In case we have a mirror failure, unlink_on_fail would remain set,

Dan McGee b488f229d2 ALPM API adjustments for sanity and consistency
This makes several small adjustments to our exposed method names, and in
one case, parameters. The justification here is to make methods less odd
in their naming convention. If a method takes an alpm_db_t argument, the
method should be named 'alpm_db_*', but perhaps more importantly, if it
doesn't take a database as the first parameter, it should not.

Summary of changes:

    alpm_db_register_sync   -> alpm_register_syncdb
    alpm_db_unregister_all  -> alpm_unregister_all_syncdbs
    alpm_option_get_localdb -> aplpm_get_localdb
    alpm_option_get_syncdbs -> aplpm_get_syncdbs
    alpm_db_readgroup       -> alpm_db_get_group
    alpm_db_set_pkgreason   -> alpm_pkg_set_reason

All methods keep the same argument list except for alpm_pkg_set_reason;
there we drop the 'handle' argument as it can be retrieved from the
passed in package object.

Dan McGee b3612e9cc1 Allow UseDelta option to specify a delta ratio
Rework the frontend and backend to allow passing a ratio value in for
UseDelta rather than having a hardcoded #define-d 0.7 value always used.
This is useful for those with fast connections, who would likely benefit
from tuning this ratio to lower values; it is also useful for general
testing purposes.

The libalpm API changes for this, but we do support the old config file
format with a no-value 'UseDelta' option; in this case we simply use the
old default of 0.7.

We clamp the ratio values to a sane range between 0.0 and 2.0, allowing
ratios above 1.0 for testing purposes.

We opt for -imacros over -include as its more portable, and the
added constraint by -imacros doesn't bother us for config.h.

This also touches the HACKING file to remove the explicit mention of
config.h as part of the includes.

When doing a bare -U operation on a local package that doesn't pull in

database files. This makes the check conditional on no sync targets
found in the target list. This is not the prettiest code here so we have
a bit of hackish behavior required to straighten both the behavior and
the nonsensical error message out.

Dan McGee e0acf2f144 Refactor download payload reset and free
This was done to squash a memory leak in the sync database download
code. When we downloaded a database and then reused the payload struct,
we could find ourselves calling get_fullpath() for the signatures and
overwriting non-freed values we had left over from the database
download.

Refactor the payload_free function into a payload_reset function that we
can call that does NOT free the payload itself, so we can reuse payload
structs. This also allows us to move the payload to the stack in some
call paths, relieving us of the need to alloc space.

Dan McGee 40a264478e Track unresolvable transaction packages
Rather than free them right away, keep the list on the transaction as
we already do with add and remove lists. This is necessary because we
may be manipulating pointers the frontend needs to refer to packages,
and we are breaking our contract as stated in the alpm_add_pkg()
documentation of only freeing packages at the end of a transaction.

This fixes an issue found when refactoring the package list display
code.

Dan McGee f66f9f11cd Fix memory leak in download payload->remote_name
In the sync code, we explicitly allocated a string for this field, while
in the dload code itself it was filled in with a pointer to another
string. This led to a memory leak in the sync download case.

Make remote_name non-const and always explicitly allocate it. This patch
ensures this as well as uses malloc + snprintf (rather than calloc) in
several codepaths, and eliminates the only use of PATH_MAX in the
download code.

Dan McGee 4849a4596d Add _alpm_process_siglist() logic to failed package validation
This moves the result processing out of the validation check loop itself
and into a new loop. Errors will be presented to the user one-by-one
after we fully complete the validation loop, so they no longer overlap
the progress bar.

Unlike the database validation, we may have several errors to process in
sequence here, so we use a function-scoped struct to track all the
necessary information between seeing an error and asking the user about
it.

The older prompt_to_delete() callback logic is still kept, but only for
checksum failures. It is debatable whether we should do this at all or
just delegate said actions to the user.

Dan McGee 01f5c9e79a validate_deltas: split verify/check errors loops
This allows us to do all delta verification up front, followed by
whatever needs to be done with any found errors. In this case, we call

Add back the missing EVENT(ALPM_EVENT_DELTA_INTEGRITY_DONE) that
accidentally got removed in commit 062c391919.

Remove use of *data; we never even look at the stuff in this array for
the error code we were returning and this would be much better handled
by one callback per error anyway, or at least some strongly typed return
values.

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.

Dave Reisner b008193c12 dload: zero out pm_errno in curl_download_internal
This reverts some hacky behavior from 5fc3ec and resets the handle's
pm_errno where it should be reset -- prior to each download. This
prevents a transaction with a download from being aborted when a package
is successfully grabbed from a secondary server.

Dave Reisner 5fc3ecf7f8 lib/sync: ignore download errors for as long as possible
Previously, the behavior was such that if a sync operation required
packages from multiple repos, a download error in the first repo would
cause a hard repo, ignoring the remainder of the repositories. Change
this behavior so that we do a better job of fetching as many packages as
possible before aborting the transaction.

There's a little bit of refactoring mixed in here to get rid of some
useless variables. Since we now depend heavily on the value of
handle->pm_errno being accurate the determine the function's return
value, we clear it when the transaction state is set.

Fixes FS#25532.

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.

Dan McGee 9d09c9fdf7 Attempt to fix up some of the brokenness around failed package loads
This is a bit of a mess, due to the fact that we have a progress meter
running. It is also ironic that we are in the midst of a method named
"commit" when we haven't done a damn thing yet, and can still fail hard
if either a checksum or signature is invalid or unrecognized.

Adapt the former test_md5sum method to be invoked for any of the various
failure types, which at least gives the user some indication of what
packages are failing. A second patch will be needed to actually show
worthwhile error codes, but this is going to involve modifying the
actual data passed with the callback.

Dave Reisner 6dc71926f9 lib/dload: prevent large file attacks
This means creating a new struct which can pass more descriptive data
from the back end sync functions to the downloader. In particular, we're
interested in the download size read from the sync DB. When the remote
server reports a size larger than this (via a content-length header),
abort the transfer.

In cases where the size is unknown, we set a hard upper limit of:

* 25MiB for a sync DB
* 16KiB for a signature

For reference, 25MiB is more than twice the size of all of the current
binary repos (with files) combined, and 16KiB is a truly gargantuan
signature.

Dave Reisner 6c9b82e72a dload: handle irregular URLs
URLs might end with a slash and follow redirects, or could be a
generated by a script such as /getpkg.php?id=12345. In both cases, we
may have a better filename that we can write to, taken from either
content-disposition header, or the effective URL.

Specific to the first case, we write to a temporary file of the format
'alpmtmp.XXXXXX', where XXXXXX is randomized by mkstemp(3). Since this
is a randomly generated file, we cannot support resuming and the file is
unlinked in the event of an interrupt.

We also run into the possibility of changing out the filename from under
alpm on a -U operation, so callers of _alpm_download can optionally pass
a pointer to a *char to be filled in by curl_download_internal with the
actual filename we wrote to. Any sync operation will pass a NULL pointer
here, as we rely on specific names for packages from a mirror.

Fixes FS#22645.

Dan McGee c748eadc80 Allow invalid sync DBs to be returned by the library
They are placeholders, but important for things like trying to re-sync a
database missing a signature. By using the alpm_db_validity() method at
the right time, a client can take the appropriate action with these
invalid databases as necessary.

In pacman's case, we disallow just about anything that involves looking
at a sync database outside of an '-Sy' operation (although we do check
the validity immediately after). A few operations are still permitted-
'-Q' ops that don't touch sync databases as well as '-R'.

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 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.
