This makes a small improvement to 'cold cache' ember-cli build times, and a large improvement to 'warm cache' build times
The ember-auto-import update means that vendor is now split into multiple files for efficiency. These are named `chunk.*`, and should be included immediately after the `vendor.js` file. This commit also updates the rails app to render script tags for these chunks.
This change was previously merged, and caused memory-related errors on RAM-constrained machines. This was because Webpack 5 switches from multiple worker processes to a single multi-threaded process. This meant that it was hitting node's default heap size limit (~500mb on a 1GB RAM server). Discourse's standard install procedure recommends adding 2GB swap to 1GB-RAM machines, so we can afford to override's Node's default via the `--max-old-space-size` flag.
Allows to write custom code blocks:
```
```mermaid height=200,foo=bar
test
```
```
Which will then get converted to:
```
<pre data-code-wrap="mermaid" data-code-height="200" data-code-foo="bar">
<code class="lang-nohighlight">
test
</code>
</pre>
```
This reverts commit f4c6a61855 and a8325c9016
This update of ember-auto-import and webpack causes significantly higher memory use during rebuilds. This made ember-cli totally unusable on 1GB RAM / 2GB swap environments. We don't have a specific need for this upgrade right now, so reverting for now.

This commit adds a requestCustomMarkdownCookFunction function
to the `helper` that is provided to custom markdown rules
via their `setup` function.
The way this works is that once the default markdown engine that
we use for cooking posts has been set up, we loop through all
of the callbacks registered by `requestCustomMarkdownCookFunction`
and call `_buildCustomMarkdownCookFunction`. This creates
a new markdown engine using many of the same settings as the
default one, but will allow for the following options to be
changed by the markdown rule requesting the custom function:
* featuresOverride - The markdown-it features to allow for the engine
* markdownItRules - The markdown-it rules to allow for the engine
After this engine is set up a render function which renders + sanitizes
the output is returned for use by the markdown rule.
The use case for this API is mainly for block BBCode markdown rules
which want to render their content with a limited subset of the
markdown features/rules. Our initial use case for this is chat message
quoting.
This commit also does some minor refactoring of discourse-markdown-it
to accommodate this new engine building.
Sometimes plugins need to have additional data or options available
when rendering custom markdown features/rules that are not available
on the default opts.discourse object. These additional options should
be namespaced to the plugin adding them.
```
Site.markdown_additional_options["chat"] = { limited_pretty_text_markdown_rules: [] }
```
These are passed down to markdown rules on opts.discourse.additionalOptions.
The main motivation for adding this is the chat plugin, which currently stores
chat_pretty_text_features and chat_pretty_text_markdown_rules on
the Site object via additions to the serializer, and the Site object is
not accessible to import via markdown rules (either through
Site.current() or through container.lookup). So, to have this working
for both front + backend code, we need to attach these additional options
from the Site object onto the markdown options object.
Previously only `<div>one top element</div>` was allowed because we use `firstChild` instead of `children`.
We also want `<div>one</div><div>two</div>` to work with this method.
This commit extends the options which can be passed to
`PrettyText.markdown` so that which Markdown-it rules and Discourse
Markdown plugins to be used when rendering a text can be customizable.
Currently, this extension is mainly used by plugins.
Watched words of type 'replace' or 'link' replaced the text inside
mentions or hashtags too, which broke these. These types of watched
words must skip any match that has an @ or # before it.
We rely on yarn workspaces so we don't want people using npm in the repo by accident.
Also updated the required node version to 12+.
~~Not sure about the min yarn version – the latest one could be missing in various CI-like envs, so I might change it yet.~~
Downgraded yarn to ">= 1.21.1" (the oldest of "current" versions, tagged "legacy")
The generated regular expressions did not contain \b which matched
every text that contained the word, even if it was only a substring of
a word.
For example, if "art" was a watched word a post containing word
"artist" matched.
It was not clear that replace watched words can be used to replace text
with URLs. This introduces a new watched word type that makes it easier
to understand.
1. It defaults to `cache: true` already
2. Setting it to `false` for non-GET request doesn't do anything
3. We were correcting `cache: false` GET requests to use `cache: true`
…so setting it to anything at all, for any type of request doesn't make sense (anymore)
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change
- comments
- test descriptions
- other low risk areas
Watched words are always regular expressions, despite watched_words_
_regular_expressions being enabled or not. Internally, wildcard
characters are replaced with a regular expression that matches any non
whitespace character.
* FIX: Cache missing inline oneboxes
Some inline oneboxes were not cached when the server did not return an
answer for an URL and the queried URL and the absolute URL were
different.
For example, if user typed www.example.com, the client asked the server
for http://www.example.com and if the server returned an empty response,
then the client would keep requesting an inline onebox everytime the
composer changed.
In other words, the key used for reading (the absolute URL) and the one
used for writing (the URL as typed by the user) were not the same when
the server returned an empty response.
* DEV: Check cache before making request
There is another cache check in PrettyText, but that is not enough if
multiple requests are pending. This problem was made obvious in tests,
but can happen for users with slow connections.
