The most expensive part of random_ref_comp/1 is
do_matches_loop_comp/4. The running time was reduced from roughly
80 seconds to roughly 40 seconds on my computer when I modified
the caller to pre-compile the pattern.
|
|
The time to run io_proto_SUITE:unicode_options_gen/1 on my computer
was about 110 seconds. After modifying the test case so that it
does several file operations in parallel the time was reduced to
about 60 seconds.

This adds three new functions to io_lib - scan_format/2, unscan_format/1,
and build_text/1 - which expose the parsed form of the format control
sequences to make it possible to easily modify or filter the input to
io_lib:format/2. This can e.g. be used in order to replace unbounded-size
control sequences like ~w or ~p with corresponding depth-limited ~W and ~P
before doing the actual formatting.

The returned variable table when linting a map expression shouldn't include
variables that didn't appear in the expression.

Add functions:
ct_release_test:get_app_vsns/2
ct_release_test:get_appup/2
This implies a change in callback functions for ct_release_test, which
now all have two arguments - [CtData,State]. The new CtData is an
opaque data structure which must be given as the first argument to the
two new functions.

The case was discovered where a parent process would exit before closing
the zip file. The result was that a port would be left open
indefinitely, as the small zip server would not detect this condition.
By comparison, the file module will close the associated port when the
parent exits for any reason. This change would make the zip module more
consistent with the semantics of similar modules.
This change is breaking for any callers expecting to pass the handle to
another process for processing (assuming it exits).

The reason for this is a requirement on enabling ssh_sftp to write a tar file on the server.
This new api function is used by ssh_sftp:open_tar/3,4.

If a callback function was terminated with exit/1, there would be no
stack trace in the ERROR REPORT produced by gen_server. This has been
corrected. The actual exit reason for the process is not changed.

* maint:
Fix rare race condition in Dets
|
|
The correction is due to the the evil testcase
dets_SUITE:simultaneous_open(). If the process repairing a Dets file
is killed (should normally never happen), and another process tries to
repair the file, a temporary file from the first process could live on
for a while, even after a successful call to file:delete(). This has
only been seen on W-nd-ows, where it is a known problem.
There are other ways to deal with the problem (rename the file; use
some other filename), but we continue using one certain filename in
order to be as backwards compatible as possible.
