8 When DB_File is opening a database file it no longer terminates the
9 process if dbopen returned an error. This allows file protection
10 errors to be caught at run time. Thanks to Judith Grass
11 <grass@cybercash.com> for spotting the bug.
15 Added prototype support for multiple btree compare callbacks.
19 DB_File has been in use for over a year. To reflect that, the
20 version number has been incremented to 1.0.
22 Added complete support for multiple concurrent callbacks.
24 Using the push method on an empty list didn't work properly. This
29 Fixed a core dump problem with SunOS.
31 The return value from TIEHASH wasn't set to NULL when dbopen
36 Merged OS/2 specific code into DB_File.xs
38 Removed some redundant code in DB_File.xs.
42 Allow negative subscripts with RECNO interface.
44 Changed the default flags from O_RDWR to O_CREAT|O_RDWR.
46 The example code which showed how to lock a database needed a call
47 to sync added. Without it the resultant database file was empty.
55 DB_File now imports the constants (O_RDWR, O_CREAT etc.) from Fcntl
58 The standard hash function exists is now supported.
60 Modified the behavior of get_dup. When it returns an associative
61 array, the value is the count of the number of matching BTREE
66 Minor documentation changes.
68 Fixed a bug in hash_cb. Patches supplied by Dave Hammen,
69 <hammen@gothamcity.jsc.nasa.govt>.
71 Fixed a bug with the constructors for DB_File::HASHINFO,
72 DB_File::BTREEINFO and DB_File::RECNOINFO. Also tidied up the
73 constructors to make them -w clean.
75 Reworked part of the test harness to be more locale friendly.
79 Made all scripts in the documentation strict and -w clean.
81 Added logic to DB_File.xs to allow the module to be built after
86 Minor namespace cleanup: Localized PrintBtree.
90 Fixed bug with RECNO, where bval wasn't defaulting to "\n".
94 Documented operation of bval.
98 Minor bug fix in DB_File::HASHINFO, DB_File::RECNOINFO and
101 Changed default mode to 0666.
105 Fixed fd method so that it still returns -1 for in-memory files
106 when db 1.86 is used.
110 Documented the untie gotcha.
114 Documented the incompatibility with version 2 of Berkeley DB.
118 Minor changes to DB_FIle.xs and DB_File.pm
122 Made it illegal to tie an associative array to a RECNO database and
123 an ordinary array to a HASH or BTREE database.
127 Patch from Gisle Aas <gisle@aas.no> to suppress "use of undefined
128 value" warning with db_get and db_seq.
130 Patch from Gisle Aas <gisle@aas.no> to make DB_File export only the
131 O_* constants from Fcntl.
133 Removed the DESTROY method from the DB_File::HASHINFO module.
135 Previously DB_File hard-wired the class name of any object that it
136 created to "DB_File". This makes sub-classing difficult. Now
137 DB_File creats objects in the namespace of the package it has been
143 A harmless looking tab was causing Makefile.PL to fail on AIX 3.2.5
145 Small fix for the AIX strict C compiler XLC which doesn't like
146 __attribute__ being defined via proto.h and redefined via db.h. Fix
147 courtesy of Jarkko Hietaniemi.
151 DB_File can now build with either DB 1.x or 2.x, but not both at
156 Fixed the test harness so that it doesn't expect DB_File to have
157 been installed by the main Perl build.
160 Fixed a bug in mapping 1.x O_RDONLY flag to 2.x DB_RDONLY equivalent
164 Patch from Nick Ing-Simmons now allows DB_File to build on NT.
169 Added DB_RENUMBER to flags for recno.
173 Fixed a small bug in the test harness when run under win32
174 The emulation of fd when useing DB 2.x was busted.
180 Documented the Solaris 2.5 mutex bug
183 If Perl has been compiled with Threads support,the symbol op will be
184 defined. This clashes with a field name in db.h, so it needs to be
185 #undef'ed before db.h is included.
188 Tied Array support was enhanced in Perl 5.004_57. DB_File now
189 supports PUSH,POP,SHIFT,UNSHIFT & STORESIZE.
191 Fixed a problem with the use of sv_setpvn. When the size is
192 specified as 0, it does a strlen on the data. This was ok for DB
193 1.x, but isn't for DB 2.x.
196 Updated the license section.
198 Berkeley DB 2.4.10 disallows zero length keys. Tests 32 & 42 in
199 db-btree.t and test 27 in db-hash.t failed because of this change.
200 Those tests have been zapped.
202 Added dbinfo to the distribution.
205 Changed the test to check for full tied array support
207 1.61 19th November 1998
209 Added a note to README about how to build Berkeley DB 2.x when
211 Minor modifications to get the module to build with DB 2.5.x
212 Fixed a typo in the definition of O_RDONLY, courtesy of Mark Kettenis.
214 1.62 30th November 1998
216 Added hints/dynixptx.pl.
217 Fixed typemap -- 1.61 used PL_na instead of na

305 thinking it was one of its macros.
307 * Updated dbinfo to support Berkeley DB 3.1 file format changes.
