* build system: Make it possible to build with 64bit time_tUwe Kleine-König2023-05-072-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | On most 32bit architectures time_t (and a few other time related types) are a signed 32bit wide integer type. As a consequence they can only represent dates between Fri Dec 13 08:45:52 PM UTC 1901 (-0x80000000 seconds before Jan 1 1970) and Tue Jan 19 03:14:07 AM UTC 2038 (0x7fffffff seconds after Jan 1 1970). Given that some machines that are built today have an expected lifetime of >15 years, this needs to be extended. To to that, define the cpp symbol _TIME_BITS to 64 which results in some magic in glibc to make time_t (and the few other time related types) 64 bit wide. This new switch CONFIG_TIME64 is in the spirit of CONFIG_LFS and only expected to have the expected effect with glibc. On musl for examples time_t already defaults to 64bit wide types.

* readlink: support --, -n alwaysEric Blake2023-04-161-17/+12
| | | | | | | | | | | | | | | | | | | | | | | POSIX will be standardizing readlink (just the -n option) and realpath (just -E and -e options): https://www.austingroupbugs.net/view.php?id=1457 Change things for readlink so that the POSIX-mandated -n and -- work even when disabling the non-standard (and partially non-working) -f when FEATURE_READLINK_FOLLOW is clear. POSIX also wants readlink to be verbose by default (if the argument is not a symlink, readlink must output a diagnostic); I did NOT address that one, because I'm waiting to see what the GNU Coreutils folks do: https://lists.gnu.org/archive/html/bug-coreutils/2023-03/msg00035.html Partial fix for https://bugs.busybox.net/show_bug.cgi?id=15466 function old new delta packed_usage 34538 34557 +19 Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | The trap and jobs builtins can be used to report information about traps and jobs. This works when they're called from the current shell but in a child shell the required information is usually cleared. Special hacks allow: - trap to work with command substitution; - jobs to work with command substitution or in a pipeline. Neither works with process substitution. - Relax the test for the trap hack so it also supports pipelines. - Pass the command to be evaluated to forkshell() in evalbackcmd() so trap and jobs both work with process substitution. function old new delta forkchild 629 640 +11 argstr 1502 1496 -6 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 11/-6) Total: 5 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | Commit 1d37186fe2 (ash: add bash-compatible EPOCH variables) added support for the EPOCHSECONDS and EPOCHREALTIME variables. These variables are dynamic and therefore require the VDYNAMIC flag to be non-zero. However, this is only the case if support for the RANDOM variable is enabled. Give VDYNAMIC a non-zero value if either EPOCH variables or RANDOM are enabled. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
