|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit removes support for: * ram_file:open/2 with deprecated file modes (it is now equivalent to raw_file_io:open/2) * ram_file:set_file/2 and ram_file:get_file_close/1 which are private and not used anywhere in Erlang/OTP * ram_file:uuencode/1 and ram_file:uudecode/2 which which are private and not used anywhere in Erlang/OTP Note that ram_file:get_size/1 also fits this criteria but it was kept because there is some usage in the wild.
* | [erts|inet] Casting warnings on windowsMicael Karlberg2020-06-151-204/+245
| | | | | | | | | | | | | | | | | | The debug macro calls used, on Windows, the wrong casting type and format string for the port type. Use '%p' as format string for pointer, no casting needed (since the ErlDrvPort is actually a pointer). OTP-16715

Commit 011954e851d421b882b0b4eaeda04cfc2895d70a changed SOCKLEN_T from int to size_t which is not correct on Windows. Kept size_t fallback on non-Windows with a compile #warning, not sure if this is ever needed/correct.

* | | [erts] Tweaked the config and usage of SCTP for NetBSDMicael Karlberg2020-03-041-7/+9
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | On NetBSD the type sctp_assoc_value does not exist. Its used normally when setting, for instance, the option SCTP_DELAYED_ACK_TIME. This option *does* exist on NetBSD, but it can only be used to set the "default value" (which on Linux is done by setting assoc_id (in assoc_value) to 0). The way to "properly" handle this on NetBSD would be to accept this option (for inet:[setopts/getopts]), but verify that the assoc id is zero (0). For now we simply test for the type, and if it does not exist, we do not allow set/get of this option.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Propagate unmodified header fields in the previously Reserved and undefined 4th element of the http_header tuple. *Why do we need this new feature?* While Section 4.2 of RFC 2616 for HTTP/1.1 states that Field names are case-insensitive, some non-compliant web services may rely on peculiar casing of Field names. Such web-services cannot be accessed through a Proxy-server, that is implemented in Erlang/OTP, certainly not over HTTPS. Despite the RFC, even the IANA lists a number of permanently registered headers in all-caps or mixed-cased format, e.g.: ALPN, HTTP2-Settings, WWW-Authenticate, etc. This leads to confusion and to service implementations, that only accept headers formatted the same way. A production issue was experienced using the common, drafted, but not yet standard header: DNT. There are a number of HTTP servers implemented in Erlang that could be used in a Proxy implementation. However, there is none that would respect header-casing. * cowboy, httpd - their header parser lower-cases the fields * yaws - emulators' internal HTTP header parsing via ssl/inet * mochiweb, elli - both use erlang:decode_packet/3 As a side note: An HTTPS-Proxy requires CONNECT method support. Therefor cowboy is not a real option despite its popularity. With this proposal yaws, mochiweb and elli could all be patched to respect casing of header fields and propagate the original header format to the application level modules. The DNT header issue was experienced using a patched mochiweb. *Risks or uncertain artifacts?* These changes are minimalistic and backward compatible, given application developers respected the documentation. All above mentioned http servers do so, they ignore the 4th element of http_header tuple. It was verified in the master branches of the project repositories. *How did you solve it?* The proposal is that packet_parser.c should also propagate unmodified fields to both inet_drv.c and erl_bif_port.c, where these would be put in the 4th place of the http_header tuple. Its recognised, that this element was Reserved for future and/or internal use. Hopefully you'd agree, that sending the original header fields is a productive use-case to free up the reservation. Adding a new httph_cs option, cs for case-sensitive, was also considered. I got the impression thought, that these these packet decoders exit for compatibility reasons only and the OTP-Team is not keen on adding new options.

| | * erts: Add yield via timeout to inet read_packetLukas Larsson2019-02-181-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea here is that the timeout of 0 will work like a yield so that that we don't starve other ports/processes, but it is faster than the select trigger. We don't deselect on the socket because it does not matter if it is triggered laster or not as we'll just get an EAGAIN. Doing this also circumvents the fact that no select is done on active true style sockets until all I/O has been handled. So in a system with a lot of active true style I/O this will could be very benificial.
