| * ash: expand: Fix bugs with words connected to the right of $@Denys Vlasenko2018-04-025-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream email: This is actually composed of two bugs. First of all our tracking of quotemark is wrong so anything after "$@" becomes quoted. Once we fix that then the problem is that the first space character after "$@" is not recognised as an IFS.

Upstream patch: From: Herbert Xu <herbert@gondor.apana.org.au> Date: Fri, 9 Mar 2018 00:14:02 +0800 parser: Add syntax stack for recursive parsing Without a stack of syntaxes we cannot correctly these two cases together: "${a#'$$'}" "${a#"${b-'$$'}"}" A recursive parser also helps in some other corner cases such as nested arithmetic expansion with paratheses. This patch adds a syntax stack allocated from the stack using alloca. As a side-effect this allows us to remove the naked backslashes for patterns within double-quotes, which means that EXP_QPAT also has to go. This patch also fixes removes any backslashes that precede right braces when they are present within a parameter expansion context, and backslashes that precede double quotes within inner double quotes inside a parameter expansion in a here-document context. The idea of a recursive parser is based on a patch by Harald van Dijk.

* | libarchive: failure to extract symlink isn't fatalRon Yorston2018-04-092-1/+13
| | | | | | | | | | | | | | | | Recent upstream changes made the failure of symlink(2) when extracting from an archive a fatal error. The busybox-w32 implementation of symlink(2) always fails. Just issue a warning and move on.
* | win32: more backslash to slash conversionsRon Yorston2018-04-082-1/+5
| | | | | | | | | | | | | | | | | | Convert backslashes to slashes: - in the main program's argv[0] - in the shell's file argument Also, fix the code to remove the .exe extension from argv[0] in the main program.

* | win32: don't leak pipe data structuresRon Yorston2018-04-071-58/+66
| | | | | | | | | | | | | | | | | | | | | | | | popen uses an array of pipe_data structures to record information that's later used by pclose. pclose releases the structure after use. The lower-level pipe function mingw_popen_fd was also using this array of structures but didn't provide any way to release them. Avoid this leak by letting mingw_popen_fd use a local structure instead.

* | win32: exclude termios codeRon Yorston2018-04-056-21/+26
| | | | | | | | | | The code to manipulate terminal settings serves no purpose in WIN32. Use conditional compilation to exclude much of it.

* | ash: emulate raw input to read builtinRon Yorston2018-04-051-2/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | Use read_key to emulate raw input when reading from the console. Limit this to cases where raw input is necessary: - a maximum number of characters is to be read (-n) - a timeout has been specified (-t) - a non-standard delimiter is in use (-d) This should fix GitHub issue #112 (and other things too!). Also, omit sections of code that serve no purpose on WIN32.
* | win32: ensure timeout works in read_keyRon Yorston2018-04-051-4/+4
| | | | | | | | | | | | Move the wait for timeout into the while loop of read_key. Otherwise the timeout won't be checked after any event that doesn't result in a value being returned.
* | ps: obtain applet names from other BusyBox processesRon Yorston2018-04-046-42/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the code which passed applet names to child processes using environment variables. This only allowed ps to display names for its ancestors. Instead attempt to read applet names from the memory of unrelated processes. The Microsoft documentation alone wasn't enough to figure out how to do this. Additional hints from: https://stackoverflow.com/questions/4298331/exe-or-dll-image-base-address https://stackoverflow.com/questions/14467229/get-base-address-of-process
* | fsync: avoid a gratuitous difference from upstreamRon Yorston2018-04-032-3/+1
| | | | | | | | | | Move the definition of O_NOCTTY to mingw.h so that fsync.c is the same as upstream.
* | ttysize: enable in default configurationRon Yorston2018-04-032-2/+2
| | | | | | | | | | | | | | | | | | | | Previously $ HEIGHT=$(ttysize h) would always return a default height of 24 because stdout wasn't connected to a console. Now that get_terminal_width_height also checks stderr the above works.
* | win32: improvements to get_terminal_width_heightRon Yorston2018-04-034-20/+25
| | | | | | | | | | | | | | | | - move winansi_get_terminal_width_height from winansi.c to ioctl.c, the only caller; - check both stdout and stderr for a connection to a console; - omit unnecessary code in get_terminal_width_height (because the WIN32 implementation ignores the file descriptor).
* | win32: simplify isatty replacementRon Yorston2018-04-031-5/+1
| | | | | | | | | | Don't treat input and output file descriptors differently: if we aren't connected to a console GetConsoleMode will fail for either.
* | ash: reinstate applet name variable after forkshellRon Yorston2018-04-033-6/+16
| | | | | | | | | | | | When 'sh --forkshell' is invoked the BB_APPLET_<pid> environment variable is set, but then it's cleared when the environment of the child process is restored. Reinstate it in reinitvar.
* | ash: minor forkshell fixesRon Yorston2018-04-021-7/+5
| | | | | | | | | | | | | | | | - update forkshell_evalbackcmd to match the non-MinGW code; - increase the size of the buffer to hold the forkshell handle for 64-bit machines; - use memcpy to copy the globals_var structure to avoid copying bits by hand.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Part of upstream commit: Date: Thu Mar 8 08:37:11 2018 +0100 Author: Harald van Dijk <harald@gigawatt.nl> parser: use pgetc_eatbnl() in more places dash has a pgetc_eatbnl function in parser.c which skips any backslash-newline combinations. It's not used everywhere it could be. There is also some duplicated backslash-newline handling elsewhere in parser.c. Replace most of the calls to pgetc() with calls to pgetc_eatbnl() and remove the duplicated backslash-newline handling. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Not adding "readtoken1(pgetc_eatbnl(), DQSYNTAX..." changes, since readtoken1() handles the "starts with backslash + newline" case itself.
