| * sh-setup: work around "unset IFS" bug in some shellsJunio C Hamano2012-12-101-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With an unset IFS, field splitting is supposed to act as if IFS is set to the usual SP HT LF, but Marc Branchaud reports that the shell on FreeBSD 7.2 gets this wrong. It is easy to set it to the default value manually, and it is also safer in case somebody tries to save the old value away and restore, e.g. $oIFS=$IFS IFS=something ... IFS=$oIFS while forgetting that the original IFS might be unset (which can be coded but would be more involved). Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | git-sh-setup: refactor ident-parsing functionsJeff King2012-10-181-19/+43
|/ | | | | | | | | | | | | | | | | | | The only ident-parsing function we currently provide is get_author_ident_from_commit. This is not very flexible for two reasons: 1. It takes a commit as an argument, and can't read from commit headers saved on disk. 2. It will only parse authors, not committers. This patch provides a more flexible interface which will parse multiple idents from a commit provide on stdin. We can easily use it as a building block for the current function to retain compatibility. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

|\ | | | | | | | | | | | | | | | | When the user exports a non-default IFS without HT, scripts that rely on being able to parse "ls-files -s | while read a b c..." start to fail. Protect them from such a misconfiguration. * jc/maint-protect-sh-from-ifs: sh-setup: protect from exported IFS

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many scripted Porcelains rely on being able to split words at the default $IFS characters, i.e. SP, HT and LF. If the user exports a non-default IFS to the environment, what they read from plumbing commands such as ls-files that use HT to delimit fields may not be split in the way we expect. Protect outselves by resetting it, just like we do so against CDPATH exported to the environment. Noticed by Andrew Dranse <adranse@oanda.com>. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* require-work-tree wants more than what its name saysJunio C Hamano2011-05-241-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Somebody tried "git pull" from a random place completely outside the work tree, while exporting GIT_DIR and GIT_WORK_TREE that are set to correct places, e.g. GIT_WORK_TREE=$HOME/git.git GIT_DIR=$GIT_WORK_TREE/.git export GIT_WORK_TREE GIT_DIR cd /tmp git pull At the beginning of git-pull, we check "require-work-tree" and then "cd-to-toplevel". I _think_ the original intention when I wrote the command was "we MUST have a work tree, our $(cwd) might not be at the top-level directory of it", and no stronger than that. That check is a very sensible thing to do before doing cd-to-toplevel. We check that the place we would want to go exists, and then go there. But the implementation of require_work_tree we have today is quite different. I don't have energy to dig the history, but currently it says: test "$(git rev-parse --is-inside-work-tree 2>/dev/null)" = true || die "fatal: $0 cannot be used without a working tree." Which is completely bogus. Even though we may happen to be just outside of it right now, we may have a working tree that we can cd_to_toplevel back to. Add a function "require_work_tree_exists" that implements the check this function originally intended (this is so that third-party scripts that rely on the current behaviour do not have to get broken). For now, update _no_ in-tree scripts, not even "git pull", as nobody on the list seems to really care about the above corner case workflow that triggered this. Scripts can be updated after vetting that they do want the "we want to make sure the place we are going to go actually exists" semantics. Signed-off-by: Junio C Hamano <gitster@pobox.com>

For example, we may want to count number of matching lines, by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use. The approach taken by this change to address this issue is to protect only our own use of grep/egrep. Because we do not unset it at the beginning of our scripts, hook scripts run from the scripted Porcelains are exposed to the same insanity this environment variable causes when grep/egrep is used to implement logic (e.g. "grep | wc -l"), and it is entirely up to the hook scripts to protect themselves. On the other hand, applypatch-msg hook may want to show offending words in the proposed commit log message using grep to the end user, and the user might want to set GREP_OPTIONS=--color to paint the match more visibly. The approach to protect only our own use without unsetting the environment variable globally will allow this use case. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | Makefile: insert SANE_TOOL_PATH to PATH before /bin or /usr/binJunio C Hamano2009-06-101-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an earlier patch, we introduced SANE_TOOL_PATH that is prepended to user's PATH. This had an unintended consequence of overriding user's private binary directory that typically comes earlier in the PATH to holds even saner commands than whatever comes with the system. For example, a user may have ~/bin that is early in the path and contains a shell script "vi" that launches system's /bin/vi with specific options. Prepending SANE_TOOL_PATH to the PATH that happens to have "vi" in it defeats such customization. This fixes the issue by inserting SANE_TOOL_PATH just before /bin or /usr/bin appears on the PATH.

Some of the features provided by these modern binaries are expected and required by git. If the featureful binaries are not in the users path, then git could end up using the less featureful binary and fail. So provide a mechanism to prepend elements to the users PATH at runtime so the modern binaries will be found.

The "-P" option yields a desirable similarity to C chdir. While the "-P" option may be slightly less commonly supported than /bin/pwd, it is more concise, better tested, and less error prone. I've already added the 'unset PWD' to fix the /bin/pwd solution on BSD; there may be more edge cases out there. This still passes all the same test cases in t5521-pull-symlink.sh and t2300-cd-to-toplevel.sh, even before updating them to use 'pwd -P'. Signed-off-by: Junio C Hamano <gitster@pobox.com>

A build system's install step could solve this, but I develop scripts and web pages that don't need to be built. Git's submodule system could solve this, but we tend to develop, branch, and test those directories all in unison, so one big repository feels more natural. We prefer to edit and commit on the symlinked paths, not the canonical ones, and in that setting, "git pull" fails to find the top-level directory of the repository while other commands work fine. "git pull" fails because POSIX shells have a notion of current working directory that is different from getcwd(). The shell stores this path in PWD. As a result, "cd ../" can be interpreted differently in a shell script than chdir("../") in a C program. The shell interprets "../" by essentially stripping the last textual path component from PWD, whereas C chdir() follows the ".." link in the current directory on the filesystem. When PWD is a symlink, these are different destinations. As a result, Git's C commands find the correct top-level working tree, and shell scripts do not. Changes: * When interpreting a relative upward (../) path in cd_to_toplevel, prepend the cwd without symlinks, given by /bin/pwd * Add tests for cd_to_toplevel and "git pull" in a symlinked directory that failed before this fix, plus contrasting scenarios that already worked Signed-off-by: Marcel M.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you set OPTIONS_SPEC, git-sh-setups uses git-rev-parse --parseopt automatically. It also diverts usage to re-exec $0 with the -h option as parse-options.c will catch that. If you need git-rev-parse --parseopt to keep the `--` the user may have passed to your command, set OPTIONS_KEEPDASHDASH to a non empty value in your script.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Quite a few of the scripts are rather careless about using GIT_DIR while changing directories. Some try their hands (with different likelihood of success) in making GIT_DIR absolute. This patch lets git-sh-setup.sh cater for absolute directories (in a way that should work reliably also with non-Unix path names) and removes the respective kludges in git-filter-branch.sh and git-instaweb.sh.

* | git-sh-setup.sh: make GIT_EDITOR/core.editor/VISUAL/EDITOR accept commandsDavid Kastrup2007-08-011-2/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code only allowed specifying a single executable rather than a complete command like "emacsclient --alternate-editor vi" in those variables. Since VISUAL/EDITOR appear to be traditionally passed to a shell for interpretation (as corroborated with "less", "mail" and "mailx", while the really ancient "more" indeed allows only an executable name), the shell function git_editor has been amended appropriately. "eval" is employed to have quotes and similar interpreted _after_ expansion, so that specifying EDITOR='"/home/dak/My Commands/notepad.exe"' can be used for actually using commands with blanks. Instead of passing just the first argument of git_editor on, we pass all of them (so that +lineno might be employed at a later point of time, or so that multiple files may be edited when appropriate). Strictly speaking, there is a change in behavior: when git config core.editor returns a valid but empty string, the fallbacks are still searched. This is more consistent, and the old code was problematic with regard to multiple blanks. Putting in additional quotes might have worked, but quotes inside of command substitution inside of quotes is nasty enough to not reliably work the same across "Bourne shells".

* Clean up work-tree handlingJohannes Schindelin2007-08-011-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old version of work-tree support was an unholy mess, barely readable, and not to the point. For example, why do you have to provide a worktree, when it is not used? As in "git status". Now it works. Another riddle was: if you can have work trees inside the git dir, why are some programs complaining that they need a work tree? IOW it is allowed to call $ git --git-dir=../ --work-tree=. bla when you really want to. In this case, you are both in the git directory and in the working tree. So, programs have to actually test for the right thing, namely if they are inside a working tree, and not if they are inside a git directory. Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was specified, unless there is a repository in the current working directory. It does now. The logic to determine if a repository is bare, or has a work tree (tertium non datur), is this: --work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true, which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR ends in /.git, which overrides the directory in which .git/ was found. In related news, a long standing bug was fixed: when in .git/bla/x.git/, which is a bare repository, git formerly assumed ../.. to be the appropriate git dir. This problem was reported by Shawn Pearce to have caused much pain, where a colleague mistakenly ran "git init" in "/" a long time ago, and bare repositories just would not work.
