build: make find_md5 reproducible with AUTOREMOVE

2022-09-30T20:26:51Z

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.

depends.mk: fix typo in rdep function

2022-09-11T09:07:53Z

Just like later in the file, the precursor to _check _check.1 is supposed to be moved to _check before it is touched. This line would error if it was ever run. Signed-off-by: Michael Pratt

build: introduce $(MKHASH)

2021-05-13T13:13:15Z

Before this commit, it was assumed that mkhash is in the PATH. While this was fine for the normal build workflow, this led to some issues if make TOPDIR="$(pwd)" -C "$pkgdir" compile was called manually. In most of the cases, I just saw warnings like this: make: Entering directory '/home/.../package/gluon-status-page' bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found [...] While these were only warnings and the package still compiled sucessfully, I also observed that some package even fail to build because of this. After applying this commit, the variable $(MKHASH) is introduced. This variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the correct path. Signed-off-by: Leonardo Mörlein

build: find_md5 list with mod time and sorted

2020-12-07T20:55:59Z

It was observed that the MD5 would not change after source files had been modified, looking deeper into the build process it was discovered that find_md5 build function makes a list of the files being built and then passes the list to a summing utility on stdin. The resultant MD5 is of the file list, not the contents of the files. The MD5 would change if the ordering of the list changed, or items were removed or deleted. The proposed fix is to add the modification time after the filename and then sort the list to prevent find returning files in a different order falsely re-triggering a rebuild. The MD5 will now change when a file is modified or files are added/removed from the list. Using 'T@' to show time in epoch for timezone independent behaviour. Signed-off-by: John Beckett

build: stage unstripped packages inside PKG_BUILD_DIR

2017-01-18T22:57:08Z

This makes the build slightly more efficient by avoiding the need to re-stage packages on every full build run. It is also necessary for the upcoming CONFIG_AUTOREMOVE feature Signed-off-by: Felix Fietkau
