env.cpp sets up $HOME based on the current user, if it's not inherited
from the environment. fishd_get_config should be using the same
calculated value of $HOME. To that end, move universal variable
initialization to after $HOME is set up, and read the value from the
fish environment instead of using getenv().
Fixes #1725.
|
|
|
|
|
|

If $HOME is unset in the environment, fish calculates it with
getpwnam(). However, it wasn't being exported. Just like the $USER
calculation, $HOME should probably be exported, because everyone will
assume that it's an environment variable (as opposed to an unexported
global variable).

`exec` removes fish from the shell "stack", so SHLVL needs to be
decremented to match. This means `exec fish` will result in the same
SHLVL in the new fish instance.
Also tweak the SHLVL logic to interpret an environment SHLVL of "3foo"
as garbage instead of as the value "3".
Fixes #1693.
|
|
|
|
|
| |
Due to being read-only, SHLVL wasn't being incremented properly for
recursive invocations of fish.

Repurpose the ENV_INVALID return value for env_set(), which wasn't
currently used by anything. When a bad value is passed for the 'umask'
key, return ENV_INVALID to signal this and print a good error message
from the `set` builtin.
This makes `set umask foo` properly produce an error.

This stops unconditionally setting values for HOME and USER,
if we find those values in the environment. It also saves about 16KB
on OS X, which getpwuid allocates.

Instead of introducing a new local scope at the point of `set`, merely
push a new local scope at the end of env_init(). This means we have a
single toplevel local scope across the lifetime of the fish process,
which means that
set -l foo bar
echo $foo
behaves as expected, without modifying the global environment.
|
|
|
|
|

The mode restricts the scope in which the variable is searched for.
Use this new restricted scope functionality in the `set` builtin. This
fixes `set -g` to not show local shadowing variable values, and also
allows for scoped erasing of slices.

When attempting to set a readonly or electric variable in the local or
universal scopes, print an appropriate error. Similarly, print an error
when setting an electric variable as exported. In most cases this is
simply a nicer error instead of the 'read-only' one, but for the 'umask'
variable it prevents `set -l umask 0023` from silently changing the
global value.

They're dynamically calculated, so they qualify. This also removes them
from the list of exported global variables, because they're actually not
exported.
|
|
|
|
|
|

|

When using the `set` command with the -l flag, if we're at the top
level, create a temporary local scope. This makes query/assignment
behavior be consistent with the value-printing behavior.
This works by marking the current block as needing to pop the
environment if a local scope was pushed. I assume this is safe to do. I
also assume the current block is the right one to modify, rather than
trying to walk up the stack to the root.

env_exists() wasn't properly handling multiple scopes in some cases,
notably with readonly/electric variables. Rewrite it to operate in a
more straightforward fashion.

|

When initializing fish, ignore any inherited environment variables that
match any of the readonly or electric variable names.
This prevents really weird behavior when e.g. fish is launched with
COLUMNS already set to something. In that case, testing $COLUMNS within
fish behaves normally, but any subprocesses get the value that fish
itself had inherited.

Now fish shell stores version is a small file called by other files.
This means that a slight change which modifies one file won't cause
many of files to recompile.
The compilation unit is intentionally small, this is by design. The
smaller it is, the faster it will recompile, and it will be compiled
a lot.

This commit hooks the Makefile up to generate a FISH_BUILD_VERSION
symbol and kills off PACKAGE_VERSION in .cpp files.
It also modifies the tarball generation script to add the necessary
version file for releases.

On FreeBSD, compilation complains that "this file includes
<sys/termios.h> which is deprecated, use <termios.h> instead". On Linux
and FreeBSD, <sys/termios.h> literally just pulls in <termios.h>. On OS
X and Solaris, <termios.h> pulls in <sys/termios.h>.
<termio.h> doesn't exist on FreeBSD or Mac OS X, and on Linux is marked
as deprecated and just includes <termios.h>. It does exist on Solaris,
but no `struct termio` is ever actually used in the codebase.

modify PATH in share/config.fish. Introduced variable fish_user_paths, and a glue function __fish_reconstruct_path that splices together PATH with fish_user_paths. Changed fish to no longer validate changes to PATH unless the paths are new (i.e. don't recheck what's already there). Modified certain sets to store const wchar_t instead of wcstring to save a few allocations.
