In binary matching, there must only be one "tail segment" (i.e.
a size-less segment of type binary) and it must be last. Thus,
the compiler will reject the following function definition:
foo(<<A/bits,B/bits>>) -> ok.
But code such as the following:
[42 || <<_:8/integer, _/bits>> <= Bits]
will internally (in the Core Erlang format) be translated to a
binary matching pattern containing two tail segments. The compiler
happens to generate correct code anyway (later passes will get
rid of the redundant tail segment), but it is ugly and will
confuse tools such as Dialyzer.
Change the transformation of binary generators (in both list and
binary comprehensions) not to generate add a tail segment if there
already is one.
|
|
In the code for handling binary generators (in list and binary
comprehensions), factor out the code for appending a match-all tail
segment onto a pattern into a separate function. That will only
make the code somewhat simpler, but will facilitate fixing a
bug/misfeture in the next commit.

The OtpMbox class was missing the hash() method while overriding
equals(). This can cause problems when using jinterface in a
larger Java application.

Files (actually one file - multitrace.erl), marked as EXAMPLE_FILES are

This file should be installed into $(RELSYSDIR)/examples directory.

For platforms that support writev, ei uses iovec structures to be able
to easily send noncontiguous data buffers. When sending large
messages, the socket can of course block, in which case ei adjusts its
iovecs to pick up where it left off when the socket becomes writeable
again. Unfortunately the code that handled the case when the number of
bytes written are less than the current iovec size adjusted only the
iovec byte count but not the iovec data pointer, resulting in the same
data being sent multiple times.
The fix is trivial: in addition to subtracting the count of bytes
already written from the current iovec's size, also increment the
current iovec's data pointer by the number of bytes already written.
Tested manually on Linux and verified to fix a problem detected in
production with writing large binaries from a cnode to a regular
node. No unit tests were added, however, because they use the local
loopback which acts more like a pipe than an inter-host TCP
connection. The closing of the TCP window on the receiving side and
the resultant write blocking on the socket, which in turn caused the
code that mishandled the iovecs to be exercised, could unfortunately
not be readily duplicated in the erl_interface test suite.
