| | | | | | | | | | | | | | | | | | | | | | | | | | The rationale here is that unsetting HISTFILE in /etc/profile does not "stick": if it's unset, the default one is set later (after /etc/profile is executed) by the shell.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was observed that getty crashes on RISC-V 64-bit target, with the busybox binary compiled by clang/LLVM 17 with -O2. Not only getty, but also some other applets like syslogd/vi are broken too. Commit 5156b245 ("Make const ptr assign as function call in clang") introduced XZALLOC_CONST_PTR() to defeat the compiler optimization, however it only fixed a small number of broken places when compiling busybox with clang/LLVM. A large number of places remain broken. This commit treats ASSIGN_CONST_PTR() the same way as XZALLOC_CONST_PTR().

| | | | | | | | | | | | | | | | | | | | | | | | | | Add a new feature to libbb, FEATURE_USE_CNG_API, which enables the use of the Cryptography API: Next Generation library to calculate checksums. It is disabled by default except in the mingw64u default config, as the API requires Windows 10+ to function. Usage of this API provides a size benefit and delegates hardware optimizations to the operating system cryptography library. Based on GitHub PR #498 by rfl890. Saves 4064 bytes in the mingw64u case.
* | win32: enhanced support for SIGPIPEFRP-5579-g5749feb35Ron Yorston2025-02-081-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 68ddd4ec3c (win32: emulate SIGPIPE) allowed broken pipes to be detected so that processes could either return EPIPE or terminate. Later, commit 1b2ee3667 (win32: add fake HUP and QUIT signals) added support for two additional fake signals, thus allowing the 'kill' applet to refer to them by name and the shell to define (though not execute) traps for them. Add PIPE to the list of signals known to 'kill' and the shell, though still without support for calling the trap function. (GitHub issue #482)

| * libbb: tidy argument checks in getopt32()Ron Yorston2024-12-091-8/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When getopt32() has complementary options it's possible to specify the minimum and maximum number of arguments allowed. Checking these values was inconsistent: - '?' correctly checked that it was followed by a digit but set the otherwise unused spec_flgs variable on error. - '=' failed to check that it was followed by a digit. function old new delta vgetopt32 1307 1319 +12 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
