+Subject: build: disable print_content_analysis
+
+Print Content Analysis enables enterprise users to scan to-be-printed
+pages and documents for sensitive data if the OnPrintEnterpriseConnector
+policy is enabled. A conversation with the Chromium team confirmed
+this feature was intended for enterprise Chrome users and not embedders,
+so we're disabling it to prevent build issues/additional unneeded files.
+
+This patch can be removed when enable_print_content_analysis can be more
+easily enabled or disabled by default with buildflags.

patches/chromium/disable_compositor_recycling.patch

@@ -6,10 +6,10 @@ Subject: fix: disabling compositor recycling
 Compositor recycling is useful for Chrome because there can be many tabs and spinning up a compositor for each one would be costly. In practice, Chrome uses the parent compositor code path of browser_compositor_view_mac.mm; the NSView of each tab is detached when it's hidden and attached when it's shown. For Electron, there is no parent compositor, so we're forced into the "own compositor" code path, which seems to be non-optimal and pretty ruthless in terms of the release of resources. Electron has no real concept of multiple tabs per window, so it should be okay to disable this ruthless recycling altogether in Electron.

+Subject: feat: Add data parameter to ProcessSingleton
+
+This patch adds an additional_data parameter to the constructor of
+ProcessSingleton, so that the second instance can send additional
+data over to the first instance while requesting the ProcessSingleton
+lock.
+
+On the Electron side, we then expose an extra parameter to the
+app.requestSingleInstanceLock API so that users can pass in a JSON
+object for the second instance to send to the first instance.

-From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
-From: Raymond Zhao <raymondzhao@microsoft.com>
-Date: Tue, 7 Sep 2021 14:54:25 -0700
-Subject: feat: Add data transfer mechanism to requestSingleInstanceLock flow
-
-This patch adds code that allows for the second instance to send
-additional data to the first instance, and for the first instance
-to send additional data back to the second instance, during the
-app.requestSingleInstanceLock call.
-
-Firstly, this patch adds an additional_data parameter
-to the constructor of ProcessSingleton, so that the second instance
-can send additional data over to the first instance
-while requesting the ProcessSingleton lock.
-
-Then, we add additional processing to the second-instance event, both
-so the first instance can receive additional data from the second
-instance, but also so the second instance can send back additional
-data to the first instance if needed.

+Subject: feat: filter out non-shareable windows in the current application in
+ ScreenCaptureKitDevice
+
+This patch ensures that windows protected via win.setContentProtection(true) do not appear in full display captures via desktopCapturer.  This patch could be upstreamed but as the check is limited to in-process windows it doesn't make a lot of sense for Chromium itself.  This patch currently has a limitation that it only function for windows created / protected BEFORE the stream is started.  There is theoretical future work we can do via polling / observers to automatically update the SCContentFilter when new windows are made but for now this will solve 99+% of the problem and folks can re-order their logic a bit to get it working for their use cases.

+Subject: fix: adapt exclusive_access for electron needs
+
+This patch is necessary in order to properly enable
+navigator.keyboard.{(un)?lock}() functionality. We don't have a concept
+of PermissionManager nor of a Profile, so this would not affect usage of
+the API.
+
+We also need to ensure that NotifyExclusiveTabAccessLost is called
+on all platforms in FullscreenController::ExitFullscreenModeInternal()
+and not just macOS, since Electron's native window impls report state
+change fairly instantly as well, and so pressing escape won't work on
+Linux or Windows to un-fullscreen in some circumstances without this
+change.
