which will delete any .apk package on output directory that were
not downloaded by fetch
this allows apk fetch to incrementally build repositories for
binary images

don't overwrite the link_target if it was found from pax header.

- self-conflicts when the exact same version of a name is provided
twice is now properly detected and diagnozed
- don't print redundant satisfies diagnostic

Implement --no-cache. The index is read directly from network and not
cached. This is useful for docker, where you install a set of packages
and directly after purge the cache. (see
https://github.com/gliderlabs/docker-alpine/blob/1fc9e59d1689fc4eaf930ec66389fe58062fccec/builder/scripts/apk-install)

preserve [am]time for all packages and indexes. this fixes the caching
error that 'apk update' is after new index is generated, but before
the used mirror is synchronized. this caused local apkindex timestamp
to be newer than file in mirror, when in fact it was outdated index.
this also fixes fetched files to have build timestamp so that files
going to .iso or custom images have proper timestamps (rsync with
appropriate --modify-window now works)

fixes #4770
apk_name_foreach_matching() can matches each package via it's
main name and all it's provides. Print matched packages only once.
|

We need fall back to a splice buffer if posix_fallocate call fails due
to file being a device (eg tty) or a pipe. This fixes apk fetch --stdout.

ftruncate does not allocate it, and subsequent access to mmaped
file will result in SIGBUS. this fixes to properly report disk
full errors.

the problem is that var/lock is on root installs symlink to /run/lock
(on tmpfs) and does not exist if doing chroot() to that root. fixes
apk to work when chrooted to existing rootfs install.

it's a hot path for decoding checksums in fdb
|
|
it is more efficient than the previously used djb hash

resolve reverse dependencies after all packages have been loaded,
and avoid traversing the reverse name lists. now that we use
automatic virtual packages (soname, pkg-config, etc.) the reverse
dependency chains can become considerable longer than what it was
when the rdependency construction code was originally written.

commit 941fc1b1 uncovered a bug that directory permissions are
not updated properly at db load time if it's the default acl.

In practice this should fix to e.g. not wipe out /etc/apk/world if
final flush to /etc/apk/world.new fails.
This was prompted by an incident the other day where I ran the root
partition of an Alpine box out of space using 'apk add', and apk
helpfully wiped the contents of /etc/apk/world at the same time.
It might be tricky to try to reproduce exactly the same failure,
but from an examination of the code, setting 'rc' before the final
call to fdo_flush rather than after is one possible cause of this
behavior. (If the entire contents of /etc/apk/world.new are buffered,
and all get written out in the final fdo_flush call, and that call
fails, fdo_close will still happily rename /etc/apk/world.new to
/etc/apk/world.)

the security implications are not as high as compared to regular
tar/unzip archiver. this is because you are anyway trusting
the package to install files anywhere in the filesystem.
this serves rather as a sanity to check against errors in created
package.
|
|
the allows update-kernel script to work on tmpfs install before
cache is configured.

fetch_maperror() translates error codes returned by libfetch to our error
codes. Handle those in apk_error_str(), returning error messages which
advise the user of the most likely fix.
A custom error code, EAPKSTALEINDEX, has been added for cases where
retrieving a package fails due to a HTTP error 404 or similar.
[TimoT: add also EAPKBADURL, as well as organize a bit better where the
EAPKSTALEINDEX is generated]

According to the C standards, uint32_t is defined in stdint.h.
Presumably apk is usually built against C libraries where
stdint.h is indirectly included through another header file,
but this isn't the case with the version of glibc which I am using.

there's no nice syscall to manipulate xattrs with atfd and
or open the symlink without dereferencing it (and having fd
that we can do xattrs with)
|
|
user xattrs on tmpfs are not supported no non-grsec kernels,
and many times root fs is mounted without user_xattr. Thus
to allow things to go smoothly on non-grsec kernels xattr
unsupported errors are now hidden.
xattrs can be fixed still now with "apk fix --xattrs"

use ERR_PTR mechanism, and handle it at all places.
|
|
on arm char is by default unsigned, so this caused crashes
as the ERR_PTR mechanism did not work as expected with unsigned
types. extend the array type to be signed short explicitly.
