2018-12-13erts: Fix seq_trace:reset_trace dirty gc bugLukas Larsson
When seq_trace:reset_trace could be called while a process was doing a dirty GC. This triggered a race where all signals was moved to the internal signal queue during the GC which in turn caused the a heap overrun problem. This fix makes it so that the main and msgq lock are taken before the clear. This will make sure that we are allowed to do the clear.

2018-11-13Avoid closing files in gc/monitor callbacksJohn Högberg
Closing files in these callbacks could block scheduler progress and cause major system instability. We now defer these operations to a dedicated process instead. This process may in turn block forever and prevent further orphaned files from being closed, but it will keep the emulator itself from misbehaving.

2018-11-06Add a persistent term storageBjörn Gustavsson
Persistent terms are useful for storing Erlang terms that are never or infrequently updated. They have the following advantages: * Constant time access. A persistent term is not copied when it is looked up. The constant factor is lower than for ETS, and no locks are taken when looking up a term. * Persistent terms are not copied in garbage collections. * There is only ever one copy of a persistent term (until it is deleted). That makes them useful for storing configuration data that needs to be easily accessible by all processes. Persistent terms have the following drawbacks: * Updates are expensive. The hash table holding the keys for the persistent terms are updated whenever a persistent term is added, updated or deleted. * Updating or deleting a persistent term triggers a "global GC", which will schedule a heap scan of all processes to search the heap of all processes for the deleted term. If a process still holds a reference to the deleted term, the process will be garbage collected and the term copied to the heap of the process. This global GC can make the system less responsive for some time. Three BIFs (implemented in C in the emulator) is the entire interface to the persistent term functionality: * put(Key, Value) to store a persistent term. * get(Key) to look up a persistent term. * erase(Key) to delete a persistent term. There are also two additional BIFs to obtain information about persistent terms: * info() to return a map with information about persistent terms. * get() to return a list of a {Key,Value} tuples for all persistent terms. (The values are not copied.)

2018-10-19Fix hanging gen_tcp send vs close raceRaimo Niskanen
While a gen_tcp send was in progress with filled buffers and slow receiver a close (from another process) would place the port in a half dead state so the port could not signal back to send, that waited for confirmation. The solution is to after some time (5 s) of waiting for send confirmation set a monitor on the port, which detects if the port becomes half dead due to close from another process. The close pending loop has also been improved to use the linger timeout for waiting, and to set a system timeout (arbitrarily selected 3 min) to not wait forever when the other end reads data s l o w l y (tarpitting, kind of).

2018-10-11"cork" tcp socket around file:sendfileIgor Slepchin
This fixes 200ms delay on the last TCP segment when using file:sendfile/2 on Linux (ERL-698).
2018-10-11Add nopush TCP socket optionIgor Slepchin
This translates to TCP_CORK on Linux and TCP_NOPUSH on BSD. In effect, this acts as super-Nagle: no partial TCP segments are sent out until this option is turned off. Once turned off, all accumulated unsent data is sent out immediately. The latter is *not* the case on OSX, hence the implementation ignores "nopush" on OSX to reduce confusion.
2018-10-02Implement {netns,NS} option for inet:getifaddrs/1Raimo Niskanen
Also implement the same option for the legacy undocumented functions inet:getif/1,getiflist/1,ifget/2,ifset/2. The arity 1 functions had before this change got signatures that took a socket port that was used to do the needed syscall, so now the signature was extended to also take an option list with the only supported option {netns,Namespace}. The Socket argument variant remains unsupported. For inet:getifaddrs/1 the documentation file was changed to old style function name definition so be able to hide the Socket argument variant that is visible in the type spec. The arity 2 functions had got an option list as second argument. This list had to be partitioned into one list for the namespace option(s) and the other for the rest. The namespace option list was then fed to the already existing namespace support for socket opening, which places the socket in a namespace and hence made all these functions that in inet_drv.c used getsockopt() work without change. The functions that used getifaddrs() in inet_drv.c had to be changed in inet_drv.c to swap namespaces around the getifaddrs() syscall. This functionality was separated into a new function call_getifaddrs().
