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.

4e60b9646d fetch_url: look for files in cache before downloading
We lost this logic somewhere between the libfetch and libcurl

7f51ba99ae Fix segfaults on opening invalid archive files
"invalid" in this case simply means files that may or may not be
archives. Discovered via a `pacman -Sc` operation with delta files in
the package cache directory, but can be triggered if any file is passed
to `pacman -Ql` that isn't an archive, for instance, or if the sync
database file is not an archive.

Fix it up so we are more careful about calling archive_read_finish()
only on archives that are valid and have not already been closed, and
teach our archive open function to set the returned archive to NULL if
we aren't going to be returning something valid anyway.

d59324c8ff Use 32-bit wide integer type in PolarSSL code
A look at what this does on 64 bit systems since we were using the
unnecessarily large 'unsigned long' type before even though it was 64
bits wide:

$ ~/bin/bloat-o-meter libalpm.so.old lib/libalpm/.libs/libalpm.so
add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-10412 (-10412)
function                                     old     new   delta
md5_finish                                   370     356     -14
sha2_finish                                  547     531     -16
md5_process                                 3762    2643   -1119
sha2_process                               20356   11093   -9263

The code size is nearly halved in the sha2 case (44% smaller code size),
and md5 gets a nice size reduction (27% smaller) as well.

We also move base64 code to <stdint.h> types as well; we can use
'uint32_t' rather than 'unsigned long' for at least two variables in the
decode function. This doesn't net the same size benefit as the hash code
case, but it is more proper.

def9e45aff Search for PGP subkeys in a keyserver-acceptable way
PGP keyservers are pieces of sh** when it comes to searching for
subkeys, and only allow it if you submit an 8-character fingerprint
rather than the recommended and less chance of collision 16-character
fingerprint.

Add a second remote lookup for the 8-character version of a key ID if we
don't find anything the first time we look up the key. This fixes
FS#27612 and the deficiency has been sent upstream to the GnuPG users
mailing list as well.

0b9cd9448c pkghash improvements/modifications
This patch changes a variety of small things related to our pkghash
implementation with an eye toward performance, especially on native
32-bit systems.

* Use `unsigned int` rather than `size_t` for hash sizes. We already
  return ERANGE for any attempted creation of a hash greater than 1
  million elements, so unsigned int is more than large enough for our
  purposes. Switching to this type allows 32 bit systems to do native
  math without helper functions from libgcc.
* _alpm_pkghash_create() now internally adds extra padding for
  additional array elements, rather than that being the responsibility of
  the caller.
* #define values are moved into static const values in pkghash.c; a new
  `stride` value is also extracted (but remains set at 1).
* Division and modulus operators are removed from the normal find and
  add paths if possible. We store the upper limit of the number of
  elements in the hash so we no longer need to calculate this every
  element addition. When doing wraparound position calculations, we only
  apply the modulus operator if the value is greater than the number of
  buckets.

819c28bf8c Only compile delta regex once
This reduces the number of regcomp() calls when parsing delta entries in
the database from once per entry to once for the entire context handle
by storing the compiled regex data on the handle itself. Just as we do
with the cURL handle, we initialize it the first time it is needed and
free it when releasing the handle.

A few other small tweaks to the parsing function also take place,
including using the stack to store the transient and short file size
string while parsing it.

When parsing a sync database with 1378 delta entries, this reduces the
time of a `pacman -Sl deltas` operation by 50% from 0.22s to 0.12s.

39cb865e71 Simplify hash function to a single multiplication
More than likely the compiler will do the three operation breakdown we
had here before (2 shifts + subtraction), but let the compiler do the
optimizations and make the actual operation more obvious. This actually
slightly shrinks the function binary size, likely due to instruction
reordering or something.

6b29374a60 Rework package removal code
Extract the actual unlinking of files into a new method, which
eliminates a goto used for flow control. Also fix up a few small issues
in the code:

* Unnecessary (unsigned long) cast, use '%zd' instead
* Total up errors returned from unlink_file calls and return to caller
* Be consistent with scriptlets- we run pre_remove on dbonly, so we
  should also run post_remove. Both can be disabled by way of the
  --noscriptlet argument.
* Don't pass an invalid pointer to oldpkg to the event callbacks;
  instead call the callback before we free the object.

several paths did not have any messages at all before.

In addition, we now pick an ideal block size for the archive read based
off the larger value of our default buffer size or the st.st_blksize
field. For a filesystem such as NFS, this is often much larger than the
default 8192- values such as 32768 and 131072 are common.

6df558177f Convert package and database archive reads to use file descriptors
This gives us a bit more control and over the archive reading process,
and a bit less is done behind the scenes. It also allows us to use
fstat() in preference to stat(), which should avoid some potential race
conditions.

Some reorganization is necessary to move the stat calls after the open()
calls. Error handling and cleanup in general is also improved, as we had
several potential memory and file handle leaks before in some error
paths.

8a9ce12a27 Fix issues with replacing unowned symlinks
There aretwo seperate issues in the same block of file conflict
checking code here:
1) If realpath errored, such as when a symlink was broken, we would call
   'continue' rather than simply exit this particular method of
   resolution. This was likely just a copy-paste mistake as the previous
   resolving steps all use loops where continue makes sense. Refactor
   the check so we only proceed if realpath is successful, and continue
   with the rest of the checks either way.
2) The real problem this code was trying to solve was canonicalizing
   path component (e.g., directory) symlinks. The final component, if
   not a directory, should not be handled at all in this loop. Add a
   !S_ISLNK() condition to the loop so we only call this for real files.

There are few other small cleanups to the debug messages that I made
while debugging this problem- we don't need to keep printing the file
name, and ensure every block that sets resolved_conflict to true prints
a debug message so we know how it was resolved.

This fixes the expected failures from symlink010.py and symlink011.py,
while still ensuring the fix for fileconflict007.py works.

7a6b01d46c Don't realloc a 0-length files array when loading packages
There is some pecular behavior going on here when a package is loaded
that has no files, as is very common in our test suite. When we enter
the realloc/sort code, a package without files will call the following:

    files = realloc(NULL, 0);

One would assume this is a no-op, returning a NULL pointer, but that is
not the case and valgrind later reports we are leaking memory. Fix the
whole thing by skipping the reallocation and sort steps if the pointer
is NULL, as we have nothing to do.

Note that the package still gets marked as 'files loaded', becuase
although there were none, we tried and were successful.

Next, use archive_entry_mode() rather than archive_entry_stat() as we
only use the mode portion of the stat struct and the call is much
cheaper. Also delay it until it is necessary.

ae25167bcd Large performance improvement for check for owned directories
We can take a large shortcut here that saves us a lot of time,
especially when upgrading packages with lots of directories. Obviously
iterating the full file list of every single package to determine if
this directory was present in any other package can take quite some time
on a system with many packages installed. We don't need to remove a
directory at all if we are upgrading a package and the version we are
moving to still had the directory.

Also make a small optimization on the package comparsion- we really only
care about equality here, not the result of the compare, so we can
shortcut using our name_hash.

What kind of benefit does this give us? Oh, only a reduction from 295.7
million to 1.4 million strcmp() calls (99.5% fewer) during a
`pacman -S linux libreoffice-common` operation.

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

ea3c47825e Revert "libalpm: compare pkgname with strcoll"
This commit was made with the intent of displaying "correctly" sorted
package lists to users. Here are some reasons I think this is incorrect:

* It is done in the wrong place. If a frontend application wants to show
  a different order of packages dependent on locale, it should do that
  on its own.
* Even if one wants a locale-specific order, almost all package names
  are all ASCII and language agnostic, so this different comparison
  makes little sense and may serve only to confuse people.
* _alpm_pkg_cmp was unlike any other comparator function. None of the
  rest had any dependency on anything but the content of the structs
  being compared (e.g., they only used strcmp() or other basic
  comparison operators).

In the sync download code, we added an early check in 6731d0a940 for
sync download server existence so we wouldn't show the same error over
and over for each file to be downloaded. Move this check into the
download block so we only run it if there are actually files that need
to be downloaded for this repository.

When we switched to a file object and not just a simple string, we missed an

765178c5ba Implement PGP key search and import
Add two new static methods, key_search() and key_import(), to our
growing list of signing code.

If we come across a key we do not have, attempt to look it up remotely
and ask the user if they wish to import said key. If they do, flag the
validation process as a potential 'retry', meaning it might succeed the
next time it is ran.

These depend on you having a 'keyserver hkp://foo.example.com' line in
your gpg.conf file in your gnupg home directory to function.

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.

This takes the libraries hidden default out of the equation: hidden in
the sense that we can't even find out what it is until we create a
handle. This is a chicken-and-egg problem where we have probably already
parsed the config, so it is hard to get the bitmask value right.

Move it to the frontend so the caller can do whatever the heck they
want. This also exposes a shortcoming where the frontend doesn't know if
the library even supports signatures, so we should probably add a
alpm_capabilities() method which exposes things like HAS_DOWNLOADER,
HAS_SIGNATURES, etc.

ec790ced7c signing: add a process and retry loop for database signatures
In reality, there is no retrying that happens as of now because we don't
have any import or changing of the keyring going on, but the code is set
up so we can drop this in our new _alpm_process_siglist() function. Wire
up the basics to the sync database validation code, so we see something
like the following:

    $ pacman -Ss unknowntrust
    error: core: signature from "Dan McGee <dpmcgee@gmail.com>" is unknown trust
    error: core: signature from "Dan McGee <dpmcgee@gmail.com>" is unknown trust
    error: database 'core' is not valid (invalid or corrupted database (PGP signature))

    $ pacman -Ss missingsig
    error: core: missing required signature

    error: database 'core' is not valid (invalid or corrupted database (PGP signature))

8ffa2b24a5 Use more correct integer types in diskspace checks
This adjusts type usage to match POSIX provided types from
<sys/types.h> rather than assuming everything will fit in a long or

appropriate. These are affected the same way off_t is on 32 bit
platforms, where the types are extende to 64 bits if large file support
is enabled.

Because most numbers here are block counts, this isn't
near as pressing as using a 32-bit variable for file sizes where
anything over 2GiB can burn you; we likely can support files at least
512 but mainly 4096 times larger.

400942fedf avoid blowing out the filecache list when using tmpdir
_alpm_filecache_setup() destroys the list of cachedirs when it finds no
writeable directories in the config. This put us in an awkward situation
where _alpm_filecache_find() would locate a downloaded file in a r/o
cachedir, but then fail to install it after _alpm_filecache_setup() is
called (with a NULL argument). Change this behavior to merely prepend
the temporary directory to the list of available cachedirs.

Dan exposed it in e07547ee4e, as now a package can be found in a
directory we may not be able to actually store packages in.

is a signed type, but in our usages, we never parse or have a need for
negative values, so the function will return -1 on error.

our strcmp() conditional checks as normal.

Some local numbers follow to show the effects of this patch:

Sync `-Ss foobarbaz`:
71,709 blank lines skipped early
~1,505,889 strcmp() calls avoided (21 per line)
~15% speed improvement (.210 --> .179 sec)

Local `-Qs foobarbaz`:
6,823 blank lines skipped early
115,991 strcmp() calls avoided (17 per line)
~6% speed improvement (.080 -> .071 sec)

de43d00db0 Refactor signature result return format
I was trying to take a shortcut and not introduce a wrapper struct for
the signature results, so packed it all into alpm_sigresult_t in the
first iteration. However, this is painful when one wants to add new
fields or only return information regarding a single signature.

Refactor the type into a few components which are exposed to the end
user, and will allow a lot more future flexibility. This also exposes
more information regarding the key to the frontend than was previously
available.

The "private" void *data pointer is used by the library to store the
actual key object returned by gpgme; it is typed this way so the
frontend has no expectations of what is there, and so we don't have any
hard gpgme requirement in our public API.

30d978a966 vercmp: ensure 2.0a and 2.0.a do not compare equal
We had this interesting set of facts conundrum, according to vercmp
return values:
    2.0a <  2.0
    2.0  <  2.0.a
    2.0a == 2.0.a

This introduces a code change that ensures '2.0a < 2.0.a' as would be
expected by the first two comparisons. Unfortunately this stays us a bit
further from upstream RPM code, but those are the breaks (in RPM, the
versions involving 'a' do in fact compare the same, but they are both
greater than the bare '2.0').

e07547ee4e Rework finding a writable cache directory
This is a refactor and refresh of the code used to find where we should
download packages.

* Incorporate suggestions from FS#25435 to use TMPDIR from the
  environment if set, otherwise fall back to /tmp as before.
* Make the writability tests a bit more in depth. We now do a three part
  check consisting of:
  - S_ISDIR(): is this even a directory
  - access(W_OK): is this directory writable by the current user.
    Unfortunately for root, this almost always returns that it is, but
    in the case of a RO mount or NFS share inaccessible to root, this
    check will exclude the directory.
  - mode & (any write bit): is there a writable bit set on this
    directory. This makes it possible to enforce a read-only cache
    directory by setting permissions to 0555, for example.

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.

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.

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.
