Steps to replicate the issue (include links if applicable):
Run this sample program:
use std::time::Duration;
use mwbot::parsoid::{Wikicode, WikinodeIterator};
use mwbot::{Bot, SaveOptions};
use tokio::time::sleep;
#[tokio::main(flavor = "current_thread")]
async fn main() {
let bot = Bot::from_default_config().await.unwrap();
let sandbox_title = "User:Count Count/sandbox";
let sandbox_page = bot.page(sandbox_title).unwrap();
let wikicode = sandbox_page.html().await.unwrap();
let mut wikitext = sandbox_page.wikitext().await.unwrap();
wikitext.push_str("\n* Test");
bot.page(sandbox_title)
.unwrap()
.save(wikitext, &SaveOptions::summary("Creating an edit conflict"))
.await
.unwrap();
let mutable_wikicode = wikicode.into_mutable();
mutable_wikicode.append(&Wikicode::new_text("Other Test"));
sleep(Duration::from_secs(2)).await;
sandbox_page
.save(mutable_wikicode, &SaveOptions::summary("Conflicting edit"))
.await
.unwrap();
}What happens?:
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: HttpError(reqwest::Error { kind: Status(404), url: Url { scheme: "https", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("en.wikipedia.org")), port: None, path: "/api/rest_v1/transform/html/to/wikitext/User%3ACount%20Count%2Fsandbox/1147476512", query: None, fragment: None } })', src/main.rs:26:10
`What should have happened instead?:
Getting an EditConflict error.
Software version (skip for WMF-hosted wikis like Wikipedia):
mwbot = "0.5.0-alpha.4"
tokio = { version = "1.26.0", features = [ "rt", "macros" ] }
Other information (browser name/version, screenshots, etc.):
1 sec is enough in my tests too.
I assume Parsoid removes the data associated with the render once a new version of a page is created and returns 404. I tested this without passing the ETag of the render in the if-match header but that does not work either. I wonder how the Visual Editor does this.
