// Interesting static constructor bug: |
| 54 |
// |
| 55 |
// The RandomDirection2dMobilityModel declares a RandomVariableDefaultValue |
| 56 |
// g_speedVariable. This variable is initialized in the |
| 57 |
// static_initialization_and_destruction_0 function as expected. This causes |
| 58 |
// RandomVariableDefaultValue::Parse () to be called which calls NS_LOG_X |
| 59 |
// functions. The macro calls LogComponent::IsEnabled () which calls |
| 60 |
// LogComponentEnableEnvVar (). The following variable called isFirstLog |
| 61 |
// is set after the first call to prevent the environment variable from |
| 62 |
// actually being parsed on every log call. |
| 63 |
// |
| 64 |
// When the RandomDirection2dMobilityModel static constructor is run, other |
| 65 |
// log components may not have had their static constructors run yet. It is |
| 66 |
// in those other static constructors that their log components are added to |
| 67 |
// the list of log components. |
| 68 |
// |
| 69 |
// The end result is that if any code calls an NS_LOG_X function during its |
| 70 |
// static constructor, the environment variable check is "locked out" for |
| 71 |
// any log component declarations (in different compilation units) that have |
| 72 |
// not yet been executed. |
| 73 |
// |
| 74 |
// So, the choice seems to be to either 1) parse the environment variables |
| 75 |
// at every log call; or 2) make LogComponentEnableEnvVar explicitly called |
| 76 |
// after all other static constructors are called. This means in main (). |
| 77 |
// The former choice seems the only reasonable way out if we care remotely |
| 78 |
// about performance in logging. |
| 79 |
// |
| 80 |
// I made LogComponentEnableEnvVar a public API that you need to call in |
| 81 |
// main () if you want to use environment variables to drive the log output. |
