* Bootstrap: remove QTemporaryFileThiago Macieira2024-03-131-1/+1
| | | | | | | | | Done by harmonizing the use on the QT_CONFIG(temporaryfile) macro and fixing one test that was missing. We can't remove the older macro because it is marked PBULIC) but we don't need to use it ourselves.

This test was here only to produce an error at CMake time instead of at build time, but that test costs 650 ms for everyone running CMake without cached results.

* Long live QPermissions!Tor Arne Vestbø2022-11-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many features of today's devices and operating systems can have significant privacy, security, and performance implications if misused. It's therefore increasingly common for platforms to require explicit consent from the user before accessing these features. The Qt permission APIs allow the application to check or request permission for such features in a cross platform manner. The check is always synchronous, and can be used in both library and application code, from any thread. The request is asynchronous, and should be initiated from application code on the main thread. The result of the request can be delivered to lambdas, standalone functions, or regular member functions such as slots, with an optional context parameter to manage the lifetime of the request. Individual permissions are distinct types, not enum values, and can be added and extended at a later point.

* Bootstrap: explicitly include stdlib.h to check for __GLIBC_PREREQIvan Solovev2022-10-061-0/+2
| | | | | | | | | | | | | | | | Previously the code was relying on the includes in qglobal.h, but now when we try to get rid of qglobal.h we can end up in a situation when qconfig-bootstrap.h was first included before qglobal.h (__GLIBC_PREREQ not defined), and also included once again after qglobal.h (__GLIBC_PREREQ defined, at least on linux). This resulted in redefenition of Qt features dependent on __GLIBC_PREREQ. This patch fixes it by explicitly including the stdlib.h header which will provide __GLIBC_PREREQ definition when it is available.

Make solaris fail the reduce relocation test. getauxval is specific to GNU libc and some other libc implementations on Linux but sys/auxv.h is not. The bootstrap uses sys/aux.h as the only indication for getauxval. This breaks builds on Solaris, so only make sys/auxv.h an indicator for getauxval on linux or glibc based systems. Solaris uses X11 so add it to the X11_SUPPORTED list. Solaris network libraries for sockets etc are in socket and nsl. ifreq does not have a member ifr_ifindex on Solaris, it uses ifr_index. Add test to check if ifr_index is a member of ifreq. The first struct in the in_addr union on solaris is defined as four uint8_t, therefore four arguments are needed for its initializer list.

| * Split cborstream feature in twoUlf Hermann2019-12-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reading of Cbor streams is substantially more complicated than writing as it requires float16 support. When writing Cbor, we can just choose to always write 32bit floats, even if we could compress the numbers into 16 bits. We need Cbor writing in the bootstrap library, but we cannot easily add float16 support. Furthermore, Cbor reading is required for plugin support, but not Cbor writing. It might make sense for some users to build a custom Qt with Cbor writing disabled. Therefore, provide two features, cborstreamreader and cborstreamwriter, split up the code in cborstream.{h|cpp} into several files, and enable Cbor writing in the bootstrap library.

Compression levels range from 1 (fastest, least compression) to 19 (slowest, best compression). Level 0 tells the library to choose an implementation-defined default. \ The default compression level is "heuristic" (level -1): under this mode, RCC will attempt a very fast compression (level 1) and check if the file was sufficiently compressed. If it was, then RCC will compress again using an implementation-defined level.

It also produces better results at less CPU time than the best compression zlib has to offer. More importantly, the decompression time reduces in all cases (the numbers listed are for max compression, with slightly better results for the defaults).

* QResource: add support for resources compressed with ZstandardThiago Macieira2018-12-111-0/+1
| | | | | | | | | | | | | | | | | See next commit for details on why this is a good idea. [ChangeLog][Important Behavior Changes] The Qt resource system now supports compressing content using the Zstandard (https://zstd.net) algorithm. Compared to zlib, it compresses better for the same CPU time, so this algorithm is the default. QResource::isCompressed() returns true for either compression algorithm. Use QResource::compressionAlgorithm() to find out which algorithm to decompress. QFile will automatically decompress using the correct algorithm.
