Merges non intersecting sorted lists of pointers The lists of pointers are non intersecting if for every pair the next condition is met MaxElement(l1) < MinElement(l2) or MaxElement(l2) < MinElement(l1)

This method is used to propagate PayloadMode restrictions in call tree path down to logical root. If some method in call tree path has PayloadMode OwnPlusSystem, this mode can be shifted to the logical root. This allows to keep simple nodes in the middle of call tree path, and display warning label "Some children are excluded" considering only logical root node

Note: the function is applicable to dal CallTreePath We have to make CallTreePath generic and have raw version in dal and merged version in features but its quite a big refactoring so we decided to postpone it till we have at least one more such hack

Note: To deserialize this class you have to specify instance of in JsonSerializerSettings

Wrapper type user as a type alias with reduced number of type parameters

Null value means undefined systemness. Introduced for aggregated nodes.

When we are converting a snapshot file and encounter some warnings - we are showing a viewmodel with some text but not holding snapshot files anymore. This gives an opportunity to remove the snapshot before pressing "Show snapshot" button We are using snapshot converter lifetime and assume nobody will try to delete the snapshot that we are processing.

If null is passed items will not be containing highlighted rich text parts (used for Rider)

NOTE(Korovin): Possible optimizations: inline the accessing Func`1 in the CompactTreeReader.

Fix for DTRC-27501 The first GC Thread interval contains "Thread doesn't exist" region

Helper for small on-off layers, which will call write delegate for every event

Previously we were creating a layer with an event for each context switch that contained a number of currently running threads. This caused long processing, big memory consumption and long writing times of such layer for big snapshots. But we don't need such accuracy to show static non-resizable CPU chart. I've averaged the numbers on a "pixel" width range so that we would see more or less the same chart but will write and store only `pixels` number of events.

Processes the snapshot

This parameter is passed as a reference because we sometimes want to observe the values even if the processing threw an exception. Used for statistics.

Thread lifetime events within [session.Start; session.Stop] interval for profiled process

Copy paste of the JetBrains.Threading.TaskEx.Select[TSrc, TDst] but without `.ConfigureAwait(false)`

It returns normalized state

It returns default state

See PerformanceSnapshotViewer.CheckSnapshotStatus

This is the lifetime of the "Snapshot scope" which is terminated last, after all other activities already finished

Keep memory traffic at minimum. Hot path function.

Shows "File save dialog" for currently opened in the viewer snapshot and saves it in the chosen place.

Returns true if snapshot is successfully saved. False if user rejected to save the snapshot or canceled the saving process.

Returns true if snapshot is successfully saved. False if user rejected to save the snapshot or canceled the saving process.

When we are opening a snapshot file indirectly(through unpacking) we want to "protect" original input file from modifications by the outer world. Here we use snapshot component's lifetime for this, keeping in mind that all destructive actions with the snapshot files can happen in the outer SnapshotScopeLifetime.

This class is used to share Visible and Total ranges between viewports in VS. First one is used to summary and second for threads toolwindows.

The interface is exposed to the features layer So it contains merged FunctionUID (FunctionUIDm) Those values cannot be directly stored using snapshot settings accessor and must be converted using IFuidsMatcher before saving

The interface is similar to But it has raw FunctionUID (FunctionUID) Those values cannot be directly used in features layer and must be converted using IFuidsMatcher

Diagnostics fields, don't have to be exact, we will check ratio of recreations/moves to detect problems.

Class used as alias to shorten template syntax for EnumerationListener

Next tick defines the longest interval from current tick, where all of the following conditions are true:
1. Filter acceptance is not changed (AcceptsCurrentRange is constant)
2. Listener activity is not changed (ListensToCurrentRange is constant)
3. If filter has own payload, then CurrentRangePayloadDensity is constant

Convention for callee: (tick <= NextTick).
Conventions for implementor (before call ===> after call):
(tick < NextTick) ===> NextTick doesn't change.
(tick == NextTick) ===> (NextTick > tick)
(tick > NextTick) ===> Exception

Conventions for implementor:
(tick < NextTick) ===> NextTick doesn't change.
(tick == NextTick) ===> (NextTick > tick)

List of all filter history management objects. First one is Undo history, second - Redo history and all subsequent items - individual filter histories.

If null is passed - default defer update time is set, which is 1 second
