portage.manifest: Fix mis-parsing Manifests with numerical checksums |
9 |
|
10 |
Fix the regular expression used to parse Manifests not to fail horribly |
11 |
when one of the checksums accidentally happens to be all-digits. |
12 |
|
13 |
The previously used regular expression used to greedily take everything |
14 |
up to the first number as filename. If one of the checksums happened to |
15 |
be purely numeric, this meant that everything up to that checksum was |
16 |
taken as filename, and the checksum itself was taken as file size. It |
17 |
was also capable of accepting an empty filename. |
18 |
|
19 |
The updated regular expression uses '\S+' to match filenames. Therefore, |
20 |
the match is terminated on first whitespace character and filenames can |
21 |
no longer contain spaces. Not that it could ever work reliably. |
