From 41e2036eb83204df95a1c3e829bcfd78ee17aaa3 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 10 Oct 2016 21:48:08 +0200 Subject: exit-status: kill is_clean_exit_lsb(), move logic to sysv-generator Let's get rid of is_clean_exit_lsb(), let's move the logic for the special handling of the two LSB exit codes into the sysv-generator by writing out appropriate SuccessExitStatus= lines if the LSB header exists. This is not only semantically more correct, bug also fixes a bug as the code in service.c that chose between is_clean_exit_lsb() and is_clean_exit() based this check on whether a native unit files was available for the unit. However, that check was bogus since a long time, since the SysV generator was introduced and native SysV script support was removed from PID 1, as in that case a unit file always existed. --- src/basic/exit-status.c | 10 ---------- src/basic/exit-status.h | 1 - src/core/service.c | 3 +-- src/systemctl/systemctl.c | 2 +- src/sysv-generator/sysv-generator.c | 8 ++++++++ 5 files changed, 10 insertions(+), 14 deletions(-) diff --git a/src/basic/exit-status.c b/src/basic/exit-status.c index 81c2c6675c..96d4619da6 100644 --- a/src/basic/exit-status.c +++ b/src/basic/exit-status.c @@ -194,16 +194,6 @@ bool is_clean_exit(int code, int status, ExitStatusSet *success_status) { return false; } -bool is_clean_exit_lsb(int code, int status, ExitStatusSet *success_status) { - - if (is_clean_exit(code, status, success_status)) - return true; - - return - code == CLD_EXITED && - IN_SET(status, EXIT_NOTINSTALLED, EXIT_NOTCONFIGURED); -} - void exit_status_set_free(ExitStatusSet *x) { assert(x); diff --git a/src/basic/exit-status.h b/src/basic/exit-status.h index 46cc905865..b3baa50cf4 100644 --- a/src/basic/exit-status.h +++ b/src/basic/exit-status.h @@ -99,7 +99,6 @@ typedef struct ExitStatusSet { const char* exit_status_to_string(int status, ExitStatusLevel level) _const_; bool is_clean_exit(int code, int status, ExitStatusSet *success_status); -bool is_clean_exit_lsb(int code, int status, ExitStatusSet *success_status); void exit_status_set_free(ExitStatusSet *x); bool exit_status_set_is_empty(ExitStatusSet *x); diff --git a/src/core/service.c b/src/core/service.c index 99a70395fc..fc1d353356 100644 --- a/src/core/service.c +++ b/src/core/service.c @@ -2600,8 +2600,7 @@ static void service_sigchld_event(Unit *u, pid_t pid, int code, int status) { assert(s); assert(pid >= 0); - if (UNIT(s)->fragment_path ? is_clean_exit(code, status, &s->success_status) : - is_clean_exit_lsb(code, status, &s->success_status)) + if (is_clean_exit(code, status, &s->success_status)) f = SERVICE_SUCCESS; else if (code == CLD_EXITED) f = SERVICE_FAILURE_EXIT_CODE; diff --git a/src/systemctl/systemctl.c b/src/systemctl/systemctl.c index bb6002e8ef..9c6a475a39 100644 --- a/src/systemctl/systemctl.c +++ b/src/systemctl/systemctl.c @@ -3936,7 +3936,7 @@ static void print_status_info( argv = strv_join(p->argv, " "); printf(" Process: "PID_FMT" %s=%s ", p->pid, p->name, strna(argv)); - good = is_clean_exit_lsb(p->code, p->status, NULL); + good = is_clean_exit(p->code, p->status, NULL); if (!good) { on = ansi_highlight_red(); off = ansi_normal(); diff --git a/src/sysv-generator/sysv-generator.c b/src/sysv-generator/sysv-generator.c index 39821687b9..c2c80175a2 100644 --- a/src/sysv-generator/sysv-generator.c +++ b/src/sysv-generator/sysv-generator.c @@ -25,6 +25,7 @@ #include "alloc-util.h" #include "dirent-util.h" +#include "exit-status.h" #include "fd-util.h" #include "fileio.h" #include "hashmap.h" @@ -199,6 +200,13 @@ static int generate_unit_file(SysvStub *s) { if (s->pid_file) fprintf(f, "PIDFile=%s\n", s->pid_file); + /* Consider two special LSB exit codes a clean exit */ + if (s->has_lsb) + fprintf(f, + "SuccessExitStatus=%i %i\n", + EXIT_NOTINSTALLED, + EXIT_NOTCONFIGURED); + fprintf(f, "ExecStart=%s start\n" "ExecStop=%s stop\n", -- cgit v1.2.3-54-g00ecf
