| 2016-01-07 | beam_bool: Fix unsafe optimization | Björn Gustavsson | |
| beam_bool would make the following code unsafe (which would be reported by beam_validator): scotland(Echo) -> found(case Echo of Echo when true; Echo, Echo, Echo -> Echo; echo -> [] end, Echo = placed). found(_, _) -> million. Basically, beam_bool would see that the 'case' would always return the value of Echo. Thus: scotland(Echo) -> found(Echo, Echo = placed). The only problem is that beam_bool would also remove a 'move' instruction that would save Echo to the stack. Here is the assembly code for part of the function: {allocate_zero,1,1}. {move,{x,0},{y,0}}. %% Save Echo on stack. {bif,'=:=',{f,7},[{x,0},{atom,true}],{x,1}}. {bif,'=:=',{f,7},[{x,0},{atom,true}],{x,2}}. {bif,'=:=',{f,7},[{x,0},{atom,true}],{x,3}}. {bif,'and',{f,7},[{x,2},{x,3}],{x,2}}. {bif,'and',{f,7},[{x,1},{x,2}],{x,1}}. {jump,{f,8}}. {label,7}. {move,{atom,false},{x,1}}. {label,8}. {bif,'or',{f,6},[{atom,true},{x,1}],{x,1}}. {test,is_eq_exact,{f,6},[{x,1},{atom,true}]}. %% Jump never taken. {jump,{f,5}}. {label,6}. {test,is_eq_exact,{f,9},[{x,0},{atom,echo}]}. {move,nil,{x,0}}. {jump,{f,5}}. {label,9}. {test_heap,3,0}. {put_tuple,2,{x,0}}. {put,{atom,case_clause}}. {put,{y,0}}. {line,[{location,"t.erl",5}]}. {call_ext,1,{extfunc,erlang,error,1}}. {jump,{f,5}}. {label,5}. {test,is_eq_exact,{f,12},[{atom,placed},{y,0}]}. beam_bool would see that the is_eq_exact test at label 8 would always succeed. It could therefore remove most of the code before the jump to label 5. Unfortunately it also removed the essential move of Echo to the stack: {allocate_zero,1,1}. %% Instruction incorrectly removed: {move,{x,0},{y,0}}. {jump,{f,5}}. {label,5}. {test,is_eq_exact,{f,12},[{atom,placed},{y,0}]}. The root cause of the problem is that the 'move' instruction is included in the block of 'bif' instructions before label 8. Normally the 'move' instruction would not have been discarded, but because the left operand to the 'or' BIF is 'true', the entire block with 'bif' instructions are dropped. As far as I can see, there is no gain by including 'move' instructions in the first place. There is no way that better code will be produced. In fact, the entire optimization can be given up if 'move' instructions are found in the block. Thus we can fix this bug by never including any 'move' instructions in the block of 'bif' instructions. We can also remove all the code that deals with 'move' instructions within blocks. Reported-by: Thomas Arts | |||
| 2016-01-01 | Do not consider "." part of names in edlin | José Valim | |
| Today, if you press Ctrl+W inside erl, it will erase word chars including dots. This may have made sense in the past when Erlang had packages, but today considering the most common case for dots inside erl is to work with records, considering the dot part of the word is rather a mistake. For example, imagine the following code, where [] is the cursor: 1> S#elixir_scope.name[] When I press Ctrl+W it erases all up to #: 1> S#[] This patch changes it to the dot is no longer considered part of the name: 1> S#elixir_scope.[] Which is rather expected behaviour for most use cases of dot in Erlang. | |||

| 2015-12-21 | Make peer handling more efficient | Anders Svensson | |
| Each service process maintains a dictionary of peers, mapping an application alias to a {pid(), #diameter_caps{}} list of connected peers. These lists are potentially large, peers were appended to the end of the list for no particular reason, and these long lists were constructed/deconstructed when filtering them for pick_peer callbacks. Many simultaneous outgoing request could then slow the VM to a crawl, with many scheduled processes mired in list manipulation. The pseudo-dicts are now replaced by plain ets tables. The reason for them was (once upon a time) to have an interface interchangeable with a plain dict for debugging purposes, but strict swapablity hasn't been the case for some time now, and in practice a swap has never taken place. Additional tables mapping Origin-Host/Realm have also been introduced, to minimize the size of the peers lists when peers are filtered on host/realm. For example, a filter like {any, [{all, [realm, host]}, realm]} is probably a very common case: preferring a Destination-Realm/Host match before falling back on Destination-Realm alone. This is now more efficiently (but not equivalently) expressed as {first, [{all, [realm, host]}, realm]} to stop the search when the best match is made, and extracts peers from host/realm tables instead of searching through the list of all peers supporting the application in question. The code to try and start with a lookup isn't exhaustive, and the 'any' filter is still as inefficient as previously. | |||

| 2015-12-18 | TLS distribution: bind erts socket to localhost | Magnus Henoch | |
| There is no reason for the socket on the erts side of the proxy to accept connections from other hosts, so let's bind it to the loopback interface. Also change {ip, {127,0,0,1}} to {ip, loopback} for the erts side of the socket for outgoing connections, to avoid hardcoding IPv4. | |||

| 2015-12-16 | Fix compilation of matching with UTF binaries | Kostis Sagonas | |
| The code generated by the HiPE compiler for pattern matching with UTF binaries was such that sometimes THE_NON_VALUE was stored in the roots followed by the garbage collector. This was not an issue for the vanilla native code compiler, but was problematic for the ErLLVM back-end. Fix the issue by not storing THE_NON_VALUE in the live roots. An alternative fix would be to change the code of the garbage collector. With this fix, there are no more (known) failing test cases for the ErLLVM back-end (at least on x86_64 with LLVM 3.5, which is the configuation regularly tested). Thanks to @margnus1 for the fix. | |||
