更好的方式`chowning`未知的uid / gid的文件`rsync`（包括一个--exclude-from文件）将考虑作为源文件

问题描述

我试图更改未知的uid和gid的文件，我的 rsync 命令将考虑作为源文件，然后执行我的 rsync 命令。

I am trying to change unknown uid's and gid's on files that my rsync command would consider as source files before I execute my rsync command.

我的 rsync 命令包含排除文件。

My rsync command includes an exclude file.

我需要这样做的原因在我的问题）

Download the latest rsync source tar file at rsync site

我已解压缩到

我下载了 Eclipse 以用作IDE，但您只需修改文件与 NotePad ++ 如下：

I downloaded Eclipse to use as an IDE but you could just modify the files with NotePad++ as follows:

在main.c文件中添加了一个信息行，运行rsync，以便您知道您正在使用您的个人rsync版本。我相信，还有一个适当的方式设置版本号为我自己的一个，但我会让有人评论如何做到这一点。 （所有我的行以/ * dalek * /结尾）：

In the main.c file I added an information line that you see every time you run rsync so you know you are using your personal rsync version. I am sure that there is also an appropriate way to set the version number to one of my own but I will let someone comment on how to do that. (all my lines end with /* dalek */):

starttime = time(NULL);
our_uid = MY_UID();
our_gid = MY_GID();

rprintf(FINFO,"rsync 3.1.1 with edits started by uid: %u gid: %u\n", our_uid, our_gid ); /* dalek */

然后，在flist.c中，添加我的/ * dalek * / lines

Then, in flist.c, add my /* dalek */ lines as follows:

if (!preserve_uid || ((uid_t)F_OWNER(file) == uid && *lastname))
    xflags |= XMIT_SAME_UID;
else {
    uid = F_OWNER(file);

    if (uid==4294967295){                                                                      /* dalek */
        if (do_lchown(fname, our_uid, F_GROUP(file)) != 0) {                                   /* dalek */
            rprintf(FINFO, "COULD NOT CHANGE 4294967295 UID to %u on %s\n",our_uid,fname);     /* dalek */
        }else{                                                                                 /* dalek */
            uid=our_uid;                                                                       /* dalek */
        }                                                                                      /* dalek */
    }                                                                                          /* dalek */

    if (!numeric_ids) {
        user_name = add_uid(uid);
        if (inc_recurse && user_name)
            xflags |= XMIT_USER_NAME_FOLLOWS;
    }
}
if (!preserve_gid || ((gid_t)F_GROUP(file) == gid && *lastname))
    xflags |= XMIT_SAME_GID;
else {
    gid = F_GROUP(file);

    if (gid==4294967295){                                                                      /* dalek */
        if (do_lchown(fname, F_OWNER(file), our_gid) != 0) {                                   /* dalek */
            rprintf(FINFO, "COULD NOT CHANGE 4294967295 GID to %u on %s\n",our_gid,fname);     /* dalek */
        }else{                                                                                 /* dalek */
            gid=our_gid;                                                                       /* dalek */
        }                                                                                      /* dalek */
    }                                                                                          /* dalek */

    if (!numeric_ids) {
        group_name = add_gid(gid);
        if (inc_recurse && group_name)
            xflags |= XMIT_GROUP_NAME_FOLLOWS;
    }
}

然后在最近添加的rsync源目录中运行 ./ configure.sh 然后运行 make ，然后运行 make install 。这就对了！你应该在... / usr / local / bin中有一个新的rsync.exe文件，当你使用rsync从现在开始，因为cygwin放置... / usr / local / bin在... / bin之前它使用的PATH。原始rsync仍在... / bin中。要使用原始文件，只需将修改的rsync.exe移出/ usr / local / bin。

Then in your recently added rsync source directory run ./configure.sh then run make then run make install. That is it! You should have a new rsync.exe file in .../usr/local/bin which will be run whenever you use rsync from now on since cygwin puts .../usr/local/bin ahead of .../bin in the PATH it uses. The original rsync is still in .../bin. To use the original, just move your modified rsync.exe out of .../usr/local/bin.
