2021-04-23cpio: Don't lchown() if -t is specifiedYi-Yo Chiang via Toybox
When using -t to inspect an archive, cpio would try to set the owner of any symlink in the archive, even though the symlink wasn't created by the command previously. This would lead to two results, either the command fails with a "No such file or directory" message when trying to lchown() the symlink path, or an existing file, with the name of the symlink, is lchown()-ed. Guard the lchown() function call with a "if (!FLAG(t))" block, and add regression test for this.

2021-03-15chmod: fix +X.Elliott Hughes
I broke this when I added the masking out of the S_IFMT bits for macOS, because string_to_mode needs the full mode with those extra bits, specifically so that it can recognize directories for +X to work. I've duplicated chtest rather than change chtest to explicitly set the modes to 000 before running the given chmod command because I didn't want to touch *all* the tests and obscure the addition of just one.
2021-03-13Commit 3b9cfa70db needed some cleanup I forgot to do, oops. Elliott stumbledRob Landley
across one of the issues I forgot to fix. Added a couple comments and renamed a variable to try to clarify the code while I was there.
2021-03-12Fix grep bug testing errno before check statusRobin Hsu
It's legal for a system call to set non-zero errno and return a good status. The caller (grep) should check return status first. Test: 2000 loops of greping 1000+ lines each loop Signed-off-by: Robin Hsu <robinhsu@google.com> Change-Id: I55f7cd5d8a6289c5e8a21ed3057e995a75b9b4fa

2021-03-09tar: fix base-256 output.Elliott Hughes
A tar file created by toybox tar with values large enough to need base-256 rather than ASCII octal caused a tar reader to crash, and caused GNU tar to complain. I note from the docs at https://github.com/libarchive/libarchive/blob/master/libarchive/tar.5#L326 that they imply that only the top *bit* should be set to indicate this format, not the whole top byte, to give a 95-bit or 63-bit field. But I don't think we can hit that in practice? Bug: http://issuetracker.google.com/181683612

2021-02-20Fix df on macOS.Elliott Hughes
On Linux, struct statvfs' f_bsize and f_frsize seem to be interchangeable. On macOS, they're wildly different. f_bsize is the "preferred length of I/O requests for files on this file system" (corresponding to statfs::f_iosize), and f_frsize is the "size in bytes of the minimum unit of allocation on this file system" (corresponding to statfs::f_bsize. POSIX appears to say nothing about the interpretation of these fields, but man7.org's statvfs(2) page is quite clear that statvfs::f_blocks, for example, is in units of f_frsize, not f_bsize. This is the only place in the tree where we use statvfs::f_bsize (other than the stat(1) output that's supposed to be f_bsize and that has a corresponding f_frsize dual anyway. I've removed the Apple-specific #define f_frsize in portability.h because that seems to have been from my previous attempt to understand what was going on here. The output of the relevant stat(1) fields on macOS are the same before/after this patch. This makes toybox df's output match the system's df on a MacBook Pro running macOS 11.2.1. Tested on a Raspberry Pi 400 running Linux too, where I see no change in the output before/after this patch.

2021-02-09ulimit: include descriptions and units.Elliott Hughes
Also reorder the --help output to separate the "whats" from the "hows", as with other commands that have lots of options, and add units to the help too.
2021-02-08Yi-Yo Chiang reported that readlink() failures could corrupt archiveRob Landley
by not writing as much payload as the header promised.
2021-02-08Have xclose() perform the fd != -1 test.Rob Landley
2021-02-07Remove unused function.Rob Landley
Ethan Sommer noticed that chown is using chgrp_main() due to OLDTOY, so the wrapper function isn't needed.

2021-02-01Minor tweak.Rob Landley
2021-02-01rm: Check file existence with lstat() explicitly if "-f" is specifiedYi-Yo Chiang
Instead of unlink() && check errno, call lstat() explicitly to check file existence if "-f" is specified. There is a regression when if the path to be removed is nonexistence and within a readonly filesystem, then unlink() could set the EROFS errno instead of ENOENT, thus screwing up the output of `rm`.
2021-02-01The new TEST_GLUE config symbol for [ ] can't have TOYBOX prefixRob Landley
or else singlemake enables it for all commands. (I was trying to move it out of the command namespace, but it's not a global config option either...)

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.
2020-12-11The "fall back to C.UTF-8" check was backwards, and make TOYFLAG_LINEBUFRob Landley
configurable.
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.)

tests to catch this. While there add -k to test sticky bit.

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.
