From 454e2025a933593fd751475b59cc014887b4df6d Mon Sep 17 00:00:00 2001 From: Jay Soffian Date: Wed, 25 Feb 2009 03:32:11 -0500 Subject: move duplicated get_local_heads() to remote.c get_local_heads() appears to have been copied from builtin-send-pack.c to http-push.c via cut and paste. This patch moves the function and its helper one_local_ref() to remote.c. The two copies of one_local_ref() were not identical. I used the more recent version from builtin-send-pack.c after confirming with Jeff King that it was an oversight that commit 30affa1e did not update both copies.

You may notice that there is a remote struct that only contains the url from the repo struct. This struct is a temporary fix for a larger issue, but gets http authentication via prompts out the door, and keeps users from having to store passwords in plain text files.

This patch adds an ioctl callback, which should be usable on older curl versions (since 7.12.3) than the seek callback (introduced in curl 7.18.0). Some HTTP servers (such as Apache) give an 401 error reply immediately after receiving the headers (so no data has been read from the read buffers, and thus no rewinding is needed), but other servers (such as Lighttpd) only replies after the whole request has been sent and all data has been read from the read buffers, making rewinding necessary.
