These commands are super boring standard Docker commands,
so this probably isn't helpful for anyone who is familiar
with building Docker images... but I had to consult docs
to work out the right commands again today, so they'd help me.
This new base image just comes from me doing a fresh `docker build`
and uploading the result. That gives it fresher versions of our
APT dependencies than the image I built a couple of months ago,
speeding up provision by giving it less to install.
Provision was failing at tools/setup/postgres-init-dev-db
with this in the log:
Sep 20 02:27:01 + sudo -i -u postgres psql ''
[sudo] password for circleci:
The issue is that the old version of this line (from Circle upstream)
only lets the `circleci` user sudo to root -- not to other users, or
not directly anyway -- because sudoers syntax is complicated. Fix it,
after studying `man sudoers`.
This is only an optimization -- if this list is missing anything,
we'll get to it in `provision` in the actual build. That's important,
because we want an existing image to work fine for testing new
versions of our codebase, including changes that may install more
packages in `provision`.
What this does accomplish is keeping provision's `apt-get install`
fast, by leaving it very little work to do.
The list comes from looking at the APT output during provision in an
actual run without this step, and leaving out two packages which
aren't available at this stage, because we get them from PPAs:
postgresql-9.3-pgroonga and postgresql-9.3-tsearch-extras.
Install `jq` with APT -- that's a lot simpler to read than this
explicit download.
And coalesce several commands, following Docker upstream's
recommendation and avoiding unnecessary overhead.
From just my experience attempting this change, I've been impressed
with the very fast turnaround in CircleCI for a change -- from `git
push` to the build starting is usually just a couple of seconds.
It also looks like we get much clearer control over the caching
system, and the setup of the environment via a Docker image of our
choice, which can help avoid most of the several minutes Travis takes
to set up our environment before it actually starts running the tests
themselves.
Plus it supports fine-grained parallelism, e.g. by test file:
https://circleci.com/docs/2.0/parallelism-faster-jobs/
So we can probably get much faster builds by making this switch.
Because the environment is much more transparent and even under
our control, I'm also hopeful for more reliable builds.
This is nearly the same as Circle's version, linked in the comment.
I've
* changed the FROM line to get Ubuntu,
* added a couple of distro packages to compensate, and
* revised the comments.
Substantively, this makes the table more readable by grouping users
into expanding sets by level of activity: active in last day, active
in last week, have an account at all. The class "active in last week",
as opposed to "active in last week but not in last day", makes more
natural comparisons both between realms and for one realm through time,
and it's less sensitive to the details of our definitions.
This also makes the terminology more standard. We already made that
change in the display, in the previous commit; as we go through the
logic here, we adjust the terminology in the code too.
This seems to have been causing the travis production suite to fail.
It's a direct consequence of removing travis' giant library of apt
sources.list files; now that those are gone, there aren't copies of
all these extra packages available anyway.
This makes the typeaheads dark-mode compatible by changing to the
background to be dark and the text to inherit from the body text
(rather than bootstrap’s default of #333).
The streams can be light and if it inherits the white text color they
will not be readable. It should default to dark text with the exception
of when the tab is is `.dark-background`, in which case then it should
revert to inheriting the white color.
This makes the edit history overlay dark mode compatible by changing
the background to the dark blue along with changing the highlight
colors to work with white text and dark backgrounds.
