today,i'll using the open source tool named "binlog2sql" which is release by danfengchao to do some flashback test.
here's the github address:https://github.com/danfengcao/binlog2sql
according to the readme.md doc,using "git" command to download it at the beginning:
1 ns-notepc399+jujun@ns-notepc399 MINGW64 /d/vagrant 2 $ git clone https://github.com/danfengcao/binlog2sql.git && cd binlog2sql 3 Cloning into 'binlog2sql'... 4 remote: Counting objects: 294, done. 5 remote: Total 294 (delta 0), reused 0 (delta 0), pack-reused 294 6 Receiving objects: 100% (294/294), 142.05 KiB | 108.00 KiB/s, done. 7 Resolving deltas: 100% (152/152), done. 8 ns-notepc399+jujun@ns-notepc399 MINGW64 /d/vagrant/binlog2sql (master)
secondly,"pip" command need to be installed,which can be downloaded on the official
website:https://pypi.org/project/pip/
the latest version is 10.0.1 now,i choose the tar package to download.

the binlog2sql tool has been installed,let's begin the test now:

throught the evidence above,i'm afaid the binlog2sql tool didn't recognize the right path of the binlog files and cast an exception at all.Am i right?

unfortunately it still doesn't work,i'm confused and have no idea now,maybe i'll test it again text time.Let's see then.
Summury:
- binlog2sql is coded by python,in order to use it you need to install python and relevant packages.
- some parameter such as "binlog_format=row","binlog_row_image=full" etc. in MySQL Server should be satisfied with.
- some privileges such as "super"/"replication client","replication slave" etc. in MySQL Server should be satisfied with too.
- it seems more inconvenient rather than the MyFlash tool does.
