Jeff King 2d86a96220 t: avoid sed-based chain-linting in some expensive cases
Commit 878f988350 (t/test-lib: teach --chain-lint to detect broken
&&-chains in subshells, 2018-07-11) introduced additional chain-lint
tests which add an extra "sed" pipeline to each test we run. This has a
measurable impact on runtime. Here are timings with and without a new
environment variable (added by this patch) that lets you disable just
the additional sed-based chain-lint tests:

  Benchmark #1: GIT_TEST_CHAIN_LINT_HARDER=1 make test
    Time (mean ± σ):     64.202 s ±  1.030 s    [User: 622.469 s, System: 301.402 s]
    Range (min … max):   61.571 s … 65.662 s    10 runs

  Benchmark #2: GIT_TEST_CHAIN_LINT_HARDER=0 make test
    Time (mean ± σ):     57.591 s ±  0.333 s    [User: 529.368 s, System: 270.618 s]
    Range (min … max):   57.143 s … 58.309 s    10 runs

  Summary
    'GIT_TEST_CHAIN_LINT_HARDER=0 make test' ran
      1.11 ± 0.02 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=1 make test'

Of course those extra lint checks are doing something useful, so paying
a few extra seconds (at least on Linux) isn't so bad (though note the
CPU time; we're bounded in our parallel run here by the slowest test, so
it really is ~120s of CPU improvement).

But we can observe that there are some test scripts where they produce a
much stronger effect, and provide less value. In t0027 and t3070 we run
a very large number of small tests, all driven by a series of
functions/loops which are filling in the test bodies. There we get much
less bang for our buck in terms of bug-finding versus CPU cost.

This patch introduces a mechanism for controlling when those extra
lint checks are run, at two levels:

  - a user can ask to disable or to force-enable the checks by setting
    GIT_TEST_CHAIN_LINT_HARDER

  - if the user hasn't specified a preference, individual scripts can
    disable the checks by setting GIT_TEST_CHAIN_LINT_HARDER_DEFAULT;
    scripts which don't set that get the current behavior of enabling
    them.

In addition, this patch flips the default for t0027 and t3070's
mass-generated sections to disable the extra checks. Here are the timing
results for t0027:

  Benchmark #1: GIT_TEST_CHAIN_LINT_HARDER=1 ./t0027-auto-crlf.sh
    Time (mean ± σ):     17.078 s ±  0.848 s    [User: 14.878 s, System: 7.075 s]
    Range (min … max):   15.952 s … 18.421 s    10 runs

  Benchmark #2: GIT_TEST_CHAIN_LINT_HARDER=0 ./t0027-auto-crlf.sh
    Time (mean ± σ):      9.063 s ±  0.759 s    [User: 7.890 s, System: 3.362 s]
    Range (min … max):    7.747 s … 10.619 s    10 runs

  Benchmark #3: ./t0027-auto-crlf.sh
    Time (mean ± σ):      9.186 s ±  0.881 s    [User: 7.957 s, System: 3.427 s]
    Range (min … max):    7.796 s … 10.498 s    10 runs

  Summary
    'GIT_TEST_CHAIN_LINT_HARDER=0 ./t0027-auto-crlf.sh' ran
      1.01 ± 0.13 times faster than './t0027-auto-crlf.sh'
      1.88 ± 0.18 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=1 ./t0027-auto-crlf.sh'

We can see that disabling the checks for the whole script buys us an
almost 2x speedup. But the new default behavior, disabling them only for
the mass-generated part, gets us most of that speedup (but still leaves
the checks on for further manual tests people might write).

  As a side note, I'd caution about comparing runtimes and CPU seconds
  between this timing and the earlier "make test" one. In "make test",
  we're running a lot of scripts in parallel, so the CPU is throttling
  down (and thus a CPU second saved here would count for more during a
  parallel run; the same work takes more CPU seconds there).

We get similar results for t3070:

  Benchmark #1: GIT_TEST_CHAIN_LINT_HARDER=1 ./t3070-wildmatch.sh
    Time (mean ± σ):     20.054 s ±  3.967 s    [User: 16.003 s, System: 8.286 s]
    Range (min … max):   11.891 s … 23.671 s    10 runs

  Benchmark #2: GIT_TEST_CHAIN_LINT_HARDER=0 ./t3070-wildmatch.sh
    Time (mean ± σ):     12.399 s ±  2.256 s    [User: 7.542 s, System: 5.342 s]
    Range (min … max):    9.606 s … 15.727 s    10 runs

  Benchmark #3: ./t3070-wildmatch.sh
    Time (mean ± σ):     10.726 s ±  3.476 s    [User: 6.790 s, System: 4.365 s]
    Range (min … max):    5.444 s … 15.376 s    10 runs

  Summary
    './t3070-wildmatch.sh' ran
      1.16 ± 0.43 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=0 ./t3070-wildmatch.sh'
      1.87 ± 0.71 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=1 ./t3070-wildmatch.sh'

Again, we get almost a 2x speedup disabling these. In this case, there
are no tests not covered by the script's "default to disable" behavior,
so the second two benchmarks should be the same (and while they do
differ, you can see the variance is quite high but they're within one
standard deviation).

So it seems like for these two scripts, at least, disabling the extra
checks is a reasonable tradeoff. Sadly, the overall runtime of "make
test" on my system doesn't get much faster. But that's because we're
mostly limited by the cost of the single biggest test. Here are the
top-5 tests by wall-clock time from a parallel run, before my patch:

  57.9192368984222 t9001-send-email.sh
  45.6329638957977 t0027-auto-crlf.sh
  32.5278220176697 t3070-wildmatch.sh
  22.2701289653778 t7610-mergetool.sh
  20.8635759353638 t1701-racy-split-index.sh

And after:

  57.1476998329163 t9001-send-email.sh
  33.776211977005 t0027-auto-crlf.sh
  21.3116669654846 t7610-mergetool.sh
  20.7748689651489 t1701-racy-split-index.sh
  19.6957249641418 t7112-reset-submodule.sh

We dropped 12s from t0027, and t3070 dropped off our list entirely at
around 16s. In both cases we're bound by t9001, but its slowness is
due to the actual tests, so we'll have to deal with it in a different
way. But this reduces overall CPU, and means that dealing with t9001 (by
improving the speed of send-email or splitting it apart) will let us
reduce our overall runtime even on multi-core machines.
