2021-12-29ed: add support for -s command-line option as mandated by POSIXSören Tempel
Apart from the -p option, POSIX also mandates an -s option which suppresses the output of byte counts for the e, E, r, and w command. From these commands, Busybox ed presently only implements the r and w commands. This commit ensures that these two command do not output any bytes counts when the -s option is passed. The shell escape command, also effected by the -s option, is not implemented by Busybox at the moment. function old new delta packed_usage 34096 34115 +19 doCommands 1887 1900 +13 readLines 388 397 +9 .rodata 104196 104200 +4 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 45/0) Total: 45 bytes Signed-off-by: Sören Tempel <soeren+git@soeren-tempel.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-12-25sed: do not ignore 'g' modifier when match starts with ^Dominique Martinet
It is perfectly valid to start a regex with ^ and have other patterns with \| that can match more than once, e.g. the following example should print ca, as illustrated with gnu sed: $ echo 'abca' | sed -e 's/^a\|b//g' ca busybox before patch: $ echo 'abca' | busybox sed -e 's/^a\|b//g' bca busybox after patch: $ echo 'abca' | ./busybox sed -e 's/^a\|b//g' ca regcomp handles ^ perfectly well as illustrated with the second 'a' that did not match in the example, we ca leave the non-repeating to it if appropriate. The check had been added before using regcomp and was required at the time (f36635cec6da) but no longer makes sense now.

2021-12-19ed: align output of read command with POSIX.1-2008Sören Tempel
POSIX.1-2008 mandates the following regarding the read command: If the read is successful, and -s was not specified, the number of bytes read shall be written to standard output in the following format: "%d\n", <number of bytes read> This commit aligns the output of busybox ed with POSIX.1-2008 by removing the file name from the output for the read command. This slipped through in 4836a0708fd0aaeb82871a3762b40fcf4b61e812. function old new delta .rodata 104203 104196 -7 readLines 409 388 -21 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-28) Total: -28 bytes Signed-off-by: Sören Tempel <soeren+git@soeren-tempel.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-12-19ed: fix current line number for file passed via the command-lineSören Tempel
POSIX.1-2008 mandates the following regarding the file command-line argument: If the file argument is given, ed shall simulate an e command on the file named by the pathname […] The specification for the e command mandates the following behaviour regarding the current line number in POSIX.1-2008: The current line number shall be set to the address of the last line of the buffer. However, without this commit, busybox ed will set the current line number to 1 if a file is given on the command-line and this file is not empty (lastNum != 0). This is incorrect and fixed in this commit by not modifying the current line number in ed_main(). As such, the current line number will be zero for empty files and otherwise be set to the address of the last line of the buffer. function old new delta ed_main 144 128 -16 Signed-off-by: Sören Tempel <soeren+git@soeren-tempel.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-12-17ed: add support for -p command-line option as mandated by POSIXSören Tempel
The POSIX.1-2008 specification of ed(1) mandates two command-line options: -p (for specifying a prompt string) and -s (to suppress writing of byte counts). This commit adds support for the former. Furthermore, it also changes the default prompt string to an empty string (instead of ": ") since this is also mandated by POSIX: -p string Use string as the prompt string when in command mode. By default, there shall be no prompt string. function old new delta ed_main 112 144 +32 packed_usage 34074 34097 +23 doCommands 1889 1887 -2 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/1 up/down: 55/-2) Total: 53 bytes Signed-off-by: Sören Tempel <soeren+git@soeren-tempel.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

The '%' character in a format specification may be followed by one or more flags from the list "+- #0". BusyBox printf didn't support the '0' flag or allow multiple flags to be provided. As a result the formats '%0*d' and '%0 d' were considered to be invalid.

To check if libcrypt and librt are available, we check if we can compile and link a simple test program. These checks do not match the actual linking if CONFIG_STATIC is enabled. For CONFIG_STATIC, CFLAGS_busybox is set to -static. The checks don't use CFLAGS_busybox and detect a shared libcrypt or librt. If we link busybox later and we have no static libcrypt or librt, linking will fail. Update the libcrypt and librt checks to use CFLAGS_busybox.
