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).
Example of exception we no longer throw:
MALFORMEDJSON

SyntaxError: Unexpected token M in JSON at position 0

This is a super simple start.
At minimum, configuration via environment variables (see #3543) needs to be
integrated in Etherpad to make this user-friendly.
Resolves#3524.
With this commit, that closes#3540, we pay the first big slice of our technical
debt. In this line of work we streamlined the code base, reducing its size by
15-20% and making it more understandable at the same time.
The changes were audited and tested collaboratively and are deemed sufficiently
stable for being merged.
Known issues:
- plugin compatibility is still not perfect
- the error handling path needs to be improved
This is an important day for Etherpad: thanks, Ray!
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.
This is documented to be more performant.
The substitution was made on frontend code, too (i.e., the one in /static),
because Date.now() is supported since IE 9, and we are life supporting only
IE 11.
Commands:
find . -name *.js | xargs sed --in-place "s/new Date().getTime()/Date.now()/g"
find . -name *.js | xargs sed --in-place "s/(new Date()).getTime()/Date.now()/g"
Not done on jQuery.
The guard condition on count being non negative and < 100 used the wrong
boolean operator. In its form it was impossible.
This error was introduced in 2013, in 5592c4b0fe.
Fixes#3499
The HTTP API doesn't ever omit arguments, it always passes `undefined` for a
parameter that wasn't supplied in the request.
The functions that were simplified are:
- getRevisionChangeset()
- getText()
- getHTML()
- saveRevision()
The only function still supporting optional arguments is getPadSafe(), which is
only called from this module.
This function was simulating two overloads:
1. copy(destinationID, force, callback)
2. copy(destinationID, callback), in this case "force" would be assumed false
But all the call sites always used the version with arity 3.
Thus, we can remove that optionality and always assume that the funcion will be
called with three parameters. This will simplify future work.
Moving classes to html tag so it can be used to style other part of template depending on plugins like #users, #chat etc...
Rename plugin class with "plugin-" prefix, because there were conflicts with some plugins using the same .ep_font_color class to apply css rules
- path.exists() is no longer part of nodejs
- fs.exists() is deprecated (as of nodejs >= 8)
- checking a file for existence before using it is open to raca condition. It is
preferable to go ahead and use the file, and eventually handle the error
- we can afford two simple synchronous fs operations here
Next version will be Etherpad 1.8. As planned in #3424, we are going to require
NodeJS >=8.9.0 and npm >= 6.4.
This commit implements that change and updates documentation and scripts.
Subsequent changes will get rid of old idioms, dating back to node < 0.7, that
still survive in the code.
Once migrated to NodeJS 8, we will be able to start working on migrating the
code base from callbacks to async/await, greatly simplifying legibility (see
#3540).
Closes#3557
Until Etherpad 1.7.5, process.on('SIGTERM') and process.on('SIGINT') were not
hooked up under Windows, because old nodejs versions did not support them.
This excluded the possibility of doing a graceful shutdown of the database
connection under that platform.
According to nodejs 6.x documentation, it is now safe to do so. This allows to
gracefully close the DB connection when hitting CTRL+C under Windows, for
example.
Source: https://nodejs.org/docs/latest-v6.x/api/process.html#process_signal_events
- SIGTERM is not supported on Windows, it can be listened on.
- SIGINT from the terminal is supported on all platforms, and can usually be
generated with <Ctrl>+C (though this may be configurable). It is not
generated when terminal raw mode is enabled.
A Windows manual install has the same directory layout of a normal Unix one
(e.g. the nice symlink node_modules/ep_etherpad-lite -> ../src).
Only when running from the pre-built Windows package the directory layout is
different (e.g. src is physically copied into node_modules/ep_etherpad-lite).
The previous version of the code wrongly assumed that all Windows installs would
be run from the pre-built pakage.
In this version the path search is the same on all platform. If it fails, and we
are on Windows, there is a fallback for the specific case of the pre-built
package.
Fixes#3550
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.
