on machines with long host names. Move forward the file location interval to corrupt. An ETS table file corrupted in the header may still be readable with table content unchanged and that will cause tabfile_ext4 to fail. The header length increase with long host names and added table options.
2019-08-22Fix filelib:wildcard/1,2 for patterns containing ".." and/or "@"Björn Gustavsson
`..` was broken and only worked when it was used in the beginning of the pattern before any wildcard characters. For example: 1> filelib:wildcard("erts/.."). ["erts/.."] Using `..` preceded by wildcard characters would not work: 1> filelib:wildcard("*/.."). [] `@` is not a wildcard character but is used internally in `filelib` as an escape character and was not handled as other literal characters. That could lead to performance degradation as it disabled an optimization of the matching of the literal prefix of a pattern. It would also cause the following example to fail: 1> filelib:wildcard("@/.."). [] This commit corrects the handling `..` and also makes sure that the use of `@` in a pattern does not degrade performance. https://bugs.erlang.org/browse/ERL-1029

2019-08-09erts: Create heap binaries in bs_get_binary2John Högberg
ErlSubBin is a large struct that often dwarfs the region of memory it points at, and it's common for them to refer to a ProcBin which must be kept around as long as the SubBin lives, using up even more heap space and keeping the referenced binary alive regardless of how small the sub-binary is.

Code such as ets:fun2ms(fun({"foo" ++ X}) -> X end) works fine in compiled code. Let's make it work when fun2ms is invoked from the shell as well.

CMP_TERM returned an `Sint`, which overflowed the `int` used in erl_rbtree for storing the comparison, causing list subtraction to behave strangely.

* kjell/stdlib/ets_ordered_set_slow_react/OTP-15906: ETS ordered_set: Improvements to the CA tree implementation
2019-06-18ETS ordered_set: Improvements to the CA tree implementationKjell Winblad
This commit only affects the implementation of ETS `ordered_set` tables with the `write_concurrency` option enabled. Such tables are implemented with a data structure that is called the contention adapting search tree (CA tree). This commit introduces the following changes: * This commit causes a join to be triggered in one randomly selected base node in about one of 1000 read unlock calls for base node locks. No such joins happened before this commit. Before this commit, operations that only acquired looks in read-mode never triggered any contention adaptation. Therefore, the CA tree could get stuck in a sub-optimal state in certain scenarios. This could happen, for example, when a CA tree is first populated with parallel inserts (which will cause splits of base nodes) and then only read-only operations are applied to the data structure. Benchmark results from the `ets_SUITE:lookup_catree_par_vs_seq_init_benchmark/0` benchmark function (which is included in this commit) shows that this change can improve the throughput of the CA tree in the scenario described above. * Read-only operations will now also increase values of statistics counters when they detect that they need to wait for other operations. Only write operation changed statistics counters before this commit. This improves the statistics that the adaptation heuristics is based on. * Additionally, this commit adds an upper and lower limit to the contention statistics variables in the base nodes. Such limits did not exist before this commit. This should, for example, make the CA tree more responsive to contention after long periods of low contention.
