This is an automated email from the git hooks/post-receive script. x2go pushed a commit to branch upstream/28.5.0 in repository pale-moon. commit 3c02dbad946487a83783a1923463a1ebb96aae19 Author: wolfbeast <mcwerewolf@wolfbeast.com> Date: Fri Mar 22 12:44:26 2019 +0100 Clean up nsOSHelperAppService. About time we stopped looking at Netscape 4.x entries in the registry ;) Also, assume the application association API is present in Windows and use that instead of reading from the registry directly. --- uriloader/exthandler/win/nsOSHelperAppService.cpp | 192 +++++++--------------- 1 file changed, 57 insertions(+), 135 deletions(-) diff --git a/uriloader/exthandler/win/nsOSHelperAppService.cpp b/uriloader/exthandler/win/nsOSHelperAppService.cpp index f01f3b4..48b6f17 100644 --- a/uriloader/exthandler/win/nsOSHelperAppService.cpp +++ b/uriloader/exthandler/win/nsOSHelperAppService.cpp @@ -29,8 +29,6 @@ #define LOG(args) MOZ_LOG(mLog, mozilla::LogLevel::Debug, args) // helper methods: forward declarations... -static nsresult GetExtensionFrom4xRegistryInfo(const nsACString& aMimeType, - nsString& aFileExtension); static nsresult GetExtensionFromWindowsMimeDatabase(const nsACString& aMimeType, nsString& aFileExtension); @@ -77,79 +75,45 @@ static nsresult GetExtensionFromWindowsMimeDatabase(const nsACString& aMimeType, return NS_OK; } -// We have a serious problem!!
