d309a85b51 PostgreSQL 11 Beta 1 support. 2018-06-05 08:59:17 -04:00

2f6017511f Split log levels into separate header file. 
Many modules that use debug.h do not need to do logging so this reduces dependencies for those modules.

52bc073234 Add stack trace macros to all functions. 
Low-level functions only include stack trace in test builds while higher-level functions ship with stack trace built-in. Stack traces include all parameters passed to the function but production builds only create the parameter list when the log level is set high enough, i.e. debug or trace depending on the function.

4d6a51ac47 Add HARNESS_FORK for tests that require fork(). 
A standard pattern for tests makes fork() easier to use and should help prevent some common mistakes.

6a40c916d4 Add repo-s3-token option to allow temporary credentials tokens to be configured. 
pgBackRest currently has no way to request new credentials so the entire command (e.g. backup, restore) must complete before the credentials expire.

27aa5f756e Add support for additional pgBackRest configuration files. 
Configuration files are loaded from the directory specified by the --config-include-path option.

2a4ff2f904 Split cfgLoad() into multiple functions to make testing easier. 
Mainly this helps with unit tests that need to do log expect testing. Add harnessCfgLoad() test function, which allows a new config to be loaded for unit testing without resetting log functions, opening a log file, or taking locks.
 2018-04-13 16:05:52 -04:00
David Steele
f0250dab4b Move async forking and more error handling to C. 
The Perl process was exiting directly when called but that interfered with proper locking for the forked async process. Now Perl returns results to the C process which handles all errors, including signals.
 2018-04-12 20:42:26 -04:00
David Steele
6fd0c3dcaa Improved lock implementation written in C. 
Now only two types of locks can be taken: archive and backup. Most commands use one or the other but the stanza-* commands acquire both locks. This provides better protection than the old command-based locking scheme.
 2018-04-11 09:36:12 -04:00
David Steele
4744eb9387 Add storagePathRemove() and use it in the Perl Posix driver. 
This implementation should be faster because it does not stat each file.  It simply assumes that most directory entries are files so attempts an unlink() first.  If the entry is reported by error codes to be a directory then it attempts an rmdir().

b77b425096 Allow -DDEBUG_UNIT to be suppressed to test how debug macros behave. 2018-04-07 19:44:00 -04:00
David Steele
82751b3b51 Split debug and assert code into separate headers. 
Assert can be used earlier because it only depends on the error-handler and not logging.
 2018-04-07 13:12:35 -04:00
David Steele
f3b56cf8f3 Allow MemContext objects to be copied to a new parent. 
This makes it easier to create objects and then copy them to another context when they are complete without having to worry about freeing them on error. Update List, StringList, and Buffer to allow moves. Update Ini and Storage to take advantage of moves.
 2018-04-06 17:04:52 -04:00

b9f636cab4 Cleanup C types.

93fdb98d15 Storage object improvements. 
* Convert all functions to variadic functions.
* Enforce read-only storage.
* Add storageLocalWrite() helper function. Add storageExists(), storagePathCreate(), storageRemove(), and storageStat().
* Add StorageFile object and storageOpenRead()/storageOpenWrite().

9001b9b957 Replace THROW_ON_SYS_ERROR() with THROW_SYS_ERROR().

b234f43c9d Refactor usec to msec in common/time.c. 
The implementation provides usec resolution but this is not needed in practice and it makes the interface more complicated due to the extra zeros.

f4ed36d128 Add switch() to lcov branch exclusions. 
lcov requires default to show complete coverage but --Wswitch-enum enforces all enum values be present so no default is needed.

Add documentation for each branch exclusion.
 2018-03-20 10:17:53 -04:00
David Steele
d34142dee8 Update lcov settings. 
Mark any coverage less that 100% as yellow, less that 90% as red.

Add comments to config file and make genhtml use it as well as lcov.
 2018-03-20 09:47:51 -04:00
David Steele
07f38f584a Use lcov for C unit test coverage reporting. 
Switch from Devel::Cover because it would not report on branch coverage for reports converted from gcov.

Branch coverage is not complete, so for the time being errors will only be generated when statement coverage is not complete. Coverage of unit tests is not displayed in the report unless they are incomplete for either statement or branch coverage.

2c1687721e Fix issue where specifying log-level-stderr > warn would cause a local/remote process to error on exit due to output found on stderr when none was expected. 
The max value for a local/remote process is now error since there's no reason for these processes to emit warnings.

8a1ce42c30 Immediately error when a secure option (e.g. repo1-s3-key) is passed on the command line. 
Since pgBackRest would not pass secure options on to sub-processes an obscure error was thrown. The new error is much clearer and provides hints about how to fix the problem.

Update command documentation to omit secure options that cannot be specified on the command-line.

03f1082e86 Improve logging. 
Move command begin to C except when it must be called after another command in Perl (e.g. expire after backup). Command begin logs correctly for complex data types like hash and list. Specify which commands will log to file immediately and set the default log level for log messages that are common to all commands. File logging is initiated from C.
