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.

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.

Not entirely debugged, but more or less there-ish.

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.

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.)

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).

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

Also fix another bug where we were testing `set` twice.
Fixes https://github.com/landley/toybox/issues/172.

min/max weren't being calculated, only print summary when we recieved
at least one reply packet. And switch to FLAG() macros.
|

My desktop and laptop have a pid_max of 262144 now.

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.

Going to $ made draw_page render cursor to wrong line

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.)
|
|
Even GNU don't pretend they're still on 1970s terminals where ` and '
were a matching pair any more.
|
|
Rewrite -v and -p to not use ad hoc argument parsing.

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

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).

Found by GCC 9:
toys/lsb/mount.c:188:22: warning: '%s' directive argument is null [-Wformat-overflow=]

Document all the attributes, and take less space doing so.
Switch to CAPITALS for user input in the synopses.
Don't imply that this is only for ext2 (but also don't try to list the
subset of file systems that do support which subset of attributes).

(A git build takes it from "git describe".)

makes those two remaining tests pass.

Test file integrity after load, move, delete and save+exit. Drawing
of buffer is not tested yet.
Added -s script option, accept file that is run as startup script of
commands. File is parsed byte at time and handled as you had typed it.
If EOF has been reached without editor close command, editing is
continued normally using keyboard. This functionality is in vim and
neovim, but not in POSIX vi standard. nvi (vi used in some macs) has
-s with different meaning...
Some simple tests added, dw last line test fails, so test is disabled.

The kernel script scripts/kconfig/merge_config.sh uses cp -T.
(Also sort the options into alphabetical order while adding -T, so that
eyeball binary search actually works when trying to find an option! Oddly,
they all show in reverse order because there's a bug in the help text
generator, but that's a problem for another day...)
|
|
Add support for setting projid in chattr, and dumping it in lsattr.
Also fix the lsattr output formatting, and undo my well-intentioned
sorting of the flags because that broke the ordering in the lsattr terse
output.
|
|
Also update help to include flags that were already added. Remove
useless duplicative comments. Swich to FLAG macros.
|
|
This isn't in POSIX, but Debian and macOS' cal(1)s both do this, and
it's annoying to have to run date(1) separately.

fix: first line delete
fix: delete with e move
fix: statusline 1 row lower, remove eol
cleanup: use dlist_pop on delete
cleanup: move globals into GLOBALS

^D is the opposite of ^U in vi (the ^D/^U pair is the half-screen
version of ^F/^B). ^C is unbound in vi. It's pretty surprising for these
to cause toybox vi to exit, and it's annoying as long as toybox vi
unconditionally exits rather than checks whether there are unsaved
modifications!
(I'm tempted to implement ^D/^U and ^F/^B, but I don't want to make
Jarno's rebase of his in-progress changes any harder.)

used uninitalized" warning, move flow control character detection to the
right place, change scratch zeroing to the same way main() does it.

This is false on ILP32 targets with 64-bit time_t.

-w was added recently. The change in behavior so we now always fork
means that it's needed in more cases too: other implementations of
setsid(1) only fork if getpgrp() != getpid(). This broke a script, which
is what made me notice the missing help.
This seems to have been an accidental change, and is contrary to what
the util-linux setsid(1) man page says: "The command calls fork(2) if
already a process group leader. Otherwise, it executes a program
in the current process", but whether we change our behavior or not, we
should document the new option.
