Dan has been the porthole developer that has done the most integrating |
| 9 |
portage modules for porthole's use, but it looks like we are loosing him |
| 10 |
from gentoo for now. I have not had much reason to think about how much |
| 11 |
more we might need from portage. |
| 12 |
|
| 13 |
|
| 14 |
|
| 15 |
Portage modules/variables currently used directly by Porthole: |
| 16 |
|
| 17 |
portage.grabfile():: used for obtaining [keywords.desc, use.desc, use.local.desc] |
| 18 |
|
| 19 |
portage.config(clone=portage.settings).environ()[var] :: where var = 1 of ['PORTDIR_OVERLAY','PORTDIR', "USE"] |
| 20 |
|
| 21 |
portage.auxdbkeys |
| 22 |
|
| 23 |
"""Extract installed versions from full name.""" |
| 24 |
return portage.db['/']['vartree'].dep_match(full_name) |
| 25 |
|
| 26 |
portage.db['/']['porttree'].getallnodes() |
| 27 |
|
| 28 |
portage.db['/']['vartree'].getallnodes() |
| 29 |
|
| 30 |
portage.catpkgsplit(ebuild) |
| 31 |
|
| 32 |
portage.portdb.aux_get(ebuild, [property])[0] |
| 33 |
|
| 34 |
portage.best(versions) |
| 35 |
|
| 36 |
# showing complete porthole function for (possibly) more clarity |
| 37 |
def get_properties(ebuild): |
| 38 |
"""Get all ebuild variables in one chunk.""" |
| 39 |
return Properties(dict(zip(keys, |
| 40 |
portage.portdb.aux_get(ebuild, |
| 41 |
portage.auxdbkeys)))) |
| 42 |
|
| 43 |
|
| 44 |
def get_versions(self, include_masked = True): |
| 45 |
"""Returns all versions of the available ebuild""" |
| 46 |
# Note: this slow, especially when include_masked is false |
| 47 |
criterion = include_masked and 'match-all' or 'match-visible' |
| 48 |
return portage.portdb.xmatch(criterion, self.full_name) |

Wish list: |

Portages version comparison/handling code from bug: http://bugs.gentoo.org/show_bug.cgi?id=37406 |
| 57 |
was would be implemented soon. I see browsing thru 2.0.51_rc9 that it is not yet implemented. |
| 58 |
If it is being implemented Porthole should use the following from portage's code: |
| 59 |
|
| 60 |
ver_regexp = re.compile("^(cvs-)?(\\d+)((\\.\\d+)*)([a-zA-Z]?)((_(pre|p|beta|alpha|rc)\\d*)*)(-r(\\d+))?$") |
| 61 |
suffix_regexp = re.compile("^(alpha|beta|rc|pre|p)(\\d*)$") |
| 62 |
# modified portage comparison suffix values for sorting in desired precedence |
| 63 |
suffix_value = {"alpha": '0', "beta": '1', "pre": '2', "rc": '3', "p": '4'} |
| 64 |
|
| 65 |
That would allow porthole's modified version of that code to follow any changes in portage's values. |
