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.

2019-09-05roadmap: more Android/AOSP updates.Elliott Hughes
Update source links, add a bit more rationale.

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.
2019-09-04Add instructions for doing install_flat by hand.Rob Landley
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

2019-08-30blkid.test: allow e2fsprogs' blkid too.Elliott Hughes
This lets me see the _meaningful_ differences between toybox and e2fsprogs, which is probably good for the health of both. I've tried to get the whitespace fixed upstream a few times since 2017, but... (The current differences are that e2fsprogs doesn't support f2fs labels, and outputs reiserfs labels after the uuid rather than before.) On the util-linux front, although my patch earlier this month fixed the tests against util-linux 2.32, I now have 2.33 on my laptop, and that's added a new LABEL_FATBOOT field :-/
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.
2019-08-27Add ASAN=1 to the build, in a slightly different way than Elliott suggested.Rob Landley
I put it in configure, with the other environment variables, instead of in scripts/make.sh. Here's Elliott's original commit comment: ========== Just use `ASAN=1 make test_grep` or whatever. You'll probably want to set $ASAN_SYMBOLIZER_PATH to point to llvm-symbolizer, but Debian makes that annoying by calling the symbolizer /usr/bin/llvm-symbolizer-4.0 or whatever, and ASan refuses to use it: ==43370==ERROR: External symbolizer path is set to '/usr/bin/llvm-symbolizer-4.0' which isn't a known symbolizer. Please set the path to the llvm-symbolizer binary or other known tool. My usual workaround for this is to drop an llvm-symbolizer symlink in the current directory, and I'm happy to automate that in the script to make it require no knowledge of any of this nonsense, but haven't done so in this initial patch. I tested that this is actually working by reverting the grep fix and running `ASAN=1 make test_grep`.
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")
2019-08-23Trivial style fixes while I was looking at main anyway.Rob Landley
2019-08-23Fix "ln -s toybox potato; ./potato" unknown command problem.Rob Landley
(Commit 7771e94e2a08 broke it.)
2019-08-22Add scripts/mkroot.sh and makefile changes for "make root".Rob Landley
Not in help text yet. Needs sh and route enabled in pending to do much. todo: work through the scripts/install.sh $PENDING list and add native toolchain support.
2019-08-22Quiet "make clean" so it doesn't fill a whole screen with output.Rob Landley
2019-08-21Add some 2>/dev/null to tests that produce gratuitous stderr output.Rob Landley
2019-08-21Add xgetline (which the last sh checkin used, oops).Rob Landley
2019-08-21Fix the unshare probe.Rob Landley
2019-08-19Tiny cleanup, net two lines shorter.Rob Landley
2019-08-19Fix bad test.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
2019-08-15find.test: allow any error message about symlink loops.Elliott Hughes
glibc says "Too many levels of symbolic links", but BSD says "Too many symbolic links encountered". Until it becomes a problem, allow any error message.
2019-08-15dd: fix skip= with short reads.Elliott Hughes
Subtract the amount we actually read, not what we asked for.
2019-08-15linestack.c: fix buffer length.Elliott Hughes
GCC 8.2 (which my laptop appears to have been quietly upgraded to) points out that the %04X of an int might actually take 8 characters; between that, the "U+", and the trailing NUL, we're gonna need a bigger boat...
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.
2019-08-12find.test: fix flakiness.Elliott Hughes
Don't depend on directory iteration order in a test.
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.
