- Updated exception message in ForkWriteBuffer
- Added test case to tests/queries/0_stateless/02346_into_outfile_and_stdout.sh for calling nextImpl more than once
Implementation:
- Added a new buffer ForkWriteBuffer takes a vector of WriteBuffer and writes data to all of them. It uses the buffer of the first element as its buffer and copies data from first buffer to all the other buffers
Testing:
- Updated tests/queries/0_stateless/02346_into_outfile_and_stdout.sh
Documentation:
- Updated the english documentation for SELECT.. INTO OUTFILE with AND STDOUT.
Implementation:
- Added a bool to ASTQueryWithOutput & patched the usage in ClientBase.
- Added a new buffer TeeWriteBuffer which extends from WriteBufferFromFile (used to write data to the file) and has WriteBufferFromFileDescriptor (used to write data to stdout). The WriteBufferFromFileDescriptor uses the same buffer as TeeWriteBuffer.
- Added a new bool select_into_outfile_and_stdout in ClientBase to enable/disable progress rendering.
Testing:
- Added a test tests/queries/0_stateless/02346_into_outfile_and_stdout.sh
Documentation:
- Updated the english documentation for the new option in SELECT.
