* Run node 10 with '--experimental_worker' flags
* Use dedicated function to retrieve node/npm program version
The goal of this commit is to ensure that any linux based node 10 deployments run with the experimental_worker flag. This flag is required for workers to "work" in node 10. This will not affect other versions of node. This resolves#4335 where Docker would fail due to being based on node 10.
This makes it easier to see the test results, and it hides some
scary-looking but intentional error messages.
This code will likely have to be updated if/when we change the logging
library (see issue #1922).
This currently isn't absolutely necessary because all current callers
of `userCanModify` already check for a read-only pad ID themselves.
However:
* This adds defense in depth.
* This makes it possible to simply replace the import handler's
`allowAnyoneToImport` check with a call to `userCanModify`.
This makes it possible to test various settings combinations and
examine internal state to confirm correct behavior. Also, the user
doesn't need to start an Etherpad server before running these tests.
There's no need to perform an authentication check in the socket.io
middleware because `PadMessageHandler.handleMessage` calls
`SecurityMananger.checkAccess` and that now performs authentication
and authorization checks.
This change also improves the user experience: Before, access denials
caused socket.io error events in the client, which `pad.js` mostly
ignores (the user doesn't see anything). Now a deny message is sent
back to the client, which causes `pad.js` to display an obvious
permission denied message.
This also fixes a minor bug: `settings.loadTest` is supposed to bypass
authentication and authorization checks, but they weren't bypassed
because `SecurityManager.checkAccess` did not check
`settings.loadTest`.
Rather than reinvent the wheel, use a well-tested library to parse and
write cookies. This should also help prevent XSS vulnerabilities
because the library handles special characters such as semicolon.
* Use the cookie functions from `pad_utils.js`.
* Delete unused methods, variables, and parameters.
* Simplify the logic.
* Use an ES6 class instead of a weird literal thingy.
* Use `const` instead of `var`.
Previously Etherpad would not pass the correct client IP address through and this caused the rate limiter to limit users behind reverse proxies. This change allows Etherpad to use a client IP passed from a reverse proxy.
Note to devs: This header can be spoofed and spoofing the header could be used in an attack. To mitigate additional *steps should be taken by Etherpad site admins IE doing rate limiting at proxy.* This only really applies to large scale deployments but it's worth noting.
Not every string was localized:
* `/admin/plugins` has some CSS magic to draw the tables of plugins
differently on narrow (mobile) screens, and the l10n library we
use does not support that particular magic. The strings that were
not localized are "Name", "Description", "Version", and "Time".
These strings are only stuck in English when the page is viewed on
a narrow screen; normal desktop users will see translated strings.
The CSS magic ought to be replaced with something more robust
(lots of nested `div`s); those remaining strings can be localized
whenever that happens.
* Strings from external sources such as plugin descriptions, error
messages, and `settings.json` comments are not localized.
Before this change, the authorize hook was invoked twice: once before
authentication and again after (if settings.requireAuthorization is
true). Now pre-authentication authorization is instead handled by a
new preAuthorize hook, and the authorize hook is only invoked after
the user has authenticated.
Rationale: Without this change it is too easy to write an
authorization plugin that is too permissive. Specifically:
* If the plugin does not check the path for /admin then a non-admin
user might be able to access /admin pages.
* If the plugin assumes that the user has already been authenticated
by the time the authorize function is called then unauthenticated
users might be able to gain access to restricted resources.
This change also avoids calling the plugin's authorize function twice
per access, which makes it easier for plugin authors to write an
authorization plugin that is easy to understand.
This change may break existing authorization plugins: After this
change, the authorize hook will no longer be able to authorize
non-admin access to /admin pages. This is intentional. Access to admin
pages should instead be controlled via the `is_admin` user setting,
which can be set in the config file or by an authentication plugin.
Also:
* Add tests for the authenticate and authorize hooks.
* Disable the authentication failure delay when testing.
This loses some of the granularity of the default HTTP basic auth
(unknown username vs. bad password), but there is considerable value
in having logging that is consistent no matter what authentication
plugins are installed.
The export request hook wasn't testing if the pad's id was from a read-only
pad before validating with the pad manager.
This includes an extra step that makes the read-only id verification and also
avoids setting the original pad's id as the file's name.
This PR introduces testing of plugins from the ether/ organization on Github. Each plugin is added into ``.travis``. Frontend plugins tests are run exclusive to core tests. Backend runs both core and plugins with core.
Including frontend core tests with plugin tests caused the session to overrun causing errors.
