A version of this patch was originally sent to me by se@, matching behavior
from newer versions of GNU grep.
While there have been some differences of opinion on whether stdin should be
closed or not after depleting it in process of -f, I've opted to leave stdin
open and just let the later matching stuff fail and result in a no-match.
I'm not married to the current behavior- it was generally chosen since we
are adopting this in particular from GNU grep, and I would like to stay
consistent without a strong argument to the contrary. The current behavior
isn't technically wrong, it's just fairly unfriendly to the developer-user
of grep that may not realize their usage is trivially invalid.

It was an old TRE that had plenty of bugs and no performance gain over
regex(3). I disabled it by default in r323615, and there was some confusion
about what the knob does- likely due to poor naming on my part- to the tune
of "well, it sounds like it should speed things up" (mentioned by multiple
people).
To compound this, I have no intention of maintaining a second regex
implementation. If someone would like to step up and volunteer to maintain a
lean-and-mean implementation for grep, this is OK, but we have very few
volunteers to maintain even our primary regex implementation.
This is better behavior than just silently doing the wrong thing. We do not
currently have plans to support -r/-R with the compression-enabled greps.

multiple connections that share a common log ID.
You can log connections in different modes. If you are doing a coordinated
test with a particular connection, you may tell the system to put it in
mode 4 (continuous dump). Or, if you just want to monitor for errors, you
can put it in mode 1 (ring buffer) and dump all the ring buffers associated

ID. You can set a default mode that will be applied to a particular ratio

Plan A mmap()'s the entire input file and operates on it in memory. The

This was clearly intentional to match "the behavior of the original code",
but it creates a discrepancy between Plan A and Plan B that doesn't seem
sensible and it's not inherently wrong to allow a NUL byte.
This change was motivated by the gemspec in net/rubygem-grpc failing to
patch, despite the patch being generated with diff, because a NUL byte was
used as a delimiter in the header briefly in an otherwise text file.
An alternative was considered: to fallback to plan B if plan A won't process
the entire file due to a NUL byte, but I deemed this to be the better option
since plan A isn't failing due to memory limitations and will fail later on
if it's really dealing with a file it shouldn't be.

The system call convention is different from i386 binaries running on
FreeBSD/amd64, but this is not noticeable by executables. On
FreeBSD/amd64, the vDSO already does padding of arguments and return
values to 64-bit values. On i386, it does not, meaning that system call
return values are simply stored in registers.
This change copies the existing amd64_cloudabi64.c to amd64_cloudabi32.c
and reimplements the functions for fetching system call arguments and
return values to use the same scheme as used by the vDSO that is used
when running cloudabi32 executables.
As arguments are automatically padded to 64-bit words by the vDSO in

The existing line count optimization was not used if the input was the
implicit stdin. Additionally, it wasn't used if only byte counting was
requested. This change expands the fast path to both of these scenarios.

Inputting fractional non-decimal numbers has never worked correctly in our
OpenBSD-derived dc(1). It truncates the input to a number of decimal places
equal to the number of hexadecimal (or whatever base) places given on the
input. That's unacceptable, because many numbers require more precision to
represent in base 10 than in their original bases.
Fix this bug by using as many decimal places as needed to represent the
input, up to the maximum of the global scale factor.
This has one mildly surprising side effect: the scale of a number entered in
non-decimal mode will no longer necessarily equal the number of hexadecimal
(or whatever base) places given on the input. I think that's an acceptable
behavior change, given that inputting fractional non-decimal numbers never
worked in the first place, and the man page doesn't specify whether trailing
zeros on the input should affect a number's scale.

sponge(1) is a utility that reads input until
complete, then opens the output file, then
writes to it. This makes it useful in pipelines
that read and write to the same file.

In case we are trying to read a catpage, the manpage variable is not defined.
It results in the "cattool" having no arguments.
In case the catpage is compressed, the cattool used is "zcat" which dies if the
standard input is a terminal, meaning the function calling it is exiting as if
there were no ".so"
In case the catpage is uncompressed, the cattool used is "zcat -f" which waits
reading standard input, making the man(1) command hang.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.
- Add a new KTR_STRUCT_ARRAY ktrace record type which dumps an array of
structures.
The structure name in the record payload is preceded by a size_t
containing the size of the individual structures. Use this to
replace the previous code that dumped the kevent arrays dumped for
kevent(). kdump is now able to decode the kevent structures rather
than dumping their contents via a hexdump.
One change from before is that the 'changes' and 'events' arrays are
not marked with separate 'read' and 'write' annotations in kdump
output. Instead, the first array is the 'changes' array, and the
second array (only present if kevent doesn't fail with an error) is
the 'events' array. For kevent(), empty arrays are denoted by an
entry with an array containing zero entries rather than no record.
- Move kevent decoding tables from truss to libsysdecode.
This adds three new functions to decode members of struct kevent:
sysdecode_kevent_filter, sysdecode_kevent_flags, and
sysdecode_kevent_fflags.
kdump uses these helper functions to pretty-print kevent fields.
- Move structure definitions for freebsd11 and freebsd32 kevent
structures to <sys/event.h> so that they can be shared with userland.
The 32-bit structures are only exposed if _WANT_KEVENT32 is defined.
The freebsd11 structures are only exposed if _WANT_FREEBSD11_KEVENT is
defined. The 32-bit freebsd11 structure requires both.
- Decode freebsd11 kevent structures in truss for the compat11.kevent()
system call.
- Log 32-bit kevent structures via ktrace for 32-bit compat kevent()
system calls.
- While here, constify the 'void *data' argument to ktrstruct().

Patches with very little context (-U0 and -U1) could get misapplied if
the file to be patched changes and a hunk is no longer applicable. Matching
with fuzz would be attempted and default to a match when we unexpectedly ran
out of context.
This also affected patches with higher levels of context but had limited
actual context due to the hunk being located near the beginning/end of file.

Humour is a funny thing. What is funny to one person is not funny to all
