* | win32: add a function to detect running with elevated privilegesRon Yorston2019-03-091-0/+3
| | | | | | | | | | Add is_admin() and use it to alter the command prompt in the line editor when running with admin privileges.
* | libbb: copy entire match during tab-completionRon Yorston2019-03-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Because tab-completion is case-insensitive the matching text might differ from what the user typed. Insert the whole of the matching text, not just the tail. Thus: $ cd doc<TAB> now expands to: $ cd Documents/
* | win32: stat(2) succeeds if fetching extra metadata failsRon Yorston2019-02-192-2/+8
| | | | | | | | | | | | | | | | | | Some files can't be opened to fetch additional metadata. When that happens allow stat(2) to successfully return what data it has. In a few cases where the inode number is used to determine if files are identical ignore invalid inode numbers.
* | win32: fix POSIX buildRon Yorston2019-02-171-0/+8
| | | | | | | | | | | | There were a few places where changes intended for the WIN32 build also affected the POSIX build. Fix these so the result of 'make defconfig; make' for busybox-w32 is identical to upstream BusyBox.
* | win32: make stat(2) fetch additional metadataRon Yorston2019-02-162-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the WIN32 implementation of stat(2) to fetch inode number, device id and number of hardlinks. This requires opening a handle to the target file so it will be slower. A number of features can be enabled or start to work: - tar can detect if an archive is being stored in itself; - find can support the -inum and -links options; - ls can display inode numbers; - diff can detect attempts to compare a file with itself; - du has better support for hardlinked files; - cp can detect attempts to copy a file over itself.

| * lineedit: fix SEGV in isk, hexedit, ed, closes 11661Denys Vlasenko2019-02-041-4/+5
| | | | | | | | | | | | | | | | | | | | | | fdisk, hexedit and ed calls read_line_edit in libbb/lineedit.c with NULL as first argument. On line 2373 of lineedit.c of busybox version 1.29.3, state->hist_file is referenced without checking the state->flag. This causes segmentation fault on fdisk, hexedit and ed on ARM Cortex-A9. It somehow works on x86_64. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | Commit 3476fb9f4 added a fake prefix to the applet pathname to identify the argument containing the name of an interpreted script. Skip over the prefix to prevent it appearing in error messages.
* | win32: add support for the euro currency symbolRon Yorston2019-02-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The euro currency symbol was added to some OEM code pages. See: https://www.aivosto.com/articles/charsets-codepages-dos.html Add a configuration option (enabled by default) to support this. When enabled: - The read_key() function requests wide character key events. This allows the euro symbol to be entered regardless of the console OEM code page, though it needs to be available in the ANSI code page. - Conversions between OEM and ANSI code pages in winansi.c are modified to work around a bug in the Microsoft routines. - If the OEM code page is 850 when BusyBox starts it's changed to 858. This is the only currently supported OEM code page. Also, the shell read builtin is modified to use read_key() whenever input is being taken from the console.

* | ps: display interpreted script name in comm columnRon Yorston2019-01-081-1/+17
| | | | | | | | | | | | | | | | | | | | | | When an interpreted script is being run the comm column in ps should display the name of the script not the name of the interpreter. Use a fake applet pathname to indicate which argument contains the script. This also allows pidof to obtain the pid of a script.
* | ps: add support for the args columnRon Yorston2019-01-081-11/+18
| | | | | | | | | | | | | | | | | | Implement read_cmdline() for WIN32 by storing the command line in the same way as the applet name. The applet name is actually used for the comm column which is truncated to COMM_LEN. Using this as the size of the bb_comm array avoids the need to calculate MAX_APPLET_NAME_LEN.
* | win32: implement umask(2)Ron Yorston2019-01-071-0/+9
| | | | | | | | | | | | | | | | | | umask() in the Microsoft C runtime takes different arguments to umask(2). Implement a fake umask(2) that remembers the mask and calls the Microsoft umask() with an appropriate value. Since the mask won't be inherited by children use an environment variable to pass any value set by the shell built-in umask.
* | iconv: import from win-iconvRon Yorston2019-01-061-1/+1
| | | | | | | | | | Source imported from https://github.com/win-iconv/win-iconv and modified to build in busybox-w32.
* | busybox: add --uninstall optionRon Yorston2019-01-051-2/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an option to allow hard links to be removed. busybox --uninstall file removes all hard links to the given file (including the file itself.) Since Microsoft Windows refuses to delete a running executable a BusyBox binary is unable to remove links to itself. busybox --uninstall -n file displays the names of all hard links to the given file. Although this feature is couched in terms of uninstalling BusyBox it's actually quite general: it can be used to delete or display hard links to any file.

* | win32: special treatment for PATHRon Yorston2018-12-142-21/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PATH shell variable is a special case. It can be exported to the environment where it might be interpreted by native applications which assume the separator is ';'. Hence: - require that the separator used in PATH is ';' - enforce this by intercepting calls to setvareq() that set PATH and adjusting its value if necessary. As a result of this the code to parse PATH can be simplified by replacing the hardcoded Unix ':' path separator by the platform- dependent macro PATH_SEP. The MANPATH variable is also required to use ';' as its separator but since it's less likely to be used this isn't enforced.
* | ash: move code from setup_environment()Ron Yorston2018-12-142-12/+1
| | | | | | | | | | | | | | ash calls setup_environment() but only uses a small amount of its functionality. Moving the code into ash itself means we don't need to customise setup_environment() for WIN32 and can remove it from the build.
* | win32: emulate SIGPIPERon Yorston2018-12-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code to check whether a write error is due to a broken pipe can now either: - return with error EPIPE; - cause the process to exit with code 128+SIGPIPE. The default is the latter but the behaviour can be changed by issuing signal(SIGPIPE, SIG_IGN) and signal(SIGPIPE, SIG_DFL) calls. No actual signal is involved so kill can't send SIGPIPE and handlers other than SIG_IGN and SIG_DFL aren't supported. This does, however, avoid unsightly 'broken pipe' errors from commands like the example in GitHub issue #99: dd if=/dev/urandom | tr -dc _A-Z-a-z-0-9 | head -c${1:-32};echo;

| |
* | lineedit: improvements to tab completionRon Yorston2018-12-082-10/+22
| | | | | | | | | | | | | | | | | | | | Since getpwent isn't implemented for WIN32 there's no point in enabling FEATURE_USERNAME_COMPLETION. Use case-insensitive comparisons when matching filenames. The code to exclude non-executables when tab completing executables is WIN32-specific and shouldn't omit directories.
* | win32: rework adding of extensions to filenamesRon Yorston2018-12-061-21/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously there was one function to handle adding extensions to executable filenames, add_win32_extension(). Refactor this into three functions: add_win32_extension() appends the suffix to the argument string in-place. The argument must be long enough to cope with this, as is the case in ash where path_advance() adds 4 bytes to each filename for just this reason. alloc_win32_extension() is equivalent to the old add_win32_extension(). It allocates a string to hold the new filename then calls the new add_win32_extension() function. The caller is responsible for managing the returned string. auto_win32_extension() calls alloc_win32_extension() and saves the resulting string using auto_string(). It's used where the new filename is consumed immediately or the actual value isn't needed. Rewrite code to use the most appropriate function. Also reorder some code in find_executable() and find_command().

Two types can be distinguished: custom scripts and scripts implementing applets. Custom scripts should be placed in the 'embed' directory at build time. They are given a default applet configuration and appear as applets to the user but no further configuration is possible. Applet scripts are integrated with the BusyBox build system and are intended to be used to ship standard applets that just happen to be implemented as scripts. They can be configured at build time and appear just like native applets. Such scripts should be placed in the 'applets_sh' directory. A stub C program should be written to provide the usual applet configuration details and placed in a suitable subsystem directory. It may be helpful to have a configuration option to enable any dependencies the script requires: see the 'nologin' applet for an example. function old new delta scripted_main - 41 +41 applet_names 2773 2781 +8 applet_main 1600 1604 +4 i2cdetect_main 672 674 +2 applet_suid 100 101 +1 applet_install_loc 200 201 +1 applet_flags 100 101 +1 packed_usage 33180 33179 -1 tryexec 159 152 -7 evalcommand 1661 1653 -8 script_names 9 - -9 packed_scripts 123 114 -9 complete_cmd_dir_file 826 811 -15 shellexec 271 254 -17 find_command 1007 990 -17 busybox_main 642 624 -18 run_applet_and_exit 100 78 -22 find_script_by_name 51 - -51 ------------------------------------------------------------------------------ (add/remove: 1/2 grow/shrink: 6/9 up/down: 58/-174) Total: -116 bytes text data bss dec hex filename 950034 477 7296 957807 e9d6f busybox_old 949918 477 7296 957691 e9cfb busybox_unstripped Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
