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

 253
 254 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 255
 256 C<$newbranch> is the code for the branch to which the item should be transferred.
 257
 258 C<$barcode> is the barcode of the item to be transferred.
 259
 260 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 261 Otherwise, if an item is reserved, the transfer fails.
 262
 263 Returns three values:
 264
 265 =over
 266
 267 =item $dotransfer
 268
 269 is true if the transfer was successful.
 270
 271 =item $messages
 272
 273 is a reference-to-hash which may have any of the following keys:
 274
 275 =over
 276
 277 =item C<BadBarcode>
 278
 279 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 280
 281 =item C<IsPermanent>
 282
 283 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.
 284
 285 =item C<DestinationEqualsHolding>
 286
 287 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.
 288
 289 =item C<WasReturned>
 290
 291 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.
 292
 293 =item C<ResFound>
 294
 295 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>.
 296
 297 =item C<WasTransferred>
 298
 299 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1257
1258 Issue a book. Does no check, they are done in CanBookBeIssued. If we reach this sub, it means the user confirmed if needed.
1259
1260 =over 4
1261
1262 =item C<$borrower> is a hash with borrower informations (from GetMember or GetMemberDetails).
1263
1264 =item C<$barcode> is the barcode of the item being issued.
1265
1266 =item C<$datedue> is a DateTime object for the max date of return, i.e. the date due (optional).
1267 Calculated if empty.
1268
1269 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
1270
1271 =item C<$issuedate> is the date to issue the item in iso (YYYY-MM-DD) format (optional).
1272 Defaults to today.  Unlike C<$datedue>, NOT a DateTime object, unfortunately.
1273
1274 AddIssue does the following things :
1275
1276   - step 01: check that there is a borrowernumber & a barcode provided
1277   - check for RENEWAL (book issued & being issued to the same patron)
1278       - renewal YES = Calculate Charge & renew
1279       - renewal NO  =
1280           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
1281           * RESERVE PLACED ?
1282               - fill reserve if reserve to this patron
1283               - cancel reserve or not, otherwise
1284           * TRANSFERT PENDING ?
1285               - complete the transfert
1286           * ISSUE THE BOOK

1621 patron of the given category can have at the given
1622 branch.  If the value is undef, no limit.

1628 This will first check for a specific branch and
1629 category match from branch_borrower_circ_rules.
1630
1631 If no rule is found, it will then check default_branch_circ_rules
1632 (same branch, default category).  If no rule is found,
1633 it will then check default_borrower_circ_rules (default
1634 branch, same category), then failing that, default_circ_rules
1635 (default branch, default category).
1636
1637 If no rule has been found in the database, it will default to

2181 setting C<returndate> to the current date, or
2182 the last non-holiday date of the branccode specified in
