From 5ce723f4791c18f129f3f7e763522a165cd32b78 Mon Sep 17 00:00:00 2001 From: Tom Clarke Date: Tue, 7 Oct 2025 16:52:30 -0400 Subject: [PATCH 01/11] Upgrade to Phoenix LiveView 1.1 Upgrade phoenix_live_view from ~> 1.0.18 to ~> 1.1.0 to support template resolution changes and new rendering optimizations. Add lazy_html dependency for HTML parsing in tests, required by LiveView 1.1's test infrastructure. Use override: true for phoenix_live_view as live_view_native_test_endpoint requires an older version (~> 1.0.0-rc.8). --- mix.exs | 3 ++- mix.lock | 12 ++++++++---- 2 files changed, 10 insertions(+),

Phoenix LiveView 1.1 introduced a template sharing optimization where comprehensions reference templates by integer position. When merging diffs from different renders, these position references can collide. The fix resolves integer template position references to literal static part lists during the merge operation, preventing collisions. This brings the diff merging behavior in line with Phoenix LiveView 1.1's implementation by: - Adding module attributes @template, @keyed, @keyed_count - Adding template resolution clause to deep_merge_diff/2 - Implementing resolve_templates/2 helper functions --- lib/live_view_native/test/view_tree.ex | 51 ++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) diff --git a/lib/live_view_native/test/view_tree.ex b/lib/live_view_native/test/view_tree.ex index 02276dc..9d5029e 100644 --- a/lib/live_view_native/test/view_tree.ex +++ b/lib/live_view_native/test/view_tree.ex @@ -4,6 +4,9 @@ defmodule LiveViewNativeTest.ViewTree do @phx_component "data-phx-component" @static :s @components :c + @template :p + @keyed :k + @keyed_count :kc @stream_id :stream def ensure_loaded! do @@ -284,6 +287,12 @@ defmodule LiveViewNativeTest.ViewTree do update_in(rendered[@components], &Map.drop(&1, cids)) end + # We resolve any templates when merging, because subsequent patches can + # contain more templates that are not compatible with previous diffs. + # This prevents template position collisions from breaking rendering. + defp deep_merge_diff(target, %{@template => template} = source), + do: deep_merge_diff(target, resolve_templates(Map.delete(source, @template), template)) + defp deep_merge_diff(_target, %{@static => _} = source), do: source @@ -293,6 +302,48 @@ defmodule LiveViewNativeTest.ViewTree do defp deep_merge_diff(_target, source), do: source + # Template resolution helpers - convert template position references to literal static parts + defp resolve_templates(%{@template => template} = rendered, nil) do + resolve_templates(Map.delete(rendered, @template), template) + end + + defp resolve_templates(%{@static => static} = rendered, template) when is_integer(static) do + resolve_templates(Map.put(rendered, @static, Map.fetch!(template, static)), template) + end + + defp resolve_templates(%{@keyed => keyed} = rendered, template) do + keyed = + case keyed[@keyed_count] do + 0 -> + keyed + + count -> + for pos <- 0..(count - 1), reduce: keyed do + acc -> + case keyed[pos] do + nil -> acc + value -> Map.put(acc, pos, resolve_templates(value, template)) + end + end + end + + rendered + |> Map.put(@keyed, keyed) + |> Map.delete(@template) + end + + defp resolve_templates(%{} = rendered, template) do + Enum.reduce(rendered, rendered, fn + {key, value}, acc when is_integer(key) -> + Map.put(acc, key, resolve_templates(value, template)) + + {_, _}, acc -> + acc + end) + end + + defp resolve_templates(other, _template), do: other + def extract_streams(%{} = source, streams) when not is_struct(source) do Enum.reduce(source, streams, fn {@stream_id, stream}, acc -> [stream | acc] From 8e1809beb1e966bd17a1ce8cff1cd813073cd8c0 Mon Sep 17 00:00:00 2001 From: Tom Clarke Date: Tue, 7 Oct 2025 17:47:23 -0400 Subject: [PATCH 04/11] Reverted unnecessary change to client proxy --- lib/live_view_native/test/client_proxy.ex | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/lib/live_view_native/test/client_proxy.ex b/lib/live_view_native/test/client_proxy.ex index 7aa0cf7..0979aee 100644 --- a/lib/live_view_native/test/client_proxy.ex +++ b/lib/live_view_native/test/client_proxy.ex @@ -89,8 +89,7 @@ defmodule LiveViewNativeTest.ClientProxy do # We can assume there is at least one LiveView # because the live_module assign was set. - response_html = if is_struct(response_body, LazyHTML), do: LazyHTML.to_html(response_body), else: response_body - root_markup = ViewTree.parse(response_html) + root_markup = ViewTree.parse(response_body) {id, session_token, static_token, redirect_url} = case Map.fetch(opts, :live_redirect) do From 6735db1155a6c3eb54205249cefe022b5c13cb49 Mon Sep 17 00:00:00 2001 From: Tom Clarke Date: Tue, 7 Oct 2025 17:59:35 -0400 Subject: [PATCH 05/11] Reverted unnecessary change to client proxy --- test/live_view_native/test/view_tree_test.exs | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/test/live_view_native/test/view_tree_test.exs b/test/live_view_native/test/view_tree_test.exs index aaa901c..1ba7a8a 100644 --- a/test/live_view_native/test/view_tree_test.exs +++ b/test/live_view_native/test/view_tree_test.exs @@ -137,6 +137,10 @@ defmodule LiveViewNative.ViewTreeTest do new_markup = ViewTree.to_markup(new_markup) + IO.puts("\n=== ACTUAL MARKUP ===") + IO.puts(new_markup) + IO.puts("=== END MARKUP ===\n") + refute new_markup =~ ~S(a) assert new_markup =~ ~S(a) assert new_markup =~ ~S(inner) From d23ca825fee117f84eeadb612497e0d8ca528e71 Mon Sep 17 00:00:00 2001 From: Tom Clarke Date: Tue, 7 Oct 2025 18:14:11 -0400 Subject: [PATCH 06/11] Add diff merge tests and improve keyed comprehension handling Add test/live_view_native/test/diff_test.exs with 5 tests covering template resolution and diff merging behavior, matching Phoenix LiveView 1.1's test suite.
