Rename got-http helper to got-fetch-http to match naming scheme. We aren't planning to support sending anyway. ok stsp@

Add initial read-only http fetch support using a got-http helper. Currently we only support the smart protocol with a limited feature set. ok stsp@ tobhe@

plug a memory leak in 'got blame' The leak is present in got_privsep_recv_traversed_commits. There is an edge case where it receives consecutive imsgs. The first behaves as normal and we got_object_id_dup the last commit id for changed_commit_id. The following imsg(s) then still allocates the last commit id, leaking the one(s) prior allocated. Patch by Kyle Ackerman

fix GOT_IMSG_COMMIT_TRAVERSAL_REQUEST The sending and receiving side are sending the data differently. It works now by chance since a struct got_object_id is "just" a SHA1_DIGEST_LENGTH sized buffer, but will break in the future. Furthermore, the structure of the data as described in got_lib_privsep.h is not respected, as the path_len field is not transmitted. Change it to send/receive a whole struct got_object_id, the path without the NUL and the proper length. (The path is also actually mandatory, so assert it too.) improvements + ok stsp@

use struct got_object_id instead of sha1 digest in a few imsg change got_img_commit_painting_request, got_imsg_tag_object and the data of GOT_IMSG_TRAVERSED_COMMITS not to copy the sha1 digest to the imsg buffer and then from it to a new struct got_object_id but send directly the whole struct. ok stsp@

got: further fetch tweaks to prevent unintended fetches Implement stsp's suggestion to only fetch remote's HEAD if the symref refs/remote/*/HEAD exists, and its target no longer matches the remote HEAD. This ensures users tracking a project won't miss a change in HEAD, while also fixing the issue reported by naddy where HEAD was fetched by default even though a specific, potentially less active, branch is cloned, resulting in a repository with more commits than necessary. In addition, unless 'got fetch -b <branch>' is used, the remote HEAD branch will be fetched if branches are not set in got.conf and there is no work tree to ascertain a branch, or said branches are not found on the server. ok stsp@

special case 'got fetch -b <branch>' to only fetch <branch> As discussed on irc, this drops the implicit remote HEAD fetch when -b is used. got.1 has been updated to make the new fetch behaviour clear. ok stsp@

fix interaction of 'got fetch -b', got.conf, and work tree Without branches in got.conf for a remote, and without -b/-R options, the fallback to HEAD would only work when not invoked in a work tree. With this fix 'got fetch' should behave as described in the man page. The -b option now overrides both got.conf and the fallback to the work tree's branch. And fallback to HEAD works as expected when invoked in a repository. Also, do not strictly require remote repositories to provide a branch from the refs/heads/ namespace. In such cases users should be able to use -R to select something to fetch. ok jamsek

got-read-gitconfig: send key-value pairs for extensions Most extension allow only for a boolean value so the current behaviour of just sending the extension with a trueish value is fine. However, some extensions that we could eventually support (like "objectformat") have a string value. This is a preparatory step towards that. ok stsp@

move declaration of got_privsep_child out of got_lib_privsep.h This declaration is the only reason why got_lib_privsep.h must be included in order to use got_lib_repository.h. Moving this declaration will allow for cleaning up unnecessary includes of got_lib_privsep.h.
