I noticed in https://tools.taskcluster.net/groups/fFnWZGmRS-WSkPXWqUo-jg/tasks/X7TB-SZBRiaZOuMI8-SGAQ/runs/0/logs/public%2Flogs%2Flive.log that the advertised Mercurial client version is only 4.4.1. We would like to get all Mercurial clients running in CI up to version 4.7.1, to take advantage of performance improvements.

on windows taskcluster workers, we've had good results using the msi installers (it's an easier patch for us than the .exe installers which have sometimes been problematic). we normally grab our installers from here: https://www.mercurial-scm.org/release/windows/. today it looks like the msi for 4.7.1 is not yet available. we can quite easily/quickly upgrade to 4.7.0 (using https://www.mercurial-scm.org/release/windows/mercurial-4.7.0-x64.msi). should we go ahead and upgrade to 4.7.0 or should we wait for the 4.7.1 msi release?

:grenade, we will need to wait for 4.7.1 to become available before upgrading Windows workers. 4.7.0 has a performance regression.

Copied mercurial packages on repositories. Installed new mercurial package on OSX staging workers: [root@t-yosemite-r7-380.test.releng.mdc1.mozilla.com ~]# hg --version Mercurial Distributed SCM (version 4.7.1) Test new mercurial package on OSX workers: https://treeherder.mozilla.org/#/jobs?repo=try&revision=5be4fb66a7726856bbce2853612df679ad65379d

these changes were deployed to windows beta workers earlier, where successful builds were validated using hg 4.7.1: https://treeherder.mozilla.org/#/jobs?repo=try&revision=d339170

All jobs are green on OSX beta workers. hg 4.7.1 was validated on OSX

Installed new mercurial package on Ubuntu staging workers: [root@t-linux64-ms-280 ~]# hg --version Mercurial Distributed SCM (version 4.7.1) (see https://mercurial-scm.org for more information) Test new mercurial package on Ubuntu workers: https://treeherder.mozilla.org/#/jobs?repo=try&revision=f989d07bd3f281c464e19e97b0be1a52df67c749

sent another push on try for Linux Workers: https://treeherder.mozilla.org/#/jobs?repo=try&revision=4625533fbabda30da7781a74a695840b600208a4

All jobs are green, hg 4.7.1 was validated in Ubuntu 16.04

windows patch was merged a few hours ago (https://github.com/mozilla-releng/OpenCloudConfig/commit/fb0c0f3dd021cee4c02c82feb3714ce38d0c2a82) and looks quiet too. clones are running normally.

Updated mercurial on Centos: [root@relops-patching1.srv.releng.mdc1.mozilla.com ~]# hg --version Mercurial Distributed SCM (version 4.7.1)

Upgrade mercurial to 4.7.1

Merged https://github.com/mozilla-releng/build-puppet/pull/228

ooks like robustcheckout is not happy with hg 4.7.1.
