Reason why a cookie was removed from the cookie store The user explicitly requested that we delete a cookie The value of the cookie was overwritten by a new value The cookie expiration time passed The cookie was evicted during garbage collection (replaced by domain_evicted/global_evicted below) The backing store had two copies of the cookie so one was removed (i.e. problems writing the backing store database) The cookie deletion should not be recorded because it occurred, e.g., during shutdown (the fact that these values showed up in the histogram is a bug, since fixed) The cookie was evicted during per-domain/eTLD+1 garbage collection The cookie was evicted during whole store garbage collection. The cookie evicted during per-domain/eTLD+1 garbage collection, and would have been evicted by the global garbage collection process (because they hadn't been accessed recently enough). The cookie evicted during per-domain/eTLD+1 garbage collection, and would not have been evicted by global metrics as well (because they had been accessed recently enough to save). The cookie deletion occurred because the server overwrote it with an already expired cookie (this is a common idiom for server deletions of cookies).

Coarse MIME type classification for CORB decisions. https://mimesniff.spec.whatwg.org/#html-mime-type. https://mimesniff.spec.whatwg.org/#xml-mime-type, except `image/svg+xml` and `application/dash+xml`. https://mimesniff.spec.whatwg.org/#json-mime-type. text/plain Other, unrecognized MIME type. Blocked if sniffing finds a JSON security prefix. Used for content types that are unlikely to be incorrectly applied to images, scripts and other legacy no-cors resources (which consequently don't need any confimation sniffing). For example: `application/pdf`, `application/zip`, etc. Whether CORB blocking might have been caused by treating |request_initiator| as opaque when |request_initiator_origin_lock| is incompatible (as may be the case for HTML Imports). CORB blocked either an empty response, or a 4xx/5xx response. CORB blocked a response after forcing |request_initiator| to be treated as opaque (because it was incompatible with |request_initiator_origin_lock|). This case is most likely to be hit with HTML Imports. Coarse MIME type classification for CORB decisions. The result of trying to initialize the CoreAudio dispatch override hotfix.

This list should be aligned with CRAS: https://chromium.googlesource.com/chromiumos/third_party/adhd/+/main/cras/src/server/cras_server_metrics.h This enum describes the timing of a renderer crash in relation to whether a sad frame was visible. Whether a subframe is "visible" is currently defined as 1) in visible, non-occluded WebContents and 2) with a non-empty viewport intersection rect. The renderer crashed while the subframe was visible. The renderer crashed while the subframe was hidden, but later the frame became visible (the tab was foregrounded, the frame was scrolled into view, the frame was resized, etc.). The renderer crashed while the subframe was hidden, and the frame was never shown afterwards (e.g. until eventually being discarded when the whole tab is navigated away). The renderer crashed while the subframe was hidden, and the frame became visible while an ancestor frame had a pending load. This form of sad frame is not as bad for user experience as ShownAfterCrashing, since the sad frame is expected to disappear shortly when the ancestor frame finishes navigation. One common case where this is expected to happen is when a crashed subframe appears on a hidden tab, which will mark the tab for reload, and then the user switches to this tab. The tab will start reloading, but the crashed subframe may become visible momentarily before the reload completes. List of status types of Noise Cancellation for the supported audio device.

During a page fault, the target address refers to a memory object that has been destroyed. This failure is permanent. During a page fault, the memory object indicated that the data could not be returned. This failure may be temporary; future attempts to access this same data may succeed, as defined by the memory object. The receive right is not a member of a port set. The name already denotes a right in the task. The operation was aborted. Ipc code will catch this and reflect it as a message error. The name doesn't denote a right in the task. The name denotes a right, but not an appropriate right. A blatant range error. The task already has send or receive rights for the port under another name. An attempt was made to supply "precious" data for memory that is already present in a memory object. A page was requested of a memory manager via memory_object_data_request for an object using a MEMORY_OBJECT_COPY_CALL strategy, with the VM_PROT_WANTS_COPY flag being used to specify that the page desired is for a copy of the object, and the memory manager has detected the page was pushed into a copy of the object while the kernel was walking the shadow chain from the copy to the object. This error code is delivered via memory_object_data_error and is handled by the kernel (it forces the kernel to restart the fault). It will not be seen by users. A strategic copy was attempted of an object upon which a quicker copy is now possible. The caller should retry the copy using vm_object_copy_quickly. This error code is seen only by the kernel.

The attempt was canceled by the request coordinator. This is triggered when the user cancels an in-flight offlining attempt, and will always result in BackgroundSavePageResult::USER_CANCELED. Loading was canceled by various pre-render monitoring. These include when window.open was called, when audio is detected, etc. The attempt resulted in a retriable loading failure. The system or Chrome encountered an error (e.g. render killed, WebContents destroyed). The attempt failed because save did not succeed. The attempt failed because chrome is now operating in the foreground on a svelte device. The attempt failed because the particular attempt ran out of time. The attempt resulted in a non-retriable loading error. This is mostly deprecated as of 4/2017 because a fickle network and a good page might result in the same errors as a bad page with invalid URL. The attempt resulted in a loading failure but we've reason to believe we shouldn't try something else for a little while: i.e. we failed because a renderer crashed or we got INTERNET_DISCONNECTED as the network error. The offliner was asked to attempt something when it's not ready. The request coordinator failed updating the status of the request in the queue. The attempt is aborted. Called when the background scheduler stops the processing. The attempt succeeded, but only as a result of snapshotting on the last retry and we have already received PrimaryMainDocumentElementAvailable. Note that if we're already in the middle of snapshotting, we will record SAVED. The quality of the page is presumed to be lower. The browser was killed for reasons such as OOM, swiped out, or crashed. The attempt resulted in a retriable loading failure. We encountered a network error (e.g. NETWORK_CHANGED, TIMED_OUT). Because fickle networks make network errors unreliable, an incorrectly typed URL will also result in retriable loading failure. The attempt resulted in a retriable loading failure. We encountered an error page (e.g. 404 page). Background loading of the page was deferred because its URL matches the one on the active tab URL. The attempt will be retried later.

Filling only happens in iframes if all parent frames PSL-match the security origin of the iframe containing the password field. Passwords are not filled into fields that are not editable. The username field contains a string that does not match the username of any available credential. This typically indicates placeholder values. No credential was filled due to mismatches with the username. This can happen in a number of cases: In case the username field is empty and readonly. In case of a username-first-flow where a user's credentials do contain a username but the form contains only a password field and no username field. In case of change password forms that contain no username field. In case the user name is given on a page but only PSL matched credentials exist for this username. There may be further cases. Renderer was instructed to wait until user has manually picked a credential. This happens for example if the session is an incognito session, the credendial's URL matches the mainframe only via the PSL, the site is on HTTP, or the form has no current password field. PasswordManager.FirstWaitForUsernameReason records the root causes. No fillable elements were found, only possible for the old form parser. User is browsing in incognito mode. A credential exists for a PSL matched site but not for the current security origin. Form is suspected to be a password change form.

User is browsing with the Fill On Select feature enabled. Re-authenticaion for filling passwords is required. Password field is already filled in and it doesn't look like a placeholder. A credential exists for an affiliated matched site but not for the current security origin. The form acccepts WebAuthn credentials from an active WebAuthn request. User needs to reauthenticate using biometric. The form is in a cross origin iframe. This enum records the type of a given HTTP credential. Depending on its username and the password, an HTTP credential can have no matching, an equivalent or a conflicting HTTPS credentials. Also the corresponding website can be served with or without HSTS enabled. A credential exists for a PSL matched site but not for the current security origin. A credential exists for an affiliated android app but not for the current security origin. A credential exists for an affiliated site but not for the current security origin. Deprecated 09/2021.
