OpenSSL Stream Context SSL Session Reuse

[tsmgeek]

Description

We have developed our own FTP client implementation using stream wrappers but we are unable to fully support FTPS on some servers that enforce SSL Session Reuse on the DATA connection.

I have tried to capture the session somehow from the stream context but this is not available.

I can see this has been fixed for the native FTP ext #12851

It would be useful if we could capture this and re-use it for new stream sessions when passing around context.

I am unsure if this already exists.

PHP 8.1/8.3

We have developed our own FTP client implementation using stream wrappers (...)

This is a bit of an aside, but I was wondering what the cause was of creating your own client. Is there a shortcoming in the extension or is it unavailable in your environment, or something else?

This is not currently possible but it should be supported in 8.6. I got actually initial draft PR for that: #20296 .

@bukka Shame so far away

@ndossche we wanted extensive logging of the control channel for debugging, seeing response messages given in commands, the PASV port numbers etc to debug if the other party have setup their firewall incorrectly etc, ie say you called ftp_put, i dont just want true/false, i also wanted to see the actual response causing that state.
We have had this library in place for about over 12 years, it started off a pure implementation of a client using sockets then we moved over to streams and now streamwrappers to support TLS.
Also wanted to have control over the SSL peer verification, certificate suites and also EPASV/EPRT and a few other odd things like HOST/ACCT.
Yes its grown over the years, but its fast and fairly reliable.
