Ivy Foster fa06951d90 Represent bitfields as ints, not enums
Many bitfield variables are declared to be enums, because they are
generated using bitwise operations on enums such. However, their
actual values aren't necessary members of their parent enum, so
declaring them 'int' is more accurate.

Andrew Gregory a724235b61 make alpm_unlock and trans_interrupt async safe
RET_ERR calls _alpm_log which includes calls that are not safe for use
in asynchronous signal handlers (see signal(7)).  Replace it in
functions called from our signal handlers with a new macro
RET_ERR_ASYNC_SAFE which is identical except that it lacks the call to
_alpm_log.

Andrew Gregory c792262b13 wrap fgets to retry on EINTR
The read() underlying fgets() can be interrupted by a signal handler
causing fgets() to return NULL.  Before we started handling SIGWINCH,
the odds of interrupting a read were low and typically resulted in
termination anyway.  Replace all fgets calls with a wrapper that retries
in EINTR.

Allan McRae 3ba5391839 Allow specifying shell for running scriptlets
Some distributions insist on using bash specific commands in their
install scripts under the assumption that "sh" is a symlink to bash.
This can causes issues if (e.g.) their users what to change sh to
point at another shell, such as dash, that does not support these
features. Add a configure option to explicitly set the shell being
used to run install scripts.

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

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 e1899cbc64 Be smarter about running ldconfig during removal transactions
1. Don't run it if something failed in package removal- this mirrors
what we already do in sync transactions.
2. Don't run it if we are invoking it for the replaces removal bit of a
sync transaction- it doesn't make sense to run ldconfig halfway through
a sync install; we should only run it once at the end.

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 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 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.
