#21743 [Asn]: Driver initialization failed for handler: db3 (and db2)

ID: 21743 User updated by: priyadi@priyadi.net Reported By: priyadi@priyadi.net Status: Assigned Bug Type: DBM/DBA related Operating System: RedHat Linux 7.2 PHP Version: 4.3.0 Assigned To: helly New Comment: Hello, sorry for not responding for so long. I have another observation to this elusive problem. - It fails when using mode 'c' but the file doesn't exist already - It succeeds when using mode 'n' and the file doesn't already exist - It succeeds when using mode 'c' and the file exists and it is a valid db3 btree - It fails when using mode 'c' and the file exists but it is not a valid db3 btree Regarding db4 version, I lost access to the system but I think it is version 4.0.14. Previous Comments: ------------------------------------------------------------------------ [2003-01-31 01:28:04] helly@php.net Please update: ext/dba/config.m4 This fixes some problems when linking against a specific library version. If you do not use your systems default db library you must not include ndbm support since that is based on db1 which in turn is db-1.85 or based on db-x where x is 1.85 or x >= 2. I tried the following: - db-3.2 (not shared) and it works. - db-4.1.25 (shared/not shared) and it works. - db-3.3 from system rpm (not shared) and it works. - db-3.3 from source (shared) and it works So i will ask sleepycat for known problems and maybe disable shared dba in case of db-3.2. I missed to answer your question: db libraries *can* do file locking but we tell the library not to do so and use our own locking. To unalize your db4 problems: What extact version are you using (ldd) and which config (but ldd should be enough). ------------------------------------------------------------------------ [2003-01-30 11:38:18] priyadi@priyadi.net I also encountered segfaults with db4 compiled with --with-db3=dir but not with db3 supplied by redhat. ------------------------------------------------------------------------ [2003-01-29 18:59:10] helly@php.net Called my contact at Berkeley and got the link to the 3.2 version. Now i am able to reproduce a segfault...I'll look into deeper ASAP ------------------------------------------------------------------------ [2003-01-26 23:49:22] priyadi@priyadi.net I've tested it with db3-3.3 (RedHat 7.3) and also experienced the same result :(. Older berkeley db sources can be obtained from http://rpmfind.net as SRPMSs. I've also uploaded my binary dba.so to http://priyadi.net/php/dba.so if that will help. It is compiled with --with-flatfile --with-cdb --with-db3. Compiled on a RedHat 7.2 system, and db3-3.2.9. ------------------------------------------------------------------------ [2003-01-26 08:01:02] helly@php.net I've reconfigured my system with shared dba and db3-3.3 and cannot reproduce you results. Hopefully i can get a copy of the db-3.2 source distrubution which is no longer online :-( ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
