All functions also ensure that the message ends with "\n", meaning that you do not need to add it into the message, but if you do, an extra "\n" will not be added. All functions ensure that the string is written in a single write() call, thus if two processes output to the same terminal or file, messages don't get intermingled. Ordinarily, messages go to the stderr. By setting global variable "logmode" to LOGMODE_SYSLOG or LOGMODE_NONE, they can be sent to syslog or be suppressed. Standard setting is LOGMODE_STDIO. LOGMODE_STDIO + LOGMODE_SYSLOG works too. Usually it is set by main() as needed, and then you can fearlessly use [p]error_msg[_and_die]() and be sure that message goes to the right place. +enum { + LOGMODE_NONE = 0, + LOGMODE_STDIO = (1 << 0), + LOGMODE_SYSLOG = (1 << 1), + LOGMODE_BOTH = LOGMODE_SYSLOG + LOGMODE_STDIO, +}; +extern int logmode; Exit code of xxx_and_die variants is controlled by the global variable +extern int xfunc_error_retval; By default it is = 1. Logging infrastructure uses a few other functions, which I find useful on their own, and since I discussed them with Zdenek and he thinks that they may be useful too, they are included in the patch also. The first group is "malloc or die" group: +void* malloc_or_warn(size_t size); +void* xmalloc(size_t size); +void* xrealloc(void *ptr, size_t size); +void* xzalloc(size_t size); +char* xstrdup(const char *s); +char* xstrndup(const char *s, int n); They are basically versions of malloc etc which exit on failure. The next group are simple I/O wrappers: +extern ssize_t safe_read(int fd, void *buf, size_t count); +extern ssize_t full_read(int fd, void *buf, size_t count); +extern void xread(int fd, void *buf, size_t count); +extern ssize_t safe_write(int fd, const void *buf, size_t count); +extern ssize_t full_write(int fd, const void *buf, size_t count); safe_xxx deal with the fact that read and write operations may "fail" with EINTR and in many cases we want to just repeat the operation. full_xxx deal with the fact that read and write are not guaranteed to read or write exact amount, they may to transfer less bytes. In this case we need to loop. The next group are the "x functions": +extern void xwrite(int fd, const void *buf, size_t count); +extern void xwrite_str(int fd, const char *str); +void xpipe(int filedes[2]); +void xdup2(int from, int to); +off_t xlseek(int fd, off_t offset, int whence); +void xsetenv(const char *key, const char *value); +int xsocket(int domain, int type, int protocol); +void xbind(int sockfd, struct sockaddr *my_addr, socklen_t addrlen); +void xlisten(int s, int backlog); +ssize_t xsendto(int s, const void *buf, size_t len, const struct sockaddr *to, socklen_t tolen); +void xstat(const char *name, struct stat *stat_buf); +void xmove_fd(int from, int to); +char* xasprintf(const char *format, ...); They are similar to xmalloc in a sense that they exit on the failure. Most of them closely resemble corresponding libc functions. xmove_fd() is a wrapper for typical idiom "if (fd1!=fd2) dup2(fd1,fd2)", with error checking on dup2 failure added. xasprintf() is a "strcat on steroids". It's a printf-like function which returns a malloced string. In my experience, it is surprisingly useful: it makes complex concatenations easy in C. All these functions are declared in a new header, inc/abrtlib.h. It also contains a list of #includes: +#include <ctype.h> +#include <dirent.h> +#include <errno.h> +#include <fcntl.h> +#include <inttypes.h> +#include <setjmp.h> +#include <signal.h> +#include <stdio.h> +#include <stdlib.h> +#include <stdarg.h> +#include <stddef.h> +#include <string.h> +#include <sys/poll.h> +#include <sys/mman.h> +#include <sys/socket.h> +#include <sys/stat.h> +#include <sys/time.h> +#include <sys/types.h> +#include <sys/wait.h> +#include <termios.h> +#include <time.h> +#include <unistd.h> +/* Try to pull in PATH_MAX */ +#include <limits.h> +#include <sys/param.h> +#ifndef PATH_MAX +# define PATH_MAX 256 +#endif +#include <pwd.h> +#include <grp.h> The rationale to do so is that these headers are pretty standard, and by having them included in this one file, we won't need to add #includes into many .c[pp] files later. The slowdown from gcc parsing these headers even if they are not needed is not worth spending time on optimizing out. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | Signals are asynchronous. It is unsafe to perform such complex operations in a signal handler. I changed signal handler to just set a flag, and added an event source which returns an event when this variable is set. The action is to stop event loop. Execution then falls through to program exit. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
