This filter which check validity of EAN-13 barcode and padd it with zeros
up to full 13 digit number. This will also expand 12 digit UPC-A barcodes
to EAN-13 automatically which is useful for older barcode readers which tend
to ignore first zero in EAN-13 if they have just UPC-A support.
It should be noted that EAN-13 or UPC-A product codes printed on books are not
good choice for barcodes in Koha since each item has to have unique barcode.
Test scenario:
1. prove t/Circulation_barcodedecode.t
this checks expansion of 12 digit UPC-A to 13 digit EAN-13 and zero padding
2. in systempreferences search for itemBarcodeInputFilter and select EAN-13
3. edit one item and assign it valid EAN-13 barcode, eg. 0000000695152, check it out
4. test checkin with just 695152 to test leading zero expansion

In India a ILS product called Libsuite8 prints barcodes like b0007432. The barcode is not stored anywhere in libsuite8's database. Neither is barcode available in any of the reports generated by the software.
The barcode 'b0007432' when scanned into the libsuite8 software is de-constructed like 'b' which is the itemtype i.e. Book in this instance, and '7432' which is the 'Accession Number'. The software then takes the logged in staff's branchcode and does a join on three tables 'Location', 'Media_Type', and 'Books' to retrieve the particular record from the database.
There is no possibility of recreating the barcodes for insertion in Koha while doing a retrospective conversion, because of arbitrary length of the barcode string AND arbitrary number of zeros in the numeric part of the printed barcode AND the fact that there are no reports available from the software which contain barcodes AND the fact that the barcode is not stored in the database.
But most importantly due to the simple fact that printed barcodes are duplicated among branches.
Therefore this patch emulates the functionality of Libsuite8 software of converting the scanned barcode into one stored in Koha using the itemBarcodeInputFilter system preference.
To use this new itemBarcodeInputFilter systempreference choice called 'libsuite8', the barcodes stored in Koha must match the pattern of <branchcode>-<itemtype_code>-<accession_number>. This is easy to achieve while doing retrospective conversion from Libsuite8 to Koha.
As expected the itemBarcodeInputFilter will return unmodified barcode if presented with a barcode of pattern <branchcode>-<itemtype_code>-<accession_number>
This revision corrects the way updatedatabase.pl is changed in order to correctly update version and insert the libsuite8 option in the database. Also kohaversion.pl is changed in the recommended format of 3.0X.0X.XXX to reflect database has changed.
This revision also changes the erronorous itemBarcodeInputFilter description in koha-tmpl/intranet-tmpl/prog/en/modules/admin/preferences/circulation.pref from 'scanned patron barcodes' to 'scanned item barcodes' there by eliminating need for a separate patch for bug 5417.

1) applied patch to HEAD
2) set next database number in kohaversion.pl and updatedatabase.pl
3) webinstaller kicked in, update ok
4) typed the barcodes from test cases into check-in
Barcodes used my local branch code, everything seemed ok to me.

This patch amends the function to return barcode, in particular when
filter is not defined. It also adds an optional 2nd argument to
allow the filter to be specified by caller, enabling testing.
Non-DB-dependent test script included. Note: T-prefix style
barcode filter is not documented, and drops the first nonzero
digit after the T. This seems mistaken, but is not corrected here
to avoid any surprises.
