1265507 - Make repository "last modified" date more accurate

Status: RESOLVED FIXED

(Developer Services :: Mercurial: hg.mozilla.org, defect)

Description

[Gregory Szorc [:gps]]

The "last modified" date reported by the Mercurial web interface at e.g. https://hg.mozilla.org/ is based on the mtime of .hg/store/00changelog.i. When we stand up new servers, we perform a `hg clone` and the mtime of this file is the time we perform that clone. So, for the new hgweb[11-14] servers, "last modified" is being reported within the past few weeks.

We should have a script that can set the mtime of .hg/store/00changelog.i from either a) the mtime on the master server b) the time of the last push so the "last modified" date is more accurate.

There is a slight chance this could muck with repo freshness checking in Mercurial internals. But I'm pretty sure Mercurial compares equivalence of mtime values, not greater/less than comparisons (which are subject to clock skew and therefore not as reliable). So we should be good moving the mtime backwards.

scripts: add script to adjust mtime of repo from pushlog times (bug 1265507)

And deployed and executed in prod.

I also changed the "last modified" string to RFC 3339 so it is easier to read.
