with either MBC_ABLK_SZ or MBC_FBLK_SZ in all cases when we already know
what kind of block it is.
|
|
A block larger than sbc_threshold can be allocated in MBC if the subsequent
"residue block" is smaller than min_block_size.
Solved by lowering sbc_threshold to ("hard limit" - min_block_size).
|
|
* Account for block header size in gc-sizes
* Also slow down growth to 20% instead of 25% when
size threshold is reached

HAVE_SUPER_ALIGNED_MB_CARRIERS is always true with mmap and thus
aligned bits is a constant and so is "page" size for mmap.

* Don't redfine ALIGN_BITS or ALIGNED_SIZE, the global defined MSEG_*
constants are just as good.

No allocator strategy is using customized carrier headers anyway.

To get a consistent naming scheme where
FBLK = Free block
ABLK = Allocated block
|
|
|
|
by making use of the new block header scheme to find the carrier header
and thereby the allocator.
|
|
Make use of type FreeBlkFtr_t
Rename GET_MB_CARRIER into BLK2MBC (like BLK2SBC)
Remove some unused macros
|
|
to allow realloc to determine block size (in MBC or SBC)
without having to read the footer of the previous block
that might be written to by concurrent thread.

Because of a forgotten "Fd", configuration information intended for
ct_master_log.html ended up being written to standard output.

* dgud/stdlib/proc_lib_hangs/OTP-9803:
stdlib: Monitor proc_lib:start'ed processes to avoid waiting forever
|
|
Monitor the spawned process in proc_lib:start/[3|4|5], so
that a proper error is returned, if the spawned process crashes
before proclib:init_ack/1 is sent.
Previously the calling process would hang forever or until specified
timeout. Start link catches these errors but start did not.
start now behaves as start_link if process traps exit.

|
|
Use ct:timetrap/1 instead of test_server:timetrap/1 for really long
test_cases.
Commontest sets up a default timetrap on 30 min, which is not cancelled
if testserver:timetrap called.

Before line numbers were included in exceptions (in R15), there were
parse transforms and macros that would keep the test_server_loc
process dictionary variable updated; therefore there is a mod_loc/1
function that will normalize the representation of locations.
Simplify the code as following:
* 'test_server_loc' should always contain a list with one or more
tuples. ({M,F} or {M,F,Line})
* At the beginning of each test case, set 'test_server_loc' to
[{Module,Func}] of the the currently executing test case.
* Stop updating 'test_server_loc', except when an exception occurs.
(It used to be updated when running 'init_per_testcase' and so on.)
* Remove the mod_loc/1 function.

Three pieces of information could be out of sync in testcase
supervisor process at the time when a timetrap occurred:
* test_server_loc (process dictionary) - may indicate that a
framework function is executing
* test_server_init_or_end_conf (process dictionary) - indicates whether
init_per_testcase or end_per_testcase is executing
* The current configuration (#st.config) - set using a synchronous
call
There could be in a crash in spawn_fw_call/7 because the current
configuration was not defined when it was expected to.
To avoid the problem, introduce set_tc_state/2 (and a corresponding
message) to allow setting both an indication what the testcase is
executing (e.g. init_per_testcase, framework call, and so on), and
the current configuration. Use only that information to handle
a timetrap timeout (and aborted testcase and the other reasons
for the testcase process to terminate). Completely remove
test_server_init_or_end_conf.

The Loc argument was use to determine the name of the currently
executing test case, in case that the M and F arguments did not
specify a test case.
Since a previous commit makes sure that the M and F arguments *are*
valied, we can eliminate the Loc argument.
|
|
The code is not actually shorter, but it avoids duplicating the code
for producing an error tuple when theres is no priv_dir tuple in
the config data.

Keeping all state as separate function arguments does not make it
easy to add more pieces of data to the state. Case in point is the
CurrConf argument where up to three separate items have been
shoehorned in.
Instead of the arguments, introduce a state record to hold all of the
different pieces of state (taking care to separate the former CurrConf
variable into separate fields in the record).
While at it, fix a bug. The name of the currently executing test
case (module and function) used to be stored in a tuple in the CurrConf
variable, and it would only be available after 'set_curr_conf' message
has been received. Depending on timing, it was possible in rare
circumstances for an EXIT signal to arrive before the 'set_curr_conf'
message. Avoid this problem by putting the current test case
name into the record from the beginning. That also means that we
can eliminate the workaround of getting the currently executing test case
from the stack trace using the get_mf/1.
