If Plack is running with several workers we must not use Cache::Memory
as L2 cache.
If a value is set from a worker, it will not be available from other
workers as the Cache::Memory instance is not shared (of course!)
Moreover we now have Koha::Cache::Memory::Lite that does the same job,
so we should not expect performance regressions by removing it.

We need to define several namespaces for our cache system.
For instance sysprefs, koha conf (koha-conf.xml) and unit tests
should be defined in a separate namespace.
This will permit to
- launch the tests without interfering with other cache values
- and flush the sysprefs cache without flushing all other values
To do so, we need to store different Koha::Cache objects at a package
level. That's why this patch adds a new Koha::Caches module.

Bug 16044 introduced two-level caching mechanism to Koha::Cache. By
default, get_from_cache() returns a deep copy of the data structures
stored in L1 cache (aka "safe mode"). For extremely big and/or complex
data structures (like MARC framework hash-of-hashes-of-hashes returned
by GetMarcStructure() ), deep-cloning is currently sub-optimal;
this patch addresses that particular issue. It also provides an
ability to intermix "safe" and "unsafe" cache feches, in such
way that they don't interfere with each other (i.e., eliminating
the risk involved with "unsafe" calls possibly compromising
further "safe" calls).
Test plan:
1) apply patch
2) flush L2 cache if necessary (restart memcached daemon)
3) profile GetMarcStructure() calls before / after patch, e.g. by
running some script which calls it often (like catalogue search
w/ XSLT processing turned on, etc.) - GetMarcStructure() should be
faster than before, in all possible circumstances (eg. 18 msec
per call -> 10 msec p/call)
4) after testing, before returning to the master branch, flush L2 cache
again (restart memcached daemon) - otherwise all system preferences
returned from L2 cache would be suffixed with '-CF0'

Koha::Cache package does not take into account that, when using
fastmmap caching variant, mmaped cache file created in /tmp
(typically: /tmp/sharefile-koha-koha), would only be further
accessible to the one given OS user - the one which created it.
In many Koha setups, in the circumstances when various system scripts
are executed by 2+ users with diffrent UIDs (like multi-tenant servers,
for example) this may cause many kinds of issues. Observable symptom
is usually the appearance of the below error when searching, or looking
at MARC Framework pages and a few other places:
Open of share file /tmp/sharefile-koha-koha failed: Permission denied
at /usr/lib/perl5/Cache/FastMmap.pm line 640.
This patch:
- disables initialisation of fastmmap caching subsystem unless it is
explicitly requested by the user (CACHING_SYSTEM=fastmmap)
- disables fastmmap cache usage for command line scripts
(i.e. when GATEWAY_INTERFACE environment variable is not defined)
- adds the database name, host name and an ID of the OS user to the
mmaped file name created in /tmp, to prevent various kinds of
unintentional conflicts and/or permission problems from happening
To test:
1) remove the /tmp/sharefile-koha-* file[s] (if any)
2) do something which would lead to its re-creation (e.g., performing
any search in OPAC should be sufficient to cause that)
3) observe that /tmp/sharefile-koha-koha got created
4) remove it
5) apply patch
6) redo step 2)
7) observe that aforementioned file is no longer created in /tmp
8) set CACHING_SYSTEM environment variable to 'fastmmap'
9) redo step 2), observe that /tmp/sharefile-koha-* file got created
and that it's name now contains hostname, database name and UID
10) ensure that everything still works like it should and that there
are no regressions of any kinds anywhere in the system ;)

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.

The 3 patches for bug 8089 have been reverted, because they break

A follow-up has been provided, but it does not solve the problem on my

After a discussion with jared, Dobrica should work on another patch, so
the best option is to revert.
1. Replace all instances of memoize_memcached with appropriate calls
into Koha::Cache:

* C4::Biblio::GetMarcStructure
* C4::Languages::getFrameworkLanguages
* C4::Languages::getAllLanguages
* C4::SQLHelper::GetPrimaryKeys
* C4::SQLHelper::_get_columns
2. Replace all references to memcached with the appropriate calls into

* have DEBUG env set to 1
* reach addbiblio page to test the patch in Biblio.pm, or setup more than 1
language
* you should see in the logs that you're reading and writing from cache
* run the test suite twice both with and without the following environment
