Handle symlinks graciously This patch converts a stat() to an lstat() call, thereby fixing the case when the date of a symlink was not the same as the one recorded in the index. The included test case demonstrates this. This is for the case that the symlink points to a non-existing file. If the file exists, worse things than just an error message happen.

tests: use $TEST_DIRECTORY to refer to the t/ directory Many test scripts assumed that they will start in a 'trash' subdirectory that is a single level down from the t/ directory, and referred to their test vector files by asking for files like "../t9999/expect". This will break if we move the 'trash' subdirectory elsewhere. To solve this, we earlier introduced "$TEST_DIRECTORY" so that they can refer to t/ directory reliably. This finally makes all the tests use it to refer to the outside environment.

diff -p: squelch "diff --git" header for stat-dirty paths The plumbing "diff" commands look at the working tree files without refreshing the index themselves for performance reasons (the calling script is expected to do that upfront just once, before calling one or more of them). In the early days of git, they showed the "diff --git" header before they actually ask the xdiff machinery to produce patches, and ended up showing only these headers if the real contents are the same and the difference they noticed was only because the stat info cached in the index did not match that of the working tree. It was too late for the implementation to take the header that it already emitted back. But 3e97c7c (No diff -b/-w output for all-whitespace changes, 2009-11-19) introduced necessary logic to keep the meta-information headers in a strbuf and delay their output until the xdiff machinery noticed actual changes. This was primarily in order to generate patches that ignore whitespaces. When operating under "-w" mode, we wouldn't know if the header is needed until we actually look at the resulting patch, so it was a sensible thing to do, but we did not realize that the same reasoning applies to stat-dirty paths. Later, 296c6bb (diff: fix "git show -C -C" output when renaming a binary file, 2010-05-26) generalized this machinery and added must_show_header toggle. This is turned on when the header must be shown even when there is no patch to be produced, e.g. only the mode was changed, or the path was renamed, without changing the contents. However, when it did so, it still kept the special case for the "-w" mode, which meant that the plumbing would keep showing these phantom changes. This corrects this historical inconsistency by allowing the plumbing to omit paths that are only stat-dirty from its output in the same way as it handles whitespace only changes under "-w" option. The change in the behaviour can be seen in the updated test. Signed-off-by: Junio C Hamano <gitster@pobox.com>

t4011: illustrate "diff-index -p" on stat-dirty paths The plumbing that looks at the working tree, i.e. "diff-index" and "diff-files", always emit the "diff --git a/path b/path" header lines without anything else for paths that are only stat-dirty (i.e. different only because the cached stat information in the index no longer matches that of the working tree, but the real contents are the same), when these commands are run with "-p" option to produce patches. Illustrate this current behaviour. Also demonstrate that with the "-w" option, we (correctly) hold off showing a "diff --git" header until actual differences have been found. This also suppresses the header for merely stat-dirty files, which is inconsistent. Signed-off-by: Junio C Hamano <gitster@pobox.com>

t4011: remove SYMLINKS prerequisite The part of the test that is about symbolic links in the index does not require that the corresponding file system entry is actually a symbolic link. Use test_ln_s_add to insert a symbolic link in the index. When the file system does not support symbolic links, we actually have a regular file in the worktree, which we can update as if it were a symbolic link. diff-index picks up the symbolic link property from the index.

Handle symlinks graciously This patch converts a stat() to an lstat() call, thereby fixing the case when the date of a symlink was not the same as the one recorded in the index. The included test case demonstrates this. This is for the case that the symlink points to a non-existing file. If the file exists, worse things than just an error message happen.

diff: don't use pathname-based diff drivers for symlinks When we're diffing symlinks, we consider the contents to be the pathname that the symlink points to. When a user sets up a userdiff driver like "*.pdf diff=pdf", their "diff.pdf.*" config generally tells us what to do with the content of pdf files. With the current code, we will actually process a symlink like "link.pdf" using a configured pdf driver, meaning we are using contents which consist of a pathname with configuration that is expecting contents that consist of an actual pdf file. The most noticeable example of this would have been textconv; however, it was already protected in its own textconv-specific code path. We can still see the breakage with something like "diff.*.binary", though. You could also see it with diff.*.funcname, though it is a bit harder to trigger accidentally there. This patch adds a check for S_ISREG lower in the callstack than the textconv-specific check, which should block use of any userdiff config for non-regular files. We can drop the check in the textconv code, which is now redundant. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
