[0.1.21] - Unreleased

Fixed

• Avoid throwing an error No item 0 in vector of length 0 under certain circumstances.

[0.1.20] - 2018-02-14

Upgrade notes

To take advantage of the more granular timing info in this version, you will need to upgrade to re-frame 0.10.5.

Added

• A time-travelling debugger. Navigating forwards and backwards through the event history updates app-db to match. Be careful when using this with a stateful backend; as in the movies if you change too much or go too far back, the future can become unpredictable.

Improved

• Improve Timing panel to show more granular timing info.

Fixed

• Settings panel has a scroll bar if your screen height is too small.

[0.1.19] - 2018-02-09

Changed

• Massive overhaul to how subscriptions are processed.
  • Subscriptions that exist but weren't run, now show up in the subscription panel.
  • Subscription creations and disposals that happen during figwheel reloads or otherwise outside of the re-frame event domino cycle are now correctly handled. If any of these happen, they show up in the new section Inter-Epoch Subscriptions.
  • All of the actions that happen to a subscription within an epoch are now shown. This lets you spot unusual behaviour like a subscription being created but not-run, or a subscription running multiple times.
  • Present better explanation messages when viewing the diff section for a sub where the value is unchanged, not run yet, or only run once.

Fixed

• Garden source dependencies are now working if you don't have your own dependency on Garden.
• New app-db path inspectors default to """ instead of "[]" so you can see the help text.

[0.1.18] - 2018-01-31

Fixed

• Garden source dependencies now work if you don't have your own dependency on Garden.

[0.1.17] - 2018-01-31

This version requires re-frame 0.10.4 to make use of the newly added Event panel.

Added

• New event panel. This panel shows the coeffects given to your event handler, the effects your event handler produced, and all of the interceptors in the chain.
• Debugging instructions if re-frame-trace fails to start.
• Setting to drop low level traces. This reduces the memory overhead of re-frame-trace as we can drop more traces that you are unlikely to want most of the time.
• Diff the previous value of a subscription with its current value.

Changed

• In the subs panel "Ignore n layer 2 subs" is now "Ignore n unchanged layer 2 subs". This is a more useful filter, as you can filter out noisy layer 2 subscriptions, while still seeing the changes that do happen to layer 2 subs.
• The version of Garden that re-frame-trace uses is now bundled as a source dependency so you should no longer get conflicts if you use Garden 2.
• Refactored re-frame-trace trace parsing internals to incrementally parse new traces.
• Clicking on a trace's expanded information now prints the entire trace to the console instead of just the tags.
• Improved efficency of rendering views that do not need to filter out view namespaces.
• app-db and subs panel now have a slightly more responsive design.

Fixed

• External windows not loading
• All app-db and subscription path expansions are now independent of each other #134.
• Layer 2/3 calculations are more accurate now. We now use the last seen layer level when a subscription runs, to inform it's layer level if it was created or destroyed.
• View namespaces that are ignored are no longer shown when showing traces for all epochs.
• Distinguish between subscriptions that return nil values and those that haven't run yet.
• Timing panel not showing elapsed event processing time.

[0.1.16] - 2018-01-26

There is now a React 16 variant of re-frame-trace available under the version 0.1.16-react16. If your application uses React 16 and Reagent 0.8.0-alpha2 or higher, this is the version that you will need to use.

Added

• Setting to control how many epochs are retained
• Setting to reset all epochs
• Setting to ignore epochs
• Setting to filter out trace for views from uninteresting namespaces

Changed

• Updated bundled re-frame version to 0.10.3, and bundled reagent version to 0.7.0. This shouldn't impact your project's dependencies as they are source bundled via mranderson.
• Add hyperlinks to docs

Fixed

• Set a print limit of 400 characters in the event header, to prevent very large events from DOSing the host application.
• XML encode # character in SVGs, fixing #130.
• Fix the reset tracing button in the traces panel.
• Fix a bug when there is only one traced event, re-frame-trace would allow you to go back an epoch, throwing an exception.

[0.1.15] - 2018-01-24

Added

• The app-db panel now has buttons to reset app-db to the state at the beginning or end of any epoch.
• The subscription panel shows subscriptions that were created and destroyed.
• The trace panel automatically filters traces to just the current epoch
• A new timing panel shows basic timing statistics around event processing and rendering. More to come here.

Changed

• re-frame-trace is now organised around epochs. An epoch includes an event being processed, subscriptions running in response, and the view re-rendering.
• A new visual design language.

Fixed

Lots of quality of life fixes:

• Lower count of items in sequence before expanding icon shows #126
• Only allow one time based filter at a time #125
• Persist trace expansions when changing tab #105
• Hide :sub/create traces for cached subscriptions #93
• Persist filter category settings to localstorage #121
• Highlight events in trace window #106

[0.1.14] - 2017-12-19

Added

• New state snapshotting feature: Click the camera to snapshot app-db, and click the load button to restore to your snapshot. Snapshots only persist for the browser session, they aren't available after reloading the browser.
• X button to remove app-db paths

Changed

• Switched from LESS to Garden styles. Now interactive development and debugging of re-frame-trace is even faster.
• Reopen/reattach external popup windows when reloading host application
• Reorganise namespace layout and remove (hidden) subviz panel and D3 dependency. This may return in the future though.
• Only sort subscriptions by the subscription key, not the whole vector
• Visual tweaks

Fixed

• Set panel width correctly so you can see the whole panel at all times. Previously the right edge was just off screen.

[0.1.13] - 2017-11-23

N.B. To make the best use of the new subscriptions panel, you also need to update to re-frame v0.10.3-alpha1.

Added

• Bright yellow text when re-frame trace is preloaded, but tracing is not enabled.
• Add preliminary subscriptions panel. Still a bit buggy and not very pretty, but it should be useful even in this state.

[0.1.12] - 2017-11-16

Added

• Preliminary support for React 16 component paths. #89
• External popout window. #92
• Namespace aware truncation in the traces panel. #100
• App DB expansions and contractions now persist across reloads. Note the limitations with this feature.

Changed

• Hide index spans (the blocks next to each element counting the number of elements in a collection)

[0.1.11] - 2017-10-27

Changed

• Rename app-state panel to app-db
• Visual improvements to data viewer

[0.1.10] - 2017-10-27

Removed

• Subvis panel has been commented out while it is in a broken state.

[0.1.9] - 2017-10-27

Added

• Limit captured traces to a maximum of 4,000 to prevent performance slowdowns.

Changed

• Speed up animations for autoscrolling to bottom of list
• Print full keyword for operation name

Fixed

• Bad merge for handling window width changing.

[0.1.8] - 2017-10-25

Added

• Add a new App State panel. This lets you visualise your application state and inspect it. You can add multiple selections to view a subset of your application state.

Fixed

• Handle window viewport size changing and other dragging bugs. This should be the last of them, but open an issue if you still find glitches when resizing.

[0.1.7] - 2017-09-25

Changed

• Improve style resetting
• Visual improvements

Fixed

• Fix panel resizing behaviour under edge cases

[0.1.6] - 2017-09-05

[0.1.5] - 2017-08-31

Changed

• Put CSS in resources directory

[0.1.4] - 2017-08-31

Added

• Save settings to localstorage to persist across reloads
• Autoscroll to the bottom of the traces panel when at the bottom
• Use LESS for CSS

[0.1.3] - 2017-08-24

Added

• Show/hide traces

[0.1.2] - 2017-08-16

Changed

• Move styles and components to trace folder

[0.1.0] - 2017-05-02

Changed

• Artifact coordinates changed from day8.re-frame/abra to day8.re-frame/trace.

[0.0.9] - 2017-05-02

Changed

• The preloads namespace now adds the tracing panel to the DOM automatically, so you don't need to change any of your app code to bring it in. #14 via Dexter Gramfors. Migration steps: Remove any explicit rendering instructions for day8.re-frame.trace/devtools in your app, as this is automatically added now.

[0.0.8] - 2017-04-13

Added

• There is now a preload namespace you can use to configure re-frame-trace. Install details are in the README.md. #13 via Dexter Gramfors.

[0.0.7] - 2017-04-13

This was a botched deploy. See 0.0.8.

[0.0.6] - 2017-03-28
