To test:
- Apply first 2 patches for unit tests and changes to Services.pm
- Turn off mysql
- Run t/00-load.t
- Verify that the test fails.
- Apply this third patch.
- Run t/00-load.t again.
- Verify this time it passes.

Comment: Work well, no koha-qa errors.
Without third patch and mysql down, test fails,
with third patch it succeed.

At the moment we cache numerous pieces of information in module-level
variables which then do not get updated in other threads/processes when
they are changed by the user. This is a serious usability issue.
Examples of this include the way we treat sysprefs (there is now a
method to disable the syspref cache, but by default it is enabled),
notices, frameworks, field mappings, and koha-conf.xml, at least.
This patch sets the stage for eliminating this problem by making it
possible to convert module-level cache variables into variables that
are actually backed by whatever caching system may be configured. This
is done through a special Koha::Cache::Object class which can be tied
to the variables that are being used for caching and provided with a
constructor method/closure to allow the cache to be reloaded when it
expires. For example:
my $cache = Koha::Cache->new();
my $data = 'whatever';
my $variable = Koha::Cache->create_scalar(
{
'key' => 'whatever',
'timeout' => 2,
'constructor' => sub { return $data; },
}
);
print "$$variable\n"; # Prints "whatever"
The one change this necessitates for accessing the data is that the
variable must be dereferenced an additional time before use (i.e.
$$variable instead of $variable). There is no difference when the
variable tied is a hash (created with Koha::Cache->create_hash). This
is a small price to pay for Koha working in a multi-threaded, persistent
environment. This change will also make caching easier in general.
CHI was incompatible with the variable tying, so this patch also removes
the dependency on CHI, using instead Cache::Memcached::Fast,
Cache::FastMmap, and Cache::Memory, when they are available.
To test:
1) Apply patch.
2) Run unit test t/Cache.t (after setting the MEMCACHED_SERVERS and
CACHING_SYSTEM environment variables). As no changes were made to
the tests already in that file, this passing demonstrates there
are no regressions.
3) With memcached caching enabled (you must set the MEMCACHED_SERVERS
and CACHING_SYSTEM environment variables) and DEBUG turned on (i.e.
the DEBUG environment variable set to 1), try running a report via
the web service ([intranet]/cgi-bin/koha/svc/report?id=1 and check
your web server logs to confirm that there are messages like
"get_from_cache for intranet:report:id:1" in them.
4) If the reports worked, sign off.
NOTE: Technically you could test this without needing memcached by
installing libcache-fastmmap-perl and setting CACHING_SYSTEM to
'fastmmap' instead of 'memcached'. You could also install libcache-perl
and set CACHING_SYSTEM to 'memory' but there would be little point as
the cached variables would go out of scope in between runs.

Several patterns were being skipped unnecessarily in t/00-load.t:
* C4::Cache* - no longer exists
* C4::Record - no longer requires database
* C4::Serials - no longer requires database
To test:
1) Unset KOHA_CONF and/or shut down MySQL.
2) Run `prove t/00-load.t`
3) If the test passes, the patch is good.

Prior to this patch, t/00-load.t was trying to load Koha::SearchEngine,
which fails when Moose is not installed.

C4::Members::Statistics uses the database in its BEGIN {} block,
which breaks the package build process. This patch causes it to be
skipped in the 00-load test.

This moves the DB-requiring tests out of the way, with the exception of
00-load.t which is used by the git hooks. For it, it makes it skip
loading problematic modules. This allows 'make test' to complete successfully
without a database configured, wich is a required part of making packages.
This has been tested against the v3.02.03 tag and the master branch.
