# Change Log All notable changes to this project will be documented in this file. This change log follows the conventions of [keepachangelog.com](http://keepachangelog.com/). ## [0.1.20] - Unreleased ## [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](https://github.com/Day8/re-frame-trace/issues/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](https://github.com/benedekfazekas/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](https://github.com/Day8/re-frame-trace/issues/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](https://github.com/Day8/re-frame-trace/issues/126) * Only allow one time based filter at a time [#125](https://github.com/Day8/re-frame-trace/issues/125) * Persist trace expansions when changing tab [#105](https://github.com/Day8/re-frame-trace/issues/105) * Hide :sub/create traces for cached subscriptions [#93](https://github.com/Day8/re-frame-trace/issues/93) * Persist filter category settings to localstorage [#121](https://github.com/Day8/re-frame-trace/issues/121) * Highlight events in trace window [#106](https://github.com/Day8/re-frame-trace/issues/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](https://github.com/Day8/re-frame-trace/pull/89) * External popout window. [#92](https://github.com/Day8/re-frame-trace/issues/92) * Namespace aware truncation in the traces panel. [#100](https://github.com/Day8/re-frame-trace/pull/100) * App DB expansions and contractions now persist across reloads. Note the [limitations](https://github.com/Day8/re-frame-trace/blob/master/docs/README.md#app-db-path-expansions) 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 ### Added * Log trace data to the console when clicking on it. ## [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 ## [0.1.1] - 2017-08-16 ### Added * Add event filtering * Pin the filter input to the top of the panel ### Changed * Improve installation instructions ### Fixed * Fix panel resizing ## [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](https://github.com/Day8/re-frame-trace/pull/14) via [Dexter Gramfors](https://github.com/Dexterminator). **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](https://github.com/Day8/re-frame-trace/pull/13) via [Dexter Gramfors](https://github.com/Dexterminator). ## [0.0.7] - 2017-04-13 This was a botched deploy. See 0.0.8. ## [0.0.6] - 2017-03-28 ### Added * Added getting started instructions to README.
