You've made a ton of changes, tested them locally and want to get it live. Make sure all has been pushed to your repo and then:. Sometimes you have to change just one thing and don't want to do a complete redeployment. So go ahead, change your file and push it to your repo. Then on your local machine do:. Notice that the gem is the mysql gem and not the mysql2 gem.
The gem reference is also in the database. Notice that the adapter is mysql and not mysql2. Supposedly the dm-mysql-adapter does not suffer from the utf8 issue. This appears to be an issue with the DataMapper DataObject library.
Which of course does not exist. It's only a warning, but it disturbs me. If you try to use the mysql2 gem and adapter DataMapper barfs on the DataObject requires. When run, it attempts to require a mysql2 version of it's code. Skip to content. Star 1. Branches Tags. Could not load branches. Could not load tags. Latest commit. Git stats 20 commits.

This can lead to extracting arbitrary files into that location, thus allowing arbitrary file creation and overwrite. Additionally, a similar confusion could arise on case-insensitive filesystems. If a tar archive contained a directory at FOO , followed by a symbolic link named foo , then on case-insensitive file systems, the creation of the symbolic link would remove the directory from the filesystem, but not from the internal directory cache, as it would not be treated as a cache hit.
A subsequent file entry within the FOO directory would then be placed in the target of the symbolic link, thinking that the directory had already been created.
This logic is insufficient when extracting tar files that contain two directories and a symlink with names containing unicode values that normalized to the same value. Additionally, on Windows systems, long path portions would resolve to the same file system entities as their 8. A specially crafted tar archive can include directories with two forms of the path that resolve to the same file system entity, followed by a symbolic link with a name in the first form, lastly followed by a file using the second form.
This leads to bypassing node-tar symlink checks on directories, essentially allowing an untrusted tar file to symlink into an arbitrary location and extracting arbitrary files into that location. This is, in part, accomplished by sanitizing absolute paths of entries within the archive, skipping archive entries that contain..
Additionally, a.. Affected versions of this package are vulnerable to Arbitrary File Overwrite. This is due to insufficient symlink protection. This logic is insufficient when extracting tar files that contain both a directory and a symlink with the same name as the directory. This order of operations results in the directory being created and added to the node-tar directory cache. When a directory is present in the directory cache, subsequent calls to mkdir for that directory are skipped.
However, this is also where node-tar checks for symlinks occur. By first creating a directory, and then replacing that directory with a symlink, it is possible to bypass node-tar symlink checks on directories, essentially allowing an untrusted tar file to symlink into an arbitrary location and subsequently extracting arbitrary files into that location.
This is due to insufficient absolute path sanitization. This is achieved by stripping the absolute path root from any absolute file paths contained in a tar file. There are several options that you can add to each field. For example, if you want a field to be required, or unique, or have a default value, you can do that there.
Ruby and other languages has lambdas, which you could think of as a small function. This way, something like this:. Also, with Ruby 1. Previously, hashes looked like this:. You can still do this in 1. But, if you are using symbols as keys, you can do this instead:. How about foreign keys? DataMapper makes this real easy. We want a user to be able to have many posts, and a post to belong to a user.
