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>

Use a NULL value of maxsz_p to indicate to xmalloc_fgets_internal() that the caller doesn't care about the maximum size of the buffer.

2021-02-02libbb: code shrink and speed up index_in_strings()Ron Yorston
Rewrite index_in_strings() to replace calls to strcmp()/strlen(). With this change searching for valid names in the applet_names array (for example) is 40% faster. The code has to assume the strings aren't sorted, so will always scan the entire array when presented with an invalid name. function old new delta index_in_strings 63 56 -7 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-7) Total: -7 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-02-02libbb: code shrink and speed up find_applet_by_name()Ron Yorston
find_applet_by_name() determines the appropriate range of applet indices to check for the given name and performs a linear search in applet_names[]. 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. The average time to detect an invalid name is now the same as for a valid one. function old new delta find_applet_by_name 155 133 -22 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-22) Total: -22 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
