The RecordVal ctor refs the type arg via the MutableVal -> Val ctors,
so this line was double incrementing the type's ref count, but could
only decrement it once upon the Val's destruction.
These cases should be avoidable by fixing scripts where they occur and
they can also help catch typos that would lead to unintentional runtime
behavior.
Adding this already revealed several scripts where a field in an inlined
record was never removed after a code refactor.
* origin/topic/bernhard/input-logging-commmon-functions:
add the last of Robins suggestions (separate info-struct for constructors).
port memory leak fix from master
harmonize function naming
move AsciiInputOutput over to threading
and thinking about it, ascii-io doesn't need the separator
change constructors
and factor stuff out the input framework too.
factor out ascii input/output.
std::string accessors to escape_sequence functionality
intermediate commit - it has been over a month since I touched this...
I cleaned up the AsciiInputOutput class somewhat, including renaming
it to AsciiFormatter, renaming some of its methods, and turning the
static methods into members for consistency.
Closes#929.
* origin/topic/jsiwek/ticket-930:
Add a null value check in CompositeHash::ComputeHash.
Change reporter messages to more reliably print to stderr.
Closes#930.
* origin/topic/jsiwek/no-switch-fallthrough:
Add "fallthrough" keyword, require a flow statement to end case blocks.
Disable automatic case fallthrough in switch stmts. Addresses #754.
I've added a test for the error case where no break/fallthrough/return
is given.
Closes#754.
* origin/fastpath:
Fixing variable size issues (was uint, should be long) with http response code.
Revert "Trick for parallelizing input framework unit tests."
add opaque type-ignoring for the accept_unsupported_types input framework option.
Moved this functionality to be internal instead of in the script-layer
event handlers. The issue with the later is that bad things can happen
between the time a reporter event handler is dispatched and the time it
is executed, and if bro crashes in that time, the message may never be
seen/logged.
Addressed #930 (and revisits #836).
Since values for local variables are referenced by offset within a Frame
(not by identifier name), and event/hook handler bodies share a common
Frame, the value offsets for local variables in different handlers may
overlap. This meant locals in a handler without an initialization may
actually end up referring to the value of a previous handler's local
that has the same Frame offset. When executing the body, that can
possibly result in a type-conflict error or give give unexpected
results instead of a "use of uninitialized value" error.
This patch makes it so uninitialized locals do always refer to a null
value before executing the body of a event/hook handler, so that using
them without assigning a value within the body will connsistently give
a "use of uninitialized value" error.
Addresses #932.
Sadly there also seems to be another deadlock issue which I am currently
not really able to figure out - on shutdown sometimes (too often) the main
thread + all sqlite threads wait for semaphores or mutexes.
Case blocks in switch statements now must end in a break, return, or
fallthrough statement to give best mix of safety, readability, and
flexibility.
The new fallthrough keyword explicitly allows control to be passed to the
next case block in a switch statement.
Addresses #754.
Case bodies now don't require a "break" statement to prevent fallthrough
to case bodies below. Empty case bodies generate an error message at
parse-time to help indicate the absence of automatic fallthrough; to
associate multiple values with a case, use "case 1, 2:" instead of
"case 1: case 2:".
