Package: libnotmuch-dev Version: 0.18.2-1 Severity: normal Tags: patch notmuch_directory_set_mtime() sets the new mtime in the database, but doesn't update the cached value in the notmuch_directory_t object, which is what notmuch_directory_get_mtime() returns. This means that this sequence of calls: notmuch_directory_set_mtime(dir, 12345); assert(notmuch_directory_get_mtime(dir) == 12345); will fail, which can be very confusing - I was writing unit tests for a library wrapper and it took a while to figure out what was going on. Destroying the directory object and creating a new one will cause notmuch_directory_get_mtime() to return the correct value. If this is the intended behaviour it should probably be documented. If it's not, the attached patch should fix it. -- System Information: Debian Release: 8.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 3.16.0-4-686-pae (SMP w/2 CPU cores) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libnotmuch-dev depends on: ii libnotmuch3 0.18.2-1 libnotmuch-dev recommends no packages. libnotmuch-dev suggests no packages. -- no debconf information
