DB_File 1.805

[p5sagit/p5-mst-13.2.git] / ext / DB_File / Changes

1.805 1st September 2002

   * Added support to allow DB_File to build with Berkeley DB 4.1.X

   * Tightened up the test harness to test that calls to untie don't generate
     the "untie attempted while %d inner references still exist" warning.

   * added code to guard against calling the callbacks (compare,hash & prefix) 
     recursively.

   * pasing undef for the flags and/or mode when opening a database could cause
     a "Use of uninitialized value in subroutine entry" warning. Now silenced.

   * DBM filter code beefed up to cope with read-only $_.

1.804 2nd June 2002

   * Perl core patch 14939 added a new warning to "splice". This broke the
     db-recno test harness. Fixed.

   * merged core patches 16502 & 16540.

1.803 1st March 2002

   * Fixed a problem with db-btree.t where it complained about an "our"
     variable redeclaation.

   * FETCH, STORE & DELETE don't map the flags parameter into the
     equivalent Berkeley DB function anymore.

1.802 6th January 2002

   * The message about some test failing in db-recno.t had the wrong test
     numbers. Fixed.

   * merged core patch 13942.

1.801 26th November 2001

   * Fixed typo in Makefile.PL

   * Added "clean" attribute to Makefile.PL
 
1.800 23rd November 2001

   * use pport.h for perl backward compatability code.

   * use new  ExtUtils::Constant module to generate XS constants.

   * upgrade Makefile.PL upgrade/downgrade code to toggle "our" with
     "use vars"

1.79 22nd October 2001

   * Added a "local $SIG{__DIE__}" inside the eval that checks for
     the presence of XSLoader s suggested by Andrew Hryckowin.

   * merged core patch 12277.

   * Changed NEXTKEY to not initialise the input key. It isn't used anyway.

1.79 22nd October 2001

   * Fixed test harness for cygwin

1.78 30th July 2001

   * the test in Makefile.PL for AIX used -plthreads. Should have been
     -lpthreads

   * merged Core patches 
        10372, 10335, 10372, 10534, 10549, 10643, 11051, 11194, 11432

   * added documentation patch regarding duplicate keys from Andrew Johnson


1.77 26th April 2001

   * AIX is reported to need -lpthreads, so Makefile.PL now checks for
     AIX and adds it to the link options.

   * Minor documentation updates.

   * Merged Core patch 9176

   * Added a patch from Edward Avis that adds support for splice with
     recno databases.

   * Modified Makefile.PL to only enable the warnings pragma if using perl
     5.6.1 or better.    

1.76 15th January 2001

   * Added instructions for using LD_PRELOAD to get Berkeley DB 2.x to work
     with DB_File on Linux. Thanks to Norbert Bollow for sending details of
     this approach.


1.75 17th December 2000

   * Fixed perl core patch 7703

   * Added suppport to allow DB_File to be built with Berkeley DB 3.2 --
     btree_compare, btree_prefix and hash_cb needed to be changed.

   * Updated dbinfo to support Berkeley DB 3.2 file format changes.


1.74 10th December 2000

   * A "close" call in DB_File.xs needed parenthesised to stop win32 from
     thinking it was one of its macros.

   * Updated dbinfo to support Berkeley DB 3.1 file format changes.

   * DB_File.pm & the test hasness now use the warnings pragma (when
     available).

   * Included Perl core patch 7703 -- size argument for hash_cb is different
     for Berkeley DB 3.x

   * Included Perl core patch 7801 -- Give __getBerkeleyDBInfo the ANSI C
     treatment.

   * @a = () produced the warning 'Argument "" isn't numeric in entersub'
     This has been fixed. Thanks to Edward Avis for spotting this bug.

   * Added note about building under Linux. Included patches.

   * Included Perl core patch 8068 -- fix for bug 20001013.009 
     When run with warnings enabled "$hash{XX} = undef " produced an
     "Uninitialized value" warning. This has been fixed.

1.73 31st May 2000

   * Added support in version.c for building with threaded Perl.

   * Berkeley DB 3.1 has reenabled support for null keys. The test
     harness has been updated to reflect this.

1.72 16th January 2000

   * Added hints/sco.pl

   * The module will now use XSLoader when it is available. When it
     isn't it will use DynaLoader.

   * The locking section in DB_File.pm has been discredited. Many thanks
     to David Harris for spotting the underlying problem, contributing
     the updates to the documentation and writing DB_File::Lock (available
     on CPAN).

1.71 7th September 1999

   * Fixed a bug that prevented 1.70 from compiling under win32

   * Updated to support Berkeley DB 3.x

   * Updated dbinfo for Berkeley DB 3.x file formats.

1.70 4th August 1999

   * Initialise $DB_File::db_ver and $DB_File::db_version with
     GV_ADD|GV_ADDMULT -- bug spotted by Nick Ing-Simmons.

   * Added a BOOT check to test for equivalent versions of db.h &
     libdb.a/so.

1.69 3rd August 1999

1.67 6th June 1999

   * Added DBM Filter documentation to DB_File.pm

   * Fixed DBM Filter code to work with 5.004

   * A few instances of newSVpvn were used in 1.66. This isn't available in
     Perl 5.004_04 or earlier. Replaced with newSVpv.

1.66 15th March 1999

   * Added DBM Filter code

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

1.64 21st February 1999

   * Tidied the 1.x to 2.x flag mapping code.
   * Added a patch from Mark Kettenis <kettenis@wins.uva.nl> to fix a flag
     mapping problem with O_RDONLY on the Hurd

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.

1.62 30th November 1998

   Added hints/dynixptx.pl.
   Fixed typemap -- 1.61 used PL_na instead of na

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.

1.60
   Changed the test to check for full tied array support

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.

1.58
   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.

1.57
   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.

1.56
   Documented the Solaris 2.5 mutex bug

1.55
   Merged 1.16 changes.

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.

1.53

   Added DB_RENUMBER to flags for recno.

1.52

   Patch from Nick Ing-Simmons now allows DB_File to build on NT.
   Merged 1.15 patch.

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

1.50

    DB_File can now build with either DB 1.x or 2.x, but not both at
    the same time.

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.

1.15

    Patch from Gisle Aas <gisle@aas.no> to suppress "use of undefined
    value" warning with db_get and db_seq.

    Patch from Gisle Aas <gisle@aas.no> 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.


1.14

    Made it illegal to tie an associative array to a RECNO database and
    an ordinary array to a HASH or BTREE database.

1.13

    Minor changes to DB_FIle.xs and DB_File.pm

1.12

    Documented the incompatibility with version 2 of Berkeley DB.

1.11

    Documented the untie gotcha.

1.10

    Fixed fd method so that it still returns -1 for in-memory files
    when db 1.86 is used.

1.09

    Minor bug fix in DB_File::HASHINFO, DB_File::RECNOINFO and
    DB_File::BTREEINFO.

    Changed default mode to 0666.

1.08

    Documented operation of bval.

1.07

    Fixed bug with RECNO, where bval wasn't defaulting to "\n".

1.06

    Minor namespace cleanup: Localized PrintBtree.

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.

1.04

    Minor documentation changes.

    Fixed a bug in hash_cb. Patches supplied by Dave Hammen,
    <hammen@gothamcity.jsc.nasa.govt>.

    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.

1.03

    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.

1.02

    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.

1.01

    Fixed a core dump problem with SunOS.

    The return value from TIEHASH wasn't set to NULL when dbopen
    returned an error.

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.

0.3

    Added prototype support for multiple btree compare callbacks.

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
    <grass@cybercash.com> for spotting the bug.

0.1

    First Release.
