I likewise got an incomplete notification email about @matmarex’ reply there:

I wonder if it’s because I started that comment thread on a file that the Gerrit change originally didn’t touch at all? You can leave comments on untouched files by editing the URL, but perhaps it’s not fully supported by Gerrit.

Change 993695 had a related patch set uploaded (by Hashar; author: Hashar):

[operations/puppet@production] gerrit: sync soy email template with version 3.7

https://gerrit.wikimedia.org/r/993695

We have forked the templates used to generate emails notifications and looks like I forgot to rebase/update them as I upgraded Gerrit. The Puppet patch above rebase our forked templates so at least we will be aligned with upstream.

You can try/spam the test repository at https://gerrit.wikimedia.org/g/test/gerrit-ping :)

Change 993695 merged by Dzahn:

[operations/puppet@production] gerrit: sync soy email template with version 3.7

https://gerrit.wikimedia.org/r/993695

I have synced the template used to generate the emails, then modules/gerrit/files/site/etc/mail/Comment.soy is for the plain text emails so that is a bit irrelevant to this task and I don't think the sole customization we have in it justify keeping it.

Does this issue still happen to you?

Yes, just tested at https://gerrit.wikimedia.org/r/c/test/test/+/1034126

A upstream issue was filed that I think is related to this: https://issues.gerritcodereview.com/issues/387440281

Bug caused by https://gerrit-review.googlesource.com/c/gerrit/+/300007/ at least according to https://gerrit-review.googlesource.com/c/gerrit/+/300007/14/java/com/google/gerrit/server/patch/PatchFile.java#56

Fixed with https://github.com/GerritCodeReview/gerrit/commit/689e240425f06b233c9641212af2a9a5fa0154ad

The fix has been released in v3.11.2, v3.10.5 and v3.9.10

We are on 3.10.6 now, so this is presumably fixed ?
