+Subject: [PATCH] ServiceWorker: Avoid double destruction of
+ ServiceWorkerObjectHost on connection error
+
+This CL avoids the case where ServiceWorkerObjectHost is destroyed twice
+on ServiceWorkerObjectHost::OnConnectionError() when Chromium is built
+with the GCC build toolchain.
+
+> How does the issue happen?
+
+ServiceWorkerObjectHost has a cyclic reference like this:
+
+ServiceWorkerObjectHost
+  --([1] scoped_refptr)--> ServiceWorkerVersion
+    --([2] std::unique_ptr)--> ServiceWorkerProviderHost
+      --([3] std::unique_ptr)--> ServiceWorkerContainerHost
+        --([4] std::unique_ptr)--> ServiceWorkerObjectHost
+
+Note that ServiceWorkerContainerHost manages ServiceWorkerObjectHost in
+map<int64_t version_id, std::unique_ptr<ServiceWorkerObjectHost>>.
+
+When ServiceWorkerObjectHost::OnConnectionError() is called, the
+function removes the reference [4] from the map, and destroys
+ServiceWorkerObjectHost. If the object host has the last reference [1]
+to ServiceWorkerVersion, the destruction also cuts off the references
+[2] and [3], and destroys ServiceWorkerProviderHost and
+ServiceWorkerContainerHost.
+
+This seems to work well on the Chromium's default toolchain, but not
+work on the GCC toolchain. According to the report, destruction of
+ServiceWorkerContainerHost happens while the map owned by the container
+host is erasing the ServiceWorkerObjectHost, and this results in crash
+due to double destruction of the object host.
+
+I don't know the reason why this happens only on the GCC toolchain, but
+I suspect the order of object destruction on std::map::erase() could be
+different depending on the toolchains.
+
+> How does this CL fix this?
+
+The ideal fix is to redesign the ownership model of
+ServiceWorkerVersion, but it's not feasible in the short term.
+
+Instead, this CL avoids destruction of ServiceWorkerObjectHost on
+std::map::erase(). The new code takes the ownership of the object host
+from the map first, and then erases the entry from the map. This
+separates timings to erase the map entry and to destroy the object host,
+so the crash should no longer happen.

+
+This is part of an effort to rewrite calls to utf8() and set_utf8()
+(in RE2::Options) as calls to encoding() and set_encoding(),
+respectively. utf8() and set_utf8() have been marked as the "legacy"
+interface since 2008, so it is long past time that we get rid of them.

+Subject: [PATCH] Make some of blink custom iterators STL compatible.
+
+Blink has recently started using functions like std::any_of with some of
+the custom iterators it provides. On Linux this works in the default
+setup using libcxx, but fails with even the most recent versions of
+libstdc++. In all cases the error message (text in bug report) complains
+about lack of matching std::__iterator_category definition.
+
+From what I understand the error message is basically saying those
+iterators are not STL compatible due to missing traits as described
+in https://en.cppreference.com/w/cpp/iterator/iterator_traits. Such
+traits are provided by custom iterators defined in //base, or //cc.
+
+This patch adds the necessary traits to iterators that are currently
+affected by this problem.
+
