This runs build_tools/style.fish, which runs clang-format on C++, fish_indent on fish and (new) black on python.
If anything is wrong with the formatting, we should fix the tools, but automated formatting is worth it.
This reverts commit cdce8511a1.
This change was unsafe. The prior version (now restored) took the lock and
then copied the data. By returning a reference, the caller holds a
reference to data outside of the lock.
This function isn't worth optimizing. Hardly any functions use this
facility, and for those that do, they typically just capture one or two
variables.
* Convert `function_get_inherit_vars()` to return a reference to the
(possibly) existing map, rather than a copy;
* Preallocate and reuse a static (read-only) map for the (very) common
case of no inherited vars;
* Pass references to the inherit vars map around thereafter, never
triggering the map copy (or even move) constructor.
NB: If it turns out the reference is unsafe, we can switch the inherit vars
to be a shared_ptr and return that instead.
This addresses a few places where -Wswitch-enum showed one or two missing
case's for enum values.
It did uncover and fix one apparent oversight:
$ function asd -p 100
echo foo
end
$ functions --handlers-type exit
Event exit
asd
It looks like this should be showing a PID before 'asd' just like
job_exit handlers show the job id. It was falling
through to default: which just printed the function name.
$ functions --handlers-type exit
Event exit
100 asd
Prior to this fix, an "event" was used as both a predicate on which events
to match, and also as the event itself. Re-express these concepts
distinctly: an event is something that happened, an event_handler is the
predicate and name of the function to execute.
* Convert JOB_* enums to scoped enums
* Convert standalone job_is_* functions to member functions
* Convert standalone job_{promote, signal, continue} to member functions
* Convert standolen job_get{,_from_pid} to `job_t` static functions
* Reduce usage of JOB_* enums outside of proc.cpp by using new
`job_t::is_foo()` const helper methods instead.
This patch is only a refactor and should not change any functionality or
behavior (both observed and unobserved).
Prior to this fix, functions stored a string representation of their
contents. Switch them to storing a parsed source reference and the
tnode of the contents. This is part of an effort to avoid reparsing
a function's contents every time it executes.
This eliminates the "missing" notion of env_var_t. Instead
env_get returns a maybe_t<env_var_t>, which forces callers to
handle the possibility that the variable is missing.
This is the first step to implementing issue #4200 is to stop subclassing
env_var_t from wcstring. Not too surprisingly doing this identified
several places that were incorrectly treating env_var_t and wcstring as
interchangeable types. I'm not talking about those places that passed
an env_var_t instance to a function that takes a wcstring. I'm talking
about doing things like assigning the former to the latter type, relying
on the implicit conversion, and thus losing information.
We also rename `env_get_string()` to `env_get()` for symmetry with
`env_set()` and to make it clear the function does not return a string.
Running the tests on travis revealed that some compilers (or at least
with some options) call the wrong struct constructor if there is more
than one struct with the same name but differing definitions.
