Syntax highlighting is a CPU-intensive process which we run a lot while rendering posts and while using the composer preview. Moving it to a background worker releases the main thread to the browser, which makes the UX much smoother.
Considering document length in search introduced too much variance in
our search results such that it makes certain searches better but at the
same time made certain searches worst. Instead, we want to have a more
determistic way of ranking search so that it is easier to reason about
why a post is rank higher in search than another.
The long term plan to tackle repeated terms is to restrict the number of
positions for a given lexeme in our search index.
```
discourse_development=# SELECT alias, lexemes FROM TS_DEBUG('www.discourse.org');
alias | lexemes
-------+---------------------
host | {www.discourse.org}
discourse_development=# SELECT TO_TSVECTOR('www.discourse.org');
to_tsvector
-----------------------
'www.discourse.org':1
```
Given the above lexeme, we will inject additional lexeme by splitting
the host on `.`. The actual tsvector stored will look something like
```
tsvector
---------------------------------------
'discourse':1 'discourse.org':1 'org':1 'www':1 'www.discourse.org':1
```
* Do not autofocus name input on mobile
* Improve code for formatted reminder type times to not be computed, so the modal times update correctly
* Change wording of "Next Monday" to "Monday" for all days except when today is Monday
Category and tag hashtags used to be handled differently even though
most of the code was very similar. This design was the root cause of
multiple issues related to hashtags.
This commit reduces the number of requests (just one and debounced
better), removes the use of CSS classes which marked resolved hashtags,
simplifies a lot of the code as there is a single source of truth and
previous race condition fixes are now useless.
It also includes a very minor security fix which let unauthorized users
to guess hidden tags.
* strip out the href and xlink:href attributes from use element that
are _not_ anchors in svgs which can be used for XSS
* adding the content-disposition: attachment ensures that
uploaded SVGs cannot be opened and executed using the XSS exploit.
svgs embedded using an img tag do not suffer from the same exploit
`Nokogiri::HTML.fragment` is a huge hack (a comment in the source code
admits this). The current behavior of `Email::Styles` is to try to
emulate `fragment` using nokogumbo, but it misses some edge cases. In
particular, meta tags in a email template don't make it through to the
final email.
Instead of treating the provided HTML as an indeterminate fragment, this
commit makes `Email::Styles` treat the HTML as a complete document. This
means that the generated HTML for an email will now always contain top
level structure (a doctype, html, head and body tags).
This new behavior is behind a hidden site setting for now and defaults
off.
Previously we would include this section, unfortunately
1. It is usually elided in gmail
2. It can make the emails longer and more confusing
3. Omission is a feature, it means people need to visit site to get context
There is a feature in search where we take over from the tokenizer
in postgres and attempt to inject more words into search.
So for example: sam.i.am will inject the words i and am.
This is not ideal cause there are many edge cases and this can
cause extreme index bloat.
This is an opening move commit to make it configurable, over the
next few weeks we will evaluate and decide if we disable this by
default or simply remove.
The admin permalink list was a little tricky to use because the URLs are easily reduced with a ... if they are too long. This adds a copy to clipboard button for the URL and a title on hover so the full text of the URL can be seen.
* FEATURE: Don't display muted/ignored users under "who liked"
Previously, if you clicked on the heart icon below a post
it would show you the avatar for a user even if you ignored or muted
them.
This commit will instead display a (?) icon. The count of likes will
remain correct, but you needn't be reminded of the person you
preferred not to see.
* Use a circle instead of (?) for unknown user
If people wish to opt out they can use `DISABLE_BOOTSNAP = 1`
Bootsnap is production ready and was tested on our production
servers for safety.
Promoting it now so it is enabled globally.
Will result in faster application boot
Adds new hidden site settings for rate limits:
30 for logged in users, 15 for anon
Adds an anon cache for searching, caches results of searches for 1 minute
Discourse needs a bunch of data preloaded before it can start up.
Normally we throw blobs of this into the HTML document that is requested
but in some cases that's awkward to retrieve.
For example with Ember CLI you have a separate javascript application
that needs to make its own HTML.
This API endpoint returns a JSON object with all the data Discourse needs to
bootstrap and start up.
Bootsnap is designed to work in production per:
https://github.com/Shopify/bootsnap
Over the years we have seen very few issues with it, none of which
were corruption.
This allows us to enable bootsnap in production
Having bootsnap enabled means that we can speed up deploys by
about 5 seconds per server. It also means a lot less waiting for
various production rake tasks and so on.
In some restricted setups all JS payloads need tight control.
This setting bans admins from making changes to JS on the site and
requires all themes be whitelisted to be used.
There are edge cases we still need to work through in this mode
hence this is still not supported in production and experimental.
Use an example like this to enable:
`DISCOURSE_WHITELISTED_THEME_REPOS="https://repo.com/repo.git,https://repo.com/repo2.git"`
By default this feature is not enabled and no changes are made.
One exception is that default theme id was missing a security check
this was added for correctness.
The risk here is that the database for one site goes down in the multisite setup and we drop everything to readonly mode. However, I discussed this with Sam and we agree that one database having problem is very rare. Most of the time, it is the entire DB cluster that goes down.
* FEATURE: notify admins about old credentials
Security and API keys should be renewed periodically.
This additional notification should help admins keep their Discourse safe and secure.
* DEV: To be pedantic, there is more than EMBER in there now
* DEV: Use less globals. Have `Discourse` start in an initializer
* DEV: Remove another global
It might happen that some User records have no associated primary emails.
In which case we don't ever want to send them a digest.
Also added a new "user_email_no_email" skipped email log to ensure these cases
are properly handled and surfaced.
* FEATURE: notify admins about old credentials
Security and API keys should be renewed periodically.
This additional notification should help admins keep their Discourse safe and secure.
This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
Adds a new topic_excerpt_maxlength site setting.
* When topic excerpt is requested for a post, use the new topic_excerpt_maxlength site setting to limit the size of the excerpt
* Remove code for getting/setting Post.excerpt_size as it is not used anywhere
* FIX: Emit web hooks for flags
* FEATURE: Remove 'flag' web hook in favor of 'reviewable' web hook
* FEATURE: Remove 'queued post' web hook in favor of 'reviewable' web hook
* FIX: Do not set a default value for web hooks with no events
This is so that, on a multisite cluster, when we handle a CDN request,
the hostname that is requested corresponds to one of the sites -
specifically the default site.
1. Total 6 attempts per day per user
2. Total of 5 per unique email/login that is not found per hour
3. If an admin blocks an IP that IP can not request a reset
Upgrades Rails to latest, this version has better compatibility
with Ruby 2.7
During the upgrade we needed a new cleaner mechanism for configuring
message bus.
All tests are green.
If anything weird pops up please revert.
We now show an options gear icon next to the bookmark name.
When expanded we show the "delete bookmark when reminder sent" option. The value of this checkbox is saved in local storage for the user.
If this is ticked, when a reminder is sent for the bookmark the bookmark itself is deleted. This is so people can use the reminder functionality by itself.
Also remove the blue alert reminder section from the "Edit Bookmark" modal as it just added clutter, because the user can already see they had a reminder set:
Adds a default false boolean column `delete_when_reminder_sent` to bookmarks.
We were sharing `Discourse` both as an application object and a
namespace which complicated things for Ember CLI. This patch
moves raw templates into `__DISCOURSE_RAW_TEMPLATES` and adds
a couple helper methods to create/remove them.
This will make a few minor improvements to the second factor user interface. Highlights include:
- Using the site's title to prefix the backup code filename. If non-ascii characters are detected, then prefix "discourse" instead.
- Add icons and change the text on some of the buttons for better clarity and consistency
- Add an education link to the security key modal
* When hovering over the bookmark icon for a post, show the name of the bookmark at the end of the tooltip _if_ it has been set.
* Order bookmarks by `updated_at DESC` in the user list and show that instead of created at.
* Remove Handlebars.SafeString usage
* DEV: Support for `import Handlebars from 'handlebars'`;
* FIX: Sprockets was broken when `node_modules` was present
By default the old version of sprockets looks for application.js
anywhere, including in a node_modules folder if this exists
(which it will when we move to Ember CLI.)
* FEATURE: add category banner for why a user cannot post
Adds a category banner for why a user is unable to post in a category.
Also adds an extra alert for the user when a user is unable to create a topic in a
category and they still try and click on the disabled-looking new topic
button.
Some providers don't implement the Expect: 100-continue support,
which results in a mismatch in the object signature.
With this settings, users can disable the header and use such providers.
We have the `# frozen_string_literal: true` comment on all our
files. This means all string literals are frozen. There is no need
to call #freeze on any literals.
For files with `# frozen_string_literal: true`
```
puts %w{a b}[0].frozen?
=> true
puts "hi".frozen?
=> true
puts "a #{1} b".frozen?
=> true
puts ("a " + "b").frozen?
=> false
puts (-("a " + "b")).frozen?
=> true
```

* Rename all instances of bookmarkWithReminder and bookmark_with_reminder to just bookmark
* Delete old bookmark code at the same time
* Add migration to remove the bookmarkWithReminder post menu item if people have it set in site settings
For clarity and to save space remove the timezone in brackets e.g. (EDT) from the user card. Also add a title to the user time span to say it is Local Time.
This adds a site setting (default off) to optionally show a user's local time and timezone in their user card. For example, I live in Brisbane, and if at 3:30PM my time I were to open a user who lives in California's card I would see 22:30 (PST).
This reverts commit 6f9177e2ed.
We decided on a completely different approach to the problem.
Instead we will let blocked emails be treated as canonical.
If for some reason an update did not go through (for example,
concurrently updating the same topic twice), we were logging something
like:
```
create_errors_json called with unrecognized type: #<Topic
```
This happened because we knew an error occurred but the active record
object had no errors attached.
This patch fixes the issue by attaching a proper error message in the
event that this happens.
The main thrust of this PR is to take all the conditional checks based on the `enable_bookmarks_with_reminders` away and only keep the code from the `true` path, making bookmarks with reminders the core bookmarks feature. There is also a migration to create `Bookmark` records out of `PostAction` bookmarks for a site.
### Summary
* Remove logic based on whether enable_bookmarks_with_reminders is true. This site setting is now obsolete, the old bookmark functionality is being removed. Retain the setting and set the value to `true` in a migration.
* Use the code from the rake task to create a database migration that creates bookmarks from post actions.
* Change the bookmark report to read from the new table.
* Get rid of old endpoints for bookmarks
* Link to the new bookmarks list from the user summary page
