); p.setArguments("meow"); p.setWorkingDirectory("/tmp"); if (!p.startDetached()) qWarning("Cannot start process."); We plan to add support for nativeArguments, processEnvironment, standard{Output|Error}File and maybe more in subsequent commits. [ChangeLog][QtCore][QProcess] Added non-static QProcess::startDetached to support more features for detached processes.

* | | Port QResourceRoot::mappingRootSubdir() to QStringSplitterMarc Mutz2017-03-301-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code here performs a std::mismatch() on the normalized parts of 'root' and 'path', returning whether 'path' is a prefix of 'root'. If 'path' is a proper prefix of 'root', returns the first 'root' part after 'path', in '*match'. Instead of using QString::splitRef(), perform the splitting as we go, using this class' own tool, QStringSplitter. The goal here is to avoid the heap allocation caused by the QVector return of splitRef(), of course. But even though using QStringSplitter means the splitting is now purely inline, text size in optimized GCC 7 Linux AMD64 builds increases by only 24B.

For the purposes of this patch, it suffices to mention that the last two steps involved a QStringBuilder expression. Avoid having to build these strings by distinguishing between the lookups using an enum instead of a string prefix. Since qt_hash() calls can now be chained, form the hash value by hashing the prefix character and the domain (part) separately. Also perform the expensive fromUtf8() call only when the string prefix (if any) matched. Once we have nothrow UTF-8/UTF-16 comparison operators, qIsEffectiveTLD() will no longer allocate memory, and run at full speed. Not there, yet, though. I have full confidence that the optimizer will have field day with this, inline all three containsTLDEntry() calls, and constant-fold the checks inside the loop. GCC does, so I didn't try to do it by hand. Change-Id: I1a7647ff52b6742310928ad859d851d1f0c6bdc3 Reviewed-by: Lars Knoll <lars.knoll@qt.io>
