 104
 105 =head1 SYNOPSIS
 106
 107 use C4::Circulation;
 108
 109 =head1 DESCRIPTION
 110
 111 The functions in this module deal with circulation, issues, and
 112 returns, as well as general information about the library.
 113 Also deals with stocktaking.
 114
 115 =head1 FUNCTIONS
 116
 117 =head2 barcodedecode
 118
 119 =head3 $str = &barcodedecode($barcode, [$filter]);
 120
 121 =over 4
 122
 123 =item Generic filter function for barcode string.
 124 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 125 Will do some manipulation of the barcode for systems that deliver a barcode
 126 to circulation.pl that differs from the barcode stored for the item.
 127 For proper functioning of this filter, calling the function on the
 128 correct barcode string (items.barcode) should return an unaltered barcode.
 129
 130 The optional $filter argument is to allow for testing or explicit
 131 behavior that ignores the System Pref.  Valid values are the same as the
 132 System Pref options.

 208 =head2 transferbook
 209
 210 ($dotransfer, $messages, $iteminformation) = &transferbook($newbranch, $barcode, $ignore_reserves);
 211
 212 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 213
 214 C<$newbranch> is the code for the branch to which the item should be transferred.
 215
 216 C<$barcode> is the barcode of the item to be transferred.
 217
 218 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 219 Otherwise, if an item is reserved, the transfer fails.
 220
 221 Returns three values:
 222
 223 =head3 $dotransfer
 224
 225 is true if the transfer was successful.
 226
 227 =head3 $messages
 228
 229 is a reference-to-hash which may have any of the following keys:
 230
 231 =over 4
 232
 233 =item C<BadBarcode>
 234
 235 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 236
 237 =item C<IsPermanent>
 238
 239 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.
 240
 241 =item C<DestinationEqualsHolding>
 242
 243 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.
 244
 245 =item C<WasReturned>
 246
 247 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.
 248
 249 =item C<ResFound>
 250
 251 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>.
 252
 253 =item C<WasTransferred>
 254
 255 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

 841 =item C<$borrower> is a hash with borrower informations (from GetMemberDetails).
 842
 843 =item C<$barcode> is the barcode of the item being issued.
 844
 845 =item C<$datedue> is a C4::Dates object for the max date of return, i.e. the date due (optional).
 846 Calculated if empty.
 847
 848 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
 849
 850 =item C<$issuedate> is the date to issue the item in iso (YYYY-MM-DD) format (optional).
 851 Defaults to today.  Unlike C<$datedue>, NOT a C4::Dates object, unfortunately.
 852
 853 AddIssue does the following things :
 854
 855   - step 01: check that there is a borrowernumber & a barcode provided
 856   - check for RENEWAL (book issued & being issued to the same patron)
 857       - renewal YES = Calculate Charge & renew
 858       - renewal NO  =
 859           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
 860           * RESERVE PLACED ?
 861               - fill reserve if reserve to this patron
 862               - cancel reserve or not, otherwise
 863           * TRANSFERT PENDING ?
 864               - complete the transfert
 865           * ISSUE THE BOOK

1185 branch, same category), then failing that, default_circ_rules
1186 (default branch, default category).
1187

1572 moving the C<issues> row to C<old_issues> and
1573 setting C<returndate> to the current date, or
1574 the last non-holiday date of the branccode specified in
1575 C<dropbox_branch> .  Assumes you've already checked that
1576 it's safe to do this, i.e. last non-holiday > issuedate.

1578 if C<$returndate> is specified (in iso format), it is used as the date
