From f245194f9a13d5108c3a59fd4ab1770ae9fd5b65 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 22 May 2009 12:45:29 -0700 Subject: diff: change semantics of "ignore whitespace" options Traditionally, the --ignore-whitespace* options have merely meant to tell the diff output routine that some class of differences are not worth showing in the textual diff output, so that the end user has easier time to review the remaining (presumably more meaningful) changes. These options never affected the outcome of the command, given as the exit status when the --exit-code option was in effect (either directly or indirectly). When you have only whitespace changes, however, you might expect git diff -b --exit-code to report that there is _no_ change with zero exit status. Change the semantics of --ignore-whitespace* options to mean more than "omit showing the difference in text". The exit status, when --exit-code is in effect, is computed by checking if we found any differences at the path level, while diff frontends feed filepairs to the diffcore engine. When "ignore whitespace" options are in effect, we defer this determination until the very end of diffcore transformation. We simply do not know until the textual diff is generated, which comes very late in the pipeline. When --quiet is in effect, various diff frontends optimize by breaking out early from the loop that enumerates the filepairs, when we find the first path level difference; when --ignore-whitespace* is used the above change automatically disables this optimization.

As a side effect, because there is no point showing one change that we happened to have found first, it also enables NO_OUTPUT and EXIT_WITH_STATUS options, making the end result look quiet. Rename the internal option to QUICK to reflect this better; it also makes grepping the source tree much easier, as there are other kinds of QUIET option everywhere.

Running through the shell is useful because the user can provide a program with command line arguments, like "antiword -f". It also makes textconv more consistent with other parts of git, most of which run their helpers using the shell. The downside is that textconv helpers with shell metacharacters (like space) in the filename will be broken.

When unpack_callback() is fed a set of tree entries from trees, it inspects the name of the entry and checks if the an index entry with the same name could be hiding behind the current index entry, and (1) if the name appears in the index as a leaf node, it is also fed to the n_way_merge() callback function; (2) if the name is a directory in the index, i.e. there are entries in that are underneath it, then nothing is fed to the n_way_merge() callback function; (3) otherwise, if the name comes before the first eligible entry in the index, the index entry is first unpacked alone. When traverse_trees_recursive() descends into a subdirectory, the cache_bottom pointer is moved to walk index entries within that directory. All of these are omitted for diff-index, which does not even want to be fed an index entry and a tree entry with D/F conflicts.

"master" created "a/b" symlink that did not exist, and removed "a/b/c/d" while HEAD did not do touch either path. Before this series, read-tree did not notice the situation and resolved addition of "a/b" and removal of "a/b/c/d" independently. If A = HEAD had another path "a/b/c/e" added, this merge should conflict but instead it silently resolved "a/b" and then immediately overwrote it to add "a/b/c/e", which was quite bogus.

The information we got from scanning the whole submodule tree the first time can be reused instead. New parameters have been added to diff_change() and diff_addremove(), the information is stored in a new member of struct diff_filespec. Its value is then reused instead of calling is_submodule_modified() again. When no explicit "-dirty" is needed in the output the call to is_submodule_modified() is not necessary when the submodules HEAD already disagrees with the ref of the superproject, as this alone marks it as modified. To achieve that, get_stat_data() got an extra argument.
