From e63366ae5e701d8e9ae33144f68e8786b092a468 Mon Sep 17 00:00:00 2001 From: Nagy Gabor Date: Sun, 18 Nov 2007 18:45:46 +0100 Subject: New remove option : -u / --unneeded (FS#6505). With --unneeded option 'pacman -R' doesn't stop in case of dependency error; it removes the needed-dependency targets from the target-list instead. See also: http://archlinux.org/pipermail/pacman-dev/2007-October/009653.html . The patch also adds a new causingpkg field to pmdepmissing_t which indicates the to-be-removed package which would cause a dependency break. This is needed, because miss->depend.name may be a provision. miss->causingpkg will be useful in -R dependency error messages too. [Xavier: renamed inducer to causingpkg, removed the _alpm_pkgname_pkg_cmp helper function as requested by Aaron. This might be added by a further commit. Other small cleanups, updated manpage and bash completion.] Signed-off-by: Chantry Xavier --- lib/libalpm/deps.c | 22 ++++++++++++++++++---- 1 file changed, 18 insertions(+), 4 deletions(-) (limited to 'lib/libalpm/deps.c') diff --git a/lib/libalpm/deps.c b/lib/libalpm/deps.c index 5c63e9d6..c08c59e9 100644 --- a/lib/libalpm/deps.c +++ b/lib/libalpm/deps.c @@ -68,7 +68,8 @@ static void _alpm_graph_free(void *data) free(graph); } -pmdepmissing_t *_alpm_depmiss_new(const char *target, pmdepend_t *dep) +pmdepmissing_t *_alpm_depmiss_new(const char *target, pmdepend_t *dep, + const char *causingpkg) { pmdepmissing_t *miss; @@ -78,6 +79,7 @@ pmdepmissing_t *_alpm_depmiss_new(const char *target, pmdepend_t *dep) STRDUP(miss->target, target, RET_ERR(PM_ERR_MEMORY, NULL)); miss->depend = _alpm_dep_dup(dep); + STRDUP(miss->causingpkg, causingpkg, RET_ERR(PM_ERR_MEMORY, NULL)); return(miss); } @@ -86,6 +88,7 @@ void _alpm_depmiss_free(pmdepmissing_t *miss) { _alpm_dep_free(miss->depend); FREE(miss->target); + FREE(miss->causingpkg); FREE(miss); } @@ -298,7 +301,7 @@ alpm_list_t SYMEXPORT *alpm_checkdeps(pmdb_t *db, int reversedeps, _alpm_log(PM_LOG_DEBUG, "checkdeps: missing dependency '%s' for package '%s'\n", missdepstring, alpm_pkg_get_name(tp)); free(missdepstring); - miss = _alpm_depmiss_new(alpm_pkg_get_name(tp), depend); + miss = _alpm_depmiss_new(alpm_pkg_get_name(tp), depend, ""); baddeps = alpm_list_add(baddeps, miss); } } @@ -311,17 +314,18 @@ alpm_list_t SYMEXPORT *alpm_checkdeps(pmdb_t *db, int reversedeps, pmpkg_t *lp = i->data; for(j = alpm_pkg_get_depends(lp); j; j = j->next) { pmdepend_t *depend = j->data; + pmpkg_t *causingpkg = alpm_list_find(modified, depend, satisfycmp); /* we won't break this depend, if it is already broken, we ignore it */ /* 1. check upgrade list for satisfiers */ /* 2. check dblist for satisfiers */ - if(alpm_list_find(modified, depend, satisfycmp) && + if(causingpkg && !alpm_list_find(upgrade, depend, satisfycmp) && !alpm_list_find(dblist, depend, satisfycmp)) { char *missdepstring = alpm_dep_get_string(depend); _alpm_log(PM_LOG_DEBUG, "checkdeps: transaction would break '%s' dependency of '%s'\n", missdepstring, alpm_pkg_get_name(lp)); free(missdepstring); - miss = _alpm_depmiss_new(lp->name, depend); + miss = _alpm_depmiss_new(lp->name, depend, alpm_pkg_get_name(causingpkg)); baddeps = alpm_list_add(baddeps, miss); } } @@ -675,6 +679,16 @@ const char SYMEXPORT *alpm_miss_get_target(const pmdepmissing_t *miss) return(miss->target); } +const char SYMEXPORT *alpm_miss_get_causingpkg(const pmdepmissing_t *miss) +{ + ALPM_LOG_FUNC; + + /* Sanity checks */ + ASSERT(miss != NULL, return(NULL)); + + return miss->causingpkg; +} + pmdepend_t SYMEXPORT *alpm_miss_get_dep(pmdepmissing_t *miss) { ALPM_LOG_FUNC; -- cgit v1.2.3-70-g09d2
