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.

in the case where gettext is unavailable. This prevents a number of

On operating systems we support, the behavior is always such that the
kernel will do the right thing as far as invalidating the file
descriptor, regardless of the eventual return value. Therefore,
potentially looping and calling close multiple times is wrong.
At best, we call close again on an invalid FD and throw a spurious EBADF
error. At worst, we might close an FD which doesn't belong to us when a
multi-threaded application opens its own file descriptor between
iterations of the loop.

There is duplicated code in the util.c files in the libalpm and pacman
source code. Split this into a separate file so that it can be shared
via a symlink. This prevents code divergence between the two code bases.
Also, move mbasename and mdirname from pacman/util.c into util-common.c
in preparation for the following patch that uses them to add an extension

This path is rarely (read: never) taken in any normal run of the code,
so injecting the fprintf() call everywhere with the macro is a bit
overkill. Instead, add a lightweight _alpm_alloc_fail() function that
gets called instead.
This does have a reasonable effect on the size of the generated code;
most places using the macros provided by util.c have their code size
reduced.

This moves the code for removal of local database entries right into

Ensures that config.h is always ordered correctly (first) in the
includes. Also means that new source files get this for free without
having to remember to add it.
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.

This moves the common setup code of about 5 different callers into one
method. Error messages will now be common and shared in all places;
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.

This takes the place of three previously used constants:
ARCHIVE_DEFAULT_BYTES_PER_BLOCK, BUFFER_SIZE, and CPBUFSIZE.
In libarchive 3.0, the first constant will be no more, so we can ensure
we are forward-compatible by removing our usage of it now. The rest are
unified for consistency.
By default, we will use the value of BUFSIZ provided by <stdio.h>, which
is 8192 on Linux. If that is undefined, a default value is provided.

This will always be a 64-bit signed integer rather than the variable length
time_t type. Dates beyond 2038 should be fully supported in the library; the
frontend still lags behind because 32-bit platforms provide no localtime64()

We were using atol(), which on 32 bit, cannot handle values greater than
2GiB, which is fail.
Switch to a strtoull() wrapper function tailored toward parsing off_t
values. This allows parsing of very large positive integer values. off_t
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.

We don't write with extra or unknown whitespace, so there is little
reason for us to trim it when reading either. This also fixes the
hopefully never encountered "paths that start or end with spaces" issue,
for which two pactests have been added. The tests also contain other
evil characters that we have encountered before and handle just fine,
but it doesn't hurt to ensure we don't break such support in the future.

This addresses FS#25141. We shouldn't remove every empty directory we
come across during the removal process unless it is truly not known to
any other package. This will prevent removal of essential directories
such as '/var/lock/'.
This is accomplished by first checking the empty/non-empty status of a
directory, which was previously done implicitly by calling rmdir() and
ignoring errors. We do this to avoid the next (new) check in most cases,
which is to look at all local packages to see if the to-be-removed
directory is present in another packages' filelist. If we do not find it
anywhere, then we remove it, else we keep the file around.
The pactest has been updated to test more cases, as well as finding a
flaw in the original expected to fail case- we need separate DIR and
FILE based EXIST rules.

We can reorganize things a bit to not require reading a directory-only
entry first (or at all). This was noticed while working on some pactest
improvements, but should be a good step forward anyway.

data it parses.

This is an unfortunate chain of events. RET_ERR and RET_ERR_VOID will
eventually call CHECK_HANDLE, which resets the handle's pm_errno member.
Dan probably had a reason for doing this, so we merely switch the order
of operations in the RET_ERR macros to avoid stomping on our pm_errno.
Signed-off-by: Dave Reisner <d@falconindy.com>
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.
