This script and our CI scripts tools/travis/{backend,frontend} have
stayed pretty well in sync in the 6 months since 360c27ded made that
relationship explicit and easy to check!
Just one small exception; so fix that.
This may or may not be temporary, but either way, the other code is
there in source control, and the "why" of disabling gitlint is the
helpful bit for a comment.
Injecting the generated-file warning into the settings dict felt a
little unnecessarily magical. A warning like this is always going
to be at the top; the way it might differ between files is mainly
if the syntax for a comment varies, and in that case a simple
substitution like we're doing in this template wouldn't be enough
to express the difference anyway. So, embrace the hardcoding.
Now, the template and the images.yml entry have a very simple
relationship: the keys in one are exactly the keys in the other.
That's good for people quickly and confidently understanding it.
Now that the Markdown extension defined in
zerver/lib/bugdown/api_generate_examples depended on code in the
tools/lib/* directory, it caused the production tests to fail since
the tools/ directory wouldn't exist in a production environment.
This commit uses the Markdown extension defined in
zerver/lib/bugdown/api_generate_example to generate the example
fixture and code example, so that both are tested in
tools/lib/api_tests.
We don't disable code by commenting it out -- that leaves a mess.
We delete it. Remembering what the code was is what source control
is for.
This fixes cd849bc3f "test-run-dev: Disable Nagios check."
from a few weeks ago.
For now, this does nothing in a production environment, but it should
simplify the process of doing testing on the Thumbor implementation,
by integrating a lot of dependency management logic.
This commit also adds a tool to push translation sources to Transifex.
This tool makes sure that we don't push mobile source file. Mobile
source file is supposed to be handled from Zulip-Mobile repo.
(This is a small fixup to the main change, which was accidentally
included in a previous commit:
08bbd7e61 "settings: Slightly simplify EMAIL_BACKEND logic."
Oops. See there for most of the changes described here.)
The installer works out of a release-tarball tree. We typically want
to share this tree between successive test-install runs (with an rsync
or similar command to update source files of interest) because
rebuilding a release tree from scratch is slow. But the installer
will munge the tree; so instead of directly bind-mounting the tree
into the container, we need to give it an overlay over the tree, as a
sandbox to play in.
Previously we used lxc-copy's `-m overlay=...` feature to do this,
mounting an overlay in the container. But then sometimes in
development we want to reach in and edit some code in the tree,
e.g. before rerunning the installer after something failed. Reaching
inside the container for this is a pain (`ssh` would add latency, and
I haven't installed sshd in the containers; and getting rsync to work
with `lxc-attach` was beyond what I could figure out in a few minutes
of fiddling); and editing the base tree often doesn't work.
So, create the overlay with our own `mount -t overlay`, and have
`lxc-copy` just bind-mount that in. Now the host has direct access to
the same overlay which the guest is working from.
Also this makes it past time to help the user out in finding the fresh
names we've created: first the container, now this shared tree. Print
those at the end, rather than make the user scroll to the top and find
the right `set -x` line to copy-paste from.
This is the last commit in the series of commits for completing the
project of cleaning up our html templates to have 4 space and
valid indentation.
Fixes: #1236.
In this commit we also fix a test which would fail as a result of
doing this cleanup since the test wasn't designed to take into
account the space chars which might occur in the beginning of a
html line.
This test randomly fails far too often in Travis -- I think more than
all our other tests combined. It needs to be fixed before we can ask
everyone to look at build failures it causes.
Now that we have `eval_rst` and can explicitly exclude pages from the
toctree completely, we no longer need to set `includehidden`, and we
can return to using upstream's template.
(Meanwhile, our feature request upstream was successful! See
rtfd/sphinx_rtd_theme#485, which upstream implemented just a week
after we requested it. So that would have been another option.)
This reverts commit 11b8b8f48 "docs: Add rtd layout template."
It runs in kind of a peculiar environment -- in particular with the
`tags` identifier injected into the namespace -- and it contains
very little code more complex than `foo = "bar"`, so there's not
much to check anyway.
Before this fix, the installer has an extremely annoying bug where
when run inside a container with `lxc-attach`, when the installer
finishes, the `lxc-attach` just hangs and doesn't respond even to
C-c or C-z. The only way to get the terminal back is to root around
from some other terminal to find the PID and kill it; then run
something like `stty sane` to fix the messed-up terminal settings
left behind.
After bisecting pieces of the install script to locate which step
was causing the issue, it comes down to the `service camo restart`.
The comment here indicates that we knew about an annoying bug here
years ago, and just swept it under the rug by skipping this step
when in Travis. >_<
The issue can be reproduced by running simply `service camo restart`
under `lxc-attach` instead of the installer; or `service camo start`,
following a `service camo stop`. If `lxc-attach` is used to get an
interactive shell, these commands appear to work fine; but then when
that shell exits, the same hang appears. So, when we start camo
we're evidently leaving some kind of mess that entangles the daemon
with our shell.
Looking at the camo initscript where it starts the daemon, there's
not much code, and one flag jumps out as suspicious:
start-stop-daemon --start --quiet --pidfile $PIDFILE -bm \
--exec $DAEMON --no-close -c nobody --test > /dev/null 2>&1 \
|| return 1
start-stop-daemon --start --quiet --pidfile $PIDFILE -bm \
--no-close -c nobody --exec $DAEMON -- \
$DAEMON_ARGS >> /var/log/camo/camo.log 2>&1 \
|| return 2
What does `--no-close` do?
-C, --no-close
Do not close any file descriptor when forcing the daemon
into the background (since version 1.16.5). Used for
debugging purposes to see the process output, or to
redirect file descriptors to log the process output.
And in fact, looking in /proc/PID/fd while a hang is happening finds
that fd 0 on the camo daemon process, aka stdin, is connected to our
terminal.
So, stop that by denying the initscript our stdin in the first place.
This fixes the problem.
The Debian maintainer turns out to be "Zulip Debian Packaging Team",
at debian@zulip.com; so this package and its bugs are basically ours.
This is a tool that throws away `fsync` calls and other requests for
the system to sync files to disk. It may make the install faster; for
example, if it has to install a number of system packages, `dpkg` is
known to make a lot of `fsync` calls which slow things down
significantly. Conversely, if there's a power failure in the middle
of running a test install, we really don't mind if the test install's
data becomes corrupt.
When the install script is successful, one of the final things it
wants to do is to move the tree that Zulip was installed from into the
deployments directory. It can't do that, at least not in a naive way
with `mv`, if the tree is actually a mount point. So, stick the tree
inside some other directory that we create just for the purpose of
being the mount point and containing the install tree.
This saves several minutes off the install time. Sadly pip still
clones Git repos for dependencies that point to them, but for many
others (not all? not sure) it just gets a wheel from the cache.
The third-party `install-yarn.sh` script uses `curl`, and we invoke it
in `install-node`. So we need to install it as a dependency.
We've mostly gotten away with this because it's common for `curl` to
already be installed; but it isn't always.
This greatly simplifies iterating on changes to the installer and
associated code: just edit in the shared directory (or edit in your
worktree and rsync to the directory), and rerun.
With this change, the form with a directory is now really the main
way to run the script; the form accepting a tarball is really just
a convenience feature, unpacking the tarball and then proceeding with
that directory.
This will facilitate testing interesting installer features
using its own CLI.
On my laptop, with a recent base image (updated a few days ago with
`prepare-base`), it takes just 7 or 8 seconds to get to the installer
running, as timed by passing `--help` so that the installer promptly
exits.
