`try_malloc` was changed in 8bb2c2c074 to
avoid a warning when size is 0. Then, this improves some things on that:
- Use local vars instead of changing parameters.
- Homogenize style for other related functions.
xsel and xcopy may be available even if a valid X display is not. Also,
the availability of X may change at any time, so check on each
invocation.
Closes#1509.
The $GDB env var can be set to run tests under gdbserver. If $VALGRIND is also
set, it will add the --vgdb=yes command-line option to valgrind instead of
starting gdbserver.
See https://github.com/neovim/neovim/issues/1519 for failure report.
Cause : In OSX, /tmp is a symbolic link to /private/tmp, which causes
expected and got results different because of implicit
resolution.
Solution : Resolve path before setting expected value.
Two new functions, `event_enable_deferred()`/`event_disable_deferred()` have to
be called by code that is capable of handling asynchronicity. User-dialog states
like "press ENTER to continue" or the swap file confirmation no longer will
generate K_EVENT.
Nvim wasn't exiting cleanly in some job tests due to errors.
This can't be noticed until the next commit, which will perform a refactoring to
selectively process K_EVENT, so the `qa!` command executed at the end of each
test blocks forever if there are errors which require the user to press ENTER(in
that state Nvim no longer will process events).
The vim_input function accepts raw terminal input and so is better to emulate
real user, especially because it is not deferred as vim_feedkeys.
Using this function required a number of changes:
- expect() was refactored to use curbuf_contents()
- The vim_eval function in request() was moved to curbuf_contents(). For most
cases this is enough(we only care for synchronizing api calls with user input
when verifying buffer contents).
- <C-@>(NUL) is preprocessed before being passed to replace_termcodes.
- Legacy test 4 had a bug that only became visible when using vim_input, it is
fixed now.
- An extra blank line deletion was required for test 101
The last two items show that vim_feedkeys because it is not 100% equivalent to
receiving terminal input.
Problem : Assigned value is garbage or undefined @ 12578.
Diagnostic : Multithreading issue.
Rationale : Error can only occur if global `provider_call_nesting` is
changed while function is executing.
Resolution : Use local copy of global.
Problems : Null pointer argument in call to memory copy function
@ 6465.
Null pointer argument in call to memory copy function
@ 6475.
Diagnostic : Multithreading issues.
Rationale : Problem occurs if globals `enc_utf8` and `enc_dbcs` are
modified while function is executing.
Resolution : Use local copy of globals.
Problem : Dereference of null pointer @ 18841.
Diagnostic : False positive.
Rationale : Suggested error path takes `reanimate` branch at 18827,
assigning `rettv = current_funccal->rettv`. Then,
inmediately after, it supposes rettv is null, which cannot
happen, since current_funccal->rettv should always be non
null.
Resolution : Assert current_funccal->rettv non null.
Problem : Out-of-bound array access @ 18737.
Diagnostic : False positive.
Rationale : Situation is intentional. `dictitem_T` is a prefix all dict
items whill share, but actual size of each item will be
different depending on its key length. `di_key` array field
is declared of size 1 just to have a field name, but real
size will vary for each item.
Resolution : Make analyzer ignore it.
This could be refactored to use C99-allowed variable length
arrays, but eval.c is bound to dissappear, so no effort is
done in that sense.
