2017-10-18Bump version of crash dumps to 0.4Björn Gustavsson
2017-10-18Don't dump literal areas that are not referenced at allBjörn Gustavsson
2017-10-18Dump literals separately to avoid incomplete heap dataBjörn Gustavsson
When a literal was used from several processes, the literal would be dumped in only one of the processes. The other processes that referenced the literals would have incomplete heap data.
2017-10-18Implement dumping of maps in crash dumpsBjörn Gustavsson
Maps would be dumped as the atom 'undefined', which is not very informative.
2017-10-18Buffer writing of crash dumpsBjörn Gustavsson
Writing of crash dumps were done using unbuffered IO. This is slow since many small writes are done. Use a FILE* with an allocated buffer to obtain buffered IO. I wrote a small test program that created 50000 binaries of 200 bytes each and then created a crash dump. The crash dumping was an order of magnitude faster with buffered IO than without.

2017-10-09erts: Fix caller trace for apply bifsLukas Larsson
Bifs that are called through the export entry using i_call_last could have their cp set to return_trace, just like any other call. So we have to unwind the trace stack to get the correct cp. Not doing this creates a lot of issues for fprof.

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.

2017-09-29Fix 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.

2017-09-13erts: Fix 'on_load' tracing bug for modules with -on_loadSverker Eriksson
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.

All operations will now yield appropriately, allowing them to be used freely in concurrent applications. This commit also deprecates the functions listed below, although they won't raise deprecation warnings until OTP 21: zlib:adler32 zlib:crc32 zlib:inflateChunk zlib:getBufSize zlib:setBufSize The behavior of throwing an error when a dictionary is required for decompression has also been deprecated.

2017-09-01Make cp_pos_to_col function aware of the ANSI escape codesGlauber Campinho
This fixes the issue with the function `move_cursor` described in #1536 and that causes the bug described in https://github.com/elixir-lang/elixir/issues/6504. The function `cp_pos_to_col` maps the current position in the buffer to the correct column on the screen, but it didn't handle ANSI escape codes. Since the ANSI escape codes aren't visible, the `cp_pos_to_col` now skips them when executing the calculations using `ansi_escape_width`. This new function only considers color escape codes, but also handles invalid codes.
