2025-12-08ash: Extend ARM msvcrt workaround to 32 bit ARM tooMartin Storsjö1-1/+1
The fact that "environ" is not assignable goes the same for both 32 and 64 bit ARM on msvcrt - this is not an issue on UCRT as noted in c44f23f4acbbd854eccd962110e41343d8f03296. This extends the original workaround from ea8742bc1657cd0aae32ac555560c8228795488f to 32 bit ARM too.
2025-12-02win32: add a config for 32-bit build with UnicodeRon Yorston8-7/+1297
Now that a binary with a UTF-8 manifest can run on Windows XP it's possible to configure a build which supports Unicode on Windows 10+ but which still runs on legacy systems. - Add the config file mingw32w_defconfig. This is a 32-bit build with the UTF-8 manifest which also runs on legacy systems. - A new config option, FEATURE_FAIL_IF_UTF8_MANIFEST_UNSUPPORTED, allows the check for legacy systems to be skipped. - An incompatibility with Windows XP in writeCon_utf8() has been fixed. See this GitHub issue for details: https://github.com/skeeto/w64devkit/issues/315
2025-12-01win32: update UTF-8 manifestRon Yorston1-5/+5
It seems that the UTF-8 manifest can be adjusted to avoid binaries failing to run on Windows XP. Make the necessary adjustment. This doesn't affect the legacy builds, only those with Unicode enabled. Nor does it change the code which prevents Unicode builds from running on platforms that don't support the manifest. See this GitHub issue for details: https://github.com/skeeto/w64devkit/issues/315
2025-11-28make: fix expansion of immediate-mode macrosRon Yorston2-1/+23
Immediate-mode macros shouldn't be recursively expanded, but are subject to suffix and pattern substitution. Adds 16 bytes to the 32-bit build. (pdpmake GitHub issue 77)
2025-11-26win32: avoid failure when localtime() argument is out of rangeRon Yorston2-2/+20
The implementation of localtime(3) in the Microsoft Windows runtime only accepts arguments between the Unix epoch (1970) and either 2038 or 3000 for 32-bit or 64-bit systems respectively. For values outside those limits it returns a NULL pointer. Unfortunately, upstream BusyBox hardly ever bothers to check the return value. Thus, when a call to stat(2) returned an all-zero FILETIME for a file, the 'stat' applet failed. An all-zero FILETIME represents a date in 1600, which is clearly before the Unix epoch. Add a wrapper to localtime(3) which detects an out-of-range value and returns a valid 'struct tm' for the Unix epoch. This is easier than adding checks on the return value of every call to localtime(3). Adds 32-48 bytes. (GitHub issue #548)
2025-11-23ash: allow ctrl-c to interrupt read in minttyRon Yorston1-19/+20
The command 'read -t 10' couldn't be interrupted by ctrl-c when ash was running in the mintty terminal emulator. This issue was introduced by commits 8e6991733 and b2901ce8e which fixed other problems with the 'read' builtin. Rearrange the code to avoid calling poll(2) in an interactive shell on Windows. (GitHub issue #547)
2025-11-22mkdir: correctly report directory creationRon Yorston1-2/+1
It was found that 'mkdir -p --verbose C:/' incorrectly reported that 'C:/' was created. Commit 0e0b5e9ff8 (mingw.c: ignore EACCES from mkdir if directory exists) fixed a failure to create directories but caused the `mkdir` applet to issue the wrong diagnostic. The underlying problem is in the Windows runtime implementation of _mkdir(): it can return the wrong errno in some cases, EACCES instead of EEXIST. Having the mkdir(2) wrapper return the correct errno should fix both the directory creation and verbose diagnostic problems. The website referenced in the previous commit is no longer available. archive.org has a copy: https://web.archive.org/web/20150224075238/http://www.apijunkie.com/APIJunkie/blog/post/2009/12/22/_mkdir-C-runtime-library-function-might-return-unexpected-error-values.aspx (GitHub issue #546)

When running `pgrep -x example` against a process `/bin/example --arg`, BusyBox fails to match, while GNU pgrep succeeds.

2025-10-05ash: allow ctrl-c to interrupt wait in presence of trapRon Yorston1-4/+21
Commit 387d01161 (ash: allow wait builtin to be interrupted) allowed the wait builtin to be interrupted by ctrl-c. However, this didn't work in the presence of a trap. When waitpid_child() detects an interrupt propagate this up the call stack so the wait builtin terminates and the trap is invoked. Adds 80-88 bytes. (GitHub issue #530)
2025-10-05ash: make ctrl-c trap handling closer to upstreamRon Yorston1-12/+10
Commit 64c8f5f3d0 (ash: add support for INT trap) didn't follow upstream behaviour. If a trap is supplied for SIGINT, upstream's signal handler detects this and doesn't call raise_interrupt(). The busybox-w32 implementation called raise_interrupt() but had it do nothing. Modify the code to match upstream's behaviour. Saves 16-36 bytes.
2025-10-03ash: allow wait builtin to be interruptedRon Yorston1-11/+12
After commit f6be217fa (ash: wait builtin should block) it wasn't possible to interrupt a call to wait with Ctrl-C. A blocking wait should be stopped from time to time to check for an interrupt. Adds 32 bytes. (GitHub issue #529)
2025-10-02ash: wait builtin should blockRon Yorston1-1/+1
It was found that the 'wait' shell builtin would use 100% of a core when waiting for a process to terminate: sleep 60 & wait This is a regression caused by commit bb8f6b688 (ash: fix slow running when background job is present). See the commit message and GitHub issue #434 for the long and involved history. The problem is in the Windows implementation of waitproc() in ash. The 'block' argument to waitproc() can take three values: DOWAIT_NONBLOCK DOWAIT_BLOCK DOWAIT_CHILD_OR_SIG The first two have obvious meanings. The third performs a non- blocking wait(2) and if no PID is returned it waits for SIGCHLD. So in effect it's a blocking wait. The Windows implementation would perform a non-blocking wait(2) but couldn't then wait for SIGCHLD, because Windows doesn't have such a signal. As a result the 'wait' builtin would loop calling waitproc(). To avoid this DOWAIT_CHILD_OR_SIG should be treated as a blocking wait in waitproc(). (GitHub issue #529)

Commit 6481bb22b (win32: use 64-bit time on 32-bit platforms) fails to build with mingw32-gcc prior to mingw-w64 10.0.0. Don't used 64-bit time for such builds. mingw-w64 7.0.0 and below don't have some definitions required for native TLS support. This is enabled by default in the 64-bit Unicode build.

Apply upstream commit 81274d8b3. On Windows it isn't necessary to reset the exception handler in evalbackcmd() or evalpipe(), as that will have been done by forkshell_init(). The globals_misc structure now contains a setjmp() buffer. On 64-bit Windows this needs 16-byte alignment. This is achieved in the forkshell data structure by placing the globals_misc data immediately after the 16-byte aligned forkshell data. Saves 144 bytes in the 64-bit build.
