2022-10-14Fixed the build on MacOS (and others).Andrew Clayton1-32/+0
@alejandro-colomar reported that the build was broken on MacOS cc -o build/unitd -pipe -fPIC -fvisibility=hidden -O -W -Wall -Wextra -Wno-unused-parameter -Wwrite-strings -fstrict-aliasing -Wstrict-overflow=5 -Wmissing-prototypes -Werror -g \ build/src/nxt_main.o build/libnxt.a \ \ \ -L/usr/local/Cellar/pcre2/10.40/lib -lpcre2-8 Undefined symbols for architecture x86_64: "_nxt_fs_mkdir_parent", referenced from: _nxt_runtime_pid_file_create in libnxt.a(nxt_runtime.o) _nxt_runtime_controller_socket in libnxt.a(nxt_controller.o) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [build/unitd] Error 1 This was due to commit 57fc920 ("Socket: Created control socket & pid file directories."). This happened because this commit introduced the usage of nxt_fs_mkdir_parent() in core code which uses nxt_fs_mkdir(), both of these are defined in src/nxt_fs.c. It turns out however that this file doesn't get built on MacOS (or any system that isn't Linux or that lacks a FreeBSD compatible nmount(2) system call) due to the following In auto/sources we have if [ $NXT_HAVE_ROOTFS = YES ]; then NXT_LIB_SRCS="$NXT_LIB_SRCS src/nxt_fs.c" fi NXT_HAVE_ROOTFS is set in auto/isolation If [ $NXT_HAVE_MOUNT = YES -a $NXT_HAVE_UNMOUNT = YES ]; then NXT_HAVE_ROOTFS=YES cat << END >> $NXT_AUTO_CONFIG_H #ifndef NXT_HAVE_ISOLATION_ROOTFS #define NXT_HAVE_ISOLATION_ROOTFS 1 #endif END fi While we do have a check for a generic umount(2) which is found on MacOS, for mount(2) we currently only check for the Linux mount(2) and FreeBSD nmount(2) system calls. So NXT_HAVE_ROOTFS is set to NO on MacOS and we don't build src/nxt_fs.c This fixes the immediate build issue by taking the mount/umount OS support out of nxt_fs.c into a new nxt_fs_mount.c file which is guarded by the above while we now build nxt_fs.c unconditionally. This should fix the build on any _supported_ system. Reported-by: Alejandro Colomar <alx@nginx.com> Fixes: 57fc920 ("Socket: Created control socket & pid file directories.")

2022-10-03Socket: Created control socket & pid file directories.Andrew Clayton1-0/+1
@alejandro-colomar reported an issue on GitHub whereby Unit would fail to start due to not being able to create the control socket (a Unix Domain Socket) 2022/08/05 20:12:22 [alert] 21613#21613 bind(6, unix:/opt/local/unit/var/run/unit/control.unit.sock.tmp) failed (2: No such file or directory) This could happen if the control socket was set to a directory that doesn't exist. A common place to put the control socket would be under /run/unit, and while /run will exist, /run/unit may well not (/run is/should be cleared on each boot). The pid file would also generally go under /run/unit, though this is created after the control socket, however it could go someplace else so we should also ensure its directory exists. This commit will try to create the pid file and control sockets parent directory. In some cases the user will need to ensure that the rest of the path already exists. This adds a new nxt_fs_mkdir_parent() function that given a full path to a file (or directory), strips the last component off before passing the remaining directory path to nxt_fs_mkdir().

2020-08-25Isolation: added "automount" option.Tiago Natel de Moura1-5/+6
Now it's possible to disable default bind mounts of languages by setting: { "isolation": { "automount": { "language_deps": false } } } In this case, the user is responsible to provide a "rootfs" containing the language libraries and required files for the application.
