Use 'unsigned:1' when we mean boolean options These options are all strictly boolean (true/false). Its easier to document this implicitly by making their storage type a single bit. There is no compelling memory space reduction reason for this change, it just makes the structure definition slightly more readable. Signed-off-by: Shawn O.

Always obtain fetch-pack arguments from struct fetch_pack_args Copying the arguments from a fetch_pack_args into static globals within the builtin-fetch-pack module is error-prone and may lead rise to cases where arguments supplied via the struct from the new fetch_pack() API may not be honored by the implementation. Here we reorganize all of the static globals into a single static struct fetch_pack_args instance and use memcpy() to move the data from the caller supplied structure into the globals before we execute our pack fetching implementation. This strategy is more robust to additions and deletions of properties. As keep_pack is a single bit we have also introduced lock_pack to mean not only download and store the packfile via index-pack but also to lock it against repacking by creating a .keep file when the packfile itself is stored. The caller must remove the .keep file when it is safe to do so. Signed-off-by: Shawn O.

Teach fetch-pack/upload-pack about --include-tag The new protocol extension "include-tag" allows the client side of the connection (fetch-pack) to request that the server side of the native git protocol (upload-pack / pack-objects) use --include-tag as it prepares the packfile, thus ensuring that an annotated tag object will be included in the resulting packfile if the object it refers to was also included into the packfile.

Smart fetch over HTTP: client side The git-remote-curl backend detects if the remote server supports the git-upload-pack service, and if so, runs git-fetch-pack locally in a pipe to generate the want/have commands. The advertisements from the server that were obtained during the discovery are passed into git-fetch-pack before the POST request starts, permitting server capability discovery and enablement. Common objects that are discovered are appended onto the request as have lines and are sent again on the next request. This allows the remote side to reinitialize its in-memory list of common objects during the next request. Because all requests are relatively short, below git-remote-curl's 1 MiB buffer limit, requests will use the standard Content-Length header and be valid HTTP/1.0 POST requests. This makes the fetch client more tolerant of proxy servers which don't support HTTP/1.1 or the chunked transfer encoding. Signed-off-by: Shawn O.

Reduce the number of connects when fetching This shares the connection between getting the remote ref list and getting objects in the first batch. (A second connection is still used to follow tags). When we do not fetch objects (i.e. either ls-remote disconnects after getting list of refs, or we decide we are already up-to-date), we clean up the connection properly; otherwise the connection is left open in need of cleaning up to avoid getting an error message from the remote end when ssh is used.
