If I want to avoid counting virtual tables, I need to detect which tables are virtual tables.
The safest way to do this is probably to pull the `sql` for every table and then, in Python, check for values that start with `create virtual table` after converting to lower case, using any number of spaces.
This would catch things like ` CREATE virtual TABLE` which might be missed by a SQL `like` query. ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",837308703,

fp.write((""{}: {}\n"".format(sql, params)).encode(""utf-8""))
cursor.execute(sql, params if params is not None else {})

I had to use `ab` binary mode because Python doesn't allow `buffering=0` for non-binary file operations.
With the log enabled, I used `docker exec -it 589ae68de943 bash` to attach to the running container and `tail -f /tmp/sql.log` to see the logs. Here's where it broke:
```
select count(*) from [idx_civici_geom_parent]: None
select count(*) from [sqlite_stat1]: None
select count(*) from [sqlite_stat3]: None
select count(*) from [SpatialIndex]: None

I had to use `--privileged` here because otherwise `gdb` showed a ""Could not attach to process"" error.
```
docker exec --privileged -it 16197781a7b5 bash

A huge amount of stuff scrolls past as Datasette starts up, since we are tracing every executed line of Python.
After about a minute it's finished starting and gets to this point:
```
selectors.py(452): if timeout is None:
selectors.py(454): elif timeout <= 0:
selectors.py(459): timeout = math.ceil(timeout * 1e3) * 1e-3
selectors.py(464): max_ev = max(len(self._fd_to_key), 1)
selectors.py(466): ready = []
selectors.py(467): try:

```
Now I can make some HTTP requests against it.

Copying from my private notes:
> Use the lazy evaluated DI mechanism to break up table view into different pieces eg for faceting
>
> Use that to solve JSON vs HTML views
>
> Oh here's an idea: what if the various components of the table view were each defined as async functions.... and then executed using asyncio.gather in order to run the SQL queries in parallel? Then try benchmarking with different numbers of threads?
>
> The async_call_with_arguments function could do this automatically for any awaitable dependencies
>
> This would give me massively parallel dependency injection
>
> (I could build an entire framework around this and call it c64)
>
> Idea: arguments called eg ""count"" are executed and the result passed to the function. If called count_fn then a reference to the not-yet-called function is passed instead
>
> I'm not going to completely combine the views mechanism and the render hooks. Instead, the core view will define a bunch of functions used to compose the page and the render hook will have conditional access to those functions - which will otherwise be asyncio.gather executed directly by the HTML page version
>
> Using asyncio.gather to execute facets and suggest facets in parallel would be VERY interesting
>
> suggest facets should be VERY cachable - doesn't matter if it's wrong unlike actual facets themselves
>
> What if all Datasette views were defined in terms of dependency injection - and those dependency functions could themselves depend on others just like pytest fixtures. Everything would become composable and async stuff could execute in parallel
>
> FURTHER IDEA: use this for the ?_extra= mechanism as well.
>
> Any view in Datasette can be defined as a collection of named keys. Each of those keys maps to a function or an async function that accepts as input other named keys, using DI to handle them.
>
> The HTML view is a defined function. So are the other outputs.
>
> Default original inputs include “request” and “datasette”.
>
> So… maybe a view function is a class methods that use DI. One of those methods as an .html() method used for the default page.
>
> Output formats are a bit more complicated because they are supposed to be defined separately in plugins. They are unified across query, row and table though.

https://global-power-plants.datasettes.com/global-power-plants/global-power-plants?_facet=country_long&_facet=primary_fuel&_trace=1&_size=0 shows those facets with size=0 on the SQL query - and shows a SQL trace at the bottom of the page.
The country_long facet query takes 45.36ms, owner takes 38.45ms, primary_fuel takes 49.04ms - so a total of 132.85ms
That's against https://global-power-plants.datasettes.com/-/versions says SQLite 3.27.3 - so even on a SQLite version that doesn't materialize the CTEs there's a significant performance boost to doing all three facets in a single CTE query.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",830567275,

It looks like this optimization is completely unavailable on SQLite prior to 3.35.0 (released 12th March 2021).

So it could it be that `_parsedate_tz` is having trouble with that `Mon, 28 Aug 2006 08:14:08 +0200 (Westeurop�ische Sommerzeit)` string.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",813880401,

```python
elif message.get_content_type() == ""text/plain"":
body = message.get_payload(decode=True)

So presumably that decodes to a unicode string?
I imagine the reason the column is a `BLOB` for me is that `sqlite-utils` determines the column type based on the first batch of items - https://github.com/simonw/sqlite-utils/blob/09c3386f55f766b135b6a1c00295646c4ae29bec/sqlite_utils/db.py#L1927-L1928 - and I got unlucky and had something in my first batch that wasn't a unicode string.

It would be useful if those warnings told me the message ID (or similar) of the affected message so I could grep for it in the `mbox` and see what was going on.

It can be a bit of a convoluted pattern, and I'm not at all sure it would work for `mbox` files since it looks like that library has other reasons it needs to do a file scan rather than streaming it through one chunk of bytes at a time.
