builtin-commit: fix partial-commit support When making a partial-commit, we need to prepare two index files, one to be used to write out the tree to be committed (temporary index) and the other to be used as the index file after the commit is made. The temporary index needs to be initialized to HEAD and then all the named paths on the command line need to be staged on top of the index. For this, running add_files_to_cache() that compares what is in the index and the paths given from the command line is not enough -- the comparison will miss the paths that the user previously ran "git add" to the index since the HEAD because the index reset to the HEAD would not know about them. The index file needs to get the same modification done when preparing the temporary index as described above. This implementation mimics the behaviour of the scripted version of git-commit. It first runs overlay_tree_on_cache(), which was stolen from ls-files with the earlier change, to get the list of paths that the user can potentially mean, and then uses pathspec_match() to find which ones the user meant. This list of paths is used to update both the temporary and the real index file. Additional fixes are: - read the index file after pre-commit hook returns, as the hook can modify it to affect the contents of the commit. - remove the temporary index file .git/next-index-* after commit is done or aborted. - run post-commit hook with the real index file to be used after the commit (previously it gave the temporary commit if a partial commit was made). - resurrect the safety mechanism to refuse partial commits during a merge to match the scripted version.

commit: teach --gpg-sign option This uses the gpg-interface.[ch] to allow signing the commit, i.e. $ git commit --gpg-sign -m foo You need a passphrase to unlock the secret key for user: "Junio C Hamano <gitster@pobox.com>" 4096-bit RSA key, ID 96AFE6CB, created 2011-10-03 (main key ID 713660A7) [master 8457d13] foo 1 files changed, 1 insertions(+), 0 deletions(-) The lines of GPG detached signature are placed in a new multi-line header field, instead of tucking the signature block at the end of the commit log message text (similar to how signed tag is done), for multiple reasons: - The signature won't clutter output from "git log" and friends if it is in the extra header. If we place it at the end of the log message, we would need to teach "git log" and friends to strip the signature block with an option. - Teaching new versions of "git log" and "gitk" to optionally verify and show signatures is cleaner if we structurally know where the signature block is (instead of scanning in the commit log message). - The signature needs to be stripped upon various commit rewriting operations, e.g. rebase, filter-branch, etc. They all already ignore unknown headers, but if we place signature in the log message, all of these tools (and third-party tools) also need to learn how a signature block would look like. - When we added the optional encoding header, all the tools (both in tree and third-party) that acts on the raw commit object should have been fixed to ignore headers they do not understand, so it is not like that new header would be more likely to break than extra text in the commit. A commit made with the above sample sequence would look like this: $ git cat-file commit HEAD tree 3cd71d90e3db4136e5260ab54599791c4f883b9d parent b87755351a47b09cb27d6913e6e0e17e6254a4d4 author Junio C Hamano <gitster@pobox.com> 1317862251 -0700 committer Junio C Hamano <gitster@pobox.com> 1317862251 -0700 gpgsig -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJOjPtrAAoJELC16IaWr+bL4TMP/RSe2Y/jYnCkds9unO5JEnfG ... =dt98 -----END PGP SIGNATURE----- foo but "git log" (unless you ask for it with --pretty=raw) output is not cluttered with the signature information.

commit: show interesting ident information in summary There are a few cases of user identity information that we consider interesting: (1) When the author and committer identities do not match.

Add the option "--ignore-submodules" to "git status" In some use cases it is not desirable that "git status" considers submodules that only contain untracked content as dirty. This may happen e.g. when the submodule is not under the developers control and not all build generated files have been added to .gitignore by the upstream developers. Using the "untracked" parameter for the "--ignore-submodules" option disables checking for untracked content and lets git diff report them as changed only when they have new commits or modified content. Sometimes it is not wanted to have submodules show up as changed when they just contain changes to their work tree (this was the behavior before 1.7.0). An example for that are scripts which just want to check for submodule commits while ignoring any changes to the work tree. Also users having large submodules known not to change might want to use this option, as the - sometimes substantial - time it takes to scan the submodule work tree(s) is saved when using the "dirty" parameter. And if you want to ignore any changes to submodules, you can now do that by using this option without parameters or with "all" (when the config option status.submodulesummary is set, using "all" will also suppress the output of the submodule summary). A new function handle_ignore_submodules_arg() is introduced to parse this option new to "git status" in a single location, as "git diff" already knew it.

Convert "struct cache_entry *" to "const ..." wherever possible I attempted to make index_state->cache[] a "const struct cache_entry **" to find out how existing entries in index are modified and where. The question I have is what do we do if we really need to keep track of on-disk changes in the index. The result is - diff-lib.c: setting CE_UPTODATE - name-hash.c: setting CE_HASHED - preload-index.c, read-cache.c, unpack-trees.c and builtin/update-index: obvious - entry.c: write_entry() may refresh the checked out entry via fill_stat_cache_info(). This causes "non-const struct cache_entry *" in builtin/apply.c, builtin/checkout-index.c and builtin/checkout.c - builtin/ls-files.c: --with-tree changes stagemask and may set CE_UPDATE Of these, write_entry() and its call sites are probably most interesting because it modifies on-disk info. But this is stat info and can be retrieved via refresh, at least for porcelain commands. Other just uses ce_flags for local purposes. So, keeping track of "dirty" entries is just a matter of setting a flag in index modification functions exposed by read-cache.c. Except unpack-trees, the rest of the code base does not do anything funny behind read-cache's back. The actual patch is less valueable than the summary above. But if anyone wants to re-identify the above sites. Applying this patch, then this: diff --git a/cache.h b/cache.h index 430d021..1692891 100644 --- a/cache.h +++ b/cache.h @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode) #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1) struct index_state { - struct cache_entry **cache; + const struct cache_entry **cache; unsigned int version; unsigned int cache_nr, cache_alloc, cache_changed; struct string_list *resolve_undo; will help quickly identify them without bogus warnings.

builtin-commit: fix partial-commit support When making a partial-commit, we need to prepare two index files, one to be used to write out the tree to be committed (temporary index) and the other to be used as the index file after the commit is made. The temporary index needs to be initialized to HEAD and then all the named paths on the command line need to be staged on top of the index. For this, running add_files_to_cache() that compares what is in the index and the paths given from the command line is not enough -- the comparison will miss the paths that the user previously ran "git add" to the index since the HEAD because the index reset to the HEAD would not know about them. The index file needs to get the same modification done when preparing the temporary index as described above. This implementation mimics the behaviour of the scripted version of git-commit. It first runs overlay_tree_on_cache(), which was stolen from ls-files with the earlier change, to get the list of paths that the user can potentially mean, and then uses pathspec_match() to find which ones the user meant. This list of paths is used to update both the temporary and the real index file. Additional fixes are: - read the index file after pre-commit hook returns, as the hook can modify it to affect the contents of the commit. - remove the temporary index file .git/next-index-* after commit is done or aborted. - run post-commit hook with the real index file to be used after the commit (previously it gave the temporary commit if a partial commit was made). - resurrect the safety mechanism to refuse partial commits during a merge to match the scripted version.

Be more user-friendly when refusing to do something because of conflict. Various commands refuse to run in the presence of conflicts (commit, merge, pull, cherry-pick/revert). They all used to provide rough, and inconsistant error messages. A new variable advice.resolveconflict is introduced, and allows more verbose messages, pointing the user to the appropriate solution. For commit, the error message used to look like this: $ git commit foo.txt: needs merge foo.txt: unmerged (c34a92682e0394bc0d6f4d4a67a8e2d32395c169) foo.txt: unmerged (3afcd75de8de0bb5076942fcb17446be50451030) foo.txt: unmerged (c9785d77b76dfe4fb038bf927ee518f6ae45ede4) error: Error building trees The "need merge" line is given by refresh_cache. We add the IN_PORCELAIN option to make the output more consistant with the other porcelain commands, and catch the error in return, to stop with a clean error message. The next lines were displayed by a call to cache_tree_update(), which is not reached anymore if we noticed the conflict. The new output looks like: U foo.txt fatal: 'commit' is not possible because you have unmerged files. Please, fix them up in the work tree, and then use 'git add/rm <file>' as appropriate to mark resolution and make a commit, or use 'git commit -a'. Pull is slightly modified to abort immediately if $GIT_DIR/MERGE_HEAD exists instead of waiting for merge to complain. The behavior of merge and the test-case are slightly modified to reflect the usual flow: start with conflicts, fix them, and afterwards get rid of MERGE_HEAD, with different error messages at each stage.

commit: do not complain of empty messages from -C When we pick another commit's message, we die() immediately if we find that it's empty and we are not going to run an editor (i.e., when running "-C" instead of "-c"). However, this check is redundant and harmful. It's redundant because we will already notice the empty message later, after we would have run the editor, and die there (just as we would for a regular, not "-C" case, where the user provided an empty message in the editor). It's harmful for a few reasons: 1. It does not respect --allow-empty-message. As a result, a "git rebase -i" cannot "pick" such a commit. So you cannot even go back in time to fix it with a "reword" or "edit" instruction. 2. It does not take into account other ways besides the editor to modify the message. For example, "git commit -C empty-commit -m foo" could take the author information from empty-commit, but add a message to it. There's more to do to make that work correctly (and right now we explicitly forbid "-C with -m"), but this removes one roadblock. 3. The existing check is not enough to prevent segfaults. We try to find the "\n\n" header/body boundary in the commit. If it is at the end of the string (i.e., no body), _or_ if we cannot find it at all (i.e., a truncated commit object), we consider the message empty. With "-C", that's OK; we die in either case. But with "-c", we continue on, and in the case of a truncated commit may end up dereferencing NULL+2. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Add the option "--ignore-submodules" to "git status" In some use cases it is not desirable that "git status" considers submodules that only contain untracked content as dirty. This may happen e.g. when the submodule is not under the developers control and not all build generated files have been added to .gitignore by the upstream developers. Using the "untracked" parameter for the "--ignore-submodules" option disables checking for untracked content and lets git diff report them as changed only when they have new commits or modified content. Sometimes it is not wanted to have submodules show up as changed when they just contain changes to their work tree (this was the behavior before 1.7.0). An example for that are scripts which just want to check for submodule commits while ignoring any changes to the work tree. Also users having large submodules known not to change might want to use this option, as the - sometimes substantial - time it takes to scan the submodule work tree(s) is saved when using the "dirty" parameter. And if you want to ignore any changes to submodules, you can now do that by using this option without parameters or with "all" (when the config option status.submodulesummary is set, using "all" will also suppress the output of the submodule summary). A new function handle_ignore_submodules_arg() is introduced to parse this option new to "git status" in a single location, as "git diff" already knew it.

Add the option "--ignore-submodules" to "git status" In some use cases it is not desirable that "git status" considers submodules that only contain untracked content as dirty. This may happen e.g. when the submodule is not under the developers control and not all build generated files have been added to .gitignore by the upstream developers. Using the "untracked" parameter for the "--ignore-submodules" option disables checking for untracked content and lets git diff report them as changed only when they have new commits or modified content. Sometimes it is not wanted to have submodules show up as changed when they just contain changes to their work tree (this was the behavior before 1.7.0). An example for that are scripts which just want to check for submodule commits while ignoring any changes to the work tree. Also users having large submodules known not to change might want to use this option, as the - sometimes substantial - time it takes to scan the submodule work tree(s) is saved when using the "dirty" parameter. And if you want to ignore any changes to submodules, you can now do that by using this option without parameters or with "all" (when the config option status.submodulesummary is set, using "all" will also suppress the output of the submodule summary). A new function handle_ignore_submodules_arg() is introduced to parse this option new to "git status" in a single location, as "git diff" already knew it.

commit: show interesting ident information in summary There are a few cases of user identity information that we consider interesting: (1) When the author and committer identities do not match. (2) When the committer identity was picked automatically from the username, hostname and GECOS information. In these cases, we already show the information in the commit message template. However, users do not always see that template because they might use "-m" or "-F". With this patch, we show these interesting cases after the commit, along with the subject and change summary.

builtin-commit: fix partial-commit support When making a partial-commit, we need to prepare two index files, one to be used to write out the tree to be committed (temporary index) and the other to be used as the index file after the commit is made. The temporary index needs to be initialized to HEAD and then all the named paths on the command line need to be staged on top of the index. For this, running add_files_to_cache() that compares what is in the index and the paths given from the command line is not enough -- the comparison will miss the paths that the user previously ran "git add" to the index since the HEAD because the index reset to the HEAD would not know about them. The index file needs to get the same modification done when preparing the temporary index as described above. This implementation mimics the behaviour of the scripted version of git-commit. It first runs overlay_tree_on_cache(), which was stolen from ls-files with the earlier change, to get the list of paths that the user can potentially mean, and then uses pathspec_match() to find which ones the user meant. This list of paths is used to update both the temporary and the real index file. Additional fixes are: - read the index file after pre-commit hook returns, as the hook can modify it to affect the contents of the commit. - remove the temporary index file .git/next-index-* after commit is done or aborted. - run post-commit hook with the real index file to be used after the commit (previously it gave the temporary commit if a partial commit was made). - resurrect the safety mechanism to refuse partial commits during a merge to match the scripted version.
