0.1 First Release. 0.2 When DB_File is opening a database file it no longer terminates the process if dbopen returned an error. This allows file protection errors to be caught at run time. Thanks to Judith Grass for spotting the bug. 0.3 Added prototype support for multiple btree compare callbacks. 1.0 DB_File has been in use for over a year. To reflect that, the version number has been incremented to 1.0. Added complete support for multiple concurrent callbacks. Using the push method on an empty list didn't work properly. This has been fixed. 1.01 Fixed a core dump problem with SunOS. The return value from TIEHASH wasn't set to NULL when dbopen returned an error. 1.02 Merged OS/2 specific code into DB_File.xs Removed some redundant code in DB_File.xs. Documentation update. Allow negative subscripts with RECNO interface. Changed the default flags from O_RDWR to O_CREAT|O_RDWR. The example code which showed how to lock a database needed a call to sync added. Without it the resultant database file was empty. Added get_dup method. 1.03 Documentation update. DB_File now imports the constants (O_RDWR, O_CREAT etc.) from Fcntl automatically. The standard hash function exists is now supported. Modified the behavior of get_dup. When it returns an associative array, the value is the count of the number of matching BTREE values. 1.04 Minor documentation changes. Fixed a bug in hash_cb. Patches supplied by Dave Hammen, . Fixed a bug with the constructors for DB_File::HASHINFO, DB_File::BTREEINFO and DB_File::RECNOINFO. Also tidied up the constructors to make them -w clean. Reworked part of the test harness to be more locale friendly. 1.05 Made all scripts in the documentation strict and -w clean. Added logic to DB_File.xs to allow the module to be built after Perl is installed. 1.06 Minor namespace cleanup: Localized PrintBtree. 1.07 Fixed bug with RECNO, where bval wasn't defaulting to "\n". 1.08 Documented operation of bval. 1.09 Minor bug fix in DB_File::HASHINFO, DB_File::RECNOINFO and DB_File::BTREEINFO. Changed default mode to 0666. 1.10 Fixed fd method so that it still returns -1 for in-memory files when db 1.86 is used. 1.11 Documented the untie gotcha. 1.12 Documented the incompatibility with version 2 of Berkeley DB. 1.13 Minor changes to DB_FIle.xs and DB_File.pm 1.14 Made it illegal to tie an associative array to a RECNO database and an ordinary array to a HASH or BTREE database. 1.15 Patch from Gisle Aas to suppress "use of undefined value" warning with db_get and db_seq. Patch from Gisle Aas to make DB_File export only the O_* constants from Fcntl. Removed the DESTROY method from the DB_File::HASHINFO module. Previously DB_File hard-wired the class name of any object that it created to "DB_File". This makes sub-classing difficult. Now DB_File creats objects in the namespace of the package it has been inherited into. 1.16 A harmless looking tab was causing Makefile.PL to fail on AIX 3.2.5 Small fix for the AIX strict C compiler XLC which doesn't like __attribute__ being defined via proto.h and redefined via db.h. Fix courtesy of Jarkko Hietaniemi. 1.50 DB_File can now build with either DB 1.x or 2.x, but not both at the same time. 1.51 Fixed the test harness so that it doesn't expect DB_File to have been installed by the main Perl build. Fixed a bug in mapping 1.x O_RDONLY flag to 2.x DB_RDONLY equivalent 1.52 Patch from Nick Ing-Simmons now allows DB_File to build on NT. Merged 1.15 patch. 1.53 Added DB_RENUMBER to flags for recno. 1.54 Fixed a small bug in the test harness when run under win32 The emulation of fd when useing DB 2.x was busted. 1.55 Merged 1.16 changes. 1.56 Documented the Solaris 2.5 mutex bug 1.57 If Perl has been compiled with Threads support,the symbol op will be defined. This clashes with a field name in db.h, so it needs to be #undef'ed before db.h is included. 1.58 Tied Array support was enhanced in Perl 5.004_57. DB_File now supports PUSH,POP,SHIFT,UNSHIFT & STORESIZE. Fixed a problem with the use of sv_setpvn. When the size is specified as 0, it does a strlen on the data. This was ok for DB 1.x, but isn't for DB 2.x. 1.59 Updated the license section. Berkeley DB 2.4.10 disallows zero length keys. Tests 32 & 42 in db-btree.t and test 27 in db-hash.t failed because of this change. Those tests have been zapped. Added dbinfo to the distribution. 1.60 Changed the test to check for full tied array support 1.61 19th November 1998 Added a note to README about how to build Berkeley DB 2.x when using HP-UX. Minor modifications to get the module to build with DB 2.5.x Fixed a typo in the definition of O_RDONLY, courtesy of Mark Kettenis. 1.62 30th November 1998 Added hints/dynixptx.pl. Fixed typemap -- 1.61 used PL_na instead of na 1.63 19th December 1998 * Fix to allow DB 2.6.x to build with DB_File * Documentation updated to use push,pop etc in the RECNO example & to include the find_dup & del_dup methods. 1.64 21st February 1999 * Tidied the 1.x to 2.x flag mapping code. * Added a patch from Mark Kettenis to fix a flag mapping problem with O_RDONLY on the Hurd * Updated the message that db-recno.t prints when tests 51, 53 or 55 fail. 1.65 6th March 1999 * Fixed a bug in the recno PUSH logic. * The BOOT version check now needs 2.3.4 when using Berkeley DB version 2
