I'll try to contact he and hope to he remembers; This should be the most dedicated matter, so I would not like to do any proposals involving this without knowing why remove this API specific classes would be an error.
I also think we can get rid of the Executable concept which currently must be a std::string anyway.
I agree. In future would not be hard re-enable this concept if needed, differently from the number 1.
Here the problem is that on Windows only named pipes support asynchronous I/O. [..] If we distinguish between anonymous and named pipes anyway we could provide appropriate classes which could be used by developers elsewhere. [...]. If we want to support asynchronous I/O on Windows we have to think about all of this.
I don't have a final idea about this yet, but I'm quite sure we can bypass it. One way to do this, would define two helpers create_named_pipe and create_anonymous_pipe. In the POSIX asynchronous implementation it can receive any pipe, and in Windows only named_pipes. There is the need of other helper, create_async_pipe, to create in windows named and in POSIX unnamed, this closing all combinations. A little tricky, but multiplataform and the user keep the control about the name of his pipes.
The unit tests of Ilya's Boost.Process drafts (the one in the vault) are pretty good because everything works automatically if I remember correctly [...]
I'm not sure what issues I was talking about. Sorry for the noise. -- Felipe de Oliveira Tanus E-mail: fotanus@gmail.com Blog: http://www.itlife.com.br Site: http://www.inf.ufrgs.br/~fotanus/ ----- "All we have to decide is what to do with the time that is given us." - Gandalf
