Allow admins to configure exceptions to our Rails rate limiter.
Configuration happens in the environment variables, and work with both
IPs and CIDR blocks.
Example:
```
env:
DISCOURSE_MAX_REQS_PER_IP_EXCEPTIONS: >-
14.15.16.32/27
216.148.1.2
```
Sections with unreserverd characters will appear url-encoded and need to
be unescaped before using it.
Wikipedia generates 2 different spans in this case in the same page, one
with an id resulting of replacing the % symbols with . and the other with
the decoded version of the string. For example, for /wiki/foo#A%C3%A1A it
will generate:
<span id="A.C3.A1A"></span>
<span id="AáA">AáA</span>
Unescaping the `m_url_hash_name` should work in all cases to target the
proper section span.
When a post is flagged with the reason of 'Something Else' a brief message can be added by the user which subsequently creates a `meta_topic` private message. The group `moderators` is automatically added to this topic.
If category group moderation is enabled, and the post belongs to a category with a reviewable group, that group should also be added to the meta_topic.
Note: This extends the `notify_moderators` logic, and will add the reviewable group to the meta_topic, regardless of the settings of that group.
In 2018 check was added that TL1 welcome message is sent unless user already has BasicBadge granted.
I think we should also check if BasicBadge is even enabled. Otherwise, each time group is assigned to a user and trust level is recalculated, they will receive a welcome message.
The following example message would generate an exception:
```
Return-Path: <discourse@bar.com>
From: Foo Bar <discourse@bar.com>
To: reply+4f97315cc828096c9cb34c6f1a0d6fe8@bar.com
Date: Fri, 15 Jan 2016 00:12:43 +0100
Message-ID: <21@foo.bar.mail>
Mime-Version: 1.0
Content-Type: text/html; charset=UTF-8
</div>
```
Exception:
```
NoMethodError:
undefined method `split' for nil:NilClass
```
This reverts a part of changes introduced by https://github.com/discourse/discourse/pull/13947
In that PR I:
1. Disallowed topic feature links for TL-0 users
2. Additionally, disallowed just putting any URL in topic titles for TL-0 users
Actually, we don't need the second part. It introduced unnecessary complexity for no good reason. In fact, it tries to do the job that anti-spam plugins (like Akismet plugin) should be doing.
This PR reverts this second change.
This adds an optional ENV variable, `EMBER_CLI_PROD_ASSETS`. If truthy,
compiling production assets will be done via Ember CLI and will replace
the assets Rails would otherwise use.
This disallows putting URLs in topic titles for TL0 users, which means that:
If a TL-0 user puts a link into the title, a topic featured link won't be generated (as if it was disabled in the site settings)
Server methods for creating and updating topics will be refusing featured links when they are called by TL-0 users
TL-0 users won't be able to put any link into the topic title. For example, the title "Hey, take a look at https://my-site.com" will be rejected.
Also, it improves a bit server behavior when creating or updating feature links on topics in the categories with disabled featured links. Before the server just silently ignored a featured link field that was passed to him, now it will be returning 422 response.
We are still on a version of pretender since 2017
https://github.com/pretenderjs/pretender/releases/tag/v1.6.1
Since then many changes have been made, including adding support
for xhr.upload. Upgrading will let us write proper acceptance
tests for uppy, which uses XmlHTTPRequest internally including
xhr.upload.
Updates pretender to 3.4.7 and fake-xml-http-request to 2.1.2.
Note: There have been no breaking changes in the releases that would
affect us, mainly dropping support for old node versions.
* FIX: Update draft count when sequence is increased
Sometimes users ended up having a draft count higher than the actual
number of drafts.
* FIX: Do not update draft count twice
The call to DraftSequence.next! above already does it.
Discourse automatically sends a private message after backup or
restore finished. The private message used to contain the log inline
even when it was very long. A very long log can create issues because
the length of the post will be over the maximum allowed length of a
post. When that happens, Discourse will try to create an upload with
the logs. If that fails, it will trim the log and inline it.
Inlining secure images with the same name was not possible because they
were indexed by filename. If an email contained two files with the same
name, only the first image was used for both of them. The other file
was still attached to the email.
When the Reply-To header is present for incoming emails we
want to use it instead of the from address. This is usually the
case when forwarding an email via a mailing list into Discourse.
For now we are only using the Reply-To header if the email has
been forwarded via Google Groups, which is why we are checking the
X-Original-From header too. In future we may want to use the Reply-To
header in more cases.
Searching in a category looked only one level down, ignoring the site
setting max_category_nesting. The user interface did not support the
third level of categories and did not display them in the "Categorized"
input of the advanced search options.
* FEATURE: Onebox can match engines based on the content_type
`FinalDestination` now returns the `content_type` of a resolved URL.
`Oneboxer` passes this value to `Onebox` itself. Onebox engines can now specify a `matches_content_type` regex of content_types that the engine can handle, regardless of the URL.
`ImageOnebox` will match URLs with a content type of `image/png`, `jpg`, `gif`, `bmp`, `tif`, etc.
This will allow images that exist at a URL without a file type extension to be correctly rendered, assuming a valid `content_type` is returned.
When a post is created, the draft sequence is increased and then older
drafts are automatically executing a raw SQL query. This skipped the
Draft model callbacks and did not update user's draft count.
I fixed another problem related to a raw SQL query from Draft.cleanup!
method.
We shouldn't be checking if a user is allowed to do an action in the logger. We should be checking it just before we perform the action. In fact, guardians in the logger can make things even worse in case of a security bug. Let's say we forgot to check user's permissions before performing some action, but we still have a call to the guardian in the logger. In this case, a user would perform the action anyway, and this action wouldn't even be logged!
I've checked all cases and I confirm that we're safe to delete this calls from the logger.
I've added two calls to guardians in admin/user_controller. We didn't have security bugs there, because regular users can't access admin/... routes at all. But it's good to have calls to guardian in these methods anyway, neighboring methods have them.
This adds a few different things to allow for direct S3 uploads using uppy. **These changes are still not the default.** There are hidden `enable_experimental_image_uploader` and `enable_direct_s3_uploads` settings that must be turned on for any of this code to be used, and even if they are turned on only the User Card Background for the user profile actually uses uppy-image-uploader.
A new `ExternalUploadStub` model and database table is introduced in this pull request. This is used to keep track of uploads that are uploaded to a temporary location in S3 with the direct to S3 code, and they are eventually deleted a) when the direct upload is completed and b) after a certain time period of not being used.
### Starting a direct S3 upload
When an S3 direct upload is initiated with uppy, we first request a presigned PUT URL from the new `generate-presigned-put` endpoint in `UploadsController`. This generates an S3 key in the `temp` folder inside the correct bucket path, along with any metadata from the clientside (e.g. the SHA1 checksum described below). This will also create an `ExternalUploadStub` and store the details of the temp object key and the file being uploaded.
Once the clientside has this URL, uppy will upload the file direct to S3 using the presigned URL. Once the upload is complete we go to the next stage.
### Completing a direct S3 upload
Once the upload to S3 is done we call the new `complete-external-upload` route with the unique identifier of the `ExternalUploadStub` created earlier. Only the user who made the stub can complete the external upload. One of two paths is followed via the `ExternalUploadManager`.
1. If the object in S3 is too large (currently 100mb defined by `ExternalUploadManager::DOWNLOAD_LIMIT`) we do not download and generate the SHA1 for that file. Instead we create the `Upload` record via `UploadCreator` and simply copy it to its final destination on S3 then delete the initial temp file. Several modifications to `UploadCreator` have been made to accommodate this.
2. If the object in S3 is small enough, we download it. When the temporary S3 file is downloaded, we compare the SHA1 checksum generated by the browser with the actual SHA1 checksum of the file generated by ruby. The browser SHA1 checksum is stored on the object in S3 with metadata, and is generated via the `UppyChecksum` plugin. Keep in mind that some browsers will not generate this due to compatibility or other issues.
We then follow the normal `UploadCreator` path with one exception. To cut down on having to re-upload the file again, if there are no changes (such as resizing etc) to the file in `UploadCreator` we follow the same copy + delete temp path that we do for files that are too large.
3. Finally we return the serialized upload record back to the client
There are several errors that could happen that are handled by `UploadsController` as well.
Also in this PR is some refactoring of `displayErrorForUpload` to handle both uppy and jquery file uploader errors.
In badge queries for 'First Share' and 'Nice/Good/Great Share' badges,
check that the user exists.
For 'Nice+ Share' badges, also grant badges if the number of shares is
equal to the threshhold count to better match the descriptions.
The cache_fullpath for the Stylesheet::Manager was the same for
every test runner in a parallel test environment, so when other
specs or other places e.g. the stylesheets_controller_spec ran
rm -rf Stylesheet::Manager.cache_fullpath this caused errors
for other specs running that went through the
Stylesheet::Manager::Builder#compile path, causing the error
```
Errno::ENOENT:
No such file or directory @ rb_sysopen
```
Also fixed the stylesheet_controller which was interpolating Rails.root + CACHE_PATH
itself instead of just using Stylesheet::Manager.cache_fullpath
Prior to this fix, post whisperer in personal messages are revealed in
the topic's participants list even though non-staff users are unable to
see the whisper.
Using an invalid value was allowed. This commit tries to automatically
fix the color by adding missing # symbol or will show an error to the
user if it is not possible and it is not a CSS color either.
Not specifying an `Accept-Language` should be equivalent to specifying an `Accept-Language` of `*`, however some webservers seem to prefer it if we are explicit about being able to handle a response of content in any language.
