| | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change, the file template is always processed in original QString format. Trying to generate native paths before adding a missing placeholder mask could change the meaning of templates, such as "." and "..", which are now tested to mean "..XXXXXX" and "...XXXXXX", respectively. After ensuring the template includes a placeholder mask, the path is converted to a native *absolute* file path and the mask is sought for again. On Windows, native paths were already absolute. On Symbian, we'd need at least a clean path, as "." and ",," are not natively understood. There is a requirement that the placeholder mask /XXXXXX+/ makes it through this conversion unaltered, which relaxes prior requirements on *nix platforms. On Windows and Symbian the conversion is under Qt's control and not user-configurable.

* Use "native paths" on POSIX platforms as wellJoão Abecasis2011-10-211-27/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | And don't rely solely on "local8Bit" conversions. QFile defines an API for overriding how encoding conversions are done for filenames. In generating unique names, QTemporaryFile ignored that API and hardcoded the use of local 8-bit, implicitly assuming that that was appropriate. With this change, we switch that assumption to one where user supplied encoding function keeps the byte value of 'X' and '/', also assuming that encoded 'X' takes up a single-byte (i.e., the byte sequence for "XXXXXX" remains unchanged). There was also, and there still is an assumption in name generation that byte values for ASCII alpha-numeric characters are valid in the "native" encoding. In practice this change is compatible with UTF-8, Latin-1 and other ISO/IEC 8859 encodings. At any rate, it's very likely that only UTF-8 is relevant here.

* Atomic implementation of create file and obtain handle for Win/SymbianJoão Abecasis2011-10-211-49/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Besides generating a unique name, createFileFromTemplate now also acquires a file handle on all platforms. The file engine's native handle is passed by reference and modified in place. This fixes a long standing security issue on Windows. On Windows and Symbian platforms we directly use the "native" file path when processing the template and generating the unique name. Since the native encoding is known, conversions at this point are safe. Errors other than "file exists" are propagated to Q(Temporary)File, and result in a failure in open(). The changes also unify error handling and should give consistent behaviour across all platforms. Worthy of note, there's a change in behaviour on Windows and Symbian: fileNames returned by QTemporaryFile on Windows and Symbian are always absolute after open has been called. This has to do with how QFileSystemEntry::nativeFilePath works on these platforms. (Test was updated to reflect change in behaviour.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By making it possible to specify the place in memory where a type should be constructed, any meta-type can be allocated on the stack, for example. In the QML/JS QObject binding, this makes it possible to call slots and access properties from JavaScript without having to perform any mallocs (e.g. due to QVariant creation) in the C++ <--> JS value conversion, in the best case. In addition to QMetaType::construct() and QMetaType::destruct(), this change introduces QMetaType::typeSize(), which returns the size of a type in bytes. This can be used to prepare a suitable buffer for constructing a type using construct(). Benchmarks indicate that in-place construction is 2-5x faster than normal construction for core and GUI types on linux-g++. Note that there is already a QMetaType::construct() function in Qt 4, which has been renamed to QMetaType::create() in Qt 5. In order to avoid existing usages of construct() in user code to call the Qt 5 construct() (when they really meant to call create()), the third argument ("copy") of construct() is made mandatory. Hence, calls to QMetaType::construct() written for Qt 4 will cause a compile error when compiled with Qt 5, and the user must adapt his code.
