Also add symlinks from the old `bin/` and `tests/` locations to avoid
breaking scripts and other tools.
Motivations:
* Scripts and tests no longer have to do dubious things like:
require('ep_etherpad-lite/node_modules/foo')
to access packages installed as dependencies in
`src/package.json`.
* Plugins can access the backend test helper library in a non-hacky
way:
require('ep_etherpad-lite/tests/backend/common')
* We can delete the top-level `package.json` without breaking our
ability to lint the files in `bin/` and `tests/`.
Deleting the top-level `package.json` has downsides: It will cause
`npm` to print warnings whenever plugins are installed, npm will
no longer be able to enforce a plugin's peer dependency on
ep_etherpad-lite, and npm will keep deleting the
`node_modules/ep_etherpad-lite` symlink that points to `../src`.
But there are significant upsides to deleting the top-level
`package.json`: It will drastically speed up plugin installation
because `npm` doesn't have to recursively walk the dependencies in
`src/package.json`. Also, deleting the top-level `package.json`
avoids npm's horrible dependency hoisting behavior (where it moves
stuff from `src/node_modules/` to the top-level `node_modules/`
directory). Dependency hoisting causes numerous mysterious
problems such as silent failures in `npm outdated` and `npm
update`. Dependency hoisting also breaks plugins that do:
require('ep_etherpad-lite/node_modules/foo')
Normally I would let `eslint --fix` do this for me, but there's a bug
that causes:
const x = function ()
{
// ...
};
to become:
const x = ()
=> {
// ...
};
which ESLint thinks is a syntax error. (It probably is; I don't know
enough about the automatic semicolon insertion rules to be confident.)
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.
Three of the four tests fail if `settings.allowAnyoneToImport` is
false. The fourth ("tries to import Plain Text to a pad that does not
exist") isn't particularly useful when `settings.allowAnyoneToImport`
is false: That test tests an import failure mode, and when
`settings.allowAnyoneToImport` is false the failure could be caused by
that instead of the expected cause.
Just final bits of test coverage for import/export of LibreOffice. It turns out Travis by default installs an old LO that doesn't support PDF import. To remedy that I use the LO PPA and also strict install the PDF import support.
Still to do in a future date is check LO exported contents includes expected strings, for now it just checks output length looks sane.
