Indexing query strings in URLS produces inconsistent results in PG and
pollutes the search data for really little gain.
The following seems to work as expected...
```
discourse_development=# SELECT TO_TSVECTOR('https://www.discourse.org?test=2&test2=3');
to_tsvector
------------------------------------------------------
'2':3 '3':5 'test':2 'test2':4 'www.discourse.org':1
```
However, once a path is present
```
discourse_development=# SELECT TO_TSVECTOR('https://www.discourse.org/latest?test=2&test2=3');
to_tsvector
----------------------------------------------------------------------------------------------
'/latest?test=2&test2=3':3 'www.discourse.org':2 'www.discourse.org/latest?test=2&test2=3':1
```
The lexeme contains both the path and the query string.
```
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
```
Previously, we would only take either the `MIN` or `MAX` for
`post_number` during aggregation meaning that the ranking is not
considered.

On large topics, the cost of sending the entire post ID list back over to the database is signficant. Just have the DB recalculate the list of visible posts instead.
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.
When creating a bookmark reminder that deletes the bookmark on reminder, if the user clicked on the notification and got taken to the post in the topic the bookmark icon still showed as blue with the reminder clock indicator. This was because the response JSON for reloading a topic post was not including the bookmark attributes, not even the bookmarked boolean.
We now return the correct attributes in the serializer, and if bookmarked is false we clear all the bookmark related attributes on the post for the notification to make sure nothing of the old bookmark remains in the UI.
This was only a problem if the user did not refresh the app completely inbetween setting the reminder and receiving the notification.
It's a little awkward to test constants by re-assigning them so
I've added a new parameter to `Discourse.find_compatible_resource`
which can be used by tests.
Instead of loading all of the user bookmarks using all the post IDs in a topic, load all the bookmarks for a user using the topic ID. This eliminates a costly WHERE ID IN query.
We have a couple of examples of enormous amounts of text being entered in the name column of bookmarks. This is not desirable...it is just meant to be a short note / reminder of why you bookmarked this.
This PR caps the column at 100 characters and truncates existing names in the database to 100 characters.
* FIX: Improve category hashtag lookup
This commit improves support for sub-sub-categories and does not include
the ID of the category in the slug, which fixes the composer preview.
* FIX: Sub-sub-categories can be mentioned using only two levels
* FIX: Remove support for three-level hashtags
* DEV: Simplify code
Adds a new rake task `plugin:checkout_compatible_all` and
`plugin:checkout_compatible[plugin-name]` that check out compatible plugin
versions.
Supports a .discourse-compatibility file in the root of plugins and themes that
list out a plugin's compatibility with certain discourse versions:
eg: .discourse-compatibility
```
2.5.0.beta6: some-git-hash
2.4.4.beta4: some-git-tag
2.2.0: git-reference
```
This ensures older Discourse installs are able to find and install older
versions of plugins without intervention, through the manifest only.
It iterates through the versions in descending order. If the current Discourse
version matches an item in the manifest, it checks out the listed plugin target.
If the Discourse version is greater than an item in the manifest, it checks out
the next highest version listed in the manifest.
If no versions match, it makes no change.
If any value, including nil, is passed in as an argument the default
won't be set, so we need to handle when a non-Array value is passed in
to the `generate_thumbnails!` method.
This is a very expensive process, and it should only be required in exceptional circumstances. It is possible to run a similar recovery using `rake uploads:recover` (5284d41a8e/lib/upload_recovery.rb (L135-L184))
`OptimizedImage#filesize` calls `Discourse.store.download` with an OptimizedImage as an argument. It would in turn attempt to call `#original_filename` and `#secure?` on that object. Both would fail as these methods do not exist on OptimizedImage, only on Upload. We didn't know about these issues because:
1. `#calculate_filesize` is not called often, because the filesize is saved on OptimizedImage creation, so it's used mostly for manual filesize recalculation
2. we were using `rescue nil` which swallows all errors
Previously, while generating the topic page's canoncial url we used the current post number. It will create invalid canonical path if the topic has whsiper posts. Now we only taking the visible posts for current page index calculation.
The previous fix (f43c0a5d85) wasn't working for images that were already uploaded.
The "metadata" (eg. 'for_*' and 'secure' attributes) were not added to existing uploads.
Also used 'Upload.get_from_url' is the admin/site_setting controller to properly retrieve
an upload from its URL.
Fixed the Upload::URL_REGEX to use the \h (hexadecimal) for the SHA
Follow-up-to: f43c0a5d85
When uploading an image as a site setting, we need to return the "raw" URL, otherwise
when saving the site setting, the upload won't be looked up properly.
Follow-up-to: f11363d446
* FIX: Correct version comparison logic when comparing stable to beta
For example, version 1.3.0 should be considered higher than 1.3.0.beta3. So `Discourse.has_needed_version?('1.3.0', '1.3.0.beta3')` should return true
* Switch to use Gem::Version to compare versions
When rebaking a post we were invalidating _regular_ oneboxes but not inline oneboxes.
DEV: also renamed 'InlineOneboxer.purge' to 'InlineOneboxer.invalidate' to keep
the API consistent with 'Oneboxer.invalidate'
#b19dcac2 improved the serializer so it sends default notification
levels to users to work around cases where a category edit would
would result in clients being left with invalid notification state
Unfortunately this did not address the root issue.
When we edit categories we publish state to multiple users this
means that the serializer is executed unscoped with no user.
The client already handles this case per:
dcad720a4c/app/assets/javascripts/discourse/app/models/site.js (L119-L119)
If a property is not shipped to it, it will leave it alone on the
existing category.
This fix ensures that these wide category info updates do not
include notification state to avoid corruption of local state.
When linking to a topic in the same Discourse, we try to onebox the link to show the title
and other various information depending on whether it's a "standard" or "inline" onebox.
However, we were not properly detecting links to topics that had no slugs (eg. https://meta.discourse.org/t/1234).
This is causing issues when purging old users, if they are set up in the
exact condition where they will be demoted into another group, but also
do not have a primary email.
* 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
