How do I traverse a directory in Mozilla Firefox 4.0 and beyond? -

used this:

class="lang-js prettyprint-override">// firefox 3.6 , before; mozilla 1.9.2 , before var ext = this.cc["@mozilla.org/extensions/manager;1"] .getservice(this.ci.nsiextensionmanager) .getinstalllocation(id) .getitemlocation(id); // list xml files in installation folder: var entries = ext.directoryentries; var files = []; while(entries.hasmoreelements()) { )

how ext variable now? have gotten far following:

class="lang-js prettyprint-override">components.utils.import("resource://gre/modules/addonmanager.jsm"); addonmanager.getaddonbyid(id, function(addon) { ext = addon.getresourceuri(""); }

but not sure how directory info traverse it...

there might not directory traverse - starting firefox 4 extensions no longer unpacked when install them, resource uri point xpi file (via jar: protocol scheme). again, in cases extension unpacked upon installation, file:/// uri. should (untested):

class="lang-js prettyprint-override">var uri = addon.getresourceuri(""); if (uri instanceof components.interfaces.nsijaruri) { var xpifile = uri.jarfile.queryinterface(components.interfaces.nsifileurl).file; var reader = components.classes["@mozilla.org/libjar/zip-reader;1"] .createinstance(components.interfaces.nsizipreader); reader.init(xpifile); var enumerator = reader.findentries(null); while (enumerator.hasmoreelements()) { var entry = enumerator.getnext().queryinterface(components.interfaces.nsizipentry); alert(entry.name); } reader.close(); } else if (uri instanceof components.interfaces.nsifileurl) { var dir = uri.file; var enumerator = dir.directoryentries; while (enumerator.hasmoreelements()) { var entry = enumerator.getnext().queryinterface(components.interfaces.nsifile); alert(entry.path); } } else throw new error("unexpected install location");

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
