Summary

Adds the libretroshare backend service for the Friend Requests feature:

  • retroshare/rsfriendrequest.h — public RsFriendRequest interface
  • rsserver/p3friendrequest.{h,cc}p3FriendRequest service implementation
  • Registers the new sources in both build systems (src/CMakeLists.txt and src/libretroshare.pro) so the service is compiled and linked.

Why

This is the backend companion to the GUI pull request RetroShare/RetroShare#3216 (gui: add Friend Requests page, closes RetroShare/RetroShare#1794). The GUI page links against rsFriendRequest, so this service must land for that PR to build.

The two PRs are intended to be merged together — the superproject PR's libretroshare submodule pointer references the head of this branch.

Notes

  • Rebased cleanly onto current master; backend sources are additive (no changes to existing files beyond the two build-list entries).

Add rsfriendrequest.h, p3friendrequest.{h,cc} to RS_SOURCES/HEADERS
(CMakeLists.txt) and the qmake HEADERS/SOURCES/PUBLIC_HEADERS lists so
the friend-request backend is actually compiled and linked.

Previously the friend-request backend compiled but was never instantiated
and the global rsFriendRequest pointer (declared extern in
retroshare/rsfriendrequest.h) was defined nowhere, causing an undefined-
reference link error in any consumer (e.g. the GUI Friend Requests page).

- Define RsFriendRequest* rsFriendRequest (mirrors rsPeers in p3peers.cc)
- Instantiate p3FriendRequest in rsinit.cc, assign the global pointer, and
  register it with p3ConfigMgr (friend_requests.cfg) for persistence
- Call onUnknownPeerConnectionAttempt() from AuthSSL::VerifyX509Callback on
  the ISSUER_UNKNOWN (not-a-friend) path so attempts populate the UI

p3Config only declares a no-arg constructor (p3cfgmgr.h), so
': p3Config(CONFIG_TYPE_FRIEND_REQUESTS)' failed to compile (no matching
constructor). RS identifies a config by its filename + RsItem subtype, not
a constructor arg, so drop the bogus argument and the now-dead
CONFIG_TYPE_FRIEND_REQUESTS macro.

Heads-up on a few follow-up commits that make this build and function end-to-end (the backend was previously additive-only):

  • Link fix: define the global RsFriendRequest* rsFriendRequest (was declared extern but defined nowhere → undefined reference in consumers).
  • Compile fix: p3FriendRequest now calls the no-arg p3Config() ctor — p3Config has no type-arg constructor, so the previous p3Config(CONFIG_TYPE_FRIEND_REQUESTS) didn't compile; dropped the unused macro too.
  • Startup wiring: instantiate p3FriendRequest in rsinit.cc, assign the global, and register friend_requests.cfg with p3ConfigMgr.
  • Detection: call onUnknownPeerConnectionAttempt() from AuthSSL::VerifyX509Callback on the ISSUER_UNKNOWN (not-a-friend) path — guarded and thread-safe.
  • Build system: registered the new sources in both CMakeLists.txt and libretroshare.pro.

This is the backend companion to the GUI PR RetroShare/RetroShare#3216 (closes RetroShare/RetroShare#1794); the two are meant to merge together. One thing worth a maintainer's eye: RsFriendRequestItem uses manual serialise/deserialise (p3BanList style) — I couldn't run a full save/load cycle locally, so a check there would be appreciated.

Thx for contributing.

  • Here the serialization system has entirely been re-written instead of using serial_process() and the macro RS_SERIAL_PROCESS which does it all for you. This will remove 50% of your code.
  • p3peermgr already deals with friends, so that would be the place to add a list of pending requests. You'd benefit from the existing serializer there and so on:
    1 - add a new item type to hold the list of friend requests (just like you did)
    2 - update RsPeerConfigSerialiser to deal with it. See for instance how other items serialize automatically using serial_process().
    3 - add the API to rsPeers instead of a new RsFriendRequests

Overall this will be much less code.

(And just in case, don't simply copy-paste these suggestions into an AI without thinking 8-) )

The service did not build. Corrected against the actual API:
- include pqi/p3cfgmgr.h so the p3Config base resolves (this cascade also
  caused the spurious override / "not a direct base" errors)
- fix include path rsserver/p3peermgr.h -> pqi/p3peermgr.h
- RS_PKT_VERSION2 -> RS_PKT_VERSION_SERVICE (the former does not exist)
- RsPeerId/RsPgpId: getId() -> toByteArray(), .init(buf) -> ctor-from-bytes
- call inherited IndicateConfigChanged() without the p3Config:: qualifier
- implement the RsSerializable serial_process() pure virtual (stub) so the
  item is no longer abstract

Persistence is not yet wired (setupSerialiser() returns a bare RsSerialiser),
so entries are in-memory only; serial_process carries a TODO describing how to
finish it via an RsServiceSerializer (cf. p3BanList).
