| | | | | | | | | | | | When the user tries to exit an interactive shell with stopped jobs present the shell issues a warning and only exits if the user insists by trying to exit again.

* ash: fix ignoreeof optionRon Yorston2021-09-141-19/+3
| | | | | | | | | | | | | | | | | | | | The ignoreeof option should prevent an interactive shell from exiting on EOF. This hasn't worked in BusyBox ash since commit 727752d2d (ash: better fix for ash -c 'echo 5&' and ash -c 'sleep 5&' with testcase). Commit 3b4d04b77e (ash: input: Allow two consecutive calls to pungetc) pulled in improved support for multiple calls to pungetc from dash, thus rendering much of commit 727752d2d obsolete. Removing this old code fixes the problem with ignoreeof. function old new delta __pgetc 605 587 -18 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-18) Total: -18 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* ash: parser: Get rid of PEOADenys Vlasenko2021-09-081-131/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream commit: Date: Wed, 27 May 2020 12:19:13 +1000 parser: Get rid of PEOA PEOA is a special character used to mark an alias as being finished so that we don't enter an infinite loop with nested aliases. It complicates the parser because we have to ensure that it is skipped where necessary and not copied to the resulting token text. This patch removes it and instead delays the marking of aliases until the second pgetc. This has the same effect as the current PEOA code while keeping the complexities within the input code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream commit: Date: Tue, 28 Apr 2020 01:15:26 +1000 parser: Fix handling of empty aliases Dash was incorrectly handling empty aliases. When attempting to use an empty alias with nothing else, I'm (incorrectly) prompted for more input: ``` $ alias empty='' $ empty > ``` Other shells (e.g., bash, yash) correctly handle the lone, empty alias as an empty command: ``` $ alias empty='' $ empty $ ``` The problem here is that we incorrectly enter the loop eating TNLs in readtoken().

Thanks for the report. This is actually a fairly old bug with set -e that's just been exposed by the exit status change. What's really happening is that cleanup itself is triggering a set -e exit incorrectly because evaltree cached the value of eflag prior to the function call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
