This is now blocking https://github.com/simonw/datasette-graphql/issues/61 because that issue needs a way to turn off suggested facets when retrieving the results of a table query.

Enzo has a great solution here: https://twitter.com/enzo_mdd/status/1318685442976436226

Or maybe an option for a url. This keeps the CSV small but allows scripts to download binary data as needed.

In #1036 I'm planning on adding a way for users to access BLOB data. I can include that URL in the CSV output.

I think this plus the binary-CSV stuff in #1034 will justify a dedicated section of the documentation to talk about how Datasette handles binary BLOB columns.

I can also use a Content-Disposition header to force a download. I'm reasonably confident that the combination of Content-Disposition and X-Content-Type-Options: nosniff and application/binary will let me allow users to download the contents of arbitrary BLOB columns without any XSS risk.

https://security.stackexchange.com/questions/12896/does-x-content-type-options-really-prevent-content-sniffing-attacks says:

In Tangled Web Michal Zalewski says:

Refrain from using Content-Type: application/octet-stream and use application/binary instead, especially for unknown document types. Refrain from returning Content-Type: text/plain.

For example, any code-hosting platform must exercise caution when returning executables or source archives as application/octet-stream, because there is a risk they may be misinterpreted as HTML and displayed inline.

From https://hackerone.com/reports/126197:

archive.uber.com mirrors pypi. When downloading .tar.gz files from archive.uber.com, the MIME type is application/octet-stream. Injecting <html><script>alert(0)</script> into the start of the .tar.gz causes an XSS in Internet Explorer due to MIME sniffing.

So you do have to be careful not to open accidental XSS holes with application/octet-stream thanks to (presumably older) versions of IE.

From that thread it looks like the solution is to add a X-Content-Type-Options: nosniff header.

This feels good to me - it's consistent with how other features in Datasette work, and it means users who need the binary data in CSV (for whatever reason) can get it if they want to.

New idea: since binary in CSV doesn't make sense anyway, emulate Datasette's HTML UI default and output this:

id,title,data
1,Some title,<Binary data: 14 bytes>
2,Other title,<Binary data: 57 bytes>

Then allow users to add ?_base64=1 to the URL to get base64 instead https://twitter.com/simonw/status/1318679950635888641

I could go with the same format as datasette-render-binary but using 0x00 as the format for the hex bytes.

0x15 0x1C 0x02 0xC7 JFIF 0x00 0x01

Problem with this is that it's ambiguous: if the ASCII characters 0x15 occur in the text they will be indistinguishable from those hex bytes.

But since representing binary data in CSV fundamentally doesn't make sense I'm not sure if that really matters.

I think it's worth having a plugin hook for this - it can be same hook that is used internally. Maybe register_extra - it lets you return one or more extra implementations, each with a name and an async function that gets called.

Things like suggested facets will become register_extra hooks. Maybe actual facets too?

In the documentation for ?_extra= I think I'll emphasize the comma-separated version of it. Also: there will be ?_extra= values which act as aliases for collection combinations - e.g. ?_extra=full will toggle everything.

I think this all comes down to how the ?_extras= mechanism works (see #262), as first hinted at in a30c5b220c15360d575e94b0e67f3255e120b916 (see commit message) when I added this long-forgotten undocumented feature: https://latest.datasette.io/fixtures/attraction_characteristic/2.json?_extras=foreign_key_tables

Extras need to be able to execute additional SQL, since that would solve the problem we have now where the expensive "suggested facets" code runs on all .json output even when its results are not being shown.

That renderers[key] = path_with_format( is in a base class which can be used for both arbitrary queries, canned queries and the table view. I think that's OK, but it means that the format="json" argument on datasette.urls.table() won't be used by Datasette internally, it will just be available for plugins.

That datasette.urls.table("db", "table") + ".json" example is bad because if the table name contains a . it should be ?_format=json instead.

Maybe .table() should have a format="json" option that knows how to do this.

Reconsidering this: I think the .get() etc methods should automatically add the base_url prefix for you, since these APIs are only intended to make internal calls.

The clincher on this is when I went to add a section to the datasette.client documentation recommending you use datasette.urls.path() for every call to them that you make.

But there's a problem: to handle table name escaping users are likely to want to use datasette.urls.table() anyway, like this:

response = await datasette.client.get(datasette.urls.table("db", "table") + ".json")

This risks adding the base_url prefix twice. Maybe the .table() method could return a string-like object that is marked as already having the base_url prefix added, so the client.get() method knows not to add it again.

Here is one quick sketch (done in Figma :P) for an idea: a possible filter to switch between showing all tables from all databases, or grouping tables by database.

(the switch is interactive)

All tables: https://www.figma.com/proto/BjFrMroEtmVx6EeRjvSrox/Datasette-test?node-id=1%3A2&viewport=536%2C348%2C0.5&scaling=min-zoom

When only 1 database: https://www.figma.com/proto/BjFrMroEtmVx6EeRjvSrox/Datasette-test?node-id=1%3A162&viewport=536%2C348%2C0.5&scaling=min-zoom

Is this is useful, I can send some more suggestions/sketches.

We have a solution for this now: datasette.urls from #1033 can be used by plugins to assemble the correct URLs to pass to .get() and friends.

OK, I've made a ton of improvements to how the base_url setting works - see tickets linked from #1023. I've just pushed out an alpha release with those changes in it: https://github.com/simonw/datasette/releases/tag/0.51a0

@tsibley @tballison @ChristopherWilks I'd really appreciate your help testing this alpha!

You can install it with:

pip install datasette==0.51a0

It should work with just ProxyPass, without needing the ProxyPassReverse setting.

Great point about CORS, I hadn't considered that.

I think I'm going to keep the Link: header (added in #1014) because I quite enjoy using it with GitHub and WordPress, but I'm not going to have it be the default way of doing pagination. For the default shape I'm now leaning towards this:

json { "total": 36, "rows": [{"id": 1, "name": "Cleo"}], "next_url": "https://latest-with-plugins.datasette.io/fixtures/facetable.json?_next=5" }

So three keys: total, rows and next_url. Then extra keys can be added using ?_extra= with various named bundles.

The datasette-render-binary plugin does this, which I really like - but without the different coloured fonts I'm not sure how readable it would be as just plain text:

Really the goal here is to find the most human-friendly option, so that people looking at the output have a vague idea what's going on. That's why I'm not leaping at the chance to use base64.

Changed my mind, error.html needs access to urls in order to link to its CSS file. Passing it after all (it already got passed ds.config("base_url") so ds was available previously).

I vote against headers. It has a lot of strikes against it: poor discoverability, new developers often don’t know how to use them, makes CORS harder, makes it hard to use eg with JQ, needs ad hoc specification for each bit of metadata, etc.

The only advantage of headers is that you don’t need to do .rows, but that’s actually good as a data validation step anyway—if .rows is missing assume there’s an error and do your error handling path instead of parsing the rest.

I fixed the queries.html one. I'm not going to fix these two: datasette/templates/error.html: <a href="/">home</a> datasette/templates/patterns.html: <a href="/">home</a> / Because the error.html one does not get passed a context (which makes sense since an error has occurred) and the pattern portfolio doesn't need to link to anywhere in particular.
