| | | | | | | | | | | | | | | | | | When icanon is set with -echo (e.g. ssh from an emacs shell) then S.state will remain null but later it will be deferenced causing ash to crash.

| | | | | | | | | | | | | | | | | | | | The functions ndelay_on(), ndelay_off() and close_on_exec_on() don't do anything useful because our fcntl(2) implementation doesn't support the features they require. Replace them with stubs. Saves 176-208 bytes.
* | ash: more Unix-style path fixesRon Yorston2023-04-161-7/+19
| | | | | | | | | | | | | | | | | | | | | | Commit 950b318a2 (ash: Unix-style paths, shell builtins and applets) broke running of Unix-style absolute paths from the shell by PATH search. The copy of the program name on the stack should only be used in the first call to tryexec() otherwise it interferes with the use of the stack by padvance(). Also, bring the code to handle Unix-style paths in find_command() into line with the revised code in shellexec().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The trap and jobs builtins can be used to report information about traps and jobs. This works when they're called from the current shell but in a child shell the required information is usually cleared. Special hacks allow: - trap to work with command substitution; - jobs to work with command substitution or in a pipeline. Neither works with process substitution. - Relax the test for the trap hack so it also supports pipelines. - Pass the command to be evaluated to forkshell() in evalbackcmd() so trap and jobs both work with process substitution. function old new delta forkchild 629 640 +11 argstr 1502 1496 -6 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 11/-6) Total: 5 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| * ash: make EPOCH variables work if RANDOM is disabledRon Yorston2023-03-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1d37186fe2 (ash: add bash-compatible EPOCH variables) added support for the EPOCHSECONDS and EPOCHREALTIME variables. These variables are dynamic and therefore require the VDYNAMIC flag to be non-zero. However, this is only the case if support for the RANDOM variable is enabled. Give VDYNAMIC a non-zero value if either EPOCH variables or RANDOM are enabled. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ash: remove ASH_IGNORE_CR config optionRon Yorston2023-04-096-33/+10
| | | | | | | | | | | | | | | | | | | | | | | | No further problems with CRLF handling have been reported. Remove the configuration option that allowed some recent changes to be turned off. Also, prevent some WIN32 code from being included in the POSIX build. The faulty code is from commit 64c8f5f3d (ash: add support for INT trap). These changes don't alter the default WIN32 build.
* | xargs: kill children when interrupted by Ctrl-CRon Yorston2023-04-071-3/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A user was running the following command in a clone of the busybox-w32 repo from a busybox-w32 shell using Git for Windows: git rev-list --all | xargs git grep main.c Using Ctrl-C to interrupt the command resulted in the familiar problem that two processes ended up competing for user input: in this case the busybox-w32 shell and the Git for Windows pager, less. Make the problem go away (in this particular case) by killing all the children of xargs when it's interrupted. This is probably a sensible thing to do for other circumstances too. Adds 64-100 bytes. (GitHub issue #306)
* | win32: ignore ctrl-c in parent of execve(2)Ron Yorston2023-04-051-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The execve(2) system call is emulated for Microsoft Windows. This requires the creation of a new process. The old process remains active, waiting for the "execed" child to exit so it can pass on its exit status. Previously this was achieved using P_WAIT mode in the call to spawnve(). However the parent of the execve(2) process may still be able to catch Ctrl-C interrupts. This can lead to unwanted behaviour, such as a shell and its children competing for input. Force the waiting process to ignore Ctrl-C interrupts. Costs 64-80 bytes. (GitHub issue #303)
* | ash: special treatment for read builtinRon Yorston2023-04-051-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When INT is being trapped the read builtin gets special treatment in bash. In a top-level interactive shell interrupting the read with Ctrl-C clears the input and allows the user to enter a new string. In a subshell Ctrl-C really does interrupt the read and the trap isn't executed. zsh works similarly, except that in the latter case the trap is executed. dash interrupts the read and executes the trap in both cases. ksh also interrupts the read in both cases but only executes the trap in the first. Implement the bash behaviour. (GitHub issue #303)
* | ash: reinstate fix for ctrl-c issueRon Yorston2023-04-051-1/+1
| | | | | | | | | | Reinstate the change introduced in commit 96c104a61c (ash: try harder to avoid ctrl-c issue). It was removed during recent work on traps.
* | ash: add support for INT trapRon Yorston2023-04-033-10/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The trap builtin now handles INT. As before, other signals (from a limited list) are accepted but their traps don't have any effect. There's some variability in how shells handle traps. This patch upholds that proud tradition. Various changes are needed to make this work: - Line editing has a new flag to ignore Ctrl-C. - If INT is being trapped or ignored don't call raise_interrupt(). - A minimal implementation of dotrap() is provided. - Call dotrap() when the read builtin or line input detect Ctrl-C. - Adjust Ctrl-C detection when the INT trap is changed. - Set may_have_traps when an INT trap is set. Costs 368-448 bytes. (GitHub issue #303)
* | win32: add fake HUP and QUIT signalsRon Yorston2023-04-032-2/+4
| | | | | | | | | | | | | | | | | | | | | | It's fairly common for shell scripts to trap this set of signals: EXIT HUP INT QUIT TERM (or the numeric equivalent: 0 1 2 3 15) Add definitions for SIGHUP and SIGQUIT. We don't take any action if traps are defined for them, but at least scripts won't fail. (GitHub issue #303)
* | ash: fix POSIX buildRon Yorston2023-04-031-0/+2
| | | | | | | | | | | | Commit 950b318a2 (ash: Unix-style paths, shell builtins and applets) added a call to stack_add_ext_space() which should only be included when building for Microsoft Windows.
