Add HistoryPanel to capture ajax requests. #1250

tim-schilling · 2020-03-20T23:24:23Z

This creates a new panel, HistoryPanel which makes use of the
Toolbar.store to support a history of the toolbar as requests are
made.

The interface changes as follows:
Panel.is_historical - Indicates that the panel's button and content
should be updated when switching between snapshots of the history.

Toolbar.store - Will no longer generate a new store_id when the
instance already has a value.

DEBUG_TOOLBAR_CONFIG.HISTORY_POST_TRUNC_LENGTH - Allows the request's
POST content to be truncated in the history panel's content.

LoggingPanel and StaticFilesPanel now utilize the get_stats method
to fetch panel data for nav_subtitle.

The core concepts were derived from that package.

Closes #1066, #1032, #998.

If we think this is going to be merged, we'll need to do a major version bump. But before we do that, I'll want to go through the third party panels identified in the docs to at least identify if any will break.

matthiask · 2020-05-10T19:04:11Z

@tim-schilling Compatibility problems only really surface after a release, unfortunately. I think it would be alright to merge this and go ahead with it, maybe with an alpha/beta release (similar to 2.0a1) so that it is installable using pip --pre.

But I certainly wouldn't want to push this without your approval or if there is anything you'd still like to check before.

tim-schilling · 2020-05-21T02:03:13Z

I have not forgotten about this, I've been busy with paid work and haven't had time for FOSS development. I will get back around to this though.

@matthiask This requires another review due to me making a few changes:

Rebasing on the new main branch.
Displaying the request variables as a table similar to the cache panel rather than a JSON strong.
Supporting a refresh button within the history panel. This allows the user to load up the debug toolbar info for requests that have been performed since the original request
Increased RESULTS_CACHE_SIZE to 25 (from 10). The reason for this is because the original request's data was being dropped before I opened the toolbar during my testing. With ajax-y applications, I feel like this new setting better reflects the number of ajax requests between full requests.

This looks very good already, thank you!

Typo? (VersionsPanel)

Yeah, copy paste error. Thanks for catching it.

I was hoping there would be a way to use https://docs.djangoproject.com/en/3.1/ref/settings/#default-exception-reporter-filter for this. I didn't even know there was a setting for this, I assumed it was internal-only. I'd have referenced the setting earlier if I was aware that it existed at all.

(Also, maybe Django should use the SafeExceptionReporterFilter instead of reimplementing parts of it in django.contrib.auth.)

Ah, good call. I'll rework this to make use of that.

I'm thinking I need to remove this. The django implementation only uses it for debug cases which defeats the purpose of this.

tim-schilling · 2020-08-24T19:44:09Z

@matthiask I'm curious about your v3.0 release plan. Would this be included or would it be smarter to do a 3.0 and then a 3.1.0a immediately after? I can make a post on forum.djangoproject.com asking for alpha testers.

matthiask · 2020-08-27T15:44:41Z

@tim-schilling I think it might be worth it to do another alpha. Generally I don't worry too much about stability since mostly people aren't supposed to use django-debug-toolbar in production :-)

It's enough work to create a release already, and I'd rather speed the release process up a bit.

tim-schilling · 2020-08-28T13:40:44Z

Sounds good. Let me know where I can help out.

matthiask · 2020-09-05T12:00:22Z

@tim-schilling I have just pushed 3.0a3 now, if you want to add a post in the forum that would be awesome. Thanks!

tim-schilling · 2020-09-08T12:56:23Z

@matthiask Thanks for the update! I'll do that this morning.

matthiask · 2020-09-08T12:57:50Z

@tim-schilling It may be worth it uploading another release; I fixed a crash which happened when using request as a file-like object (see 3.0a3...master). What do you think? Maybe it's an edge case....

tim-schilling · 2020-09-08T13:11:37Z

No, I doubt it's an edge-case if it was found that quickly. I agree it's worth to bump the version since it was caught and fixed.

matthiask · 2020-09-08T13:21:11Z

Alright, https://pypi.org/project/django-debug-toolbar/3.0a4/ is available on PyPI.
