Thread: Minimum bison and flex versions
Per the meson thread, we also need to have a conversation about
what's the oldest bison and flex versions still worth supporting.
The ones that had been our reference points are no longer
represented in the buildfarm, and it seems not likely to be
worth resurrecting copies of those.
As fodder for discussion, here's a scraping of the currently-tested
versions. (This counts only animals running configure, ie not MSVC.
Also, my query looked back a few months, so some recently-dead
animals are still here.)
regards, tom lane

Hi,

If we also count older branches, there's a few alive cases of old bison:
REL_10_STABLE | {2,4,1} | 2022-09-01 12:30:05 | {castoroides,frogmouth}
REL_10_STABLE | {2,4,2} | 2022-09-01 08:30:15 | {brolga}
All the other animals using bison < 3.0.2 are dead. There's two live animals
using 3.0.2:
HEAD | {3,0,2} | 2022-09-01 19:23:26 | {chipmunk,topminnow}
So it looks like we could trivialy go to 3.0 as the minimum. The number of
animals using some version of 3.0 is quite large:
chipmunk,topminnow,parula,perch,buri,cotinga,tern,elasmobranch,trilobite,urocryon,vulpes,avocet,wobbegong,ayu,batfish,cavefish,bichir,grison,hippopotamus,hornet,hoverfly,chimaera,jay,chub,clam,blossomcrown,lorikeet,mandrill,mantid,massasauga,cuon,curculio,demoiselle,quokka,rhinoceros,mussurana,dhole,butterflyfish,snakefly,spurfowl,sungazer,tadarida,bonito
So I don't think we could easily go to something newer.
There's nothing in 3.1-3.5 release notes [1] that looks particularly helpful
for us to require on a quick glance. 2.6 would be nice to have as noted
e.g. in
https://postgr.es/m/CAFBsxsEospoUX%3DQYkfC%3DWcJqNB%2BiZtBf%3DBaRwn-zbHa48X0NKQ%40mail.gmail.com
but as noted in Tom's followup, apple still ships 2.3.
2.3 is the last bison version using GPLv2, so it's unlikely that apple will
ever update. Given that I'm not sure how much we should feel beholden to
support that, given that we'll eventually have to bite the bullet.
For flex, the minimum after prariedog's demise seems to be 2.5.35, with a
decent population. Skimming the release notes [2] between 2.5.31 and 2.5.35
doesn't show anything particularly interesting. But given that we don't have
coverage and that 2.5.35 was released in 2008, it seems we could just update
our requirements so that we have test coverage?
Greetings,
Andres Freund

I'm not sure why frogfish hasn't reported in for a few days, but these
others are certainly still live.
longfin and sifaka are using the Apple-provided copy of bison.
If we move the minimum version above 2.3, that will cause some
pain for all Mac-based developers. Maybe not much, because most
probably can get it from homebrew or macports, but some.

Seeing that they're au courant on flex (2.6.4), it certainly looks like
a license problem rather than that they just don't care about these tools
at all. Nonetheless, I want to see a pretty solid benefit from breaking
compatibility with 2.3, and I'm not convinced we're there yet.

Yeah, I think setting the minimum to 2.5.35 is a no-brainer there.
(If memory serves, the only major difference between 2.5.33 and 2.5.35
was a security fix that LTS distros cherry-picked without changing
their version numbers, so that anything claiming to be 2.5.33 today
is probably effectively 2.5.35 anyway.) There aren't a huge number
of animals still on 2.5.35:
frogfish | 2022-08-21 17:59:26 | configure: using flex 2.5.35
hoverfly | 2022-09-02 16:02:01 | configure: using flex 2.5.35

snapper | 2022-09-02 13:38:22 | configure: using flex 2.5.35
but on the other hand I don't know that we'd gain anything by making
them update.
I'd be content for now to set the minimums at 2.3 and 2.5.35.

There are good reasons for a dev to install a newer Bison, like better diagnostics, so used this language. -- John Naylor EDB: http://www.enterprisedb.com
