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.
|
|
Maps would be dumped as the atom 'undefined', which is
not very informative.
|
|
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.

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.

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.

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.

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.

sverker/on_load-on_load-bug/OTP-14612
|
|
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.

After deleting the chars the function `del_chars` was considering the code points to move the cursor back and not the graphemes

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.

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.
