Jie Yu updated MESOS-7617: -------------------------- Affects Version/s: 1.3.1 > UCR cannot read docker images containing long file paths > -------------------------------------------------------- > > Key: MESOS-7617 > URL: https://issues.apache.org/jira/browse/MESOS-7617 > Project: Mesos > Issue Type: Bug > Components: containerization > Affects Versions: 1.1.2, 1.2.0, 1.3.0, 1.3.1 > Reporter: Chun-Hung Hsiao > Labels: containerizer, triaged > > The latest Docker uses go 1.7.5 > (https://github.com/moby/moby/blob/master/CHANGELOG.md#contrib-1), in which > the {{archive/tar}} package has a bug that cannot handle file paths longer > than 100 characters (https://github.com/golang/go/issues/17630). As a result, > Docker will generate images containing ill-formed tar files (details below) > when there are long paths. Docker itself understands the ill-formed image > fine, but a standard tar program will interpret the image as if all files > with long paths are placed under the root directory > (https://github.com/moby/moby/issues/29360). > This bug has been fixed in go 1.8, but since Docker is still using the bugged > version, we might need to handle these ill-formed images created by Dcoker > utilities. > NOTE: It is confirmed that the {{archive/tar}} package in go 1.8 cannot > correctly extract the ill-formed tar files, but the one in go 1.7.5 could. > Details: the {{archive/tar}} package uses {{USTAR}} format to handle files > with 100+-character-long paths (by only putting file name in the {{name}} > field and the path in the {{prefix}} field in the tar header), but uses > {{OLDGNU}}'s magic string, which does not understand the {{prefix}} field, so > a standard tar program will extract such files under the current directory. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
