2011-08-19Be more robust when copying package dataDan McGee1-3/+9
This changes the signature of _alpm_pkg_dup() to return an integer error code and provide the new package in a passed pointer argument. All callers are now more robust with checking the return value of this function to ensure a fatal error did not occur. We allow load failures to proceed as otherwise we have a chicken and egg problem- if a 'desc' local database entry is missing, the best way of restoring said file is `pacman -Sf --dbonly packagename`. This patch fixes a segfault that was occurring in this case. Fixes the segfault reported in FS#25667. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Convert resolvedep() to use _alpm_depcmp_literal()Dan McGee1-5/+10
The whole first loop is trying to check literals only, so teach it to do so. Also, reorder operations to make more sense by putting the strcmp() first in the literal loop, and using a very cheap name_hash check first in the second loop. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Add an _alpm_depcmp_literal() functionDan McGee1-10/+13
This omits the finding of matching provisions and only checks the package itself against the provided dep. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Remove usages of alpm_list_next() in backendDan McGee1-1/+1
Another function call that can be replaced by a single pointer dereference. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-15Parse conflicts/provides/replaces at database load timeDan McGee1-18/+12
We did this with depends way back in commit c244cfecf654d3 in 2007. We can do it with these fields as well. Of note is the inclusion of provides even though only '=' is supported- we'll parse other things, but no guarantees are given as to behavior, which is more or less similar to before since we only looked for the equals sign. Also of note is the non-inclusion of optdepends; this will likely be resolved down the road. The biggest benefactors of this change will be the resolving code that formerly had to parse and reparse several of these fields; it only happens once now at load time. This does lead to the disadvantage that we will now always be parsing this information up front even if we never need it in the split form, but as these are uncommon fields and our parser is quite efficient it shouldn't be a big concern.

2011-08-11Add -S --recursive operationDan McGee1-0/+29
This closely matches what we had before for -R --recursive. Basically, when specifying a target (e.g., pacman), we can now recursively pull all dependencies, regardless of version specifiers and whether they are already satisfied in the local database. This could be used to update pacman on a system with an old glibc, for example, as both pacman and glibc would get pulled into the transaction. This is most useful with --needed to prevent needless reinstalls as described in the man page changes. The end goal of this change is to wire it into SyncFirst and have it be the default mode of operation there, but that belongs in a separate changeset. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee1-1/+4
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.

2011-06-03Remove 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>

2011-03-25Ensure reported missing dependencies show correct version comparisonDan McGee1-34/+38
This addresses FS#23424. The -dd backend code was introduced in commit b6ec9019d77, 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. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-03-20Style change: return(x) --> return xDan McGee1-44/+44
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>

2011-02-25Continue resolving dependencies rather than bailing on first errorDan McGee1-16/+20
This allows error messages emitted by the frontend to be a bit more descriptive and not have the annoying "well why didn't you tell me that the first time" problem. If a package had multiple missing deps, we would bail on the first one before rather than finish processing all missing dependencies, and only print one error message. Instead, continue through this entire set of missing deps and append all eventual errors. The added pactest tests this case, as the to be installed package has two missing dependencies. However, pactest does not actually test or see the difference in output from before and after, so it passes in both cases, but it is clearly visible in the logs.

2011-02-04Read pkgcache into hashAllan McRae1-4/+4
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.

2011-01-31alpm/depcmp: new NODEPVERSION flagXavier Chantry1-8/+35
This flag allows to disable version checking in dependency resolving code. depcmp_tolerant respects the NODEPVERSION flag but we still keep the original strict depcmp. The idea is to reduce the impact of the NODEPVERSION flag by using it in fewer places. I replaced almost all depcmp calls by depcmp_tolerant in deps.c (except in the public find_satisfier used by deptest / pacman -T), but I kept depcmp in sync.c and conflict.c Signed-off-by: Xavier Chantry <chantry.xavier@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-29alpm/dep: add alpm_find_dbs_satisfierXavier Chantry1-0/+22
This is a public interface for resolvedep. It looks nicer to expose it this way rather than through sync_target. This function can also be helpful for external tools as it should give good results close to how pacman select a package for satisfying a given dep. Signed-off-by: Xavier Chantry <chantry.xavier@gmail.com>
2011-01-29Add interactive provider selectionXavier Chantry1-3/+35
If there are multiple providers in one db, pacman used to just stop at the first one (both during dependency resolution or for pacman -S 'provision' which uses the same code). This adds a new conversation callback so that the user can choose which provider to install. By default (user press enter or --noconfirm), the first provider is still chosen, so for example the behavior of sync402 and 403 is preserved. But at least the user now has the possibility to make the right choice in a manual run. If one of the provider is already installed, it is picked for reinstall/upgrade, so that provision 002/003 pactest now pass. $ pacman -S community/smtp-server :: There are 3 providers available for smtp-server: 1) courier-mta 2) esmtp 3) exim Which one do you want to install?
