2011-06-27Ensure a file can be replaced by a directoryDan McGee1-8/+18
This addresses FS#24904. In a normal upgrade case, this replacement seems to work just fine. However, when doing a sync "replace" type upgrade, we weren't properly handling this edge case due to path comparison not ignoring trailing slashes. Fix this by pruning any trailing slashes past a certain point of file conflict resolution where we no longer need them, which allows us to safely detect cases such as now tested in the new pactest.

2011-06-27File conflict code cleanupsDan McGee1-11/+11
While researching the root cause of FS#24904, I couldn't help but clean up some of the cruft in here. A few whitespace/line-wrapping issues, but also fix shadowed variables and add some const where applicable. Signed-off-by: Dan McGee <dan@archlinux.org>

Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-16Make pmfileconflict_t type publicDan McGee1-24/+0
This removes the need to write accessor methods for every type we have, and simplifies the API. Any type that doesn't need magic* can be converted in this fashion to make it easier for frontend applications to use, as well as make it less of a pain to introduce new such structs in the future. * "magic" meaning something like pmpkg_t where values can be lazy loaded.

2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee1-0/+1
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.

2011-06-09Kill all remaining 'PATH_MAX + 1' usagesDan McGee1-3/+3
The few remaining instances were utilized for buffers in calls to snprintf() and realpath(). Both of these functions will always ensure the returned value is padded with '\0', so there is no need for the extra byte. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Remove global handle dependencies from sync/upgrade pathsDan McGee1-9/+7
This kills a lot more global handle business off. sync.c still requires the handle declaration for one reference that can't be changed yet; it will be removed in a future patch which isolates all of the necesary API changes. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Push down extern handle variable to files that need itDan McGee1-0/+3

2011-06-03Remove ALPM_LOG_FUNC macroDan McGee1-24/+0
The usefulness of this is rather limited due to it not being compiled into production builds. When you do choose to see the output, it is often overwhelming and not helpful. The best bet is to use a debugger and/or well-placed fprintf() statements. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-03-31Unify filelist operation functions in conflict checkingDan McGee1-51/+25
We had two functions that were oh so similar but slightly different. We can combine them and add some conditional operation stuff to decide what to return. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-03-21Style change: return(x) --> return xDan McGee1-31/+31
This was discussed and more or less agreed upon on the mailing list. A huge checkin, but if we just do it and let people adjust the pain will end soon enough. Rebasing should be relatively straighforward for anyone that sees conflicts; just be sure you use the new return style if possible. The following semantic patch was used to do the change, along with some hand-massaging in order to preserve parenthesis where appropriate: The semantic match that finds this problem is as follows, although some hand-massaging was done in order to keep parenthesis where appropriate: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a; @@ - return(a); + return a; // </smpl> A macros_file was also provided with the following content: Additional steps taken, mainly for ASSERT() macros: $ sed -i -e 's#return(NULL)#return NULL#' lib/libalpm/*.c $ sed -i -e 's#return(-1)#return -1#' lib/libalpm/*.c Signed-off-by: Dan McGee <dan@archlinux.org>

* Make conflict_isin() static; it is used nowhere else. * Remove does_conflict(): it turns out to be replaceable by a single call to _alpm_depcmp().

2011-02-04Read pkgcache into hashAllan McRae1-2/+2
Read the package information for sync/local databases into a pmpkghash_t structure. Provide a alpm_db_get_pkgcache_list() method that returns the list from the hash object. Most usages of alpm_db_get_pkgcache are converted to this at this stage for ease of implementation. Review whether these are better accessing the hash table directly at a later stage. Signed-off-by: Allan McRae <allan@archlinux.org>
2011-01-10Remove need for floating point division in backendDan McGee1-2/+2
All of these can be done with integer division; the only slightly interesting part is ensuring we round up like before with calling the ceil() function. We can also remove the math library from requirements; now that the only ceil() calls are gone, we don't need this anymore. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-08Fix some more simple conversion "errors"Dan McGee1-2/+2
None of these warn at the normal "-Wall -Werror" level, but casts do occur that we are fine with. Make them explicit to silence some warnings when using "-Wconversion". Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-08Use size_t for alpm_list sizesAllan McRae1-2/+2
There is a lot of swtiching between size_t and int for alpm_list sizes in the codebase. Start converting these to all be size_t by adjusting the return type of alpm_list_count and fixing all additional warnings given by -Wconversion that are generated by this change. Dan: a few more small changes to ensure things compile, adjusting some printf format string characters to accommodate the larger size on x86_64.

2010-12-13alpm: don't expose alpm_depcmpXavier Chantry1-1/+1
Either we expose all low levels function dealing with pmdepend_t (splitdep and depfree come to mind), or we don't. Since none of the tools use depcmp, I chose to remove it. In the future, we might want to expose higher level functions such as alpm_find_satisfier, or just lower level functions like splitdep and depfree together with depcmp.

2009-09-09Remove transaction typeXavier Chantry1-1/+1
This basically started with this change : /* Transaction */ 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.
2009-09-09Add a new reason field to pmconflict_t structNagy Gabor1-5/+19
Sometimes "foo conflicts with bar" information is not enough, see this thread: http://bbs.archlinux.org/viewtopic.php?id=77647. That's why I added a new reason field to our pmconflict_t struct that stores the packager- defined conflict that induced the fact that package1 conflicts with package2. I modified the front-end (in callback.c, sync.c, upgrade.c) to print this new information as well. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu>

2009-07-20Fix fileconflict004Xavier Chantry1-0/+57
When one package wants to replace a directory by a file, we check that all files in that directory were owned by that package. Additionally pacman can be more verbose when the extraction of the symlink (or file) fails. The patch to add.c looks more complex than it is, I just moved and reindented code to handle cases 10 and 11 together.

2009-04-11Fix for trans001.py (FS#9088)Nagy Gabor1-45/+45
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. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>

This has been around since at least pacman 2.9.8. Frugalware just dumped it in commit 113ec73bfcfdc, and deleting it here and running pactest shows that nothing that we have actually tested changes.
