Web: reload the strategy that is open, not a share link left behind - #548
A signed-in person on the web build who opened a view link, clicked home, opened their own strategy and reloaded was left on the grey loading screen. It never filled in and the home button did nothing; the only way out was editing the address. The live beta (5.1.3) does the same. Nothing was lost.
Cause
Two things remember what a reload should reopen, and after those steps they named different strategies:
the address still read /share/ICR-…, and the tab still held the share code, so the reload opened the link again
the tab's store named the reader's own strategy, so the reload restored that too
Two editors opened, one over the other. Both loaded into the same open-strategy state, one lost, and its failure popped the top editor instead of itself. What was left was an editor whose strategy never became the open one: a loading screen, which takes no clicks.
Fix
The address follows what is open. The recorder that stores the open cloud strategy for a reload (openCloudStrategyRecorderProvider) now also tells the share link whether it is what a reload reopens: no while the reader's own strategy is open (the /share/… path leaves the address and the stored code is cleared), yes again when the strategy they read through the link is back on screen (both return). The link stays held in memory, so going back to that strategy in the same tab still reads through it. A reload now has one answer. A link that has not opened yet (it arrived offline) is left alone: a reload is its retry.
A load that cannot finish ends somewhere usable.
An editor whose strategy failed to open takes itself off the stack. It used to pop whatever was on top.
The loading screen has the real home button, live from the first frame. The rest of the skeleton still takes no clicks.
A load that lost to another strategy opening leaves without the "Could not load strategy" toast, since nothing the reader asked for failed.
Leaving through that home button drops the load, and so does opening another strategy before the first has finished. Before, the late answer opened the first one with no editor showing, or on top of the one opened after it.
One rule for a superseded open. Review kept finding one more wait after which an open the reader had left carried on (marking itself open, marking another strategy saved, pointing the upload queue at itself), so the last commit replaces the hand-written checks with one mechanism. An open carries an attempt (OpenAttempt, lib/strategy/open_attempt.dart) and waits only through opening.wait(...). A wait that returns after the open was closed or replaced throws there, and the one place that started the attempt (StrategyProvider._open) catches it, so nothing after any wait runs for a superseded open. The address follows the open strategy, so it is covered through it.
The waits, all through the helper:
Where
Waits
loadFromHive (local)
deleting unused pictures, writing a migrated strategy, making the storage folder, the page step
openCloudStrategy
the first cloud read, making the storage folder (desktop), the page step
initializeForStrategy (the page step, given the same attempt)
listing pages, the first page read
_rehydrateActivePageFromSource and _applyLoadedPageData (the first page read, given the same attempt)
reading the page, listing pages, putting it on the canvas
_loadInitialStrategy (the editor, web reload included)
waiting for sign-in to come back, the local open, the cloud open; these go through _unlessLeft, which ends the load once the reader has left the editor
I chose a token the open carries over a check where shared state is written, because the writes sit in four objects (open strategy, save state, upload queue, page session) and the waits sit in three functions; one throwing wait covers every write that follows it, including ones added later. test/open_attempt_test.dart reads those six functions and fails on any await that does not go through the helper; it fails when one is made plain again. What it does not see is a function they call that waits on its own, which is how the first version missed the page read; its header says so, and it checks the steps known today are handed the attempt.
The cloud snapshot notifier keeps its own older guard: it discards a read that finishes after clear() and does not start watching a strategy that is no longer the active one.
An open says whether it took. An open that gives way returns without opening, so both opens now return a bool. Mouse back and forward no longer record a place the reader never reached, and exporting from a card stops if its strategy did not open (the export saves the open canvas first). The editor's initial load already checked what was open; the quick switcher and cloud creation do not act on the result.
An editor that gave way stays if it shows the replacement. When another strategy opens while an editor's own is still loading, the editor used to treat that as a failed load and take itself off the screen. That is right when the other strategy has an editor of its own above (a share link arriving as the page starts). It was wrong when a share link, or back and forward, swapped the strategy in place: the editor that went was the one showing it. Giving way is now settled before the failure path, and the editor goes only when another editor shows what opened.
A local open clears a cloud read. When a cloud strategy is still being read, or is the one being replaced in place, a local open clears it as closing does, so its late answer or a disabled link cannot reach the local editor.
The held share code is what the address says. Holding a code now also points the address at it, so the held code, the stored code and the address always name the same link. Before, a second link held while the cloud was not ready left the address on the first, and a reload retried the wrong one.
Client only. No change to Convex, the library format, or sync.
Seen in a browser
Chromium driven by Playwright on a Linux box, release web builds served locally against dev Convex, two test accounts (an owner who made a view link and an edit link, and a reader). "Before" is main at b14efde; tag desktop-stable-v5.1.3+110 gave the same stuck screen.

Tests: the recorder test fails without the fix (the code stays held and the address keeps the link). The skeleton test taps the leave button. A snapshot test closes a strategy mid-read and fails without the change (the late read reopened it). open_attempt_test.dart is described above. The full suite passes locally (3,568 tests).
Review: CodeRabbit, Greptile and an Astra pass found five things between them; all are fixed in the later commits, and two Astra passes on the final shape found the page read, the callers and the address case above. The browser list above was rerun on the final head.
Seen in a Windows desktop build
The later commits touch the path every desktop user takes to open a strategy, so this ran in a Windows driver build of the final head.
editor-soak with its companion, rectangle-old-placement, pick-a-map and right-click-local all finish CLEAN.
Racing opens, by driver script: open a strategy and leave before it finishes then open another; open and close at once; double-click a card; the same strategy twice in a row; then reopen both. A driver tap takes about 0.6 s and a local load takes milliseconds, so the window was hit in a throwaway build of the same head that holds one strategy's load open for 4 s, before it is marked open ("early"), after its pages are read ("late"), or at its first page read, and can switch the guards off.

Known, left for a follow-up
Mouse back or forward to a strategy whose open throws drops that history entry. It did before this PR.
After a back that gave way to a newer open, the app's idea of the current place in history is stale until the next move.
The cloud snapshot notifier can install two shell watchers when the same strategy is opened twice with the first read still pending, keeping one handle. It predates this PR.
If a newer strategy starts opening in the same editor and the first one's page load then fails before the newer one has opened, the editor closes, and the newer strategy finishes opening with no editor showing it. It needs an in-place open and a failed load inside the same moment. Found by CodeRabbit on the last commit and not fixed here.
Not covered
Not run in Safari or Firefox, or on a phone.
The mouse side buttons were sent to the app only. A real side button also moves the browser's own history, which this PR does not change.
Reloading in the library after viewing a link still reopens the link, signed in or out, because the address still names it. That is today's behavior and keeps "sign in from the library to join" working.
Leaving mid-load was run in the browser with a slowed cloud (library stays, the next open works); that run waits on sign-in, not on the read. The read itself was held open only in the Windows build.
Leaving a loading editor with the browser's back button, which skips the app's own leave, still lets that load finish. Existing behavior.
A second reload while the first is still loading lands in the library: the store is cleared while the editor loads. Existing behavior, not touched here.
The camera dialog changing the address to / has a different cause and gets its own PR.

Summary by CodeRabbit
New Features
Shared strategy links stay synchronized with the page URL and can reopen the matching strategy after a reload.
A leave button is available on loading screens for touch and desktop layouts.
Loading screens can display a custom leading control.
Bug Fixes
Switching strategies or closing the editor during loading no longer lets late results replace the current view.
Navigation and local exports stop when a strategy fails to load.
Leaving during initial loading no longer triggers inappropriate error navigation, and cleared strategies remain cleared after pending reads finish.
A signed-in reader who opened a view link, went home, opened their own
strategy and reloaded was left on the editor's loading screen with a home
button that took no clicks. The address and the held share code still
named the link while the tab's store named their own strategy, so the
reload opened two editors and one lost.
The address and the held code now follow what is open: with the reader's
own strategy open the link is not what a reload reopens, and it is again
once its strategy is back on screen. A failed load takes its own editor
off the stack, and the loading screen has a working home button.
The change coordinates share-link reload state with cloud strategy selection. It guards asynchronous strategy opens and snapshot reads against stale results, adds route-aware handling for initial-load failures, and provides a leave button during loading.

Open results in navigation and export lib/widgets/mouse_navigation.dart, lib/widgets/strategy_tile/strategy_tile.dart, test/mouse_navigation_test.dart
Navigation reports success only when strategy loading succeeds. Local export stops when loading gives way. The navigation test checks that a failed open leaves the current strategy active and retries the same destination.
Initial-load exit and skeleton control lib/strategy_view.dart, lib/widgets/strategy_view_skeleton.dart, test/strategy_view_skeleton_test.dart
The editor tracks when the reader leaves during initial loading and applies route-aware failure handling. Loading layouts provide a leave button, and the skeleton can display it in place of its leading placeholder. The widget test checks button alignment and interaction.

Merge Risk: Moderate · up to d41cf
The reload fix works for the main scenarios. A rare failure while one strategy replaces another during loading could still close the editor that should show the new strategy. Two small back-navigation history inconsistencies also remain. Review the editor-removal edge case before merge.

Review of the first commit found three things.
The loading screen's home button lets a reader leave before the strategy
has loaded. The read went on, and its late answer opened the strategy
with no editor showing it and started its live reads. Closing a strategy
now discards a read still on its way, and a strategy that was closed or
gave way to another while it loaded does not open after the fact.
A load only counts as having given way when a strategy opened since it
started, so a real failure with an older strategy still open is reported.
The address is restored from the link whose strategy is on screen, not
from the held code, which can be a later link that could not be opened.
A second review found two more.
Opening a strategy set aside any held share code, including one that had
not opened yet (it arrived offline). The reload was that link's retry,
and it was lost. Only a link that has opened is set aside now.
On desktop, a strategy still being read from disk when the reader left
and opened another could finish late and replace the one they moved to.
A local load that gave way to a newer open or a close opens nothing.
On desktop a cloud strategy makes its storage folder before it is marked
open. A reader who left in that moment had it open again with no editor
showing. The open now checks once more that nothing newer took its place.

A strategy that gave way while its pages were being read still pointed the
upload queue at itself (cloud) or marked the save state saved (local),
which is now another strategy's. And a reader who left while the editor
waited for sign-in to come back could have the load start during the
editor's exit animation. Both stop now.
Three review rounds each found one more wait after which an open the
reader had left, or replaced with another, carried on: marking itself
open, marking another strategy saved, pointing the upload queue at
itself. The checks were written by hand after each wait, so the next
wait added would have had the same gap.
An open now carries one attempt (OpenAttempt) and waits only through it.
A wait that returns after the open gave way ends the open there, in one
place, so nothing after any wait can run for a superseded open. The page
session's part of an open takes the same attempt. The editor's own
initial load waits the same way against the reader having left.
A test reads the four functions that make up an open and fails on any
await that does not go through the helper.

Greptile has paused reviews on this repository — it used its 300 free open-source review credits for this billing period. Reviews resume automatically on November 28. To continue before then, an organization admin can keep reviews running past the free credits — those bill as normal usage.
A second review of the single-check shape found three things.
The page an open starts on was read and put on the canvas by a helper
that waited on its own, so it could replace the canvas of whatever the
reader had moved on to. It now takes the open's attempt, like the steps
above it, and the test that reads those functions lists it and says what
it does not see.
An open that gives way returns without opening. Both opens now answer
whether they took, so mouse back and forward no longer record a place
the reader never reached, and exporting from a card does not go on to
save the canvas of a different strategy.
A held share code, the stored code and the address now always name the
same link. Before, a second link held while the cloud was not ready left
the address on the first, and a reload retried the wrong one.

Restore the history target when opening the strategy throws.
openCloudStrategy throws a StateError when the cloud snapshot is unavailable. On the no-dirty, save, and discard paths in guardUnsavedStrategyExit, that exception is not caught. It escapes _navigateTo. _walkHistory has already removed the target from from, and it has no catch. The !moved branch that restores the target does not run, so the destination is lost from history. The error reaches the unawaited _goBack() call.
Catch the failure in _walkHistory, restore the target, and return:
Suggested fix
final target = from.removeLast();
if (!_isLocationAvailable(target)) {
// Folder or strategy has been deleted since; drop the stale entry.
continue;
}
- final bool moved = await _navigateTo(target);+ final bool moved;+ try {+ moved = await _navigateTo(target);+ } catch (_) {+ // The open failed. Keep the destination for the next Back press.+ from.add(target);+ return;+ }
if (!moved) {
Also report the failure to the user. Without a report, the navigation fails silently.

Left out of this PR on purpose. A throwing open dropped the history target before this PR too, and it is back/forward bookkeeping, not saved work. It becomes its own small item.

Reconcile the current location after a superseded Back walk.
When Back waits on an open and a newer open replaces the strategy, _isNavigating suppresses the location listener. If the older open then returns false, the !moved branch restores the target to from and leaves _currentLocation unchanged. The active strategy and _currentLocation now differ. The next successful Back stores the stale location as the forward destination.
Resolve the actual location after the walk clears _isNavigating. The current _recordLocationChange() is the natural place to do that.

Left out of this PR. It is not one safe call: after a walk to a cloud strategy the editor route is pushed before the strategy is open, so calling _recordLocationChange() at the end of the walk would read the folder as the location and record a move that did not happen. It joins the history item with the comment above.
The reason will be displayed to describe this comment to others. Learn more.
@SunkenInTime Agreed. My proposed call is unsafe: a cloud strategy route can be pushed before the strategy opens, so _recordLocationChange() could record the folder instead.
The history reconciliation remains a separate issue, so I won’t mark this finding as addressed. Would you like a new GitHub issue for it, or should it stay with the existing history item?
When another strategy opened while an editor's own was still loading,
the editor treated giving way as a failed load and took itself off the
screen. That is right when the other strategy has an editor of its own
above. It is wrong when a share link, or back and forward, swapped the
strategy in place: the editor that went was the one showing it, and the
strategy stayed open with nothing on screen for it. Giving way is now
settled before the failure path, and the editor stays when it is the one
showing what opened.
A local open also clears the cloud read, as closing does, so a cloud
strategy still being read cannot answer into a local one.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Compare the strategy source as well as its ID.
A local copy and a cloud strategy can share an ID. If the cloud strategy replaces a pending local open, the local editor treats the cloud ID as its own successful load and never reaches the route-removal check. The old editor can remain beneath the new one. Compare (source, strategyId) for the initial, previous, and current strategies. (raw.githubusercontent.com)

- Line 239: Update the catch path guarded by _gaveWayTo so it tracks whether the
initial open attempt was superseded by a newer in-place open; do not rely only
on strategyProvider.strategyId, which may still hold the old ID while the
replacement is pending. Preserve the editor when superseded, and remove it only
when the initial attempt remains current.

Keep the editor when a replacement open is still pending.
An initial strategy can be marked open while its page load waits. If a newer in-place open starts and the old page load then fails, the newer strategy has not yet written its ID. _gaveWayTo sees the old ID, returns false, and the catch path removes the only editor. The newer open can then finish with no editor to show it. Track whether the initial attempt was superseded; the current strategy ID cannot answer that question before the replacement commits.

A signed-in person on the web build who opened a view link, clicked home, opened their own strategy and reloaded was left on the grey loading screen. It never filled in and the home button did nothing; the only way out was editing the address. The live beta (5.1.3) does the same. Nothing was lost.
Cause
Two things remember what a reload should reopen, and after those steps they named different strategies:
/share/ICR-…, and the tab still held the share code, so the reload opened the link againTwo editors opened, one over the other. Both loaded into the same open-strategy state, one lost, and its failure popped the top editor instead of itself. What was left was an editor whose strategy never became the open one: a loading screen, which takes no clicks.
Fix
The address follows what is open. The recorder that stores the open cloud strategy for a reload (
openCloudStrategyRecorderProvider) now also tells the share link whether it is what a reload reopens: no while the reader's own strategy is open (the/share/…path leaves the address and the stored code is cleared), yes again when the strategy they read through the link is back on screen (both return). The link stays held in memory, so going back to that strategy in the same tab still reads through it. A reload now has one answer. A link that has not opened yet (it arrived offline) is left alone: a reload is its retry.A load that cannot finish ends somewhere usable.
One rule for a superseded open. Review kept finding one more wait after which an open the reader had left carried on (marking itself open, marking another strategy saved, pointing the upload queue at itself), so the last commit replaces the hand-written checks with one mechanism. An open carries an attempt (
OpenAttempt,lib/strategy/open_attempt.dart) and waits only throughopening.wait(...). A wait that returns after the open was closed or replaced throws there, and the one place that started the attempt (StrategyProvider._open) catches it, so nothing after any wait runs for a superseded open. The address follows the open strategy, so it is covered through it.The waits, all through the helper:
loadFromHive(local)openCloudStrategyinitializeForStrategy(the page step, given the same attempt)_rehydrateActivePageFromSourceand_applyLoadedPageData(the first page read, given the same attempt)_loadInitialStrategy(the editor, web reload included)_unlessLeft, which ends the load once the reader has left the editorI chose a token the open carries over a check where shared state is written, because the writes sit in four objects (open strategy, save state, upload queue, page session) and the waits sit in three functions; one throwing wait covers every write that follows it, including ones added later.
test/open_attempt_test.dartreads those six functions and fails on anyawaitthat does not go through the helper; it fails when one is made plain again. What it does not see is a function they call that waits on its own, which is how the first version missed the page read; its header says so, and it checks the steps known today are handed the attempt.The cloud snapshot notifier keeps its own older guard: it discards a read that finishes after
clear()and does not start watching a strategy that is no longer the active one.An open says whether it took. An open that gives way returns without opening, so both opens now return a bool. Mouse back and forward no longer record a place the reader never reached, and exporting from a card stops if its strategy did not open (the export saves the open canvas first). The editor's initial load already checked what was open; the quick switcher and cloud creation do not act on the result.
An editor that gave way stays if it shows the replacement. When another strategy opens while an editor's own is still loading, the editor used to treat that as a failed load and take itself off the screen. That is right when the other strategy has an editor of its own above (a share link arriving as the page starts). It was wrong when a share link, or back and forward, swapped the strategy in place: the editor that went was the one showing it. Giving way is now settled before the failure path, and the editor goes only when another editor shows what opened.
A local open clears a cloud read. When a cloud strategy is still being read, or is the one being replaced in place, a local open clears it as closing does, so its late answer or a disabled link cannot reach the local editor.
The held share code is what the address says. Holding a code now also points the address at it, so the held code, the stored code and the address always name the same link. Before, a second link held while the cloud was not ready left the address on the first, and a reload retried the wrong one.
Client only. No change to Convex, the library format, or sync.
Seen in a browser
Chromium driven by Playwright on a Linux box, release web builds served locally against dev Convex, two test accounts (an owner who made a view link and an edit link, and a reader). "Before" is main at b14efde; tag
desktop-stable-v5.1.3+110gave the same stuck screen./#/strategy_view/share/…/share/…on the shared one and to/on own; reload reopens the one on screenTests: the recorder test fails without the fix (the code stays held and the address keeps the link). The skeleton test taps the leave button. A snapshot test closes a strategy mid-read and fails without the change (the late read reopened it).
open_attempt_test.dartis described above. The full suite passes locally (3,568 tests).Review: CodeRabbit, Greptile and an Astra pass found five things between them; all are fixed in the later commits, and two Astra passes on the final shape found the page read, the callers and the address case above. The browser list above was rerun on the final head.
Seen in a Windows desktop build
The later commits touch the path every desktop user takes to open a strategy, so this ran in a Windows driver build of the final head.
