The trap frame allocation wrappers occasionally call the garbage
collector, even though built-in functions are not supposed to.
On non-{x86,amd64} platforms, HiPE was optimising the BIF wrapper
interface on the basis that BIFs do not GC. So, when
hipe_reserve_beam_trap_frame called the garbage collector, the state in
the PCB was stale and corruption happened.
Now, these particular BIFs are reclassified as GC BIFs.
Unfortunately, in order to do that we needed to introduce a
gc_bif_interface_3 macro in every hipe_$ARCH_bifs.m4 file.
|
|
An easy source of tricky bugs is to start calling the garbage collector
from a built-in function without adding that bif to hipe_bif_list.m4.
With this change we, in the debug build, keep track of whether the
canonical stack and heap pointers are stored in the PCB or in
registers/stack, allowing us to catch this class of mistakes with an
assertion.

Any exceptions at this point would be of class error, not exit.

When the compiler fails to write an output file, it used to just print
"error writing file". With this change, it also prints the error
reason:
$ echo "-module(foo)." > foo.erl
$ chmod -w .
$ erlc foo.erl
/tmp/bar/foo.bea#: error writing file: permission denied

Symptom: open_port() succeeds, port program never starts but instead
seem to terminate with exit_status 150 (EINVAL+128).
When: If the command payload buffer (including the entire environment)
for the port program is between 1 to 4 bytes above the pipe capacity,
which is 65536 bytes on newer Linux, but can be as low as 4096 on older
32-bit Linux.
Since: OTP-19.0-rc1.

The input for a call to compile:(noenv_)forms/2 can also be a cerl
module (useful e.g. to resume with 'from_core' after a 'to_core'
compilation).
Internal representations used for 'from_asm' and 'from_beam'
compilation can also be valid, but have no relevant types defined.

[ct test] Catch call to ssh:start/0
[sasl test] Do GC before measuring and comparing time
[sasl test] Give some time and try again if nodes are not synched
|

The ssh application is not installed on all test hosts. Catching the
call to ssh:start/0 allows the the netconf tests to be nicely skipped
if ssh does not exist.

release_handler_SUITE:otp_9395_*_many_mods sometimes fail on slow
machines. This commit adds an explicit GC before each
'install_release' so GC during test is avoided.
|

release_handler_SUITE:upgrade_gg (global group) sometimes fails on
slow machines. This commit re-tries five times before giving up.
