The saved revision "star" button appeared in the timeslider toolbar too.
This change introduces a second flag "page" in toolbar.menu(), which controls
whether the toolbar is being drawn for a pad or in the timeslider page.
Fixes#3767.
Revision b480416375 fixed a bug, but introduced a regression, and the "save
revision" "star" button started to appear both on the left and the right
toolbar.
This change introduces a flag "whichMenu" in toolbar.menu(), that controls
whether the left, the right or the timeslider toolbar is being drawn.
By specification [0], the if-modified-since HTTP header sent by browsers does
not include milliseconds.
Before this patch, let's say a file was generate at time:
t_real-file = 2020-03-22T02:15:53.548Z (note the fractional seconds)
When issuing a conditional request, the browser would truncate the fractional
part, and only request an if-modified-since with this contents:
t_if-modified-since = 2020-03-22T02:15:53.000Z
The minify() function would return HTTP/304 only if
t_if-modified-since >= t_real-file, but this would never be true unless, by
chance, a file was generated at XX.000Z.
This resulted in that file being minified/compressed again and resent to the
client for no reason. After this patch, the server correctly responds with
HTTP/304 without doing any computation, and the browser uses the cached file.

CleanCSS 3.4.19 had a Regex Denial of Service vulnerability and has to be
updated. The major version bump requires the following changes:
1. Disabling rebase is necessary because otherwise the URLs for the web fonts
become wrong;
EXAMPLE 1:
/static/css/src/static/font/fontawesome-etherpad.woff
instead of
/static/font/fontawesome-etherpad.woff
EXAMPLE 2 (this is more surprising):
/p/src/static/font/opendyslexic.otf
instead of
/static/font/opendyslexic.otf
2. CleanCSS.minify() can either receive a string containing the CSS, or an array
of strings. In that case each array element is interpreted as an absolute
local path from which the CSS file is read.
In version 4.x, CleanCSS API was simplified, eliminating the relativeTo
parameter, and thus we cannot use our already loaded "content" argument, but
we have to wrap the absolute path to the CSS in an array and ask the library
to read it by itself.
Fixes#3616.
For some reason authorInfo is sometimes null, and therefore it is not possible
to get colorId from it.
This resulted in the following stack trace:
[2020-03-16 09:27:17.291] [ERROR] console - (node:1746) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'colorId' of null

Which is due to a bug in Etherpad that we are not going to solve now.
As a workaround, when this happens, let's set the username to "Anonymous" (if
it is not already set), and colorId to the fixed value "#daf0b2". Warning
messages are written in the logs to signal this condition.
This is no definitive solution, but fixes#3612 (via a workaround).
Before this patch, visiting the read-only URL for a random pad would remove
the "Save Revision" (the "star" icon) from all the other RW pads. The only way
to make it appear again was to restart the server.
This change does not fix the underlying bug: after visiting a read only link
the "star" button would still disapper, but it is explictly reinserted via an
ad-hoc condition.
Fixes#3702
By specification, when settings.allowUnknownFileEnds is true and the user tries
to import a file with an unknown extension (this includes no extension),
Etherpad tries to import it as txt.
This broke in Etherpad 1.8.0, that abruptly terminates the processing with an
UnhandledPromiseRejectionWarning.
This patch restores the intended behaviour, and allows to import as text a file
with an unknown extension (on no extension).
In order to catch the UnhandledPromiseRejectionWarning we had to use
fsp_rename(), which is declared earlier in the code and is promised based
instead of fs.rename(), which is callback based.
Fixes#3710.
Before this change, invoking a non existing API method would return an HTTP/200
response with a JSON payload {"code":3,"message":"no such function"}.
This commit changes the HTTP status code to 404, leaving the payload as-is.
Before:
curl --verbose "http://localhost:9001/api/1/notExisting?apikey=ABCDEF"
< HTTP/1.1 200 OK
< X-Powered-By: Express
[...]
{"code":3,"message":"no such function","data":null}
After:
curl --verbose "http://localhost:9001/api/1/notExisting?apikey=ABCDEF"
< HTTP/1.1 404 OK
< X-Powered-By: Express
[...]
{"code":3,"message":"no such function","data":null}
Fixes#3546.
Steps to reproduce (via HTTP API):
1. create a group via createGroup()
2. create a group pad inside that group via createGroupPad()
3. make that pad public calling setPublicStatus(true)
4. access the pad via a clean web browser (with no sessions)
5. UnhandledPromiseRejectionWarning: apierror: sessionID does not exist
This was due to an overlook in 769933786c: "apierror: sessionID does not
exist" may be a legal condition if we are also visiting a public pad. The
function that could throw that error was sessionManager.getSessionInfo(), and
thus it needed to be inside the try...catch block.
Please note that calling getText() on the pad always return the pad contents,
*even for non-public pads*, because the API bypasses the security checks and
directly talks to the DB layer.
Fixes#3600.
The mechanism used for determining if the application is being served over SSL
is wrapped by the "express-session" library for "express_sid", and manual for
the "language" cookie, but it's very similar in both cases.
The "secure" flag is set if one of these is true:
1. we are directly serving Etherpad over SSL using the native nodejs
functionality, via the "ssl" options in settings.json
2. Etherpad is being served in plaintext by nodejs, but we are using a reverse
proxy for terminating the SSL for us;
In this case, the user has to be instructed to properly set trustProxy: true
in settings.json, and the information wheter the application is over SSL or
not will be extracted from the X-Forwarded-Proto HTTP header.
Please note that this will not be compatible with applications being served over
http and https at the same time.
The change on webaccess.js amends 009b61b338, which did not work when the SSL
termination was performed by a reverse proxy.
Reference for automatic "express_sid" configuration:
https://github.com/expressjs/session/blob/v1.17.0/README.md#cookiesecureCloses#3561.
The "io" cookie is created by socket.io, and its purpose is to offer an handle
to perform load balancing with session stickiness when the library falls back to
long polling or below.
In Etherpad's case, if an operator needs to load balance, he can use the
"express_sid" cookie, and thus "io" is of no use.
Moreover, socket.io API does not offer a way of setting the "secure" flag on it,
and thus is a liability.
Let's simply nuke it.
References:

The change that implemented #3648 (7c099fef5e) was incorrect, and resulted
in disabling every user at startup.
The problem was twofold:
1. _.filter() on an object returns an array of the object's enumerable values
and strips out the keys, see: https://stackoverflow.com/questions/11697702/how-to-use-underscore-js-filter-with-an-object
To filter an object, the function that needs to be used is _.pick();
2. The logic condition on userProperties.password was plain wrong (it should
have been an AND instead of an OR).
This change corrects 1) and 2), and writes more specific logs when something
goes wrong.
Closes#3661.
Nodejs 8 will be EOLed on December 31th, 2019 (https://github.com/nodejs/Release).
This means any future Etherpad version released from 2020 on should require at
least the next LTS (10.13.0). Let's keep some margin and decide that the first
Etherpad version dropping node 8 compatibility will be 1.8.3.
Closes#3650.
Do not touch vendorized files (e.g. libraries that were imported from external
projects).
No functional changes.
Command:
find . -name '*.<EXTENSION>' -type f -print0 | xargs -0 sed -i 's/[[:space:]]*$//'
Currently the version is exposed in a 'Server' http headers.
This commit allows to parameterize it in the settings. By defaults it is
not exposed.
Fixes#3423
In this way the only external call to statFile() provides an explicit value for
"dirStatLimit", and thus the initial check on "undefined" at the start of the
function could be removed (just added a comment for now).
All the configuration values can be read from environment variables using the
syntax "${ENV_VAR_NAME}".
This is useful, for example, when running in a Docker container.
EXAMPLE:
"port": "${PORT}"
"minify": "${MINIFY}"
"skinName": "${SKIN_NAME}"
Would read the configuration values for those items from the environment
variables PORT, MINIFY and SKIN_NAME.
REMARKS:
Please note that a variable substitution always needs to be quoted.
"port": 9001, <-- Literal values. When not using substitution,
"minify": false only strings must be quoted: booleans and
"skin": "colibris" numbers must not.
"port": ${PORT} <-- ERROR: this is not valid json
"minify": ${MINIFY}
"skin": ${SKIN_NAME}
"port": "${PORT}" <-- CORRECT: if you want to use a variable
"minify": "${MINIFY}" substitution, put quotes around its name,
"skin": "${SKIN_NAME}" even if the required value is a number or a
boolean.
Etherpad will take care of rewriting it to
the proper type if necessary.
Resolves#3543
Before this commit, when passed a malformed credentials.json the application
crashed with a stack dump. Now we catch the error and fail in a controlled way
(like already done for settings.json).

ueberDB2 can return either undefined or null for a missing key, depending on
which DB driver is used. This patch changes the promise version of the API so
that it will always return null.
some code chunks previously used `async.parallel` but if you
use `await` that forces them to be run serially. Instead,
you can initiate the operation (getting a Promise) and then
_later_ `await` the result of that Promise.
If you use `await` inside a loop it makes the loop inherently serial.
If you omit the `await` however, the tasks will all start but the loop
will finish while the tasks are still being scheduled.
So, to make a set of tasks run in parallel but then have the
code block after the loop once all the tasks have been completed
you have to get an array of Promises (one for each iteration) and
then use `Promise.all()` to wait for those promises to be resolved.
Using `Array#map` is a convenient way to go from an array of inputs
to the require array of Promises.
NB1: needs additional review and testing - no abiword available on my test bed
NB2: in ImportHandler.js, directly delete the file, and handle the eventual
error later: checking before for existence is prone to race conditions,
and does not handle any errors anyway.
- removed possible issue with failing to sanitize `padName` if `padId` was also
supplied
- removed unnecessary `try` block
- simplified API and function name matching tests
Also converted the handler functions that depend on checkAccess() into async
functions too.
NB: this commit needs specific attention to it because it touches a lot of
security related code!
This patch also contains significant refactoring relating to error checking of
arguments supplied to the functions (e.g. rev) facilitated by use of `throw`
instead of nodeback errors.
1. This module was not migrated to Promises, because it is only used via
express-session, which can't actually use promises anyway.
2. all(), clear() and length() depend on the presence of the `db.forEach()`
function, which in ueberdb2 doesn't even exist.
Fortunately those three methods are optional, so I made their existence
conditional on the presence of `db.forEach`.
3. in SessionStore.clear(), replaced a call to db.db.remove() with db.remove()
Changed two occurrences of:
process.nextTick(function() {
if (fn) fn();
});
with
if (fn) {
process.nextTick(fn);
}
i.e. such that no function even gets added to the `nextTick` queue unless
there's actually a function to be called.
Extracted from Ray's work.
`getPadAccess()` (src/node/padaccess.js) is now "promise only", resolving to
`true` or `false` as appropriate, and throwing an exception if there's an
error.
The two call sites (padreadonly.js and importexport.js) updated to match.
