* Teach QByteArrayView how to parse numbersEdward Welbourne2021-08-301-1/+22
| | | | | | | | | | | | Now that we don't need '\0'-termination on the data, this is possible. Moved QByteArray's tests to tst_QByteArrayApiSymmetry and added some more test-cases. [ChangeLog][QtCore][QByteArrayView] Added numeric parsing methods.

* QLocale: improve documentation snippetIvan Solovev2021-08-261-9/+11
| | | | | | | | | | | | QString::toDouble() now always uses C locale, so the previous code snippet does not make much sense, as the results do not depend on the selected default locale. The updated snippet uses the default locale, which allows to show the difference between locales.

* QRegularExpressionMatch: add a way to know if a capturing group capturedGiuseppe D'Angelo2021-08-251-0/+12
| | | | | | | | | | | | | | | | | | | | | | | Relying on the fact that a given capturing group captured a null string doesn't allow users to distinguish whether a capturing group did not capture anything, or captured a null substring (say, from a null subject string). Perl allows for the distinction: the entries in the @- and @+ arrays are set to values in case there is a capture, but they're undef otherwise. PCRE2 gives us the information already in the results "ovector", but it was simply not exposed to QREM users. So, expose it. [ChangeLog][QtCore][QRegularExpressionMatch] Added the hasCaptured() family of functions to know if a given capturing group has captured something.

* QObject: optimize the common case of findChildren(QString())Marc Mutz2021-07-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Outside tests, all in-tree callers of QObject::findChildren() pass no name to match, and in my experience that is also true for the vast majority of out-of-tree users. Avoid the temporary QString creation in the caller and the repeated QString::isNull() checks in the implementation by overloading findChildren() without a name argument and checking for name.isNull() only once, forking off into separate helper functions. Adjust in-tree callers that used an explicit `QString()` argument in order to pass options, which goes to show that `name` should never have been the first argument of findChilden() in the first place, even though I appreciate the symmetry with findChild() (the use-cases of which, however, are radically different). Change a `findChildren().size() == 0` call found while scanning for findChildren() calls to `!findChild()` as a drive-by. Modernize loops in the various qt_qFindChild{,ren}_helper() overloads to match how the new code looks. [ChangeLog][QtCore][QObject] Added findChildren() overload taking no name (thus optimizing this common case).

* QProcess/Unix: introduce setChildProcessModifier()Thiago Macieira2020-09-081-20/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ChangeLog][Source-Incompatible Changes] QProcess::setupChildProcess() was removed. To execute code in a child process, use QProcess::setChildProcessModifier() [ChangeLog][QtCore][QProcess] Added setChildProcessModifier() function with which one can provide code to be run in the Unix child process between fork() and execve(). With this function, it is no longer necessary to derive from QProcess in order to execute actions in the child process. Another reason is that we can tell whether the std::function carries a valid target much more easily than we can tell whether QProcess was overridden. The setupChildProcess() virtual function does not need to be marked final, since no overrider could ever return an inaccessible private class. This also makes sure the error presented to the user is about the return type, not about attempting to override a final. Clang: error: virtual function 'f' has a different return type ('void') than the function it overrides (which has return type 'QProcess::Use_setChildProcessModifier_Instead') GCC: error: conflicting return type specified for 'virtual void MyProcess::setupChildProcess()' note: overridden function is 'virtual QProcess::Use_setChildProcessModifier_Instead QProcess::setupChildProcess()' ICC: error: return type is neither identical to nor covariant with return type "QProcess::Use_setChildProcessModifier_Instead" of overridden virtual function "QProcess::setupChildProcess" MSVC is not relevant since it doesn't compile to Unix.

* Clean up the QByteArray API and implementationLars Knoll2020-09-031-1/+1
| | | | | | | | | | | | | | Add overloads using a QByteArrayView where it makes sense, and call those inline from the other overloads. Remove overloads that are not required anymore (due to implicit conversion of a const char * to a QByteArrayView). Guard all implementations against passing this object to them.
