From the fgets manpage:
fgets() reads in at most one less than size characters from stream and
stores them into the buffer pointed to by s. Reading stops after an EOF
or a newline. If a newline is read, it is stored into the buffer. A
'\0' is stored after the last character in the buffer.
This means there is no need at all to do 'size - 1' math. Remove all of that
and just use sizeof() for simplicity on the buffer we plan on reading into.

Sorry for this being such a huge patch, but I believe it is necessary for
quite a few reasons which I will attempt to explain herein. I've been
mulling this over for a while, but wasn't super happy with making the
download interface more complex. Instead, if we carefully order things in
the internal download code, we can actually make the interface simpler.
1. FS#15657 - This involves `name.db.tar.gz.part` files being left around the
filesystem, and then causing all sorts of issues when someone attempts to
rerun the operation they canceled. We need to ensure that if we resume a
download, we are resuming it on exactly the same file; if we cannot be
almost postive of that then we need to start over.
2. http://www.mail-archive.com/pacman-dev@archlinux.org/msg03536.html - Here
we have a lighttpd bug to ruin the day. If we send both a Range: header and
If-Modified-Since: header across the wire in a GET request, lighttpd doesn't
do what we want in several cases. If the file hadn't been modified, it
returns a '304 Not Modified' instead of a '206 Partial Content'. We need to
do a stat (e.g. HEAD in HTTP terms) operation here, and the proceed
accordingly based off the values we get back from it.
3. The mtime stuff was rather ugly, and relied on the called function to
write back to a passed in reference, which isn't the greatest. Instead, use
the power of the filesystem to contain this info. Every file downloaded
internally is now carefully timestamped with the remote file time. This
should allow the resume logic to work. In order to guarantee this, we need
to implement a signal handler that catches interrupts, notifies the running
code, and causes it to set the mtimes on the file. It then rethrows the
signal so the pacman signal handler (or any frontend) works as expected.
4. We did a lot of funky stuff in trying to track the DB last modified time.
It is a lot easier to just keep the downloaded DB file around and track the
time on that rather than in a funky dot file. It also kills a lot of code.
5. For GPG verification of the databases down the road, we are going to need
the DB file around for at least a short bit of time anyway, so this gets us
closer to that.

alpm_pkg_get_name() gives us little benefit in backend code besides a NULL
check on the package passed in; we could do that ourself if necessary. By
changing to direct references in the cases where we are sure we have a valid
package, we save a function call each time we need a package name. This
function can't be inlined because it is externally accessible.

With this patch, we no longer compute the individual repository DB paths

struct __pmtrans_t {
- pmtranstype_t type;
pmtransflag_t flags;
pmtransstate_t state;
- alpm_list_t *packages; /* list of (pmpkg_t *) */
+ alpm_list_t *add; /* list of (pmpkg_t *) */
+ alpm_list_t *remove; /* list of (pmpkg_t *) */
And then I have to modify all the code accordingly.
This patch utilizes the power of sync.c to fix FS#3492 and FS#5798.
Now an upgrade transaction is just a sync transaction internally (in alpm),
so all sync features are available with -U as well:
* conflict resolving
* sync dependencies from sync repos
* remove unresolvable targets
See http://www.archlinux.org/pipermail/pacman-dev/2009-June/008725.html
for the concept.
We use "mixed" target list, where PKG_FROM_FILE origin indicates local
package file, PKG_FROM_CACHE indicates sync package. The front-end can add
only one type of packages (depending on transaction type) atm, but if alpm
resolves dependencies for -U, we may get a real mixed trans->packages list.
_alpm_pkg_free_trans() was modified so that it can handle both target types
_alpm_add_prepare() was removed, we use _alpm_sync_prepare() instead
_alpm_add_commit() was renamed to _alpm_upgrade_targets()
sync.c (and deps.c) was modified slightly to handle mixed target lists,
the modifications are straightforward. There is one notable change here: We
don't create new upgrade trans in sync.c, we replace the pkgcache entries
with the loaded package files in the target list (this is a bit hackish) and
call _alpm_upgrade_targets(). This implies a TODO (pkg->origin_data.db is
not accessible anymore), but it doesn't hurt anything with pacman front-end,
so it will be fixed later (otherwise this patch would be huge).
I updated the documentation of -U and I added a new pactest, upgrade090.py,
to test the syncdeps feature of -U.

than stable" messages, nothing more). That's why I introduced -Suu, which
treats a sync package like an upgrade, iff the package version doesn't match
with the local one's.
I added a new pactest (sync104.py) to test this, and I updated the
documentation of -Su.

This happens for example if you install a new package, and one of its
backup config file is already on the file system.
If the local file was different, it was saved to .pacorig which is fine.
However if the local file and pkg file were the same, the pkg file
(temporarily extracted as .paccheck) was left on the system.

"Foo replaces bar" simply means that "foo is a new version of bar".
So this patch refactors the code to use this "rule".
_alpm_sync_sysupgrade now does the following for each local package [bar]
(pseudo-code):
for db in syncdbs {
if(db contains bar) {check if db/bar is an upgrade; break;}
replacers = find(bar replacers in db);
if(replacers!=NULL) {ask_user; break;}
}
Note:
1. Replacers are grouped per repo. If more than one package replace bar in
a repo, all of them are considered ("package set of bar replacers").
2. If repo1/foo1 and repo2/foo2 both replaces bar, only repo1/foo1 is
considered (if repo1 stands before repo2 in pacman.conf). FS#11737 is fixed.
3. It can happen that pacman doesn't consider any replacer, if it found a
literal "earlier", so sync132.py modified accordingly (btw, that situation
should not appear irl).
The new sysupgrade code doesn't use sync_newversion(), so I removed the
"local is newer than repo" message, which was annoying with -Qu and
SyncFirst.

behavior of IgnorePkg/IgnoreGroup to allow the user to remove unresolvable
packages from the transaction. The bug is that the target-list was no

explicitly requested one of those two packages in the sync, the other
package was still being pulled in.

pmsyncpkg_t data sructure was removed:
1. pmpkg_t.reason is used instead of pmsyncpkg_t.newreason. (The target
packages come from sync repos, so we can use this field without any
problems. Upgrade transaction also uses this field to store this info.)
2. pmsyncpkg_t.removes was moved to pmpkg_t.removes.
This step requires careful programming, because we don't duplicate packages
when we add them to trans->packages. So we modify sync pkgcache when we
add this transaction-only info to our package. Hence it is important to
free this list when we remove any package from the target list
(remove_unresolvable, remove_conflicts, trans_free), otherwise this could
confuse the new sync transactions (with non-pacman GUI).
Overall, our code became ~100 line shorter, and we can call our helper
functions directly on trans->packages in sync.c, we don't need to maintain
parallel package lists.

From now on _alpm_db_find_fileconflicts() works with upgrade and remove
target lists (like checkdeps), which makes it transaction independent
(we still need a trans param because of the progressbar). This is a small
step towards the universal transaction. So we call this function directly
from sync.c before commiting the remove transaction. This is much safer,
but we can get false fileconflict error alarms in some tricky cases
("symlinks puzzle" etc).
The patch on find_fileconflict looks complex, but it is mainly an
"indent-patch", the new code-part can be found after the
/* check remove list ... */ comment, and I modified something around the
"file has changed hand" case (see comment modifications in the code).
Unfortunately sync.c became more ugly, because we have to create 2 parallel
internal transactions: to avoid duplicated work, upgrade transaction is
used to load package data (filelists). This problem will disappear, when
we finally get rid of internal transactions.

This change was wrong, popen does require /bin/sh in a subchroot.
1) pacman -S lilo -r root

2) rm root/bin/sh ; pacman -S lilo -r root

error: scriptlet failed to execute correctly
Actually, we already get an explicit error here, when popen is run, so there
is no need to check for bin/sh explicitely.
Besides this check was problematic in some cases. For example, bash itself
has a scriptlet, but only post_install and post_upgrade, no pre_install and
pre_upgrade. However, since bash has a scriptlet, runscriptlet will also be
called before bash is installed. It won't do anything since the scriptlet
has no pre_install function. But if we keep the check, we will still get
"error : no /bin/sh".

* The child inherits copies of the parent's set of open file

file description (see open(2)) as the corresponding file descriptor in the
parent. This means that the two descriptors share open file status
flags, current file offset, and signal-driven I/O attributes (see the
description of F_SETOWN and F_SETSIG in fcntl(2)).

Your example unstable.db.tar.gz is not empty. It has
one entry in it, called "./". That entry is marked
as a directory. But, when you call archive_entry_set_mode(),
you are changing the file type! archive_read_extract()
then creates the file /var/unstable as you requested.
(archive_read_extract() will replace an empty directory
with a file.)
You should either set the mode value correctly:
323 if(S_ISREG(st->st_mode)) {
324 archive_entry_set_mode(entry, IFREG | 0644);
325 } else if(S_ISDIR(st->st_mode)) {
326 archive_entry_set_mode(entry, IFDIR | 0755);
327 }
Or use archive_entry_set_perm(), which does not change
the file type:
323 if(S_ISREG(st->st_mode)) {
324 archive_entry_set_perm(entry, 0644);

Clearly the old code was more elegant (NULL cache indicated "not loaded"),
but it had some drawbacks, so from now on we indicate the state of caches
explicitly.
Old drawbacks:
When we had an empty database (unstable), libalpm called db_populate after
every pkgcache access, because NULL pkgcache indicated "not loaded" state.
This is not a common case, but the same situation can happen with grpcache,
which is more problematic: If the user had a custom repo with no groups,
grpcache was always NULL. (grpcache is also loaded per database.) Thus
every get_grpcache call induced a load_grpcache operation, so the benefits
of grpcache was completely lost.

Before commit fc48dc31, file:/// urls forced the use of the internal
downloader (libdownload), because the default XferCommand, wget, does not
handle them. We tried to move away from forcing usage of libdownload, so
this commit implemented the handling of file:/// urls manually. However,
this implementation is way too basic. It does not handle the progress bar,
thus nothing at all appears in pacman's output when a file: repo is
synchronized, or when a file is downloaded from a sync repo. Also, it is not
able to detect when the repo is already up-to-date. When libdownload was
used, both were handled.
It seems better to just drop this implementation for now. All users who use
libdownload will get the much better file:// handling back. For the users of
XferCommand, it will be more problematic, but they have several options:
1) Switch to a downloader handling file:// (wget doesn't, but curl does for
example).
2) Drop the file:// repo, and set up light http or ftp servers instead.
Consider that going that way would make this repo available for the whole
local network, which can be useful.
3) Switch back to libdownload, which works perfectly for many users.

The pkg_dup function shouldn't call any alpm_pkg_get_ accessors because
this can fill the old package with all INFRQ_DESC fields for example, and
this won't necessarily be reproduced in the new package (for all the fields
that were copied before).

This vercmp issue has been a sticking point but this should resolve many of
the issues that have come up. Only a few minor code changes were necessary
to get the behavior we desired, and this version appears to beat any other
vercmp rendition on a few more cases added in this commit.
This commit passes all 58 vercmp tests currently out there. Other 'fixes'
still fail on a few tests, namely these ones:
test: ver1: 1.5.a ver2: 1.5 ret: -1 expected: 1

Commit 8240da6cb3 broke some alpm hierarchy
and introduced a new memleak (trans->packages was never freed in case of add
transaction, even if the transaction wasn't committed), so it is reverted
now.
We follow a different approach to reduce memory usage:
_alpm_db_add_pkgincache doesn't duplicate the whole package before adding
it to the cache, only the package name and version (INFRQ_BASE).
This method needs very small extra memory (compared to the reverted method),
and after transaction commit we use less memory than before (since the
big 'files' fields are not copied to cache), this is useful in GUIs.
Note: The old add_pkgincache was a bit broken, since pkg->origin wasn't
filled in correctly.

Now '-S provision' handling is done in the back-end.
In case of multiple providers, the first one is selected (behavior change:
deleted provision002.py). The old processing order was: literal, group,
provision; the new one: literal, provision, group. This is more rational,
but "pacman -S group" will be slower now. "pacman -S repo/provision" also
works. Provision was generalized to dependencies, so you can resolve deps by
hand: "pacman -S 'bash>2.0'" or "pacman -S 'core/bash>2.0'" etc. This can be
useful in makepkg dependency resolving. The changes were documented in
pacman manual.
alpm_find_pkg_satisfiers and _alpm_find_dep_satisfiers functions were
removed, since they are no longer needed.
I added some verbosity to "select provider instead of literal" and
"fallback to group".

I divided resolvedeps into 2 functions. The new _alpm_resolvedep function
will resolve one dependency, for example the 'foo>=1.0-1' dependency. It
can be useful in sync_addtarget refactoring.
The resolvedeps parameters were changed, to be coherent with recursedeps:
* the target-list is an alpm_list* instead of alpm_list**. This is OK,
because alpm_list_add == alpm_list_add_last
* syncpkg param was removed. list contains the to-be-installed packages,
resolvedeps will add the required dependencies into this list
* trans param was removed, it was used in QUESTION() only, which can be used
on the main (handle->trans) transaction only (because the front-end cannot
access our pseudo-transactions at all!).
The patch fixes some wrong dynamic pmdepmissing_t usage.
I did a behavior change (and sync1003.py was modified accordingly), which
needs some explanation: The old resolvedeps didn't elect packages from
'remove' list. I've dropped this because I don't want that 2nd excluding
list param. In fact, in real life, we ~never need this rule. Resolvedeps is
called before checkconflicts, so only -Su's %REPLACES% packages are sitting
in 'remove' list. This means, that we have the replacement packages in our
target list. Usually "foo replaces bar" means, that bar isn't in our repos
any more, so resolvedeps *cannot* elect it; but usually it won't try it at
all, because foo is in the target list, and it is expected to satisfy
'bar>=1.0-1'-like dependencies too. Since checkdeps and checkconflicts is
done after resolvedeps, this cannot cause any harm.

Some previous commits apparently broke the get_filename function for package
loaded with pkg_load (on a -Qip operation) because this field was no longer
filled. Now pkg_load fills it.
But the -Qip operation needs to be run like this : -Qip <filename>, so the
filename is already known. There is no need to display it again.
Besides, on a normal -Qi operation, the filename is not displayed either
because this information is not stored in the local database.

Errors like the following one happen regularly (for unknown reasons...) :
error: could not open file /var/lib/pacman/local//glibc-2.7-9/depends: No
such file or directory
Anyway, every time an user reported an error like that, it always seemed
like he thought the error was caused by the double /, which is obviously
wrong.
Since db->path always include a trailing /, there is no need to add one when
concatenating paths in be_files.c or add.c.
Additionally, some static strings were switched to dynamic.
And the computation of the "dbpath"/"pkgname"-"pkgversion" was refactored
in db_read, db_write and db_remove with a get_pkgpath static function.

Add a new totaldlcb callback function to libalpm and make pacman utilize it
when the TotalDownload option is enabled. This callback function is pretty
simple- it is meant to be called once at the beginning of a "list download"
action, and once at the end (with value 0 to indicate the list has been
finished). The frontend is responsible for keeping track of adding
individual file download amounts to the total xfered amount in order to

We have been using unsigned long as a file size type for a while, which
works but isn't quite correct and could easily break. Worse was probably our
use of int in the download callback functions, which could be restrictive
for packages > 2GB in size.
Switch all file size variables to use off_t, which is the preferred type for
file sizes. Note that at least on Linux, all applications compiled against
libalpm must now be sure to use large file support, where _FILE_OFFSET_BITS
is defined to be 64 or there will be some weird issues that crop up.

repo-add and db_read both assume that REPLACES and FORCE fields are in the

Note that db_write is currently only used on the local database. And the
only purpose of replaces and force in local database is for information
purpose (available on -Qi operations). So this is not a big problem.

Commit 0460038447 caused a regression when
rereading the pkgcache after updating the on-disk databases. A rewinddir
call was errantly removed.
Instead of replacing the call to rewindir, clean up this whole mess.
db_scan is used only once and with target == NULL so there was actually half
the code of db_scan which was unused. This is gone now and replaced by a
single new db_populate function.

Reference : FS#9547.
The get_filename function first tries to get the filename field from the
database, and if it doesn't find it, it tries to guess it based on the name,
version and arch.
This field was introduced in 3.0, but there are still many old entries in
the official databases without it. So the databases need to be regenerated
first before this patch can be applied.
There is a second problem with the delta code, which needs the filename for
locally installed packages too, but this field is not present in the local
db. So the delta code needs to be fixed first.

Using the graph structures that Nagy set up for dependency sorting, we now
do a similar process for deltas. Load up all of the deltas into a graph
object on which we can then apply Dijkstra's algorithm, using the new weight
field of graph struct.
We initialize the nodes weight using the base files that we can use in our
filecache (both filename and md5sum must match). The algorithm then picks
the best path among those that can be resolved.
Note that this algorithm has a few advantages over the old one:
1. It is completely file agnostic. These delta chains do not have to consist
of package files- this could be adopted to do delta-fied DBs.
2. It does not use the local_db anymore, or even care if a package or file
is currently installed. Instead, it only looks in the filecache for files
and packages that match delta chain entries.

towards something that is package (or even filename) agnostic. This will

cleaner with less of a need for snprintf() calls.
