| * ash: regressions in process substitutionRon Yorston2021-09-021-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stacy Harper reports that this script: test() { . /tmp/bb_test; } echo "export TEST=foo" >/tmp/bb_test test 2>/dev/null echo "$TEST" correctly prints 'foo' in BusyBox 1.33 but hangs in 1.34. Bisection suggested the problem was caused by commit a1b0d3856 (ash: add process substitution in bash-compatibility mode). Removing the call to unwindredir() in cmdloop() introduced in that commit makes the script work again. Additionally, these examples of process substitution: while true; do cat <(echo hi); done f() { while true; do cat <(echo hi); done } f result in running out of file descriptors. This is a regression from v5 of the process substitution patch caused by changes to evalcommand() not being transferred to v6. function old new delta static.pushredir - 99 +99 evalcommand 1729 1750 +21 exitreset 69 86 +17 cmdloop 372 365 -7 unwindredir 28 - -28 pushredir 112 - -112 ------------------------------------------------------------------------------ (add/remove: 1/2 grow/shrink: 2/1 up/down: 137/-147) Total: -10 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* | ash: code shrink ps_cmdRon Yorston2021-09-081-6/+12
| | | | | | | | | | | | | | The ps_cmd member of struct procstat isn't used in the WIN32 port. Remove references to it. Saves 80 bytes.
* | ash: code shrinkRon Yorston2021-09-051-10/+6
| | | | | | | | | | | | Tweak the code to handle /etc/profile. Looks tidier and saves 8 bytes.
* | ash: restrict valid job idsRon Yorston2021-09-051-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | Although job control is disabled in busybox-w32 getjob() is still compiled in because it's used by waitcmd(). Job ids of the form '%string' or '%?string' don't work, though, because the command isn't stored in the job structure. Disable the code to handle them. Job ids '%%', '%+', '%-' and '%num' are still allowed and some of them are (successfully) used in the ash tests. Saves 144 bytes.
* | ash: omit handling of stopped jobsRon Yorston2021-09-051-1/+10
| | | | | | | | | | | | | | Since Windows doesn't really know about stopped jobs don't bother to compile some code that deals with them. Saves 120 bytes.

| | | | | | | | | | | | Reduce amount of wasted space in the signals[][] array. Saves 48 bytes.

* | win32: fix entropy collection for isaacRon Yorston2021-09-021-20/+10
| | | | | | | | | | | | | | | | | | The condition to detect the end of the environment string was wrong. Don't bother calculating the MD5SUM of the environment, just XOR the bytes into the data. This reduces bloat by 320 bytes but only in the non-default case.
* | config: turn off DEBUG in default buildsRon Yorston2021-08-312-2/+2

* | vi: add fileformats optionRon Yorston2021-08-303-17/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a limited version of the 'fileformats' option. Only the 'dos,unix' and 'unix,dos' settings are allowed with the former as default. When a file is read for editing its format is detected. If it only has LF line endings it's treated as being of type 'unix' otherwise its type is 'dos'. When an empty edit buffer is created it's given the first file type listed in 'fileformats'. The file type is stored in the read-only option 'fileformat' and is used to select the appropriate line endings when the file is written. See GitHub issue #220. Adds 168 bytes to the binary.

Addresses are limited to the number of lines in the file so a command like ':2000000000' (go to the two billionth line) no longer causes a long pause. Improved vi compatibility of '+' and '-' operators that aren't followed immediately by a number: :4+++= 7 :3-2= 1 :3 - 2= 4 (yes, really!) In a command like ':,$' the empty address before the separator now correctly refers to the current line. (The similar case ':1,' was already being handled.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A user noted that the following command was slower than they expected: busybox shuf -i "1500000000-$(date +%s)" -n 5 At time of writing the range contains 128 million values. On my system this takes 7.7s whereas 'shuf' from coreutils takes a handful of milliseconds. Optimise BusyBox 'shuf' for cases where -n is specified by stopping shuffling once the required number of lines have been processed. On my system the time for the example is reduced to 0.4s. function old new delta shuf_main 520 540 +20 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 20/0) Total: 20 bytes v2: Code shrink.

| | | | | | | | | | | | | | | | Turn off the 'if-conversion' optimisation for err_win_to_posix(). My tests actually have this being slightly faster than with the optimisation enabled, though within the variation of the measurement. Saves 288 bytes.
* | vi: skip permission check on .exrcRon Yorston2021-08-221-0/+4
| | | | | | | | | | POSIX requires that the .exrc file is only writable by its owner. Our bogus permissions can't confirm this so just skip the test.

This doesn't seem particularly helpful and it upsets the calculation of the width of the message in show_status_line(). Use '?' rather than '.' for unprintable characters. - Newlines in the string were displayed as both '^J' and '$', which is somewhat redundant. function old new delta not_implemented 199 108 -91 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-91) Total: -91 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The '/' and '?' search commands wrap to the other end of the buffer if the search target isn't found. When searches are used to specify addresses in colon commands they should do the same. (In traditional vi and vim this behaviour is controlled by the 'wrapscan' option. BusyBox vi doesn't have this option and always uses the default behaviour.) function old new delta colon 4033 4077 +44 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 44/0) Total: 44 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
