build system: use SOURCE_DATE_EPOCH for timestamp if available

2021-06-05T16:13:00+00:00

The SOURCE_DATE_EPOCH is an effort of the Reproducible Builds organization to make timestamps/build dates in compiled tools deterministic over several repetitive builds. Busybox shows by default the build date timestamp which changes whenever compiled. To have a reasonable accurate build date while staying reproducible, it's possible to use the *date of last source modification* rather than the current time and date. Further information on SOURCE_DATE_EPOCH are available online [1]. This patch modifies `confdata.c` so that the content of the SOURCE_DATE_EPOCH env variable is used as timestamp. To be independent of different timezones between builds, whenever SOURCE_DATE_EPOCH is defined the GMT time is used.

gen_build_files: Use C locale when calling sed on globbed files

2021-06-05T15:36:19+00:00

When include/applets.h is re-generated it generates code macros in include/applets.h e.g. IF_XZCAT(APPLET_ODDNAME(xzcat, unxz, BB_DIR_USR_BIN, BB_SUID_DROP, xzcat)) ... IF_CHVT(APPLET_NOEXEC(chvt, chvt, BB_DIR_USR_BIN, BB_SUID_DROP, chvt)) ... sed is used to process source files like below to feed into this header generation sed -n 's@^//applet:@@p' "$srctree"/*/*.c "$srctree"/*/*/*.c this means we let shell decide the order of .c files being fed into sed tool, applets.h has code snippets thats generated out of code fragments from these .c files and the order of the generated code depends on the order of .c files being fed to sed and then piped to generate tool, even though the generated code is logically same, it does result in re-odered code in applets.h based on which shell was used during build on exact busybox sources since sort order is different based on chosen locale and also default shell being bash or dash This sets the environment variable LC_ALL to the value C, which will enforce bytewise sorting, irrespective of the shell Signed-off-by: Khem Raj Signed-off-by: Denys Vlasenko

build system: avoid build failure during bisection

2021-04-13T16:26:46+00:00

Commit 4bdc914ff (build system: fix compiler warnings) added a test on the return value of fgets() in split-include.c. During bisection it's possible to go back to a state where a configuration value didn't exist. This results in an empty include file corresponding to the missing feature. If a subsequent bisection returns to a state where the feature exists split-include treats the empty file as an error and the build fails. Add a call to ferror() to distinguish between fgets() failing due to an error and due to there being no data to read. Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko
