* nc: switch to using poll(2)Ron Yorston2023-03-031-49/+2
| | | | | | | | | | | | Upstream started using poll(2) rather than select(2) in `nc` some time ago, in commit 5b3b468ec (nc: use poll() instead of select()). Now that poll(2) in busybox-w32 has been updated to work with `nc` switch to using the same code as upstream. As a result of this change nothing in busybox-w32 now uses the select(2) implementation. This reduces the size of the binaries by about 3.4KB.

* | nc: alter conditional compilationRon Yorston2021-01-241-7/+55
| | | | | | | | | | | | | | | | | | | | Change conditional compilation to use PLATFORM_MINGW32 instead of NC_EXTRA. Enabling NC_EXTRA won't work for busybox-w32, but then it didn't before. Also, instead of just reverting upstream commit 5b3b468ec (nc: use poll() instead of select()) include both old and new code, keyed on PLATFORM_MINGW32.

| * libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne2019-07-021-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower overhead call to bb_perror_msg() when only a string was being printed with no parameters. This saves space for some CPU architectures because it avoids the overhead of a call to a variadic function. However there has never been a simple version of bb_error_msg(), and since 2007 many new calls to bb_perror_msg() have been added that only take a single parameter and so could have been using bb_simple_perror_message(). This changeset introduces 'simple' versions of bb_info_msg(), bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and bb_herror_msg_and_die(), and replaces all calls that only take a single parameter, or use something like ("%s", arg), with calls to the corresponding 'simple' version. Since it is likely that single parameter calls to the variadic functions may be accidentally reintroduced in the future a new debugging config option WARN_SIMPLE_MSG has been introduced. This uses some macro magic which will cause any such calls to generate a warning, but this is turned off by default to avoid use of the unpleasant macros in normal circumstances. This is a large changeset due to the number of calls that have been replaced. The only files that contain changes other than simple substitution of function calls are libbb.h, libbb/herror_msg.c, libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c, networking/udhcp/common.h and util-linux/mdev.c additonal macros have been added for logging so that single parameter and multiple parameter logging variants exist. The amount of space saved varies considerably by architecture, and was found to be as follows (for 'defconfig' using GCC 7.4): Arm: -92 bytes MIPS: -52 bytes PPC: -1836 bytes x86_64: -938 bytes Note that for the MIPS architecture only an exception had to be made disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h) because it made these files larger on MIPS.

* | Remove fake signal-handling codeRon Yorston2018-03-011-0/+4
| | | | | | | | | | | | | | | | | | Microsoft Windows has only limited support for signals. busybox-w32 initially papered over this fact by adding definitions for unsupported signals and signal-handling functions. Remove this fake code and deal with the consequences by excluding anything that fails to compile as a result.

* | win32: make vfork fail at compile-timeRon Yorston2017-08-301-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | Nothing in busybox-w32 uses fork. Remove the implementations of fork, vfork and xvfork so that, for example, enabling cpio pass-through causes an error at compile-time, not run-time. MinGW-w64 defines pid_t, so we don't have to. Ensure code containing xvfork in netcat is disabled when NC_EXTRA is disabled. Otherwise removing the implementation of vfork costs 64 bytes.
