Commit 8baa643a3 (lineedit: match local directories when searching PATH) included subdirectories of the current directory in the search when tab-completing commands. Unfortunately a short time later commit 1d180cd74 (lineedit: use strncmp instead of is_prefixed_with (we know the length)) broke this feature by returning an incorrect length for the array of paths.

2022-08-22libbb: make '--help' handling more consistentRon Yorston
Running an applet with '--help' as its only argument is treated as a special case. If additional arguments follow '--help' the behaviour is inconsistent: - applets which call single_argv() print help and do nothing else; - applets which call getopt() report "unrecognized option '--help'" and print help anyway; - expr says "expr: syntax error" and doesn't print help; - printenv silently ignores '--help', prints any other variables and doesn't print help; - realpath says "--help: No such file or directory", prints the path of any other files and doesn't print help. If the first argument is '--help' ignore any other arguments and print help. This is more consistent and most likely what the user wanted. See also commit 6bdfbc4cb (libbb: fix '--help' handling in FEATURE_SH_NOFORK=y). function old new delta show_usage_if_dash_dash_help 75 69 -6 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-6) Total: -6 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2022-07-03lineedit: get PWD from ashRon Yorston
The line editing code and ash disagree when the current directory is changed to a symbolic link: ~ $ mkdir real ~ $ ln -s real link ~ $ cd link ~/real $ pwd /home/rmyf36/link Note the prompt says we're in ~/real. Bash does: [rmy@random ~]$ cd link [rmy@random link]$ pwd /home/rmyf36/link Ash uses the name supplied by the user while the line editing code calls getcwd(3). The discrepancy can be avoided by fetching the value of PWD from ash. Hush calls getcwd(3) when the directory is changed so there's no disagreement with the line editing code. There is no standard how shells should handle cd'ing into symlinks. function old new delta parse_and_put_prompt 838 869 +31 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2022-06-26ash,hush: use HOME for tab completion and promptsRon Yorston
ash and hush correctly use the value of HOME for tilde expansion. However the line editing code in libbb obtains the user's home directory by calling getpwuid(). Thus tildes in tab completion and prompts may be interpreted differently than in tilde expansion. When the line editing code is invoked from a shell make it use the shell's interpretation of tilde. This is similar to how GNU readline and bash collaborate. function old new delta get_homedir_or_NULL 29 72 +43 optschanged 119 126 +7 hush_main 1204 1211 +7 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 57/0) Total: 57 bytes v2: Always check for HOME before trying the password database: this is what GNU readline does.

2022-06-26libbb: restore special handling of nomsg errorsRon Yorston
The functions bb_perror_nomsg() and bb_perror_nomsg_and_die() are used to print error messages where no specific information is available. For example: $ busybox mktemp -p / mktemp: (null): Permission denied mktemp(3) doesn't tell us the name of the file it tried to create. However, printing '(null)' is a regression introduced by commit 6937487be (libbb: reduce the overhead of single parameter bb_error_msg() calls). Restore the previous behaviour by reverting the changes to the two functions mentioned: $ busybox mktemp -p / mktemp: Permission denied function old new delta bb_perror_nomsg_and_die 7 14 +7 bb_perror_nomsg 7 14 +7 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 14/0) Total: 14 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
