# Always try to copy the files to the bin directory after every build and deliberatly ignore
|
|
# copy errors, usually the error is because a running process has locked the file.
|
|
#
|
|
# It is useful to copy every time because the copy may have failed last time due to the file
|
|
# being in use, and we'll usually want to try again (after killing the process).
|
|
#
|
|
# Yes, this looks like a ridiculous thing to do, but it really is necessary to
|
|
# use a Python script to copy files on Windows. Why? Two reasons:
|
|
#
|
|
# 1. Windows file locks (on running processes) creates a very painful development
|
|
# experience; you can't overwrite the binary you're running it.
|
|
# Why not just stop the process? Windows services are an abject PITA to manage,
|
|
# and we don't always care about overwriting all binaries.
|
|
#
|
|
# 2. The Windows copy command is limited and gives vague/misleading errors.
|
|
# The CMake copy command also has similar shortfalls.
|
|
#
|
|
# Patches welcome! :)
