* | win32: stat(2) succeeds if fetching extra metadata failsRon Yorston2019-02-191-3/+5
| | | | | | | | | | | | | | | | | | 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: make stat(2) fetch additional metadataRon Yorston2019-02-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | libarchive: remove more symlink codeRon Yorston2019-02-142-4/+6
| | | | | | | | | | | | | | Since symlinks aren't supported in busybox-w32 remove more of the code that handles them. Saves 64 bytes.

* | tar: return correct exit code for empty tar fileRon Yorston2019-01-061-5/+0
| | | | | | | | | | The WIN32 implementation of check_errors_in_children shouldn't have reset bb_got_signal as it's used to signal an error.
* | win32: emulate SIGPIPERon Yorston2018-12-111-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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;

| * hush: allow hush to run embedded scriptsRon Yorston2018-11-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Embedded scripts require a shell to be present in the BusyBox binary. Allow either ash or hush to be used for this purpose. If both are enabled ash takes precedence. The size of the binary is unchanged in the default configuration: both ash and hush are present but support for embedded scripts isn't compiled into hush.

| * ash: allow shell scripts to be embedded in the binaryDenys Vlasenko2018-11-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To assist in the deployment of shell scripts it may be convenient to embed them in the BusyBox binary. 'Embed scripts in the binary' takes any files in the directory 'embed', concatenates them with null separators, compresses them and embeds them in the binary. When scripts are embedded in the binary, scripts can be run as 'busybox SCRIPT [ARGS]' or by usual (sym)link mechanism. embed/nologin is provided as an example. function old new delta packed_scripts - 123 +123 unpack_scripts - 87 +87 ash_main 1103 1171 +68 run_applet_and_exit 78 128 +50 get_script_content - 32 +32 script_names - 10 +10 expmeta 663 659 -4 ------------------------------------------------------------------------------ (add/remove: 4/0 grow/shrink: 2/1 up/down: 370/-4) Total: 366 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
