在git svn的时候使用，提交记录的时候，有部分文件的修改不需要commit。
在向svn进行git svn dcommit的时候，必须保存本地目录是clean的。所以需要进行stash，然后在dcommit
dcommit之后，需要在git stash aply
之前一直都在使用git stash 以及git stash apply
但是一直没有深入的研究，今天发现git stash是是会覆盖掉之前的stash的[stash apply仅仅取出最近的一次stash]
git stash --help 查看帮助手册
Use git stash when you want to record the current state of the working directory and the index, but want to go back to a clean working directory. The command saves your local modifications away and reverts the working directory to match the HEAD commit.
The modifications stashed away by this command can be listed with git stash list, inspected with git stash show, and restored (potentially on top of a different commit) with git stash apply. Calling git stash without any arguments is equivalent to git stash save. A stash is by default listed as "WIP on branchname …", but you can give a more descriptive message on the command line when you create one.
The latest stash you created is stored in refs/stash; older stashes are found in the reflog of this reference and can be named using the usual reflog syntax (e.g. stash@{0} is the most recently created stash, stash@{1} is the one before it,stash@{2.hours.ago} is also possible).
git stash list
查看之前缓存的所有stash
$ git stash list
stash@{0}: WIP on temp: 36b0f5f 删除HSDataFrameManager类中多余的代码 //第二次的stash，覆盖了第一次【git stash apply的时候，只能出现这一次的，上一次的不会出现】
stash@{1}: WIP on temp: 36b0f5f 删除HSDataFrameManager类中多余的代码 //第一次的stash
stash@{2}: WIP on temp: c723e17 接收到消息的时候，打印出消息类型，如果消息内部有
stash@{3}: WIP on temp: 18fa2a3 连接通讯模块时，需要将主窗体的窗口句柄传递给通讯
temp是分支的名字
第0个和第1个虽然看起来完全一样，但实际上是不同的
git stash show
查看list中的某一次stash
$ git stash show stash@{0}
ZBMYun/SourceCode/ZITakerHS/ZITaker/SystemConfig.ini | 2 +-
1 file changed, 1 insertion(+), 1 deletion(-)
$ git stash show stash@{1}
ZBMYun/SourceCode/ZITakerHS/ZITaker/UI/Main.cs | 2 +-
ZBMYun/SourceCode/ZITakerHS/ZITaker/ZbmStorage_Component.ini | 2 +-
2 files changed, 2 insertions(+), 2 deletions(-)
git stash show stash@{0} -u
添加-u参数可以输出某一次stash的所有文件差异对比
git stash apply
可以apply指定的stash，如果你不指定的话，默认apply最近一次的stash
If you want to apply one of the older stashes, you can specify it by naming it, like this: git stash apply stash@{2}.
If you don’t specify a stash, Git assumes the most recent stash and tries to apply it:
git stash drop
$ git stash list
stash@{0}: WIP on local: 63b9f1b DebugInfoManager类，在FormMain加载的时候需要主
stash@{1}: WIP on svn: 78ab728 设备第一次上线后，直接发送采集数据，在这种情况下
$ git stash drop stash@{0}
Dropped stash@{0} (1136bc142780259d8541c7e3a605ff2250cc9427)
pop [--index] [-q|--quiet] [<stash>]
Remove a single stashed state from the stash list and apply it on top of the current working tree state, i.e., do the inverse operation of git stash save. The working directory must match the index.
Applying the state can fail with conflicts; in this case, it is not removed from the stash list. You need to resolve the conflicts by hand and call git stash drop manually afterwards.
If the --index option is used, then tries to reinstate not only the working tree’s changes, but also the index’s ones. However, this can fail, when you have conflicts (which are stored in the index, where you therefore can no longer apply the changes as they were originally).
When no <stash> is given, stash@{0} is assumed, otherwise <stash> must be a reference of the form stash@{<revision>}.
Options:
save [-p|--patch] [-k|--[no-]keep-index] [-u|--include-untracked] [-a|--all] [-q|--quiet] [<message>]
Save your local modifications to a new stash, and run git reset --hard to revert them.
The <message> part is optional and gives the description along with the stashed state.
For quickly making a snapshot, you can omit both "save" and <message>, but giving only <message> does not trigger this action to prevent a misspelled subcommand from making an unwanted stash.
If the --keep-index option is used, all changes already added to the index are left intact.
If the --include-untracked option is used, all untracked files are also stashed and then cleaned up with git clean, leaving the working directory in a very clean state.
If the --all option is used instead then the ignored files are stashed and cleaned in addition to the untracked files.
