erlang:is_builtin(erlang, apply, 3) returns 'false'. That seems to be
an oversight in the implementation of erlang:is_builtin/3 rather than
a conscious design decision. Part of apply/3 is implemented in C (as a
special instruction), and part of it in Erlang (only used if apply/3
is used recursively). That makes apply/3 special compared to all other
BIFs.
From the viewpoint of the user, apply/3 is a built-in function,
since it cannot possibly be implemented in pure Erlang.

If a module includes eunit.hrl, a parse transform adds the function
test/0 on line 0 in the module. A bug in OTP-18.0 caused
cover:analyse_to_file/1 to fail to insert cover data in the output
file when line 0 existed in the cover data table. The bug is corrected
by the commit "Fix cover output file".
This commit adds a test which checks that the bug is not introduced
again.

It is possible that not just the source but even the beam of a module
is not available when calling analyse_to_file.
For example when coverdata is imported from an old file and since then
a module was removed.
Before this fix cover:analyse_to_file/3 could possibly never return
because of a helper process crashed with error:undef and never reply
to the caller.
At the same time link the helper process to cover_server so any
further error won't let the caller waiting indefinitely.

Add functions for cover compilation and analysis on multiple
files. This allows for more parallelisation.
All functions for cover compilation can now take a list of
modules/files.
cover:analyse/analyze and cover:analyse_to_file/analyze_to_file can be
called without the Modules arguement in order to analyse all cover
compiled and imported modules, or with a list of modules.
Also, the number of lookups in ets tables is reduced, which has also
improved the performance when analysing and resetting cover data.

OTP-8188 introduced a fix for handling last expressions in
expressions like case, try and friends. However the fix did
not account that some of those expressions like receive may
have no clauses (only an after clause), leading to a function
clause error when cover compiling code with such expressions.

Replace the 'erlang:binary_to_term/1' and 'erlang:binary_to_term/2'
Erlang wrappers taking care of failure after yield with management
of this in the hidden yield BIF.

The reconnect/1 test starts another node and takes down the connection
to it for a while. However, it has been in observed in our daily builds
that sometimes a "spontaneous" re-connection occurs.
I think that it because of the call to rpc:cast/3 which internally
will set the group leader for the remote process to a process on
the test_server node. It seems that sometimes the group_leader/2
call will re-establish the connection. Unfortunately, I have not
been able to force this to happen by inserting delays in the rpc
module, so it it still just an hypothesis.
However, letting the other node do the disconnection does seem to fix
the problem and intuitively that should be safer way to do it because
the group_leader/2 call and the disconnection will be executed
sequentially on the same node instead of concurrently from two
different nodes.

Add the mentioned test suites for *all* library and touched
non-library applications.

eprof does not work on native-compiled code. Since
eprof_SUITE:basic_option/1 does profiling on the lists modules,
the test case will fail if --enable-native-libs is used.
|
|
We used to skip the entire test suite if the cover server had already
been started by common_test, but that means that we will get bad
coverage for the cover module.
Modify the test suite to to run all tests case that don't explicitly
start or stop the cover server to increase the coverage. In addition,
add a special coverage_analysis/1 test case that only runs when
the cover server is already running.

Similarly to cover compiling from source
(in this case some user specified compiler options are allowed)
when cover compiling from existing beam
take a filtered list of compiler options from the beamfile.
This way e.g. export_all can be preserved. See use case in eb02beb1c3

While working on a tool that processes Erlang code and testing it against this repo,
I found out about those little sneaky 0xff. I thought it may be of help to other
people build such tools to remove non-conforming-to-standard characters.

When cover:stop(Node) was called on a non-existing node, a process

* jv/cover-patches/OTP-10778:
Fix a bug in cover when used with no_auto_import
Ensure cover keeps the proper file source
cover now relies on the compile info to find file sources
|
|
|
|
Cover was rewriting guard clauses as non-remote calls.
That said, if a guard contains erlang:is_binary(Binary),
Cover was incorrectly removing the erlang prefix which
lead to errors if is_binary is not auto imported.
This commit keeps the abstract format as it is.
|
|
Whenever a module is compiled via compile:forms/2,
the source is set to current directory unless a source
option is passed to compile. This commit ensures that
cover passes the source information to compile:forms/2
to ensure the source won't be modified after the module
is cover compiled.
|
|
Prior to this commit, cover relied on a simple heuristic that
traverses directory from the beam file to find a source file.
The heuristic was maintained with this patch but, if it fails,
it fallbacks to the source value in the module compile info.
In order to illustrate how it works, one of the tests that
could not find its source now passes successfully (showing the
source lookup is more robust).

If one test failed, the next would sometimes also fail since cover was
not stopped.
|
|
Adding a timer:sleep between these two lines:
net_kernel:disconnect(N1),
[] = cover:which_nodes(),
This is to make sure the disconnect is detected by cover before
checking that the node is gone.
|
|
A nodes that was stopped with cover:stop/1 while marked as lost would
not be removed from the list of lost nodes. Therefore, if a nodeup was
later received for a node with the same name, it would be
reconnected. This has been corrected.

OTP-10523
Earlier, if the connection to a remote cover node was lost, all cover
data was lost and the cover_server on the remote node would die. This
would cause problems if there were cover compiled modules that would
still be executed since they would attempt to write to the no longer
existing ets tables belonging to the cover_server.
This commit changes this behavior so that the cover_server on the
remote node will survive connection loss and continue collecting cover
data. If the connection is re-established then the main node will sync
with the remote node again and cover data will not be lost (unless the
node was down).
