Since we need KaTeX to be available for zerver/lib/tex.py and
static/third/katex/cli.js to be able to shell out to it. However, for
some reason, the KaTeX we bundle using Webpack doesn't seem to be
importable by Node (and it's also kinda a pain to find its filename
from `cli.js`).
So, we work around this by just using the legacy system for KaTeX.
Something similar is needed for zxcvbn.js, in order to support the
settings_account.js use case (basically deferred loading of this
file); that requires JS code to have access to the correct path for
zxcvbn.
This implementation never worked, for two reasons:
(1) The logic for getting the path to the katex package had invalid
syntax in the version of Node we use.
(2) The KaTeX package bundled by webpack doesn't seem to be importable
from Node at all.
This allows us to selectively use some of the powerful features of
ReST which Python projects with high-quality documentation (like
Python core, and Django) rely on.
It's now January 2018, so we can delete this caveat, right?
Not quite yet -- the original post we link to now has an
update saying 2018-02-27. Let's make it less specific,
in case the date changes again.
Bulleted information instead of prose, huzzah! Also I think we need
to explain the options a bit right here, or at least link to where
they're documented somewhere. (If the list gets much longer, we'll
want to shift toward the latter.)
Also reorganize existing information a bit, and clean up a couple
of nits.
What I really want is to give these sections nice stable slugs
to put on the anchors and use as the URL fragment, independent of
any wording tweaks on the text headings. But I don't think we
have that feature with Markdown and our current docs infrastructure.
At least for Certbot, the brevity helps make this heading clearer
than the previous one.
Previously we had a problem of id clashes while importing converted
slack data into an existing zulip instance with realms which are actively
populating the database.
This counts the total objects to be imported and does a db transaction
to increase the SEQUENCE number for that table by that number,
and hence allocates a range of ids for the to be converted slack data
objects.
Adds a check for newline that was present on backend, but missing in the
frontend markdown implementation. Updating messages uses is_me_message flag
received from server instead of its own partial test. Similarly, rendering
previews uses markdown code.
Fixes#6493.
This is done by using a bot's ID instead of email in
the handler methods for bot_data.bots and bot_data.services,
and updating all code paths involved.
This is the first step for allowing users
to edit a bot's service entries, name the
outgoing webhook configuration entries. The
chosen data structures allow for a future
with multiple services per bot; right now,
only one service per bot is supported.
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.
