NAME

Perl Core Smoke Test Suite

SYNOPSIS

  # at 22:25
  sh smoke.sh [~/perlsmoke/perl-current [smoke.cfg]]
  #

  or for the brave and trustworthy

  # perl Makefile.PL

DESCRIPTION

The perl core smoke test suite is a set of simple scripts that try to run the perl core tests on as many configurations as possible and combine that into a easy to parse report.

The perl source tree is refreshed using rsync to the latest level of the perl development branche before the smoke tests start. Note that rsync in the smoke uses --delete, which <b>removes</b> any existing files on that directory that are not part of the perl source tree.

INSTALLATION

Create an empty directory where the perl source tree is to be placed when smoking (e.g. ~/perlsmoke/perl-current).

Create or use a location to put the three scripts needed for the smoke (e.g. ~/perlsmoke/smoke), and put the files from the distribution there. Probably you already did so, because you are reading this file.

Edit smoke.sh and change the PC= definition to reflect the location you just chose in the first step of the initialisation. Theoretically you are now ready to go, just follow the SYNOPSIS to give it a first shot for tonight.

Optionally delete lines from config.sh (or a local copy with a different name) for which you are certain your system doesn't support it (like threading or 64bit configurations)

If something useful happens, do it every night using cron instead of at.

Win32 users

To make it clear, the perl core smoke suite treats cygwin as a unixy platform and not as true Win32.

We have tried to make this perl core smoke suite transparent for the use with various Win32 C-compilers (MSVC, BCC, GCC) and provided separate files for automation: smokew32.bat and smokew32.cfg please read those before you start.

To sync up with the current perl source-tree you'll need a working rsync (cygwin).

There is an issue with automatically sending the report to the daily-build mailinglist, wich we hope is resolved in the next version.

Slow Systems

It can happen that your system is not able to persue all the tests, either because it is too slow or because some of the configurations are not supported by the system. At first, don't worry, they are detected by the report creation script and shown as such.

After the first run gave you some idea of how long the smoke will run on your system, you can create your own copy of smoke.cfg where you either add new combinations and/or test levels, or delete lines to speed up the run time of smoke.

At the moment there are no guidelines of how to change the configuration best to fit the needs of perl5-porters while still getting as much smoke out of the test as possible, simply because the needs of perl5-porters change over time :)

If the test captures too many cycles of your CPU to continue production work, just kill the "mktest.pl" process and the report will be generated over the results captured untill then.

Misc

As always, have the appropriate amount of fun

TODO

Win32

Windows configurations are not as easy as Unix, but requires make fiddling. Windows2000 however supports long names and <i>might</i> just pick up the current way of going around without any hassle.

Initialisation and installation

Though I've tried to make Makefile.PL do what's neccasary, there's probably still some issues to be fixed for non-unix operating systems

Plan

At this date (early September 2002) my plan for Test::Smoke is:

  - This release (1.15) minor fixes
  - VERSION 1.20, a wrapper script for fetching source-tree etc
  - VERSION 2.00, an objectified version for easier code maintenance
