发布 SPW 后我才知道侧键可以在一些软件前进后退，因为我从来没用过 说来搞笑，大一的时候买了个 G102，一直用，最开始发现可以自定义 然后我的侧键一直是点击后可以输出文本： #include<stdio.h> int main() { return 0; } （当时初学 C 语言，经常写题目要打这些哈哈哈哈哈）

TelegramMessenger/tgcalls/experimental • 616810f • 38 files, +38/-0 build: add #include <cstdint> for GCC 15 compatibility TelegramMessenger/tgcalls/experimental • 24fd51b • 7 files, +2218/-19 feat: SCTP signaling improvements for reliable connection establishment Add writable gate for role-based SCTP handshake ordering: caller (isOutgoing=true) starts writable and sends INIT immediately; callee starts not-writable and defers Connect() until first received packet triggers setWritable(true). Implement CustomDcSctpSocket to fix WebRTC's missing timer backoff cap on t1_init and t1_cookie handshake timers. Without this, simultaneous-open under packet loss causes 20+ second stalls due to unlimited exponential backoff (1s, 2s, 4s, 8s...). With the fix: 400ms init, 750ms max backoff, yielding ~18 attempts in 15s and 100% success at 30% loss. Timer values are configurable via JSON custom parameters: - network_sctp_t1_init_ms, network_sctp_t1_cookie_ms, network_sctp_max_backoff_ms Squashed from: - feat: add SCTP writable gate for role-based handshake ordering - chore: whitespace cleanup in NativeNetworkingImpl - fix: CustomDcSctpSocket with t1 timer backoff cap for signaling SCTP TelegramMessenger/tgcalls/experimental • 212a874 • 1 files, +5/-0 fix: use-after-free in InstanceV2ReferenceImpl::writeStateLogRecords() writeStateLogRecords() captured a raw Call* pointer on the media thread and posted it to the worker thread. If stop() called _peerConnection->Close() (which destroys Call) between the post and worker thread execution, the worker thread would dereference a dangling pointer. WebRTC's call_ptr_ is Call* const and never nulled after Close(), so the existing null check didn't catch this. Fix: add _isStopped atomic flag, set before Close() in stop(), checked in the worker thread lambda before accessing call. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]> #tgcalls
