This change ensures that coverage data files are not tracked by Git. The addition helps keep the repository clean from auto-generated coverage reports.
Improved the test suite for the Base64LineBreaker. Tests are now written more consistently. Maintainability and readability have been improved as well.
Switched ErrNoOutWriter from a string constant to an error object for improved error handling consistency. This change enhances clarity and reduces the risk of error handling inconsistencies in the future.
Updated the log level from error to debug for the client.Close() call failure in client_test.go. This change helps reduce noise in test output when the server connection fails.
Update defer statements to log errors if client fails to close in smtp_test.go. Additionally, add a return statement to avoid further errors after a failed SendMail operation.
Introduced new test functions TestAuthPlainNoEnc and TestAuthLoginNoEnc in smtp_test.go to verify behaviors of PlainAuth and LoginAuth without TLS encryption. These tests ensure that authentication mechanisms handle non-encrypted and diverse server configurations correctly.
Updated PlainAuth and LoginAuth calls in smtp_test.go and example_test.go to include a 'skipTLS' boolean parameter. This ensures consistent function signatures throughout the test cases and examples.
Implemented an option to allow SMTP LOGIN authentication over unencrypted channels by introducing a new `SMTPAuthLoginNoEnc` type. Updated relevant functions and tests to handle the new parameter for unsecured authentication.
Implemented a new SMTPAuthPlainNoEnc option to allow PLAIN authentication over unencrypted connections. Refactored the PlainAuth function to accept an additional allowUnencryptedAuth parameter. Updated relevant tests to cover the new authentication method.
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`.
