Обсуждение: Maintenance Policy?
Howdy Hackers, Is there a published maintenance policy somewhere? Something that says for how long the project supports minor releases of PostgreSQL. For example, does 7.4 still get bug fixes and minor releases? If not, how does one know when support for a major version has been dropped? Thanks, David

Hmm, I thought we dropped support for 7.4 a while ago, and there's no download link for it on www.postgresql.org anymore. But looking at the CVS history, I see that others are still committing fixes to 7.4 branch. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com

But looking at the > CVS history, I see that others are still committing fixes to 7.4 branch. > Indeed we are :-) I don't recall any decision not to continue support for 7.4, which is still quite solid, if a bit limited. (I had to help rescue somebody who had been running 6.5 recently, so don't think people aren't running extremely old branches.) If you're going to backpatch something, going back a couple more branches is often not a great difficulty, unless the code drift is large. Most backpatches are relatively limited in scope. If there is something that is invasive and difficult, that's a possible reason to drop support. Most users don't want to be upgrading all the time, and I believe we inspire some confidence in our user base by a) being quite conservative about what we backpatch, and b) giving our stable branches quite long lifetimes. BTW, 7.4 is less than six years old. If we were going to impose an arbitrary branch lifetime limit, I think five or six years is about right. cheers andrew

I'm still theoretically on the hook for 7.3, too. In practice I doubt
I'd be able to get any but really critical security updates into RHEL-3
or RHEL-4 at this point, so the notion that we're supporting these old
versions because Red Hat wants 'em is probably not holding any water
anymore.
I'd personally be perfectly happy with a community decision to desupport
7.4 now, or perhaps after the next set of update releases (which we're
probably overdue for, BTW). We cannot support an indefinitely large set
of back branches, and a five-year lifespan seems about right to me.

I had kind of thought it was five active versions, which translates to more or less the same thing. In that case, 7.4 would shortly be dropped. So I ask: 1. Should 7.4 be dropped after the release of 7.4.26? 2. Should there be an articulated, published maintenance policy? Or, at least, a prominent list saying, "these are the versions we actively support as of now"? Thanks, David

Perhaps a maintenance page on the site with a table for each version of PostgreSQL, in reverse chronological order, showing the initial release date and the date of last supported release (anticipated, perhaps, to be something like Sept 1 for 7.4). So something like: branch | released | curr_version | curr_date | final_date --------+------------+--------------+------------+------------ 8.4 | 2009-07-01 | 8.4.0 | 2009-07-01 | 8.3 |2008-02-04 | 8.3.7 | 2009-03-16 | 8.2 | 2006-12-05 | 8.2.13 | 2009-03-16 | 8.1 | 2005-11-08 | 8.1.17 | 2009-03-16 | 8.0 | 2005-01-19 | 8.0.21 | 2009-03-16 | 7.4 | 2003-11-17 | 7.4.25 | 2009-03-16| 2009-09-01 (projected) 7.3 | 2002-11-27 | 7.3.21 | 2008-01-07 | 2008-01-07 7.2 | 2002-02-04 | 7.2.8 | 2005-05-09| 2005-05-09 7.1 | 2001-04-13 | 7.1.3 | 2001-08-15 | 2001-08-15 7.0 | 2000-05-08 | 7.0.3 |2000-11-11 | 2000-11-11 Best, David

All, I'd suggest that we publish an official policy, with the following dates for "EOL": 7.4 2009-08-01 8.0 2010-02-01 8.1 2011-01-01 8.2 2012-01-01 8.3 2013-03-01 8.4 2014-08-01 EOL would be defined as: "After the above dates, the PostgreSQL Project will not promise to provide any minor (patch or update) releases of the respective versions, whether for security, data loss, or any other issue. Individual companies might choose to continue backporting patches to earlier versions, and if they contribute these update releases we will make them available. However, after the final minor release date, there is no guarantee that updates will be available and users should upgrade." -- Josh Berkus PostgreSQL Experts Inc. www.pgexperts.com

I have no objection to setting an EOL date for 7.4 now, but I think it
is premature to set EOL dates for later versions. I suppose the policy
you have in mind here (but are not spelling out) is that versions will
be EOL'd five years after release no matter what. I'm not convinced
that we need to have a policy for that at all; but if we were to set
one, I'd prefer to define it in terms of the maximum number of back
branches we want to deal with. (So it'd go more like "a version will be
EOL'd shortly after the release of the fifth subsequent major version".)
Or, if you want something calendar-based, it should be driven off the
release of the immediately following major version (i.e., "not less than
four years after the release of the next major version"), so that people
would always know that they have at least N years' support when they
adopt the current major version.
But on the whole I think we should NOT have such a policy, at all.
If we'd enunciated such a thing in 2005, we'd still be on the hook to
support 8.0 on Windows; or else have had to go back on our word. The
truth of the matter is that the community will make reasonable efforts
to support back branches but we are not going to set anything in stone.
If someone wants a guaranteed EOL date, they ought to be contracting
with a commercial support company and paying appropriately.

It seems pretty speculative to propose end of support dates for every active release at this point; what if it takes us longer than planned to get the next few releases out? I think we could try to set dates for the older releases. ...Robert

I don't mind the idea of saying "our intention is to support new
releases for about five years", or something equally squishy.
But a list of dates in black and white does not look reasonable,
especially not dates that are four or five years out for versions
that have zero track record. We have no idea whatsoever what the
future will bring.

Instead of "LatestReleases" (which doesn't even list 7.4 when I just looked), it could be something like "Current Releases". Then whenEOL is announced, the release could be suffixed with the EOL date (i.e. 7.4.25 EOL 2009-12-31 - maybe even with the EOLdate in bold and/or red) which would link to the EOL announcement or general EOL statement page.<br /><br /> I think thata "EOL Statement" link to a page with the generic statement placed just below the oldest release could be helpful aswell.<br /><br /> Cheers,<br /> Steve<br /><br />

I think that it would be useful to have the squish comment, but also a list of versions that are definitely no longer supported, and when support ceased. Best, David

I'm not convinced How about "five (or four or...) years after the next version is released?" That takes into account longer release schedules. That way we aren't guaranteeing support for a hard term for a release but rather that we will support it for a specified time from the date it is superceded by the next version. -- D'Arcy J.M.

Hmmm, how about this? "The current policy of the PostgreSQL community is to stop providing minor versions (patches or updates) of PostgreSQL five years after a version of PostgreSQL is released. In general, users can expect to continue to be able to get community updates for five years. However, there have been exceptions in both directions. Some companies choose to continue back-patching PostgreSQL and make those updates available to the community past the fifth anniversary. Other times issues with build tools have caused us to discontinue a particular version early, such as 8.0 and 8.1 for Windows, which stopped getting updates in binary form after only 2 years. Overall, if you have specific lifetime requirements for your database products, we strongly urge you to get a long-term support contract with a PostgreSQL support vendor <link>. As examples of this policy, below are the dates at which updates of specific version became unavailable: <table here> " -- Josh Berkus PostgreSQL Experts Inc. www.pgexperts.com

I think this is putting it the wrong way round. We should say that the general intention is to maintain a version for at least five years, or some similar formulation. cheers andrew

I assume for a commercial product, such a statement would mean something like "I could get my money back or sue for breach of contract or similar if the vendor stops providing support before such a date." For an open source project, would such a statement really mean anything more than "we'll provide support as long as some community members feel like it, and we guess that's about 5 years"? If so, what?

Well, what I'm really concerned about is letting people know that we expect to *stop* providing update versions after 5 years. Every year, this seems to take some people by surprise. -- Josh Berkus PostgreSQL Experts Inc. www.pgexperts.com

That seems like a reasonable thing to say and you've just said it more simply than any of your previous proposals. I suggest you just go with the above. > Every year, this seems to take some people by surprise. For what it's worth I find it hard to believe anyone's really surprised by this. Nearly all other open source projects stop supporting old branches as soon as there's a newer branch is released. -- greg http://mit.edu/~gsstark/resume.pdf

Our product holds data - and that's an extremely valuable resource to end users (e.g. companies). Nobody wants to risk problems and/or suffer long downtimes. Our complete lack of an in-place upgrade is what is really making us do the extra effort to support old versions. Thankfully, it looks like we've finally started down the road to a serious attempt at an upgrade process. For what it's worth, I think our release history and current necessarily ad-hoc and somewhat arbitrary release process makes it difficult to make anything but the vaguest statement on dates, and I'd rather we didn't. - -- Greg Sabino Mullane greg@turnstep.com End Point Corporation PGP Key: 0x14964AC8 200907122044 http://biglumber.com/x/web?pk=2529DF6AB8F79407E94445B4BC9B906714964AC8 -----BEGIN PGP SIGNATURE----- iEYEAREDAAYFAkpahQkACgkQvJuQZxSWSsjehACg7208VOSWEoJuHWMORnhAg82t IugAn0vSGBI9qUvAUDb3msMeyRzjjuy7 =tcmE -----END PGP SIGNATURE-----

The discussion had already covered that ground. If someone wants a promise they'll have to fork over money to one of the companies which sell such things. That's why Josh's last email where he said just that we *didn't* plan to support releases for longer than 5 years is much better than the other attempts to say how long we *did* plan to support releases. -- greg http://mit.edu/~gsstark/resume.pdf
