* | win32: improved support for c:path path namesRon Yorston2019-03-304-29/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Microsoft Windows permits path names of the form 'c:path', without a path separator after the colon. The system records a current directory for each drive and the path is interpreted relative to that. Since Windows API calls understand 'c:path' path names many commands in busybox-w32 already work with them. This commit adds the following: - The 'cd' shell built-in interprets 'c:path' path names correctly. Previously it treated them as relative to the shell's concept of the current working directory, not the current directory of the specified drive. - The 'pwd' shell built-in takes the '-a' option to list the current directory for all drives. - 'c:path' path names are subject to tab-completion. Paths of the form 'c:path' don't work for mapped network drives or paths that have been associated with a drive using SUBST. See GitHub issue #147.
* | win32: update implementation of setmntent(3)Ron Yorston2019-03-302-4/+7
| | | | | | | | | | | | | | - The arguments to setmntent(3) are unused: add a macro to drop them at call sites. - Allow remote drives.
* | win32: interpret absolute paths as relative to %SYSTEMDRIVE%Ron Yorston2019-03-286-1/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BusyBox contains hardcoded references to absolute paths which are unique in the *nix world but on Microsoft Windows are interpreted as being on the current drive. To make these unique again consider them to be relative to %SYSTEMDRIVE%. Support this by adding functions to: - determine the system drive (not using the environment variable); - change a process's current directory to the root of the system drive; - make relative paths absolute before changing directory (if needed). The following applications have been modified: - ash references /etc/profile from the system drive; - dpkg places its data store on and installs files to the system drive; - rpm installs files to the system drive; - man looks for configuration files and man pages on the system drive. See GitHub issue #158.
* | man: proper handling of default path and config fileRon Yorston2019-03-282-0/+8
| | | | | | | | | | | | | | | | Don't overwrite the default path when the path relative to the executable is added. Remove trailing carriage returns when parsing the configuration file.
* | man: don't skip default path which appears in config fileRon Yorston2019-03-281-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the MANPATH environment variable isn't set a provisional default path of /usr/man is placed in man_path_list. This is only used if a configuration file doesn't contain an alternative path. If a configuration file lists the default path first: MANPATH /usr/man:/usr/share/man add_MANPATH() sees that the default entry is already present and skips it. As a result man_path_list only contains the second and subsequent components of the configured MANPATH. In such cases the path should not be skipped.
* | win32: share code to find root prefix of pathRon Yorston2019-03-234-51/+42
| | | | | | | | | | | | | | Move unc_root_len() from ash to mingw32.c and use it in the new function root_len(), which can be used in make_directory(). This reduces changes to upstream code and saves a few bytes.
* | win32: improve filesystem detection and displayRon Yorston2019-03-206-11/+23
| | | | | | | | | | | | | | | | | | | | Miscellaneous improvements: - Enable '-a' option to display all filesystems in df(1). - Detect the UDF CDROM filesystem and display it in 'stat -f'. - Let getmntent(3) handle CDROM and floppy devices, ignoring those that have no media. - Set number of inodes and filesystem flags to 0 in statfs(2).
* | win32: change stat(2) error code in certain casesRon Yorston2019-03-201-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 325fee1f9 (win32: change handling of trailing slashes in stat(2)) caused stat(2) to return EINVAL in some cases when ENOENT might have been more appropriate. This caused the command: rm -f dir/* to report an error when the directory was empty, contrary to its expected behaviour of saying nothing. Fixes GitHub issue #155.

* | vi: fix spurious error on opening file with CRLF line endingsRon Yorston2019-03-171-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 91e49fbc7 (vi: add a function to count CRs in the text buffer) resulted in the spurious error "can't read 'file'" when opening a file with CRLF line endings. This was because the count function was called with an incorrect pointer into the text buffer. The upstream code: p = text_hole_delete(p + cnt, p + size - 1, NO_UNDO); unnecessarily updates the pointer p: it's never used again.

* | ash: enforce ';' separator in CDPATH and MANPATH variablesRon Yorston2019-03-161-11/+23
| | | | | | | | | | | | | | | | | | | | Commit a23624237 (win32: special treatment for PATH) required the PATH variable to use ';' as the separator between components and enforced this by intercepting attempts to update it. Do the same for the CDPATH and MANPATH variables. Also, fix a case in cdcmd() where the wrong separator was used.
* | ash: set current working directory on startupRon Yorston2019-03-151-0/+7
| | | | | | | | | | | | | | | | | | | | | | When the shell starts behave as though the user had manually changed to the current working directory of the process, but only if it's an interactive, non-login shell and the '-d' flag isn't present. This gives more consistent behaviour when the shell is started in a drive mapped to a network share or a symlinked directory. This completes the changes requested in GitHub issue #148.
* | win32: add function to convert slashes to backslashesRon Yorston2019-03-159-25/+29
| | | | | | | | | | | | | | | | | | There are now two places where slashes are converted to backslashes throughout a string so it makes sense to create a function to do this. To avoid confusion rename convert_slashes() to bs_to_slash() and call the new function slash_to_bs().
* | lineedit: add a command to change backslashes to slashesRon Yorston2019-03-152-6/+7
| | | | | | | | | | | | | | | | | | | | | | When a path name is copied to a console application using drag and drop the path separator is backslash. To handle this situation in the shell add an editing command (Ctrl-Z) to convert all backslashes on the current line to slashes. See GitHub issue #149. Also remove some unused code from read_key().
* | win32: realpath(3): remove trailing slashRon Yorston2019-03-141-1/+4
| | | | | | | | | | | | | | | | | | If the path is that of a drive mapped to a network share _fullpath() leaves the trailing slash on the drive name and it remains present after the call to resolve_symlinks(). Remove a trailing slash from the resolved path unless it's preceded by a colon.
* | su: canonicalise directory before elevating privilegesRon Yorston2019-03-141-5/+11
| | | | | | | | | | | | If the current directory is in a drive mapped to a network share we may not be able to access it once we have elevated privileges. Avoid this by canonicalising the path before calling ShellExecuteEx().

| * udhcpc: don't exit after backgrounding on -n -bAndrey Mazo2019-02-272-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, running "udhcpc -n -b" causes udhcpc to go to background and then exit after some time unless a lease is obtained. It's not very useful to do so as the calling process doesn't know if the lease was obtained or not anyway. The code actually tries to favor "-b" over "-n", but doesn't clear "-n" flag while clearing "-b" after backgrounding. So, clear "-n" flag after going into background. This effectively makes "-b" override "-n" completely and "-n -b" behave the same as "-b". This allows to override default "-n" option, passed to udhcpc by ifupdown, without recompiling busybox.

This has been fixed in dash by commit 2bc6caa. The maintainer writes: I have simplified evaltree so that it simply sets the stack mark unconditionally.

With these changes the shell started by 'su' is a lot more like a *nix root shell.
