1f5ad6b t: use sane_unset instead of unset Change several tests to use the sane_unset function introduced in v1.7.3.1-35-g00648ba instead of the built-in unset function. This fixes a failure I was having on t9130-git-svn-authors-file.sh on Solaris, and prevents several other issues from occurring.

d24fbca Remove Git's support for smoke testing I'm no longer running the Git smoke testing service at smoke.git.nix.is due to Smolder being a fragile piece of software not having time to follow through on making it easy for third parties to run and submit their own smoke tests. So remove the support in Git for sending smoke tests to smoke.git.nix.is, it's still easy to modify the test suite to submit smokes somewhere else.

6d62c98 Makefile: Change the default compiler from "gcc" to "cc" Ever since the very first commit to git.git we've been setting CC to "gcc". Presumably this is behavior that Linus copied from the Linux Makefile. However unlike Linux Git is written in ANSI C and supports a multitude of compilers, including Clang, Sun Studio, xlc etc. On my Linux box "cc" is a symlink to clang, and on a Solaris box I have access to "cc" is Sun Studio's CC. Both of these are perfectly capable of compiling Git, and it's annoying to have to specify CC=cc on the command-line when compiling Git when that's the default behavior of most other portable programs. So change the default to "cc". Users who want to compile with GCC can still add "CC=gcc" to the make(1) command-line, but those users who don't have GCC as their "cc" will see expected behavior, and as a bonus we'll be more likely to smoke out new compilation warnings from our distributors since they'll me using a more varied set of compilers by default.

31fd8d7 tag: do not show non-tag contents with "-n" "git tag -n" did not check the type of the object it is reading the top n lines from. At least, avoid showing the beginning of trees and blobs when dealing with lightweight tags that point at them. As the payload of a tag and a commit look similar in that they both start with a header block, which is skipped for the purpose of "-n" output, followed by human readable text, allow the message of commit objects to be shown just like the contents of tag objects. This avoids regression for people who have been using "tag -n" to show the log messages of commits that are pointed at by lightweight tags. Test script is from Jeff King.

701825d add -e: do not show difference in a submodule that is merely dirty When the HEAD of the submodule matches what is recorded in the index of the superproject, and it has local changes or untracked files, the patch offered by "git add -e" for editing shows a diff like this: diff --git a/submodule b/submodule <header> -deadbeef... +deadbeef...-dirty Because applying such a patch has no effect to the index, this is a useless noise. Generate the patch with IGNORE_DIRTY_SUBMODULES flag to prevent such a change from getting reported. This patch also loses the "-dirty" suffix from the output when the HEAD of the submodule is different from what is in the index of the superproject. As such dirtiness expressed by the suffix does not affect the result of the patch application at all, there is no information lost if we remove it. The user could still run "git status" before "git add -e" if s/he cares about the dirtiness.

fb630e0 tag: die when listing missing or corrupt objects We don't usually bother looking at tagged objects at all when listing. However, if "-n" is specified, we open the objects to read the annotations of the tags. If we fail to read an object, or if the object has zero length, we simply silently return. The first case is an indication of a broken or corrupt repo, and we should notify the user of the error. The second case is OK to silently ignore; however, the existing code leaked the buffer returned by read_sha1_file.

ca51699 tag: fix output of "tag -n" when errors occur When "git tag" is instructed to print lines from annotated tags via "-n", it first prints the tag name, then attempts to parse and print the lines of the tag object, and then finally adds a trailing newline. If an error occurs, we return early from the function and never print the newline, screwing up the output for the next tag. Let's factor the line-printing into its own function so we can manage the early returns better, and make sure that we always terminate the line.

c2d17ba branch --edit-description: protect against mistyped branch name It is very easy to mistype the branch name when editing its description, e.g. $ git checkout -b my-topic master : work work work : now we are at a good point to switch working something else $ git checkout master : ah, let's write it down before we forget what we were doing $ git branch --edit-description my-tpoic The command does not notice that branch 'my-tpoic' does not exist. It is not lost (it becomes description of an unborn my-tpoic branch), but is not very useful. So detect such a case and error out to reduce the grief factor from this common mistake. This incidentally also errors out --edit-description when the HEAD points at an unborn branch (immediately after "init", or "checkout --orphan"), because at that point, you do not even have any commit that is part of your history and there is no point in describing how this particular branch is different from the branch it forked off of, which is the useful bit of information the branch description is designed to capture. We may want to special case the unborn case later, but that is outside the scope of this patch to prevent more common mistakes before 1.7.9 series gains too much widespread use.

b5c9f1c merge: do not create a signed tag merge under --ff-only option Starting at release v1.7.9, if you ask to merge a signed tag, "git merge" always creates a merge commit, even when the tag points at a commit that happens to be a descendant of your current commit. Unfortunately, this interacts rather badly for people who use --ff-only to make sure that their branch is free of local developments. It used to be possible to say: $ git checkout -b frotz v1.7.9~30 $ git merge --ff-only v1.7.9 and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka the commit tagged as v1.7.9), but this fails with the updated Git with: fatal: Not possible to fast-forward, aborting. because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by fast forwarding. We could teach users that now they have to do $ git merge --ff-only v1.7.9^0 but it is far more pleasant for users if we DWIMmed this ourselves. When an integrator pulls in a topic from a lieutenant via a signed tag, even when the work done by the lieutenant happens to fast-forward, the integrator wants to have a merge record, so the integrator will not be asking for --ff-only when running "git pull" in such a case. Therefore, this change should not regress the support for the use case v1.7.9 wanted to add. Signed-off-by: Junio C Hamano <gitster@pobox.com> 06 February 2012, 00:30:26 UTC
2c733fb parse_date(): '@' prefix forces git-timestamp The only place that the issue this series addresses was observed where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE in order to replay a commit with an ancient timestamp. With the previous patch alone, "git commit --date='20100917 +0900'" can be misinterpreted to mean an ancient timestamp, not September in year 2010. Guard this codepath by requring an extra '@' in front of the raw git timestamp on the parsing side. This of course needs to be compensated by updating get_author_ident_from_commit and the code for "git commit --amend" to prepend '@' to the string read from the existing commit in the GIT_AUTHOR_DATE environment variable.

116eb3a parse_date(): allow ancient git-timestamp The date-time parser parses out a human-readble datestring piece by piece, so that it could even parse a string in a rather strange notation like 'noon november 11, 2005', but restricts itself from parsing strings in "<seconds since epoch> <timezone>" format only for reasonably new timestamps (like 1974 or newer) with 10 or more digits. This is to prevent a string like "20100917" from getting interpreted as seconds since epoch (we want to treat it as September 17, 2010 instead) while doing so. The same codepath is used to read back the timestamp that we have already recorded in the headers of commit and tag objects; because of this, such a commit with timestamp "0 +0000" cannot be rebased or amended very easily. Teach parse_date() codepath to special case a string of the form "<digits> +<4-digits>" to work this issue around, but require that there is no other cruft around the string when parsing a timestamp of this format for safety. Note that this has a slight backward incompatibility implications. If somebody writes "git commit --date='20100917 +0900'" and wants it to mean a timestamp in September 2010 in Japan, this change will break such a use case.

840c519 tests: add write_script helper function Many of the scripts in the test suite write small helper shell scripts to disk. It's best if these shell scripts start with "#!$SHELL_PATH" rather than "#!/bin/sh", because /bin/sh on some platforms is too buggy to be used. However, it can be cumbersome to expand $SHELL_PATH, because the usual recipe for writing a script is: cat >foo.sh <<-\EOF #!/bin/sh echo my arguments are "$@" EOF To expand $SHELL_PATH, you have to either interpolate the here-doc (which would require quoting "\$@"), or split the creation into two commands (interpolating the $SHELL_PATH line, but not the rest of the script). Let's provide a helper function that makes that less syntactically painful. While we're at it, this helper can also take care of the "chmod +x" that typically comes after the creation of such a script, saving the caller a line.

2ad9ba0 request-pull: explicitly ask tags/$name to be pulled When asking for a tag to be pulled, disambiguate by leaving tags/ prefix in front of the name of the tag. E.g. ... in the git repository at: git://example.com/git/git.git/ tags/v1.2.3 for you to fetch changes up to 123456... This way, older versions of "git pull" can be used to respond to such a request more easily, as "git pull $URL v1.2.3" did not DWIM to fetch v1.2.3 tag in older versions. Also this makes it clearer for humans that the pull request is made for a tag and he should anticipate a signed one. Signed-off-by: Junio C Hamano <gitster@pobox.com> 01 February 2012, 05:27:58 UTC

f15026b git-completion: workaround zsh COMPREPLY bug zsh adds a backslash (foo\ ) for each item in the COMPREPLY array if IFS doesn't contain spaces. This issue has been reported[1], but there is no solution yet. This wasn't a problem due to another bug[2], which was fixed in zsh version 4.3.12. After this change, 'git checkout ma<tab>' would resolve to 'git checkout master\ '. Aditionally, the introduction of __gitcomp_nl in commit a31e626 (completion: optimize refs completion) in git also made the problem apparent, as Matthieu Moy reported. The simplest and most generic solution is to hide all the changes we do to IFS, so that "foo \nbar " is recognized by zsh as "foo bar". This works on versions of git before and after the introduction of __gitcomp_nl (a31e626), and versions of zsh before and after 4.3.12. Once zsh is fixed, we should conditionally disable this workaround to have the same benefits as bash users.

1017c1a submodule add: fix breakage when re-adding a deep submodule Since recently a submodule with name <name> has its git directory in the .git/modules/<name> directory of the superproject while the work tree contains a gitfile pointing there. When the same submodule is added on a branch where it wasn't present so far (it is not found in the .gitmodules file), the name is not initialized from the path as it should. This leads to a wrong path entered in the gitfile when the .git/modules/<name> directory is found, as this happily uses the - now empty - name. It then always points only a single directory up, even if we have a path deeper in the directory hierarchy. Fix that by initializing the name of the submodule early in module_clone() if module_name() returned an empty name and add a test to catch that bug.

5238cbf remote-curl: Fix push status report when all branches fail The protocol between transport-helper.c and remote-curl requires remote-curl to always print a blank line after the push command has run. If the blank line is ommitted, transport-helper kills its container process (the git push the user started) with exit(128) and no message indicating a problem, assuming the helper already printed reasonable error text to the console. However if the remote rejects all branches with "ng" commands in the report-status reply, send-pack terminates with non-zero status, and in turn remote-curl exited with non-zero status before outputting the blank line after the helper status printed by send-pack. No error messages reach the user. This caused users to see the following from git push over HTTP when the remote side's update hook rejected the branch: $ git push http://... master Counting objects: 4, done. Delta compression using up to 6 threads. Compressing objects: 100% (2/2), done. Writing objects: 100% (3/3), 301 bytes, done. Total 3 (delta 0), reused 0 (delta 0) $ Always print a blank line after the send-pack process terminates, ensuring the helper status report (if it was output) will be correctly parsed by the calling transport-helper.c. This ensures the helper doesn't abort before the status report can be shown to the user. Signed-off-by: Shawn O.

36ed191 Making pathspec limited log play nicer with --first-parent In a topic branch workflow, you often want to find the latest commit that merged a side branch that touched a particular area of the system, so that a new topic branch to work on that area can be forked from that commit. For example, I wanted to find an appropriate fork-point to queue Luke's changes related to git-p4 in contrib/fast-import/. "git log --first-parent" traverses the first-parent chain, and "-m --stat" shows the list of paths touched by commits including merge commits. We could ask the question this way: # What is the latest commit that touched that path? $ git log --first-parent --oneline -m --stat master | sed -e '/^ contrib\/fast-import\/git-p4 /q' | tail The above finds that 8cbfc11 (Merge branch 'pw/p4-view-updates', 2012-01-06) was such a commit. But a more natural way to spell this question is this: $ git log --first-parent --oneline -m --stat -1 master -- \ contrib/fast-import/git-p4 Unfortunately, this does not work. It finds ecb7cf9 (git-p4: rewrite view handling, 2012-01-02). This commit is a part of the merged topic branch and is _not_ on the first-parent path from the 'master': $ git show-branch 8cbfc11 ecb7cf9 ! [8cbfc11] Merge branch 'pw/p4-view-updates' ! [ecb7cf9] git-p4: rewrite view handling -- - [8cbfc11] Merge branch 'pw/p4-view-updates' + [8cbfc11^2] git-p4: view spec documentation ++ [ecb7cf9] git-p4: rewrite view handling The problem is caused by the merge simplification logic when it inspects the merge commit 8cbfc11. In this case, the history leading to the tip of 'master' did not touch git-p4 since 'pw/p4-view-updates' topic forked, and the result of the merge is simply a copy from the tip of the topic branch in the view limited by the given pathspec. The merge simplification logic discards the history on the mainline side of the merge, and pretends as if the sole parent of the merge is its second parent, i.e. the tip of the topic. While this simplification is correct in the general case, it is at least surprising if not outright wrong when the user explicitly asked to show the first-parent history. Here is an attempt to fix this issue, by not allowing us to compare the merge result with anything but the first parent when --first-parent is in effect, to avoid the history traversal veering off to the side branch.

5c8eeb8 diff-index: enable recursive pathspec matching in unpack_trees The pathspec structure has a few bits of data to drive various operation modes after we unified the pathspec matching logic in various codepaths. For example, max_depth field is there so that "git grep" can limit the output for files found in limited depth of tree traversal. Also in order to show just the surface level differences in "git diff-tree", recursive field stops us from descending into deeper level of the tree structure when it is set to false, and this also affects pathspec matching when we have wildcards in the pathspec. The diff-index has always wanted the recursive behaviour, and wanted to match pathspecs without any depth limit. But we forgot to do so when we updated tree_entry_interesting() logic to unify the pathspec matching logic.

35a71f1 credential-cache: ignore "connection refused" errors The credential-cache helper will try to connect to its daemon over a unix socket. Originally, a failure to do so was silently ignored, and we would either give up (if performing a "get" or "erase" operation), or spawn a new daemon (for a "store" operation). But since 8ec6c8d, we try to report more errors. We detect a missing daemon by checking for ENOENT on our connection attempt. If the daemon is missing, we continue as before (giving up or spawning a new daemon). For any other error, we die and report the problem. However, checking for ENOENT is not sufficient for a missing daemon. We might also get ECONNREFUSED if a dead daemon process left a stale socket. This generally shouldn't happen, as the daemon cleans up after itself, but the daemon may not always be given a chance to do so (e.g., power loss, "kill -9"). The resulting state is annoying not just because the helper outputs an extra useless message, but because it actually blocks the helper from spawning a new daemon to replace the stale socket. Fix it by checking for ECONNREFUSED. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com> 17 January 2012, 06:15:19 UTC

6ab2608 git-show-ref: fix escaping in asciidoc source Two "^" characters were incorrectly being interpreted as markup for superscripting. Fix them by writing them as attribute references "{caret}". Although a single "^" character in a paragraph cannot be misinterpreted in this way, also write other "^" characters as "{caret}" in the interest of good hygiene (unless they are in literal paragraphs, of course, in which context attribute references are not recognized). Spell "{}" consistently, namely *not* quoted as "\{\}". Since the braces are empty, they cannot be interpreted as an attribute reference, and either spelling is OK.

15f07e0 thin-pack: try harder to use preferred base objects as base When creating a pack using objects that reside in existing packs, we try to avoid recomputing futile delta between an object (trg) and a candidate for its base object (src) if they are stored in the same packfile, and trg is not recorded as a delta already. This heuristics makes sense because it is likely that we tried to express trg as a delta based on src but it did not produce a good delta when we created the existing pack. As the pack heuristics prefer producing delta to remove data, and Linus's law dictates that the size of a file grows over time, we tend to record the newest version of the file as inflated, and older ones as delta against it. When creating a thin-pack to transfer recent history, it is likely that we will try to send an object that is recorded in full, as it is newer. But the heuristics to avoid recomputing futile delta effectively forbids us from attempting to express such an object as a delta based on another object. Sending an object in full is often more expensive than sending a suboptimal delta based on other objects, and it is even more so if we could use an object we know the receiving end already has (i.e. preferred base object) as the delta base. Tweak the recomputation avoidance logic, so that we do not punt on computing delta against a preferred base object. The effect of this change can be seen on two simulated upload-pack workloads. The first is based on 44 reflog entries from my git.git origin/master reflog, and represents the packs that kernel.org sent me git updates for the past month or two. The second workload represents much larger fetches, going from git's v1.0.0 tag to v1.1.0, then v1.1.0 to v1.2.0, and so on. The table below shows the average generated pack size and the average CPU time consumed for each dataset, both before and after the patch: dataset | reflog | tags --------------------------------- before | 53358 | 2750977 size after | 32398 | 2668479 change | -39% | -3% --------------------------------- before | 0.18 | 1.12 CPU after | 0.18 | 1.15 change | +0% | +3% This patch makes a much bigger difference for packs with a shorter slice of history (since its effect is seen at the boundaries of the pack) though it has some benefit even for larger packs.

c7c2bc0 word-diff: ignore '\ No newline at eof' marker The word-diff logic accumulates + and - lines until another line type appears (normally [ @\]), at which point it generates the word diff. This is usually correct, but it breaks when the preimage does not have a newline at EOF: $ printf "%s" "a a a" >a $ printf "%s\n" "a ab a" >b $ git diff --no-index --word-diff a b diff --git 1/a 2/b index 9f68e94..6a7c02f 100644 --- 1/a +++ 2/b @@ -1 +1 @@ [-a a a-] No newline at end of file {+a ab a+} Because of the order of the lines in a unified diff @@ -1 +1 @@ -a a a \ No newline at end of file +a ab a the '\' line flushed the buffers, and the - and + lines were never matched with each other. A proper fix would defer such markers until the end of the hunk. However, word-diff is inherently whitespace-ignoring, so as a cheap fix simply ignore the marker (and hide it from the output). We use a prefix match for '\ ' to parallel the logic in apply.c:parse_fragment(). We currently do not localize this string (just accept other variants of it in git-apply), but this should be future-proof.

06121a0 unix-socket: do not let close() or chdir() clobber errno during cleanup unix_stream_connect and unix_stream_listen return -1 on error, with errno set by the failing underlying call to allow the caller to write a useful diagnosis. Unfortunately the error path involves a few system calls itself, such as close(), that can themselves touch errno. This is not as worrisome as it might sound. If close() fails, this just means substituting one meaningful error message for another, which is perfectly fine. However, when the call _succeeds_, it is allowed to (and sometimes might) clobber errno along the way with some undefined value, so it is good higiene to save errno and restore it immediately before returning to the caller.
