| 3 | # This file specifies an array-of-hashes that define snippets of code that |
| 4 | # can be run by various measurement and profiling tools. |
| 5 | # |
| 6 | # The basic idea is that any time you add an optimisation that is intended |
| 7 | # to make a particular construct faster, then you should add that construct |
| 8 | # to this file. |
| 9 | # |
| 10 | # Under the normal test suite, the test file benchmarks.t does a basic |
| 11 | # compile and run of each of these snippets; not to test performance, |
| 12 | # but just to ensure that the code doesn't have errors. |
| 13 | # |
| 14 | # Over time, it is intended that various measurement and profiling tools |
| 15 | # will be written that can run selected (or all) snippets in various |
| 16 | # environments. These will not be run as part of a normal test suite run. |
| 17 | # |
| 18 | # It is intended that the tests in this file will be lightweight; e.g. |
| 19 | # a hash access, an empty function call, or a single regex match etc. |
| 20 | # |
| 21 | # This file is designed to be read in by 'do' (and in such a way that |
| 22 | # multiple versions of this file from different releases can be read in |
| 23 | # by a single process). |
| 24 | # |
| 25 | # The top-level array has name/hash pairs (we use an array rather than a |
| 26 | # hash so that duplicate keys can be spotted) Each name is a token that |
| 27 | # describes a particular test. Code will be compiled in the package named |
| 28 | # after the token, so it should match /^(\w|::)+$/a. It is intended that |
| 29 | # this can be used on the command line of tools to select particular |
| 30 | # tests. |
| 31 | # In addition, the package names are arranged into an informal hierarchy |
| 32 | # whose top members are (this is subject to change): |
| 33 | # |
| 34 | # call:: subroutine and method handling |
| 35 | # expr:: expressions: e.g. $x=1, $foo{bar}[0] |
| 36 | # func:: perl functions, e.g. func::sort::... |
| 37 | # loop:: structural code like for, while(), etc |
| 38 | # regex:: regular expressions |
| 39 | # string:: string handling |
| 40 | # |
| 41 | # |
| 42 | # Each hash has up to five fields: |
| 43 | # |
| 44 | # desc is a description of the test; if not present, it defaults |
| 45 | # to the same value as the 'code' field |
| 46 | # |
| 47 | # setup is an optional string containing setup code that is run once |
| 48 | # |
| 49 | # code is a string containing the code to run in a loop |
| 50 | # |
| 51 | # pre is an optional string containing setup code which is executed |
| 52 | # just before 'code' for every iteration, but whose execution |
| 53 | # time is not included in the result |
| 54 | # |
| 55 | # post like pre, but executed just after 'code'. |
| 56 | # |
| 57 | # So typically a benchmark tool might execute variations on something like |
| 58 | # |
| 59 | # eval "package $name; $setup; for (1..1000000) { $pre; $code; $post }" |
| 60 | # |
| 61 | # Currently the only tool that uses this file is Porting/bench.pl; |
| 62 | # try C<perl Porting/bench.pl --help> for more info |
| 63 | # |
| 64 | # ------ |
| 65 | # |
| 66 | # Note: for the cachegrind variant, an entry like |
| 67 | # 'foo::bar' => { |
| 68 | # setup => 'SETUP', |
| 69 | # pre => 'PRE', |
| 70 | # code => 'CODE', |
| 71 | # post => 'POST', |
| 72 | # } |
| 73 | # creates two temporary perl sources looking like: |
| 74 | # |
| 75 | # package foo::bar; |
| 76 | # BEGIN { srand(0) } |
| 77 | # SETUP; |
| 78 | # for my $__loop__ (1..$ARGV[0]) { |
| 79 | # PRE; 1; POST; |
| 80 | # } |
| 81 | # |
| 82 | # and as above, but with the loop body replaced with: |
| 83 | # |
| 84 | # PRE; CODE; POST; |
| 85 | # |
| 86 | # It then pipes each of the two sources into |
| 87 | # |
| 88 | # PERL_HASH_SEED=0 valgrind [options] someperl [options] - N |
| 89 | # |
| 90 | # where N is set to 10 and then 20. |
| 91 | # |
| 92 | # It then uses the result of those four cachegrind runs to subtract out |
| 93 | # the perl startup and loop overheads (including SETUP, PRE and POST), leaving |
| 94 | # (in theory only CODE); |
| 95 | # |
| 96 | # Note that misleading results may be obtained if each iteration is |
| 97 | # not identical. For example with |
| 98 | # |
| 99 | # code => '$x .= "foo"', |
| 100 | # |
| 101 | # the string $x gets longer on each iteration. Similarly, a hash might be |
| 102 | # empty on the first iteration, but have entries on subsequent iterations. |
| 103 | # |
| 104 | # To avoid this, use 'pre' or 'post', e.g. |
| 105 | # |
| 106 | # pre => '$x = ""', |
| 107 | # code => '$x .= "foo"', |
| 108 | # |
| 109 | # Finally, the optional 'compile' key causes the code body to be wrapped |
| 110 | # in eval qw{ sub { ... }}, so that compile time rather than execution |
| 111 | # time is measured. |
