Looks like the header file `un.h`, provided by glibc-headers-2.34-60.el9.x86_64, sets the max unix socket address length to 108 characters. ```cpp // /usr/include/sys/un.h /* Structure describing the address of an AF_LOCAL (aka AF_UNIX) socket. */ struct sockaddr_un { __SOCKADDR_COMMON (sun_); char sun_path[108]; /* Path name. */ }; ``` `%t` results in a socket address of `/home/cpsughrue/repos/llvm-project-fork/build/tools/clang/test/ModuleBuildDaemon/Output/handshake.c.tmp/mbd.sock` which is 112 characters. So, in this case, the clang invocation looks to communicate over `mbd.sock` under `/home/cpsughrue/repos/llvm-project-fork/build/tools/clang/test/ModuleBuildDaemon/Output/handshake.c.tmp` but the daemon chops off `.sock` and creates the address `mbd`. I can shorten the file name to `hand.c` or use `-fmodule-build-daemon=handshake-mbd` which places the socket file at `llvm-project/build/tools/clang/test/ModuleBuildDaemon/handshake-mbd/mbd.sock`. Any preference? https://github.com/llvm/llvm-project/pull/67562 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
