2010-01-17Make "subtree" part more orthogonal to the rest of merge-recursive.Libravatar Junio C Hamano1-0/+1
This makes "subtree" more orthogonal to the rest of recursive merge, so that you can use subtree and ours/theirs features at the same time. For example, you can now say: git merge -s subtree -Xtheirs other to merge with "other" branch while shifting it up or down to match the shape of the tree of the current branch, and resolving conflicts favoring the changes "other" branch made over changes made in the current branch. It also allows the prefix used to shift the trees to be specified using the "-Xsubtree=$prefix" option. Giving an empty prefix tells the command to figure out how much to shift trees automatically as we have always done. "merge -s subtree" is the same as "merge -s recursive -Xsubtree=" (or "merge -s recursive -Xsubtree"). Based on an old patch done back in the days when git-merge was a script; Avery ported the script part to builtin-merge.c. Bugs in shift_tree() is mine.

bb1ae3f (commit: Show committer if automatic, 2008-05-04) added a logic to check both name and email were given explicitly by the end user, but it assumed that fmt_ident() is never called before git_default_user_config() is called, which was fragile. The former calls setup_ident() and fills the "default" name and email, so the check in the config parser would have mistakenly said both are given even if only user.name was provided. Make the logic more robust by keeping track of name and email separately. Signed-off-by: Junio C Hamano <gitster@pobox.com> Acked-by: Santi Béjar <santi@agolina.net>
2010-01-07unpack-trees.c: prepare for looking ahead in the indexLibravatar Junio C Hamano1-0/+2
This prepares but does not yet implement a look-ahead in the index entries when traverse-trees.c decides to give us tree entries in an order that does not match what is in the index. A case where a look-ahead in the index is necessary happens when merging branch B into branch A while the index matches the current branch A, using a tree O as their common ancestor, and these three trees looks like this: O A B t t t-i t-i t-i t-j t-j t/1 t/2 The traverse_trees() function gets "t", "t-i" and "t" from trees O, A and B first, and notices that A may have a matching "t" behind "t-i" and "t-j" (indeed it does), and tells A to give that entry instead. After unpacking blob "t" from tree B (as it hasn't changed since O in B and A removed it, it will result in its removal), it descends into directory "t/". The side that walked index in parallel to the tree traversal used to be implemented with one pointer, o->pos, that points at the next index entry to be processed. When this happens, the pointer o->pos still points at "t-i" that is the first entry. We should be able to skip "t-i" and "t-j" and locate "t/1" from the index while the recursive invocation of traverse_trees() walks and match entries found there, and later come back to process "t-i". While that look-ahead is not implemented yet, this adds a flag bit, CE_UNPACKED, to mark the entries in the index that has already been processed. o->pos pointer has been renamed to o->cache_bottom and it points at the first entry that may still need to be processed.

2010-01-03"reset --merge": fix unmerged caseLibravatar Junio C Hamano1-0/+1
Commit 9e8ecea (Add 'merge' mode to 'git reset', 2008-12-01) disallowed "git reset --merge" when there was unmerged entries. But it wished if unmerged entries were reset as if --hard (instead of --merge) has been used. This makes sense because all "mergy" operations makes sure that any path involved in the merge does not have local modifications before starting, so resetting such a path away won't lose any information. The previous commit changed the behavior of --merge to accept resetting unmerged entries if they are reset to a different state than HEAD, but it did not reset the changes in the work tree, leaving the conflict markers in the resulting file in the work tree. Fix it by doing three things: - Update the documentation to match the wish of original "reset --merge" better, namely, "An unmerged entry is a sign that the path didn't have any local modification and can be safely resetted to whatever the new HEAD records"; - Update read_index_unmerged(), which reads the index file into the cache while dropping any higher-stage entries down to stage #0, not to copy the object name from the higher stage entry. The code used to take the object name from the a stage entry ("base" if you happened to have stage #1, or "ours" if both sides added, etc.), which essentially meant that you are getting random results depending on what the merge did. The _only_ reason we want to keep a previously unmerged entry in the index at stage #0 is so that we don't forget the fact that we have corresponding file in the work tree in order to be able to remove it when the tree we are resetting to does not have the path. In order to differentiate such an entry from ordinary cache entry, the cache entry added by read_index_unmerged() is marked as CE_CONFLICTED. - Update merged_entry() and deleted_entry() so that they pay attention to cache entries marked as CE_CONFLICTED. They are previously unmerged entries, and the files in the work tree that correspond to them are resetted away by oneway_merge() to the version from the tree we are resetting to.

2009-12-25resolve-undo: teach "update-index --unresolve" to use resolve-undo infoLibravatar Junio C Hamano1-0/+1
The update-index plumbing command had a hacky --unresolve implementation that was written back in the days when merge was the only way for users to end up with higher stages in the index, and assumed that stage #2 must have come from HEAD, stage #3 from MERGE_HEAD and didn't bother to compute the stage #1 information. There were several issues with this approach: - These days, merge is not the only command, and conflicts coming from commands like cherry-pick, "am -3", etc. cannot be recreated by looking at MERGE_HEAD; - For a conflict that came from a merge that had renames, picking up the same path from MERGE_HEAD and HEAD wouldn't help recreating it, either; - It may have been Ok not to recreate stage #1 back when it was written, because "diff --ours/--theirs" were the only availble ways to review conflicts and they don't need stage #1 information. "diff --cc" that was invented much later is a lot more useful way but it needs stage #1. We can use resolve-undo information recorded in the index extension to solve all of these issues.

2009-12-25resolve-undo: "checkout -m path" uses resolve-undo informationLibravatar Junio C Hamano1-0/+1
Once you resolved conflicts by "git add path", you cannot recreate the conflicted state with "git checkout -m path", because you lost information from higher stages in the index when you resolved them. Since we record the necessary information in the resolve-undo index extension these days, we can reproduce the unmerged state in the index and check it out.

2009-12-25resolve-undo: record resolved conflicts in a new index extension sectionLibravatar Junio C Hamano1-0/+2
When resolving a conflict using "git add" to create a stage #0 entry, or "git rm" to remove entries at higher stages, remove_index_entry_at() function is eventually called to remove unmerged (i.e. higher stage) entries from the index. Introduce a "resolve_undo_info" structure and keep track of the removed cache entries, and save it in a new index extension section in the index_state. Operations like "read-tree -m", "merge", "checkout [-m] <branch>" and "reset" are signs that recorded information in the index is no longer necessary. The data is removed from the index extension when operations start; they may leave conflicted entries in the index, and later user actions like "git add" will record their conflicted states afresh.

2009-12-14ie_match_stat(): do not ignore skip-worktree bit with CE_MATCH_IGNORE_VALIDLibravatar Nguyễn Thái Ngọc Duy1-1/+3
Previously CE_MATCH_IGNORE_VALID flag is used by both valid and skip-worktree bits. While the two bits have similar behaviour, sharing this flag means "git update-index --really-refresh" will ignore skip-worktree while it should not. Instead another flag is introduced to ignore skip-worktree bit, CE_MATCH_IGNORE_VALID only applies to valid bit.

The function returns NULL if there is no suitable editor; the caller is expected to issue an error message when appropriate. launch_editor() uses git_editor() and gives the error message the same way as before when EDITOR is not set. "git var GIT_EDITOR" gives the editor name, or an error message when there is no appropriate one. "git var -l" gives GIT_EDITOR=name only if there is an appropriate editor.

2009-11-09http-backend: Protect GIT_PROJECT_ROOT from /../ requestsLibravatar Shawn O. Pearce1-0/+1
Eons ago HPA taught git-daemon how to protect itself from /../ attacks, which Junio brought back into service in d79374c7b58d ("daemon.c and path.enter_repo(): revamp path validation"). I did not carry this into git-http-backend as originally we relied only upon PATH_TRANSLATED, and assumed the HTTP server had done its access control checks to validate the resolved path was within a directory permitting access from the remote client. This would usually be sufficient to protect a server from requests for its /etc/passwd file by http://host/smart/../etc/passwd sorts of URLs. However in 917adc036086 Mark Lodato added GIT_PROJECT_ROOT as an additional method of configuring the CGI. When this environment variable is used the web server does not generate the final access path and therefore may blindly pass through "/../etc/passwd" in PATH_INFO under the assumption that "/../" might have special meaning to the invoked CGI. Instead of permitting these sorts of malformed path requests, we now reject them back at the client, with an error message for the server log. This matches git-daemon behavior.

2009-10-19Introduce commit notesLibravatar Johannes Schindelin1-0/+4
Commit notes are blobs which are shown together with the commit message. These blobs are taken from the notes ref, which you can configure by the config variable core.notesRef, which in turn can be overridden by the environment variable GIT_NOTES_REF. The notes ref is a branch which contains "files" whose names are the names of the corresponding commits (i.e. the SHA-1). The rationale for putting this information into a ref is this: we want to be able to fetch and possibly union-merge the notes, maybe even look at the date when a note was introduced, and we want to store them efficiently together with the other objects. This patch has been improved by the following contributions: - Thomas Rast: fix core.notesRef documentation - Tor Arne Vestbø: fix printing of multi-line notes - Alex Riesen: Using char array instead of char pointer costs less BSS - Johan Herland: Plug leak when msg is good, but msglen or type causes return Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Tor Arne Vestbø <tavestbo@trolltech.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com> get_commit_notes(): Plug memory leak when 'if' triggers, but not because of read_sha1_file() failure
2009-10-18"checkout A...B" switches to the merge base between A and BLibravatar Junio C Hamano1-0/+1
When flipping commits around on topic branches, I often end up doing this sequence: * Run "log --oneline next..jc/frotz" to find out the first commit on 'jc/frotz' branch not yet merged to 'next'; * Run "checkout $that_commit^" to detach HEAD to the parent of it; * Rebuild the series on top of that commit; and * "show-branch jc/frotz HEAD" and "diff jc/frotz HEAD" to verify. Introduce a new syntax to "git checkout" to name the commit to switch to, to make the first two steps easier. When the branch to switch to is specified as A...B (you can omit either A or B but not both, and HEAD is used instead of the omitted side), the merge base between these two commits are computed, and if there is one unique one, we detach the HEAD at that commit. With this, I can say "checkout next...jc/frotz". Signed-off-by: Junio C Hamano <gitster@pobox.com>

Since the mtimes are renewed, those dangling objects cannot be pruned by "git gc --prune", even if they would have been old enough for pruning in the original repository. Instead, preserve mtime during copy. "git gc --prune" will then work in the clone just like it did in the original.

2009-09-13use write_str_in_full helper to avoid literal string lengthsLibravatar Jim Meyering1-2/+7
In 2d14d65 (Use a clearer style to issue commands to remote helpers, 2009-09-03) I happened to notice two changes like this: - write_in_full(helper->in, "list\n", 5); + + strbuf_addstr(&buf, "list\n"); + write_in_full(helper->in, buf.buf, buf.len); + strbuf_reset(&buf); IMHO, it would be better to define a new function, static inline ssize_t write_str_in_full(int fd, const char *str) { return write_in_full(fd, str, strlen(str)); } and then use it like this: - strbuf_addstr(&buf, "list\n"); - write_in_full(helper->in, buf.buf, buf.len); - strbuf_reset(&buf); + write_str_in_full(helper->in, "list\n"); Thus not requiring the added allocation, and still avoiding the maintenance risk of literal string lengths. These days, compilers are good enough that strlen("literal") imposes no run-time cost. Transformed via this: perl -pi -e \ 's/write_in_full\((.*?), (".*?"), \d+\)/write_str_in_full($1, $2)/'\ $(git grep -l 'write_in_full.*"') Signed-off-by: Jim Meyering <meyering@redhat.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-09-11push: make non-fast-forward help message configurableLibravatar Jeff King1-0/+1
This message is designed to help new users understand what has happened when refs fail to push. However, it does not help experienced users at all, and significantly clutters the output, frequently dwarfing the regular status table and making it harder to see. This patch introduces a general configuration mechanism for optional messages, with this push message as the first example.

2009-09-05core.whitespace: split trailing-space into blank-at-{eol,eof}Libravatar Junio C Hamano1-2/+3
People who configured trailing-space depended on it to catch both extra white space at the end of line, and extra blank lines at the end of file. Earlier attempt to introduce only blank-at-eof gave them an escape hatch to keep the old behaviour, but it is a regression until they explicitly specify the new error class. This introduces a blank-at-eol that only catches extra white space at the end of line, and makes the traditional trailing-space a convenient synonym to catch both blank-at-eol and blank-at-eof. This way, people who used trailing-space continue to catch both classes of errors. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-09-04apply --whitespace=warn/error: diagnose blank at EOFLibravatar Junio C Hamano1-1/+2
"git apply" strips new blank lines at EOF under --whitespace=fix option, but neigher --whitespace=warn nor --whitespace=error paid any attention to these errors. Introduce a new whitespace error class, blank-at-eof, to make the whitespace error handling more consistent. The patch adds a new "linenr" field to the struct fragment in order to record which line the hunk started in the input file, but this is needed solely for reporting purposes. The detection of this class of whitespace errors cannot be done while parsing a patch like we do for all the other classes of whitespace errors. It instead has to wait until we find where to apply the hunk, but at that point, we do not have an access to the original line number in the input file anymore, hence the new field. Depending on your point of view, this may be a bugfix that makes warn and error in line with fix. Or you could call it a new feature. The line between them is somewhat fuzzy in this case. Strictly speaking, triggering more errors than before is a change in behaviour that is not backward compatible, even though the reason for the change is because the code was not checking for an error that it should have. People who do not want added blank lines at EOF to trigger an error can disable the new error class. Signed-off-by: Junio C Hamano <gitster@pobox.com>
