This is introduced by ab435488a.
If a module includes lines which are less than 1, for example a module
which includes `eunit.hrl`, its cover output file misses the coverage lines.

* gomoripeti/tools/cover-no-beam/OTP-12806:
cover: handle undefined module when analysing to file
|
|
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.
|
|
If not unstuck: faulty error messages will appear in error_logger_warn_SUITE.

Applications that use the new erl_anno module are depending on STDLIB 2.5.
Note that CosNotification, Megaco, SNMP, Xmerl, and Parsetools use the
erl_anno module via the Yecc parsers only (the header file in
lib/parsetools/include/yeccpre.hrl calls the erl_anno module).
HiPE does not call the erl_anno module, but uses an exported type.
We have chosen to make HiPE dependent on the erl_anno module.

* maint:
tools: Fix a Unicode bug in the tags module
|
|
|
|
Use the 'raw', 'delayed_write', and 'read_head' options to speed up file
operations. The analysis at the end of:
ts:run(compiler, [batch,cover]).
is now roughly twice as fast.
|
|
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.

An error was introduced in commit f24d1ad9004b2885cd3b15ac0bf9d1407ca68bc8 which
reversed the sorting of all locks. This meant that the least contended locks was
printed instead of the most contended.
This commit reverses the reverse.

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.

Most dependencies introduced are exactly the dependencies to other
applications found by xref. That is, there might be real dependencies
missing. There might also be pure debug dependencies listed that
probably should be removed. Each application has to be manually
inspected in order to ensure that all real dependencies are listed.
All dependencies introduced are to application versions used in
OTP 17.0. This since the previously used version scheme wasn't
designed for this, and in order to minimize the work of introducing
the dependencies.

The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(),
set(), and tid() have been deprecated. They will be removed in OTP 18.0.
Instead the types array:array(), dict:dict(), digraph:graph(),
gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid()
can be used. (Note: it has always been necessary to use ets:tid().)
It is allowed in OTP 17.0 to locally re-define the types array(), dict(),
and so on.
New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2,
queue:queue/1, and sets:set/1 have been added.

As discussed in issue #240 *all* OTP library applications use the '.*'
wildcard as up and down version. This makes library applications
always up- and downgradeable. Using the wildcard version obsoletes
all maintenance tasks regarding library applications' appup files.
Additionally, it prevents upgrade problems caused by automatically
included application dependencies when using reltool to create
releases. Missing copyright headers are now consistently present.

The raw_abstract_v1 format that is currently used was introduced
in R9C. Beam files that old cannot be executed by the current
run-time system, so there is no need to continue the old formats.
Removing the support will increase coverage.

We want to see at least some coverage of cover itself.

This adds optional names to fun expressions. A named fun expression
is parsed as a tuple `{named_fun,Loc,Name,Clauses}` in erl_parse.
If a fun expression has a name, it must be present and be the same in
every of its clauses. The function name shadows the environment of the
expression shadowing the environment and it is shadowed by the
environment of the clauses' arguments. An unused function name triggers
a warning unless it is prefixed by _, just as every variable.
Variable _ is allowed as a function name.
It is not an error to put a named function in a record field default
value.
When transforming to Core Erlang, the named fun Fun is changed into
the following expression:
letrec 'Fun'/Arity =
fun (Args) ->
let <Fun> = 'Fun'/Arity
in Case
in 'Fun'/Arity
where Args is the list of arguments of 'Fun'/Arity and Case the
Core Erlang expression corresponding to the clauses of Fun.
This transformation allows us to entirely skip any k_var to k_local
transformation in the fun's clauses bodies.

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

files as delimiters.
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
waiting for cover data from the node would hang forever. This has been
corrected.

Commit 29231033 made cover fall back to compile info if source was not
found in pwd or ../src. This isn't sufficient for source that lies in
subdirectories of ../src when beams and source have been moved since
compilation (eg. install of some OTP applications), so first try finding
source relative to the beam directory.
For example, given a beam path
/installed/path/to/app-1.0/ebin/root.beam
and a source path
/compiled/path/to/app/src/subdir/root.erl
then look for
/installed/path/to/app-1.0/ebin/../src/subdir/root.erl
before the source path.
