Hi all,
Here's something that's been itching in me for a long time. Something I've
even (twice!) tried to fix. Both times my patch ended up so huge and
complicated for me that I had to give it and postpone the idea.
Put shortly: "conn->data considered bad". The association *from* a connection
object to a transfer object is bad, because it is fragile and error-prone due
to the fact that it can and will change very frequently for multiplexed
transfers.
A transfer can use one (or no) connection. A connection can have no, one or
very many transfers associated with it.
Conclusion: we should stop using 'conn->data' in libcurl
Status: there are 939 current uses of this pointer
Mission: reduce the use of this pointer, aiming to reach a point in the future
when we can remove it from the connection struct.
All this summed up in a wiki page:
