jinterface: fix bug in equality for OtpErlangFun
|
|
Arrays (here: md5 and freeVars) must not be compared with equals, which
is broken.

Fix a few javadoc errors

Arrays have no meaningful toString method, but one must use
Arrays.toString instead. The meaningless value would look for example
like "[C@16f0472", instead of "[2,4]".

Ensure all are "normal" versions according to the new version scheme
introduced in OTP 17.0
|
|
This is just a preparation to allow detection of older nodes
that do not understand maps (R16 and older).
|
|
to be: 116,Arity, K1,V1,K2,V2,...,Kn,Vn
instead of: 116,Arity, K1,K2,...,Kn, V1,V2,....,Vn
We think this will be better for future internal map structures
like HAMT. Would be bad if we need to iterate twice over HAMT
in term_to_binary, one for keys and one for values.

|
Let Maps be tested in the suite.
|
|
|
|
The API and implementation are simplistic, like for lists and tuples,
using arrays and without any connection to java.util.Map.

Add smoke tests

Smoke tests are meant to verify that a build of erlang has been successfull.

The test cases nc_SUITE:decompress_roundtrip and
nc_SUITE:compress_roundtrip fails on some machines with
OutOfMemoryException. This commit sets the max heap size for the jvm
to 256M in nc_SUITE in order to get around this.

In some cases when a test case fails, the erl_link_server process
(which is spawned by many test cases in jinterface_SUITE) does not
terminate. This causes the next test case to fail with a badarg as it
tries to register a new process with the same name. To avoid this,
erl_link_server, if it exists, is now killed in end_per_testcase.
Also, some compiler warnings are removed from jitu.erl.

Add quotes around classpath on windows.

* nk/jinterface_dont_compress_if_size_increased/OTP-10822:
jinterface, OtpOutputStream: add a write_compressed(object, level) method
jinterface: fix a memory leak
jinterface: new limited OutputStream implementation without the need to resize
jinterface: don't return compressed external term if bigger than uncompressed
jinterface: don't compress small erlang terms < 5 bytes
jinterface, OtpOutputStream: properly override the three write() methods to ensure our growth strategy
jinterface: fix typo in error message if encoding fails
jinterface: don't need another FilterOutputStream wrapper

Now that we use an own deflater, we can also allow the user to specify the compression level as in Erlang's term_to_binary/2.
|
|
after the first try to compress the value with a fixed buffer size, the deflater must be closed so that memory can be (instantly) reused
|
|
(saves memory re-allocations)
|
|
Now, OtpOutputStream#write_compressed() uses the same mechanism as erts_term_to_binary() in external.c: it tries to compress the given term into a buffer of the size of the uncompressed term and if this is not possible, i.e. the compression plus headers is bigger, it uses the uncompressed external term format instead.
|
|
Compression always has at least 5 bytes (the compressed tag + original size) so we can't get a smaller external term if the original term is already smaller than 5 bytes.
|
|
ensure our growth strategy
Previously, if code called e.g. write(byte[] b, int off, int len), the growth strategy of the parent class ByteArrayOutputStream was used.
|
|
|
|
DeflaterOutputStream is already an FilterOutputStream
|
|
Jinterface uses System.getProperty("user.home") to locate the user's home
and the cookie file. On Windows, the result might be different than the
value used by Erlang, which looks first to the HOMEDRIVE and HOMEPATH
variables.
The fix makes jinterface use the same logic.
