    Description

      The mysqlbinlog client program needs to be updated to support GTID.

      Here is a suggested list of things to be done:

      • The --start-position and --stop-position options should be able to take
        GTID positions; or maybe there should be new --start-gtid and --stop-gtid
        options. Like --start-gtid=0-1-100,1-2-200,2-1-1000.
      • A GTID position means the point just after that GTID. So starting from
        GTID 0-1-100 and stopping at GTID 0-1-200, the first GTID output will
        probably be 0-1-101 and the last one 0-1-200. Note that if some domain is
        not specified in the position, it means to start from the begining,
        respectively stop immediately in that domain.
      • Starting and stopping GTID should work both with local files, and with
        --read-from-remote-server. For the latter, there are a couple of extra
        things that need doing in the master-slave protocol, see
        get_master_version_and_clock() in sql/slave.cc.
      • At the end of the dump, put these statements, to reduce the risk of those session variables incorrectly spilling into subsequent statements run in the same session:

           SET session.server_id = @@global.server_id,
               session.gtid_domain_id=@@global.gtid_domain_id;

        Probably some more things will come up during the work, but this looks like a
        reasonable start.

            I think, the first step should be to make a list over all the ways that
            mysqlbinlog currently processes old-style binlog positions (file+offset) in
            any way. And then make suggestions for how mysqlbinlog should do the similar
            task with GTID.

            This is actually a really good starter project for someone to get into working with the GTID code.

            The tasks requires getting some moderate understanding on how GTID works in general, but the actual code that needs to be worked on is fairly isolated and doesn't need to touch a majority of the GTID and replication stuff.

            Some suggestions for getting started with this:

            I would recommend to start by reading the GTID documentation, and
            experimenting with all the relevant features described there, to familiarise
            yourself with it. The main thing is to understand the concept of GTID position
            and binlog order, and the relation to replication domains:

            https://mariadb.com/kb/en/mariadb/global-transaction-id/

            There are also some blog posts:

            http://kristiannielsen.livejournal.com/16826.html
            http://kristiannielsen.livejournal.com/17008.html
            http://kristiannielsen.livejournal.com/17238.html

            And similarly, familiarise yourself with mysqlbinlog and how it would make
            sense for it to be extended to support GTID.

            Then make a detailed proposal for how the user-visible interface of
            mysqlbinlog should be extended, and send it to the list for comments.

            The next step will be to understand the concept of binlog state
            (@@gtid_binlog_state), and how it is used to deal correctly with out-of-order
            GTID sequence numbers in binlogs. This is mostly an internal implementation
            detail, but necessary to be able to correctly identify starting and stopping
            GTID positions in all cases.

            You have logged this issue/idea to four weeks only. Do you recommend GSoC applicants to propose to take on other ideas as well, or elaborate on this one, considering that they might finish this implementation within the estimated time.

            Thanks in advance,

            Why this project was not allocated last year, even though it is being considered for Gsoc from last 3 years.

            Hi,
            I am Mike Reiss a MS Computer Science student and I would love to work on this project during GSoC 2017.I have studied the mysqlbinlog.cc file and experimented with the various options available in the my_options array of the tool. The proposed idea is straight forward to implement: We add the --start-gtid and --stop-gtid options to the array of options then parse the GTID passed to these options to get the GTID sequence number for the binlog. One quick question. Is there any relationship between a GTID sequence number and the argument passed to the --start-position option? that way we need to set the start position to the GTID sequence number. I am still doing more research into the source files and I will love to discuss this more with the mentor. I am having difficulties debugging mysqlbinlog on OS X sierra because it does not support GDB any ideas please?

            mikereiss - a number of gdb options for OS X Sierra are mentioned here http://stackoverflow.com/questions/39702871/gdb-kind-of-doesnt-work-on-macos-sierra . Its essential that you can work an debugger in your development environment and utilising a mentors time to achieve this isn't a productive use of their time especially if they use a different OS. There are plenty of other people/resources that should be able to help you with this.

            @Daniel Black - I'm sorry I should have crafted my question as what is the recommended debugger used by MariaDB developers on OS X ? Thank you for the tip on gdb. Vicențiu on Maria-Developers recommended that I use lldb and it works great for me. Hope its fine with you I continue using lldb.
