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).
Supervision/management should not be done from inside the container, but
externally, by container managers.
The container now simply runs node on server.js.
The logs are now readable from docker logs <container_name>.
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).
Example of exception we no longer throw:
MALFORMEDJSON

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
