Quite a few other fixes, including:
- Sending to contact with no avatar yet (not synced from mobile)
- Left pane doesn't update quickly or at all on new message
- Left pane doesn't show sent or error status
Also:
- Contributing.md: Ensure set of linux dev dependencies is complete
* Remove extra parenthesis causing warnings on latest chromium
* Update to electron 2.0.1
* Move all @types dependencies to devDependencies
* Update electron-builder/electron-updater
* Update to Node.js 8.9.3 to match Electron 2.0.1
This does not work with `ArrayBuffer` out of the box and will need to be
investigated and tested more before switching.
Some APIs also seemed to have changed:
- Before (OOP): `new textsecure.protobuf.WebSocketMessage(…).encode();`
- After (functional):
```
textsecure.protobuf.WebSocketMessage.encode(
new textsecure.protobuf.WebSocketMessage(…)
);
```
This reverts commit d758119d9de4f99742ea941e86180b1d600c2f22.
We missed a couple directories with previous attempts to turn this on
globally: app/ and libtextsecure/
Not to mention files in places we didn't expect: ts files that weren't
in the ts directory!
This turns prettier on for every file we care about (js, ts, tsx, md)
everywhere in the project but for a few key parts.
- messages.getQuoteObjectUrl: early return
- backup.js: explaining variables for long if statement
- types/messages.js: Log if thumbnail has neither data nor path
- sendmessage.js:
- remove extraneous logging
- fix indentation
- upload attachments and thumbnails in parallel
- preload: don't load fs for tests, just fse
- _conversation.scss: split two selectors into two lines, 0px -> 0
- backup_test.js: use fse.existsSync and comment twoSlashes regex
- network_tests_view_test.js: Comment duplicate assignment to window.getSocketStatus
1. MessageReceiver always pulls down thumbnails included in quotes
2. Message.upgradeSchema has a new schema that puts all thumbnails on
disk just like happens with full attachments.
3. handleDataMessage pipes quote from dataMessage into the final message
destined for the database
As described in #998, images are sometimes displayed with an incorrect
orientation. This is because cameras often write files in the native sensor byte
order and attach the `Orientation` EXIF metadata to tell end-user devices how to
display the images based on the original author’s capture orientation.
Electron/Chromium (and therefore Signal Desktop) currently doesn’t support
applying this metadata for `<img>` tags, e.g. CSS `image-orientation: from-
image`. As a workaround, this change uses the `loadImage` library with the
`orientation: true` flag to auto-orient images ~~before display~~ upon receipt
and before sending.
**Changes**
- [x] ~~Auto-orient images during display in message list view~~
- [x] Ensure image is not displayed until loaded (to prevent layout reflow) .
- [x] Auto-orient images upon receipt and before storing in IndexedDB
(~~or preserve original data until Chromium offers native fix?~~)
- [x] Auto-orient images in compose area preview.
- [x] ~~Auto-orient images in lightbox view~~
- [x] Auto-orient images before sending / storage.
- [x] Add EditorConfig for sharing code styles across editors.
- [x] Fix ESLint ignore file.
- [x] Change `function-paren-newline` ESLint rule from
`consistent` to `multiline`.
- [x] Add `operator-linebreak` ESLint rule for consistency.
- [x] Added `blob-util` dependency for converting between array buffers,
blobs, etc.
- [x] Extracted `createMessageHandler` to consolidate logic for
`onMessageReceived` and `onSentMessage`.
- [x] Introduce `async` / `await` to simplify async coding (restore control flow
for branching, loops, and exceptions).
- [x] Introduce `window.Signal` namespace for exposing ES2015+ CommonJS modules.
- [x] Introduce rudimentary `Message` and `Attachment` types to begin defining a
schema and versioning. This will allow us to track which changes, e.g.
auto-orient JPEGs, per message / attachment as well as which fields
are stored.
- [x] Renamed `window.dataURLtoBlob` to `window.dataURLToBlobSync` to both fix
the strange `camelCase` as well as to highlight that this operation is
synchronous and therefore blocks the user thread.
- [x] Normalize all JPEG MIME types to `image/jpeg`, eliminating the
invalid `image/jpg`.
- [x] Add `npm run test-modules` command for testing non-browser specific
CommonJS modules.
- **Stretch Goals**
- [ ] ~~Restrict `autoOrientImage` to `Blob` to narrow API interface.~~ Do
this once we use PureScript.
- [ ] ~~Return non-JPEGs as no-op from `autoOrientImage`.~~ Skipping
`autoOrientImage` for non-JPEGs altogether.
- [ ] Retroactively auto-orient existing JPEG image attachments in the
background.

Implement attachment process version
Instead of keeping track of last normalization (processing) date, we now
keep track of an internal processing version that will help us understand
what kind of processing has already been completed for a given attachment.
This will let us retroactively upgrade existing attachments.
As we add more processing steps, we can build a processing pipeline that can
convert any attachment processing version into a higher one,
e.g. 4 -> 5 -> 6 -> 7.

Test CommonJS modules separately
Not sure how to test them as part of Grunt `unit-tests` task as
`test/index.html` doesn’t allow for inclusion of CommonJS modules that use
`require`. The tests are silently skipped.

This module exposes `loadImage` with a `Promise` based interface and pre-
populates `orientation: true` option to auto-orient input. Returns data URL
as string.
The module uses a named export as refactoring references of modules with
`default` (`module.exports`) export references can be error-prone.

Sync service protocol buffers with Java project
Snapshot: 4684a49b2e/protobuf/SignalService.proto
* Log SyncMessage destination, even if it's a group
* Remove disappearing message even if deleted during fetch
This change fixes a potential race condition with disappearing message
removal from the UI. If the UI is in the middle of making a database
request for messages to display, then we need to wait for that to
complete before removing the newly-deleted expired message.
* api.js: HttpError now preserves more of original error info
* Allow invalid conversation to be added to ConversationController
If a number we don't believe is valid comes in as part of a group, we
fall apart. We event prevent display of that conversation. Because we
have 'isValid()' protections in place for the places we create contacts
from user input in desktop (the search bar), we can temporarily add an
invalid contact to our collection (not saving it to the database) to
unblock this group scenario.
Still investigating what kind of phone number is valid in a mobile app
but not valid for us.
* Finish the debuggable error support
* Fix logging in the case of an invalid number
* Revamp issue and pull request templates, other docs tweaks
`yarn test` now runs all of our tests.
* Remove generated files from the repository
* Update to new Signal support URL
* Prevent the 'Test failed 2 == 1' from test-release in CI
* Another attempt to fix grunt test-release on Appveyor
* grunt test-release: Fail build if test fails
* Lint fix, and move jshint earlier in CI process
No more errors like this in the logs!
```

It has no information in the title, and then the callstack points to
the `new Error()` line in the old `errors.js`.
This change will include the actual error name and message details in
the stack, and will include the original http error stack as well if
provided.
We've simplified; HTTPS_PROXY or https_proxy is used for all requests.
We also require that only our self-signed certificates are used for
secure traffic. That rules out all SSL-terminating MITM proxies, since
we don't trust their root certificate.
Once we're sure that this system works for people, we'll improve config
on MacOS and Windows.
We pull proxy settings from environment variables:
- HTTPS_PROXY for sending, profile pulls, and attachment download/upload
- WSS_PROXY for connecting to the websocket for receiving messages
- ALL_PROXY to provide one server for both
More details on our proxy handling:
- https://github.com/Rob--W/proxy-from-env#environment-variables
- https://github.com/TooTallNate/node-proxy-agent
This is the natural way of things for Linux. My understanding is that
most proxies on MacOS are system-wide and transparent, so it's not so
urgent. But Windows will likely require further UI for configuration.
Will need to do some testing with Windows users.
* Re-enable libtextsecure unit tests, get passing, run in CI
* Save prekeys optimistically, track confirmed, new clean behavior
* Eliminate potential conflicts when rotating on startup
* Remove last symlink: get libtextsecure tests running on windows
* Log when we get a blocked numbers sync message
* Save three old signed keys in addition to the current active
* Remove the mystery from all the error-related log messages
* Log successful load of signed key - to help debug prekey errors
* removeSignedPreKey: Don't hang or crash in error cases
* Log on top-level unhandled promise rejection
* Remove trailing comma in param list, Electron 1.6 does not like
* Harden top-level error handler for strange object shapes
* Retry failed signed key rotation; start rotation when registered (#1772)
* rotateSignedPrekeys: Fix 'res is not defined' error
* If the server rejects key rotation, don't retry immediately
* Force a signed key rotation on launch of any new version
* web requests: Don't fail if JSON not well-formed in error cases
Turns out that before our move to node-fetch, we ignored JSON.parse()
failures: https://github.com/WhisperSystems/Signal-Desktop/pull/1552/files#diff-1103a6aff0f28b6066715c6994278767L37518
* Update to libsignal v1.2.0, delete sessions on reset session
Previously we only archived sessions when sending or receiving a
'reset secure session, which didn't match up with the mobile apps.
I got a 413 (Rate limit exceeded) error from the server while fetching prekeys.
The client tried to parse the response as json since we expect json from the
prekey endpoint, which threw an exception because the response was not json.
This change prevents us from treating the response as json unless it has the
Content-Type header set accordingly.
If for some reason, the client and server disagree on whether the response
should be or is json, we'll default to treating it as text.
// FREEBIE
* Online/offline: Always stop timer, don't connect if closed
* Sockets: Send our own close event faster, shutdown only on close
Seems that we were too-aggressively disconnecting from all socket
events. Also, we should be able to send our own close event a lot
faster with no ill effects.
* Catch-up libtextsecure changes
* Use node-fetch instead of xhr
* Remove XMLHttpRequest.js
// FREEBIE
* Avoid calling json() on non json responses
Previously we would catch and swallow JSON parsing errors resulting from an
empty response, though empty responses are normal from a few endpoints, like
requesting sms or voice registration codes.
Since the JSON parsing call is now handled internally by node-fetch, we have to
keep closer track of our expected response type to avoid throwing an exception.
// FREEBIE
* Update to the latest version of autosize.js
* gitignore: Restrict 'dist' matches to the root dist folder
The global search for 'dist' caused problems when updateing bower
components.
* A couple minor version updates: ByteBuffer, filesize, intlTel
moment-with-localse, ProtoBuf
* Ensure that our preload.js setImmediate call finds right function
FREEBIE
* Our own socket close event, better logging, unregistration
FREEBIE
* Return CLOSED for NetworkStatusView if we've fully disconnected
* background.js: Remove messageReceiver = null, log in connect()

* Refactor delivery receipt event handler
* Rename the delivery receipt event
For less ambiguity with read receipts.
* Rename synced read event
For less ambiguity with read receipts from other Signal users.
* Add support for incoming receipt messages
Handle ReceiptMessages, which may include encrypted delivery receipts or read
receipts from recipients of our sent messages.
// FREEBIE

* Render read messages with blue double checks
* Send read receipts to senders of incoming messages
// FREEBIE
* Move ReadSyncs to their own file

// FREEBIE
* Add global setting for read receipts
Don't send read receipt messages unless the setting is enabled.
Don't process read receipts if the setting is disabled.
// FREEBIE
* Sync read receipt setting from mobile
Toggling this setting on your mobile device should sync it to Desktop. When
linking, use the setting in the provisioning message.
// FREEBIE
* Send receipt messages silently

* Fix conversation type in profile key update handling
// FREEBIE
* Set recipients on synced sent messages
* Render saved recipients in message detail if available
For older messages, where we did not save the intended set of recipients at the
time of sending, fall back to the current group membership.

* Record who a message has been delivered to
* Invert the not-clickable class
* Fix readReceipt setting sync when linking
* Render per recipient sent/delivered/read status
In the message detail view for outgoing messages, render each recipient's
individual sent/delivered/read status with respect to this message, as long as
there are no errors associated with the recipient (ie, safety number changes,
user not registered, etc...) since the error icon is displayed in that case.
*Messages sent before this change may not have per-recipient status lists
and will simply show no status icon.
// FREEBIE
* Add configuration sync request
Send these requests in a one-off fashion when:
1. We have just setup from a chrome app import
2. We have just upgraded to read-receipt support
// FREEBIE
* Expose sendRequestConfigurationSyncMessage
// FREEBIE
* Fix handling of incoming delivery receipts - union with array
FREEBIE
* Disconnect from socket faster on complete loss of network access
Today we wait for a keepalive request to fail; this change forces
disconnect in the case that the browser tells us that we're now offline.
FREEBIE
* MessageReceiver: don't react to errors after explicit close()
FREEBIE
Rather than throw an error, just log call messages and drop them. This way we
distinguish them from incorrectly encoded content messages or new types of
messages we don't support yet, and don't insert unnecessary red flags and
stacktraces in debug logs.
// FREEBIE
* Add AES-GCM encryption for profiles

* Translate failed authentication errors
When AES-GCM authentication fails, webcrypto returns a very generic error. The
same error is thrown for invalid length inputs, but our earlier checks in
decryptProfile should rule out those failure modes and leave us safe to assume
that we either had bad ciphertext or the wrong key.
// FREEBIE

Android will use a contact sync message to sync a profile key from Android
clients who have just upgraded and generated their profile key. Normally we
should receive this data in a provisioning message.
// FREEBIE
* Infer profile sharing from synced data messages
* Populate profile keys on outgoing messages
Requires that `profileSharing` be set on the conversation.
// FREEBIE
* Support for the profile key update flag
When receiving a message with this flag, don't init a message record, just
process the profile key and move on.
// FREEBIE

* Add certificate pinning on https service requests
Make https requests to the server using node apis instead of browser apis, so we
can specify our own CA list, which contains only our own CA.
This protects us from MITM by a rogue CA.
As a bonus, this let's us drop the use of non-standard ports and just use good
ol' default 443 all the time, at least for http requests.
// FREEBIE
* Make certificateAuthorities an option on requests
Modify node-based xhr implementation based on driverdan/node-XMLHttpRequest,
adding support for setting certificate authorities on each request.
This allows us to pin our master CA for requests to the server and cdn but not
to the s3 attachment server, for instance. Also fix an exception when sending
binary data in a request: it is submitted as an array buffer, and must be
converted to a node Buffer since we are now using a node based request api.
// FREEBIE
* Import node-based xhr implementation
Add a copy of https://github.com/driverdan/node-XMLHttpRequest@86ff70e, and
expose it to the renderer in the preload script.
In later commits this module will be extended to support custom certificate
authorities.
// FREEBIE
* Support "arraybuffer" responseType on requests
When fetching attachments, we want the result as binary data rather than a utf8
string. This lets our node-based XMLHttpRequest honor the responseType property
if it is set on the xhr.
Note that naively using the raw `.buffer` from a node Buffer won't work, since
it is a reuseable backing buffer that is often much larger than the actual
content defined by the Buffer's offset and length.
Instead, we'll prepare a return buffer based on the response's content length
header, and incrementally write chunks of data into it as they arrive.
// FREEBIE
* Switch to self-signed server endpoint
* Log more error info on failed requests
With the node-based xhr, relevant error info are stored in statusText and
responseText when a request fails.
// FREEBIE
* Add node-based websocket w/ support for custom CA
// FREEBIE
* Support handling array buffers instead of blobs
Our node-based websocket calls onmessage with an arraybuffer instead of a blob.
For robustness (on the off chance we switch or update the socket implementation
agian) I've kept the machinery for converting blobs to array buffers.

* Destroy all wacky server ports

On a recent trip through a CPU profile taken while Signal Desktop
churned through a large backlog of messages, it was clear that
console.log was a major source of time spent, primarily the sort
operation required after every new entry is added to the Backbone
collection. So, three different techniques to combat this:
1) Reduce the maximum number of entries in the collection from 5k to 2k
2) No more logging of add/update/remove queue in MessageReceiver
3) No more log entries in Message.handleDataMessage main codepath

When processing a contact sync with embedded identity key verification info, we
were running overlapping async fetch/save operations on the same conversation
model, causing a race that tends to clobber updates to the contact info.
In this change we extend the application-level contact info handler to block on
a subsequent call to the verification handler, which effectively serializes the
fetch/save calls, and relieves the need for the message receiver to trigger a
seperate event concerning the verification info on contact sync messages.
Fixes#1408
// FREEBIE
* Add support for backup and restore
This first pass works for all stores except messages, pending some scaling
improvements.
// FREEBIE
* Import of messages and attachments
Properly sanitize filenames. Logging information that will help with
debugging but won't threaten privacy (no contact or group names),
where the on-disk directories have this information to make things
human-readable
FREEBIE
* First fully operational single-action export and import!
FREEBIE
* Add migration export flow
A banner alert leads to a blocking ui for the migration. We close the socket and
wait for incoming messages to drain before starting the export.
FREEBIE
* A number of updates for the export flow
1. We don't immediately pop the directory selection dialog box, instead
showing an explicit 'choose directory' button after explaining what is
about to happen
2. We show a 'submit debug log' button on most steps of the process
3. We handle export errors and encourage the user to double-check their
filesystem then submit their log
4. We are resilient to restarts during the process
5. We handle the user cancelling out of the directory selection dialog
differently from other errors.
6. The export process is now serialized: non-messages, then messages.
7. After successful export, show where the data is on disk
FREEBUE
* Put migration behind a flag
FREEBIE
* Shut down websocket before proceeding with export
FREEBIE
* Add MigrationView to test/index.html to fix test
FREEBIE
* Remove 'Submit Debug Log' button when the export process is complete
FREEBIE
* Create a 'Signal Export' directory below user-chosen dir
This cleans things up a bit so we don't litter the user's target
directory with lots of stuff.
FREEBIE
* Clarify MessageReceiver.drain() method comments
FREEBIE
* A couple updates for clarity - event names, else handling
Also the removal of wait(), which wasn't used anywhere.
FREEBIE
* A number of wording updates for the export flow
FREEBIE
* Export complete: put dir on its own line, make text selectable

There's really no reason to retry encryption errors again if they've
already been made user-visible in a conversation.
Also, refactor e->error in background.js onError(), since both e and ev
in this method made it too easy to make a mistake.
