Philadelphia v1.3.1 Release Notes

Release Date: 2022-05-21 // almost 2 years ago
    • 🛠 Fix MsgSeqNum(34) handling on SequenceReset(4) (Vadim Platonov, Jussi Virtanen)

    Do not increment the outgoing MsgSeqNum(34) value when sending a SequenceReset(4) message.

    • 👌 Improve Logout(5) handling (Vadim Platonov, Jussi Virtanen)

    Handle a Logout(5) message with too low MsgSeqNum(34) value, but still send a ResendRequest(2) message when receiving a Logout(5) message with too high MsgSeqNum(34) value.


Previous changes from v1.3.0

    • 👌 Improve FIXValueTest (Jussi Virtanen)

    Make test cases that rely on the side effect of an attempt to read an incomplete value from a buffer partially populating the value container to actually read a complete value.

    Improve test coverage for all FIXValue methods.

    • ⚡️ Optimize FIXValue (Jussi Virtanen)

    Decrease the bytecode size of the FIXValue#setDigits method from 44 to 31 bytes, which is within HotSpot's default maximum inline size of 35 bytes. This makes the following methods faster:

    • FIXValue#setCheckSum
    • FIXValue#setDate
    • FIXValue#setTimeOnly
    • FIXValue#setTimestamp

    Decrease the bytecode size of the FIXValue#setInt method from 102 to 79 bytes, making it faster.

    Decrease the bytecode size of the FIXValue#setFloat method from 177 to 161 bytes, making it faster.

    • ➕ Add FIXMessage(FIXConfig) (Jussi Virtanen)

    • ➕ Add FIXValue#toString (Jussi Virtanen)

    • ➕ Add FIXMessage#valueOf(int,int) and FIXMessage#indexOf(int,int) (Kasimir Torri)

    Make it possible to get the index or the value container of the first instance of a field with a specific tag, starting from a specific index.

    • ⚡️ Optimize FIXTimestamps (Jussi Virtanen)

    Decrease the bytecode size of the FIXTimestamps.setDigits method from 36 to 28 bytes, which is within HotSpot's default maximum inline size of 35 bytes. This makes the FIXTimestamps.append method faster.

    • ➕ Add FIXValue#asString(Appendable) (Jussi Virtanen)

    • ➕ Add FIXValue#contentEquals (Jussi Virtanen)

    • ➕ Add FIX Orchestra support to Philadelphia Code Generator (Jussi Virtanen)

    • ➕ Add FIX Latest support (Jussi Virtanen)

    • 👌 Improve FIXMessageParser (Jussi Virtanen)

    Optimize parsing of the BeginString(8), BodyLength(9), and CheckSum(10) values, making message parsing faster.

    • 🛠 Fix EndSeqNo(16) handling (Marcus Harte, Jussi Virtanen)

    Handle the value 0 for the EndSeqNo(16) field in a ResendRequest(2) message correctly. This value represents infinity and corresponds to all subsequent messages after the message referred to by the BeginSeqNo(7) field.

    • 👌 Improve BeginSeqNo(7) handling (Marcus Harte, Jussi Virtanen)

    Respond with a Reject(3) message if the BeginSeqNo(7) value in a ResendRequest(2) message exceeds the current MsgSeqNum(34) value.

    • 👌 Improve NewSeqNo(36) handling (Marcus Harte, Jussi Virtanen)

    Limit the NewSeqNo(36) value in a subsequent SequenceReset(4) message to the current MsgSeqNum(34) if the EndSeqNo(16) value in the preceding ResendRequest(2) message exceeds it.
