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

 255
 256 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 257
 258 C<$newbranch> is the code for the branch to which the item should be transferred.
 259
 260 C<$barcode> is the barcode of the item to be transferred.
 261
 262 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 263 Otherwise, if an item is reserved, the transfer fails.
 264
 265 Returns three values:
 266
 267 =over
 268
 269 =item $dotransfer
 270
 271 is true if the transfer was successful.
 272
 273 =item $messages
 274
 275 is a reference-to-hash which may have any of the following keys:
 276
 277 =over
 278
 279 =item C<BadBarcode>
 280
 281 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 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.

1227
1228 Issue a book. Does no check, they are done in CanBookBeIssued. If we reach this sub, it means the user confirmed if needed.
1229
1230 =over 4
1231
1232 =item C<$borrower> is a hash with borrower informations (from Koha::Patron->unblessed).
1233
1234 =item C<$barcode> is the barcode of the item being issued.
1235
1236 =item C<$datedue> is a DateTime object for the max date of return, i.e. the date due (optional).
1237 Calculated if empty.
1238
1239 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
1240
1241 =item C<$issuedate> is the date to issue the item in iso (YYYY-MM-DD) format (optional).
1242 Defaults to today.  Unlike C<$datedue>, NOT a DateTime object, unfortunately.
1243
1244 AddIssue does the following things :
1245
1246   - step 01: check that there is a borrowernumber & a barcode provided
1247   - check for RENEWAL (book issued & being issued to the same patron)
1248       - renewal YES = Calculate Charge & renew
1249       - renewal NO  =
1250           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
1251           * RESERVE PLACED ?
1252               - fill reserve if reserve to this patron
1253               - cancel reserve or not, otherwise
1254           * TRANSFERT PENDING ?
1255               - complete the transfert
1256           * ISSUE THE BOOK
