Our CSS checker globs for .css files. Since the
SCSS cutover, it has been a no-op, so there's no
sense launching it. See #8894 for details on
future plans.
This migrates Zulip to use a dramatically better set of names and
aliases for our emoji set, defined in emoji_names.py (which is in turn
manually generated from our hand-curated CSV file).
This should significantly improve the experience of using Zulip's
emoji picker and emoji typeahead for finding what one is looking for.
Credits to @rishig, Alice Lai, and @rntharu for naming all the emoji.
Names are inspired by iamcal, gemoji, and unicode names, sources like
emojipedia and iemoji, google search results for articles about emoji,
and emoji usage on twitter.
We were already correctly including libssl-dev in Zulip's dependencies
in development environment provisioning, but (at least now) it's
needed to build certain Python packages like pycurl when building a
Zulip virtualenv in production. I haven't investigated why we didn't
need this on Ubuntu, but one possible reason would be that some other
library in our dependencies list happens to depend on it on Ubuntu.
We fix this by moving the dependency over to the shared
VENV_DEPENDENCIES list.
Fixes part of #9946.
This will allow us to begin to add our own stubs for external
libraries. Writing stubs can be surprisingly little work to do, and
can have high leverage in keeping our type annotations high-quality.
This implements right-to-left message automatic detection support in
the compose box as well as the message feed. Full unit tests and
support in the message-editing UI are for future work (as are
potentially more fancy things like supporting things like
right-to-left multi-word names for users/streams/etc.).
Fixes#3123.
This will be helpful in the upcoming changes which will make use
of this extracted function to re-create zulip_test_template after
migrating zulip_test db so that we have latest schema in tests.
This commit fixes some modules that were erroneously left out while
transitioning app.js to webpack. This commit exposes them using
expose-loader or setting them directly to window.
This commit moves all files previously under the 'app' bundle in
the Django pipeline to being compiled by webpack under the 'app'
entry point. In the process, it moves assets under the app entry
to a file called app.js that consumes all relevant css and js files.
This commit also edits the webpack config to be able to expose certain
variables for third party libraries that are currently required by
some modules. This is bad coding form and should be refactored to
requiring whatever dependencies a module may have; we're just
deferring that to the future to simplify the series of transitions we
need to do here. The variable exposure is done using expose-loader in
webpack.
The app/index.html template is edited to override the newly introduced
'commonjs' block in the base template. This is done as a temporary
measure so as not to disrupt other pages on the app during the transition.
It also fixes the value of the 'this' context that was being inferred
as window by third party libraries. This is done using imports-loader
in the webpack config. This is also messy and probably isn't how we
want things to work long term.
The only changes visible at the AST level, checked using
https://github.com/asottile/astpretty, are
zerver/lib/test_fixtures.py:
'\x1b\\[(1|0)m' ↦ '\\x1b\\[(1|0)m'
'\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n'
which is fine because re treats '\\x1b' and '\\n' the same way as
'\x1b' and '\n'.

Adds search_pill.js to the static asset pipeline. The items
for search pill contain 2 keys, display_value and search_string.
Adding all the operator information i.e the operator, operand and
negated fields along with the search_string and description was tried out.
It was dropped because it didn't provide any advantage as one had to
always calculate the search_string and the description from the operator.
The appropriate name for the remote pointing at the repo we maintain
may be `upstream` for most of our repos... but not when we're
downstream of someone else, e.g. for react-native. So, make it easy
to configure per-repo.
This results in a significant optimization in the performance of
re-provisioning Zulip if all that you're doing is rebasing onto a
newer version of master (which just adds new migrations).
The change carries some risk of generating unpleasant-to-debug
situations, because if we merge a buggy migration and then later fix
it, some clients may not have a properly migrated database (and also,
this changes how populate_db commutes with migrations). But it seems
worth it, given how much time is currently wasted by not having this.
Fixes: #9512.
In this commit we are adding run_generate_fixtures_if_required,
a new function which is meant to de-duplicate a bit of code
between test-server and test-backend which is essentially
responsible for rebuilding the test database if that was required.
In this commit we are essentially just refactoring the function
is_template_database_current to be called template_database_status
and adjusting the return values accordingly.
This is essentially a preparatory commit for the upcoming commits
which will essentially enable us to not throw away entire DB and
rebuild from scratch if only running migrations could do the job.
This should avoid us creating duplicate webpack bundles every time we
do a deployment, even if none of the files in the bundles themselves
have changed at all.
This option (aka `--raw-output`) prints a string as itself, rather
than JSON-encoded; which makes it fit a bit better in a shell script,
saving us a layer of quoting.
This replaces ad4617c95 with a different fix for the same issue:
instead of stripping the `.git` off separately, we can just correct
the regex, using `+?` to fix our stepping in a classic regex pitfall.
This is a performance optimization: Rather than copying these files
into the `prod-static` directory and then deleting them, we just don't
copy them over in the first place.
For styles, it might have once been the case that this did something,
but we've moved them all to being managed by webpack some time ago.
For the js directory, I think it was never useful to copy and then
delete them; these files were always compiled via tools/minify-js,
and the raw JS files weren't needed, anyway.
This changes run-dev.py to ensure that we have in fact compiled
handlebars templates before running webpack, which is the right model.
Future work will likely include running the handlebars compiler from
webpack, and thus eliminating this extra process.
This improves the performance of these operations, by saving a ~50ms
Python process startup. While not a major performance improvement, it
seems worth it, given how often these commands get run.
Fixes#9571.
First, it's silly that these weren't in common.css in the first place,
since that meant these were a bunch of duplicated code, but
additionally, that meant that these weren't available on the
`/activity` page (or other pages that don't include the portico styles).
Fixes#9561.
Makes the i18n strings in this file much easier to translate by splitting
them into smaller chunks (which avoids having a lot of code in the tagged
strings), and adds a string that was missing as well.
We fix the issue of check-templates spitting out diff between
expected and found indentation of a file before mentioning the
error message and the file name. Basically stuff was being in the
wrong order despite the fact that in code stuff was happening in the
correct order ie, first print the error message along with the filename
and then the actual diff between expected and found file indentation.
Fixes: #9533.
A "zform" knows how to render data that follows our
schema for widget messages with form elements like
buttons and choices.
This code won't be triggered until a subsequent
server-side commit takes widget_content from
API callers such as the trivial chat bot and
creates submessages for us.
This starts the concept of a schema checker, similar to
zerver/lib/validator.py on the server. We can use this
to validate incoming data. Our server should filter most
of our incoming data, but it's useful to have client-side
checking to defend against things like upgrade
regressions (i.e. what if we change the name of the field
on the server side without updating all client uses).
I mistakenly pushed a PR when my tests failed. I ran with
the coverage option, so I saw this brightly colored summary
report that distracted me from the failure message.
This adds a couple newlines and some all caps.
The timezone environment variable was set to UTC initially. It was
changed to something other than UTC so that any local vs UTC
conversion issues will manifest in the tests.
Fixes: #5105.
We essentially stop running create_realm_internal_bots during
every provisioing and move its operations to run from populate db.
In fact to speed things up a bit we actually make populate db call the
funcs which create_realm_internal_bots calls behind the scenes.
Fixes: #9467.
This is required because the --settings=zproject.test_settings param
doesn't work with migrate or the dumpdata management commands. Thus
untill now if one ran just this tool ended up with test database not
properly setup. We never noticed this because test-backend ran this
tool again (after exporting DJANGO_SETTINGS_MODULE) thus making the
tool work this time.
I've often done this by hand -- basically typed out the last line,
with the variables found from looking at the PR page in a browser.
Seems nicer for both us maintainers and the contributor, in particular
because the PR gets marked as merged, instead of closed. But it's a
bit of a pain, and I do it maybe half the time or less; plus it's kind
of a subtle GitHub feature, and as a result I think other maintainers
of Zulip repos do this approximately never.
I've always figured this couldn't be hard to automate; today I decided
to take the 45 minutes to look up how, write out the script, QA it,
write up a nice usage message and some comments, and commit it. :)
This commit improves the output that blueslip produces while
showing error stack traces on the front-end. This is done by
using a library called error-stack-parser to format the stack
traces.
This commit also edits the webpack config to use a different
devtool setting since the previous one did not support sourcemaps
within stack traces. It also removes a plugin that was obviated
by this change.
This improves test coverage for a lot of our webhooks that relied
on ad-hoc methods to handle unexpected event types.
Note that I have deliberately skipped github_legacy, it isn't
advertised and is officially deprecated.
Also, I have refrained from making further changes to Trello, I
believe further improvements to test coverage should be covered
in separate per-webhook commits/PRs.
UnexpectedWebhookEventType is a generic exception that we may
now raise when we encounter a webhook event that is new or one
that we simply aren't aware of.
Now that we have tsearch_extras packages uploaded, this mostly works.
There's a few issues being debugged in #9460; they should be fixed
soon, and regardless, merging this will make it easier to develop.
This makes it possible to again use the *.zulipdev.com domains in the
development environment.
Ideally, we'd also read REALM_HOSTS to make this more flexible.
This adds a tour of Zulip to the bottom of the homepage.
In order to get the carousel nave, we use Bootstrap 2 from a CDN on
this page; this isn't ideal in the medium term, but upgrading
Bootstrap across the project is too much work for now.
Apparently, we were incorrectly appending each new hash onto the end
of the file, basically resulting in every run of provision being
treated as a miss for this cache.
Fixing this saves about 4s (over 1/3) of the no-op provision time.
Fixes#9233.
Uses nargs='*' instead of nargs='argparse.REMAINDER'.
nargs='argparse.REMAINDER' gathers remaining terms as arguments
even if it is an option e.g --coverage, while '*' gathers all the
command-line arguments until the next option is encountered.
The only slash command implemented in this initial
version is an extremely crippled version of a
"/stats" slash command that reports that you are
running 1 server.
This has a cool structure, but it's written against the long-dead
South API, and we can always pull it out of the Git history if we want
to use this approach in the future.
This leaves the wrapper script with very little left to do!
The main thing left is finding scripts by searching for shebang lines;
mypy itself would happily do the search for importable Python files.
Cleaned up add_user_list_args(). The "help" and
"all_users_help" have all default values. As noted in
an earlier commit, "all_users_help" is always passed in,
so we can get rid of "all_users_arg". We keep the default
for "all_users_help" so we don't have to change variable order
in function definition.
Since the region of base.zulipdev.org is
NYC3 we had to add SFO1 as an additional
region each time a snapshot of base droplet
is created. This is required as droplets
can be created in SFO1 only if there is
an image present in that region. Adding
of droplet image to SFO1 takes a lot of
time as well as cost 2X as we are storing
2 images. It's better to just create new
droplets in NYC3 instead. Alternatively we
can create a new base droplet in SFO1 if
we want all the droplets to be created in
SFO1.
This puts all of this config in one place, and also needs a lot fewer
lines to describe it; which, combined, makes it a lot clearer what our
normal config actually is. (I'd been looking at this script for a few
minutes without realizing that we have `--disallow-untyped-defs` *on*
by default, not off.)
Experimenting with different values is still easy; just comment the
line in the config.
This commit moves the stylesheets under the archive bundle in
the Django pipeline to being compiled by webpack instead. It
also removes a remaining call to a portico stylesheet that no
longer exists.
This commit transitions landing-page.css from the Django pipeline
to being compiled by webpack as landing-page.scss under the
'landing-page' and 'integration' bundles.
This commit transitions all styles in app.css in the Django pipeline
to being compiled by webpack in an app-styles bundle, and renames the
various files to now be processed as SCSS.
To implement this transition, we move the old CSS file refernces in
settings.py and replace them with a bundle declared in
`webpack.assets.json` and includedn in the index.html template
Tweaked by tabbott to keep the list of files in `app.css` in
`webpack.assets.json`, and to preserve the ordering from the old
`settings.py`.
This commit removes the flash on unstyled content while in dev
mode that was caused by the use of style-loader. Instead it
enables mini-css-extract-plugin in dev in combination with
css-hot-loader which enables HMR for development.
This is because mini-css-extract-plugin does not currently support
HMR out of the box. It also adds a SourceMapDevtoolPlugin to enable
sourcemaps with css since mini-css breaks sourcemaps when used in
combination with the cheap-module-evel-source-map setting.
Related issues:
https://github.com/webpack-contrib/mini-css-extract-plugin/issues/34https://github.com/webpack-contrib/mini-css-extract-plugin/issues/29
We modify check-templates to check for duplicate id's in archive
templates and app templates separately. This means we are allowing
app and archive templates to potentially use same id's. This is
needed because we intend to re use some js from the main app and
having same id's help achieve that.
Note: We haven't up until this point actually added archive
templates. This commit is more of a preparatory commit for merging
the basic archive infra.
Adds support for importing png files using file-loader in webpack.
Changes the name of the output directory to be files instead of
fonts for better readability.
This commit removes the need for portico.css to be generated
by the Django pipeline and makes the error page use the css
file compiled by webpack instead.
Combines, both portico js and css into one bundle. This for now solve
the issue of an empty js bundle being generated by webpack for the
portico-styles stylesheet.
This was a bit more than moving code. I extracted the
following things:
$widget (and three helper methods)
$input
text()
empty()
expand_column
close_widget
activity.clear_highlight
There was a minor bug before this commit, where we were inconsistent
about trimming spaces. The introduction of text() and empty() should
prevent bugs where users type the space bar into search.
This commit adds a --quiet argument to tools/webpack which removes
the verbose output from webpack and replaces it with showing only
errors. It also makes tools/run-dev --tests use this argument while
running webpack for testing.
Tweaked by tabbott to clean up the code a bit.
static/styles/scss/portico.scss is now compiled by webpack
and supports SCSS syntax.
Changed the server-side templates to render the portico-styles
bundle instead of directly requiring the portico stylesheet. This
allows webpack to handle stylesheet compilation and minification.
We use the mini-css-extract-plugin to extract out css from the
includes in webpack and let webpacks production mode handle
minification. Currently we're not able to use it for dev mode
because it does not support HMR so we use style-loader instead.
Once the plugin supports HMR we can go on to use it for both
dev and prod.
The downside of this is that when reloading pages in the development
environment, there's an annoying flash of unstyled content :(.
It is now possible to make a change in any of the styles included
by static/styles/scss/portico.scss and see the code reload live
in the browser. This is because style-loader which we currently
use has the module.accept code built-in.
This commit fixes hot module replacement in webpack. To do this
we open port 9994 used by webpack to communicate between browser
and devserver. The attempts to forward the proxy from 9991 failed
so the last resort was to open up the webpack port.
It also removes an uncessary plugin in the webpack config and moves
the --hot flag to tools/webpack.
We've already got a bunch of other comments on work we need to do for
this decorator and an open issue that will ensure we at some point
rework this and add tests for it. In the meantime, I'd like to lock
down the rest of decorator.py at 100% coverage.
Fixes#1000.
Webpack dev server by default does host checking for requests. so
in dev enviorment if the the request came for zulipdev.com it would not
send js files which caused dev envoirment to not work.
This should make it easier to find the templates that are actually
part of the core webapp, instead of having them all mixed together
with the portico pages.
Update the config file to show slightly more information while
compiling webpack. Also decreased the time webpack waits before
recompiling in order to speed up HMR.
Changed the devtoool setting for development from 'eval' to
'cheap-module-eval-source-map' as it has better support for
breakpoints in Google Chrome and the difference is time is
negligible at the number and size of files currently being
consumed by webpack. This stragtegy can be reviewed in the
future as the size of files grows or Chrome adds better
support.
Upgrade webpack to latest version at the time of authoring. This
involves upgrading webpack version and its loaders to compatible
versions. It also involved editing tools/webpack to use the
executable for webpack-cli instead because of a change in how the
webpack package wants you to handle shell execution.
It also fixes the confugration for TypeScript in the webpack config
as that was previously broken. Including TypeScript files in JS
files compiled by webpack now works.
This prevents us from using const in our JS code, with exceptions
for test code and the portico. Hopefully this is just a temporary
rule until we make our pipelines with work with ES6.
I tried to prevent "let", but that was too noisy.
This adjusts the one false-negative case of using const in a comment.
We now allow you to run --coverage on individual files. This helps
when you want to make sure a file is being covered directly and not
just getting incidental coverage from higher level tests.
Before this commit, we were conflating wanting coverage reports with
wanting coverage checks. For individual files, we now solve that by
simply eliminating the coverage checks. This required some minor
refactoring to extract some functions.
This fixes a bug where provision was failing since our most recent
upgrade to yarn/nvm/node.
It turns out my original fix was the correct fix, but to the wrong
third-party tool: nvm, not yarn, was the offender.
String.prototype.endsWith is not supported in ie11.
Adds string.prototype.endswith package to dependencies and places
it at `common` entry point in webpack.assets.json.
Fixes#8944.
Adds string.prototype.startswith package to dependencies and places
it at `common` entry point in webpack.assets.json. As common.js is
loaded on all code paths first, there is no need to place this package
into other entry points.
We make some specific cases of tags use 2 space indents.
The case description:
* A tag with opening tag spread over multiple lines and closing tag
on the same line as of the closing angle bracket of the opening tag.
* A tag with opening tag spread over multiple lines and closing tag
not on the same line as of the closing angle bracket of the opening
tag.
Example:
Case 1:
Not linted:
<button type="button"
class="btn btn-primary btn-small">{{t "Yes" }}</button>
After linting:
<button type="button"
class="btn btn-primary btn-small">{{t "Yes" }}</button>
Case 2:
Before linting:
<div class = "foo"
id = "bar"
role = "whatever">
{{ bla }}
</div>
After linting:
<div class = "foo"
id = "bar"
role = "whatever">
{{ bla }}
</div>
After some thinking, I don't think there's any actual value to doing
the ../ style relative links here, whereas there is actual harm from
the links being slightly broken in the current model. We fix this by
just using /#settings as the URL.
Fixes#8978.
Added support for passing a filename without `.js` suffix.
This then fixed the issue of no complaints for invalid test
files. Now, throws an error for invalid test files.
Fixes#8579.
Update perfect-scrollbar to fix stutter space-scrolling in #8544. Also
reworked deprecated `element.perfectScrollbar` to `new
PerfectScrollbar(element)`. Lastly, updated provision version and
changed node module path to new path.
This also refactors perfect-scrollbar in help.js to work with updated
version of perfect-scrollbar. Because the update also changed
perfect-scrollbar's css selectors for all scrollbars in zulip, we
update those too.
Fixes#8544.
Namely, annotate as best as possible, and add notes to indicate preference,
if QuerySet develops generic typing.
Note that the return values of functions with annotations changed in this
commit are used elsewhere as QuerySets, so the Sequence[T] approach used
for some functions in models.py is not applicable.
Other functions took the form of returning Sequence[T] when the QuerySet
functionality is unused beyond the function, with T being the objects
filtered for in the function body; this commit follows that practice for the
one remaining python2 comment-annotated function, completing the transition
of models.py to py3.5 function annotations.
A note is also added to another function regarding a need to return a
QuerySet, and ideally a QuerySet[T] in line with the other functions, as and
when QuerySet becomes annotated as a generic.
This commit switches our emoji infrastructure to use 256 color indexed
64px spritesheets. Earlier we were using non-indexed 32px spritesheets
which were blurry on high dpi displays. These indexed spritesheets not
only provide a crispier display but are also smaller in size.
This commit also removes the `emoji-datasource` package as a dependency
as all the data is now sourced from individual datasource packages.
Fixes: #7862.
Main exceptions are scripts/tools/puppet & tests.
Other current exclusions:
- api_test_helpers.py (avoid changing test code);
- cache.py, due to comments in file;
- models.py, due to failure on QuerySet[Message];
- stream_subscription.py, due to failure on QuerySet[Subscription];
- tornado/descriptors.py;
- views/streams.py, due to remaining FuncKwargPair issue;
- zthumbor/, since thumbor is in python2.
Tweaked by tabbott to partially document the stauts in comments.
This flips the experimental `--express` option to be the default.
We retain the old behavior, where the script exits before
`initialize-database`, as an option `--no-init-db`; it might be useful
in e.g. a migration scenario (from a Zulip install elsewhere, or
another chat system) where the admin wants to set up the database
separately.
The install instructions are adjusted to match, getting shorter by two
steps and a bunch of words. I think this opens up opportunities to
refactor the text to simplify things further, too, but leaving that
for another commit.
Also tweak the "production" test suite to match.
This replaces the cumbersome system we had for giving users feedback
on settings state changes in the display settings UI.
We expect this new system to be what we will attempt to migrate other
settings widgets to match over the coming weeks and months. It also
provides the opportunity to significant refactor away a lot of the
code duplication in settings_display.js.
Thanks to Brock Whittaker for redoing the styling and improving the
code simplicity.
Fixes#7622.
These two classes are tricky to test, and nocoverage-ing them
allows us to mark queue_processors.py as fully covered. We
still want to cover these two workers at some point, but for
now, it's nice to enforce full coverage for any future changes
to queue_processors.py.
Fixes (sort of) #6542.
This should help prevent against bugs where we accidentally introduce
use of sudo somewhere in the production installer or upgrade code path
(these used to happen all the time), which doesn't work on production
systems that don't have sudo setup.
Revert c8f034e9a "queue: Remove missedmessage_email_senders code."
As the comment in the code says, it ensures a smooth upgrade path
from 1.7.x; we can delete it in master after 1.8.0 is released.
The removal commit was merged early due to a communication failure.
This commit adds tests for the fixture for when a user is not
authorized (perhaps because the query requires the use of admin
privileges) for a particular query.
In templates/zerver/api/update-message.md, we have a sample fixture
for when a zulip.Client does not have the permission to update/edit
a particular message. This commit adds a test for that fixture.
Also, tools/test-api now also uses a non-admin client for this test,
which might come in handy in the future.
We now isolate the code to transmit messages into transmit.js.
It is stable code that most folks doing UI work in compose.js don't
care about the details of, so it's just clutter there. Also, we may
soon have other widgets than the compose box that send messages.
This change mostly preserves test coverage, although in some cases
we stub at a higher level for the compose path (this is a good thing).
Extracting out transmit.js allows us to lock down 100% coverage on that
file.
In this commit we add support for some tags which are also called
void-elements according to
http://w3c.github.io/html/syntax.html#void-elements to be parsed by
our template parser and get tagged as singleton_html_tags.
Fixes: #8387.
Now executable! Just run `tools/tagmessages`.
Also, get the username and password from a `.transifexrc` file.
And hardcode the project slug to `zulip-test` rather than to `zulip`;
the Transifex API is bad at namespacing, so this makes it possible to
run this script on a test project (the only way we're currently using
it) even for people like me who can also upload to the real Zulip
project on Transifex.
We now have a separate page for common error payloads, for example,
the payload for when the client's API key is invalid. All error
payloads that are presented on this page will be tested similarly
to our other non-error sample fixtures.
Otherwise prepare-base is likely to fail when first run (but then
succeed when rerun, because the container is left running), because
the container isn't up yet when we try to operate in it.
Also clean up the placement of `set -e` vs `set -x`.
Apparently, we've now had the first time one of our contributors had
their account deleted (at least, the author page for the contributor
who has 21 commits in python-zulip-api now 404s).
See 625939 for more information. In short, the purpose of this delay is
to give autoreload code enough time to touch every watched file at least
once before the change is made.
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.
