Hello! I'm building an application in which I will have multiple concurrent process reading and writing to a VRT file. The writers are just multiple instances of the same process that create a .vrt off a list of tiffs in a folder. The writer process implement file locking, so I'm sure no two processes will try to write the .vrt at the same time. But the readers (which are gdal_translate calls that use the .vrt as input) don't lock the .vrt so they can be ran at the same time. I can see a race condition happening if gdalbuildvrt overwrites the file when some gdal_translate is opening it. So, if I'm understanding this correctly, the question boils down to: Is the read call that gdal_translate makes when reading a vrt file atomic? And is the write call that gdalbuildvrt makes when writing the file atomic?
Hope this makes sense. Pablo
