 136 =head1 NAME
 137
 138 C4::Circulation - Koha circulation module
 139
 140 =head1 SYNOPSIS
 141
 142 use C4::Circulation;
 143
 144 =head1 DESCRIPTION
 145
 146 The functions in this module deal with circulation, issues, and
 147 returns, as well as general information about the library.
 148 Also deals with inventory.
 149
 150 =head1 FUNCTIONS
 151
 152 =head2 barcodedecode
 153
 154   $str = &barcodedecode($barcode, [$filter]);
 155
 156 Generic filter function for barcode string.
 157 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 158 Will do some manipulation of the barcode for systems that deliver a barcode
 159 to circulation.pl that differs from the barcode stored for the item.
 160 For proper functioning of this filter, calling the function on the
 161 correct barcode string (items.barcode) should return an unaltered barcode.
 162
 163 The optional $filter argument is to allow for testing or explicit
 164 behavior that ignores the System Pref.  Valid values are the same as the
 165 System Pref options.

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

1240
1241 Issue a book. Does no check, they are done in CanBookBeIssued. If we reach this sub, it means the user confirmed if needed.
1242
1243 =over 4
1244
1245 =item C<$borrower> is a hash with borrower informations (from Koha::Patron->unblessed).
1246
1247 =item C<$barcode> is the barcode of the item being issued.
1248
1249 =item C<$datedue> is a DateTime object for the max date of return, i.e. the date due (optional).
1250 Calculated if empty.
1251
1252 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
1253
1254 =item C<$issuedate> is the date to issue the item in iso (YYYY-MM-DD) format (optional).
1255 Defaults to today.  Unlike C<$datedue>, NOT a DateTime object, unfortunately.
1256
1257 AddIssue does the following things :
1258
1259   - step 01: check that there is a borrowernumber & a barcode provided
1260   - check for RENEWAL (book issued & being issued to the same patron)
1261       - renewal YES = Calculate Charge & renew
1262       - renewal NO  =
1263           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
1264           * RESERVE PLACED ?
1265               - fill reserve if reserve to this patron
1266               - cancel reserve or not, otherwise
1267           * TRANSFERT PENDING ?
1268               - complete the transfert
1269           * ISSUE THE BOOK
