Try write directly to process heap (as before) if the term is guaranteed not to contain any big maps that may break the initial size estimation.

2015-06-15erts: Remove hashmap probabilistic heap overestimationSverker Eriksson
by adding a dynamic heap factory. "binary_to_term" is now a hybrid solution with both a call to decoded_size() to calculate needed heap space AND possible dynamic allocation of more heap space if needed for big maps. The heap size returned from decoded_size() is guaranteed to be sufficient for all term heap data except for hashmap nodes. All hashmap nodes are created at the end of dec_term() by invoking the heap factory interface that may allocate more heap space on process heap or in fragments. With this commit it is no longer guaranteed that a message is confined to only one heap fragment.

2015-06-15erts: Optimize maps:mergeSverker Eriksson
to be better at reusing entire hashmap sub-trees. Sub-tree reuse is detected in three cases: 1. The sub-tree top node does not exist at all in the other map. Already implemented before this commit. 2. The exact same sub-tree exist in both maps. Must calculate nr of keys in tree to get total size right. 3. We detect that a sub-tree only contains stuff from one of the maps. There is still one case we don't detect. If A and B leafs have equal keys we could also compare the values. If values are equal, further node reuse could propagate up toward the root (by 'mix'==0). The downside would be potentially expensive value comparisons.

The parenthesized type with tag 'paren_type' is no longer created by the Erlang Parser as of OTP 18.0. The tag 'user_type' is used for user defined types as of OTP 18.0. In releases before commit 7ad783 'type' is used.

Add a check to protect from segfault when erlang:get_module_info/1/2 is called on a deleted module (i.e. with no current code). Also refactor erts_module_info_0/1 to avoid repeated calls to erts_active_code_ix() and remove some obsolete comments. Add test for module_info on deleted modules.

2015-06-09Fix socket option {linger, {true, 0}} to abort TCP connectionsRory Byrne
Up until now, if {linger, {true, 0}} is set on the socket and there is data in the port driver queue, the connection is not aborted until the port queue is empty and close() is called on the underlying file descriptor. This bug allows an idle TCP client to prevent a server from terminating the connection and freeing resources. This patch fixes the problem by discarding the port queue if the socket is closed when {linger, {true, 0}} is set.
2015-06-09Apply 'show_econnreset' socket option to send errors as wellRory Byrne
Up till now all send errors have been translated into a generic {error, closed}. This patch allows {error, econnreset} to be returned on send errors when it is detected that the TCP peer has sent an RST.
2015-06-09Add 'show_econnreset' TCP socket optionRory Byrne
An ECONNRESET is a socket error which tells us that a TCP peer has sent an RST. The RST indicates that they have aborted the connection and that the payload we have received should not be considered complete. Up until now, the implementation of TCP in inet_drv.c has hidden the receipt of the RST from the user, treating it as though it was just a FIN terminating the read side of the socket. There are many cases where user code needs to be able to distinguish between a socket that was closed normally and one that was aborted. Setting the option {show_econnreset, true} enables the user to receive ECONNRESET errors on both active and passive sockets. A connected socket returned from gen_tcp:accept/1 will inherit the show_econnreset setting of the listening socket. By default this option is set to {show_econnreset, false}. Note that this patch only enables the reporting of ECONNRESET when the socket is being read from. It does not report ECONNRESET (or EPIPE) when the user tries to write to a connection when an RST has already been received. Currently the TCP implementation in inet_drv.c hides all such send errors from the user in favour of returning {error, close}. A separate patch will be needed to enable the reporting of such errors.

All flags was not always set when setting multiple aux work flags at once. This scenario is fortunately quite uncommon and only caused further delay in memory deallocations.
