2cae4efa0a Bug 2176 (3/5): adding methods to manage message_queue, new advance_notices.pl, new C4::SMS module
I've added methods to to C4::Letters to manage the database table
message_queue. This will let us keep track of messages sent
via email, sms, and rss to patrons. That way, we can show the history,
deal with failures, and reconstruct an RSS feed when needed.

misc/cronjobs/overduenotics.pl has been added. It prepares advance notices
and item due notices and stages messages to be sent in the message_queue
table.

C4::Overdues::Getoverdues now takes two optional arguments to tell it how
old of overdues to fetch.

Also, a C4::Circualtion::getUpcomingDueIssues method was added that
advance_notices.pl uses.

misc/cronjobs/process_message_queue.pl has been added. It sends the email
or SMS messages out of the message queue.

The C4::SMS module didn't work at all, and it has been rebuilt to use
an external perl module from CPAN, SMS::Send.

95889857c7 bug 2000 - add C4::Circulation::GetBranchBorrowerCircRule
This routine retrieves the branch/patron category circulation
rules for a given branch and patron category.  The return
value is a hashref containing the following key:

maxissueqty - maximum number of loans across all item types

This will first check for a specific branch and
category match from branch_borrower_circ_rules.

If no rule is found, it will then check default_branch_circ_rules
(same branch, default category).  If no rule is found,
it will then check default_borrower_circ_rules (default
branch, same category), then failing that, default_circ_rules
(default branch, default category).

If no rule has been found in the database, it will default to
the built in rule:

maxissueqty - undef

f36b8fd59a Commented out fixaccounts (not used anywhere). Also improved getnextacctno.
You can test getnextacctno like:
	perl -e 'use C4::Accounts; print getnextacctno(33), "\n";'
where 33 is a borrowernumber out of the accountlines table.  Get that number like:
	mysql> select borrowernumber,accountno from accountlines LIMIT 100;

8645d38f41 test suite: allow skipping of expensive tests
Defined a function attribute for KohaTest and subclasses
called 'Expensive'.  When a test method has that attribute,
it is skipped unless the RUN_EXPENSIVE_TESTS environment
variable is true.

To mark a test method, expensive, do this:

sub test_foo : Tests(4) Expensive { ... }

To mark a whole class and its subclasses expensive,
define a SKIP_CLASS sub (with empty body) with the
Expensive attribute:

sub SKIP_CLASS : Expensive { }

Updated the t/Makefile so that 'make test' runs
nonexpensive tests, while 'make fulltest' runs both
cheap and expensive tests.

Marked KohaTest::Installer test class expensive.

496b6c8ef4 bugfix - fix 'not' operator in NoZebra
Corrected bug that prevented the 'not' operator
from working consistently - i.e., a search of
'mice not men' would not always work.

Also added test cases for NoZebra, so far focusing on
NZanalyse and adding and deleting bibs.  A couple of
the test cases are currently known to fail and
therefore are marked TODO.  The tests in question
are to verify that rows in nozebra are removed if
no bib is linked to the relevant word.  However, it
looks like such rows are retained, just with
nozebra.biblionubmers set to ''.  Is there any
reason to keep these rows?

db755a4307 bug 2088: test suite refactoring to deal with t/override_context_prefs.pm
Some minor changes to get the test suite working a bit better:
I removed a superfluous method from t/lib/KohaTest.pm.
I made each barcode for the items added in KohaTest.pm unique so that they would actually get inserted.

Then, I removed t/override_context_prefs.pm. If you need that functionality, you're a database
dependent test and should be a module in t/lib.
So, I deleted all of the trivial .t tests that just 'use'd their modules and had no other
tests and replaced them with lib/KohaTest/*pm modules that do a little bit more checking
on those modules.
I removed the references to override_context_prefs.pm in all of the other .t modules.
They all pass now with no override_context_prefs.pm module.

The database_depenedent.pl test script still does not pass entirely. There's a problem with the zebra index
not being reset each time that the tables are truncated. I'll get to that.

no functional or documentation changes here.

22aa16e87f kohabug 2076 - remove three tables (DB rev 077)
Removed the categorytable, mediatypetable, and subcategorytable
tables.  These three tables appear to be from an incomplete
patch from pre-git that defined these tables to implement
additional search limits, and are not present in the 2.2.9
package.  In 3.0, these tables did nothing - the only code that
referred to them are incomplete admin editors that lack HTML
templates and are not referred to anywhere.

The updatedatabase.pl logic to remove these tables is conservative;
the tables are dropped only if they exist and are all empty.  Effectively,
this means that they'll be dropped if you've been running a fresh install
of 3.0 from git or the alphas or betas; if you've upgraded your database
from 2.2.9, these tables likely weren't in your database to begin with.

438ed23337 staging import - enhance record overlay behavior
Enhanced the ability of catalogers to specify how
bib and item records should be added, replaced, or
ignored during a staging import.

When an import batch of bib records is staged and commit,
the user can now explicitly specify what should occur
when an incoming bib record has, or does not have, a match
with a record already in the database.  The options are:

if match found (overlay_action):
  create_new (just add the incoming record)
  replace (replace the matched record with the incoming one)
  use_template (option not implemented)
  ignore (do nothing with the incoming bib; however, the
          items attached to it may still be processed
           based on the item action)

if no match is found (nomatch_action):
  create_new (just add the incoming record)
  ignore (do nothing with the incoming bib; in this
          case, any items attached to it will be
          ignored since there will be nothing to
          attach them to)

The following options for handling items embedded in the
bib record are now available:

  always_add (add the items to the new or replaced bib)
  add_only_if_match (add the items only if the incoming bib
                     matches an existing bib)
  add_only_if_add (add the items only if the incoming bib
                   does *not* match an existing bib)
  ignore (ignore the items entirely)

With these changes, it is now possible to support the following use cases:

[1] A library joining an existing Koha database wishes to add their
    items to existing bib records if they match, but does not want
    to overlay the bib records themselves.
[2] A library wants to load a file of records, but only handle
    the new ones, not ones that are already in the database.
[3] A library wants to load a file of records, but only
    handle the ones that match existing records (e.g., if
    the records are coming back from an authority control vendor).

Documentation changes:

* See description above; also, screenshots of the 'stage MARC records
for import' and 'manage staged MARC records' should be updated.

Test cases:

* Added test cases to exercise staging and committing import batches.

UI changes:

* The pages for staging and managing import batches now have
  controls for setting the overlay action, action if no match,
  and item action separately.
* in the manage import batch tool, user is notified when they
  change overlay action, no-match action, and item action
* HTML for manage import batch tool now uses fieldsets

Database changes (DB rev 076):

* added import_batches.item_action
* added import_batches.nomatch_action
* added 'ignore' as a valid value for import_batches.overlay_action
* added 'ignored' as a valid value for import_records.status
* added 'status' as a valid value for import_items.status

API changes:

* new accessor routines for C4::ImportBatch

    GetImportBatchNoMatchAction
    SetImportBatchNoMatchAction
    GetImportBatchItemAction
    SetImportBatchItemAction

* new internal functions for C4::ImportBatch to
  determine how a given bib and item are to be
  processed, based on overlay_action, nomatch_action,
  and item_action:

    _get_commit_action
    _get_revert_action

aad276c3cd test framework - two improvements
[1] When running the database-dependent tests (cd t, make test),
    all tables in the test database are dropped prior to running
    the installer and test cases.  This means that the test
    database will start with a clean slate.
[2] It is now possible to specify a single test class to run,
    to avoid having to run all of them:

    cd t
    make test TEST_CLASS=Search

    To run all DB-dependent tests, just do the usual

    cd t

c41da00b4a Bug 2044: allowing multiuple icon sets
I've rearranged the two directories where media type icons live.
I've also added two more collections of icons, one from
http://apps.carleton.edu/campus/library/bridge_icons/
and one from liblime (Tina). The first has a license restriction that I added
to the "Licenses" tab on the "About" page.

Then, I've adjusted the Item Types Administration page so that it can deal
with multiple collections of icons.

I also added a test script to verify that the two identical icon directories
are actually identical.

DOCUMENTATION CHANGE: It's possible that we need to add something to the administration
documentation to indicate how you can add more sets of icons if you want. You simply add
directory to koha-tmpl/intranet-tmpl/prog/img/itemtypeimg/ and to
koha-tmpl/opac-tmpl/prog/itemtypeimg. The icons should start showing up.

80568463ea improvements to automated tests, including a testing database
I'm adding a bunch of additions to the test suite. There is now a test
database that is created, and a test instance of the zebra server and
daemon that are run before the tests in t/database-dependent.pl are
run. This means that you can test things that insert (or destroy)
things in the database.

To use these tests, after you 'make' your koha installation, you can
change to the 't' directory and 'make test' there.

There is now an additional question asked during installation. It asks
whether you would like to run the data-dependent tests. If so, It asks
you for some login information to a test database. I recommend that
you do not not use your production database here. It will delete all
of the data in it.

Things that need improvement:
* I suspect that there are large parts that are not very platform
  independent, so they will need to be improved.
* There are some parts of the installer that will probably be
  refactored to let this work a little bit better, including being run
  directly from a main-level 'make' target at some point.
* Lots more tests to add. Be bold! (see the t/lib directory)
* other tests in t/*.t can possibly benefit from being included in here.

There are two required perl modules for this part of the test suite. I
use:
'Test::Class' => 0.028,
'Test::Class::Load' => 0.02,
They are not listed as requirements in the top-level Makefile.PL
because they're not actually required to install or use Koha, but if
you want to run the test suite, you can install them from CPAN.

60a98d258a IMPORTANT - refactor MARC character set handling
* IsStringUTF8ish - determine if scalar contains a string in UTF8
* MarcToUTF8Record - convert MARC blob or MARC::Record to UTF8
* SetMarcUnicodeFlag - set appropriate MARC21 or UNIMARC field to
  indicate that record is in UTF-8.

Design points of this module include:

* No dependencies on other C4 modules, making it easier to add
  more test cases
* All character conversion code in one place
* Single entry point for doing a character conversion on a
  MARC record
* Capture of errors and warnings produced by Text::Iconv
  and MARC::Charset
* Start of support for guessing the source character set of
  a MARC record.

Several functions were moved from other scripts
or modules to C4::Charset:

* C4::Koha->FixEncoding (expanded and renamed
  MarcToUTF8Record)
* C4::Koha->char_decode5426
* fMARC8ToUTF8 from bulkmarcimport.pl (renamed
  _marc_marc8_to_utf8)

Several batch jobs were adjusted to use MarcToUTF8Record instead of
FixEncoding.

5290ec5596 test suite cleanup
Many of the tests were failing or putting warnings
because a valid systempreferences table is
usaully absent by the time 'make test' is run.

Fortunately, only a few modules try to invoke
C4::Context->preference during module initialization,
so added to the test suite override_context_prefs.pm,
which replaces preference() with a sub to return
testing values for three variables: 'dateformat',
'marcflavour', and 'LibraryName'.

Also fixed bug in t/Boolean.t
