2019-03-07rebase--interactive: move rearrange_squash_in_todo_file()Libravatar Alban Gruin1-1/+27
As rearrange_squash_in_todo_file() is only needed inside of rebase--interactive.c for `rebase -p', it is moved there from sequencer.c. The parameter r (repository) is dropped along the way, and the error handling is slightly improved.

2019-03-07sequencer: change complete_action() to use the refactored functionsLibravatar Alban Gruin1-14/+6
complete_action() used functions that read the todo-list file, made some changes to it, and wrote it back to the disk. The previous commits were dedicated to separate the part that deals with the file from the actual logic of these functions. Now that this is done, we can call directly the "logic" functions to avoid useless file access. The parsing of the list has to be done by the caller. If the buffer of the todo list provided by the caller is empty, a `noop' command is directly added to the todo list, without touching the buffer.

2019-03-07sequencer: make sequencer_make_script() write its script to a strbufLibravatar Alban Gruin1-5/+8
This makes sequencer_make_script() write its script to a strbuf (ie. the buffer of a todo_list) instead of a FILE. This reduce the amount of read/write made by rebase interactive. Signed-off-by: Alban Gruin <alban.gruin@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-03-07sequencer: refactor rearrange_squash() to work on a todo_listLibravatar Alban Gruin1-1/+1
This refactors rearrange_squash() to work on a todo_list to avoid redundant reads and writes. The function is renamed todo_list_rearrange_squash(). The old version created a new buffer, which was directly written to the disk. This new version creates a new item list by just copying items from the old item list, without creating a new buffer. This eliminates the need to reparse the todo list, but this also means its buffer cannot be directly written to the disk. As rebase -p still need to check the todo list from the disk, a new function is introduced, rearrange_squash_in_todo_file(). complete_action() still uses rearrange_squash_in_todo_file() for now. This will be changed in a future commit. Signed-off-by: Alban Gruin <alban.gruin@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-03-07sequencer: refactor sequencer_add_exec_commands() to work on a todo_listLibravatar Alban Gruin1-4/+14
This refactors sequencer_add_exec_commands() to work on a todo_list to avoid redundant reads and writes to the disk. Instead of inserting the `exec' commands between the other commands and re-parsing the buffer at the end, they are appended to the buffer once, and a new list of items is created. Items from the old list are copied across and new `exec' items are appended when necessary. This eliminates the need to reparse the buffer, but this also means we have to use todo_list_write_to_disk() to write the file. todo_list_add_exec_commands() and sequencer_add_exec_commands() are modified to take a string list instead of a string -- one item for each command. This makes it easier to insert a new command to the todo list for each command to execute. sequencer_add_exec_commands() still reads the todo list from the disk, as it is needed by rebase -p. complete_action() still uses sequencer_add_exec_commands() for now. This will be changed in a future commit. Signed-off-by: Alban Gruin <alban.gruin@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-01-29sequencer: refactor check_todo_list() to work on a todo_listLibravatar Alban Gruin1-1/+1
This refactors check_todo_list() to work on a todo_list to avoid redundant reads and writes to the disk. The function is renamed todo_list_check(). The parsing of the two todo lists is left to the caller. As rebase -p still need to check the todo list from the disk, a new function is introduced, check_todo_list_from_file(). It reads the file from the disk, parses it, pass the todo_list to todo_list_check(), and writes it back to the disk. As get_missing_commit_check_level() and the enum missing_commit_check_level are no longer needed inside of sequencer.c, they are moved to rebase-interactive.c, and made static again.

2019-01-29sequencer: refactor transform_todos() to work on a todo_listLibravatar Alban Gruin1-1/+1
This refactors transform_todos() to work on a todo_list. The function is renamed todo_list_transform(). As rebase -p still need to check the todo list from the disk, a new function is introduced, transform_todo_file(). It is still used by complete_action() and edit_todo_list() for now, but they will be replaced in a future commit. todo_list_transform() is not a static function, because it will be used by edit_todo_list() from rebase-interactive.c in a future commit.

2018-11-12sequencer.c: remove implicit dependency on the_repositoryLibravatar Nguyễn Thái Ngọc Duy1-5/+6
Note that the_hash_algo stays, even if we can easily replace it with repo->hash_algo. My reason is I still believe tying hash_algo to a struct repository is a wrong move. But if I'm wrong, we can always go for another round of conversion. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-11-12sequencer.c: remove implicit dependency on the_indexLibravatar Nguyễn Thái Ngọc Duy1-2/+2
Since we're going to pass 'struct repository *' around most of the time instead of 'struct index_state *' because most sequencer.c operations need more than just the index, the_repository is replaced as well in the functions that now take 'struct repository *'. the_repository is still present in this file, but total clean up will be done later. It's not the main focus of this patch. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-10-09rebase -i: move rebase--helper modes to rebase--interactiveLibravatar Alban Gruin1-1/+26
This moves the rebase--helper modes still used by git-rebase--preserve-merges.sh (`--shorten-ids`, `--expand-ids`, `--check-todo-list`, `--rearrange-squash` and `--add-exec-commands`) to rebase--interactive.c. git-rebase--preserve-merges.sh is modified accordingly, and rebase--helper.c is removed as it is useless now.
