commit b5db5f0ab56955b2b89c2ed2364c048a3514b9c3 Author: Robert Middleton <[email protected]> AuthorDate: Thu Mar 24 21:23:14 2022 -0400 LOGCXX-527: mock the clock for tests Mock the clock for unit tests to make them more reliable and configurable. This also cleans up some APR calls to make us less dependent on APR and more on standard C++ features --- src/examples/cpp/delayedloop.cpp | 1 + src/main/cpp/aprinitializer.cpp | 3 +- src/main/cpp/date.cpp | 25 ++++++++-- src/main/cpp/filewatchdog.cpp | 1 - src/main/cpp/hierarchy.cpp | 1 + src/main/cpp/htmllayout.cpp | 4 +- src/main/cpp/loggingevent.cpp | 4 +- src/main/cpp/propertyconfigurator.cpp | 1 + src/main/cpp/timebasedrollingpolicy.cpp | 21 +++----- src/main/include/log4cxx/helpers/aprinitializer.h | 5 +- src/main/include/log4cxx/helpers/date.h | 22 +++++++- .../log4cxx/rolling/timebasedrollingpolicy.h | 1 + src/test/cpp/rolling/timebasedrollingtest.cpp | 58 +++++++++++++++------- 13 files changed, 102 insertions(+), 45 deletions(-) diff --git a/src/examples/cpp/delayedloop.cpp b/src/examples/cpp/delayedloop.cpp index 194473a8..d1768135 100644 --- a/src/examples/cpp/delayedloop.cpp +++ b/src/examples/cpp/delayedloop.cpp @@ -20,6 +20,7 @@ #include <log4cxx/propertyconfigurator.h> #include <apr_general.h> #include <apr_time.h> +#include <apr.h> #include <iostream> #include <log4cxx/stream.h> #include <exception> diff --git a/src/main/cpp/aprinitializer.cpp b/src/main/cpp/aprinitializer.cpp index 0bd91d22..cbaeb77d 100644 --- a/src/main/cpp/aprinitializer.cpp +++ b/src/main/cpp/aprinitializer.cpp @@ -26,6 +26,7 @@ #include <apr_thread_mutex.h> #include <apr_thread_proc.h> #include <log4cxx/helpers/filewatchdog.h> +#include <log4cxx/helpers/date.h> using namespace log4cxx::helpers;
