AbstractRange.cpp 22493
AbstractRange.h Called when the process is shutting down. 8172
AncestorIterator.h Implementation of some generic iterators over ancestor nodes. Note that these keep raw pointers to the nodes they iterate from, and as such the DOM should not be mutated while they're in use. There are debug assertions (via nsMutationGuard) that check this in debug builds. 4903

BindContext.cpp 1394
BindContext.h State that is passed down to BindToTree. 3593
BodyConsumer.cpp Called on successfully reading the complete stream. 24822
BodyConsumer.h Returns a promise which will be resolved when the body is completely consumed and converted to the wanted type (See ConsumeType). @param aGlobal the global to construct the Promise. @param aMainThreadEventTarget the main-thread event target. The reading needs to start on the main-thread because of nsIInputStreamPump. @param aBodyStream the stream to read. @param aSignalImpl an AbortSignal object. Optional. @param aType the consume type. @param aBodyBlobURISpec this is used only if the consume type is ConsumeType::Blob. Optional. @param aBodyLocalPath local path in case the blob is created from a local file. Used only by ConsumeType::Blob. Optional. @param aBodyMimeType the mime-type for blob. Used only by ConsumeType::Blob. Optional. @param aMixedCaseMimeType is needed to get mixed case multipart boundary value to FormDataParser. @param aBlobStorageType Blobs can be saved in temporary file. This is the type of blob storage to use. Used only by ConsumeType::Blob. @param aRv An ErrorResult. 5184
BodyUtil.cpp A simple multipart/form-data parser as defined in RFC 2388 and RFC 2046. This does not respect any encoding specified per entry, using UTF-8 throughout. This is as the Fetch spec states in the consume body algorithm. Borrows some things from Necko's nsMultiMixedConv, but is simpler since unlike Necko we do not have to deal with receiving incomplete chunks of data. This parser will fail the entire parse on any invalid entry, so it will never return a partially filled FormData. The content-disposition header is used to figure out the name and filename entries. The inclusion of the filename parameter decides if the entry is inserted into the FormData as a string or a File. File blobs are copies of the underlying data string since we cannot adopt char* chunks embedded within the larger body without significant effort. FIXME(nsm): Bug 1127552 - We should add telemetry to calls to formData() and friends to figure out if Fetch ends up copying big blobs to see if this is worth optimizing. 15389
BodyUtil.h Creates an array buffer from an array, assigning the result to |aValue|. The array buffer takes ownership of |aInput|, which must be allocated by |malloc|. 3001
BorrowedAttrInfo.cpp 772
BorrowedAttrInfo.h Struct that stores info on an attribute. The name and value must either both be null or both be non-null. Note that, just as the pointers returned by GetAttrNameAt, the pointers that this struct hold are only valid until the element or its attributes are mutated (directly or via script). 1168

ChildIterator.cpp 8483
ChildIterator.h AllChildrenIterator traverses the children of an element including before / after content and shadow DOM. The iterator can be initialized to start at the end by providing false for aStartAtBeginning in order to start iterating in reverse from the last child. Note: it assumes that no mutation of the DOM or frame tree takes place during iteration, and will break horribly if that is not true. 7166

DirectionalityUtils.cpp This file contains most of the code to implement html directionality. This includes default direction, inheritance, and auto directionality. A useful perspective is separating the static and dynamic case. In the static case, directionality is computed based on the current DOM, closely following the specification, e.g. in ComputeAutoDirectionality. Dynamic changes, e.g. OnSetDirAttr, are propagated to the impacted nodes, for which the static case is re-run. To minimize searching for dir=auto nodes impacted by a dynamic change, several flags are maintained (see their declaration for documentation): - NodeAncestorHasDirAuto and NodeAffectsDirAutoSlot apply to all nodes. They are set when a node is placed somewhere in the tree and set or cleared when a dir attribute changes. - NS_MAY_SET_DIR_AUTO applies to text. It is set whenever a text node might be responsible for the auto directionality of a dir=auto element. It is cleared when the element is unbound. 32542
DirectionalityUtils.h Various methods for returning the directionality of a string using the first-strong algorithm defined in http://unicode.org/reports/tr9/#P2 @param[out] aFirstStrong the offset to the first character in the string with strong directionality, or UINT32_MAX if there is none (in which case the return value is Directionality::Unset). @return the directionality of the string, or Unset if not available. 6417

DOMMozPromiseRequestHolder.h This is a helper class that can be used when MozPromises are being consumed by binding layer code. It effectively creates a MozPromiseRequestHolder that auto-disconnects when the binding's global is disconnected. It can be used like this: RefPtr<Promise> SomeAsyncAPI(Args& aArgs, ErrorResult& aRv) { nsIGlobalObject* global = GetParentObject(); if (!global) { aRv.Throw(NS_ERROR_DOM_INVALID_STATE_ERR); return nullptr; } RefPtr<Promise> outer = Promise::Create(global, aRv); if (aRv.Failed()) { return nullptr; } RefPtr<DOMMozPromiseRequestHolder> holder = new DOMMozPromiseRequestHolder(global); DoAsyncStuff()->Then( global->EventTargetFor(TaskCategory::Other), __func__, [holder, outer] (const Result& aResult) { holder->Complete(); // Note, you can access the holder's bound global in // your reaction handler. Its mostly likely set if // the handler fires, but you still must check for // its existence since something could disconnect // the global between when the MozPromise reaction // runnable is queued and when it actually runs. nsIGlobalObject* global = holder->GetParentObject(); NS_ENSURE_TRUE_VOID(global); outer->MaybeResolve(aResult); }, [holder, outer] (nsresult aRv) { holder->Complete(); outer->MaybeReject(aRv); })->Track(*holder); return outer.forget(); } NOTE: Currently this helper class extends DETH. This is only so that it can bind to the global and receive the DisconnectFromOwner() method call. In this future the binding code should be factored out so DETH is not needed here.

FragmentDirective.h @brief The `FragmentDirective` class is the C++ representation of the `Document.fragmentDirective` webidl property. This class also serves as the main interface to interact with the fragment directive from the C++ side. It allows to find text fragment ranges from a given list of `TextDirective`s using `FragmentDirective::FindTextFragmentsInDocument()`. To avoid Text Directives being applied multiple times, this class implements the `uninvoked directive` mechanism, which in the spec is defined to be part of the `Document` [0].

HighlightRegistry.h @brief HighlightRegistry manages all `Highlight`s available to a `Document`. This class is exposed via `HighlightRegistry.webidl` and used to add or remove `Highlight` instances to a document and binding it to a highlight name. The HighlightRegistry idl interface defines this class to be a `maplike`. To be able to access the members of the maplike without proper support for iteration from C++, the insertion and deletion operations are overridden and the data is also held inside of this class. @see https://drafts.csswg.org/css-highlight-api-1/#registration 5176

IDTracker.cpp 9549
IDTracker.h Class to track what element is referenced by a given ID. To use it, call one of the Reset methods to set it up to watch a given ID. Call get() anytime to determine the referenced element (which may be null if the element isn't found). When the element changes, ElementChanged will be called, so subclass this class if you want to receive that notification. ElementChanged runs at safe-for-script time, i.e. outside of the content update. Call Unlink() if you want to stop watching for changes (get() will then return null). By default this is a single-shot tracker --- i.e., when ElementChanged fires, we will automatically stop tracking. get() will continue to return the changed-to element. Override IsPersistent to return true if you want to keep tracking after the first change. 6846

This is useful because constructing an nsAttrValue from an nsAString can be expensive when the buffer of the string is not shared. This treats nsAttrValueOrString(nullptr) as the empty string, to help with contexts where a null pointer denotes an empty value. Since a raw pointer to the passed-in string is kept, this class should only be used on the stack. 2772

nsIImageLoadingContent.idl This interface represents a content node that loads images. The interface exists to allow getting information on the images that the content node loads and to allow registration of observers for the image loads. Implementors of this interface should handle all the mechanics of actually loading an image -- getting the URI, checking with content policies and the security manager to see whether loading the URI is allowed, performing the load, firing any DOM events as needed. An implementation of this interface may support the concepts of a "current" image and a "pending" image. If it does, a request to change the currently loaded image will start a "pending" request which will become current only when the image is loaded. It is the responsibility of observers to check which request they are getting notifications for. Please make sure to update the MozImageLoadingContent WebIDL mixin to mirror this interface when changing it. 6104

nsIScriptChannel.idl An interface representing a channel which will have to execute some sort of program provided via its URI to compute the data it should return. If a channel implements this interface, the execution of the program in question will be restricted in the following ways: - If the channel does not have an owner principal, the program will not be executed at all, no matter what. This is necessary because in this circumstance we have no way to tell whether script execution is allowed at all for the originating security context of this channel. - If the channel has an owner principal, how it is executed is controlled by this interface. However if the owner principal does not subsume the principal of the environment in which the program is to be executed the execution will be forced to happen in a sandbox. 2847

nsWindowMemoryReporter.cpp Don't trigger a ghost window check when a DOM window is detached if we've run it this recently. 36091
nsWindowMemoryReporter.h nsWindowMemoryReporter is responsible for the 'explicit/window-objects' memory reporter. We classify DOM window objects into one of three categories: - "active" windows, which are displayed in a tab (as the top-level window or an iframe), - "cached" windows, which are in the fastback cache (aka the bfcache), and - "detached" windows, which have a null docshell. A window becomes detached when its <iframe> or tab containing the window is destroyed -- i.e., when the window is no longer active or cached. Additionally, we classify a subset of detached windows as "ghost" windows. Although ghost windows can happen legitimately (a page can hold a reference to a cross-domain window and then close its container), the presence of ghost windows is often indicative of a memory leak. A window is a ghost if it meets the following three criteria: 1) The window is detached. 2) There exist no non-detached windows with the same base domain as the window's principal. (For example, the base domain of "wiki.mozilla.co.uk" is "mozilla.co.uk".) This criterion makes us less likely to flag a legitimately held-alive detached window as a ghost. 3) The window has met criteria (1) and (2) above for at least memory.ghost_window_timeout_seconds. This criterion is in place so we don't immediately declare a window a ghost before the GC/CC has had a chance to run. nsWindowMemoryReporter observes window detachment and uses mDetachedWindows to remember when a window first met criteria (1) and (2). When we generate a memory report, we use this accounting to determine which windows are ghosts. We use the following memory reporter path for active and cached windows: explicit/window-objects/top(<top-outer-uri>, id=<top-outer-id>)/ <category>/window(<window-uri>)/... For detached and ghost windows, we use explicit/window-objects/top(none)/<category>/window(<window-uri>)/... Where - <category> is "active", "cached", "detached", or "ghost", as described above. - <top-outer-id> is the window id of the top outer window (i.e. the tab, or the top level chrome window). Exposing this ensures that each tab gets its own sub-tree, even if multiple tabs are showing the same URI. - <top-uri> is the URI of the top window. Excepting special windows (such as browser.xhtml or hiddenWindowMac.xhtml) it's what the address bar shows for the tab. 6181

nsWrapperCache.cpp static 4888
nsWrapperCache.h Class to store the wrapper for an object. This can only be used with objects that only have one non-security wrapper at a time (for an XPCWrappedNative this is usually ensured by setting an explicit parent in the PreCreate hook for the class). An instance of nsWrapperCache can be gotten from an object that implements a wrapper cache by calling QueryInterface on it. Note that this breaks XPCOM rules a bit (this object doesn't derive from nsISupports). The cache can store objects other than wrappers. We allow wrappers to use a separate JSObject to store their state (mostly expandos). If the wrapper is collected and we want to preserve this state we actually store the state object in the cache. The cache can store 3 types of objects: a DOM binding object (regular JS object or proxy), an nsOuterWindowProxy or an XPCWrappedNative wrapper. The finalizer for the wrapper clears the cache. A compacting GC can move the wrapper object. Pointers to moved objects are usually found and updated by tracing the heap, however non-preserved wrappers are weak references and are not traced, so another approach is necessary. Instead a class hook (objectMovedOp) is provided that is called when an object is moved and is responsible for ensuring pointers are updated. It does this by calling UpdateWrapper() on the wrapper cache. SetWrapper() asserts that the hook is implemented for any wrapper set. A number of the methods are implemented in nsWrapperCacheInlines.h because we have to include some JS headers that don't play nicely with the rest of the codebase. Include nsWrapperCacheInlines.h if you need to call those methods. 30517

RadioGroupContainer.cpp A struct that holds all the information about a radio group. 7527
RadioGroupContainer.h 2106
RangeBoundary.h There are two ways of ensuring that `mRef` points to the correct node. In most cases, the `RangeBoundary` is used by an object that is a `MutationObserver` (i.e. `nsRange`) and replaces its `RangeBoundary` objects when its parent chain changes. However, there are Ranges which are not `MutationObserver`s (i.e. `StaticRange`). `mRef` may become invalid when a DOM mutation happens. Therefore, it needs to be recomputed using `mOffset` before it is being accessed. Because recomputing / validating of `mRef` could be an expensive operation, it should be ensured that `Ref()` is called as few times as possible, i.e. only once per method of `RangeBoundaryBase`. Furthermore, there are special implications when the `RangeBoundary` is not used by an `MutationObserver`: After a DOM mutation, the Boundary may point to something that is not valid anymore, i.e. the `mOffset` is larger than `Container()->Length()`. In this case, `Ref()` and `Get*ChildAtOffset()` return `nullptr` as an indication that this RangeBoundary is not valid anymore. Also, `IsSetAndValid()` returns false. However, `IsSet()` will still return true. 17686

ResizeObserver.cpp Returns the length of the parent-traversal path (in terms of the number of nodes) to an unparented/root node from aNode. An unparented/root node is considered to have a depth of 1, its children have a depth of 2, etc. aNode is expected to be non-null. Note: The shadow root is not part of the calculation because the caller, ResizeObserver, doesn't observe the shadow root, and only needs relative depths among all the observed targets. In other words, we calculate the depth of the flattened tree. However, these is a spec issue about how to handle shadow DOM case. We may need to update this function later: https://github.com/w3c/csswg-drafts/issues/3840 https://drafts.csswg.org/resize-observer/#calculate-depth-for-node-h 19256

This is okay, because for partially selected nodes no expensive node traversal is necessary. This cache is designed to be used in a context where no script is allowed to run. It assumes that the selection itself, or any range therein, does not change during its lifetime. By design, this class can only be instantiated in the `PresShell`. 50441
