a shell object that can chdir, setenv, and exec commands.
(note that this executes stuff after fork, so permanent changes are cheap
and okay)
Also create it from "host" objects, which simplifies parameter passing.
(it's easy to distinguish between a file and a directory under ports).
expand sequences for those files and hosts
when restarting dpb, kill locks that don't correspond to errors, but to a dpb
running on the same host that's no longer there.
do __WARN__ like __DIE__
option -DDONT_BUILD_ONCE
option -DDONT_CLEAN_LOCKS
document some
tree may want to weed distfiles too, so allow for a full scan of the tree
without building/fetching anything, just to update history:
dpb -DHISTORY_ONLY
(just requires making sure the right engines are created, and a very shortened
loop at end waiting for history to be updated).
remove a few explicit (and implicit) die from Fetch: missing/out-of-sync
distinfo no longer kill dpb, instead they're properly reported as broken
paths and things still go on (note that even a missing SUPDISTFILE checksum
*will* mark a path as broken, that's totally intentional)
the names of files in there are not totally trivial to figure out from the
normal filename + sha.
-> filename will be stripped off DIST_SUBDIR
-> b64 checksums interfere with filesystem semantics, e.g., /u8//ffg
will become u8/ffg
- keep a stash indexed by checksum, so dpb can identify duplicate files.
- in a full bulk, if the scan has no errors, write to a ${DISTDIR}/history
file the files encountered in ${DISTDIR}/distinfo that seem to no longer
be needed (with full timestamp and checksum info).
Should be enough info to know when to expire old DISTDIR entries.
- keep a cache of checked checksums as ${DISTDIR}/distinfo
- read existing cache on startup, don't need to recheck those files.
- split checksum_task: update the cache after the checksum is done
- create the by_cipher/sha256/... entries
- in fetch_only mode, do a "long" checksum on existing files not in the cache.
If you ever have doubts on the integrity of already checked files, just
rm ${DISTDIR}/distinfo.
building, like bsd.port.mk does.
won't change anything in the build, but makes pkg_add -a less confusing,
since mp ports won't try to add itself while building.0
if no-depends but that's complicated)
also, two distinct critical sections: we don't need to stay locked at
the end of show-prepare-result.
Even though that's not really important, simplify logic a wee little bit
