dialyzer: Correct byte_size() and comparisons
|
|
The argument of byte_size() is a bitstring().
The code in erl_bif_types that finds cases where comparisons always
return true or false is corrected when it comes to maps and bit
strings.

[James Fish:]
Dialyzer always asserts that files and directories passed in its
options exist. Therefore it is not possible to remove a beam/module
from a PLT when the beam file no longer exists. Dialyzer should not to
check files exist on disk when removing from the PLT.

Speed up supervisor:count_children/1 for simple_one_for_one
supervisors. This is achieved by avoiding looping through all the
child process and verifying that each one is alive.
For a supervisor with 100,000 'temporary' children the count-time will
drop from approx 25ms to about 0.005ms.
For a supervisor with 100,000 'permanent' or 'transient' children the
count-time will drop from approx 30ms to about 0.005ms.
This avoids having the supervisor block for an extended period while
the count takes place. Under normal circumstances the accuracy of the
result should also improve since the duration is too short for many
processes to die during the count.

This function is used by release_handler during upgrade. This was
earlier implemented in the release_handler, but it required a copy og
the definition of the supervisor's internal state, which caused
problems when this state was updated.

Internally in the v3_core pass, an #imatch{} record represents
a match expression:
Pattern = Expression
If Pattern is a single, unbound variable, #imatch{} will be
rewritten to #iset{}; otherwise it will be rewritten to #icase{}.
To determine how #imatch{} should be translated, the pattern is
processed using upattern/3. The return value from upattern/3 is thrown
away (after having been used for determing how the #imatch{} record
should be translated).
That means that every pattern in an #imatch{} is processed twice,
which is wasteful.
We can easily avoid the double processing of patterns by
introducing a new helper function that determines whether the
pattern is a new variable.
