Upgrade monolog to 1.22
Closed, ResolvedPublic


We're starting to lag behind a bit. We're on 1.18.2, 1.22 (November 2016) is out, and there's over 200 commits to master after that, which suggest 1.23 probably isn't far away is *only* 102 commits, so it looks like a lot more dev has happened after 1.22

Not many breaking changes (at least, according to the release notes), don't know which directly affect us. Some PHP 7.0 and 7.1 fixes come in along with it in 1.22 too which are always helpful as we're making other PHP 7 support changes across the board

Will commit the basic vendor and core bump patches and see what jenkins thinks of it all

PhpStorms static analysis doesn't see anything wrong in that sense...

Break: Reverted the addition of $context when the ErrorHandler handles regular php errors from 1.20.0 as it was causing issues

We were never on 1.20, so that isn't a problem


Break: StreamHandler will not close streams automatically that it does not own. If you pass in a stream (not a path/url), then it will not close it for you. You can retrieve those using getStream() if needed

Neither of which are affected by that break

The master branch is the 2.0 release (see and requires PHP 7 (so a bump to 2.0 would require to bump MW requirements before). It seems that the master branch and the 1.x branch are quite kept in sync, there are a lot of merges from 1.x to master, meaning that most issues are fixed both in 1.x and in master.

Note also that a commit (5bc1e18, 18 December 2015) says that HHVM support was dropped “for now” in master branch.

Cheers for the heads up.

All the more reason to get to 1.22 then i guess, I'm guessing there won't be a 1.23, but maybe some 1.22 point releases for some bug fixes if anything is found

The chances of us bumping to a min supported PHP 7 version in MW isn't likely to happen for a while, and certainly, dropping "hhvm support" would be a blocker, if that was the case (looking at it looked mostly like a workaround for travis, rather than actual "hhvm support" in the code)
