 129 =head1 NAME
 130
 131 C4::Circulation - Koha circulation module
 132
 133 =head1 SYNOPSIS
 134
 135 use C4::Circulation;
 136
 137 =head1 DESCRIPTION
 138
 139 The functions in this module deal with circulation, issues, and
 140 returns, as well as general information about the library.
 141 Also deals with stocktaking.
 142
 143 =head1 FUNCTIONS
 144
 145 =head2 barcodedecode
 146
 147   $str = &barcodedecode($barcode, [$filter]);
 148
 149 Generic filter function for barcode string.
 150 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 151 Will do some manipulation of the barcode for systems that deliver a barcode
 152 to circulation.pl that differs from the barcode stored for the item.
 153 For proper functioning of this filter, calling the function on the
 154 correct barcode string (items.barcode) should return an unaltered barcode.
 155
 156 The optional $filter argument is to allow for testing or explicit
 157 behavior that ignores the System Pref.  Valid values are the same as the
 158 System Pref options.

 249
 250 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 251
 252 C<$newbranch> is the code for the branch to which the item should be transferred.
 253
 254 C<$barcode> is the barcode of the item to be transferred.
 255
 256 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 257 Otherwise, if an item is reserved, the transfer fails.
 258
 259 Returns three values:
 260
 261 =over
 262
 263 =item $dotransfer
 264
 265 is true if the transfer was successful.
 266
 267 =item $messages
 268
 269 is a reference-to-hash which may have any of the following keys:
 270
 271 =over
 272
 273 =item C<BadBarcode>
 274
 275 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 276
 277 =item C<IsPermanent>
 278
 279 The item's home branch is permanent. This doesn't prevent the item from being transferred, though. The value is the code of the item's home branch.
 280
 281 =item C<DestinationEqualsHolding>
 282
 283 The item is already at the branch to which it is being transferred. The transfer is nonetheless considered to have failed. The value should be ignored.
 284
 285 =item C<WasReturned>
 286
 287 The item was on loan, and C<&transferbook> automatically returned it before transferring it. The value is the borrower number of the patron who had the item.
 288
 289 =item C<ResFound>
 290
 291 The item was reserved. The value is a reference-to-hash whose keys are fields from the reserves table of the Koha database, and C<biblioitemnumber>. It also has the key C<ResFound>, whose value is either C<Waiting> or C<Reserved>.
 292
 293 =item C<WasTransferred>
 294
 295 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1205
1206 Issue a book. Does no check, they are done in CanBookBeIssued. If we reach this sub, it means the user confirmed if needed.
1207
1208 =over 4
1209
1210 =item C<$borrower> is a hash with borrower informations (from GetMember or GetMemberDetails).
1211
1212 =item C<$barcode> is the barcode of the item being issued.
1213
1214 =item C<$datedue> is a DateTime object for the max date of return, i.e. the date due (optional).
1215 Calculated if empty.
1216
1217 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
1218
1219 =item C<$issuedate> is the date to issue the item in iso (YYYY-MM-DD) format (optional).
1220 Defaults to today.  Unlike C<$datedue>, NOT a DateTime object, unfortunately.
1221
1222 AddIssue does the following things :
1223
1224   - step 01: check that there is a borrowernumber & a barcode provided
1225   - check for RENEWAL (book issued & being issued to the same patron)
1226       - renewal YES = Calculate Charge & renew
1227       - renewal NO  =
1228           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
1229           * RESERVE PLACED ?
1230               - fill reserve if reserve to this patron
1231               - cancel reserve or not, otherwise
1232           * TRANSFERT PENDING ?
1233               - complete the transfert
1234           * ISSUE THE BOOK

1564 Retrieves circulation rule attributes that apply to the given

1566 The return value is a hashref containing the following key:
1567
1568 maxissueqty - maximum number of loans that a
1569 patron of the given category can have at the given
1570 branch.  If the value is undef, no limit.
1571
1572 maxonsiteissueqty - maximum of on-site checkouts that a
1573 patron of the given category can have at the given
1574 branch.  If the value is undef, no limit.
1575
1576 This will first check for a specific branch and
1577 category match from branch_borrower_circ_rules.
1578
1579 If no rule is found, it will then check default_branch_circ_rules
1580 (same branch, default category).  If no rule is found,
1581 it will then check default_borrower_circ_rules (default
1582 branch, same category), then failing that, default_circ_rules
1583 (default branch, default category).
1584
1585 If no rule has been found in the database, it will default to
1586 the buillt in rule:
1587
1588 maxissueqty - undef
1589 maxonsiteissueqty - undef

1591 C<$branchcode> and C<$categorycode> should contain the

2700 C<$borrowernumber> is the borrower number of the patron who currently
2701 has the item on loan.
2702
2703 C<$itemnumber> is the number of the item to renew.

2705 C<$override_limit>, if supplied with a true value, causes
2706 the limit on the number of times that the loan can be renewed
2707 (as controlled by the item type) to be ignored. Overriding also allows
2708 to renew sooner than "No renewal before" and to manually renew loans
2709 that are automatically renewed.
2710
2711 C<$CanBookBeRenewed> returns a true value if the item may be renewed. The
2712 item must currently be on loan to the specified borrower; renewals
2713 must be allowed for the item's type; and the borrower must not have
2714 already renewed the loan. $error will contain the reason the renewal can not proceed
