Subject: [PATCH 1/4] printoperation: fix case where operation may complete
|
||||
multiple twice
|
||||
|
||||
If we are the final backend, then after removing ourselves there is no
|
||||
backend remaining. We will schedule the idle even if it has already been
|
||||
scheduled. This idle is required to run exactly once and executing it
|
||||
twices results in a double free that crashes loupe when printing. It
|
||||
also causes the user callback to execute twice, which could cause
|
||||
similar problems.
|
||||
|
||||
Fixes #6122

Subject: [PATCH 2/4] printoperation: fix another case where operation may
|
||||
complete twice
|
||||
|
||||
This is a little tricky. At first, I thought we had a codepath where we
|
||||
fail to schedule the idle that completes the print operation: if we take
|
||||
the gtk_print_backend_printer_list_is_done path for each printer
|
||||
backend, then printer_list_done_cb() is never executed and we never
|
||||
schedule the idle. But in fact, in this case, then backends == NULL at
|
||||
the bottom of find_printer(), and we'll schedule the idle there, so it's
|
||||
OK. Except it's not really OK, because we'll schedule it even if a
|
||||
printer was already found, resulting in the callback completing twice
|
||||
and a double free.
|
||||
|
||||
Simplify this. Schedule the idle in find_printer() only if there are
|
||||
*initially* no backends, not also if all backends are immediately ready
|
||||
and already removed from consideration. Instead, always call
|
||||
printer_list_done_cb() for every backend in find_printer_init(). After
|
||||
the previous commit, printer_list_done_cb() will schedule the idle when
|
||||
appropriate.
|
||||
|
||||
printer_list_done_cb() additionally disconnects signals that we did not
|
||||
connect in this codepath, but it does so using
|
||||
g_signal_handlers_disconnect_by_func, which is harmless. Otherwise, the
|
||||
only extra work it's doing is scheduling the idle, and that's exactly
|
||||
what find_printer_init() is missing.

Subject: [PATCH 3/4] printoperation: add some assertions
|
||||
|
||||
Let's assert that we schedule the idle callback exactly once.
|
||||
|
||||
These assertions are not perfect because if the callback executes before
|
||||
we schedule it, then the assertion itself would be a use-after-free,
|
||||
since I'm using the PrinterFinder to track whether the callback that
|
||||
frees it has been scheduled. But in practice when using loupe's print
|
||||
dialog, I was noticing the callback scheduled twice before it was
|
||||
executed. The assertion would have caught this problem.
