2020-08-19ls: allow backslashes to be replaced in displayed pathsfix_backslashRon Yorston1-0/+15
Normally 'ls' displays paths exactly as the user enters them: $ ls .//file .//file In busybox-w32 paths using backslash as a separator are displayed in a form that can't be reused as input to the shell: $ ls .\\file .\file Allow backslashes to be replaced with forward slashes if the environment variable BB_FIX_BACKSLASH is set to 1. See GitHub issue #196.
2020-08-15busybox: create custom installation directoryRon Yorston1-5/+6
If a custom installation directory is specified try to create it. Don't worry if we can't, we'll find out when the links fail.
2020-08-14busybox: add option to install to Unix-style pathsRon Yorston2-12/+35
The command 'busybox --install -u' installs links to Unix-style paths in the system drive.
2020-08-13win32: use built-in applets for non-existent binaries with Unix-style pathsRon Yorston5-11/+83
Shell scripts moved from Unix may contain hard-coded paths to binaries such as /bin/sh. A recent commit made it possible to execute such binaries reliably, but that does require them to be installed. As an alternative solution: if a binary with a standard Unix path prefix can't be found but is available as a built-in applet, run the applet. Add the function unix_path() to detect paths starting with /bin, /usr/bin, /sbin or /usr/sbin. Use this function in: - the 'which' applet - shellexec(), describe_command() and find_command() in ash - mingw_spawn_1() See GitHub issue #195.
2020-08-13httpd: code shrinkRon Yorston1-3/+2
Use the new need_system_drive() function in httpd. Saves 16 bytes.
2020-08-13win32: handle Unix-style absolute paths for executablesRon Yorston7-4/+68
As noted in commit 548ec7045 (win32: interpret absolute paths as relative to %SYSTEMDRIVE%) a path starting with a '/' in the Unix world is treated as relative to the current drive by Windows. To avoid ambiguity that commit considered certain such paths to be relative to %SYSTEMDRIVE%. Extend this to paths representing executables. Add the functions need_system_drive() and auto_add_system_drive() to detect the need for a system drive prefix and to add it if necessary. Use these functions in: - the 'which' applet - the find_executable() function - tab-completion code - PATH look-up, shellexec(), describe_command() and find_command() in ash - parse_interpreter() and mingw_spawn_1() With these changes executable paths starting with a slash are handled consistently, whatever the current drive.
2020-08-13win32: use a static buffer in get_system_drive()Ron Yorston4-18/+16
Allocate static storage for the system drive string instead of making a new allocation on every call. This is easier to manage. Adds 16 bytes.
2020-08-13win32: code shrinkRon Yorston5-7/+17
Add a new function, has_path(), to detect that an executable name doesn't require a path look-up. Also, since is_absolute_path() is now only used in shell/ash.c move its definition there from include/mingw.h. Saves 128 bytes.
2020-08-13which: handle paths of form 'c:path'Ron Yorston1-2/+5
Add another case where paths of the form 'c:path' need special treatment. Adds 16 bytes.
2020-08-05win32: move code to fork (de)compressor to a functionRon Yorston4-38/+29
Use a new common function, mingw_fork_compressor(), to implement fork_transformer() in open_transformer.c and vfork_compressor() in tar.c. Saves 160 bytes.
2020-08-04which: rearrange conditional compilationRon Yorston1-1/+6
The code for standalone shell mode should only be built for WIN32.
2020-08-03win32: update strptime(3) implementationRon Yorston1-12/+19
Update to latest code from gnulib. This adds a '%q' (quarter) field descriptor. Remove the 'neg' variable from the code to handle the '%z' (timezone) field descriptor. Since our struct tm lacks a tm_gmtoff member '%z' is only supported "for reasons of symmetry". Since the computed value is never used there's no need to negate it.
2020-08-03build system: reinstate PLATFORM_LINUXRon Yorston2-0/+2
Removing 'select PLATFORM_LINUX' from ps and stat has no material effect: it just causes match_fstype.o to be built needlessly. Remove this difference from upstream.
2020-08-03install: enable in default buildRon Yorston2-10/+14
Attempting to set file ownership and permissions may not work exactly as on *NIX.
2020-07-25win32: code shrink kill(2)Ron Yorston3-33/+19
- Drop exit_code argument from kill_SIGTERM_by_handle() - Pass signal number rather than exit code to other functions - Merge kill_SIGKILL() and kill_SIGTEST() Saves 112 bytes.

2020-07-19ts: correct output in 64-bit buildRon Yorston1-0/+8
ts failed to output the correct time when built for 64-bit Windows. In 64-bit builds time_t is a 64-bit quantity whereas the tv_sec member of struct timeval is 32-bit. https://sourceforge.net/p/mingw-w64/bugs/783/ Use a temporary time_t value in 64-bit builds.
2020-07-09win32: alter build flagsFRP-3532-g01a256149Ron Yorston1-1/+1
Add -fno-builtin-strndup to the build flags, otherwise builds with link-time optimisation can't find strndup.

2020-07-09ash: tidy code, no functional changeRon Yorston1-3/+2
2020-07-09chattr, lsattr: enable in the default configurationRon Yorston6-7/+138
The chattr and lsattr utilities allow file attributes to be changed and displayed. Modify them to support Windows file attributes using the same names as Cygwin. Only allow a limited subset of attributes to be changed: just most of those supported by SetFileAttributes(). Since it isn't possible to set all attributes the '=' operator isn't allowed.
2020-07-09ls: treat hidden files as if their names begin with a dotRon Yorston1-0/+12
On Unix 'ls' treats filenames starting with a dot as hidden and only displays them if the '-a' or '-A' option is given. Extend similar treatment to files with the Windows hidden flag.
2020-07-09win32: return raw file attributes in struct mingw_statRon Yorston2-0/+5
Until now the emulated stat(2) system calls have only returned a synthesised Unix-style mode value. Also return the raw Windows file attributes.
2020-07-07ash: fix shell optionsRon Yorston1-7/+7
The Windows-specific shell options winxp, noconsole and nocaseglob have had the wrong indices in optlist since the merge with upstream BusyBox in commit 517cf74f6.
2020-06-30ash: improve handling of UNC pathsRon Yorston2-38/+56
Be more strict about identifying UNC paths in unc_root_len(). In updatepwd() in ash: - Skip duplicate leading slashes unless the directory is a UNC path. - Rewrite detection and handling of the five possible types of path. This improves cases like 'cd ///' and 'cd /xyz' when the current directory is a UNC path. See GitHub issue #192.

2020-06-29ash: avoid duplicated slashes in output of type/command builtinsRon Yorston2-0/+10
Microsoft developers have a penchant for adding trailing slashes to entries in PATH: C:/Windows/System32/WindowsPowerShell/v1.0/ C:/Windows/System32/OpenSSH/ The 'type' and 'command -v' shell builtins return paths with duplicated slashes for executables in those directories. See GitHub issue #191. Bonus fixes: - handle backslashes as well as slashes in concat_path_file() - convert backslashes to slashes in the output of 'type', 'command -v'
