Jialu Xu 880946158b gen_compile_commands.py: fix path resolve with symlinks in it ... When a path contains relative symbolic links, os.path.abspath() might not follow the symlinks and instead return the absolute path with just the relative paths resolved, resulting in an incorrect path. 1. Say "drivers/hdf/" has some symlinks: # ls -l drivers/hdf/ total 364 drwxrwxr-x 2 ... 4096 ... evdev lrwxrwxrwx 1 ... 44 ... framework -> ../../../../../../drivers/hdf_core/framework -rw-rw-r-- 1 ... 359010 ... hdf_macro_test.h lrwxrwxrwx 1 ... 55 ... inner_api -> ../../../../../../drivers/hdf_core/interfaces/inner_api lrwxrwxrwx 1 ... 53 ... khdf -> ../../../../../../drivers/hdf_core/adapter/khdf/linux -rw-r--r-- 1 ... 74 ... Makefile drwxrwxr-x 3 ... 4096 ... wifi 2. One .cmd file records that: # head -1 ./framework/core/manager/src/.devmgr_service.o.cmd cmd_drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.o := ... \ /path/to/src/drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.c 3. os.path.abspath returns "/path/to/src/framework/core/manager/src/devmgr_service.c", not correct: # ./scripts/clang-tools/gen_compile_commands.py INFO: Could not add line from ./framework/core/manager/src/.devmgr_service.o.cmd: File \ /path/to/src/framework/core/manager/src/devmgr_service.c not found Use os.path.realpath(), which resolves the symlinks and normalizes the paths correctly. # cat compile_commands.json ... { "command": ... "directory": ... "file": "/path/to/bla/drivers/hdf_core/framework/core/manager/src/devmgr_service.c" }, ... Also fix it in parse_arguments().
