Introduce a new test case to verify that `UnmarshalString` fails when given an invalid string. This ensures the robustness of the error handling in the `SMTPAuthType` unmarshalling process.
Included the SPDX license identifiers for copyright and license type at the beginning of the auth_test.go file. This ensures clear licensing information is provided and helps with automated license compliance.
Implement the fig.StringUnmarshaler interface for SMTPAuthType to map strings to corresponding authentication types. Added comprehensive unit tests to ensure correct functionality for all supported auth type strings.
Corrected multiple instances of "mechansim" to "mechanism" in the comments describing SASL authentication methods to improve readability and maintain code quality.
Fix a typo in smtp_test.go's comment from "challanges" to "challenges" to improve readability and accuracy of documentation. This change does not affect the code's functionality.
Corrected spelling errors in comments for "challenge" and "compatibility" to improve clarity. This ensures better understanding and adherence to the documented IETF draft standard.
Introduced TestClient_SetLogAuthData to verify the proper behavior of the SetLogAuthData method in both client and SMTP tests. This ensures that logAuthData is enabled or disabled as expected, increasing code reliability.
Added a new option and methods to enable logging of SMTP authentication data. Updated documentation to indicate caution when using this feature due to potential data protection risks.
Added the `logAuthData` flag to enable conditional logging of SMTP authentication data. Introduced the `SetLogAuthData` method for clients to toggle this flag. Adjusted existing logging logic to respect this new configuration.
Add a boolean flag `authIsActive` to manage redaction of sensitive authentication information in debug logs. When this flag is true, authentication details are replaced with `<auth redacted>`.
Renamed environment variables from TEST_USER and TEST_PASS to TEST_SMTPAUTH_USER and TEST_SMTPAUTH_PASS for clarity and consistency in setting SMTP authentication credentials. This change ensures that the correct credentials are applied during tests.
This commit fixes a regression introduced in v0.5.0. We now set the default SMTPAuthType to NOAUTH in NewClient. Enhanced documentation and added test cases for different SMTP authentication scenarios.
Updated the SetMessageID method to generate a "Message-ID" using a
single randomly generated string combined with the hostname, replacing
the prior complex format that included process ID and multiple random
numbers. This change simplifies the code of the generated IDs.
Revised the character set to include a larger variety of symbols and adjusted the bit size calculations to correspond with the new set size. This ensures more efficient and secure random string generation by effectively utilizing the bitmask.
Removed `randNum` functions and associated tests from `random_119.go`, `random_121.go`, and `random_122.go`. These functions are no longer necessary. Additionally, replaced `TestRandomNum` and `TestRandomNumZero` with benchmarking for `randomStringSecure`.
Updated the TLSPolicy type documentation to improve clarity and consistency. Enhanced the String method with detailed commentary and return value explanation, ensuring it better adheres to the fmt.Stringer interface.
Improved comments for better clarity and detail in SendError-related methods and fields. Updated comments provide more in-depth explanations of functionality, parameters, return values, and usage.
Improved documentation for the Reader struct, its methods, and error handling. Added detailed explanations for `Read`, `Error`, `Reset`, and `empty` functions to better describe their parameters, return values, and behavior.
Expanded randNum function comments to provide detailed behavior and usage across different Go versions. Enhanced the randomStringSecure function doc to explain its cryptographic secure implementation and error handling.
Enhanced the documentation of `Part` struct and its methods to provide clearer explanations, including parameter and return descriptions. This improves code readability and helps developers understand the functionality and usage of each method.
Streamline msgWriter by adding detailed documentation for each method and constant. This includes parameter descriptions, return values, and references to relevant RFCs, improving code readability and maintainability.
Updated the documentation for NumString, XPrioString, and String methods in the Importance type to provide clearer descriptions of their behavior and return values. Enhanced comments for better readability and maintainability of the code.
Updated documentation for the `File` struct and its methods, providing clearer explanations and detailed parameter and return descriptions. Improved readability and consistency of comments across the codebase.
Enhanced comments for String methods on Charset, ContentType, and Encoding types. Detailed the purpose and usage of each method, emphasizing their role in formatted output and logging.
Added detailed doc comments to EML parsing functions, specifying parameters, return values, and providing thorough explanations of functionalities to improve code understandability and maintainability. This helps future developers and users comprehend the usage and behavior of these functions more effectively.
Updated the documentation for the Send method in client_119.go and client_120.go to provide clearer explanations, include detailed descriptions of parameters, and specify return values. Ensured consistency across files by elaborating on error handling and connection checks.
