Read any PT_NOTE sections to look for NT_GNU_BUILD_ID or Android API
level notes. I deliberately didn't NT_GNU_ABI_TAG because it's noisy --
every Linux executable has one -- but not something most command-line
users will have any use for. (And you can ask readelf(1) anyway.)
Also read the section headers to implement "stripped"/"not stripped".
This patch removes "uses %d libs" because it was actually just counting
dynamic sections in the ELF file, and there are only 0 or 1 of those in
a valid ELF flie. (If you really want this functionality, you have to
*parse* the dynamic section looking for the DT_NEEDED entries. But that's
more of a job for readelf(1) than file(1).)

(Ubuntu's netstat is left justifying the inode field, and they're wrong.)
|

7ca5dc4232b9ac5ee5cd25c8b5b33a58904cd251 didn't switch all callers over
to the new functions.

Spotted while trying to diff netstat -nt against toybox netstat -nt.
|
|
(I forget who reported this bug, wasn't me.)

More's sigatexit handler needs to distinguish between normal exit and exit
due to receipt of a signal.
Change tty_sigreset to look at the signal number too, so that pressing 'q'
to exit top doesn't cause its exit status to be 128.
|
|
And add a test.

We were doing two 32-byte memset()s instead of two 16-byte memset()s.
'dir' referred to the instance (array of 2) and not the struct type.
Add some test coverage for diff, including a case that hit this bug.
The bug was found by running cp.test under AddressSanitizer, since it
happens to use diff.
|
|
both did it) so use getbasename instead.
|
|
Fix memory leaks in regex. Simplify regex check (if we matched, subexpression
had to match). Don't exit() from a command, set exitval and return.
|
|
I deliberately didn't do this first time round because for me our lsof
is already 10x faster than traditional lsof, and caching means we potentially
give less information about a socket that's created while we're running.
It turns out that traditional lsof caches anyway, so I guess nobody cares.
This also fixes a mistake where lsof used CFG_FREE instead of CFG_TOYBOX_FREE.

copying itinto a second variable. Also add error message for empty ( )
|
|
eliminate syntax_error() function (just call error_exit() directly),
eliminate advance() wrapper, pipe expected error messages in test to /dev/null
|
|
All tests pass now; this fixes the 2 remaining failures, including a
segfault.
The structure of the code has changed a lot -- instead of having a tiny
function per operator, we have eval_op() which does common type coercion
and then evaluates the operator. I tried writing it a couple different
ways, and this was the cleanest.
The OPS table now contains the operator string, precedence level,
signature for type coercion, and operator ID.
|
|
expr now uses the precedence table specified by POSIX, implemented using
the "precedence climbing" algorithm. See the references at the top of
eval_expr().
This fixes 3 of 4 failing tests.
I also added more tests for correct behavior and for syntax errors.
This includes a new test exposing a segfault, related to type coercion.
|
|
(This should fix allyesconfig.)
|
|
handle infinite depth. Fix docs, tweak dirtree_handle_callback() semantics,
remove dirtree_start() and don't export dirtree_handle_callback(), instead
offer dirtree_flagread(). (dirtree_read() is a wrapper around dirtree_flagread
passing 0 for flags.)
|
|
- shorten error messages
- replace mk_rq with sprintf
- remove struct and defines
- change unsigned int to unsigned
|
|
next few fields in the order the other implementation outputs, fewer commas,
fix a big where big endian executable type wasn't detected right,
and fix the filehandle leak.

major/minor/makedev, but glibc has vowed to break existing programs
(https://sourceware.org/ml/libc-alpha/2015-11/msg00253.html)
and replace it with _another_ non-standard header (not in posix or lsb),
so let's just add functions to lib/ that do the transform ourselves.

The clang FORITFY implementation doesn't like pointer signedness mismatch.
"What mismatch?", you say. "The historical bug in LP32 Android that left
it with a signed socklen_t".

- per POSIX, 'cannot open' must be in the 'type' string if open() fails
(both EPERM and ENOENT); we only do that if open() succeeds and fstat(fd)
fails.
- symlink detection (as per POSIX) won't work: opening them O_RDONLY
results in following the link, then we fstat() the fd.
- file 'FIFO' causes a hang; open() won't return till there's a writer.

port 80 is not used.

Accept multiple -p, inline filter_matches, convert misleading "char* a, b" to
"char *a, b", use readfile() to read a file, use DIRTREE_SHUTUP, don't need
{ } around a single line, don't modify command line environment space
(which changes what ps/pgrep sees).

Unlike the POSIX file(1), there's no magic file here, just hard-coded
common (non-obsolete) file formats. Personally most of my use of file(1)
is as a one-line readelf(1) summarizer, so although I assume a full POSIX
file(1) is out of scope (because just the database would likely be larger
than all the rest of toybox), a subset that only supports in-use file types
actually covers most of the use cases I encounter personally.
Also fix peek_be/peek_le.

Pathnames may be longer than the name field in the header, so use
strncpy() instead of xstrncpy() to avoid bailing out.
Also add unit tests to ensure proper handling of short and long
pathnames.

If we're fixing warnings in pending...
|
|
- Adjust to 80 columns
- remove a useless function(strchr_nul), variable, type casting and
compile warnings(fgets)
- clean up netstat command option condition
- change useless double pointer to single point and dynamic memory
allocation to static one
- fix a ambiguous return type and typo
|
|
While I'm there, pack the ps help text, break out TOP_COMMON (todo: update
config2help to collate that properly), add -o CPU showing which processor
this pid is running on, implement -o C (it's %cpu without the fractional
part), add -o %MEM, fix header padding.

Needs testing and a few more options connected up.
