This fixes apr-util with gdbm 1.14, which does not +seem to always reset gdbm_errno. + +Also make the gdbm driver return error codes starting with +APR_OS_START_USEERR instead of always returning APR_EGENERAL. This is +what the berkleydb driver already does. + +Also ensure that dsize is 0 if dptr == NULL. + +Upstream-Status: Backport[https://svn.apache.org/viewvc? +view=revision&revision=1825311] + +Signed-off-by: Changqing Li <changqing.li@windriver.com> +--- + dbm/apr_dbm_gdbm.c | 47 +++++++++++++++++++++++++++++------------------ + 1 file changed, 29 insertions(+), 18 deletions(-) + +diff --git a/dbm/apr_dbm_gdbm.c b/dbm/apr_dbm_gdbm.c +index 749447a..1c86327 100644 +--- a/dbm/apr_dbm_gdbm.c ++++ b/dbm/apr_dbm_gdbm.c +@@ -36,13 +36,25 @@ + static apr_status_t g2s(int gerr) + { + if (gerr == -1) { +- /* ### need to fix this */ +- return APR_EGENERAL; ++ if (gdbm_errno == GDBM_NO_ERROR) ++ return APR_SUCCESS; ++ return APR_OS_START_USEERR + gdbm_errno; + } + + return APR_SUCCESS; + } + ++static apr_status_t gdat2s(datum d) ++{ ++ if (d.dptr == NULL) { ++ if (gdbm_errno == GDBM_NO_ERROR || gdbm_errno == GDBM_ITEM_NOT_FOUND) ++ return APR_SUCCESS; ++ return APR_OS_START_USEERR + gdbm_errno; ++ } ++ ++ return APR_SUCCESS; ++} ++ + static apr_status_t datum_cleanup(void *dptr) + { + if (dptr) +@@ -53,22 +65,15 @@ static apr_status_t datum_cleanup(void *dptr) + + static apr_status_t set_error(apr_dbm_t *dbm, apr_status_t dbm_said) + { +- apr_status_t rv = APR_SUCCESS; + +- /* ### ignore whatever the DBM said (dbm_said); ask it explicitly */ ++ dbm->errcode = dbm_said; + +- if ((dbm->errcode = gdbm_errno) == GDBM_NO_ERROR) { ++ if (dbm_said == APR_SUCCESS) + dbm->errmsg = NULL; +- } +- else { +- dbm->errmsg = gdbm_strerror(gdbm_errno); +- rv = APR_EGENERAL; /* ### need something better */ +- } +- +- /* captured it. clear it now. */ +- gdbm_errno = GDBM_NO_ERROR; ++ else ++ dbm->errmsg = gdbm_strerror(dbm_said - APR_OS_START_USEERR); + +- return rv; ++ return dbm_said; + } + + /* -------------------------------------------------------------------------- +@@ -107,7 +112,7 @@ static apr_status_t vt_gdbm_open(apr_dbm_t **pdb, const char *pathname, + NULL); + + if (file == NULL) +- return APR_EGENERAL; /* ### need a better error */ ++ return APR_OS_START_USEERR + gdbm_errno; /* ### need a better error */ + + /* we have an open database... return it */ + *pdb = apr_pcalloc(pool, sizeof(**pdb)); +@@ -141,10 +146,12 @@ static apr_status_t vt_gdbm_fetch(apr_dbm_t *dbm, apr_datum_t key, + if (pvalue->dptr) + apr_pool_cleanup_register(dbm->pool, pvalue->dptr, datum_cleanup, + apr_pool_cleanup_null); ++ else ++ pvalue->dsize = 0; + + /* store the error info into DBM, and return a status code.
