"git pull --rebase=interactive" learned "i" as a short-hand for "interactive". * js/pull-rebase-type-shorthand: pull --rebase=<type>: allow single-letter abbreviations for the type

2018-08-17Merge branch 'en/abort-df-conflict-fixes'Libravatar Junio C Hamano3-4/+123
"git merge --abort" etc. did not clean things up properly when there were conflicted entries in the index in certain order that are involved in D/F conflicts. This has been corrected. * en/abort-df-conflict-fixes: read-cache: fix directory/file conflict handling in read_index_unmerged() t1015: demonstrate directory/file conflict recovery failures
2018-08-17Merge branch 'mk/http-backend-content-length'Libravatar Junio C Hamano2-0/+193
The http-backend (used for smart-http transport) used to slurp the whole input until EOF, without paying attention to CONTENT_LENGTH that is supplied in the environment and instead expecting the Web server to close the input stream. This has been fixed. * mk/http-backend-content-length: t5562: avoid non-portable "export FOO=bar" construct http-backend: respect CONTENT_LENGTH for receive-pack http-backend: respect CONTENT_LENGTH as specified by rfc3875 http-backend: cleanup writing to child process

2018-08-17Merge branch 'jt/refspec-dwim-precedence-fix'Libravatar Junio C Hamano1-0/+35
"git fetch $there refs/heads/s" ought to fetch the tip of the branch 's', but when "refs/heads/refs/heads/s", i.e. a branch whose name is "refs/heads/s" exists at the same time, fetched that one instead by mistake. This has been corrected to honor the usual disambiguation rules for abbreviated refnames. * jt/refspec-dwim-precedence-fix: remote: make refspec follow the same disambiguation rule as local refs
2018-08-17Merge branch 'jk/merge-subtree-heuristics'Libravatar Junio C Hamano1-0/+28

2018-08-15Merge branch 'en/merge-recursive-skip-fix'Libravatar Junio C Hamano1-0/+13
When the sparse checkout feature is in use, "git cherry-pick" and other mergy operations lost the skip_worktree bit when a path that is excluded from checkout requires content level merge, which is resolved as the same as the HEAD version, without materializing the merge result in the working tree, which made the path appear as deleted. This has been corrected by preserving the skip_worktree bit (and not materializing the file in the working tree). * en/merge-recursive-skip-fix: merge-recursive: preserve skip_worktree bit when necessary t3507: add a testcase showing failure with sparse checkout
2018-08-15Merge branch 'jt/tag-following-with-proto-v2-fix'Libravatar Junio C Hamano1-3/+68
The wire-protocol v2 relies on the client to send "ref prefixes" to limit the bandwidth spent on the initial ref advertisement. "git fetch $remote branch:branch" that asks tags that point into the history leading to the "branch" automatically followed sent to narrow prefix and broke the tag following, which has been fixed. * jt/tag-following-with-proto-v2-fix: fetch: send "refs/tags/" prefix upon CLI refspecs t5702: test fetch with multiple refspecs at a time

2018-08-06pull --rebase=<type>: allow single-letter abbreviations for the typeLibravatar Johannes Schindelin1-0/+12
Git for Windows' original 4aa8b8c8283 (Teach 'git pull' to handle --rebase=interactive, 2011-10-21) had support for the very convenient abbreviation git pull --rebase=i which was later lost when it was ported to the builtin `git pull`, and it was not introduced before the patch eventually made it into Git as f5eb87b98dd (pull: allow interactive rebase with --rebase=interactive, 2016-01-13). However, it is *really* a useful short hand for the occasional rebasing pull on branches that do not usually want to be rebased. So let's reintroduce this convenience, at long last.

Add a server-side knob to skip commits in exponential/fibbonacci stride in an attempt to cover wider swath of history with a smaller number of iterations, potentially accepting a larger packfile transfer, instead of going back one commit a time during common ancestor discovery during the "git fetch" transaction. * jt/fetch-negotiator-skipping: negotiator/skipping: skip commits during fetch
2018-08-02Merge branch 'bc/sequencer-export-work-tree-as-well'Libravatar Junio C Hamano1-0/+9
"git rebase" started exporting GIT_DIR environment variable and exposing it to hook scripts when part of it got rewritten in C. Instead of matching the old scripted Porcelains' behaviour, compensate by also exporting GIT_WORK_TREE environment as well to lessen the damage. This can harm existing hooks that want to operate on different repository, but the current behaviour is already broken for them anyway. * bc/sequencer-export-work-tree-as-well: sequencer: pass absolute GIT_WORK_TREE to exec commands

2018-08-02score_trees(): fix iteration over trees with missing entriesLibravatar Jeff King1-0/+28
In score_trees(), we walk over two sorted trees to find which entries are missing or have different content between the two. So if we have two trees with these entries: one two --- --- a a b c c d we'd expect the loop to: - compare "a" to "a" - compare "b" to "c"; because these are sorted lists, we know that the second tree does not have "b" - compare "c" to "c" - compare "d" to end-of-list; we know that the first tree does not have "d" And prior to d8febde370 (match-trees: simplify score_trees() using tree_entry(), 2013-03-24) that worked. But after that commit, we mistakenly increment the tree pointers for every loop iteration, even when we've processed the entry for only one side. As a result, we end up doing this: - compare "a" to "a" - compare "b" to "c"; we know that we do not have "b", but we still increment both tree pointers; at this point we're out of sync and all further comparisons are wrong - compare "c" to "d" and mistakenly claim that the second tree does not have "c" - exit the loop, mistakenly not realizing that the first tree does not have "d" So contrary to the claim in d8febde370, we really do need to manually use update_tree_entry(), because advancing the tree pointer depends on the entry comparison. That means we must stop using tree_entry() to access each entry, since it auto-advances the pointer. Instead: - we'll use tree_desc.size directly to know if there's anything left to look at (which is what tree_entry() was doing under the hood) - rather than do an extra struct assignment to "e1" and "e2", we can just access the "entry" field of tree_desc directly That makes us a little more intimate with the tree_desc code, but that's not uncommon for its callers. The included test shows off the bug by adding a new entry "bar.t", which sorts early in the tree and de-syncs the comparison for "foo.t", which comes after.

2018-08-02remote: make refspec follow the same disambiguation rule as local refsLibravatar Junio C Hamano1-0/+35
When matching a non-wildcard LHS of a refspec against a list of refs, find_ref_by_name_abbrev() returns the first ref that matches using any DWIM rules used by refname_match() in refs.c, even if a better match occurs later in the list of refs. This causes unexpected behavior when (for example) fetching using the refspec "refs/heads/s:<something>" from a remote with both "refs/heads/refs/heads/s" and "refs/heads/s"; even if the former was inadvertently created, one would still expect the latter to be fetched. Similarly, when both a tag T and a branch T exist, fetching T should favor the tag, just like how local refname disambiguation rule works. But because the code walks over ls-remote output from the remote, which happens to be sorted in alphabetical order and has refs/heads/T before refs/tags/T, a request to fetch T is (mis)interpreted as fetching refs/heads/T. Update refname_match(), all of whose current callers care only if it returns non-zero (i.e. matches) to see if an abbreviated name can mean the full name being tested, so that it returns a positive integer whose magnitude can be used to tell the precedence, and fix the find_ref_by_name_abbrev() function not to stop at the first match but find the match with the highest precedence. This is based on an earlier work, which special cased only the exact matches, by Jonathan Tan.
