I did receive this one. In case some of you haven't received the first one |
| 10 |
either, I'm quoting it here (and note the updated location above): |
| 11 |
|
| 12 |
I ported Stuart's confcache patch from portage .50 to .51_rc7 (hope cvs head |
| 13 |
isn't too different...). I also made a few changes and fixes - see attached |
| 14 |
changelog if you used the orig patch. |
| 15 |
|
| 16 |
What this does: it keeps a central cache for autoconf-generated configure |
| 17 |
scripts in /var/tmp. When econf is called, it checks the cache's validity |
| 18 |
against a list of files & md5sums. If any files have changed, the entire |
| 19 |
cache is cleared. |
| 20 |
|
| 21 |
During configure's run, the sandbox logs all files accessed. There is a small |
| 22 |
patch to libsandbox.c, unchanged from Stuart's version, to allow this. Then, |
| 23 |
the file/md5sum list is updated. The sandbox log then has to be manually |
| 24 |
fixed up to remove these entries. |
| 25 |
|
| 26 |
Ebuild-side: FEATURES+=confcache enables this. Either use econf, or call |
| 27 |
confcache_start and confcache_stop before and after your configure run. |
| 28 |
confcache_start adds the --with-cache=foo parameter to $ECONF_EXTRA; pass |
| 29 |
that to configure. |
| 30 |
|
| 31 |
Embedded people: I've been asked to keep a separate cache for every |
| 32 |
combination of $CHOST, $CBUILD, $THOST. Please confirm that's how you want |
| 33 |
it. |
| 34 |
|
| 35 |
Myself, I need it to speed up the upcoming split kde ebuilds (eg separate |
| 36 |
ebuilds for konqueror etc rather than one big kdebase ebuild). |
| 37 |
|
| 38 |
Stuart, I hope you're ok with my changes. Basically they just consist of |
| 39 |
updating the patch for the new version's ebuild.sh and fixing a couple of |
| 40 |
bugs. |
| 41 |
|
| 42 |
Comments welcome (my first patch to portage, hope it works :-). Credit goes to |
| 43 |
Stuart, bugs to me (except for sandbox). |
