New Comment:
it doesn´t work, but the behavior changed a little:
Every insert without mysqli_stmt_send_long_data()
inserts 0 Bytes into the blob field, with this function
it works as in the other version (5.0.5)

it seems to work with mysqli_stmt_send_long_data(), but it has to work
without, as the doc says, you only have to use it, if you send data
larger than max_allowed_packet. This value is set to 16M, that data is
only 2mb.
Kind regards

Description:
------------
Inserting a data into a blob column only inserts some of the data, in
most cases between 1 and 200 Bytes, but not allways the same and never
all data (which is in this case about 2 mb). I also tried it with
mysqli_stmt_send_long_data(), but that was not working either.
The table is as followes:
CREATE TABLE
dbfs_data_chunk (
fileid smallint(5) unsigned NOT NULL,
version smallint(5) unsigned NOT NULL default '0',
data mediumblob,
PRIMARY KEY (fileid,version)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
MySQL-Version: 5.0.15
If i do a base64_encode() it works, but this isn´t a solution, only a
bad workaround, which is not acceptable.
I also tried MyISAM, the same result.
Reproduce code:
---------------
<?php
$GLOBALS['CONN'] = mysqli_connect(...);
$s =
file_get_contents('/usr/portage/distfiles/vim-runtime-20050601.tar.bz2');
$one = 1;
$two = 2;
$q = 'INSERT INTO dbfs_data_chunk VALUES (?,?,?)';
$stmt = mysqli_stmt_init($GLOBALS['CONN']);
mysqli_stmt_prepare($stmt,$q);
mysqli_stmt_bind_param($stmt,'iib',$one,$two,$s);
//mysqli_stmt_send_long_data($stmt,2,$s);
mysqli_stmt_execute($stmt);
mysqli_stmt_close($stmt);
exit;
?>
Expected result:
----------------
Should insert the binary data into the table
Actual result:
--------------
only 1 to 200 Bytes get inserted.
