* | ash: code shrinkRon Yorston2021-02-141-1/+0
| | | | | | | | | | Since there's only one call to mingw_spawn_forkshell() we might as well just call spawnve() directly from ash.
* | win32: implement symlink(2)Ron Yorston2021-02-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide an implementation of symlink(2). Calls to symlink(2) will fail in default Windows installations unless running with elevated privileges. Failure to create a symlink when extracting files from an archive is therefore treated as a non-fatal error. There are two ways to permit the creation of symlinks: - Edit security policy to give users the 'Create symbolic links' privilege. Unfortunately this doesn't work for users who are an Administrator. - Enable developer mode, which is available in later versions of Windows 10. The ability to create symlinks is not available in Windows XP or ReactOS.
* | win32: make readlink(2) implementation unconditionalRon Yorston2021-02-121-4/+0
| | | | | | | | | | | | | | There doesn't seem to be much advantage in having readlink(2) as a configuration option. Making it unconditional reduces divergence from upstream and allows the removal of a check for ENOSYS that's been in busybox-w32 since the start.

* | tls: avoid unnecessary changes to POSIX build, part 2Ron Yorston2021-01-252-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On reflection, the previous commit may have been ill-advised. There are many calls to open_read_close() and most shouldn't be able to access special devices. (Though in practice only a few are enabled in busybox-w32.) Nonetheless, I've implemented a new mechanism which uses the macro MINGW_SPECIAL() to mark calls to functions that are allowed to access special devices. An unrelated change is to avoid compiling fputs_stdout() in coreutils/printf.c for the POSIX build.
* | libarchive: allow extraction of hard linksRon Yorston2021-01-191-7/+0
| | | | | | | | | | | | | | | | Allow create_or_remember_link() to create hardlinks. As a result tar and cpio can now extract hard links. Since unzip only supports symlinks it sees no improvement. As before, attempts to extract symlinks result in a warning.

* | win32: use built-in applets for non-existent binaries with Unix-style pathsRon Yorston2020-08-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | win32: handle Unix-style absolute paths for executablesRon Yorston2020-08-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | win32: use a static buffer in get_system_drive()Ron Yorston2020-08-131-1/+1

* | win32: code shrinkRon Yorston2020-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | 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.
* | win32: move code to fork (de)compressor to a functionRon Yorston2020-08-051-0/+1
