This reduces initial traffic to NTP servers when a lot of devices boot at once.

2021-02-23lineedit: support empty PATH entries in tab completionRon Yorston
Zero-length path prefixes can be specified in PATH as a leading or trailing colon or two adjacent colons. POSIX says that the use of zero-length prefixes to refer to the current directory is a legacy feature. Nonetheless the shells in BusyBox respect this feature, as does 'which'. Tab-completion of executables using PATH should support this too. function old new delta complete_cmd_dir_file 934 931 -3 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-3) Total: -3 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-02-18libbb: fix '--help' handling in FEATURE_SH_NOFORK=yDenys Vlasenko
Most BusyBox applets respond to the '--help' option by printing a usage message. This is normally handled by busybox_main() so applet main routines don't have support for '--help'. In standalone shell mode with FEATURE_SH_NOFORK enabled nofork applets are invoked directly, bypassing busybox_main(). This results in inconsistent handling of '--help': - applets which call getopt() report "unrecognized option '--help'" and print help anyway; - realpath says "--help: No such file or directory" and doesn't print help; - usleep says "invalid number '--help'" and doesn't print help. Avoid inconsistency by checking for '--help' in run_nofork_applet(). Bug found by Ron Yorston. function old new delta show_usage_if_dash_dash_help - 70 +70 run_nofork_applet 347 362 +15 run_applet_no_and_exit 432 365 -67 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 1/1 up/down: 85/-67) Total: 18 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-02-07Makefile.flags: fix the OS detection for libresolvMartin Kaiser
054493350 ("Do not add -lresolv on non-Linux systems") adds a condition to link with libresolv only on linux systems. The check requires that CONFIG_UNAME_OSNAME equals Linux. This works only if the uname applet is enabled. Otherwise, CONFIG_UNAME_OSNAME is empty, regardless of the platform. By default, CONFIG_UNAME_OSNAME is the output of uname -o. For most linux systems, uname -o returns "GNU/Linux" and the check fails. In this case, linking a static busybox fails because of missing symbols from libresolv. networking/lib.a(nslookup.o): In function `add_query': nslookup.c:789: undefined reference to `__res_mkquery' networking/lib.a(nslookup.o): In function `parse_reply': nslookup.c:355: undefined reference to `ns_initparse' nslookup.c:361: undefined reference to `ns_parserr' nslookup.c:404: undefined reference to `ns_name_uncompress' nslookup.c:418: undefined reference to `ns_get16' nslookup.c:419: undefined reference to `ns_name_uncompress' .. nslookup.c:456: undefined reference to `ns_get16' ... nslookup.c:469: undefined reference to `ns_name_uncompress' ... nslookup.c:489: undefined reference to `ns_get32' ... collect2: error: ld returned 1 exit status This patch uses the output of $CC -dumpmachine to detect the target platform for which we compile.

2021-02-02vi: fix range selection by forward character motionRon Yorston
Selection of ranges for change/delete/yank by forward character motion commands (SPACE or 'l') was incorrect. The range was always one character whereas vi allows the size of the range to be specified. Fix this by executing the motion command the required number of times. There is a complication when the range is at the end of a line. We need to distinguish between a range which excludes the last character and one which includes it. This requires comparing the actual range with that expected from the command count. (With the additional quirk that a command count of zero is equivalent to a command count of one.) function old new delta find_range 587 619 +32 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 32/0) Total: 32 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Revise the code so the index of the upper bound of the range, 'max', isn't calculated. Instead check the value of the first non-matching character to see if we've reached the end of the range. This new code speeds up the time to find a valid applet name by 6% and halves the time to detect that a given name is invalid.
