Based on:


This is a refactor of how App Router implements async navigations. In this context, an "async" navigation is one where the target route is not known at the time the navigation is initiated by the user.

App Router currently processes navigations and action sequentially, using async/await. However, it also overrides pending async navigations if a newer one occurs in the meantime. There are lots of escape hatches and special cases to handle this, but it's not modeled cleanly, and certain operations are still unnecessarily blocking.

Instead, I'm rewriting the reducer-based implementation to something more like a coroutine or generator function. This is an incremental rewrite so not everything will be converted all at once.

In this first PR, I introduce the concept of a "continuation navigation". This is a navigation action that occurs as a result of an earlier navigation attempt.

A continuation navigation only proceeds if the parent navigation hasn't been superseded by a newer navigation.

To track this, the App Router state has an incrementing counter called navigationId. Every new navigation increments this counter.

When a continuation navigation is processed, it compares the navigation ID of its parent (the one that spawned the continuation) with the current navigation ID. If they match, the continuation proceeds. If they do not match, it implies a newer navigation has superseded it.

The principle is that the most recent navigation initiated by the user always takes precedence.

The first reducer I've rewritten to use this new mechanism is the serverPatchReducer. In the pre-Segment Cache implementation, the serverPatchReducer was responsible for all dynamic data fetching; now with Segment Cache, it's only used in cases where the route returned during a navigation does not match the one that was prefetched.

In the new implementation, we use a continuation navigation to patch up the tree with missing data — but only if there hasn't been a newer navigation in the meantime. This removes a race condition in the old implementation.

(The serverPatchReducer mechanism is still being relied on by some of the other reducers that I have not yet rewritten, like restoreReducer. I will delete it once the remaining reducers are converted.)

Commit: 36d6f1b

This is a refactor of the ppr-navigations module to support navigating
to a new tree and refreshing shared layouts within the same navigation.

Rather than modeling navigations and refreshes/revalidations as
separate operations, a refresh is considered a special case of a
navigation where any existing dynamic data is disregarded, and new
data is fetched from the server. The rest of the tree is diffed as
usual, and the routing behavior is the same.

Previously, the ppr-navigations module would revert to the "create"
path whenever it was missing dynamic data (the CacheNode) for a
shared segment. Now, the FlightRouterState alone is used to diff
the old and new trees.

When dynamic data is missing, any shared segment (one that exists in
both the old and new trees) is considered to be part of a "refresh", and
any segment that is present only in the new tree is considered to be
part of a "navigation". There are subtle distinctions in behavior
between refreshes and navigations. For example, refreshed page segments
aren't scrolled to, but navigated page segments are.

Rewrite of the Server Action reducer to use the PPR/Segment Cache
navigation implementation, rather than the old lazy
fetch implementation.

Server Actions may trigger a revalidation, a redirect, or both. They
may also invalidate the cache. The behavior could be naively implemented
using router.refresh() and router.push(). Semantically, the routing
behavior is equivalent.

The main difference is that the server that invokes the action may
also send back new data for the page within the same response. Compared
to a separate request, this data is more likely to be consistent with
any data that may have been mutated by the action, due to global data
propagation races. (It's also faster since it avoids an extra
server waterfall.)

So, navigations initiated by a Server action must be able to "seed"
the navigation with the data it just received from the server. I've
added a new internal method, navigateToSeededRoute, that implements
this behavior.
The server form of refresh() is used to re-render all the dynamic
data on the current page. Unlike updateTag/revalidateTag, it does not
affect any cached data, so the client cache should not evict any of
its entries.

Internal refactor. When navigating to an unknown URL whose route is not
already in the  cache, we will have already received data from the
server _before_ we construct the next CacheNode tree. This is
essentially the same as  when a Server Action triggers a navigation and
sends back data in the same response. So, this updates the
implementation so both cases are handled the same way: by passing in
"seed" data into the function that constructs the next CacheNode tree.
Updates the NavigationTask type to represent the full tree, rather than
just the patch. Then we can reuse the logic in
convertServerPatchToFullTree to line up the server response with the
pending CacheNodes.

No behavioral changes, just cleans up the implementation by using the
new function added in the previous commit.

This is a refactor of how App Router implements async navigations.
In this context, an "async" navigation is one where the target route is
not known at the time the navigation is initiated by the user.

App Router currently processes navigations and action sequentially,
using async/await. However, it also overrides pending async navigations
if a newer one occurs in the meantime. There are lots of escape hatches
and special cases to handle this, but it's not modeled cleanly, and
certain operations are still unnecessarily blocking.

Instead, I'm rewriting the reducer-based implementation to something
more like a coroutine or generator function. This is an incremental
rewrite so not everything will be converted all at once.

In this first PR, I introduce the concept of a "continuation
navigation". This is a navigation action that occurs as a result of an
earlier navigation attempt.

A continuation navigation only proceeds if the parent navigation hasn't
been superseded by a newer navigation.

To track this, the App Router state has an incrementing counter called
`navigationId`. Every new navigation increments this counter.

When a continuation navigation is processed, it compares the navigation
ID of its parent (the one that spawned the continuation) with the
current navigation ID. If they match, the continuation proceeds. If
they do not match, it implies a newer navigation has superseded it.

The principle is that the most recent navigation initiated by the user
always take precedence.

The first reducer I've rewritten to use this new mechanism is the
serverPatchReducer. In the pre-Segment Cache implementation, the
serverPatchReducer was responsible for all dynamic data fetching; now
with Segment Cache, it's only used in cases where the route returned
during a navigation does not match the one that was prefetched.

In the new implementation, we use a continuation navigation to patch
up the tree with missing data — but only if there hasn't been a newer
navigation in the meantime. This removes a race condition in the
old implementation.

(The serverPatchReducer mechanism is still being relied on by some of
the other reducers that I have not yet rewritten, like restoreReducer.
I will delete it once the remainings reducers are converted.)
