2020-12-16chmod.c: mask out the file type bits.Elliott Hughes
The kernel will do this for us on both Linux and macOS, but error messages are a bit misleading if we don't do it ourselves --- it can look as if the failure is because of the type bits.

2020-12-07sed: add 'x' flag to the 's' command.Elliott Hughes
The GNU tar manual, when talking about the `tar --transform` option that I need to implement, describes the 'x' flag by saying "regexp is an extended regular expression (see section 'Extended regular expressions' in GNU sed)". Only it turns out that even the latest GNU sed doesn't actually have that flag. It's unique to `tar --transform`. That link is just telling you that the sed manual will explain extended regular expressions, not that GNU sed also supports the 'x' flag. So I don't know whether we want this in toybox sed after all. (It made sense that sed would have such a flag, but no sed that I know of actually does.)
2020-12-06unicode: new toy.Elliott Hughes
Based loosely on the Plan9/Inferno utility, and a convenient way to go back and forth between code points and utf8 sequences. This patch also fixes a couple of bugs in wctoutf8 (and the tests for this toy effectively serve as unit tests for wctoutf8/utf8towc).
2020-12-06Remove CONFIG_TOYBOX_I18N and just always support utf8.Rob Landley

Add new toy `pwgen`. A usefule password generation utility.
2020-12-05tr: fix pathological flushing.Elliott Hughes
The AOSP build doesn't use tr (or anything that's still in pending), but the kernel folks have been more aggressive. They found that tr's pathological flushing was adding minutes to their build times. Just removing the fflush() made tr significantly faster for my trivial test, but still slow, with all the time going into stdio. Rewriting the loop to modify toybuf in place and then do one write per read made most of the difference, but special-casing the "neither -d nor -s" case made a measurable difference too on a Xeon.

Can't use the same set_terminal() logic as ptys because it not displaying data, it should just accurately copy it.

Use 0 optstr prefix, fix bug initializing toys.envc one too low.
2020-11-15date: add --iso and the %:z output format.Elliott Hughes
I didn't know until implementing this that --iso is actually called --iso-8601 and that GNU date will actually accept any prefix. --iso-8 works fine too. I've assumed that --iso (that I always used) and --iso-8601 (as given in the documentation) are the only two that matter.
2020-11-14Allow 0 prefix to optstr to include argv[0] in optargs[0].Rob Landley
2020-11-12readelf: harden against invalid input.Elliott Hughes
I also promised to fix readelf. Where in file(1) I made no attempt to say what was bad (or even to change `goto bad` to explicitly say that *anything* was bad), I believe that readelf is much more likely to be shown invalid ELF files, and that it would be useful to have some clue as to what's wrong. Relatedly, this patch removes all existing error_exit() calls in case it's being used on multiple files. Again, this survived ~24hrs of AFL++ trying to blow its house down. Test: ~/AFLplusplus/afl-fuzz -i tests/files/elf -o fuzz-out -- ./readelf -a @@
2020-11-12file: harden against invalid input.Elliott Hughes
I promised months ago I'd fix this, and there was a (not visible to the public but filed by a member of the public) bug filed against Android in the meantime, but judged No Security Impact because "toybox is not a security boundary". Anyway, it seemed high time I learned about fuzzing command-line tools with AFL++, so here we are. With these patches (and starting from the ELF files in test/files/elf), toybox file survived ~24hours against AFL++. Amusingly it corrupted the ELF files hard enough that it also managed to find a bug in the code for MS-DOS executables, which is the motivation for the final hunk in this patch. Bug: http://b/159065007 Test: ~/AFLplusplus/afl-fuzz -i tests/files/elf -o fuzz-out -- ./file @@

2020-11-11file: identify Android Binary XML.Elliott Hughes
Android is introducing a new binary XML format that is a drop-in replacement for many existing .xml files written by system_server. Since engineers may be surprised when encountering this new format, add it to the "file" tool to aid identification in the field.

2020-10-29Make it easier to switch regex implementations.Elliott Hughes
One reason to use toybox on the host is to get the same behavior across Android/Linux/macOS. Unfortunately (as we've seen from a few bugs) one area where that doesn't quite work is that toybox uses the libc regular expression implementation. That's fine, and mostly what users want, but those folks trying to get the exact same behavior everywhere might want to switch in a known regex implementation (bionic's NetBSD regex implementation, say) for increased consistency. That actually works pretty well, but portability.h has an #ifndef test for REG_STARTEND before including <regex.h> that gets in the way. To make up for that, this patch removes the unnecessary #include <regex.h> from grep.c itself.

(The bug is that "echo hello \" followed by just enter should end the $PS2 state but it persists when the line is empty because resulting collated line still ends with \ so it wants another line.)

2020-10-15stty: don't mangle c_iflags.Elliott Hughes
Fixes https://github.com/landley/toybox/issues/251 where `stty 300` was mangling c_iflags to 0x300 because even if we don't match a full hex specification of struct termios, sscanf() will have overwritten the first value, which is c_iflag.
