Unfortunatelly this project does not make nsStandardURL thread safe.

Thread safety is important. Compat and > correctness (talk to Anne!). Performance Thread safety has been on Necko's wish list for a while now, but this project isn't going to fix it. Compatibility with our current implementation is my main concern. Performance might also benefit from this project, as our current implementation does multiple iterations to parse a URI. I expect a slight improvement. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
