libarchive: alter handling of failure to create symlinks

2022-09-27T10:18:29+00:00

Unlike GNU tar upstream BusyBox tar treats all errors as fatal. Failure to create a symlink on Windows is very likely due to a lack of the required privilege. busybox-w32 therefore treats this case as a non-fatal error and, as far as possible, continues extracting files. However: - The inconsistency of this behaviour caused some confusion. - busybox-w32 tar didn't return an error status when a non-fatal error was encountered, unlike GNU tar. Change the implementation so extraction continues when symlink creation fails but the error report is deferred until all of the archive has been processed. Only one error is reported and it's treated as fatal. Saves 48-64 bytes. (GitHub issue #265)

libarchive/get_header_ar.c: fix extraction of archives from binutils in deterministic mode
