* | ash: let $HOME set home directory of login shellRon Yorston2022-03-221-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In busybox-w32 the shell option '-l' sets HOME to the user's home directory, as determined by a call to GetUserProfileDirectory(). This is differs from how shells work on Unix, where HOME is usually set by login(1). Allow the user to override this behaviour by setting HOME before starting the shell. If HOME isn't set or contains an empty string the previous behaviour applies. If HOME is set to a non-empty string the user should ensure that it represents a valid absolute path. (GitHub issue #244)
* | Fix POSIX buildFRP-4621-gf3c5e8bc3Ron Yorston2022-02-271-2/+2
| | | | | | | | | | Commit e6238530e (cpio: code shrink with !FEATURE_EXTRA_FILE_DATA) broke the POSIX build by incorrectly excluding chunks of code.
* | ash: try harder to avoid ctrl-c issueRon Yorston2022-02-271-24/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 96a647690 (ash: prevent issue with ctrl-c and echo in loop) attempted to fix the problem that interrupting a loop like: while true; do echo hello; done caused the shell to exit. However, it wasn't completely effective and it only applied to echo and printf, not other builtins. Revert 96a647690 and instead don't call raise_interrupt() from crtl_handler() for the foreground interactive shell.
* | win32: fake file ownership on FAT filesystemsRon Yorston2022-02-171-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | busybox-w32 tries to display the ownership of files by comparing the security identifier (SID) of the current user with that of the file on disk. For filesystems that don't support SIDs this resulted in files being listed as owned by root. It appears that filesystems without support for file ownership return a null SID. In such cases pretend the file belongs to the current user. GitHub issue #241.

* | ash: workaround for UCRT bugRon Yorston2022-02-121-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There seems to be a bug in UCRT such that if a process has been started by passing a non-NULL environment block to CreateProcess() any subsequent call to spawnve() with a non-NULL environment pointer results in a crash. Commit 5b48ca53b (win32: pass NULL to spawnve, not environ) fixed the problem in busybox-w32 for those cases where a NULL environment pointer was sufficient. It didn't handle the case where the shell passes a modified environment to its child. All calls to spawnve() in the shell occur in a process which will terminate whether or not the call succeeds. It therefore doesn't matter if we mess with the environment of this process to allow spawnve() to be passed a NULL environment pointer. Do this for UCRT builds only. (GitHub issue #234)
* | cpio: code shrink with !FEATURE_EXTRA_FILE_DATARon Yorston2022-02-102-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The new --renumber-inodes option won't work if FEATURE_EXTRA_FILE_DATA is disabled. Don't allow it to be selected in that case. In fact, if FEATURE_EXTRA_FILE_DATA is disabled all the code to handle hardlinks can be #ifdef'ed out. The new --ignore-devno option need do nothing if FEATURE_EXTRA_FILE_DATA is disabled, as in that case the device ids will already be zero. It can still be selected, cpio will just always behave as though the option was provided on the command line. This doesn't affect the size of the default build.
* | find: -samefile requires FEATURE_EXTRA_FILE_DATARon Yorston2022-02-091-1/+1
| | | | | | | | | | Without FEATURE_EXTRA_FILE_DATA we don't have inode numbers to match so -samefile won't work.
