This will prevent crashes in ssh_file for public key types which have no passphrase option although being supported.
Also centralize host key checking to avoid code duplication. This was already done for user keys.
|
|
Also rename the corresponding testcase in ssh_options_SUITE and add logging.
|
|
No intentional api changes. Only to make the code less hard to read.

Spell 'Guidelines' in the title for applications with a capital G, in system/doc/design_principles/applications.xml.

Also fix erts_debug:get_internal_status(node_and_dist_references)
for catree to also search route node keys for offheap stuff.

Since we call them 'Directory Structure' and 'Development Environment' in the
title, this fits more into the title.

`beam_ssa_dead` can waste a lot of time trying to optimize
an unoptimizable `switch` instruction.
By being a little bit smarter when optimizing `switch` instructions,
the runtime for the beam_ssa_dead pass was reduced approximately by
half on my computer for this module:

The linear scan algorithm keeps unhandled intervals in two separate
lists: one for intervals with reserved registers and one for intervals
without reserved registers. When collecting the available free registers
all unhandled intervals with reserved registers must be checked for
overlap.
Unhandled intervals that had a preferred register were put into the
list of intervals with reserved registers, leading to a lot of
unecessary overlap checking if there were many intervals with
preferred registers. Changing the partition code to put intervals with
preferred registers into the general list of unhandled intervals will
reduce the compilation time if there are many preferred registers.
On my computer, this change reduced the time of the linear scan pass
from about 20 seconds down to about 0.5 seconds for this module:

The type analysis pass (`beam_ssa_type`) keeps the type information
for all variables that are in scope. For huge functions, the
`join_types/2` function could get really slow when joining two
maps with thousands of variables in each.
Use a conservative approach to discard type information for
variables only used once by a `br` or `switch` in the same
block as the variable is defined in.
This approach reduces the runtime for the `beam_ssa_type` pass
from a few minutes down to few seconds for this module:
https://github.com/aggelgian/cuter/blob/master/src/cuter_binlib.erl
Rejected approach: Calculate liveness information for all variables
and discard type information for any variable that would not be
used again. That turned out to not work because some optimizations
would invalidate the liveness (in particular, substitutions could
lengthen the lifetime for a variable). Trying to update the
liveness information when doing the optimizations would be tricky.
