Allow a single linefeed-terminated line to be read or written. This is useful for various protocol implementations, including HTTP and pgBackRest's protocol. On read the maximum line size is limited to buffer-size to prevent runaway memory usage in case a linefeed is not found. This seems fine for HTTP but we may need to revisit this decision when implementing the pgBackRest protocol. Another option would be to increase the minimum buffer size (currently 16KB).
pgBackRest
Regression, Unit, & Integration Testing
Introduction
pgBackRest uses Docker to run tests and generate documentation. Docker's light-weight virualization provides the a good balance between proper OS emulation and performance (especially startup)
A Vagrantfile is provided that contains the complete configuration required to run pgBackRest tests and build documentation. If Vagrant is not suitable then the Vagrantfile still contains the configuration steps required to build a test system.
Note that this is not required for normal operation of pgBackRest.
Testing
The easiest way to start testing pgBackRest is with the included Vagrantfile.
Build Vagrant and Logon:
cd test
vagrant up
vagrant ssh
The vagrant up command may take some time as a number of Docker containers must also be built. The vagrant ssh command automatically logs onto the VM.
Run All Tests:
/backrest/test/test.pl
Run Tests for a Specific OS:
/backrest/test/test.pl --vm=co6
Run Tests for a Specific OS and Module:
/backrest/test/test.pl --vm=co6 --module=backup
Run Tests for a Specific OS, Module, and Test:
/backrest/test/test.pl --vm=co6 --module=backup --test=full
Run Tests for a Specific OS, Module, Test, and Run:
/backrest/test/test.pl --vm=co6 --module=backup --test=full --run=1
Run Tests for a Specific OS, Module, Test, and Process Max:
/backrest/test/test.pl --vm=co6 --module=backup --test=full --process-max=4
Note that process-max is only applicable to the synthetic and full tests in the backup module.
Run Tests for a Specific OS, Module, Test, Process Max, and Database Version:
/backrest/test/test.pl --vm=co6 --module=backup --test=full --process-max=4 --pg-version=9.4
Note that pg-version is only applicable to the full test in the backup module.
