Re: [libvirt] [PATCH v3 07/11] livirt: Move URI alias matching to util

As we need to provide support for URI aliases in libvirt-admin as well, URI alias matching needs to be internally visible. Since virConnectOpenResolveURIAlias does have a compatible signature, it could be easily reused by libvirt-admin. This patch moves URI alias matching to util, renaming it accordingly. --- src/libvirt.c | 78 +--------------------------------------- src/libvirt_private.syms | 1 + src/util/viruri.c | 92 ++++++++++++++++++++++++++++++++++++++++++++++++ src/util/viruri.h | 2 ++ 4 files changed, 96 insertions(+), 77 deletions(-) diff --git a/src/util/viruri.c b/src/util/viruri.c index 6166c37..16d27db 100644 --- a/src/util/viruri.c +++ b/src/util/viruri.c @@ -311,3 +315,91 @@ void virURIFree(virURIPtr uri) VIR_FREE(uri); } + + +#define URI_ALIAS_CHARS "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789_-" + +static int +virURIFindAliasMatch(virConfValuePtr value, const char *alias, + char **uri) +{ + virConfValuePtr entry; + size_t alias_len; + + if (value->type != VIR_CONF_LIST) { + virReportError(VIR_ERR_INTERNAL_ERROR, "%s", + _("Expected a list for 'uri_aliases' config parameter")); + return -1; + } + + entry = value->list; + alias_len = strlen(alias); + while (entry) { + char *offset; + size_t safe; + + if (entry->type != VIR_CONF_STRING) { + virReportError(VIR_ERR_CONF_SYNTAX, "%s", + _("Expected a string for 'uri_aliases' config " + "parameter list entry")); + return -1; + } + + if (!(offset = strchr(entry->str, '='))) { + virReportError(VIR_ERR_CONF_SYNTAX, + _("Malformed 'uri_aliases' config entry '%s', " + "expected 'alias=uri://host/path'"), entry->str); + return -1; + } + + safe = strspn(entry->str, URI_ALIAS_CHARS);
