Walkthrough

The CefErrorCode enum was updated to add new error codes for fingerprinting protection, self-signed local network certificates, and proxy requirements. One legacy certificate error code was removed, and documentation for an existing error was clarified. The range endpoint for certificate errors was adjusted to reflect these changes.

Changes

File	Change Summary
CefSharp/Enums/CefErrorCode.cs	Added BlockedByFingerprintingProtection, CertSelfSignedLocalNetwork, and ProxyRequired error codes; removed CertSymantecLegacy; updated CertEnd value; clarified UnexpectedContentDictionaryHeader summary.

Poem

In the meadow of code, new errors appear,
For proxies, certs, and privacy clear.
Old Symantec roots now hop away,
Fingerprinting blocked—keep snoops at bay!
With headers refined and boundaries reset,
This enum’s a garden, the finest yet.
🐇✨

Tip

⚡️ Faster reviews with caching

• CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.

Enjoy the performance boost—your workflow just got faster.

CefSharp/Enums/CefErrorCode.cs (6)

204-207: New error code for fingerprinting protection looks good.

This properly adds the new Chromium error code for requests blocked by fingerprinting protections.

---

797-797: Correctly removed legacy error code.

The removal of the Symantec legacy certificate error code (CERT_SYMANTEC_LEGACY) with a comment noting its removal matches the upstream Chromium changes.

---

811-815: New certificate error code for self-signed local network certificates added correctly.

This properly adds the error code for self-signed certificates used with RFC1918 IP literals or .local URLs, matching the upstream Chromium definition.

---

825-825: CertEnd value updated correctly.

The CertEnd value was properly updated from -219 to -220 to reflect the addition of the new certificate error code. This maintains the enum's internal structure.

---

1114-1117: New proxy requirement error code looks good.

The addition of the ProxyRequired error code (-368) for signaling IPP proxy requirements is correctly implemented.

---

1223-1223: Error description clarified appropriately.

The description for UnexpectedContentDictionaryHeader has been updated to more accurately describe the error condition related to dictionary compressed streams.
