I tested cacti with the persist removed and the connection failed (with
mysqli). So I decided to just switch the driver.

Hi TheSin,

Your feedback is much appreciated.

Great, that confirms my testing.

Well, changing the default properly to mysqli AND making this change is
then a good way forward I believe. Cacti SHOULD be calling libphp-adodb
with mysqli, but if some admin forgets to make the change in an already
installed setup, having the package behave properly is extremely nice.

Thanks again.

I agree using mysqli will fix it without change.

I just meant if mysql + php7 is used then you need to remove the persist on the 
dsn, according to the adodb code base that is what forces _pconnect with mysql 
driver, with mysqli persist is ignored.

I just wanted to put that info incase it was an easier option then trying to 
get everyone to update config to use mysqli.  I to am just using mysqli, but I 
wanted to figure out the why and how of it all.

Without any change except for database_type, my testing was already
successful. Do you have any idea when and how this code would be triggered?

As said, switching from mysql to mysqli already fixed issues. Are you

[TheSin]

I believe the real issue isn’t with adodb, it’s line 38 of 
/usr/share/cacti/site/lib/database.php

$dsn = "$db_type://" . rawurlencode($user) . ":" . rawurlencode($pass) . "@" . 
rawurlencode($host) . "/" . rawurlencode($db_name) . "?persist”;

I believe we must remove the persist, so it no longer uses _pconnect in adodb, 
and it’ll switch to using _connect instead.

This is untested though I plan to test it in a bit, but I believe this should 
fix it.

mysqli parameter 6 type was fixed in 5.20.3-2.

So I think the s/mysql/mysqli/ fix should be done in cacti, not in
adodb: mysql has been yelding deprecated warnings for a while. As you
pointed out, its removal has been announced in debian-devel-announce.

I think the source of confusion is that the adodb *driver name* is
called "database_type" in cacti configuration file. This is not the best
name, and maybe adding a comment there would be useful...

I'm reassigning the bug to cacti. Please clone and reassign if you'd
like php and/or adodb to continue to have mysql driver support...

Good to know. So I understand correctly that because php doesn't support
mysql driver anymore, adodb also doesn't. Makes fully sense, but I
wasn't sure.

Will try to get you the required information in the next couple of days,
if the casting to int of $this->port isn't enough to fix the issue.

Well, what I meant was that it would be possible that adodb would still
support mysql (e.g. by wrapping) although php doesn't. I of course have
no clue how feasible that is.

Actually, this is a another issue that is is being worked at. [1][2]

Ubuntu totally removed the mysql driver, and only mysqli is left [3].
I'm not sure what Debian will do, but you probably should not count on
the mysql driver, and has been issuing deprecated warnings for a while
now...

Until a proper fix is released, can you patch your installed
adodb-mysqli.inc.php file, probably at
/usr/share/php/adodb/drivers/adodb-mysqli.inc.php, at line 121, replace
$this->port,
by
(int)$this->port,
and try again the mysqli driver in cacti, please?

I just noticed that Nishanth Aravamudan from Canonical made a patch.
https://patches.ubuntu.com/libp/libphp-adodb/libphp-adodb_5.20.3-1ubuntu1.patch

I'm not sure having the .pc/ files in there is a good idea. But several
changes look good for Debian.

Upstream, you migh want the (int) cast on line 121 of
drivers/adodb-mysqli.inc.php. Completly removing the mysql and mysqlt
drivers seem a bit extreme to me, unless you want to drop php5 support
entirely...

Greetings,

I'm the maintainer for ADOdb. I came here following an issue report [1] in
our tracker.

As mentioned earlier, the 'mysql' driver is no longer available in PHP 7
[2], you must use 'mysqli'.

With regards to the error you're getting with the latter, I would
appreciate if you could provide additional information, preferably a code
snippet allowing us to reproduce the error and/or a detailed stack trace,
so we can get a better understanding of the problem. If you don't mind
posting that directly in [1], that would be most convenient for us.

Not exactly sure what you mean by that...
I'm doing this in my spare time, and I unfortunately don't have too much of
that these days, but we do our best to fix any issues that come up, as fast

I can't give you a commitment for an official release date for ADOdb 5.21,
but I'm hoping to get around to it in the next few weeks.

Depending on how serious adodb takes the mysql support in php7, this may
indeed be what I need for cacti. Just to be clear, once (this may take a
while) the development branch is turned into a proper release, I don't
depend on libphp-adodb anymore anyways, my upstream already move away.

So I would say, if it is ok with you, try to package the latest version
of adodb in Debian and I will try to see if that resolves the issue.

Highest PHP Version support (V5.21) 7

So I wouldn't worry too much and just wait for ADOdb 5.21 release.

I can help with porting the packaging or just take a look at src:php-rrd
or src:xdebug, how to do it efficiently.

I am not going to touch subversion even with a long pole though :).

The config does define that. That would be an extremely simple solution.

Unfortunately, it looks like mysql and mysqli are not compatible (at
least not on my jessie system with php5:
Error on web-page:
FATAL: Cannot connect to MySQL server on 'localhost'. Please make sure
you have specified a valid MySQL database name in 'include/config.php'

But this probably means that I just have to fix cacti if this is truly
properly supported by libphp-adodb. We should just reassign I guess.

It looks like your configuration uses the deprecated mysql driver.

That driver looks dead. You should be using mysqli, if I understand
correctly.

I would try replacing
$database_type = "mysql";
by
$database_type = "mysqli";
maybe?

*If* this work, cacti default driver should be changed too. A quick
"grep -R database_type" in cacti source seems to show that there are
many instances to change...

If you don't have a "database" in your config, it must be using the
wrong "mysql" value: Try adding it.

Does that help?

/usr/share/cacti/site/index.php(25): include('/usr/share/cact...')\n#6 {main}\n 
 thrown in /usr/share/php/adodb/drivers/adodb-mysql.inc.php on line 480

When I use codesearch.d.n to search for where mysql_pconnect is implemented, I
find a lot of hits in the php5 package (test suite) which say:

Deprecated: mysql_pconnect(): The mysql extension is deprecated and will be 
removed in the future: use mysqli or PDO instead in %s on line %d

My understanding is that mysql_pconnect got removed from the php package and
libphp-adodb needs to be ported to php7.0 by using mysqli instead of
mysql_pconnect.

Thanks for considering.
Paul
