Quick Q: Reusing a moved container?

By Adrien Hamelin | Apr 15, 2019 10:48 AM | Tags: intermediate c++11

Quick A: clear() to make sure and use it as normal.

Recently on SO:

Reusing a moved container?

From section 17.3.26 of the spec "valid but unspecified state":

an object state that is not specified except that the object’s invariants are met and operations on the object behave as specified for its type [ Example: If an object x of type std::vector<int> is in a valid but unspecified state, x.empty() can be called unconditionally, and x.front() can be called only if x.empty() returns false. —end example ]

Therefore, the object is live. You can perform any operation that does not require a precondition (unless you verify the precondition first).

clear, for example, has no preconditions. And it will return the object to a known state. So just clear it and use it as normal.

Report from the February 2019 ISO C++ meeting (Core Language working group)

by Jason Merrill

From the article:

The February 2019 ISO C++ meeting was held in Kailua-Kona, Hawaii. As usual, Red Hat sent three developers to the meeting: I attended in the Core Language working group, Jonathan Wakely in Library, and Thomas Rodgers in SG1 (parallelism and concurrency). The meeting went smoothly, although there was significant uncertainty at the beginning where we would end up. In the end, Modules and Coroutines were accepted into the C++20 draft, so now we have our work cut out for us nailing down the remaining loose corners. Here ar highlights from the meeting...

The Day I Fell in Love with Fuzzing--Chris Wellons

Do you know about it?

The Day I Fell in Love with Fuzzing

by Chris Wellons

From the article:

In 2007 I wrote a pair of modding tools, binitools, for a space trading and combat simulation game named Freelancer. The game stores its non-art assets in the format of “binary INI” files, or “BINI” files. The motivation for the binary format over traditional INI files was probably performance: it’s faster to load and read these files than it is to parse arbitrary text in INI format...
