After querying the noteBucket we run notesLoaded with an empty notes array. This causes havoc because we rely on notes being null until notes are loaded. This commit adds a check to ensure there is at least one note before running notesLoaded

Before this change "Loading Notes" is shown for a split second before "No Notes" is shown until notes are loaded.

Fix

Fixes: #1678

Test

  1. Have lots of notes
  2. Clear application state
  3. Observe that Loading Notes is displayed until notes are loaded

Review

Only one developer is required to review these changes, but anyone can perform the review.

Release

RELEASE-NOTES.txt was updated in e848f1b with:

  • Stop showing that there are no notes when initially loading notes from the server.

This was a confusing one! I think the code is right for the wrong reasons 🙃

loadNotes might be misleading but given the way the system works I verified that there is really no other place to put this guard. When we initially receive the index call we don't have any notes in storage. they are probably coming asynchronously after this call but they aren't there regardless, so if there are notes we'll instantly get update signals and re-render

I tested with an account with no notes and an account with many notes. In develop I saw the behavior where it shows "No Notes" when it shouldn't and in this branch it worked as expected.

Thanks for tackling this!

* Refactor tag operations to stop directly mutating tag objects (#1638)

See #1614

As part of a broader effort to resolve data-flow issues in the app this PR is a
first step in removing direct mutation where transactional atomic updates
should be occurring.

It's not clear if the existing code is the source of existing defects in the software
and this is part of why the code is problematic; we have created inherent
concurrency flaws that open up extremely-difficult-to-reproduce bugs.

Resolving this may or may not resolve any existing bugs but it will definitely
help guard us from introducing new ones.

---

Previously we have been directly mutating note and tag objects when
editing those tags. This mutation can lead to concurrency defects which
expose themselves as inconsistent UI state. This breaks our Redux model
which assumes that all UI updates happen atomically.

In this patch we're building new note objects and tag objects when we
make these updates in order to maintain our consistency.

---

There should be no significant visual or behavioral changes with this PR. We
are changing code related to removing tags, renaming tags, and
reordering tags.

In testing verify that with separate sessions the updates appear as expected.
Add, reorder, and remove tags to make sure the changes synchronize.

Previously we have been directly mutating the note object when updating
its content. This may have been an attempt to work around confusing
data-flow issues that thankfully don't exist anymore. We have also been
performing inline checks to make sure that we update the editor's
contents if we receive these updates.

This mutation can lead to concurrency defects which expose themselves as
inconsistent UI state. This breaks our Redux model which assumes that
all UI updates happen atomically.

In this patch we're building a new note object when we update a note
in order to maintain our consistency. In light of #1598 we're also
removing some work-around code that attempted to force consistency when
it didn't exist; that consistency now exists since we're tracking the
underlying Simperium data closely now vs. storing it in separate
places.

When updating checklist items we're forcing a sync so that those changes
will propagate immediately. We don't have a need to debounce those
clicks.

* Fix: Broken oAuth flow (#1627)

We have been experiencing problems when trying to login with the
WordPress.com signin. Something appears to have changed in Electron such
that the older versions of the app still work but newer versions are
failing.

In this patch we're rewriting the authentication flow to simplify it and
prepare ourselves for better handling of the failure cases.

In production we are seeing strange behaviors on failure and some on
success: unending re-requests to `simplenote://auth` which trigger full
CPU load; and no response after authentication.

After this patch we should be able to wrangle in errors and add a
timeout to better communicate when things are failing.

Additionally, the unending loop should be closed due to a replacement of
the old network intercept code with a single simplified model.

We have also been sharing sessions between the main window and the auth
window and also sharing sessions between teach time the auth window
appears.

This leads to leaked cookies and can result in confusing flows, largely
because of the shared cookies.

In this patch we're creating a new `Session` for the auth window every
time we open it. By not including `persist:` in the "partition" name
we're making sure it only exists in memory. By introducing randomness
into its name we're making sure we don't share the same session from
one auth attempt to the next. By freeing the window after close we're
making sure we don't leak memory.

Previously we were able to open the auth window after closing it and
instead of logging in again it would open to the "Accept/Deny" view.
After this change it requires logging in on every attempt. This will
likely be more frustrating but much safer than the previous behavior.

* Make system setting the default theme preference (#1581)

* Make system setting the default theme preference

* Update Release Notes

* Make system the first item in the list

* Update system theme logic

* Add option to hide menu bar (#1215)

Closes #293
Based on #1216

This adds an option to auto-hide the menu bar on Windows/Linux Electron. The option will be in Settings ▸ Display.

screen shot 2019-02-21 at 23 26 17

We have to be careful not to get the user stuck in a situation where they can't bring back the menu bar, so we'll show the Settings button and footer links in the Navigation Bar when auto-hide is enabled.

* Support the unicode bullet as a list item bullet in unordered lists (#1551)

Support the unicode bullet character • as a list item bullet because lists copied from HTML or word documents may contain this character.

* Add release note adding bullet char to lists (#1646)

* Note list: Distinguish loading from empty states (#1650)

Alternative idea to #1649

There are a few times when we boot the app and our list of notes is
empty because we haven't received udpates from the server yet. This
happens on intial app boot, immediately after authorizing, and when
we lose our local copy of the notes from `IndexedDB`.

During these times we're showing that there are no notes in the account
which is misleading. In this patch we're starting with a `null` value
for the notes so that we can distinguish between "there are no notes
in the account" and "we haven yet to determine which notes are in the
account."

In comparison to #1649 we're using a tri-state value for `notes` instead
of introducing an additional flag which must be kept in sync with
`notes`.

* Deps: Update simperium to fix infinite duplication bug

Update `simperium` library to incorporate changes that fixed a defect
where we were holding open old WebSocket connections after signing-out
and signing-in. This defect produced an infinite duplication of changes.

* Update the link to the Release Notes in the updater config (#1675)

Update the link to the Release Notes in the updater config

In (#1582) CHANGELOG.md was renamed to RELEASE-NOTES.txt. This caused the link to the release notes to break.

* In Dev mode, open CHrome Deve Tools in detached mode (#1660)

* Update version in package.json for 1.10.0 release

Added the beta version for 1.10.0-beta1 release

* Fix/only run notes loaded when notes loaded (#1680)

* Only run notesLoaded when notes are indeed loaded

After querying the noteBucket we run notes loaded with an empty notes array. This causes havoc because we rely on notes being null until notes are loaded. This commit adds a check to ensure there is at least one note before running notesLoaded
