This was caused by the fact that the canPost property was not exposed from the ChatItem model.
I'm actually not sure why it didn't show an error trying to call a function that doesn't exist
When contract addresses that are not ERC-20 or ERC-721 were input, the token would be allowed to be added and would crash the app.
In addition, when an ERC-20 contract was deployed without a name and symbol, “Invalid ERC-20 address” would appear.
This PR adds error checking from the token detail lookup and reports the error back to the user in the modal. This prevents non-ERC-20/721 contracts from being able to be added to the app and prevents a crash.
Two fake messages are usually added to chat message lists inside a channel or
chat:
- One that imitates a chat identifier
- one that creates a button to fetch older messages
These two fake messages are added so it's ensured they show up at the beginning
of the chat.
The status timeline is also just a list of messages (filtered by a certain message
type), however there's no need to render these fake messages in this scenario.
That's why a `addFakeMessages` flag has been introduced which conditionally adds
those fake messages here: https://github.com/status-im/status-desktop/commit/3f012dbf0#diff-6aa545137319516beb03623bc6a9750e1d14a40c68d8868b5a672320fc4d680aR69
At some point, possibly around here (https://github.com/status-im/status-desktop/commit/8ee5abe57), the fake message for
the fetch more button has been reintroduced as default fake message.
This commit puts it back into the function so that it doesn't show up
inside the timeline view.
refactor: move threadpool task declarations inline with views

There was a bug introduced https://github.com/status-im/status-desktop/commit/2ac67f95a where we'd rely on the
possibly resolved public key, which is passed to `generateAlias()`.
The public key is never guaranteed to be an actual key (if resolution fails,
it's a an empty string). Passing an empty string to `generateAlias()` causes
`status-go` to crash and we don't handle that error.
This commit ensures that we only attempt to generate an alias when we
indeed have a successfully resolved public key.
Move the remaining stickers spawnAndSend (obtainAvailableStickerPacks) into a threadpool task.
refactor: create a base class for tasks models to inherit from
NOTE: this branch is based off of `experiment/tasks-3` and should be rebased on master once that branch is merged.
The `TaskManager` threadpool is a memory-safe replacement for the `spawnAndSend` operations that are currently causing memory issues in status-desktop.
From a fundamental memory management point of view, `libstatus/settings`, `libstatus/contracts`, and `libstatus/tokens` (custom tokens) have all been converted to `{.threadvar.}`s and `Atomic[bool]`s to maintain the cache and `dirty` flag across threads, respectively, eliminating the need for thread locks and incorrect `{.gcsafe.}` compiler overrides.
The successful [recyclable threadpool experiment from `nim-task-runner`](https://github.com/status-im/nim-task-runner/blob/test/use-cases/test/use_cases/test_sync.nim) using `AsyncChannel[ThreadSafeString]`s was brought over to `status-desktop` and implemented in somewhat of a hardcoded manner, as we knew this would save some time instead of trying to create a fully fleshed out `nim-task-runner` API and build a miraculous macro that may or may not be able to generate the needed API.
The threadpool is started by the `TaskManager` and both the `TaskManager` and the `TaskManager`'s threadpool are started as early as possible in the application lifecycle (in `nim_status_client.nim`). The `TaskManager` creates a thread to run the threadpool. During its initialization, the threadpool then spools up all the threads it will manage and puts them in an idle thread sequence. This is to prevent expensive thread creation and teardown happening during the app's lifetime as it is quite expensive and blocks the main thread. When tasks comes in to the pool, the task is sent to an idle thread, or put in a queue if all threads are busy. The idle thread is moved to the busy thread sequence. When a task is completed, the thread is taken out of the busy threads sequence and moved back in to the sequence of idle threads, effectively recycling it.
The first `spawnAndSend` we were able to change over to the new threadpool was `estimate`, which estimates the gas of a sticker purchase transaction.
From the consumer point of view, the existing `spawnAndSend` to achieve this looks like:
```nim
proc estimate*(self: StickersView, packId: int, address: string, price: string, uuid: string) {.slot.} =
let status_stickers = self.status.stickers
spawnAndSend(self, "setGasEstimate") do:
var success: bool
var estimate = status_stickers.estimateGas(packId, address, price, success)
if not success:
estimate = 325000
let result: tuple[estimate: int, uuid: string] = (estimate, uuid)
Json.encode(result)
```
And the new syntax looks like this:
```nim
proc estimate*(self: StickersView, packId: int, address: string, price: string, uuid: string) {.slot.} =
self.status.taskManager.threadPool.stickers.stickerPackPurchaseGasEstimate(cast[pointer](self.vptr), "setGasEstimate", packId, address, price, uuid)
```
The logic inside the `spawnAndSend` body was moved to [src/status/tasks/stickers.nim](https://github.com/status-im/status-desktop/compare/experiment/tasks-3?expand=1#diff-09e57eef00b0cee5c4abdb9039f948d8372e7003e09e934a9b4c7e9167d47658).
This is just the first migration of `spawnAndSend`, however moving the majority of the remaining `spawnAndSend`s will likely just be an exercise in copy/pasta. There will be one or two that may require a bit more thinking, depending how they rely on data from the model.
Once the `spawnAndSend`s have been converted to the threadpool, we can start implementing the [long-running process from the task runner use case experiments](https://github.com/status-im/nim-task-runner/blob/test/use-cases/test/use_cases/test_long_running.nim).
And finally, we can then implement the [async tasks](https://github.com/status-im/nim-task-runner/blob/test/use-cases/test/use_cases/test_async.nim) if needed.
@michaelsbradleyjr and I spent many hours digging in to the depths of nim's memory management in an attempt to understand it. We have created [a presentation with our task runner experiment findings](https://docs.google.com/presentation/d/1ItCxAfsVTcIoH_E4bgvmHljhbU-tC3T6K2A6ahwAedk/edit?usp=sharing), and @michaelsbradleyjr has spent time [answering questions off the back of that presentation.](https://gist.github.com/michaelsbradleyjr/1eaa9937b3fbb4ffff3fb814f0dd82a9).
We have created a fork of `edn.nim` at `status-im/edn.nim` and we need the PR to be merged and the commit hash updated before we can merge this PR in to `status-desktop`.
We've introduced a regression in https://github.com/status-im/status-desktop/commit/f1e83f74b#diff-f35edd413addd14c1f81816d6b5ee2bcbdf85fa0e3295d324cb78c98e26d4327L364 where we check whether an RPC's `error` is `null`
and its `result` is not `null`.
This breaks the application with an illegal storage access,
as in case of a successful API call, the response will have only a `result` key
(even when it's `null`).
Since we haven't done anything with a possible `error` in the reponse even before
that change was made, this commit removes the `error` check and safe guards around
whether `result` exists.
Fixes#2062
Allow up to 5 images to be dragged and dropped in to one-on-one chats and in the timeline. Can be combined with the existing upload button. The upload file dialog has been changed to allow multiple selections. Drag and dropped images adhere to the following rules, with corresponding validations messages:
- Max 5 image
- Image size must be 0.5 MB or less
- File extension must be one of [".png", ".jpg", ".jpeg", ".heif", "tif", ".tiff"]
Drag and drop and uploaded images are now also deduplicated.
Prior to this commit, communities without an image would render invisible
in the navigation bar of the application. To avoid this, we're now falling
back to our StatusLetterIdenticon component, which renders the first letter
of the community name with the color of the community.
