Dan McGee 3796164848 Access db->pkgcache directly in db_free_pkgcache()
We shouldn't be going through the accessor that does a bunch of
unnecessary legwork, including potentially loading the pkgcache right
before we free it.

Dan McGee 86d9fcbfff Remove const specifier from changelog_read() void parameter
This shouldn't really be declared with const, and causes a compile error
when -Wcast-qual is used. Remove the const specifier from the function
specification and all implementations.

Also fix one other trivial -Wcast-qual warning in _alpm_db_cmp().

Dan McGee 6d544984f2 Be more robust when copying package data
This changes the signature of _alpm_pkg_dup() to return an integer error
code and provide the new package in a passed pointer argument. All
callers are now more robust with checking the return value of this
function to ensure a fatal error did not occur.

We allow load failures to proceed as otherwise we have a chicken and egg
problem- if a 'desc' local database entry is missing, the best way of
restoring said file is `pacman -Sf --dbonly packagename`. This patch
fixes a segfault that was occurring in this case.

Fixes the segfault reported in FS#25667.

Dan McGee c4bd476ad1 Remove use of no-op accessor functions in library
The functions alpm_db_get_name(), alpm_pkg_get_name(), and
alpm_pkg_get_version() are not necessary at all, so remove the calling
and indirection when used in the backend, which makes things slightly
more efficient and reduces code size.

Dan McGee c885a953eb Enhance and utilize database status flags
* Move is_local standalone field to status enum
* Create VALID/INVALID flag pair
* Create EXISTS/MISSING flag pair

With these additional fields, we can be more intelligent with database
loading and messages to the user. We now only warn once if a sync
database does not exist and do not continue to try to load it once we
have marked it as missing.

The reason for the flags existing in pairs is so the unknown case can be
represented. There should never be a time when both flags in the same
group are true, but if they are both false, it represents the unknown
case. Care is taken to always manipulate both flags at the same time.

Dan McGee 11f4a7a48e Only check necessary signatures and checksums
The precedence goes as follows: signature > sha256sum > md5sum

Add some logic and helper methods to check what we have available when
loading a package, and then only check what is necessary to verify the
package. This should speed up sync database verifies as we no longer
will be doing both a checksum and a signature validation.

Dan McGee a628feee46 Parse conflicts/provides/replaces at database load time
We did this with depends way back in commit c244cfecf6 in 2007. We
can do it with these fields as well.

Of note is the inclusion of provides even though only '=' is supported-
we'll parse other things, but no guarantees are given as to behavior,
which is more or less similar to before since we only looked for the
equals sign.

Also of note is the non-inclusion of optdepends; this will likely be
resolved down the road.

The biggest benefactors of this change will be the resolving code that
formerly had to parse and reparse several of these fields; it only
happens once now at load time. This does lead to the disadvantage that
we will now always be parsing this information up front even if we never
need it in the split form, but as these are uncommon fields and our
parser is quite efficient it shouldn't be a big concern.

This can only ever operate on the local database, and a local package at

Dan McGee 7af0ab1cde signing: move to new signing verification and return scheme
This gives us more granularity than the former Never/Optional/Always
trifecta. The frontend still uses these values temporarily but that will
be changed in a future patch.

* Use 'siglevel' consistenly in method names, 'level' as variable name
* The level becomes an enum bitmask value for flexibility
* Signature check methods now return a array of status codes rather than
  a simple integer success/failure value. This allows callers to
  determine whether things such as an unknown signature are valid.
* Specific signature error codes mostly disappear in favor of the above
  returned status code; pm_errno is now set only to PKG_INVALID_SIG or
  DB_INVALID_SIG as appropriate.

Dan McGee 79e98316ea Add a 'valid' flag to the database object
Start by converting all of our flags to a 'status' bitmask (pkgcache
status, grpcache status). Add a new 'valid' flag as well. This will let
us keep track if the database itself has been marked valid in whatever
fashion.

For local databases at the moment we ensure there are no depends files;
for sync databases we ensure the PGP signature is valid if
required/requested. The loading of the pkgcache is prohibited if the
database is invalid.

Dan McGee db3b86e7f3 Do database signature checking at load time
This is the ideal place to do it as all clients should be checking the
return value and ensuring there are no errors. This is similar to
pkg_load().

We also add an additional step of validation after we download a new
database; a subsequent '-y' operation can potentially invalidate the
original check at registration time.

Note that this implementation is still a bit naive; if a signature is
invalid it is currently impossible to refresh and re-download the file
without manually deleting it first. Similarly, if one downloads a
database and the check fails, the database object is still there and can
be used. These shortcomings will be addressed in a future commit.

Dan McGee ee015f086f Ensure handle is valid and pm_errno is reset when calling into API
We didn't do due diligence before and ensure prior pm_errno values
weren't influencing what happened in further ALPM calls. I observed one
case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that
flag persisting the entire time we were calling library code.

Add a new CHECK_HANDLE() macro that does two things: 1) ensures the
handle variable passed to it is non-NULL and 2) clears any existing
pm_errno flag set on the handle. This macro can replace many places we
used the ASSERT(handle != NULL, ...) pattern before.

Several other other places only need a simple 'set to zero' of the
pm_errno field.

Dan McGee fb4b422fc4 New signatures for alpm initialize and release
These new method signatures return and take handle objects to operate on
so we can move away from the idea of one global handle in the API. There
is also another important change and that deals with the setting of root

setter methods. This allows the library to operate more safely knowing
that paths won't change underneath it.
