Since this code can end up loaded in browsers when using client side plugins,
avoid use of ES6 syntax features such as arrow functions until MSIE support is
finally dropped.
This change is in preparation of the future async refactoring by Ray. It tries
to extract as many changes in boolean conditions as possible, in order to make
more evident identifying eventual logic bugs in the future work.
This proved already useful in at least one case.
BEWARE: this commit exposes an incoherency in the DB API, in which, depending
on the driver used, some functions can return null or undefined. This condition
will be externally fixed by the final commit in this series ("db/DB.js: prevent
DB layer from returning undefined"). Until that commit, the code base may have
some bugs.
This change extracts the grammar correction performed on the async branch,
anticipating them in a single commit. It cannot be folded with the previous
one, as it is not purely cosmetic.
This change is only cosmetic. Its aim is do make it easier to understand the
async changes that are going to be merged later on. It was extracted from the
original work from Ray Bellis.
To verify that nothing has changed, you can run the following command on each
file touched by this commit:
npm install uglify-es
diff --unified <(uglify-js --beautify bracketize <BEFORE.js>) <(uglify-js --beautify bracketize <AFTER.js>)
This is a complete script that does the same automatically (works from a
mercurial clone):
```bash
#!/usr/bin/env bash
set -eu
REVISION=<THIS_REVISION>
PARENT_REV=$(hg identify --rev "${REVISION}" --template '{p1rev}')
FILE_LIST=$(hg status --no-status --change ${REVISION})
UGLIFYJS="node_modules/uglify-es/bin/uglifyjs"
for FILE_NAME in ${FILE_LIST[@]}; do
echo "Checking ${FILE_NAME}"
diff --unified \
<("${UGLIFYJS}" --beautify bracketize <(hg cat --rev "${PARENT_REV}" "${FILE_NAME}")) \
<("${UGLIFYJS}" --beautify bracketize <(hg cat --rev "${REVISION}" "${FILE_NAME}"))
done
```
The .tex source was updated to fix some typos, but the corresponding pdf was not
regenerated.

Compatibility with IE11 regressed in 23eab79946 while working for #3488.
That commit made use of modern js syntax, not supported by IE11.
- Removed arrow functions, replaced with normal functions.
- Removed the spread operator (<...iterable>) and the "new Set()" construct,
replaced with _.uniq()
At some point IE11 compatibility will be dropped.
Ditching it now, for such a small gain, is not wise.
Fixes#3500.
This is just a dev dependency, so no real risks, but it's better not to scare
users.

Etherpad-lite relies on the user's browser to generate a random pad
name, but the current solution is not safe against collisions. In order
to generate unique pad names, the following modifications are made:
* use a PRNG instead of Math.random() and ensure uniform distribution
when selecting chars.
* choose the pad name length to achieve a specific number of bits of
security.
Closes: #3516
colibris: preparatory changes
This series consists of the preparatory changes done by @seballot on the Etherpad core code in order to prepare it for the introduction of the colibris skin (proposed in #3441).
They were extracted from #3496, isolating the modifications performed outside of skins/colibris.
The expected effects on Etherpad (and its default skin) should be none: any major deviation from the original behavior is to be considered a bug.
A followup series will merge the colibris skin itself.
