解决冲突
人生不如意之事十之八九,合并分支往往也不是一帆風(fēng)順的。
準(zhǔn)備新的feature1分支,繼續(xù)我們的新分支開發(fā):
$ git checkout -b feature1 Switched to a new branch 'feature1'修改readme.txt最后一行,改為:
Creating a new branch is quick AND simple.在feature1分支上提交:
$ git add readme.txt $ git commit -m "AND simple" [feature1 75a857c] AND simple 1 file changed, 1 insertion(+), 1 deletion(-)切換到master分支:
$ git checkout master Switched to branch 'master' Your branch is ahead of 'origin/master' by 1 commit.Git還會(huì)自動(dòng)提示我們當(dāng)前master分支比遠(yuǎn)程的master分支要超前1個(gè)提交。
在master分支上把readme.txt文件的最后一行改為:
Creating a new branch is quick & simple.提交:
$ git add readme.txt $ git commit -m "& simple" [master 400b400] & simple 1 file changed, 1 insertion(+), 1 deletion(-)現(xiàn)在,master分支和feature1分支各自都分別有新的提交,變成了這樣:
這種情況下,Git無法執(zhí)行“快速合并”,只能試圖把各自的修改合并起來,但這種合并就可能會(huì)有沖突,我們?cè)囋嚳?#xff1a;
$ git merge feature1 Auto-merging readme.txt CONFLICT (content): Merge conflict in readme.txt Automatic merge failed; fix conflicts and then commit the result.果然沖突了!Git告訴我們,readme.txt文件存在沖突,必須手動(dòng)解決沖突后再提交。git status也可以告訴我們沖突的文件:
$ git status # On branch master # Your branch is ahead of 'origin/master' by 2 commits. # # Unmerged paths: # (use "git add/rm <file>..." as appropriate to mark resolution) # # both modified: readme.txt # no changes added to commit (use "git add" and/or "git commit -a")我們可以直接查看readme.txt的內(nèi)容:
Git is a distributed version control system. Git is free software distributed under the GPL. Git has a mutable index called stage. Git tracks changes of files. <<<<<<< HEAD Creating a new branch is quick & simple. ======= Creating a new branch is quick AND simple. >>>>>>> feature1Git用<<<<<<<,=======,>>>>>>>標(biāo)記出不同分支的內(nèi)容,我們修改如下后保存:
Creating a new branch is quick and simple.再提交:
$ git add readme.txt $ git commit -m "conflict fixed" [master 59bc1cb] conflict fixed現(xiàn)在,master分支和feature1分支變成了下圖所示:
用帶參數(shù)的git log也可以看到分支的合并情況:
$ git log --graph --pretty=oneline --abbrev-commit * 59bc1cb conflict fixed |\ | * 75a857c AND simple * | 400b400 & simple |/ * fec145a branch test ...最后,刪除feature1分支:
$ git branch -d feature1 Deleted branch feature1 (was 75a857c).工作完成。
小結(jié)
當(dāng)Git無法自動(dòng)合并分支時(shí),就必須首先解決沖突。解決沖突后,再提交,合并完成。
用git log --graph命令可以看到分支合并圖。
?
貌似沒有看到有沖突:
第一次試驗(yàn)沒有沖突,重新在feature1分支上修改 提交,隨后跳轉(zhuǎn)到 master分支上再次進(jìn)行修改,然后提交,第三 用 merge 合并 feature1分支,出現(xiàn)沖突。
對(duì)文件進(jìn)行修改后,再次提交,commit ? conflict fixed 提交,然后處理沖突結(jié)束。
