Some systems, like FreeBSD might define both statfs

uses a statfs struct, the current ifdefs would select the wrong

We didn't do this sanity check before trying to open an archive. If
the alpm dbpath wasn't set, the sync database dbpath would be NULL,
causing us to hang indefinitely in archive_read_open_filename() rather
than erroring out.
We already have a corresponding check in local_db_populate().
The following program will test this case, and hangs before this patch
without the call to set_dbpath:
int main(int argc, char *argv[]) {
alpm_initialize();
// alpm_option_set_dbpath("/var/lib/pacman/");
pmdb_t *core = alpm_db_register_sync("core");
pmpkg_t *pkg = alpm_db_get_pkg(core, "pacman");
return 0;

This addresses FS#23424. The -dd backend code was introduced in commit
b6ec9019d7, and unfortunately the munged depend used for comparison did
not carry through to the eventual display of this version. To fix this,
we undo some of the depcmp_tolerant() business introduced, and instead
make a new pmdepend_t object if necessary when the no dependency version
flag is set. This results in the correct depend being copied to the
missing depend passed onto the frontend.

This is a rather serious data corruption issue that luckily manifested
itself today in a noticable way. A package in testing had replaces

Adding the CURLcode is necessary in order to return an error string from
pm_error. Unlike libfetch, curl returns numerical error numbers and does
not maintain a staticly allocated string with the last error generated.
Adding the curl object itself to the handle is advantageous (and
encouraged by curl_easy_perform(3)) because the handle is reusable for
successive operations. This cuts back on overhead when downloading
multiple files in a single transaction.
