If we fail to parse out any functions from erlang.xml, make sure
that we fail.

The autoimport_SUITE:autoimport/1 test case would interpret
data type definitions as function calls. Fix this by skipping
to the <funcs> tag before starting to collect function names.

* bjorn/erts/fix-erlc_SUITE-arg_overflow:
erlc_SUITE: Fix arg_overflow/1 test case
|
|
|
|
In commit be8759e68b337524c056b8bb757ea68c9996d863, a buffer overflow
was fixed in erlc and the erlc_SUITE:arg_overflow/1 test case was
added. That test cases invokes erlc with 10000 -D options, which will
result in 'erl' being invoked with more than 30000 arguments.
On some platforms, the test case will fail for the wrong reason:
* 64-bit Linux kernels before 2.6.23 limit the number of arguments in
an excvp() call to 16383. (See "Number of arguments and maximum length
of one argument" in http://www.in-ulm.de/~mascheck/various/argmax/.)
* The command shell in Windows limits the size of the command line to
8191 characters.
Depending on the platform, pass a different number of -D options
to erlc. Since the size of the options does not matter for this
test case, make the options as short as possible by generating
numbers in base 36.

The functions zlib:deflateSetDictionary/2 and zlib:inflateSetDictionary/2
accept iodata() as Dictionary.
The functions zlib:crc32/2,3, zlib:adler32/2,3, zlib:compress/1,
zlib:uncompress/1, zlib:zip/1, and zlib:unzip/1 accept iodata() as
data.

In 64bits machines the Sint type has a size of 8 bytes,
while on 32bits machines it has a 4 bytes size.
enif_compare was ignoring this and therefore returning
incorrect values when the result of the CMP function
(which returns a Sint value) doesn't fit in 4 bytes.
For example, passing the operands -1294536544000 and
-1178704800000 to enif_compare would trigger the bug.

This BIF's second parameter is a list of options.
Currently the only allowed option is {minor_version, Version}
where version is either 0 (default) or 1.

Add erlang:check_old_code/1 to quickly check whether a module
has old code. If there is no old code, there is no need to call
erlang:check_process_code/2 for all processes, which will save
some time if there are many processes.
|
|
There is no need to suspend the process if the module has no old
code. Measurements show that this change will make
erlang:check_process_code/2 in an SMP emulator about four times
faster if the module has no old code.

Use a union for pointer type conversion to avoid compiler warnings
about strict-aliasing violations with gcc-4.1. gcc >= 4.2 does not
emit the warning.
TODO: Reconsider use of union once gcc-4.1 is obsolete?

We discovered that if a single Erlang process tried to grow above 32
GB (i.e., more 64-bit words than can be counted by a 32-bit number),
the VM failed to find the next larger heap size, even though there
were plenty more heap sizes left to pick from and even though we had a
lot more memory available on the machine. (Obviously, this is only
applicable on 64-bit Erlang.)
It turned out to be due to some 'int' variables in the heap resizing
parts of erl_gc.c not being properly updated to 'Uint' or 'Sint'. Once
that was fixed, I got segfaults instead as soon as the heap got larger
than 2^32 words, due to even more 'int' declarations in the same file,
but now in the GC code.
After fixing this as well, I successfully ran an Erlang node in which
a single Erlang process had a heap so large that I'm not at liberty to
divulge the exact size, but I think the scientific term is
"humongous", and I'm confident that there are no further immediate
problems with very very large individual process heaps.
