2015-08-12Merge branch 'dt/unpack-trees-cache-tree-revalidate'Libravatar Junio C Hamano2-0/+32
The code to perform multi-tree merges has been taught to repopulate the cache-tree upon a successful merge into the index, so that subsequent "diff-index --cached" (hence "status") and "write-tree" (hence "commit") will go faster. The same logic in "git checkout" may now be removed, but that is a separate issue. * dt/unpack-trees-cache-tree-revalidate: unpack-trees: populate cache-tree on successful merge

2015-08-05tests: fix cleanup after tests in t1509-root-worktreeLibravatar Patrick Steinhardt1-1/+1
During cleanup we do a simple 'rm /*' to remove leftover files from previous tests. As 'rm' errors out when there is anything it cannot delete and there are directories present at '/' it will throw an error, causing the '&&' chain to fail. Fix this by explicitly removing the files.

2015-08-04builtin-am: remove redirection to git-am.shLibravatar Paul Tan4-22/+1
At the beginning of the rewrite of git-am.sh to C, in order to not break existing test scripts that depended on a functional git-am, a redirection to git-am.sh was introduced that would activate if the environment variable _GIT_USE_BUILTIN_AM was not defined. Now that all of git-am.sh's functionality has been re-implemented in builtin/am.c, remove this redirection, and retire git-am.sh into contrib/examples/.

2015-08-04builtin-am: check for valid committer identLibravatar Paul Tan1-0/+3
When commit_tree() is called, if the user does not have an explicit committer ident configured, it will attempt to construct a default committer ident based on the user's and system's info (e.g. gecos field, hostname etc.) However, if a default committer ident is unable to be constructed, commit_tree() will die(), but at this point of git-am's execution, there will already be changes made to the index and work tree. This can be confusing to new users, and as such since d64e6b0 (Keep Porcelainish from failing by broken ident after making changes., 2006-02-18) git-am.sh will check to see if the committer ident has been configured, or a default one can be constructed, before even starting to apply patches.

2015-08-04builtin-am: implement legacy -b/--binary optionLibravatar Paul Tan1-0/+7
The -b/--binary option was initially implemented in 087b674 (git-am: --binary; document --resume and --binary., 2005-11-16). The option will pass the --binary flag to git-apply to allow it to apply binary patches. However, in 2b6eef9 (Make apply --binary a no-op., 2006-09-06), --binary was been made a no-op in git-apply. Following that, since cb3a160 (git-am: ignore --binary option, 2008-08-09), the --binary option in git-am is ignored as well. In 6c15a1c (am: officially deprecate -b/--binary option, 2012-03-13), the --binary option was tweaked to its present behavior: when set, the message: The -b/--binary option has been a no-op for long time, and it will be removed. Please do not use it anymore. will be printed. Re-implement this in builtin/am.c. Signed-off-by: Paul Tan <pyokagan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-08-04builtin-am: implement -i/--interactiveLibravatar Paul Tan1-1/+104
Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am.sh supported the --interactive mode. After parsing the patch mail and extracting the patch, commit message and authorship info, an interactive session will begin that allows the user to choose between: * applying the patch * applying the patch and all subsequent patches (by disabling interactive mode in subsequent patches) * skipping the patch * editing the commit message Since f89ad67 (Add [v]iew patch in git-am interactive., 2005-10-25), git-am.sh --interactive also supported viewing the patch to be applied. When --resolved-ing in --interactive mode, we need to take care to update the patch with the contents of the index, such that the correct patch will be displayed when the patch is viewed in interactive mode.

Since 0cfd112 (am: preliminary support for hg patches, 2011-08-29), git-am.sh could convert mercurial patches to an RFC2822 mail patch suitable for parsing with git-mailinfo, and queue them in the state directory for application. Since 15ced75 (git-am foreign patch support: autodetect some patch formats, 2009-05-27), git-am.sh was able to auto-detect mercurial patches by checking if the file begins with the line: # HG changeset patch Re-implement the above in builtin/am.c.

Since c574e68 (git-am foreign patch support: StGIT support, 2009-05-27), git-am.sh is able to read a single StGit series file and, for each StGit patch listed in the file, convert the StGit patch into a RFC2822 mail patch suitable for parsing with git-mailinfo, and queue them in the state directory for applying. Since 15ced75 (git-am foreign patch support: autodetect some patch formats, 2009-05-27), git-am.sh is able to auto-detect StGit series files by checking to see if the file starts with the string: # This series applies on GIT commit Re-implement the above in builtin/am.c.

2015-08-04builtin-am: support and auto-detect StGit patchesLibravatar Paul Tan1-1/+131
Since c574e68 (git-am foreign patch support: StGIT support, 2009-05-27), git-am.sh supported converting StGit patches into RFC2822 mail patches that can be parsed with git-mailinfo. Implement this by introducing two functions in builtin/am.c: stgit_patch_to_mail() and split_mail_conv(). stgit_patch_to_mail() is a callback function for split_mail_conv(), and contains the logic for converting an StGit patch into an RFC2822 mail patch. split_mail_conv() implements the logic to go through each file in the `paths` list, reading from stdin where specified, and calls the callback function to write the converted patch to the corresponding output file in the state directory. This interface should be generic enough to support other foreign patch formats in the future. Since 15ced75 (git-am foreign patch support: autodetect some patch formats, 2009-05-27), git-am.sh is able to auto-detect StGit patches. Re-implement this in builtin/am.c.

2015-08-04builtin-am: rerere supportLibravatar Paul Tan1-0/+25
git-am.sh will call git-rerere at the following events: * "git rerere" when a three-way merge fails to record the conflicted automerge results. Since 8389b52 (git-rerere: reuse recorded resolve., 2006-01-28) * Since cb6020b (Teach --[no-]rerere-autoupdate option to merge, revert and friends, 2009-12-04), git-am.sh supports the --[no-]rerere-autoupdate option as well, and would pass it to git-rerere. * "git rerere" when --resolved, to record the hand resolution. Since f131dd4 (rerere: record (or avoid misrecording) resolved, skipped or aborted rebase/am, 2006-12-08) * "git rerere clear" when --skip-ing. Since f131dd4 (rerere: record (or avoid misrecording) resolved, skipped or aborted rebase/am, 2006-12-08) * "git rerere clear" when --abort-ing.

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am.sh will invoke the post-applypatch hook after the patch is applied and a commit is made. The exit code of the hook is ignored.

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am.sg will invoke the pre-applypatch hook after applying the patch to the index, but before a commit is made.

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am.sh will invoke the applypatch-msg hooks just after extracting the patch message.

Since eb2151b (rebase: support automatic notes copying, 2010-03-12), git-am.sh supported automatic notes copying in --rebasing mode by invoking "git notes copy" once it has finished applying all the patches.

Since 96e1948 (rebase: invoke post-rewrite hook, 2010-03-12), git-am.sh will invoke the post-rewrite hook after it successfully finishes applying all the queued patches. To do this, when parsing a mail to extract its patch and metadata, in --rebasing mode git-am.sh will also store the original commit ID in the $state_dir/original-commit file. Once it applies and commits the patch, the original commit ID, and the new commit ID, will be appended to the $state_dir/rewritten file. Once all of the queued mail have been processed, git-am.sh will then invoke the post-rewrite hook with the contents of the $state_dir/rewritten file. Re-implement this in builtin/am.c.

Since 3b4e395 (am: add the --gpg-sign option, 2014-02-01), git-am.sh supported the --gpg-sign option, and would pass it to git-commit-tree, thus GPG-signing the commit object. Re-implement this option in builtin/am.c. git-commit-tree would also sign the commit by default if the commit.gpgsign setting is true.

Re-implement support for this option in builtin/am.c.

Since e80d4cb (git-am: Add am.keepcr and --no-keep-cr to override it, 2010-02-27), git-am.sh supported the am.keepcr config setting, which controls whether --keep-cr is on by default.

2015-08-04builtin-am: bypass git-mailinfo when --rebasingLibravatar Paul Tan1-1/+133
Since 5e835ca (rebase: do not munge commit log message, 2008-04-16), git am --rebasing no longer gets the commit log message from the patch, but reads it directly from the commit identified by the "From " header line. Since 43c2325 (am: use get_author_ident_from_commit instead of mailinfo when rebasing, 2010-06-16), git am --rebasing also gets the author name, email and date directly from the commit. Since 0fbb95d (am: don't call mailinfo if $rebasing, 2012-06-26), git am --rebasing does not use git-mailinfo to get the patch body, but rather generates it directly from the commit itself. The above 3 commits introduced a separate parse_mail() code path in git-am.sh's --rebasing mode that bypasses git-mailinfo. Re-implement this code path in builtin/am.c as parse_mail_rebase().

2015-08-04builtin-am: implement --rebasing modeLibravatar Paul Tan1-4/+26
Since 3041c32 (am: --rebasing, 2008-03-04), git-am.sh supported the --rebasing option, which is used internally by git-rebase to tell git-am that it is being used for its purpose. It would create the empty file $state_dir/rebasing to help "completion" scripts tell if the ongoing operation is am or rebase. As of 0fbb95d (am: don't call mailinfo if $rebasing, 2012-06-26), --rebasing also implies --3way as well. Since a1549e1 (am: return control to caller, for housekeeping, 2013-05-12), git-am.sh would only clean up the state directory when it is not --rebasing, instead deferring cleanup to git-rebase.sh. Re-implement the above in builtin/am.c. Signed-off-by: Paul Tan <pyokagan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-08-04builtin-am: implement --3wayLibravatar Paul Tan1-4/+150
Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am.sh supported the --3way option, and if set, would attempt to do a 3-way merge if the initial patch application fails. Since 5d86861 (am -3: list the paths that needed 3-way fallback, 2012-03-28), in a 3-way merge git-am.sh would list the paths that needed 3-way fallback, so that the user can review them more carefully to spot mismerges. Re-implement the above in builtin/am.c. Signed-off-by: Paul Tan <pyokagan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-08-04cache-tree: introduce write_index_as_tree()Libravatar Paul Tan2-12/+18
A caller may wish to write a temporary index as a tree. However, write_cache_as_tree() assumes that the index was read from, and will write to, the default index file path. Introduce write_index_as_tree() which removes this limitation by allowing the caller to specify its own index_state and index file path.

2015-08-04builtin-am: implement -s/--signoffLibravatar Paul Tan1-0/+12
Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), git-am supported the --signoff option which will append a signoff at the end of the commit messsage. Re-implement this feature in parse_mail() by calling append_signoff() if the option is set. Signed-off-by: Paul Tan <pyokagan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-08-04builtin-am: exit with user friendly message on failureLibravatar Paul Tan1-4/+26
Since ced9456 (Give the user a hint for how to continue in the case that git-am fails because it requires user intervention, 2006-05-02), git-am prints additional information on how the user can re-invoke git-am to resume patch application after resolving the failure. Re-implement this through the die_user_resolve() function. Since cc12005 (Make git rebase interactive help match documentation., 2006-05-13), git-am supports the --resolvemsg option which is used by git-rebase to override the message printed out when git-am fails. Re-implement this option. Signed-off-by: Paul Tan <pyokagan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
