* Use O_CLOEXEC / SOCK_CLOEXEC for almost all file descriptors.Richard W.M. Jones2012-03-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The presumption is that all file descriptors should be created with the close-on-exec flag set. The only exception are file descriptors that we want passed through to exec'd subprocesses (mainly pipes and stdin/stdout/stderr). For open calls, we pass O_CLOEXEC as an extra flag, eg: fd = open ("foo", O_RDONLY|O_CLOEXEC); This is a Linux-ism, but using a macro we can easily make it portable. For sockets, similarly: sock = socket (..., SOCK_STREAM|SOCK_CLOEXEC, ...); For accepted sockets, we use the Linux accept4 system call which allows flags to be supplied, but we use the Gnulib 'accept4' module to make this portable. For dup, dup2, we use the Linux dup3 system call, and the Gnulib modules 'dup3' and 'cloexec'.

* daemon: Don't use ../src path to include generator_protocol.hRichard W.M. Jones2010-11-031-1/+1
| | | | | This file is already hard-linked into the current directory, so the relative path is not required.

* generator.ml: use new "Pathname" designationJim Meyering2009-08-131-16/+13
| | | | | | | | | | Nearly every file-related function in daemons/*.c is affected: Remove this pair of statements from each affected do_* function: - NEED_ROOT (return -1); - ABS_PATH (dir, return -1); and change the type of the corresponding parameter to "const char *". * src/generator.ml: Emit NEED_ROOT just once, even when there are two or more Pathname args.
* update all NEED_ROOT usesJim Meyering2009-08-131-1/+1
| | | | | | run this command: git grep -l -w NEED_ROOT|xargs perl -pi -e \ 's/(NEED_ROOT) \((.*?)\)/$1 (return $2)/'
* update all uses of ABS_PATHJim Meyering2009-08-131-1/+1
