From signal man page :
"The behavior of signal() varies across Unix versions, and has also varied
historically across different versions of Linux. Avoid its use: use
sigaction(2) instead. See Portability below."
The code was taken from there :

This function was used in two different ways :
- as a signal handler : the argument was the signal number
- called manually for freeing the resources : the argument was the return
value
So the first part is now handler(int), and the second cleanup(int).
Ref: http://www.archlinux.org/pipermail/pacman-dev/2008-March/011388.html
Remaining problems :
- the return values are messy. for example, 2 can mean both that it was
interrupted (SIGINT == 2), or that --help or -V was used (returned by
parseargs).
- apparently signal is not portable and sigaction should be used instead

Due to the addition of the Chinese translation, our column widths were all
messed up as mentioned in the download progress commit fixing this same
problem there. This is a port of the code and ideas from that fix to the
installation progress bars. Once again, a handful of examples were tested to
ensure we work in all locales and with varying byte and char widths.

Now that we have a Chinese translation, all of the problems with new
character sets crop up. Assumptions were made in the past that all
characters occupied one column, which is not true with a Chinese character
set. In addition, the download code even failed on such things as 'ö', which
is two bytes wide but only 1 column.
This code will need to also be ported to the add/remove/upgrade/conflicts
progress printouts.
Note that the tests below try to incorporate a number of things:
1. download filenames too long to fit
2. download filenames cut off in the middle of a multibyte sequence
3. download filenames incorporating multicolumn chars
4. download filenames incorporating multibyte, single-column chars
5. 'plain' download filenames that have always worked

This fixes FS#6437. Dan already explained the problem in that bug report.
Instead of letting printf deal with the length of utf8 strings, we can
handle it more explicitly in the case of conflict progress bar, just like we
do for add/remove progress bars. We compute the remaining space left for
displaying the pkgname in case of add/remove, and an empty string in case of
conflict.

If we allow _parseconfig to continue processing when section is not defined,
then we have the potential to segfault during strcmp calls. This is no good.
For some reason, we had existing logic that tested this case but only if it
was processing and 'Include' directive. Expand the check to check for a NULL
section in all cases, and print an error message if this is the case.

I also changed it for fixing FS#8763 :
if there is exactly one provider, pacman will pull it and print a warning.
if there are several providers, pacman will list them and fail. It's up to
the user to pick one. Add sync501 pactest to reflect that.
It wasn't even implemented correctly, and it really doesn't have a use if
packagers just do their job correctly anyway for a distro. Let's not try to
solve a problem with the wrong solution now.

Thanks to Allan for inspiring all this work on what was one little TODO item
in the codebase. :)
Change changelog handling so we can now dump a changelog from both installed
packages and package files (fixes FS#7371). We do this by moving all of the
machinery to the backend where it should have been in the first place.
The changelog reading is now done through a open/read/close interface
similar to the fopen/fread/fclose functions (can you guess how it is done?).
It is buffered by the frontend, so programs using the library can read as
much or as little as they want at a time.
Unfortunately, I could not implement a changelog_feof function due to some
shortcomings of libarchive. However, I left the stub code in there,
commented out, in case it becomes possible later or anyone wants to take a
stab at it.

This feature (introduced by b118ce55bd as a
part of -Sc) could actually be helpful in the 3.0 -> 3.1 transition, because
all sync dbs will be left in /var/lib/pacman/, while the updated ones will
go to /var/lib/pacman/sync/.
So it'll now clean everything in /var/lib/pacman/, and only the unused
databases in /var/lib/pacman/sync/ (with the exception of local/ and sync/
in both cases).
Note: This feature is undocumented. I wonder if moving it to another option,
something like -S --dbclean, wouldn't help for documenting it.

When a DB is "registered" in libalpm, it goes and tries to create paths and
other BS which is stupid, but a pain in the butt to fix. For now, work

I made pacman path handling a bit odd with my rootdir changes a while back
in order to increase flexability. However, it had a bit of a drawback in
that dbpath/logfile/etc. would not default to being under the rootdir if
that was the only parameter you specified in the config file or on the
command line. (Note: logfile handling was always broken due to the explicit
logfile line required in config files)
Pacman now works as follows:
if a rootdir is specified but not dbpath or logfile:
attempt to place the logfile and dbpath in their default locations under
root
if an explicit dbpath/logfile is specified:
interpret these as absolute paths, regardless of the rootdir setting
if nothing is specified:
fall back to configured defaults

During a pacman operation such as a group install, pacman can ask several
questions such as "local version is up to date. Upgrade anyway?". They are
usually all answered either by yes or by no:
* yes when you want to reinstall all the targets.
* no when you only want to install the missing ones (either because you are
installing a group, or because you are copying a pacman -S line from wiki or
whatever).
So instead of asking this question for each target, it is now now configured
with a flag. Yes will be the default -S behavior, No will be achieved with
the --needed flag.
