When we create an http active_request_slot, we can set its "results" pointer back to local storage. The http code will fill in the details of how the request went, and we can access those details even after the slot has been cleaned up. Commit 8809703 (http: factor out http error code handling) switched us from accessing our local results struct directly to accessing it via the "results" pointer of the slot. That means we're accessing the slot after it has been marked as finished, defeating the whole purpose of keeping the results storage separate. Most of the time this doesn't matter, as finishing the slot does not actually clean up the pointer. However, when using curl's multi interface with the dumb-http revision walker, we might actually start a new request before handing control back to the original caller. In that case, we may reuse the slot, zeroing its results pointer, and leading the original caller to segfault while looking for its results inside the slot. Instead, we need to pass a pointer to our local results storage to the handle_curl_result function, rather than relying on the pointer in the slot struct. This matches what the original code did before the refactoring (which did not use a separate function, and therefore just accessed the results struct directly).

GIT - the stupid content tracker
////////////////////////////////////////////////////////////////
"git" can mean anything, depending on your mood.
- random three-letter combination that is pronounceable, and not
actually used by any common UNIX command. The fact that it is a
mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the
dictionary of slang.
- "global information tracker": you're in a good mood, and it actually
works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.
Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.
Please read the file INSTALL for installation instructions.
See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".
CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).
Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.
The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org (read
Documentation/SubmittingPatches for instructions on patch submission).
To subscribe to the list, send an email with just "subscribe git" in
the body to majordomo@vger.kernel.org. The mailing list archives are
available at http://marc.theaimsgroup.com/?l=git and other archival
sites.
The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
