Bug description: Cannot open existing hash db3 file with write
Description:
------------
Basically I cannot get php to open an existing (not created by php) db3
hash file when using either "w" or "c". It seems that php is looking for
a btree format. My database is a hash file.
More information:
Trying to read/write information to an existing db3 database (sendmail
aliases file).
I can read the file just fine. But when I try to issue:
$id = dba_open ("aliases5.db", "w", "db3");
I get:
[Wed Oct 8 08:56:44 2003] [error] PHP Warning: dba_open(aliases5.db,w):
Driver initialization failed for handler: db3: Invalid argument in
/usr/local/www/data/maillists/test3.php on line 3
After further testing I dumped the entire aliases db to a text file using
perl and recreated a copy of it with php:
$id = dba_open ("aliases5.db", "c", "db3");
This worked when creating a new file. The file sizes where were different
from the original so performed a db3_dump on the newly created php db3
database. It seems that php is defaulting to a btree format when trying
to open with either w or c. My output from the db3_dump on the php
created db3:
VERSION=3
format=bytevalue
type=btree
HEADER=END
And from the one that sendmail created:
VERSION=3
format=bytevalue
type=hash
h_nelem=172
HEADER=END
Reproduce code:
---------------
//Note you need a hash database for this to fail
$id = dba_open ("aliases5.db", "w", "db3");
if (!$id) {
echo "dba_open failed\n";
exit;
}
dba_insert ("bkey", "bvalue", $id);
$key = dba_firstkey ($id);
while ($key != false)
{
echo "<br>Key: " . $key . "->Value: " . dba_fetch ( $key, $id);
$key = dba_nextkey ($id);
}
dba_close ($id);
Expected result:
----------------
To be able to insert into an existing (not created by php) db3 hash
database.
Actual result:
--------------
[Wed Oct 8 08:56:44 2003] [error] PHP Warning: dba_open(aliases5.db,w):
Driver initialization failed for handler: db3: Invalid argument in
/usr/local/www/data/maillists/test3.php on line 3
