2019-09-15The ! changes I meant to check in last time were applied ot the wrong dir.Rob Landley
(oops.)
2019-09-15Fix tar files that end sparse (need to call truncate), and display/exportRob Landley
length of sparse files properly.

2019-09-13timeout: fix exit status for sneaky subprocesses.Elliott Hughes
There's nothing to stop a subprocess from catching our SIGTERM on timeout and exiting, causing us to incorrectly report that it didn't time out. Android's ART has a utility that does exactly this. Explicitly catch this case, and add corresponding tests. Bug: http://b/141007616
2019-09-12Minor cleanup.Rob Landley
2019-09-11Add NOP -f, -g#, and --no-backup-if-mismatch options.Rob Landley
(All ignored, because they disable stuff we don't do.)
2019-09-11Add q123 exit code, add Q, fix "sed ' ! '" bad error message.Rob Landley
2019-09-09ls: fix spacing of -lZ and --full-time.Elliott Hughes
Two more spacing bugs here, one before the security context for -Z, and one after the size with --full-time. Before: $ ./toybox ls -lZ --full-time Config. -rw-r----- 1 enh primarygroup? 56162019-09-07 21:09:32.892215100 -0700 Config.in After: $ ./toybox ls -lZ --full-time Config. -rw-r----- 1 enh primarygroup ? 5616 2019-09-07 21:09:32.892215100 -0700 Config.in
2019-09-09vi: added support for tabsJarno Mäkipää
Add: tabs, follows tabstop variable currently hardcoded to 8. Should be adjustable with :set tabstop N according to man page fix: search, issue with searching substring that is more left than cursor position on following lines.
2019-09-08make "for i in" work.Rob Landley
2019-09-07host: cope with large DNS responses.Elliott Hughes
DNS responses were limited to 512 bytes back when they were UDP only, but if you have a TCP connection you can get up to 64KiB. Also use the existing constant for the size of rrname. Also update the help text. Also consistently use `sizeof(T)` rather than `sizeof T`. Also use consistently use `ARRAY_LEN`. Fixes #56. Test: `toybox host value.testing.express`
2019-09-07vi: small fixes.Elliott Hughes
I really needed to be able to edit a file on the device, and this was the nearest thing handy, and it turns out to be more or less usable for basic editing, so... Support cursor keys. Support :q (since there's currently no record of whether the file's modified or not, :q is the same as :q!). Add 'A' to insert at end of line. Add 'n' to find next after '/'. Fix backspace all the way to get out of ex command mode. Fix escape sequences to not hard-code assumptions about the terminal's default background and foreground colors. Fix 'spesial' typo for 'special', and remove explicit array sizes.
2019-09-07md5sum: don't allow broken sha-3 sums.Elliott Hughes
If you accidentally configure the sha-3 sums on, but don't enable libcrypto, you'll get toys that just output md5 sums instead. This patch doesn't cause a build-time error (my original plan), but does at least ensure that toybox refuses to include incorrect sha-3 sum implementations.
2019-09-04Factor out AF_UNIX socket openting, use FLAG() macros, xsocket() alreadyRob Landley
does CLOEXEC (should fix macos build).
2019-09-04find: support -printf \0 octal escapes and \c.Elliott Hughes
I think when I wrote this I tested the named escapes like \n and hex escapes, and when I found \x wasn't supported I didn't even think of octal. And I only learned about \c when I was looking at echo and printf to compare their escape implementations a few weeks back. Add the missing escapes and corresponding tests. Fixes #139.
2019-09-04ls: fix -Z, add a test.Elliott Hughes
This broke a netd test (but sadly in postsubmit rather than presubmit). Also add a trivial test that would at least have caught this bug. Bug: http://b/140453237
2019-09-04DIRTREE_STATLESS doesn't have to test 3 stat fields, it sets a flagRob Landley
2019-08-30ls: fix recent regression.Elliott Hughes
Commit c26870dab3462c6176936384b090df6b9ba46dee broke ls' error reporting for files that don't exist. `ls $F` is used by some as an equivalent of `test -e $F`. This patch also adds a regression test.
2019-08-30find: fix -name corner case.Elliott Hughes
This fixes the case where someone's done something (weird) like: find src/*.c -name foo.c Previously the match would fail because one side of the comparison was already a path.
2019-08-29diff and patch: support special characters in filenames with quoting as well ↵William Haddon
as unusual timestamp formats After further research and testing, I've produced a patch which handles all filenames with special characters by copying the GNU quoting behavior, and also treats anything following a tab as a timestamp. This increases both ability to handle possible filenames and ability to apply patches found in the field. In diff, quote and escape filenames according to the following rules. * Surround the filename with quotes if it contains a byte less than 0x20, a byte greater than or equal to 0x80, space, backslash, or quote. * Replace alert, backspace, form feed, newline, carriage return, tab, vertical tab, backslash, and quote with \a, \b, \f, \n, \r, \t, \v, \\, and \", respectively. * Replace other bytes less than 0x20 or greater than or equal to 0x80 with a backslash followed by the three octal digits representing the value of the byte. * Treat valid UTF-8 characters involving sequences of bytes greater than or equal to 0x80 the same as other sequences of such bytes. In patch, process quoted and escaped filenames according to the following rules. * If the filename does not begin with a quote, do not modify the filename. * Remove quotes surrounding the filename. * In quoted filenames, replace \a, \b, \f, \n, \r, \t, \v, \\, and \" with alert, backspace, form feed, newline, carriage return, tab, vertical tab, backslash, and quote, respectively. * In quoted filenames, replace a backslash followed by octal digits with the byte with that value in octal. Also, in patch, treat anything on a +++ or --- line following a tab character after the beginning of the filename as a timestamp, rather than part of the filename.
2019-08-29Fix sh handling nested if/else/elif statements alaRob Landley
if true; then if false; then echo one; elif echo two; then echo three; else echo four; fi; fi
2019-08-28Fix find(1) after c26870dab346.Elliott Hughes
Unlike ls, find does treat ENOENT specially. Add an extra test (and fix the behavior) for the case of ENOENT for a path provided on the command line --- unlike other ENOENT cases (typically dangling symlinks), ENOENT for a command line argument should report an error. Also remove obsolete `|sed` from the symlink loop test.
2019-08-26xargs: add --max-args synonym, -o option, and fix -p.Elliott Hughes
The Linux kernel uses the --max-args synonym for -n. Barbarians who use vi need xargs' -o to be able to do something like: find -name xargs.c | xargs vi # Sad vi. find -name xargs.c | xargs -o vi # Happy vi. The -p option needs fixing to read from /dev/tty because stdin is otherwise occupied in xargs. I think xargs is the only place that needs this, so it didn't seem sensible to make all callers to yesno() be specific about which they wanted, hence the new function. Also remove the documentation for the build-time XARGS_PEDANTIC option which isn't actually implemented. Also add a TODO for -P (which is used by at least one script in the Linux kernel).
2019-08-26Try to make ls failure more graceful. Print ? ? ? entries instead of error msg.Rob Landley
Tweak DIRTREE_STATLESS so it returns zero stat for any error (I'm testing that dev, ino, and blksize are all zero), and fill in file type from readdir()
2019-08-23man: fix help, align -k output, and fix double close.Elliott Hughes
The "info" pages are something very different from the "intro" pages :-) do_lines already closes the fd. Also improve the error message for `man`.
2019-08-23getconf: remove workaround for old NDKs.Elliott Hughes
macOS remains awkward, though, but this retains our Android/Linux behavior and is closer to the platform's getconf(1) for macOS. Strictly macOS denies all knowledge of UIO_MAXIOV, but the "undefined" you'll get from this patch seems closer than the "1024" we used to give.
2019-08-23rm: error message consistency.Elliott Hughes
Before: $ ./rm rm: Needs 1 argument $ ./rmdir rmdir: Needs 1 argument (see "rmdir --help") After: $ ./rm rm: Needs 1 argument (see "rm --help")
2019-08-19Tiny cleanup, net two lines shorter.Rob Landley
2019-08-19echo/printf: expand test cases, fix \x corner cases.Elliott Hughes
The behavior with "\xAV" (where the second hex digit is invalid) is different from the behavior with "\xVA", and echo and printf differ from each other.
2019-08-18Next round of shell plumbing.Rob Landley
You can now run: echo hello; if true; then echo hello; fi; while true; do echo hello; done It's got the start of for loops but needs environment variable resolver to do much with them.
2019-08-15Fix two typos.Elliott Hughes
2019-08-15Switch makedevs to new GLOBALS naming.Rob Landley
2019-08-15dd: fix skip= with short reads.Elliott Hughes
Subtract the amount we actually read, not what we asked for.
2019-08-13Return md5sum/sha1sum to the slightly slower but more explicit versionRob Landley
(revert afe951b19c0f with the table of magic constants). If you want speed, there's already a config option to use the libssl version instead.
2019-08-12sort: move off get_rawline.Elliott Hughes
This was the last user of get_rawline, which lets us remove it.
2019-08-12blkid: add -s, SEC_TYPE, f2fs LABEL, and fix vfat/ntfs UUID.Elliott Hughes
This gets the tests passing with both toybox and util-linux 2.32.1 blkid. We use -s to get around the fact that we still don't support ntfs' $VOLUME_NAME attribute.
2019-08-09find: fix dangling symlink behavior.Elliott Hughes
ENOENT is ignored, but other errors are reported.
2019-08-09lsof: simplify octal mode display.Elliott Hughes
Since this masks, it doesn't actually have the same bug as e5942a8c90c2f52550496fdf08efddb564d8e5a3, but we may as well fix the other example of that questionable idiom while we're thinking about it...
2019-08-09losetup: fix the race.Elliott Hughes
There's a race between LOOP_CTL_GET_FREE and LOOP_SET_FD. Work around it by just retrying if we get EBUSY on the LOOP_SET_FD call. This is what similar code in ChromeOS already does. Bug: http://b/135716654
2019-08-09Split out run_function() and free_function(), add start of _TOYSH_LOCALSRob Landley
marshalling for vforked subshells, fix rc returned from run_pipeline for variable assignment. (Well, sort of: X=$(false) still needs rc = 1.)
2019-08-04Make "if true; then echo hello; fi" work. More work on redirection.Rob Landley
2019-08-04Add TOYFLAG_MAYFORK and annotate a couple commands.Rob Landley
A TOYFLAG_NOFORK command must run in the context of toysh, but a MAYFORK can either run standalone or run in the toysh process. MAYFORK means it cleans up after itself: no leaked resources (malloc, mmap, filehandles, etc), even in error_exit() paths that would longjmp() back to the shell. It also doesn't discard anything we need to retain (don't close stdout, change toys.optargs[] so we can't free it, etc)...
2019-08-03Fix a bug report from E5ten: stat of a file with suid or sticky bit setRob Landley
output 5 digits of octal stat data instead of 4, due to hardwired leading 0 instead of %04a sprintf prefix.
2019-08-02Next round of infrastructure. Start of redirect logic and runtime flow control.Rob Landley
2019-07-31Move the empty regex workaround into xregcomp.Elliott Hughes
No current caller except grep needs this, but consistency seems like a good idea. Also change the xregcomp error message to be a bit more human-readable, rather than mention an implementation detail.
2019-07-31man: switch to xregcomp.Elliott Hughes
All regcomp callers are now going through xregcomp.
2019-07-30Fix signed typecast bug.Rob Landley
We use (char *)1 and (char *)2 to indicate errors (they can never be valid pointers because both malloc() and mmap() return aligned memory and those align down to NULL, plus Linux maps 4k at the bottom to catch null dereferences anyway), and then typecast it to long (trusting in LP64) to do an integer <=2 comparison... except that needs to be UNSIGNED long or else pointers in the top half of the virtual memory space become negative and the <=2 false positives them as errors. (Oops.)
2019-07-29grep: fake GNU behavior for non-POSIX empty regex.Elliott Hughes
POSIX says there's no such thing as an empty regular expression. The grammar excludes the possibility: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html BSD agrees with POSIX, and Android and macOS' BSD-based implementations reject the empty regular expression. GNU apparently disagrees. Luckily, BSD does accept the empty *sub* expression `()`, despite their error message for REG_EMPTY being "empty (sub)expression". This is presumably a bug, except there's explicit code to support it that is at least 26 years old: https://github.com/freebsd/freebsd/blame/master/lib/libc/regex/regcomp.c#L383 This workaround also works fine with glibc. If we want GNU behavior, I'm struggling to come up with another way to fake it. If we want POSIX behavior, we could easily just add a check to reject "" on glibc. Also switch to xregcomp().
2019-07-25killall: implement -w.Elliott Hughes
This isn't currently used in AOSP, but it is used in some of the other codebases I can easily search, and it's a better fix for test flakiness than inserting a sleep.
