Module: sip-router Branch: andrei/shm_early_init Commit: 647cc9832560590adc6e20685c2d53350a932fb2 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=647cc98… Author: Andrei Pelinescu-Onciul &lt;andrei(a)iptel.org&gt; Committer: Andrei Pelinescu-Onciul &lt;andrei(a)iptel.org&gt; Date: Sun Jan 10 13:10:43 2010 +0100 core: shm mem size can now be set in the config script shm mem size can now be set in the cfg script using shm=size_in_mb, shm_mem=size_in_mb or shm_mem_size=size_in_mb. It must be set prior to any modparam or route block. Specifying the memory size on the command line (-m size_in_mb) will override the size from the config file. --- cfg.lex | 4 ++++ cfg.y | 12 +++++++++++- main.c | 2 +- 3 files changed, 16 insertions(+), 2 deletions(-) diff --git a/cfg.lex b/cfg.lex index 61e694e..0f7deec 100644 --- a/cfg.lex +++ b/cfg.lex @@ -80,6 +80,7 @@ * 2009-03-10 added SET_USERPHONE action (Miklos) * 2009-04-24 add strlen, strempty and defined operators (andrei) * 2009-03-07 RETCODE, it's now a core pvar (andrei) + * 2010-01-10 added SHM_MEM_SZ (andrei) */ @@ -430,6 +431,7 @@ ADVERTISED_ADDRESS "advertised_address" ADVERTISED_PORT "advertised_port" DISABLE_CORE "disable_core_dump" OPEN_FD_LIMIT "open_files_limit" +SHM_MEM_SZ "shm"|"shm_mem"|"shm_mem_size" SHM_FORCE_ALLOC "shm_force_alloc" MLOCK_PAGES "mlock_pages" REAL_TIME "real_time" @@ -818,6 +820,8 @@ EAT_ABLE [\ \t\b\r] return DISABLE_CORE; } <INITIAL>{OPEN_FD_LIMIT} { count(); yylval.strval=yytext; return OPEN_FD_LIMIT; } +<INITIAL>{SHM_MEM_SZ} { count(); yylval.strval=yytext; + return SHM_MEM_SZ; } <INITIAL>{SHM_FORCE_ALLOC} { count(); yylval.strval=yytext; return SHM_FORCE_ALLOC; } <INITIAL>{MLOCK_PAGES} { count(); yylval.strval=yytext; diff --git a/cfg.y b/cfg.y index ac07fc1..9a71817 100644 --- a/cfg.y +++ b/cfg.y @@ -96,7 +96,8 @@ * 2009-01-26 case/switch() support (andrei) * 2009-03-10 added SET_USERPHONE action (Miklos) * 2009-05-04 switched if to rval_expr (andrei) - * 2010-01-10 init shm on first mod_param or route block (andrei) + * 2010-01-10 init shm on first mod_param or route block; + * added SHM_MEM_SZ (andrei) */ %{ @@ -494,6 +495,7 @@ extern char *finame; %token ADVERTISED_PORT %token DISABLE_CORE %token OPEN_FD_LIMIT +%token SHM_MEM_SZ %token SHM_FORCE_ALLOC %token MLOCK_PAGES %token REAL_TIME @@ -1463,6 +1465,14 @@ assign_stm: | DISABLE_CORE EQUAL error { yyerror("boolean value expected"); } | OPEN_FD_LIMIT EQUAL NUMBER { open_files_limit=$3; } | OPEN_FD_LIMIT EQUAL error { yyerror("number expected"); } + | SHM_MEM_SZ EQUAL NUMBER { + if (shm_initialized()) + yyerror("shm/shm_mem_size must be before any modparam or the" + " route blocks"); + else if (shm_mem_size == 0) + shm_mem_size=$3 * 1024 * 1024; + } + | SHM_MEM_SZ EQUAL error { yyerror("number expected"); } | SHM_FORCE_ALLOC EQUAL NUMBER { if (shm_initialized()) yyerror("shm_force_alloc must be before any modparam or the" diff --git a/main.c b/main.c index 31a4b65..8d0f7e5 100644 --- a/main.c +++ b/main.c @@ -469,7 +469,7 @@ int cfg_warnings=0; /* shared memory (in MB) */ -unsigned long shm_mem_size=SHM_MEM_SIZE * 1024 * 1024; +unsigned long shm_mem_size=0; /* export command-line to anywhere else */ int my_argc;
