* jk/robustify-parse-commit: checkout: do not die when leaving broken detached HEAD use parse_commit_or_die instead of custom message use parse_commit_or_die instead of segfaulting assume parse_commit checks for NULL commit assume parse_commit checks commit->object.parsed log_tree_diff: die when we fail to parse a commit
2013-10-24use parse_commit_or_die instead of custom messageLibravatar Jeff King1-2/+1
Many calls to parse_commit detect errors and die. In some cases, the custom error messages are more useful than what parse_commit_or_die could produce, because they give some context, like which ref the commit came from. Some, however, just say "invalid commit". Let's convert the latter to use parse_commit_or_die; its message is slightly more informative, and it makes the error more consistent throughout git.

2013-08-28shallow: add setup_temporary_shallow()Libravatar Nguyễn Thái Ngọc Duy1-0/+23
This function is like setup_alternate_shallow() except that it does not lock $GIT_DIR/shallow. It is supposed to be used when a program generates temporary shallow for use by another program, then throw the shallow file away.

2013-08-28shallow: only add shallow graft points to new shallow fileLibravatar Nguyễn Thái Ngọc Duy1-0/+2
for_each_commit_graft() goes through all graft points, and shallow boundaries are just one special kind of grafting. If $GIT_DIR/shallow and $GIT_DIR/info/grafts are both present, write_shallow_commits() may catch both sets, accidentally turning some graft points to shallow boundaries. Don't do that.

2013-07-15upload-pack: remove a piece of dead codeLibravatar Matthijs Kooijman1-11/+6
Commit 682c7d2 (upload-pack: fix off-by-one depth calculation in shallow clone) introduced a new check in get_shallow_commits to decide when to stop traversing the history and mark the current commit as a shallow root. With this new check in place, the old check can no longer be true, since the first check always fires first. This commit removes that check, making the code a bit more simple again.

2013-05-28fetch-pack: prepare updated shallow file before fetching the packLibravatar Nguyễn Thái Ngọc Duy1-2/+40
index-pack --strict looks up and follows parent commits. If shallow information is not ready by the time index-pack is run, index-pack may be led to non-existent objects. Make fetch-pack save shallow file to disk before invoking index-pack. git learns new global option --shallow-file to pass on the alternate shallow file path. Undocumented (and not even support --shallow-file= syntax) because it's unlikely to be used again elsewhere.

2013-01-11upload-pack: fix off-by-one depth calculation in shallow cloneLibravatar Nguyễn Thái Ngọc Duy1-1/+7
get_shallow_commits() is used to determine the cut points at a given depth (i.e. the number of commits in a chain that the user likes to get). However we count current depth up to the commit "commit" but we do the cutting at its parents (i.e. current depth + 1). This makes upload-pack always return one commit more than requested. This patch fixes it. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-06-07War on whitespaceLibravatar Junio C Hamano1-1/+0
This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

2006-11-24Shallow clone: do not ignore shallowness when following tagsLibravatar Alexandre Julliard1-1/+2
Tags should be considered when truncating the commit list. The patch below fixes it, and fetches the right number of commits for each tag. However the correct fix is probably to not fetch historical tags at all. Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-11-24support fetching into a shallow repositoryLibravatar Johannes Schindelin1-0/+97
A shallow commit is a commit which has parents, which in turn are "grafted away", i.e. the commit appears as if it were a root. Since these shallow commits should not be edited by the user, but only by core git, they are recorded in the file $GIT_DIR/shallow. A repository containing shallow commits is called shallow. The advantage of a shallow repository is that even if the upstream contains lots of history, your local (shallow) repository needs not occupy much disk space. The disadvantage is that you might miss a merge base when pulling some remote branch. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
