From dd9f244f033ba3978d6ee26d9205d29fdd862d7c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Tim-Philipp=20M=C3=BCller?= Date: Tue, 18 Oct 2011 23:19:47 +0100 Subject: [PATCH] registry: add support for GST_REGISTRY_REUSE_PLUGIN_SCANNER=no This will make sure we spawn a new plugin scanner helper for each plugin to be introspected, which helps with making sure we don't load too many shared objects (libs, plugins) at the same time on systems where there is a hard limit like on Android. A better version might re-use the scanner for up to N times, though it's not clear whether that would actually improve things dramatically. https://bugzilla.gnome.org/show_bug.cgi?id=662091 --- gst/gstregistry.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/gst/gstregistry.c b/gst/gstregistry.c index 56107c505b..ddbb78901d 100644 --- a/gst/gstregistry.c +++ b/gst/gstregistry.c @@ -175,6 +175,8 @@ extern GList *_priv_gst_plugin_paths; /* Set to TRUE when the registry cache should be disabled */ gboolean _gst_disable_registry_cache = FALSE; + +static gboolean __registry_reuse_plugin_scanner = TRUE; #endif /* Element signals and args */ @@ -1084,6 +1086,11 @@ gst_registry_scan_plugin_file (GstRegistryScanContext * context, changed = TRUE; } + if (!__registry_reuse_plugin_scanner) { + clear_scan_context (context); + context->helper_state = REGISTRY_SCAN_HELPER_NOT_STARTED; + } + return changed; } @@ -1616,6 +1623,12 @@ ensure_current_registry (GError ** error) } if (do_update) { + const gchar *reuse_env; + + if ((reuse_env = g_getenv ("GST_REGISTRY_REUSE_PLUGIN_SCANNER"))) { + /* do reuse for any value different from "no" */ + __registry_reuse_plugin_scanner = (strcmp (reuse_env, "no") != 0); + } /* now check registry */ GST_DEBUG ("Updating registry cache"); scan_and_update_registry (default_registry, registry_file, TRUE, error);
