Going to http://sandbox.edit.io/?new=1 should open up a new page

[tcr]

Right now, going to sandbox.edit.io (or a locally running edit-text instance) will open up the document that corresponds to the requester's IP address, e.g. /welcome-127-0-0-1. This code lives in edit-server.rs:

edit-text/edit-server/src/bin/edit-server.rs

Lines 251 to 301 in 8bcb38a

	// Upload files using /?from={url}
	let load_doc = request.get_param("from")
	.ok_or(format_err!("no from parameter to download from")) // TODO what is this line for
	.and_then(|from| {
	// Create a randomly-named page ID for this page.
	id = random_id_alpha();
	// Download directly from URLs.
	// TODO is this irresponsible
	if from.starts_with("http") {
	let mut client = reqwest::Client::new();
	let mut res = client.get(&from).send()?;
	if !res.status().is_success() {
	bail!("Unsuccessful request")
	}
	let md = res.text()?;
	let doc = Doc(markdown_to_doc(&md)?);
	Ok(match validate_doc(&doc) {
	Ok(_) => doc,
	Err(err) => {
	eprintln!("Error decoding document: {:?}", err);
	Doc(doc_span![
	DocGroup({"tag": "pre"}, [
	DocChars("Error decoding document.", {Style::Normie => None}),
	]),
	])
	}
	})
	} else {
	// Interpret as a Markdown document
	let doc = Doc(markdown_to_doc(&from)?);
	Ok(match validate_doc(&doc) {
	Ok(_) => doc,
	Err(err) => {
	eprintln!("Error decoding document: {:?}", err);
	Doc(doc_span![
	DocGroup({"tag": "pre"}, [
	DocChars("Error decoding document.", {Style::Normie => None}),
	]),
	])
	}
	})
	}
	})
	.unwrap_or(default_doc());
	// Initialize the "hello world" post.
	eprintln!("creating helloworld post for {:?}", id);
	get_or_create_page_graphql(&id, &load_doc);
	return Response::redirect_302(format!("/{}", id));

We want to add another check just before this which looks to see if the parameter "new" exists, and if so, sets the id to a random value (using random_id_alpha). It should also set the document contents to default_doc(), so once it's generated there will be a basic document template for the user to edit.

Some expectations about how this works:

• ?new=1 would redirect to a random document id with the header "Welcome" and some accompanying text.
• If both new and from were supplied (e.g. ?new=1&from=markdown_content), we can assume that the "from" code will run last and take precedence.
• The behavior for http://sandbox.edit.io/?new=1 should be identical to going to the URL http://sandbox.edit.io/?from=https:, which (due to a quirk of the code right now) does the same thing.
