问题 Does the inserts are finished with the transaction commit? Or they can be finished later? 回答1: Per the MySQL Documentation: INSERT DELAYED works only with MyISAM, MEMORY, ARCHIVE, and (as of MySQL 5.1.19) BLACKHOLE tables. For engines that do not support DELAYED, an error occurs. None of these engines support transactions, so there's no conflict in functionality here. I would imagine that you will find that support of delayed inserts and transactions will be mutually exclusive. 回答2: Insert

问题 Let's say I have 5 local commits: commit 1 commit 2 commit 3 commit 4 commit 5 At this point when I'm working, I'd like to go back to commit 2. How would I do so? This was so easy using snapshots in previous versions of Xcode. "Discard changes" only goes back to commit 5, right? 回答1: In Xcode 9: Choose Source Control navigator. Select (branch) committed project. Click "Editor->Checkout ...", or click "Editor->Branch->Checkout ..." This works for me, it restores the entire project at once. 回答2

问题 You submit a pull request to merge Branch A into master. While this is pending (1 hour or so) and you want to use the pending features of branch A while you are waiting, you make Branch B Should Branch B be a branch off of Branch A or should Branch B be a branch off of master and then merge Branch A 回答1: Short answer : using another pullrequest can be dangerous. You still can develop your B feature then, there are 2 ways to do it: develop it in A branch and update your original pull-request,

问题 Sometimes, it makes sense to forbid git commit when there are untracked files, because you should add them either to files to commit or gitignore. And an option like -f to force this commit is also necessary. So is there any option/plugin/etc to do that? Thank you very much. 回答1: You can add a pre-commit hook that exits with a non-zero value if you find untracked files (you could examine the output of git status --porcelain -u to determine their presence--look for lines beginning with "?").

问题 I am new to Git, and I was trying to revert back to a previous commit in SourceTree. I right clicked on the commit I was going to revert to and then clicked checkout. It gave me a prompt saying that my working copy would become a detached head. What does this mean and is this something I should avoid? 回答1: As Per Git-Tower's Article : What's a "detached HEAD" in Git? Understanding how "checkout" works With the "git checkout" command, you determine which revision of your project you want to

问题 We use Tortoise SVN for source control, and have already set up a commit message template. I would also like to display some text to the user when they commit, that doesn't get included in their commit message, along the lines of "Don't forget to do X!". Is this possible? 回答1: I have set up a similar environment using the Tortoise Docs and can say: Yes, it is! Operation involves a Start-Commit Hook that fills in the lines that the user shall read and a Pre-Commit Hook that removes thee lines

问题 I committed files that I don't want to push. I didn't push yet. How can I remove the commit? This is how my screen looks: These are the options: I don't want to undo any changes to the source code! 回答1: To remove the commit without changing any source code, you need to perform a "mixed" reset. Right click on the last "good" commit (this will probably be origin/master ). Select "Reset current branch to this commit." In the resulting dialog, select "Mixed..." from the drop down and click OK.

问题 I did: git init git add . git rm -rf dirname Looking at other answsers, git reset --hard HEAD , git checkout -f and git reflog did not work, apparently because there is no HEAD to go back to, nor a commit to get the files back from. Is there a way to get the files back? 回答1: There is no way. Usually, git rm checks the files have already been committed before deleting them, so you don't lose any of your work. However, using -f overrides this check. In short: Don't use -f . Don't touch anything

问题 I'm having an issue committing changes to pickle types (lists) in sqlalchemy. It will act as if nothing happened after the committal. Here's my my function where I try to commit: def commit_move(game_id, player, move): game = game_query(game_id) if player == 'human': game.human_spaces.append(move) if player == 'ai': game.ai_spaces.append(move) game.available_spaces.remove(move) print game.human_spaces print game.ai_spaces print game.available_spaces print "----" session.add(game) session

问题 I know how to remove a specific commit from the git history with git rebase --interactive . My question concerns the more complex case with a history like this: A--X--B--C--D \ E--F where I would like to remove the commit X . The issue is that in this case there are two or more branches with parents ( B in this case) that have X in their history, so a single git rebase -i will not do the trick (at least I do not know how). Is there a simple way to remove X , or do I have to rely on rebasing
