Sometimes, the database is active but the cache isn't filled out, or
doesn't contain the module you want. This can come up especially when
msfconsole first starts and you are programmatically searching for
modules, for whatever reason.
This allows for falling back to the regular (slow) search in the event
no hits have been returned. It does not actually address the caching
problem seen in QA, but it's generally going to be Good Enough. Search
is getting overhauled Real Soon Now anyway.
[FixRM #7533]
::File.find did not return an Enumerable when not given a block in
1.8.7; instead it un-idiomatically just raised an exception. The
solution is just to give the block directly to .find instead of trying
to call #each on its return value.
[FixRM #7499]
Makes it work when using meterpreter. Because "quit" or "exit" in the
console ends up calling die() instead of falling through to whatever's
left in the file, a meterpreter session would never reach the code to
delete itself before this change.
[Fixes#38426061, #38097411]
Msf::Modules::Loader::Directory#read_module_content may calculate a non-existent
module_path that gets passed to File.open causing an Errno::ENOENT exception
to be raised when using the module cache with a module that has been
moved to a new path (as is the case that originally found this bug) or
deleted. Now, the exception is rescued and read_module_content returns
an empty string (''), which load_module detects with
module_content.empty? and returns earlier without attempting to module
eval the (empty) content.
As having Msf::Modules::Loader::Directory#read_module_content rescue the
exception, meant there was another place that needed to log and error
and store an error in Msf::ModuleManager#module_load_error_by_path, I
refactored the error reporting to call
Msf::Modules::Loader::Base#load_error, which handles writing to the log
and setting the Hash, so the error reporting is consistent across the
loaders.
The exception hierarchy was also refactored so that
namespace_module.metasploit_class now has an error raising counter-part:
namespace_module.metasploit_class! that can be used with
Msf::Modules::Loader::Base#load_error as it requires an exception, and
not just a string so the exception class, message, and backtrace can be
logged.
