2021-06-16vi: reject change command when motion failsRon Yorston
If the motion command used to define the range of a change, yank or delete fails the whole command should be rejected. BusyBox vi already handled failed searches in these circumstances. Add some more cases: - non-existent mark: d'x - movement beyond end of file: c99999+ or 99999<< This is implemented using a global variable which is set when a command error is detected. Unlike the case of motion within a line it's insufficient to check that the motion command doesn't move the cursor: this fails to process 'LyL' correctly, for example, as the second 'L' doesn't move the cursor. function old new delta indicate_error 75 82 +7 find_range 686 692 +6 do_cmd 4851 4852 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 14/0) Total: 14 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-06-16vi: up/down motion beyond end of file should failRon Yorston
In traditional vi and vim line motion commands ('+'/'-'/'j'/'k') fail if the movement would exceed the bounds of the file. BusyBox vi allowed such commands to succeed, leaving the cursor on the first or last character of the file. Make BusyBox vi work like vi/vim. For the 'G'/'H'/'L' commands traditional vi treats an out of bounds result as an error, vim doesn't. BusyBox vi behaves like vim, both before and after this patch. function old new delta do_cmd 4785 4851 +66 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 66/0) Total: 66 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-06-05build system: use SOURCE_DATE_EPOCH for timestamp if availablePaul Spooren
The SOURCE_DATE_EPOCH is an effort of the Reproducible Builds organization to make timestamps/build dates in compiled tools deterministic over several repetitive builds. Busybox shows by default the build date timestamp which changes whenever compiled. To have a reasonable accurate build date while staying reproducible, it's possible to use the *date of last source modification* rather than the current time and date. Further information on SOURCE_DATE_EPOCH are available online [1]. This patch modifies `confdata.c` so that the content of the SOURCE_DATE_EPOCH env variable is used as timestamp. To be independent of different timezones between builds, whenever SOURCE_DATE_EPOCH is defined the GMT time is used.

2021-06-05shell: also do word splitting when -d DELIM is usedEicke Herbertz
The original commit 3bef5d89b0 introduced an additional check for an unset `opt_d` before doing word splitting. I'm unsure why it's there in the first place, but the commit message also describes a different behaviour than what -d actually does in bash, while the code mostly does the right thing. `opt_d` sets the line delimiter for read to stop reading and should not affect word splitting.

2021-06-05gen_build_files: Use C locale when calling sed on globbed filesKhem Raj
When include/applets.h is re-generated it generates code macros in include/applets.h e.g. IF_XZCAT(APPLET_ODDNAME(xzcat, unxz, BB_DIR_USR_BIN, BB_SUID_DROP, xzcat)) ... IF_CHVT(APPLET_NOEXEC(chvt, chvt, BB_DIR_USR_BIN, BB_SUID_DROP, chvt)) ... sed is used to process source files like below to feed into this header generation sed -n 's@^//applet:@@p' "$srctree"/*/*.c "$srctree"/*/*/*.c this means we let shell decide the order of .c files being fed into sed tool, applets.h has code snippets thats generated out of code fragments from these .c files and the order of the generated code depends on the order of .c files being fed to sed and then piped to generate tool, even though the generated code is logically same, it does result in re-odered code in applets.h based on which shell was used during build on exact busybox sources since sort order is different based on chosen locale and also default shell being bash or dash This sets the environment variable LC_ALL to the value C, which will enforce bytewise sorting, irrespective of the shell Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-06-05udhcpc: revert deprecation message for -VDenys Vlasenko
"-x vendor:VENDOR" will not be a trivial replacement of it: (1) by default, we do send a vendor string ("udhcp BB_VER"), will need code to preserve the default. (2) -V '' currently disables vendor string. -x vendor:'' would not easily achieve that: it adds no option at all (string options can't be empty), and default (1) would trigger. To avoid that, we will need yet another hack to detect -x vendor:'' and interpret that as "no vendor string at all".
