\featurelabel{mtime-preserve} |
| 69 |
In EAPIs listed in table~\ref{tab:mtime-preserve}, the package manager |
| 70 |
must preserve modification times of regular files. This includes files |
| 71 |
being compressed before merging. Exceptions to this are files newly |
| 72 |
created by the package manager and binary object files being stripped |
| 73 |
of symbols. |
| 74 |
|
| 75 |
The integer seconds part of the modification time is guaranteed to be |
| 76 |
preserved. The package manager may also preserve sub-second |
| 77 |
timestamps; in this case, the full precision available with the |
| 78 |
underlying operating system, filesystems, and programming language |
| 79 |
must be used. Timestamps of all files installed in the same |
| 80 |
destination filesystem must be handled in a consistent way, especially |
| 81 |
their ordering must be preserved. |
| 82 |
|
| 83 |
In other EAPIs, the behaviour with respect to file modification times |
| 84 |
is undefined. |
