* RCCFileInfo: refactorAhmad Samir2023-01-071-1/+1
| | | | | | | | | | | | | | | - Initialize members in-class, and in ctor init-list as needed. This simplifies the constructor and is generally safer as one can't forget to initialize a member, especially built-in types - Add copy control members, this is actually a move only class because of the QMultiHash<QString, RCCFileInfo*> member and the destructor calling qDeleteAll - Minor, save a couple of bytes by reordering the members so that they are in 8 byte chunks as much as possible, sizeof(*this) is now 104, was 120 Change-Id: Idcf7c5a99fdf02854e09e3c1cade6c8d238ed492 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* CMake: Allow contents of resources to be replaced by empty filesUlf Hermann2022-12-171-0/+1
| | | | | | | | | | | | | | | This makes it possible to process QML files using qmlcachegen, and retain the file nodes in the resource file system, but remove their actual content from the binary. To do so, you need to mark your files with the QT_DISCARD_FILE_CONTENTS source file property.

* Resources: reject compressed content we can't decompressThiago Macieira2018-12-121-0/+2
| | | | | | | | | | | | | | | | | | | This solution is composed of two features: 1) C++ code generated by RCC uses two symbols exported from QtCore that are only present if the feature was compiled in. If the feature was not compiled in, this will cause a linker error either at build time or at load time (if they were functions, the error could be at runtime). 2) Binary files generated by RCC have a new header field containing flags. We're currently using two flags, one for Zlib and one for Zstandard. This means we now have binary RCC format version 3.

* RCC: Add support for Zstandard compressionThiago Macieira2018-12-111-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ChangeLog][RCC] RCC 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. To go back to the previous algorithm, pass command-line option --compress-algo=zlib. 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. The following are the 4 biggest files we store as resources in qtbase: Orig Size Name 2197605 src/corelib/mimetypes/mime/packages/freedesktop.org.xml 2462423 tests/auto/corelib/tools/qchar/data/NormalizationTest.txt 6878748 tests/auto/other/qcomplextext/data/BidiCharacterTest.txt 7959972 tests/auto/other/qcomplextext/data/BidiTest.txt The current RCC (zlib, level -1 "default" and level 9), produces for those files: L(-1) Compr.

* Make RCC handle bigger binarieshjk2014-06-061-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally, RCC in "C mode" was meant to bundle small resources into a binary, like help texts or an occasional icon. RCC produces a .cpp file containing the actual data in a char array which is then passed to the compiler and linker as a normal source file. Larger resources should be compiled in RCC's binary mode and loaded at run time. Current Qt Quick use tries to deploy large hunks of data in "C mode", causing heavy compiler/system load. This patch works around the issue by splitting the process into three parts: 1. Create a C++ skeleton, as usual, but use a placeholder array with "easily compilable" (mostly NULs) data instead. 2. Compile the skeleton file. 3. Replace the placeholder data with the real binary data. time (qmake5 ; make clean ; make) takes 1.3 s real time for a 100 MB resource here, and there is still room for improving patching performance if really needed.
