It makes no sense to be able to do `<<...,Rest/binary>> <= ...` in a
comprehension. The related Dialyzer test is removed.

In an email to erlang-questions, Bengt Kleberg wrote:
When I use c:ls/1 it reminds me so much of Unix "ls" that I
expect c:ls("filename") to work. The resulting error surprises
me every time (not the same day).
While teaching c:ls/1 to show non-directory files, update the
error handling to make use of the POSIX error codes from
file:list_dir/1 and file:format_error/1 (which had not been
invented when the c module was first implemented).

This test always fails when gen is native compiled, since the
optmization is not implemented then. The test is now skipped when
running with hipe.
The test does also quite often fail on one of the test hosts which
runs in a virtual machine. The reason is that the clock runs "in
bursts" on this host, which is outside of the control of the erlang VM
and probably due to the fact that the host runs as a virtual
machine. To overcome this problem, the echo message is now sent 10000
times instead of 10 times - i.e. the test run is prolonged in order to
even out the effect of the bursts.

This test fails on a test host where no proper unix unzip is
installed. This has been corrected.

This function is used all over the place in OTP itself and people
sometimes want that functionality, they may as well not reimplement it
themselves.

When entering a new file, epp doesn't properly set #epp.name2 like it
does on initialisation, generating a malformed file attribute when it
leaves the file.

* bjorn/fix-encoding/OTP-11041:
Encode Erlang source files with non-ascii characters in UTF-8

To ensure that 'master' compiles when we merge 'maint' to it,
regardless of which encoding is default in 'master', all source
files with non-ascii characters *must* have the encoding specified.

In rest_for_one and one_for_all supervisors one child dying can cause
multiple children to be restarted. Previously if the child that caused
the restart is started successfully but another child fails to start,
the supervisor would not terminate this child with the other
successfully restarted children as no record of the pid was kept. Thus
the supervisor would try to start this child again. This could lead to
multiples of the same child or if the child is registered cause repeated
attempts at starting this child - until the max restart threshold was
reached.
Now the child that failed to start becomes the restarting child, instead
of staying with the same child, for the next restart attempt. This has
the following side effects:
1) In one_for_all the new version of the child that original died is
terminated before a restart attempt is made.
2) In rest_for_one all succesfully restarted children are not terminated
and restarting continues from the child that failed to start.

At Erlang Factory 2013 there was discussion during one of the talks about
the sys:get_status functions and how useful they were for debugging. Geoff
Cant mentioned it would be very useful if the sys module also provided
functions to use while debugging to get just the state of a process and
also to be able to replace the state of a process, and many others in the
audience appeared to agree.
The sys:get_state/1,2 functions return the state of a gen_server, gen_fsm,
or gen_event process. The return value varies depending on the process
type: process state for a gen_server, state name and state data for a
gen_fsm, and handler module, handler id, and handler state for each handler
registered in a gen_event process.
The sys:replace_state/2,3 functions allow the state of a gen_server,
gen_fsm, or gen_event process to be replaced with a new state. These
functions take a function argument that updates or replaces the process
state; using a function to change the state eliminates the race condition
of first reading the state via sys:get_state/1 or sys:get_state/2, using
its return value to create a new state, and then replacing the old state
with the new state, since during that time the process might have received
other calls or messages that could have changed its state.
* For a gen_server process, the state replacement function takes the
process state as an argument and returns a new state.
* For a gen_fsm process, the state replacement function gets a tuple of
{StateName, StateData} and returns a similar tuple that specifies a new
state name, new state data, or both.
* For a gen_event process, the state replacement function is called for
each registered event handler. It gets a tuple {Module, Id, HandlerState}
and returns a similar tuple that specifies the same Module and Id values
but may specify a different value for HandlerState.
If the state replacement function crashes or results in an error, the
original state of a gen_server or gen_fsm process is maintained; if such a
crash occurs for a gen_event process, the original state of the event
handler for which the state replacement function was called is maintained,
but the states of other event handlers of the same gen_event process may
still be updated if no errors or crashes occur while replacing their
states.
Add documentation for sys:get_state/1,2 and sys:replace_state/2,3. The
documentation explicitly notes that the functions are intended for use
during debugging.
Add new tests for these functions to gen_server_SUITE, gen_fsm_SUITE, and
gen_event_SUITE.

A bug has been fixed: when given the option {encoding,utf8} a list of
floating point numbers (in the correct interval) was mistakenly
returned as a string.
|
|
The scanner did not crash when a floating point number was encountered
in the input string.

Remove the call trace from this testcase as we cannot guarantee named
table to be gone until ets:delete returns anyway.
