ccache 3.2.2 发布,此版本主要包括以下更新:

新特性及性能改善:

  • Added support for CCACHE_COMPILERCHECK=string:<value>. This is a faster alternative to CCACHE_COMPILERCHECK=<command> if the command’s output can be precalculated by the build system.      

  • Add support for caching code coverage results (compiling for gcov).      

Bug 修复:

  • Fixed bug which could result in false cache hits when source code contains '"' followed by " /*" or " //" (with variations).      

  • Made hash of cached result created with and without CCACHE_CPP2 different. This makes it possible to rebuild with CCACHE_CPP2 set without having to clear the cache to get new results.      

  • Don’t try to reset a non-existing stats file. This avoids “No such file or directory” messages in the ccache log when the cache directory doesn’t exist.      

  • Fixed a bug where ccache deleted clang diagnostics after compiler failures.      

  • Avoid performing an unnecessary copy of the object file on a cache miss.      

  • Bail out on too hard compiler option -fmodules.      

  • Bail out on too hard compiler option -fplugin=libcc1plugin (interaction with GDB).      

  • Fixed build error when compiling ccache with recent clang versions.      

  • Removed signal-unsafe code from signal handler.      

  • Corrected logic for when to output cached stderr.      

  • Wipe the whole cached result on failure retrieving a cached file.      

  • Fixed build error when compiling ccache with recent clang versions.

ccache(“compiler cache”的缩写)是一个编译器缓存,该工具会高速缓存编译生成的信息,并在编译的特定部分使用高速缓存的信息, 比如头文件,这样就节省了通常使用 cpp 解析这些信息所需要的时间。如果您编译清单 2 中的文件,假定    foobar.h中包含对其他头文件的引用,ccache 会用那个文件的 cpp-parsed 版本来 取代              include声明。就那么简单。不是真正去读取、理解并解释其内容,ccache 只是 将最终的文本拷贝到文件中,使得它可以立即被编译。
