2015-10-27Fix ls error message for chmod -r directories.Rob Landley
Also, if you mkdir "$(echo -e "one\ntwo"); chmod -r one*; ls -q one* it honors -q.
2015-10-27Install without a mode should use 0755, and check FLAG_preserve instead ofRob Landley
the global so "install -g 0" doesn't alias to "cp --preserve 0" and error out. through to --preserve 0"
2015-10-22Auto-size df columns.Elliott Hughes
On Android, the filesystem column is pretty wide. Actually measure the widths.
2015-10-05Fix bug in od that screwed up position indicator on arm and mips.Rob Landley
2015-09-29Make defconfig build for nommu.Rob Landley
Adds XVFORK() macro, teaches xpopen_both() to call /proc/self/exe with NULL argv (and converts cpio -p to use that), adds TOYBOX_FORK guards to some unconverted commands.
2015-09-23Add xvfork() as a static inline and use it from various places.Rob Landley
Note: vfork(), like fork(), can return -1 if too many processes, and we should notice and fail loudly.
2015-09-12Fix a find segfault.Rob Landley
Elliott Hughes found a bug https://android-review.googlesource.com/#/c/170020/ and Daniel K. Levy worked out the problem: the user/group/newer arguments to find weren't consuming their arguments when not checking the results of their comparison (because an earlier test had already caused their parenthetical group to fail). This confused the argument parsing logic and could lead to segfaults. I applied a different fix that reorganized the existing tests instead of adding a new test. (Looks like a big commit but it's mostly whitespace due to extra curly brackets changing indendentation levels.)
2015-09-11Replace toys.exithelp with help_exit() in lib.Rob Landley
2015-09-08Squish a warning in pending.Rob Landley
2015-09-07Remove prompt argument from yesno(), caller can fprintf(stderr, "blah") itself.Rob Landley
This fixes the build break, the change to yesno() prototype accidentally got checked in last commit. (Oops, sorry.)
2015-09-06Switch HR_SI to HR_1000, make binary the default, make HR_B only affect bytes,Rob Landley
and update the tests.
2015-09-05ls -h support.Elliott Hughes
It turns out that people are anticipating the switch to toybox ls from toolbox ls on the assumption that this will finally bring -h support. Let's not disappoint. I've merged two existing buffers in listfiles whose uses didn't overlap into one. It may be possible to cram this into toybuf with the other stuff, but it didn't seem worth the extra complexity for 64B of stack, especially since we were already living with that for time formatting anyway.
2015-09-05df -h and -H.Elliott Hughes
This doesn't address the lack of support for a variable-width "Filesystems" column, but it doesn't make the current situation any worse either. This is the last of the missing -h options. The other commands with -h also have --si, but only for df did it get a corresponding short option (and I've never personally used --si on du or ls, so let's wait until someone actually cares).
2015-08-31ls -l user/group/security context should be left-aligned.Elliott Hughes
Right-aligned looks pretty good to me, but it's not what anyone else does.
2015-08-30Fix mv on overwrite.Elliott Hughes
We need to remove the destination, not the source, to be able to overwrite.
2015-08-25Static analysis from Hyejin Kim found possible pointer underflow.Rob Landley
Now that the kernel's 128k environment size has been lifted, it might be possible to feed in a gigabyte of suffix so argv[2] is enough larger than argv[1] that char *s decrements past NULL and points to arbitrary high memory (I.E. strlen(suffix) > (long)base), at which point the base > s test is defeated and we strcmp() against a wild pointer. Which is read only anyway and on 64 bit you probably couldn't hit any interesting addresses, but the fix is easy enough: compare strlen values instead of pointers. So do that instead.
2015-08-15Kylie McClain pointed out that env should clear variables with NAME= by itself.Rob Landley
2015-08-11Fix more date bugs.Elliott Hughes
Correctly and portably check for non-normal dates, and explicitly show the "before" and "after" dates (in the format of the user's choosing). Clear the struct tm in date_main rather than parse_default because on one path the struct tm is actually initialized. Explicitly clear the tm_sec field in parse_default because -- experiment shows -- that should not be preserved. Only do the "what does this 2-digit year mean?" dance if we actually parsed a 2-digit year. Show the right string in the error message if strptime fails. Also add more tests, and use UTC in the tests to avoid flakiness.
2015-08-11Bugfixes from Elliott Hughes: debug code got checked in (oops) andRob Landley
uninitialized trash in struct tm fields could segfault glibc's strftime().
2015-08-08Different tools have different ideas about what human-readable outputElliott Hughes
looks like. dd uses "7 MB" where du uses "7M", for example. this patch adds flags, similar to the BSD humanize_number. most callers will pass 0.
2015-08-08Fix ls -l user/group field ordering.Elliott Hughes
It's user then group, not the other way round.
2015-08-08Teach date @unixtime[.fraction], switch -s to be -D (matching busybox andRob Landley
not stomping on gnu's "an extra argument tells it to set the time so let's add -s to do the same thing" extension). Nanoseconds aren't uniformly supported by these apis, so had to stick it in GLOBALS() and pull it out later. Awkward, open to suggestions for a better way. (Also, the setting API is microseconds, not nanoseconds. Collect nano, convert to micro so we can switch APIs later without changing date's external UI again.) Oh, and shrink really_long_name_mktime() with a for() loop (and rename it) although I may go back and redo that for portability to hypothetical libraries if I can convert this mess to struct timespec with proper nanoseconds support. But that needs an extended strptime() which needs an extended struct tm, and between us and that is convincing posix computers got fast enough to care about fractions of a second. (Yes, I'm aware gnu added %N to date without adding it to strptime, implying they reimplemented strptime longhand inside date. I'm not doing that.)
2015-08-08Reject invalid dates in date(1).Elliott Hughes
Humans get upset when date(1) lets mktime(3) work out what the 99th day of the 99th month would be rather than rejecting the invalid date. For the subtly wrong cases, rather than get into the leap year business, let's rely on localtime_r(3).
2015-08-02Mark command-local functions static.Rob Landley
2015-08-01Replace xcheckrange() with atolx_range()Rob Landley
2015-08-01Move strlower() from find to lib.Rob Landley
2015-07-13Produce an error message for "cat /mnt", not just return code.Rob Landley
2015-07-10find: add -inum optionGreg Hackmann
-inum is a commonly implemented extension to search by inode number. Linux's fs-layer tracepoints log many events in terms of inodes, so "find -inum" is useful for mapping those events back to specific files.
2015-07-09There is a typo in mkfifo.c for __Z__ option.Sameer Pradhan
2015-07-06Avoid integer overflow with insane input data.Rob Landley
2015-07-05Kylie McClain pointed out that -z affects both input and output.Rob Landley
Can't say I'm happy with the API (-z and -Z to keep them independent would be nice), but compatibility with what exists trumps having a good API...
2015-07-04Actually set time with touch -d and -t when you don't specify nanonseconds.Rob Landley
There's a nanoseconds field value that says use current time, which I set but forgot to clear in the right places. (Oops.)
2015-07-03First pass on cp --preserveRob Landley
2015-07-01Improve -Z error reporting.Elliott Hughes
The most likely reason for setfscreatecon to fail is that you don't have permission, and that's reported by the write return EACCES. There isn't really a "bad" context; they're just strings. Before: $ adb shell mkdir -Z x y mkdir: bad -Z 'x' After: $ adb shell mkdir -Z x y mkdir: -Z 'x' failed: Permission denied Other than this, the ToT mkdir works fine with SELinux.
2015-06-29mkfifo -ZRob Landley
2015-06-23Don't segfault if none of the file arguments to ls exists.Rob Landley
2015-06-23Don't depend on malloc(0) to return non-null.Rob Landley
2015-06-23Fix ls so spacing is right for ls -l, -o, -g, -og, -ogZ, -lZ, -gZ, and -oZ.Rob Landley
2015-06-06Last grep commit broke non -r use of grep. Oops.Rob Landley
2015-06-02Make "printf --" and "printf ---" work.Rob Landley
2015-05-31Move the magic list of commands needing cleanup from toys/pending/READMERob Landley
to greppable TODO annotations in the individual files. (grep -riw TODO)
2015-05-28Attempt to fix the mkdir LSM race.Rob Landley
Doing a world writeable mkdir and _then_ adding a label seems like a race window, so set the global "create stuff with these labels" context, then do the creates.
2015-05-21ls -lZ wasn't putting a space before the xattr output.Rob Landley
2015-05-21mkdir: Fix argument of option -ZJosé Bollo
2015-05-20Make "grep -r regex" work on implicit "." if no files specified.Rob Landley
2015-05-19Add -Z support to mkdir, based on a patch from Jose Bollo.Rob Landley
I have no idea why -Z isn't showing up in mkdir --help when enabled, I need to look at that...
2015-05-19Adapted patch from José Bollo to do the "tonight we're gonna api likeRob Landley
it's 1999 and every path ever is from cwd or root" api versions for sockets and as a fallback of the open fails. There are still some holes (symlink to socket with -L will give you info about the symlink, not the socket, and symlink to a file you can't open will give you info about the symlink, not the file) but the correct fix is to make O_PATH work in the kernel for the LSM functions. (If we can read this data by path, we should be able to read it by O_PATH. We should not need two codepaths for this.)
2015-05-18Switch id over to new infrastructure, switch id to use FORCE_FLAGS, andRob Landley
make lib/lsm.h auto-include from toys.h.
2015-05-18Fix "ls -Z . toys" segfaulting, because preprocessing skipped.Rob Landley
strwidth() got called on ->extra which was NULL. Had some other bad effects ala "ls -sk file1 file2 file3" ignored the -k. This should fix that too.
2015-05-18Recent commit broke ls -R (test reversed), and "ls -R singledir" shouldRob Landley
show label: at the start (yes, even "ls -R" in an empty dir).
