gh-133439: Fix the error message in the sqlite3 CLI#133807

StanFromIreland · 2025-05-10T07:37:17Z

Use print for file consistency
Actually test for the full improved error message
Correct error message, messages do not have the '.'

Issue: sqlite3 CLI does not recognize dot commands with trailing spaces #133439

I don't think this PR is needed anymore, except maybe for the assertIn

StanFromIreland · 2025-05-10T08:06:44Z

Should the error message not be consistent with all other cpython error messages?

I think it is still better to use print for clarity (we don't have to look it up) and consistency, all other writing in the file is done so.

I think it is still better to use print for clarity (we don't have to look it up) and consistency, all other writing in the file is done so.

I guess so. I actually expected InteractiveConsole to have a write_stderr and a write_stdout but there's none, so maybe only using print makes sense. WDYT @erlend-aasland?

While working on something else I realized the current error message is error-ed even more:

sqlite> .HELP Error: unknowncommand or invalid arguments: "HELP".

Friendly ping @erlend-aasland

erlend-aasland · 2025-06-13T16:49:38Z

Stan, did you want to include further amendments in this PR?

StanFromIreland · 2025-06-13T17:04:46Z

I don't mind, I can include it here. All that is to be done for the . help is to just use .rstrip instead of .strip.

This reverts commit 97d002d.

Lib/sqlite3/__main__.py

 t = theme.traceback
- self.write(f'{t.type}Error{t.reset}:{t.message} unknown'
- f'command or invalid arguments: "{unknown}".\n{t.reset}')
+ print(f'{t.type}Error{t.reset}:{t.message} unknown command '


Note that the banner and tracebacks are written using self.write(). Why not use it here for consistence?

Errors (35) use print? And so do the other match statements branches.

Other branches output to stdout.
Line 35 perhaps should use self.write() too.

We can leave execute() for now. It is not worth to rewrite it just for this.

Suggested change
print(f'{t.type}Error{t.reset}:{t.message} unknown command '
self.write(f'{t.type}Error{t.reset}:{t.message} unknown command '
It is up to you/Erlend. The box to allow you to commit was checked.

Thanks @StanFromIreland for the PR, and @encukou for merging it 🌮🎉.. I'm working now to backport this PR to: 3.14.
🐍🍒⛏🤖

miss-islington-app · 2025-06-19T11:46:40Z

Sorry, @StanFromIreland and @encukou, I could not cleanly backport this to 3.14 due to a conflict.
Please backport using cherry_picker on command line.

StanFromIreland · 2025-06-19T12:28:10Z

The original was "backported" to 3.13 but it seems it was modified:

cpython/Lib/sqlite3/__main__.py

Lines 64 to 65 in 55a34a1

self.write("Error: unknown command or invalid arguments:"
f' "{unknown}".\n') 

@encukou Should we backport this (to 3.13) too so they are the same?

bedevere-app · 2025-06-19T12:32:31Z

GH-135708 is a backport of this pull request to the 3.14 branch.

encukou · 2025-06-19T12:57:22Z

Now that I look at the diff, I don't see a bug to fix in 3.14.

StanFromIreland · 2025-06-19T13:06:46Z

There is no bug because the author modified the backport, the message is different though.
