I start with new python3 verison 3.12.0 Also have the error where connect DataBase

Traceback (most recent call last): File "/home/t/Development/python/FKPJ/ClinicSYS/run.py", line 1, in <module> import re, os, io, json, sqlite_utils, requests, pytz, logging File "/home/t/.local/lib/python3.12/site-packages/sqlite_utils/__init__.py", line 1, in <module> from .db import Database File "/home/t/.local/lib/python3.12/site-packages/sqlite_utils/db.py", line 277, in <module> class Database: File "/home/t/.local/lib/python3.12/site-packages/sqlite_utils/db.py", line 306, in Database filename_or_conn: Optional[Union[str, pathlib.Path, sqlite3.Connection]] = None, ^^^^^^^^^^^^^^^^^^ This bug come from sqlite-utils since's v3.33. Anyone get the same ?

As well now of the resolved plan just keep the sqlite-utils version in python3.12 with v3.32.1 [tested] but where are the sqlite3.Connection problem....

This won't happen on python version down to 3.11[tested] Just the python3.12.0, I have test this error are come from the sqlite3 connection The error say from sqlite_utils and with the sqlite3 Connection, what can I do.

Let fix together.

I'm currently working on a new feature for Hypothesis, where we can dump a tidy jsonlines table of all the test cases we tried - including arguments, outcomes, timings, coverage, etc. Exploring this seems like a perfect cases for sqlite-utils and datasette, but I pretty quickly ran into an integer overflow problem and don't want to recommend that experience to my users.

I originally went to report this as a bug... and then found https://github.com/simonw/sqlite-utils/issues/309#issuecomment-895581038 almost exactly matched my repro 😅

https://github.com/simonw/sqlite-utils/issues/110#issuecomment-626391063 suggests that using NUMERIC would avoid this overflow error, although "If the TEXT value is a well-formed integer literal that is too large to fit in a 64-bit signed integer, it is converted to REAL." suggests that this would come at the cost of rounding to the nearest float value. Maybe I should just convert large integers to float before writing out my json?

After a bit more hacking, "manually cast large integers to float" seems like a decent solution for my particular case, but having written it up I thought I might as well post this issue anyway - I hope it's useful feedback, and won't mind at all if you close as wontfix if it's not.

I'm starting this issue without a clear reproduction in case someone else has seen this behavior, and to use the issue as a notebook for research.

I'm using Datasette with the SWITRS data set, which is a California Highway Patrol collection of traffic incident data from the past decade or so. I receive data from them in CSV and want to work with it in Datasette, then export it to CSV for mapping in Felt.com.

Their data makes extensive use of codes for incident column data (1 for Monday and so on), some of it integer codes and some of it letter/text codes. The text codes are sometimes blank or -. During import, I'm creating lookup tables for foreign key references to make the Datasette UI presentation of the data easier to read.

If I import the data and set up the integer foreign keys, everything works fine, but if I set up the text foreign keys, CSV export starts to fail.

The foreign key configuration is as follows:

```

Some tables use integer ids, like sensible tables do. Let's import them first

since we favor them.

for TABLE in DAY_OF_WEEK CHP_SHIFT POPULATION SPECIAL_COND BEAT_TYPE COLLISION_SEVERITY do sqlite-utils create-table records.db $TABLE id integer name text --pk=id sqlite-utils insert records.db $TABLE lookup-tables/$TABLE.csv --csv sqlite-utils add-foreign-key records.db collisions $TABLE $TABLE id sqlite-utils create-index records.db collisions $TABLE done

Other tables use letter keys, like they were raised by WOLVES. Let's put them

at the end of the import queue.

for TABLE in WEATHER_1 WEATHER_2 LOCATION_TYPE RAMP_INTERSECTION SIDE_OF_HWY \ PRIMARY_COLL_FACTOR PCF_CODE_OF_VIOL PCF_VIOL_CATEGORY TYPE_OF_COLLISION MVIW \ PED_ACTION ROAD_SURFACE ROAD_COND_1 ROAD_COND_2 LIGHTING CONTROL_DEVICE \ STWD_VEHTYPE_AT_FAULT CHP_VEHTYPE_AT_FAULT PRIMARY_RAMP SECONDARY_RAMP do sqlite-utils create-table records.db $TABLE key text name text --pk=key sqlite-utils insert records.db $TABLE lookup-tables/$TABLE.csv --csv sqlite-utils add-foreign-key records.db collisions $TABLE $TABLE key sqlite-utils create-index records.db collisions $TABLE done ```

You can see the full code and import script here: https://github.com/radical-bike-lobby/switrs-db

If I run this code and then hit the CSV export link in the Datasette interface (the simple link or the "advanced" dialog), export fails after a small number of CSV rows are written. I am not seeing any detailed error messages but this appears in the logging output:

``` INFO: 127.0.0.1:57885 - "GET /records/collisions.csv?_facet=PRIMARY_RD&PRIMARY_RD=ASHBY+AV&_labels=on&_size=max HTTP/1.1" 200 OK Caught this error:

```

(No other output follows error: other than a blank line.)

I've stared at the rows directly after the error occurs and can't yet see what is causing the problem. I'm going to set up a development environment and see if I get any more detailed error output, and then stare more at some problematic lines to see if I can get a simple reproduction.

At the bottom of database pages, datasette gives users the opportunity to download the underlying sqlite database. It would be great if that could be served gzip compressed.

this is similar to #1213, but for me, i don't need datasette to compress html and json because my CDN layer does it for me, however, cloudflare at least, will not compress a mimetype of "application"

(see list of mimetype: https://developers.cloudflare.com/speed/optimization/content/brotli/content-compression/)

When a column named 'value' is included there are no suggested facets is shown as the query uses an alias of 'value'.

https://github.com/simonw/datasette/blob/452a587e236ef642cbc6ae345b58767ea8420cb5/datasette/facets.py#L168-L174

Currently the following is shown (from https://latest.datasette.io/fixtures/facetable)

When I add a column named 'value' only the JSON facets are processed.

I think that not using aliases could be a solution (except if someone wants to use a column named count(*) though this seems to be unlikely). I'll open a PR with that.

There is also a TODO with a similar question in the same file. I have not looked into that yet.

Initially, I found an issue in datasette where it wouldn’t find spatialite when running on my Radxa Rock 5B - an RK3588 powered SBC, running the arm64 build of Debian Bullseye. I confirmed the same behaviour on my Raspberry Pi 4 - a BCM2711 powered SBC, running the arm64 build of Debian Bookworm.

$ datasette --load-extension=spatialite example.db Error: Could not find SpatiaLite extension

I did some digging and realised the issue originates in this project. Even with the libsqlite3-mod-spatialite package installed, pytest skips all of the GIS tests in the project.

``` $ apt list --installed | grep spatial […] libsqlite3-mod-spatialite/stable,now 5.0.1-3 arm64 [installed]

I tracked the issue down to the find_sqlite() function in the utils.py file. The SPATIALITE_PATHS array doesn’t have an entry for the location of this module on arm64 linux.

Hi ! I noticed that when I am trying to use the delete method of the Table object, the record get properly deleted from the table, but the cascading delete triggers on foreign keys do not activate.

self.db["contact"].delete(contact_id)

I tried querying the database directly via DB Browser and the triggers work without any issue. Looked up the source code and behind the scene this method is just querying the database normally so I'm not exactly sure where this behavior comes from.

Thank you in advance for your time !

Currently the constructor accepts memory=True or memory_name=... and uses those to create a connection, but does not record what those values were:

This makes it hard to tell if a database object is to an in-memory or a file-based database, which is sometimes useful to know.

I've used this pattern twice now: https://til.simonwillison.net/datasette/register-new-plugin-hooks - in datasette-graphql and datasette-low-disk-space-hook. I should describe the pattern on https://docs.datasette.io/en/stable/writing_plugins.html

The BaseView class has a method for cascading permission checks, but it's not easily accessible to plugins.

https://github.com/simonw/datasette/blob/5eb8e9bf250b26e30b017d39a392c33973997656/datasette/views/base.py#L75-L99

This leaves plugins like datasette-graphql having to implement their own versions of this logic, which is bad: https://github.com/simonw/datasette-graphql/issues/65

First check view-database - if that says False then disallow access, if it says True then allow access. If it says None check view-instance.

This should become a supported API that plugins are encouraged to use.

Discussed with Alex this morning. We think the American spelling is fine here (it's shorter than catalogue) and that it's a slightly less lazy name than core_.

This change updates the -s/--setting option to datasette serve to allow it to be used to set arbitrarily complex nested settings in a way that is compatible with the new -c datasette.yml work happening in: - #2143

It will enable things like this: datasette data.db --setting plugins.datasette-ripgrep.path "/home/simon/code" For the moment though it just affects settings - so you can do this: datasette data.db --setting settings.sql_time_limit_ms 3500 I've also implemented a backwards compatibility mechanism, so if you use it this way (the old way): datasette data.db --setting sql_time_limit_ms 3500 It will notice that the setting you passed is one of Datasette's core settings, and will treat that as if you said settings.sql_time_limit_ms instead.

This came up working on this feature: - https://github.com/simonw/llm/pull/186

I have a table with this schema: sql CREATE TABLE [collections] ( [id] INTEGER PRIMARY KEY, [name] TEXT, [model] TEXT ); CREATE UNIQUE INDEX [idx_collections_name] ON [collections] ([name]); So the primary key is an integer (because it's going to have a huge number of rows foreign key related to it, and I don't want to store a larger text value thousands of times), but there is a unique constraint on the name - that would be the primary key column if not for all of those foreign keys.

Problem is, fetching the collection by name is actually pretty inconvenient.

Fetch by numeric ID:

python try: table["collections"].get(1) except NotFoundError: # It doesn't exist Fetching by name: python def get_collection(db, collection): rows = db["collections"].rows_where("name = ?", [collection]) try: return next(rows) except StopIteration: raise NotFoundError("Collection not found: {}".format(collection)) It would be neat if, for columns where we know that we should always get 0 or one result, we could do this instead: python try: collection = table["collections"].get(name="entries") except NotFoundError: # It doesn't exist The existing .get() method doesn't have any non-positional arguments, so using **kwargs like that should work:

https://github.com/simonw/sqlite-utils/blob/1260bdc7bfe31c36c272572c6389125f8de6ef71/sqlite_utils/db.py#L1495

Figure out how that should work once I've refactored those classes to view functions instead.

While using sqlite-utils convert I realized it would be handy if you could pass --pdb to have it open the debugger at the first instance of a failed conversion.

The idea here is that hitting /content without a ?sql= will show an empty result set AND default to including a bunch of extras about the list of tables in the database.

Then I won't have to think about /content and /content?sql= as separate pages any more.

Hi, I'm trying to have a display function in Dogsheep's config.yml that includes something like this:

```

{{ display.title }} (source)

{{ display.snippet|safe }}

```

Unfortunately, rendering fails with a message 'urls is undefined'.

The same happens if I'm trying to build a row URL manually, using filters like quote_plus (as my keys are URLs).

Any hints?

Thanks!

Also need a design for an option for the .transform() method to indicate that the new table should be created with a new name without dropping the old one.

I think keep_table="name_of_table" is good for this.

For every command/API method there should be a link to the equivalent in the other form factor.

Maybe also link to the API and CLI reference pages too.

The former datasette-insert plugin had an option ?alter=1 to auto-add new columns. Does the JSON write API also have this?

CSV files with empty cells in (which come through as the empty string) are common and a bit gross.

Having an option that means "and if it's an empty string store null instead) would be cool.

I brainstormed name options here https://chat.openai.com/share/c947b738-ee7d-419c-af90-bc84e90987da

Aside: this makes me think it might be cool if sqlite-utils had a way of working with dataclasses rather than just dicts, and knew how to create a SQLite table to match a dataclass and maybe how to code-generate dataclasses for a specific table schema (dynamically or even using code-generation that can be written to disk, for better editor integrations).

I found myself wanting to insert rows from a 849MB CSV file without processing the whole thing: https://huggingface.co/datasets/jerpint-org/HackAPrompt-Playground-Submissions/tree/main

sqlite-utils prints \r\n but it should probably print \n (unless the platform is detected as Windows?)

It has tripped me up a few times when piping the output of sqlite-utils to other programs:

$ sqlite-utils --no-headers --csv ~/lb/fs/d.db 'select path from media limit 1' | cat -A /mnt/d7/file^M$ $ sqlite-utils --no-headers --csv ~/lb/fs/d.db 'select path from media limit 1' | tr -d '\r' | cat -A /mnt/d7/file$

Hi! this might be a question related to both SQLite & sqlite-utils, and you might be more experienced with them.

I have a large bunch of ids, and I'm wondering which is the best way to query them in terms of performance, and simplicity if possible.

The naive approach would be something like select * from table where rowid in (?, ?, ?...) but that wouldn't scale if ids are >1k.

Another approach might be creating a temp table, or in-memory db table, insert all ids in that table and then join with the target one.

I failed to attach an in-memory db both using sqlite-utils, and plain sql's execute(), so my closest approach is something like,

python def filter_existing_video_ids(video_ids): db = get_db() # contains a "videos" table db.execute("CREATE TEMPORARY TABLE IF NOT EXISTS tmp (video_id TEXT NOT NULL PRIMARY KEY)") db["tmp"].insert_all([{"video_id": video_id} for video_id in video_ids]) for row in db["tmp"].rows_where("video_id not in (select video_id from videos)"): yield row["video_id"] db["tmp"].drop()

That kinda worked, I couldn't find an option in sqlite-utils's create_table() to tell it's a temporary table. Also, tmp table is not dropped finally, neither using .drop() despite being created with the keyword TEMPORARY. I believe it should be automatically dropped after connection/session ends though I read.

I'm trying to use sqlite-utils to data generated incrementally. There are a few aspects of this that I don't currently know how to handle. I would like an option to apply writes incrementally, line-by-line as they are received. I would like an option to echo incremental progress. And, it would be nice to have

In particular, I'm using CoreLocationCLI -w -j to generate, newline-delimited JSON.

One variant of the command

stdbuf -oL CoreLocationCLI -w -j | pee 'sqlite-utils insert loc.db loc -' nl

pee, from moreutils, is like tee but spawns and pipes to the processes created by invoking each of its arguments, so, for gratuitous demonstration, pee 'sponge out.log' cat would behave like tee.

It looks like I can get what I want with: stdbuf -oL CoreLocationCLI -w -j | while read line; do <<<"$line" sqlite-utils insert loc.db loc -; echo "$line"; done | nl

I believe this is related to https://github.com/simonw/sqlite-utils/issues/98.

When pk is specified by table A's insert call, it throws an index error if a different table has written a row with a higher rowid than exists in the first table. Here's a basic example:

```py from sqlite_utils import Database

def test_pk_for_insert(fresh_db): user = {"id": "abc", "name": "david"}

fresh_db["users"].insert(user, pk="id")

fresh_db["comments"].insert_all(
    [
        {"id": "def", "text": "ok"},
        {"id": "ghi", "text": "great"},
    ],
)

fresh_db["users"].insert(
    user,
    ignore=True,
    # BUG: when specifying pk on the second insert call 
    # db.py goes into a block it doesn't expect and we get the error
    pk="id",
)

if name == "main": db = Database("bug.db") if db["users"].exists(): raise ValueError( "bug only shows on a new database - remove bug.db before running the script" ) test_pk_for_insert(db) ```

The error is:

py File "/Users/david/projects/reddit-to-sqlite/.venv/lib/python3.11/site-packages/sqlite_utils/db.py", line 2960, in insert_chunk row = list(self.rows_where("rowid = ?", [self.last_rowid]))[0] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^ IndexError: list index out of range

The issue is in this block:

https://github.com/simonw/sqlite-utils/blob/2747257a3334d55e890b40ec58fada57ae8cfbfd/sqlite_utils/db.py#L2954-L2958

relevant locals are:

• pk: 'id'
• result.lastrowid: 2

What's most interesting is the comment # self.last_rowid will be 0 if a "INSERT OR IGNORE" happened, which doesn't seem to be the case here.

This will probably work for bash:

eval "$(_SQLITE_UTILS_COMPLETE=bash_source sqlite-utils)"

Need to add this to the installation docs here: https://sqlite-utils.datasette.io/en/stable/installation.html - along with the pattern for adding that to .zshrc or whatever.

Noticed this while testing: - #547

If you pass a non-existent column to -c/--column you don't get an error message.

Noticed this:

``` % sqlite-utils analyze-tables content.db repos -c delete_branch_on_merge --common-limit 20 --no-least repos.delete_branch_on_merge: (1/1)

Total rows: 158 Null rows: 158 Blank rows: 0

Distinct values: 0

Most common: 158: None ```

The 158: None there is duplicate information considering we already know there are 158/158 null rows.

This fixes #514 by making the initial insert for upserts include all columns, so that new rows can be added to tables with non-pkey columns that have constraints.

(aside: I'm not a python programmer. pip? pipenv? venv? These are mystical incantations to me. The process to set up this repo for local development and testing was so easy. Thank you for the excellent contributing documentation!)

Fixes #509, Fixes #336

Thanks for the great library! I fixed a bug that sqlite-utils transform breaks DEFAULT values. All tests already present passed with no changes, and I added some tests for this PR.

In #509 case, fixed here.

```shell $ sqlite3 test.db << EOF CREATE TABLE mytable ( col1 TEXT DEFAULT 'foo', col2 TEXT DEFAULT (STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW')) ) EOF

$ sqlite3 test.db "SELECT sql FROM sqlite_master WHERE name = 'mytable';" CREATE TABLE mytable ( col1 TEXT DEFAULT 'foo', col2 TEXT DEFAULT (STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW')) )

$ sqlite3 test.db "INSERT INTO mytable DEFAULT VALUES; SELECT * FROM mytable;" foo|2022-12-21 01:15:39.669

$ sqlite-utils transform test.db mytable --rename col1 renamedcol1 $ sqlite3 test.db "SELECT sql FROM sqlite_master WHERE name = 'mytable';" CREATE TABLE "mytable" ( [renamedcol1] TEXT DEFAULT 'foo', [col2] TEXT DEFAULT (STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW')) # ← Non-String Value )

$ sqlite3 test.db "INSERT INTO mytable DEFAULT VALUES; SELECT * FROM mytable;" foo|2022-12-21 01:15:39.669 foo|2022-12-21 01:15:56.432 ```

And #336 case also fixed. Special values are described here.

3.2. The DEFAULT clause ... A default value may also be one of the special case-independent keywords CURRENT_TIME, CURRENT_DATE or CURRENT_TIMESTAMP.

```shell $ echo 'create table bar (baz text, created_at timestamp default CURRENT_TIMESTAMP)' | sqlite3 foo.db $ sqlite3 foo.db SQLite version 3.39.5 2022-10-14 20:58:05 Enter ".help" for usage hints. sqlite> .schema bar CREATE TABLE bar (baz text, created_at timestamp default CURRENT_TIMESTAMP); sqlite> .exit

Summary

Recently, I deployed an instance of datasette to Vercel with the following plugins:

• datasette-auth-tokens
• datasette-insert

With the above plugins, I was able to insert new data to local sqlite db. However, when it comes to the deployment on Vercel, things behave differently. I observed some errors from the logs console on Vercel:

console File "/var/task/datasette/database.py", line 179, in _execute_writes conn = self.connect(write=True) File "/var/task/datasette/database.py", line 93, in connect assert not (write and not self.is_mutable) AssertionError

I think it is a potential bug.

Reproduce

Hi! Wondering if this issue is limited to my local system or if it affects others as well.

It seems like 3.11 errors out on a "litestream-restored" database. On further investigation, it also appears to conk out on 3.10.8 but works on 3.10.7 and 3.10.6.

To demo issue I created a test database, replicated it to an aws s3 bucket, then restored the same under various .pyenv-versioned shells where I test whether I can read the database via the sqlite3 cli.

```sh

create new shell with 3.11.3

litestream restore -o data/db.sqlite s3://mytestbucketxx/db sqlite3 data/db.sqlite

SQLite version 3.41.2 2023-03-22 11:56:21

Enter ".help" for usage hints.

sqlite> .tables

_litestream_lock _litestream_seq movie

sqlite>

```

However this get me an OperationalError when reading via datasette:

In both scenarios, the only dependencies were the pinned python version and the latest Datasette version 0.64.

Does what it says and nothing else. This is the same set of paths as Datasette uses.

I deployed a fairly basic instance of Datasette (datasette-auth-passwords is the only plugin) using Heroku. The deployed URL now gives a "Deceptive site ahead" warning to users.

Is there way around this? Maybe a way to add ownership verification through Google's search console?

Many thanks for the sqlite-utils suite of utilities. Has made my life much much easier. I used this to create a table and enable FTS. All works fine. The datasette utility detects FTS and shows a text box. Searching for a term using that interface works well.

However, when I start to use features by following https://www.sqlite.org/fts5.html section "3. Full-text Query Syntax" I seem to run into issues that I suspect is due to escape_fts wrapper function.

As an example, if i search for the term "^குகை"on the text box in datasette it produces 140 results. However, when i tweak the query produced by datasette to not use "escape_fts" it produces 5 results.

Similarly, when I try to restrict the search to a single column in FTS using a spec like {title : ^குகை} it returns no rows. The same thing pulls results when used without escape_fts. The text in the table is in Tamil language and the search term is a Tamil word.

... where posts_fts match escape_fts(:search) vs

... where posts_fts match (:search)

Any ideas why? How can I get the benefits of both escaping as well as utilizing different facets of providing / controlling search terms? Thanks.

Related: - #2049 - #1709

I added a virtual column (no storage overhead) to the output that easily links back to the source. It works nicely out of the box with datasette:

I got bit a bit by https://github.com/simonw/sqlite-utils/issues/411, so I went with a manual table_xinfo and creating the table via execute. Happy to adjust if that issue moves, but this seems like it works.

I also added my best-guess instructions for local development on this package. I'm shooting in the dark, so feel free to replace with how you work on it locally.

Neat project! You can probably increase performance using my python interface to Notes, macnotesapp, which uses Scripting Bridge and bulk queries for much better performance than AppleScript.

Another related project is PyXA which uses Scripting Bridge to access Notes (and many other apps) and can return all the notes at once as opposed to calling AppleScript for each note.

macnotesapp allows you to access multiple accounts and folders as well.

```python from macnotesapp import NotesApp

NotesApp() provides interface to Notes.app

notesapp = NotesApp()

Get list of notes (Note objects for each note)

notes = notesapp.notes() note = notes[0] print( note.id, note.account, note.folder, note.name, note.body, note.plaintext, note.password_protected, )

print(note.asdict())

```

It's not currently obvious from the docs how you can ensure that Datasette runs well in situations where other processes may update the underlying SQLite files.

On the database that I have sent via linkedIn, datasette works great, but the following URL gives a 500 error.

http://127.0.0.1:8001/literature/authors_papers?authorId=100550354

The cause of the error is not apparent.

Is this expected behaviour?

Refs #417. Run it like this:

 datasette -d ~/Library

Uses a new plugin hook - available_databases()

When looping through databases in the index.html template, I'd like to print the description of each database alongside its name. But it appears that isn't passed in from the view, unless I'm missing it. It would be great to have that.

This modernizes some uses of double quotes for string literals to use only single quotes, fixes simonw/datasette#2001

While developing it, I manually enabled the stricter mode by using the code snippet at https://gist.github.com/cldellow/85bba507c314b127f85563869cd94820

I think that code snippet isn't generally safe/portable, so I haven't tried to automate it in the tests.

That's against this data https://data.sfgov.org/City-Management-and-Ethics/Supplier-Contracts/cqi5-hm2d imported using https://datasette.io/plugins/datasette-socrata

It's for Contract Type of Non-Purchasing Contract (Rents, etc.) - so possible that some of the spaces or punctuation in either the name of the value tripped up the code that decides if the X icon should be displayed.

Datasette currently uses the same table layout on the row pages as it does on the table pages:

https://datasette.io/content/pypi_packages?_sort=name&name__exact=datasette-column-inspect

https://datasette.io/content/pypi_packages/datasette-column-inspect

If you shrink down to mobile width you get this instead, on both of those pages:

I think that view, which I think of as the "card view", is plain better if you're looking at just a single row - and it (or a variant of it) should be the default presentation on the row page.

It's pretty common that i need to trim leading or trailing white space from lots of columns in a database a part of an initial ETL.

I use the following recipe a lot, and it would be great to include this functionality into sqlite-utils

trimify.sql sql select 'select group_concat(''update [' || name || '] set ['' || name || ''] = trim(['' || name || ''])'', ''; '') || ''; '' as sql_to_run from pragma_table_info('''||name||''');' from sqlite_schema;

then something like:

bash sqlite3 example.db < scripts/trimify.sql > table_trim.sql && \ sqlite3 $example.db < table_trim.sql > trim.sql && \ sqlite3 $example.db < trim.sql

Got this exception and had to make sure it always returned {}:

I'm not sold that this is a good idea, but thought it'd be worth writing up a ticket. Proposal: add a hook like

python def rewrite_sql(datasette, database, request, fn, sql, params)

It would be called from Database.execute, Database.execute_write, Database.execute_write_script, Database.execute_write_many before running the user's SQL. fn would indicate which method was being used, in case that's relevant for the SQL inspection -- for example execute only permits a single statement.

The hook could return a SQL statement to be executed instead, or an async function to be awaited on that returned the SQL to be executed.

Plugins that could be written with this hook:

• https://github.com/cldellow/datasette-ersatz-table-valued-functions would use this to avoid monkey-patching
• a plugin to inspect and reject unsafe Spatialite function calls (reported by Simon in Discord)
• a plugin to do more general rewrites of queries to enforce table or row-level security, for example, based on the currently logged in actor's ID
• a plugin to maintain audit tables when users write to a table
• a plugin to cache expensive queries (eg the queries that drive facets) - these could allow stale reads if previously cached, then refresh them in an offline queue

Flaws with this idea:

execute_fn and execute_write_fn would not go through this hook, which limits the guarantees you can make about it for security purposes.

There's one catch with batched inserts: if your CLI tool fails half way through you could end up with a partially populated table - since a bunch of batches will have succeeded first.

...

If people care about that kind of thing they could always push all of their inserts to a table called _tablename and then atomically rename that once they've uploaded all of the data (assuming I provide an atomic-rename-this-table mechanism).

The link in Play with a live demo in Getting started to https://fivethirtyeight.datasettes.com/fivethirtyeight is broken and the datasette is no longer working (maybe due to the end of the free tier).

In this issue I replaced a whole bunch of places that used the non-async app_client fixture with an async ds_client fixture instead: - #1959

But I didn't get everything, and a lot of tests are still using the old TestClient mechanism as a result.

The main work here is replacing all of the app_client_... fixtures which use variants on the default client - and changing the tests that call make_app_client() to do something else instead.

This requires some careful thought. I need to come up with a really nice pattern for creating variants on the ds_client default fixture - and do so in a way that minimizes the number of open files, refs:

Idea: a /-/permissions introspection endpoint for listing registered permissions

Originally posted by @simonw in https://github.com/simonw/datasette/issues/1939#issuecomment-1345691103

Consider this example: https://ripgrep.datasette.io/repos?sql=select+json_group_array%28full_name%29+from+repos

sql select json_group_array(full_name) from repos

My intention here was to get a string of JSON I can copy and paste elsewhere - see: https://til.simonwillison.net/sqlite/compare-before-after-json

The truncation isn't helping here.

It would be neat not to show write permissions against immutable databases too - and not hard from a performance perspective since it doesn't involve hundreds more permission checks.

That will need permissions to grow a flag for if they need a mutable database though, which is a bigger job.

Also, DO show the _memory database there if Datasette was started in --crossdb mode.

This will be the single biggest breaking change for the 1.0 release.

Datasette 1.0 will have a stable template context. I'm going to achieve this by refactoring the templates to work only with keys returned by the API (or some of its extras) - then the API documentation will double up as template documentation.

It's fixable by swiching away from ubuntu-latest according to:

• https://github.com/actions/setup-python/issues/355#issuecomment-1335042510

But https://endoflife.date/python says that 3.6 end of life was almost 6 years ago, and end of security support nearly 1 year ago.

So I'm OK dropping support entirely - Python 3.6 users will still be able to install version 3.30, just not any releases that come next.
