build: handle directory with whitespace in AUTOREMOVE clean

2022-12-04T16:18:37Z

Package with whitespace in their build directory are not correctly removed when CONFIG_AUTOREMOVE is enabled. This is caused by xargs that use whitespace as delimiters. To handle this use \0 as the delimiter and set find to use \0 as the delimiter. Signed-off-by: Christian Marangi (cherry picked from commit dccee21792b89031bcd801030de403f195d80278)

build: make find_md5 reproducible with AUTOREMOVE

2022-12-04T15:07:33Z

While experimenting with the AUTOREMOVE option in search of a way to use prebuilt host tools in different buildroot, it was discovered that the md5 generated by find_md5 in depends.mk is not reproducible. Currently the hash is generated by the path of the file in addition to the file mod time. Out of confusion, probably, there was an idea that such command was used on the package build_dir. Reality is that this command is run on the package files. (Makefile, patches, src) This is problematic because the package Makefile (for example) change at each git clone and base the hash on the Makefile mtime doesn't really reflect if the Makefile actually changes across a buildroot or not. A better approach is to generate an hash of each file and then generate an hash on the sort hash list. This way we remove the problem of git clone setting a wrong mtime while keeping the integrity of checking if a file changed for the package as any change will result in a different hash. Introduce a new kind of find_md5 function, find_md5_reproducible that apply this new logic and limit it only with AUTOREMOVE option set to prevent any kind of slowdown due to additional hash generation.

download: handle possibly invalid local tarballs

2020-11-27T13:46:13Z

Currently it's assumed, that already downloaded tarballs are always fine, so no checksum checking is performed and the tarball is used even if it might be corrupted. From now on, we're going to always check the downloaded tarballs before considering them valid. Steps to reproduce: 1. Remove cached tarball rm dl/libubox-2020-08-06-9e52171d.tar.xz 2. Download valid tarball again make package/libubox/download 3. Invalidate the tarball sed -i 's/PKG_MIRROR_HASH:=../PKG_MIRROR_HASH:=ff/' package/libs/libubox/Makefile 4. Now compile with corrupt tarball source make package/libubox/{clean,compile} Signed-off-by: Petr Štetiar

build: improve ccache support

2020-07-11T13:19:53Z

Set CCACHE_DIR to $(TOPDIR)/.ccache and CCACHE_BASEDIR to $(TOPDIR). This allows to do clean and dirclean. Cache hit rate for test build after dirclean is ~65%. If CCACHE is enabled stats are printed out at the end of building process. CCACHE_DIR config variable allows to override default, which could be useful when sharing cache with many builds. cacheclean make target allows to clean the cache. Changes from v1: - remove ccache directory using CCACHE_DIR variable - remove ccache leftovers from sdk and toolchain make files - introduce CONFIG_CCACHE_DIR variable - introduce cacheclean make target Signed-off-by: Roman Yeryomin
