A change was made in the SMTP client creation process to add more robust error handling. The new logic checks if the client is null after being created and, if true, returns an error. This update can help prevent potential null pointer exceptions in runtime, ultimately leading to more stable application.
Added a nil check in the IsTemp method in senderror.go to prevent runtime errors when method is called on a nil object. The method now immediately returns false if it is invoked on a nil *SendError, ensuring the program's robustness against potential misuse. This increases the robustness and readability of the
Added a condition to prevent assignment of an empty address list to the 'HeaderFrom' scenario. This eliminates potential runtime errors when trying to access an nonexistent element of a slice.
Adjusted error handling in the sendmail execution part by reusing the 'err' variable, promoting cleaner, more readable code.
Tests for new mail address handling methods have been updated to use {Name:"", Address: "email@example.com"} format for initializing the []*mail.Address slices, instead of the previous shorthand {"", "email@example.com"}. This was done to increase code clarity and explicitness.
Added `time` import in the eml_test.go and added two new test use-cases: `exampleMailPlainNoEncInvalidDate` and `exampleMailPlainNoEncNoDate`. The `exampleMailPlainNoEncInvalidDate` is used to check if the parser can correctly handle email with invalid date. Meanwhile, `exampleMailPlainNoEncNoDate` checks if the parser can correctly add the current date to an email that didn't specify a date. This will improve the parser's resilience and flexibility in handling various email scenarios.
The test emails in the eml_test.go file have been updated with more diverse fields, including variations of encoding types. These changes help improve the robustness of our parser tests by evaluating its function with a wider range of email structures. Tests including quoted-printable and base64 encoded emails have been added.
A new test `TestEMLToMsgFromString` was added to "eml_test.go". This test asserts the proper functionality of `EMLToMsgFromString` method that allows us to parse EMLs directly from a string input. This test is a necessary part of ensuring the functionality and reliability of our EML parsing process.
Added two new methods `EMLToMsgFromString` and `EMLToMsgFromReader` in "eml.go". They allow EML parsing directly from a given string and a reader object, increasing overall functionality and versatility of the EML parsing process. This will enable the users to parse EML documents more flexibly."
This commit changes the usage of error value and improves the string comparison for encoding types in EML file parsing. It ensures file closure after read operations to avoid memory leaks. Error messages are made dynamic for improved error reporting. Comments on function has also been made more descriptive.
Added support for quoted-printable encoding in email parser to increase its functionality. The change includes a case handling feature for 'EncodingQP' and related conversions to allow for proper message body reading and encoding setting. This improves the robustness and the scope of email content types that the parser can handle."
Renamed field 'Mime10' to 'MIME10' across multiple files for canonical representation and consistency with standard MIME naming format in the protocol."
Added "References" header field to cover more potential use cases and enhance versatility. This field will allow applications to track series of related messages.
Test for "References" field has also been added for validation.
Also included are string methods for Content-type objects with relevant tests, ensuring accurate string conversion. Unnecessary duplicate method of string conversion for Charset has been removed to streamline the code and improve readability.
We can no parse simple mails (multipart is not working yet). The existing implementation was made more efficient by refactoring the EML file parsing and header extraction mechanism. Added 'strings' and 'bytes' packages to facilitate these changes. Previously, headers and body were parsed separately which was unnecessarily complex and increased the chance of errors. Now, with the new function 'readEML' and the helper function 'parseEMLBodyParts', we are able to parse headers and body together which not only simplifies the code but also increases its reliability. Specifically, 'bytes.Buffer' now helps us capture body while parsing, which removes need for separate handling. Additionally, certain headers like 'charset' and body types are also accounted for in the new implementation, enhancing the completeness of information extracted from EML files.
The diff modifies how the email library handles the extraction of the mime media type from an email header. It uses the mime.ParseMediaType function to parse the content type header. The function gives back the media type as a string and a mapping of different associated parameters. This mapping was previously just printed, but now the charset parameter is also used for setting the charset of the email if it exists.
Added two new functions `EMLToMsg` and `readEML` to the `mail` package. `EMLToMsg` function opens and parses a .eml file and returns a pre-filled Msg pointer. `readEML` opens an EML file and uses net/mail to parse the header and body. These changes are made to provide support for EML file parsing, which is a common requirement in many email-based applications.
This commit introduces a new type 'JSONlog' that satisfies the Logger interface for structured JSON logging. This includes new methods 'Debugf', 'Infof', 'Warnf' and 'Errorf' to log messages at different levels and an associated test 'jsonlog_test.go' to ensure correct functionality. This enhances the logging functionality by providing clarity in logs and eases debugging process.
Moved Level constants and directionPrefix() function from log/stdlog.go to log/log.go. This change improves the organization of the code by grouping log level constants and related functions in the same file. Furthermore, this removes redundancy and ensures consistency of log level across different files.
The deleted .idea XML configuration files (markdown.xml, modules.xml, Project_Default.xml) were not required for the functioning of the project. Removing these files helps in reducing clutter and simplifying the project structure. Also, these files can often contain user-specific settings or paths, and may cause conflicts when working in a team.
This commit updates the Go version from 1.20 to 1.21 on three GitHub workflow files: golangci-lint.yml, codecov.yml, and sonarqube.yml. The change ensures we use the latest Go version which is more efficient and comes with additional features, leading to improved project performance.
The .idea/vcs.xml file was deleted because it is not needed for the project. It was initially created by the IntelliJ IDEA but we're managing version control configurations through another way, making this file redundant.
Deleted the `.idea/go-mail.iml` file which was committed in error and should not be part of the source code repository. Updated the `.gitignore` file to ignore the whole `.idea` directory, since it contains configuration files that are specific to each developers environment and not required for the project build. The changes in the repository will now make it more clutter-free and prevent unintentional commits of unnecessary files in the future.
In the updated version of msgwriter.go, an additional error handling process has been included. If an error is detected when creating a new part in the message writer, this error is stored and prevents executing the writeBody function. This fixes nil pointer dereference in `mw.writeBody` if an error occured previously.

The logging system in the smtp.go and log package has been refactored. A new custom log type `Log` was introduced, that includes the message direction, format and arguments. The `Logger` interface and the `Stdlog` implementation were modified to accept this new type. This change provides a clearer understanding of message direction inside logs, allowing for easier debugging and reduced complexity. This change does not affect features or disrupt user functionality. Additionally, it allows for custom implementations of the log.Logger interface to without being forced to use the C --> S/C <-- S direction logging.
A `const CallDepth` placeholder has been introduced and has been set to 2. This is used as an argument in Output method calls in various log levels like debug, info, warn, and error in place of previously hardcoded '2'. This change improves the readability of the code. The '2' represented the call depth of log.Logger's Output method, which wasn't immediately clear with the hardcoded value.
