      ar.pm: Tell user that GNU ar could not set the symbol table's mtime · a9824cd6

... in verbose mode, when setting it.

In other words tell the user when GNU ar cannot reproduce the output of
strip-nondeterminism.

      ar.pm: Add test files for symtab ('/') and long names ('//') · f54aa08f
      Marc Herbert authored and Chris Lamb's avatar Chris Lamb committed 
      

Note symbol_table.out cannot be produced by GNU ar alone because it can't set
any specified timestamp on the symbol table.

long_member_name.a.out cannot be created by GNU ar alone either for a
completely different, strange and permission-related reason.  Faking a
specified timestamp for archive members is easy pre-archiving with "touch -r".
However this obviously requires 'ar U'. For long filenames, ar U maps
permissions 644 to the string "100644" for some unknown reason. Both ar D and
strip-nondeterminism use the permission string "644" (displayed by diffoscope
as "?rw-r--r--")

This is the script which was used to create these test files:

create_ar_testcase()
{
    ar_base="$1"; shift

    for o in "$@"; do
        objcopy --remove-section=.comment \
        --remove-section=.note.GNU-stack \
        --remove-section=.eh_frame \
        "$o" || true
    done
    touch "$@"

    rm -f "${ar_base}".a.in "${ar_base}".a.out "${ar_base}".a.D
    ar qU "${ar_base}".a.in "$@"

    ar qD "${ar_base}".a.D "$@"
    cp "${ar_base}".a.D "${ar_base}".a
    strip-nondeterminism --normalizers +all -v -T 1423159771 "${ar_base}".a
    mv "${ar_base}".a "${ar_base}".a.out
}
