It changes none of the past behaviour, but if you wanted to add an optional directory structure to a config file then simply add this to the default single config file that we ship. /etc/nfsmount.conf: [NFSMount_Global_Options] include=-/etc/nfsmount.conf.d/*.conf The leading minus tells it that it isnt an error if its empty, and it will load all of the fragments it finds in there as well as the existing single file. Apply the same structure to any existing config file that you want to also have a directory for. -Alice diff --git a/support/nfs/conffile.c b/support/nfs/conffile.c index 58c03911..aade50c8 100644 --- a/support/nfs/conffile.c +++ b/support/nfs/conffile.c @@ -53,6 +53,7 @@ #include <libgen.h> #include <sys/file.h> #include <time.h> +#include <glob.h> #include "conffile.h" #include "xlog.h" @@ -690,6 +691,7 @@ conf_parse_line(int trans, char *line, const char *filename, int lineno, char ** if (strcasecmp(line, "include")==0) { /* load and parse subordinate config files */ _Bool optional = false; + glob_t globdata; if (val && *val == '-') { optional = true; @@ -704,33 +706,46 @@ conf_parse_line(int trans, char *line, const char *filename, int lineno, char ** return; } - subconf = conf_readfile(relpath); - if (subconf == NULL) { - if (!optional) - xlog_warn("config error at %s:%d: error loading included config", - filename, lineno); - if (relpath) - free(relpath); - return; - } + if (glob(relpath, GLOB_MARK|GLOB_NOCHECK, NULL, &globdata)) { + xlog_warn("config error at %s:%d: error with matching pattern", filename, lineno); + } else + { + for (size_t g=0; g<globdata.gl_pathc; g++) { + const char * subpath = globdata.gl_pathv[g]; - /* copy the section data so the included file can inherit it - * without accidentally changing it for us */ - if (*section != NULL) { - inc_section = strdup(*section); - if (*subsection != NULL) - inc_subsection = strdup(*subsection); - } + if (subpath[strlen(subpath)-1] == '/') { + continue; + } + subconf = conf_readfile(subpath); + if (subconf == NULL) { + if (!optional) + xlog_warn("config error at %s:%d: error loading included config", + filename, lineno); + if (relpath) + free(relpath); + return; + } + + /* copy the section data so the included file can inherit it + * without accidentally changing it for us */ + if (*section != NULL) { + inc_section = strdup(*section); + if (*subsection != NULL) + inc_subsection = strdup(*subsection); + } - conf_parse(trans, subconf, &inc_section, &inc_subsection, relpath); + conf_parse(trans, subconf, &inc_section, &inc_subsection, relpath); - if (inc_section) - free(inc_section); - if (inc_subsection) - free(inc_subsection); + if (inc_section) + free(inc_section); + if (inc_subsection) + free(inc_subsection); + free(subconf); + } + } if (relpath) free(relpath); - free(subconf); + globfree(&globdata); } else { /* XXX Perhaps should we not ignore errors? */ conf_set(trans, *section, *subsection, line, val, 0, 0);
