All, probably Jordi in particular,

The '@' bookmark on the default branch lags behind the actual tip of the
default branch very frequently in our repository.

For example, at the moment, '@' points to 2f6698dd7dad, but the latest
change on the default branch is ecb5688b875f, 28 changesets later.

Is there any way we can help developers who are pushing changesets on
the default branch to ensure that the '@' bookmark is advanced properly?

All of my workflows and continuous build scripts depend on the '@'
bookmark being up to date.

Separately, but relatedly, can someone tell me whether this is a
Mercurial bug or not?

    $ hg phase
    25345: public
    $ hg id
    2f6698dd7dad tip @
    $ hg pull -u -q
    $ hg id
    ecb5688b875f tip @
    $ hg log -r @ -T '{node|short}\n'
    ecb5688b875f
    $ hg book -d @
    $ hg pull -u -q
    $ hg log -r @ -T '{node|short}\n'
    2f6698dd7dad

In short, when the '@' bookmark is active and I pull and update, the '@'
bookmark is advanced, and it no longer agrees with what the server says
the '@' bookmark is. If I delete '@' and pull again, I get a different
answer. Seems wrong.

I updated the '@' bookmark to point to the tip on default.  It does occasionally happen when merging in a lot of changes that the '@' bookmark gets confused.  To restore it, I manually moved the bookmark (I was sitting on the tip of the development branch at the time) with

hg book -r . @
moving bookmark '@' forward from 2f6698dd7dad
hg update @
