* | winansi: code shrinkRon Yorston2020-01-081-37/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rework the ANSI emulation code to reduce its size. - Fetch console attributes when required rather than caching them. The init() function is no longer required; the only remaining initialisation is now performed in is_console(). - Turning off inverse video (ESC[27m) didn't work properly. This has been improved though it still doesn't work in some unlikely cases (ESC[7;27m). These changes save 180 bytes.

* | winansi: restore correct attributes after lsRon Yorston2020-01-071-1/+7
| | | | | | | | | | | | | | | | | | As reported in GitHub issue #178 the last colour set by the ls command is retained in the console. This is due to the previous commit reinitialising the stored attributes more frequently than it should. Attriubutes should only be initialised once.
* | winansi: fix escape processing in Windows 10 release 1809Ron Yorston2020-01-061-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported in GitHub issue #177, ANSI escape sequences don't work reliably after shell redirection. The problem appears to be due to a change in the behaviour of dup2() in Windows 10 release 1809. The escape handling code kept a copy of the console handle for internal use. Prior to Windows 10 release 1809 this worked; since then unwinding shell redirections results in the actual console handle changing from time to time for reasons that are unknowable without access to the source code. Fix this by always fetching the console handle instead of caching it.
* | ash: copy line editing history during forkshellRon Yorston2019-12-161-10/+94
| | | | | | | | | | Add code to store line editing history in the forkshell data block. This allows things like 'history | grep whatever' to work.
* | ash: copy alias table during forkshellRon Yorston2019-12-151-1/+77
| | | | | | | | | | | | | | | | The alias table has never been copied during forkshell. As a result any attempts to use the alias command in conjunction with pipes or backquote expansion, for example, fail. Fix this by adding the necessary code.

* | ash: revert change to behaviour of -s optionRon Yorston2019-08-161-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Upstream BusyBox commit f3634584d (ash,hush: show 'c' in $- if run in "sh -c CMD") changed the behaviour of -s to match that of bash rather than dash. This means that the -s and -c options can't be combined. This combination of options is used by the Windows 'su' applet to prevent the new console window from shutting down after the command has run. It's also useful when the shell is to be run with an initialisation command (GitHub issue #100). Revert the change so -s behaves as in dash.

| * libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne2019-07-02225-736/+845
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
