test: Optimize operator lookup.

2016-01-30T19:59:58+00:00

The linear search using strcmp() shows up in pmcstat for several percent.

Split the operators into lengths and whether they start with '-' and compare
bytes using == instead of strcmp().

A simple test

sh -c 'i=0; w=$(printf %0100d 7); while [ "$i" -lt 1000000 ]; do
    v=$(printf %sx%s "$w" "$w"); i=$((i+1)); done'

is over 4% faster on an amd64 bhyve VM.

test: Avoid looking up again the type of a known binary operator.

test: Simplify the code by unifying op_num and op_type.

2013-12-01T17:00:57+00:00

The global variable t_wp_op is no longer needed.

test: Remove -ntXY and -otXY primaries.

This reverts commit r247274.

As maintainer of sh, I disapprove of this feature addition.

It is too specific and can be done without easily using find(1) or stat(1).
I will add some hints to the test(1) man page shortly.

In general, FreeBSD sh is not the place to invent new shell language
features. This is how it has been maintained and adding features randomly
does not work with that.

The new syntax (e.g. [ FILE1 -ntca FILE2 ]) looks cryptic to me.

Enhance test(1) by adding provision to compare any combination of the

access, birth, change and modify times of two files, instead of only
being able to compare modify times.  The builtin test in sh(1) will
automagically acquire the same expansion.

test: Reduce code size of ops table.

Put some static keywords in the source code.

2011-10-31T08:59:17+00:00

For these simple utilities, it doesn't harm to make all global variables
static. In fact, this allows the compiler to perform better forms of
optimisation and analysis.

bin: Prefer strrchr() to rindex().

2011-03-15T22:22:11+00:00

This removes the last index/rindex usage from /bin.

Accept == as an alias of = which is a popular GNU extension.

2011-02-27T12:28:06+00:00

This is intentionally undocumented for now since it's not part
of any standard.
