Support MDTM command

[Ry-Kode]

Hello,

First of all a kind thank you for this great library!

Secondly, I was wondering if you are considering to add support for the MDTM command to get the last modified date of a single file?

Thanks again!

I think that would be a really valuable thing to have. The current implementation is awful (well, actually the specification is awful, the implementation is alright 😀).

Here is the RFC that added MDTM:
https://datatracker.ietf.org/doc/html/rfc3659

I don't think that I will have the spare time to add that command any time soon, but PRs are always welcome 😊

Implementation must be added here:

FEAT:

fineftp-server/fineftp-server/src/ftp_session.cpp

Lines 1081 to 1091 in 550e502

	void FtpSession::handleFtpCommandFEAT(const std::string& /*param*/)
	{
	std::stringstream ss;
	ss << "211- Feature List:\r\n";
	ss << " UTF8\r\n";
	ss << " SIZE\r\n";
	ss << " LANG EN\r\n";
	ss << "211 END\r\n";
	sendRawFtpMessage(ss.str());
	}

MDTM similar to SIZE:

fineftp-server/fineftp-server/src/ftp_session.cpp

Line 495 in 550e502

void FtpSession::handleFtpCommandSIZE(const std::string& param)

Allright Florian, thanks for the response & the tips on how to implement.

I understand your limited availability, I'm facing the same issue :-) Anyway, if I find a spare moment I'll send you a PR and try to add it.
