The function pointer casting used when creating drivers made changing interfaces difficult and led to slightly divergent driver implementations. Unit testing caught production-level errors but there were a lot of small issues and the process was harder than it should have been. Use void pointers instead so that no casts are required. Introduce the THIS_VOID and THIS() macros to make dealing with void pointers a little safer. Since we don't want to expose void pointers in header files, driver functions have been removed from the headers and the various driver objects return their interface type. This cuts down on accessor methods and the vast majority of those functions were not being used. Move functions that are still required to .intern.h. Remove the special "C" crypto functions that were used in libc and instead use the standard interface.
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: 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: process-max is only applicable to the
syntheticandfulltests in thebackupmodule.
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: pg-version is only applicable to the
fulltest in thebackupmodule.
