2020-04-04Fix lifetime rules in bracket expansion.Rob Landley
2020-04-02Move #include <linux/*.h> into individual commands, initialize structRob Landley
with memset() instead of = {}, and move TT.alarm to local variable.
2020-04-02Fix macOS build.Elliott Hughes
I'd put the rtc_wkalarm struct in the globals to get it zeroed for free, but since there's no such type on macOS, that breaks the build. Rather than define a bogus struct in portability.h, I've gone for making it an explicitly-zeroed local. (And I've sorted the locals largest-first.) Note that the use of struct rtc_time as if it was the same as struct tm in this code follows the existing code in hwclock, but I worry that we're going to have trouble with that because of the extra tm_gmtoff and tm_zone fields in struct tm. But that's a worry for another day... This patch also removes the CONFIG_CP_PRESERVE from the macos_miniconfig, since that option was removed a while back.
2020-04-02More shell plumbing. Redo of variable storage, add export.Rob Landley
2020-04-01Add rtcwake.Elliott Hughes
Some of the bringup folks are debugging RTC issues and asked for this. Rather than duplicate the weird xtzset dance with mktime, I've factored that out into a new xmktime that takes a boolean for whether to use UTC or local time. Otherwise, the slight cleanup of hwclock.c is entirely optional. The only functional change there is that util-linux 2.34's hwclock uses ISO time format, which is the usual toybox preference anyway, so I've switched it over to that rather than ctime(3).

2020-03-28sed s///: support POSIX I as synonym for iElliott Hughes
POSIX chose I rather than i as the case-insensitive flag for s///, because apparently more seds support I than i. We're allegedly alone in only supporting i. (On the Mac, sed supports neither.) Strictly this isn't *currently* in POSIX, but it's been accepted for issue 8. Bug: https://austingroupbugs.net/view.php?id=779#c2050
2020-03-26du: consistent --help capitalization.Elliott Hughes
2020-03-26du: Implement -bRob Landley
2020-03-23tar: implement --absolute-names.Elliott Hughes
Used by the Linux kernel build when copying kernel headers to kernel-headers.tar.gz. Bug: http://b/152244851
2020-03-18Next round of shell work.Rob Landley
Rethink syntax_err a bit. Try to track top level shell pid for $$ including passing it to nommu subshells. Reset hfd more often so it doesn't climb endlessly. Leak fewer filehandles and detect more filehandle exhaustion errors. Replace skip_quote() with a second mode for parse_word(). Fix $() and implement $(<input).
2020-03-18Fix WARN_ONLY (and the one caller feeding it in the field it was checking).Rob Landley
2020-03-16vi: implement H/M/L.Elliott Hughes
Turns out I move around using these a lot too. I do tend to have very tall terminals...
2020-03-16vi: semi-functional ^E/^U and ^F/^B.Elliott Hughes
The forward movement seems okay (no worse than the equivalent arrow key movement), but I haven't yet worked out how to move the cursor back when necessary. Also fix the location of the cursor in ex mode, and stop showing ex commands in bold.
2020-03-13Pass a few more test suite entries.Rob Landley
2020-03-13Fix "eval x=y", add exec, only prompt if stdin is a tty, search $PATH for scriptRob Landley
2020-03-13Fix various typos.Elliott Hughes
In case I'm not yet in the running for the most pedantic change of this release, I think the "days of the week are written with initial capitals in English" subset of this patch is a strong contender. (Found via `toybox help -a | ispell -l | sort | uniq`.)
2020-03-13readelf: fix interpreter name length check.Elliott Hughes
Looks like I left off half way through this! Also default readelf to n while it's still in pending.
2020-03-12Shuffle code around: eliminate one of two function prototypes, add "static"Rob Landley
to functions that aren't entry points, and collate debug code at top.
2020-03-11Redo NOFORK plumbing so commands like eval/unset can access/edit shell state.Rob Landley
2020-03-11vi: don't keep fd open unnecessarily.Elliott Hughes
As soon as mmap() is done, we can close the fd. xmmap() also will exit rather than return failure so we can remove that check, and fdlength() will fall back to lseek() so there's no need to have the fallback in vi itself. Spotted because the `TT.fd = 0` in linelist_unload() seemed suspicious; -1 would have been more natural.
2020-03-10modinfo: various fixes.Elliott Hughes
I came here because the new -Wno-unreachable-code-loop-increment warning didn't like the for loop on line 86. That loop is indeed not necessary. Use strend() to do a string suffix match. Use memmem() to search. It's available on macOS and Android by default, but it's behind _GNU_SOURCE for glibc, so add that to portability.h. Output the tags in the same order as the Debian modinfo. I've left "parmtype" in even though the Debian modinfo doesn't output it at all. Also fix the tests so that they work on a device that has modules for multiple kernels installed (like my laptop) --- make sure that the two modules we pick come from the same kernel.
2020-03-09Next round of shell plumbing: variable expansion with $IFS.Rob Landley
Not entirely debugged, but more or less there-ish.
2020-03-08cp: fix -D (--parents) (REWORK MINIMAL FIX)Jarno Mäkipää
add: test for -D fix: b/c/d/FILE not copying into a/ with -D option dirname() is not needed when handling FLAG(D) since filename under src or dest should not be changed. github.com/landley/toybox/issues/165
2020-03-05Fix 'for i in one two three; do echo =$i=; done'Rob Landley
2020-03-03Remove another command sub-option.Rob Landley
The question "how does this toybox command behave" should have an answer, not "it depends". (Also, --preserve at the start of a paragraph was confusing config2help.c into thinking it was an option paragraph.)
2020-03-02Switch to FLAG() macros.Rob Landley
2020-03-02Merge realpath into readlink, use xabspath() instead of libc realpath().Rob Landley
2020-03-02Work around gcc trying to be "helpful" again.Rob Landley
2020-03-01readelf: various fixes.Elliott Hughes
Add -e, and stop documenting no-op -W. Fix sign issues, and add a few extra sanity checks. Redo the BE/LE 16/32/64 reading. Remove the NOSPACE=1 from the -l test, and fix the -l code to match the binutils output. Most usefully, this fixes the weird way the NULL section's empty name would cause misalignment in the section to segment mapping output. Add a test for -s (symbol table).
2020-03-01Snapshot of variable resolution implementation. Not remotely load bearing yet.Rob Landley
2020-02-28vi: Rearrange functions, add o, O, IJarno Mäkipää
Place function calls in order so that there is no unneeded declarations, clear some whitespace stuff. Add few commands that are commonly used. cleanup: reorganize functions cleanup: some whitespace stuff add: vi_o vi_O vi_I fix: stop at edges when h and l fix: fix dd not updating screen fix: render after all delete moves
2020-02-28Some compilers get upset if ? : produces different types.Rob Landley
2020-02-27chattr: allow `chattr =`.Elliott Hughes
Also fix another bug where we were testing `set` twice. Fixes https://github.com/landley/toybox/issues/172.
2020-02-26Fix bugs reported by anatasluo: min/range/max were out of order,Rob Landley
min/max weren't being calculated, only print summary when we recieved at least one reply packet. And switch to FLAG() macros.
2020-02-25ps: widen pid_t fields.Elliott Hughes
My desktop and laptop have a pid_max of 262144 now.
2020-02-24Fix fuzz to output lines that didn't match patch context.Rob Landley
(It was outputting the patch hunk where it went, which reverted the context.)
2020-02-11Fix wget version concat segfault.Denys Nykula
2020-02-11chattr: fix exit status, redo the tests.Elliott Hughes
The e2fsprogs chattr(1) returns failure when it fails to do what was asked of it, and so should we. Fixing this then reveals a lot of issues with the tests that were being accidentally swept under the carpet. The bulk of this patch is going through all the tests, removing the duplicates and making the remaining tests more thorough. I've tested this on ext4 and f2fs on a variety of 4.x and 5.x kernel versions (but nothing older). We might need to reduce the list of attribtues we try to toggle, but the more thorough tests use well-supported attributes. I've also fixed the -R test to actually involve a directory hierarchy.
2020-02-06vi: fix pointer pos when at end of lineJarno Mäkipää
Going to $ made draw_page render cursor to wrong line
2020-02-06Basic parenthetical subshell support.Rob Landley
2020-02-06chattr: improve error messages.Elliott Hughes
When chattr fails in production, it helps to see what it was trying to do. Reuse the lsattr format but without the '-'s. Only read the flags if we have any intention of changing them: `chattr -p 123` has no reason to read the flags. Only write the flags back if they actually change: `chattr +a` shouldn't do anything if that flag is already set, for example. Switch -p and -v to perror_msg() instead of perror_exit() in case they're used with -R. (I suspect that the uses of DIRTREE_ABORT are mistakes given -R, but I'll leave them until I actually hit this.)
2020-02-06Remove old GNU style `' quoting.Elliott Hughes
Even GNU don't pretend they're still on 1970s terminals where ` and ' were a matching pair any more.
2020-02-05chattr: reuse toybox argument parsing.Elliott Hughes
Rewrite -v and -p to not use ad hoc argument parsing.
2020-02-04More (subshell) work (not finished), fix {block;} | pipes.Rob Landley
2020-02-03readelf: support large ELF64 files on LP32 systems.Elliott Hughes
2020-02-03vi: fix 32-bit build.Elliott Hughes
2020-02-02vi: Replace linelist with Piece table based designJarno Mäkipää
Replaced dlist linelist with continuous memory blocks. This will allow editing huge files without billion mallocs. File is first opened with mmap() and mapped region is fully described in block_list as one block. Currently "valid" data is described as slices, when first loading file there is only one slice that points to memory existing in block_list. When cutting text, block_list is not freed or modified, but instead slice_list is modified to have "hole" between 2 slices. when inserting new mem_block is added, previos slices are cut in cursor position and new slice is added... Added functions to handling data inside block_list+slice_list insert_str(), cut_str() are used for all delete and add operations text_strrchr(), text_strchr() are used for searching lineendings text_byte(), text_codepoint(), text_getline() are for simple data access Implemented: more or less all previous functionality Implemented more proper file write: file is saved to .swp, blocks are unloaded, file permissions are copied, and atomic rename is called, block is reloaded chmod some defaults(rw-rw-r--) if original file could not be fstat (does not exist) FIX make all tests pass Removed: Some unused functions
2020-02-02Canonicalize the usage: lines for the POSIX toys.Elliott Hughes
This only touches 24 of the 68 toys/posix/ files --- the others were already canonical. Potentially contentious, so worth stating explicitly, is that there were 8 matches for "COMMAND..." amongst all existing help output, with 7 matches for various inconsistent variants involving something with "ARG", so I resolved that in favor of using "COMMAND..." (which is also shorter overall, and avoids nested []s).
