Connection pool bug

Jiří Činčura
Hi *,

I found a bug in connection pool. I *don't* know the root cause. But
anyway I think the code there isn't "good" or "nice", so to speak. But
I currently have an application in front of me, that escalates the
problem, some memory leaks. I think I might go to rewrite the pooling
(I implemented one earlier this year for another provider) and test
it. Hopefully it will be simpler, faster and correct. BUT it might
(will) not have exactly same API/behavior as the old one (and I don't
wanna to try mimic it). So it will be huge breaking change if you rely
on something like that. Of course the major version number will be
incremented. And I hope I'll not introduce more bugs. ;)

Is there anybody against it?

Sometimes you it's better to make breaking changes than to live with the
mess that results from trying to be too accommodating.  I say fix it right.

Re: Connection pool bug

In reply to this post by HERNAN MARTINEZ FOFFANI
OK guys. First thanks for the support. It's not an easy change and
there's a lot of code already and I need to squeeze myself in, with my
concept. But here are some first numbers:

* [1] With connection pooling ON and OLD provider the application
gained about 276KB in ~30 minutes.
* [2] With connection pooling OFF and OLD provider the application
gained 324 bytes in ~30 minutes.
* [3] With connection pooling ON and OLD provider and explicitly
cleaning the pool the application gained about 1KB in ~33 minutes.
* [4] With connection pooling ON and NEW provider the application
*lost* about 2KB in ~30 minutes.

The application I'm using is not 100% deterministic. It's doing
network requests and running some timers. So it pretty much depends
when the snapshot was taken. I think results are looking good. The [2]
and [4] are basically same, similar [3] and [4].

The tests are all green and the test application (obviously) is not
crashing. That gives me like 50% confidence. :) You can find the build
here https://copy.com/Jh2ebP2sPjyv (.NET 4.5). It has same version
number, it's using same sources, only the connection pooling has been
altered. Thus you can just drop it in your application and try it run.
Or create new and stress it. Whatever you want. I'd like to hear
feedback from your. Even if it's just one quick run, let me know. It
will speed up the deploy greatly.

Also. Backporting the feature to .NET 4.0 is going to be easy. To 3.5
harder, because I rely on ConcurrentDictionary that's in 4.0 and
newer. Bummer. Ideas? Drop 3.5 support? I can implement it on my own
with locking (just for 3.5), but is it worth it?

Re: Connection pool bug

André Litfin
For me it's ok dropping 3.5 support - we took 4.0 when 2.0 support was
dropped.

4.0 support would be very appreciated.

I'll take a look right after delivering our update end of the week.

Thank you for your work!

I'm not sure about being able to lose 3.5 support.  We haven't tested,
or planned to test, migrating forward.  If 4.0 backward compatibility is
OK, then it would be OK, though we aren't using any 4.0 language features.

It's probbaly not 100%, but in case you're not relying on some "weird"
behavior you found, you should be OK. You can read:

Re: Connection pool bug

Jiří Činčura
And just a one quick "research" question. What's your common
connection lifetime value for pooling? Do you change it or do you use
the default one?

Re: Connection pool bug

zeko77
I use firebird heavily in sports betting solution, with many simultaneous connections, in desktop environment, web services and virtually everywhere.
Current deployed version is 2.6.0.0, 3.5 build. No major problems here at all.
Polling with default value,and  for events no polling.
Since DB is hit all the time, i guess it polls constantly.
I have not investigated details about possible leaks.

I'm asking to know what "resolution" should the cleanup routine have.
Like if everybody uses lifetime 10s, than resolution 5s is fine, even
10s is fine, though the connection might be in a pool little longer.

Re: Connection pool bug

Danny Gorton
In reply to this post by Jiří Činčura
Thanks for the info Juri.  I failed to mention that we're a
cross-platform solution, with Linux being the main one, so I'm more
concerned with compatibility on Mono than on Windows.  It will just
require some test cycles we don't have right now.

However, that shouldn't really affect what you're doing much since we're
also not considering updating the Firebird provider at this time either.
  The version we have seems to be working just fine and when the time
comes we'll plan a full component analysis, test cycle, and repackaging
effort.  Even if circumstances force us into it sooner than we'd like.

Thanks again,
Danny

Yeah, I just like to hear what are others doing and thinking.

Default,

planned to monitor some things for possible optimizations, but did not
find the time so far.
General   response   time and performance and resources consumption of
my C#/Firebird applications is more than fine with the users, so no hurry.

Thanks to SMS-Timing and even more thanks to you.
I'll  do  some test installs later. Did I get that right and you're in
Siegburg? I'll install and test right there, then.

OK,  I  will nevertheless try to put all required stuff on my yoga and
test it there and then.

I  can't  go  to  two FB-Seminars in 4 days, or my wife will close the
connection  without  doing a proper commit() :-) Otherwise I'd love to
join there.

If  I  should  make  a  recommendation  for  you  guys for the evening
dinners:
We  have  only recently been here: http://www.krcmaupavouka.cz/ with a
group of IT guys.
Very   good  food  and beer and for the atmosphere: check the "galery"
and "interiour" section on the website :-)
