|
|
*
|
|
* OGR C API spy.
|
|
*
|
|
* If GDAL is compiled with OGRAPISPY_ENABLED defined (which is the case for a
|
|
* DEBUG build), a mechanism to trace calls to the OGR *C* API is available
|
|
* (calls to the C++ API will not be traced)
|
|
*
|
|
* Provided there is compile-time support, the mechanism must also be enabled at
|
|
* runtime by setting the OGR_API_SPY_FILE configuration option
|
|
* to a file where the calls to the OGR C API will be dumped (stdout and stderr
|
|
* are recognized as special strings to name the standard output and error
|
|
* files). The traced calls are outputted as a OGR Python script.
|
|
*
|
|
* Only calls that may have side-effects to the behavior of drivers are traced.
|
|
*
|
|
* If a file-based datasource is open in update mode, a snapshot of its initial
|
|
* state is stored in a 'snapshot' directory, and then a copy of it is made as
|
|
* the working datasource. That way, the generated script can be executed in a
|
|
* reproducible way. The path for snapshots is the current working directory by
|
|
* default, and can be changed by setting the OGR_API_SPY_SNAPSHOT_PATH
|
|
* configuration option. If it is set to NO, the snapshot feature will be
|
|
* disabled. The reliability of snapshoting relies on if the dataset correctly
|
|
* implements GetFileList() (for multi-file datasources)
|
|
*
|
|
* @since GDAL 2.0
