2017-11-09Fix deflateParams on zlib 1.2.11John Högberg
1.2.11 started bailing when avail_out==0 regardless of whether there's anything to flush or not, and there's no point in adapting the old method since it was vulnerable to bugs in other zlib versions which updated the deflate parameters even on failure. The api_deflateParams test has been expanded accordingly, and two white-box cases in zip_usage has been updated to make fewer assumptions about the output; the validity of the compressed data is what matters, not whether it's exactly the same as the test vector.

2017-10-23erts: Fix so that bind correct schedulersLukas Larsson
When the cpu ids and scheduler ids don't match, the end schedulers could end up not being bound when they should be. example: > taskset -c 1-3 erl +S 4 +sbts > erlang:system_info(scheduler_bindings). {1,2,3,unbound} This fix makes it so that all cores are used to bind schedulers.

2017-10-02erts: Fix bug when detecting bad dist messageSverker Eriksson
We can't just leave it in queue with dist_ext=NULL. Two symptoms seen: 1. 'receive' trying to deref dist_ext as NULL. 2. GC think it's a term and put THE_NON_VALUE in root set.

2017-10-02Fix zlib merge snafuJohn Högberg
I accidentally merged a few fixes directly to maint-20 (and then to maint and master), instead of merging to maint and master and waiting for a patch to merge it into maint-20, leaving the related tickets dangling. This commit does nothing beyond getting the tickets (and their release notes) into the next patch.
2017-09-29Fix gunzip/1 of concatenated gzip filesJohn Högberg
Quoting RFC 1952: "A gzip file consists of a series of "members" (compressed data sets). [...] The members simply appear one after another in the file, with no additional information before, between, or after them."
2017-09-29Fix minor incompatibilities in inflate behaviorJohn Högberg
When presented with multiple valid but concatenated streams, the old driver returned an empty result once the end of the first stream was reached, and kept doing so even if fed new data. The new driver/NIF returned a data_error instead. zlib:inflateInit/3 has been added to control this behavior, but is not yet ready for public use.

2017-09-22Correctly append sub-binaries in iolist_to_iovecJohn Högberg
The byte_offset of sub-binaries wasn't taken into account for ProcBins, subtly ruining the results. The test suite didn't catch it since it didn't check for sub-binaries in particular, and only checked for equality between variations -- not whether the output was equal to the input.

2017-09-14Document that the compiler may optimize away atomsBjörn Gustavsson
The following code could fail in the call to list_existing_atom/1: String = atom_to_list(some_atom), Atom = list_to_existing_atom(String) because the compiler will rewrite the code to: String = "some_atom", Atom = list_to_existing_atom(String) If some_atom is not used in another place, it will not exist. The compiler could be updated to preserve the atom in this simple case, but it would be hard to make sure that the compiler never loses atoms that exist in the source text. It also difficult to imagine a real world use case where this would be a problem. If an atom is mentioned only in a way that the compiler can optimize away, is there really any need to create the atom at all in list_to_existing_atom/1? Therefore, it is better to place the responsibility that the atom exists on the user of list_to_existing_atom/1. Update the documentation to mention that the compiler may optimize away atoms. https://bugs.erlang.org/browse/ERL-453

Symptom: VM crash when erlang:trace_pattern(on_load, ..) is set and module with -on_load is loaded. Problem: Tracing and -on_load clash in their use of Export.beam[1] Solution: Do not do call set_default_trace_pattern in finish_loading_1 for modules with -on_load. finish_after_on_load_2 will do that anyway.
