Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

Apache::Test - wrapper with helpers for testing Apache
use Apache::Test;
Apache::Test is a wrapper around the standard "" with helpers for testing an Apache server.
plan This function is a wrapper around "Test::plan": plan tests => 3; just like using, plan 3 tests. If the first argument is an object, such as an "Apache::RequestRec" object, "STDOUT" will be tied to it. The "" global state will also be refreshed by calling "Apache::Test::test_pm_refresh". For example: plan $r, tests => 7; ties STDOUT to the request object $r. If there is a last argument that doesn't belong to "Test::plan" (which expects a balanced hash), it's used to decide whether to con- tinue with the test or to skip it all-together. This last argument can be: o a "SCALAR" the test is skipped if the scalar has a false value. For example: plan tests => 5, 0; But this won't hint the reason for skipping therefore it's better to use have(): plan tests => 5, have 'LWP', { "perl >= 5.7.3 is required" => sub { $] >= 5.007003 } }; see have() for more info. o an "ARRAY" reference have_module() is called for each value in this array. The test is skipped if have_module() returns false (which happens when at least one C or Perl module from the list cannot be found). o a "CODE" reference the tests will be skipped if the function returns a false value. For example: plan tests => 5, \&have_lwp; the test will be skipped if LWP is not available All other arguments are passed through to Test::plan as is. ok Same as Test::ok, see documentation. sok Allows to skip a sub-test, controlled from the command line. The argument to sok() is a CODE reference or a BLOCK whose return value will be passed to ok(). By default behaves like ok(). If all sub-tests of the same test are written using sok(), and a test is executed as: % ./t/TEST -v skip_subtest 1 3 only sub-tests 1 and 3 will be run, the rest will be skipped. skip Same as Test::skip, see documentation. test_pm_refresh Normally called by Apache::Test::plan, this function will refresh the global state maintained by, allowing "plan" and friends to be called more than once per-process. This function is not exported. Functions that can be used as a last argument to the extended plan(): plan tests => 5, &have_http11; Require HTTP/1.1 support. have_ssl plan tests => 5, &have_ssl; Require SSL support. Not exported by default. have_lwp plan tests => 5, &have_lwp; Require LWP support. have_cgi plan tests => 5, &have_cgi; Requires mod_cgi or mod_cgid to be installed. have_apache plan tests => 5, have_apache 2; Requires httpd-2.x (apache-2.x). plan tests => 5, have_apache 1; Requires apache-1.3.x. have_perl plan tests => 5, have_perl 'iolayers'; plan tests => 5, have_perl 'ithreads'; Requires a perl extension to be present, or perl compiled with certain capabilities. The first example tests whether "PerlIO" is available, the second whether: $Config{useithread} eq 'define'; have_module plan tests => 5, have_module 'CGI'; plan tests => 5, have_module qw(CGI Find::File); plan tests => 5, have_module ['CGI', 'Find::File', 'cgid']; Requires Apache C and Perl modules. The function accept a list of arguments or a reference to a list. In case of C modules, depending on how the module name was passed it may pass through the following completions: 1 have_module 'proxy_http.c' If there is the .c extension, the module name will be looked up as is, i.e. 'proxy_http.c'. 2 have_module 'mod_cgi' The .c extension will be appended before the lookup, turning it into 'mod_cgi.c'. 3 have_module 'cgi' The .c extension and mod_ prefix will be added before the lookup, turning it into 'mod_cgi.c'. have plan tests => 5, have 'LWP', { "perl >= 5.7.3 is required" => sub { $] >= 5.007003 } }, { "not Win32" => sub { $^O eq 'MSWin32' } }, 'cgid'; have() is more generic function which can impose multiple requirements at once. All requirements must be satisfied. have()'s argument is a list of things to test. The list can include scalars, which are passed to have_module(), and hash references. The hash references have a condition code reference as a value and a reason for failure as a key. The condition code is run and if it fails the provided reason is used to tell user why the test was skipped. In the presented example, we require the presense of the "LWP" Perl module, "mod_cgid", that we run under perl >= 5.7.3 on Win32. It's possible to put more than one requirement into a single hash reference, but be careful that the keys will be different: have 'LWP', { "perl >= 5.7.3 is required" => sub { $] >= 5.007003 }, "not Win32" => sub { $^O eq 'MSWin32' }, }, 'cgid'; Also see plan(). Apache::TestToString Class The Apache::TestToString class is used to capture output into a string. Example: Apache::TestToString->start; plan tests => 4; ok $data eq 'foo'; ... # $tests will contain the output: 1..4\nok 1\n... my $tests = Apache::TestToString->finish; perl v5.8.0 2002-09-10 Apache::Test(3)
