The stdargs based infrastucture will be used in following commits for a more general logging mechanism. The changes to notmuch-{new,search} and test/symbol-test are just to make the test suite pass. The fact that no other changes are needed is probably a sign of weakness in the test suite. --- lib/database.cc | 88 ++++++++++++++++++++++++++++++++++++++++++++--------- lib/notmuch.h | 21 +++++++++++++ notmuch-new.c | 8 +++-- notmuch-search.c | 8 +++-- test/symbol-test.cc | 6 +++- 5 files changed, 111 insertions(+), 20 deletions(-) diff --git a/lib/database.cc b/lib/database.cc index 3601f9d..4f4e871 100644 --- a/lib/database.cc +++ b/lib/database.cc @@ -343,6 +343,35 @@ notmuch_status_to_string (notmuch_status_t status) } static void +vlog_to_string (void *ctx, + char **status_string, + const char *format, + va_list va_args) +{ + if (!status_string) + return; + + if (*status_string) + talloc_free (*status_string); + + *status_string = talloc_vasprintf (ctx, format, va_args); +} + +static void +log_to_string (char **str, + const char *format, + ...) +{ + va_list va_args; + + va_start (va_args, format); + + vlog_to_string (NULL, str, format, va_args); + + va_end (va_args); +} + +static void find_doc_ids_for_term (notmuch_database_t *notmuch, const char *term, Xapian::PostingIterator *begin, @@ -602,28 +631,37 @@ parse_references (void *ctx, notmuch_status_t notmuch_database_create (const char *path, notmuch_database_t **database) { + return notmuch_database_create_verbose (path, database, NULL); +} + +notmuch_status_t +notmuch_database_create_verbose (const char *path, + notmuch_database_t **database, + char **status_string) +{ notmuch_status_t status = NOTMUCH_STATUS_SUCCESS; notmuch_database_t *notmuch = NULL; char *notmuch_path = NULL; + char *message = NULL; struct stat st; int err; if (path == NULL) { - fprintf (stderr, "Error: Cannot create a database for a NULL path.\n"); + log_to_string (&message, "Error: Cannot create a database for a NULL path.\n"); status = NOTMUCH_STATUS_NULL_POINTER; goto DONE; } err = stat (path, &st); if (err) { - fprintf (stderr, "Error: Cannot create database at %s: %s.\n", + log_to_string (&message, "Error: Cannot create database at %s: %s.\n", path, strerror (errno)); status = NOTMUCH_STATUS_FILE_ERROR; goto DONE; } if (!
