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

 251
 252 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 253
 254 C<$newbranch> is the code for the branch to which the item should be transferred.
 255
 256 C<$barcode> is the barcode of the item to be transferred.
 257
 258 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 259 Otherwise, if an item is reserved, the transfer fails.
 260
 261 Returns three values:
 262
 263 =over
 264
 265 =item $dotransfer
 266
 267 is true if the transfer was successful.
 268
 269 =item $messages
 270
 271 is a reference-to-hash which may have any of the following keys:
 272
 273 =over
 274
 275 =item C<BadBarcode>
 276
 277 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 278
 279 =item C<IsPermanent>
 280
 281 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.
 282
 283 =item C<DestinationEqualsHolding>
 284
 285 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.
 286
 287 =item C<WasReturned>
 288
 289 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.
 290
 291 =item C<ResFound>
 292
 293 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>.
 294
 295 =item C<WasTransferred>
 296
 297 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1237
1238 Issue a book. Does no check, they are done in CanBookBeIssued. If we reach this sub, it means the user confirmed if needed.
1239
1240 =over 4
1241
1242 =item C<$borrower> is a hash with borrower informations (from GetMember).
1243
1244 =item C<$barcode> is the barcode of the item being issued.
1245
1246 =item C<$datedue> is a DateTime object for the max date of return, i.e. the date due (optional).
1247 Calculated if empty.
1248
1249 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
1250
1251 =item C<$issuedate> is the date to issue the item in iso (YYYY-MM-DD) format (optional).
1252 Defaults to today.  Unlike C<$datedue>, NOT a DateTime object, unfortunately.
1253
1254 AddIssue does the following things :
1255
1256   - step 01: check that there is a borrowernumber & a barcode provided
1257   - check for RENEWAL (book issued & being issued to the same patron)
1258       - renewal YES = Calculate Charge & renew
1259       - renewal NO  =
1260           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
1261           * RESERVE PLACED ?
1262               - fill reserve if reserve to this patron
1263               - cancel reserve or not, otherwise
1264           * TRANSFERT PENDING ?
1265               - complete the transfert
1266           * ISSUE THE BOOK

2119 the last non-holiday date of the branccode specified in

2632 C<$borrowernumber> is the borrower number of the patron who currently
2633 has the item on loan.
2634
2635 C<$itemnumber> is the number of the item to renew.

2637 C<$override_limit>, if supplied with a true value, causes
2638 the limit on the number of times that the loan can be renewed
2639 (as controlled by the item type) to be ignored. Overriding also allows
2640 to renew sooner than "No renewal before" and to manually renew loans
2641 that are automatically renewed.
2642
2643 C<$CanBookBeRenewed> returns a true value if the item may be renewed. The
2644 item must currently be on loan to the specified borrower; renewals
2645 must be allowed for the item's type; and the borrower must not have
2646 already renewed the loan. $error will contain the reason the renewal can not proceed
