In the web UI, eg pages like:

https://hg.mozilla.org/integration/autoland/rev/1467f14d7dd6bc82b4d445dd6505353069d005ff

The 40 digit hash/id of each revision should be shown. it's more useful to use with perfherder compare that way.

See Bug 1523385 Comment 1

I'm in favor of making this change! 👍

In case someone aside from me takes this bug, we will need to modify the Mercurial templates for gitweb_mozilla to change all instances of {node|short} to just {node}. We'll also need to add/modify the patch files in hgtemplates/.patches. This will likely also require a bunch of cosmetic test fixes to add the full hash to output.

I'll be taking care of this after we do the Mercurial 4.9 upgrade on hg.mo (sometime this week).

Treeherder has removed support for using 12 character revision
SHAs, due to the performance hit taken by being unable to fully
index a 12 character SHA (since the 40 character SHA is the
canonical version). This commit performs a global replace of
{node|short} with {node} for the gitweb_mozilla theme.

The existing form takes the node template keyword and passes
it through the short template filter, producing the 12-character
SHA. Removing the short filter will cause the full 40-char
SHA to be displayed instead.

Like all other templating changes, we add a patchfile to
hgtemplates/.patches that encompasses all the changes made by
this commit. Running hgserver/tests/test-template-sync.t
verified that the changes are successfully tracked under version
control.
