| 9e7973fa | 3 | # This file specifies an array-of-hashes that define snippets of code that |
| 24fb648d DM |
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 | # | |
| 9e7973fa DM |
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 | # | |
| 24fb648d DM |
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 | # | |
| 9e7973fa DM |
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 | # loop:: structural code like for, while(), etc | |
| 37 | # regex:: regular expressions | |
| 38 | # string:: string handling | |
| 24fb648d | 39 | # |
| 9e7973fa DM |
40 | # |
| 41 | # Each hash has three fields: | |
| 24fb648d DM |
42 | # |
| 43 | # desc is a description of the test | |
| 44 | # setup is a string containing setup code | |
| 45 | # code is a string containing the code to run in a loop | |
| 46 | # | |
| 47 | # So typically a benchmark tool might do something like | |
| 48 | # | |
| 49 | # eval "package $token; $setup; for (1..1000000) { $code }" | |
| 9e7973fa DM |
50 | # |
| 51 | # Currently the only tool that uses this file is Porting/bench.pl; | |
| 52 | # try C<perl Porting/bench.pl --help> for more info | |
