Fetch and present arity in the *xref* window (unless too many hits).
If we are reasonably sure which definition the user wants to go to
then jump there directly instead of popping to the *xref* window.

Use `counters:add/3` instead of `ets:update_counter/3`
for counting the number of times a line is executed.
By default, the reference to the counter array for each module will be
stored in a persistent term and retrieved every time a counter is
updated. This makes the compiler test suite with coverage enabled run
*almost* twice as fast (on my computer, in about 6 minutes down from
more than 11 minutes).
To get even more speed, the new `cover:local_only/0` function can be
called to put cover into a mode where the cover-compiled code can only
be run on the local node. In this mode, the cover-compiled modules in
a more efficient way by compiling the counter reference into the
code. This shaves off about one more minute, making the compiler test
suite with coverage enabled run *more than* twice as fast (in about 5
minutes on my computer).

The SSA compiler branch is smart enough to recognize that the code
past 'after infinity' is unreachable, so our test vectors weren't
always kept alive.

jhogberg/john/erts/cross-type-carrier-migration/OTP-15063
Allow carrier migration between different allocator types
|
|
|
|
|
|
|
|
|
|
|
|
This commit replaces the old memory instrumentation with a new
implementation that scans carriers instead of wrapping
erts_alloc/erts_free. The old implementation could not extract
information without halting the emulator, had considerable runtime
overhead, and the memory maps it produced were noisy and lacked
critical information.
Since the new implementation walks through existing data structures
there's no longer a need to start the emulator with special flags to
get information about carrier utilization/fragmentation. Memory
fragmentation is also easier to diagnose as it's presented on a
per-carrier basis which eliminates the need to account for "holes"
between mmap segments.
To help track allocations, each allocation can now be tagged with
what it is and who allocated it at the cost of one extra word per
allocation. This is controlled on a per-allocator basis with the
+M<S>atags option, and is enabled by default for binary_alloc and
driver_alloc (which is also used by NIFs).

Split the manual testcase and run them in daily tests instead.
Easy to run directly as well:
(cd ../test; cerl -eval "emacs_SUITE:indent([])")

lcnt:collect is documented as implicitly starting the lcnt server
but didn't do so prior to this commit. I've decided to extend this
behavior to all operations as the overhead is negligible and it's
a bit more convenient to use.

tools: Correct a counting bug in Cover
|
|
See also PR #1641, https://github.com/erlang/otp/pull/1641.
The bug was introduced in commit ab435488a (Erlang/OTP 18).

The tests assume that the most active process will be the current
one, which is no longer true since the delayed_write option now
uses a wrapper process for much of its work.
The timeout for this test has been increased to account for the
lack of delayed_write; 60s was enough for everything except the
debug build on some machines.

erlang:is_builtin(erlang, M, F) returns false for apply/2 and
yield/0. The documentation for erlang:is_builtin/3 says that it
returns true for BIFs that are implemented in C. apply/2 and
yield/0 are implemented in C (as BEAM instructions), and
therefore the correct return value is true.
Also see a similar argument that was made for apply/3 in the past:

It is assumed that I/O devices can handle character codes greater
than 255.

The updates of xref_base:analysis() are cosmetic (the strings are
parsed by the Erlang scanner only).

* bjorn/stdlib/erl_tar/OTP-14278:
erl_tar: Handle leading slashes and directory traversal attacks
Don't create absolute path names in tar files
|
|
We should not assume that erl_tar will allow unpacking tar files
with absolute path names for archive members.
|
|
This is to ensure that files are recompiled if a .hrl file in the
current directory is changed.
|
|
|
|
This allows build scripts to use emake without needing to generate
an Emakefile before running make:all/0,1 or make:file/1,2.
