Perform an ad-hoc code signing with the hardened runtime.
This ensures that these executables can pass notarization.
The code signing ID is controlled by the MAC_CODESIGN_ID CMake
cache variable.
This commit recognizes an existing pattern: many operations need some
combination of a set of variables, a way to detect cancellation, and
sometimes a parser. For example, tab completion needs a parser to execute
custom completions, the variable set, should cancel on SIGINT. Background
autosuggestions don't need a parser, but they do need the variables and
should cancel if the user types something new. Etc.
This introduces a new triple operation_context_t that wraps these concepts
up. This simplifies many method signatures and argument passing.
CMake sets these flags to sane defaults depending on which compiler
you're using, so overriding them isn't very nice.
For example:
with g++, I get
-- Debug: -g
-- RelWithDebInfo: -O2 -g -DNDEBUG
-- MinSizeRel: -O2 -g -DNDEBUG
-- Release: -O3 -DNDEBUG
and with MSVC you get something like
-- Debug: /MDd /Zi /Ob0 /Od /RTC1
-- RelWithDebInfo: /MD /Zi /O2 /Ob1 /DNDEBUG
-- MinSizeRel: /MD /Zi /O2 /Ob1 /DNDEBUG
-- Release: /MD /O2 /Ob2 /DNDEBUG
This adds support for `fish_trace`, a new variable intended to serve the
same purpose as `set -x` as in bash. Setting this variable to anything
non-empty causes execution to be traced. In the future we may give more
specific meaning to the value of the variable.
The user's prompt is not traced unless you run it explicitly. Events are
also not traced because it is noisy; however autoloading is.
Fixes#3427
Not -Werror, just the warnings themselves.
Let's just see what happens. It's warning-free on my system.
Worst case we disable it again, better case we refine the set.
This adds a new mechanism for logging, intended to replace debug().
The entry points are FLOG and FLOGF. FLOG can be used to log a sequence of
arguments, FLOGF is for printf-style formatted strings.
Each call to FLOG and FLOGF requires a category. If logging for a category
is not enabled, there is no effect (and arguments are not evaluated).
Categories may be enabled on the command line via the -d option.
I did not realize builtins could safely call into the parser and inject
jobs during execution. This is much cleaner than hacking around the
required shape of a plain_statement.
This new file is supposed to encapsulate all of the logic around
reacting to variable changes, as opposed to the environment core.
This is to help break up the env.cpp monolith.
In tests we would like to arrange for an executable to invoke certain
system calls, e.g. to claim or relinquish control of the terminal. This is
annoying to do portably via e.g. perl. fish_test_helper is a little
program where we can add custom commands to make it act in certain ways.
As it turns out it didn't work much better, and it fell behind in
support when it comes to things that wcwidth traditionally can't
express like variation selectors and hangul combining characters, but
also simply $fish_*_width.
I've had to tell a few people now to rebuild with widecharwidth after
sending them on a fool's errand to set X variable.
So keeping this option is doing our users a disservice.
topic_monitor allows for querying changes posted to one or more topics,
initially sigchld. This will eventually replace the waitpid logic in
process_mark_finished_children().
Comment from the new header:
Topic monitoring support. Topics are conceptually "a thing that can
happen." For example, delivery of a SIGINT, a child process exits, etc. It
is possible to post to a topic, which means that that thing happened.
Associated with each topic is a current generation, which is a 64 bit
value. When you query a topic, you get back a generation. If on the next
query the generation has increased, then it indicates someone posted to
the topic.
For example, if you are monitoring a child process, you can query the
sigchld topic. If it has increased since your last query, it is possible
that your child process has exited.
Topic postings may be coalesced. That is there may be two posts to a given
topic, yet the generation only increases by 1. The only guarantee is that
after a topic post, the current generation value is larger than any value
previously queried.
Tying this all together is the topic_monitor_t. This provides the current
topic generations, and also provides the ability to perform a blocking
wait for any topic to change in a particular topic set. This is the real
power of topics: you can wait for a sigchld signal OR a thread exit.
This represents a "resolved" io_chain_t, where all of the different io_data_t
types have been reduced to a sequence of dup2() and close(). This will
eliminate a lot of the logic duplication around posix_spawn vs fork, and pave
the way for in-process redirections.

Since fish began resolving symlinks it broke the running-from-build-dir
detection in fish.cpp if the build directory were a symlink (which is
common on some platforms where the default user HOME directory is a
symlink in the first place, e.g. FreeBSD).
Load fish docs and configuration out of the source and/or build
directories rather from the installed paths when running directly out
of the cmake build directory.
Closes#5255.
Default to RelWithDebInfo (-O2 -g) if no custom CMAKE_BUILD_TYPE is
defined. Also add flags for use with CMAKE_BUILD_TYPEs Debug, Release,
and RelWithDebInfo.
This introduces a new type features_t that exposes feature flags. The intent
is to allow a deprecation/incremental adoption path. This is not a general
purpose configuration mechanism, but instead allows for compatibility during
the transition as features are added/removed.
Each feature has a user-presentable short name and a short description. Their
values are tracked in a struct features_t.
We start with one feature stderr_nocaret, but it's not hooked up yet.
* Make wcwidth configurable
This adds the cmake option "INTERNAL_WCWIDTH" (to be set to "ON" or
"OFF") and the configure option --[en,dis]able-internal-wcwidth.
Both default to enabling our fallback, but can be set to use the system's wcwidth again.
Sequel to #4554.
See #4571, #4539, #4609.
On my system, this would fix#4306.
