From f5bebbbb28dc7a149a891f0f1e112fb50bb72664 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 30 Sep 2014 13:59:30 +0200 Subject: util: Emancipate id_wellformed() from QemuOpts IDs have long spread beyond QemuOpts: not everything with an ID necessarily goes through QemuOpts. Commit 9aebf3b is about such a case: block layer names are meant to be well-formed IDs, but some of them don't go through QemuOpts, and thus weren't checked. The commit fixed that the straightforward way: rename the internal QemuOpts helper id_wellformed() to qemu_opts_id_wellformed() and give it external linkage. Instead of using it directly in block.c, the commit adds wrapper bdrv_is_valid_name(), probably to hide the connection to QemuOpts. Go one logical step further: emancipate IDs from QemuOpts. Rename the function back to id_wellformed(), and put it in another file. While there, clean up its value to bool. Peel off the bdrv_is_valid_name() wrapper. [Replaced stray return 0 with return false to match bool returns used elsewhere in id_wellformed(). --Stefan] Signed-off-by: Markus Armbruster Signed-off-by: Stefan Hajnoczi --- util/qemu-option.c | 17 +---------------- 1 file changed, 1 insertion(+), 16 deletions(-) (limited to 'util/qemu-option.c') diff --git a/util/qemu-option.c b/util/qemu-option.c index 0cf9960fc5..5d106959ca 100644 --- a/util/qemu-option.c +++ b/util/qemu-option.c @@ -641,28 +641,13 @@ QemuOpts *qemu_opts_find(QemuOptsList *list, const char *id) return NULL; } -int qemu_opts_id_wellformed(const char *id) -{ - int i; - - if (!qemu_isalpha(id[0])) { - return 0; - } - for (i = 1; id[i]; i++) { - if (!qemu_isalnum(id[i]) && !strchr("-._", id[i])) { - return 0; - } - } - return 1; -} - QemuOpts *qemu_opts_create(QemuOptsList *list, const char *id, int fail_if_exists, Error **errp) { QemuOpts *opts = NULL; if (id) { - if (!qemu_opts_id_wellformed(id)) { + if (!id_wellformed(id)) { error_set(errp,QERR_INVALID_PARAMETER_VALUE, "id", "an identifier"); #if 0 /* conversion from qerror_report() to error_set() broke this: */ error_printf_unless_qmp("Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.\n"); -- cgit v1.2.3-55-g7522
