If an interactive shell has its tty invalidated attempts to write to
stdout or stderr can trigger this bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=20632
Avoid that by reopening the stdio streams on /dev/null if we're getting
an ENOTTY error when trying to do things like give or take ownership of
the tty.
This includes some unrelated style cleanups but including them seems
reasonable.
Fixes#3644
This implements a standard function and bindings for editing the command
line in an external editor. This feature has been requested multiple
times in the past year with various solutions cut and pasted into those
issues. This change combines the best aspects of those solutions.
Fixes#1215
There were two places in the code that used the anti-pattern of
returning True on success else an error message. In python you should
always be able to replace `if x == True:` with just `if x:`. Which is
what the lint tool recommended. Unfortunately I didn't notice how the
return value was being used. This fixes that by changing the two
affected functions to return an error message or None on success.
This also adds `from __future__ import print_function` since the code
uses the `print(msg)` function form rather than the `print msg`
statement form. The former works by accident on python2 because the
parens are interpreted as creating parenthesized expression that
devolves to the single string inside the parens. So while the future
import isn't strictly speaking necessary it will help avoid mistakes in
the future if more complex `print()` calls are added.
Partial fix for #3620
`abbr` used to take a single argument and split in on the first space,
but 309e10e7 and predecessors altered this behaviour. Update the web
config use of abbr to the newer format.
Fixes#3620.
I had disabled having `make style-all` restyling fish scripts because a
majority of them did not conform to the style enforced by `fish_indent`.
I recently restyled most of the fish scripts with the exception of the
completion scripts. So this re-enables restyling all scripts with the
exception of completion scripts.
When I refactored the code to reduce redundancy and improve the error
messages when the config or data directories could not be used I botched
the customization of the $HOME based data path.
min_width dates back to the original full-screen pager.
After some careful inspection, the code path that uses min_width
is never executed and so the min_width machinery is useless.
Let's remove it!
Tests that exercise error paths may result in output to
stderr. This may make it look like the test failed when it did
not. Introduce should_suppress_stderr_for_tests() to suppress
this output so the test output looks clean.
This commit fixes a bug which causes that
fish -c ')'; echo $status
("Illegal command name" error) returns 0. This is inconsistent with
e.g. when trying to run non-existent command:
fish -c 'invalid-command'; echo $status
("Unknown command" error) which correctly returns 127.
A new status code,
STATUS_ILLEGAL_CMD = 123
is introduced - which is returned whenever the 'Illegal command name *'
message is printed.
This commit also adds a test which checks if valid commands return 0,
while commands with illegal name return status code 123.
Fixes#3606.
This fixes a problem with non-threadsafe errno.
Ideally, this would be the use of the AX_PTHREAD macro, but it is GPL 3+
only, which is incompatible with the GPL 2 license of fish. It also
would need extending to cover C++.
For now, fish doesn't build on anything except GCC under Solaris anyway,
so `-pthread` is the right thing to use.
Work on #3340.
Without `-pthread` specified to the compiler, errno is not threadsafe on
Solaris (as _REENTRANT is undefined, and _POSIX_C_SOURCE may not be set
until after the inclusion of <errno.h>).
Work on #3340.
On Solaris, some standard wide character functions are only contained in
the std:: namespace. The configure script now checks for these, enabling
the appropriate `uses` statements in src/common.h.
The checks are handwritten, because Autoconf's AC_CHECK_FUNC macro
always uses C linkage, but the problem only appears under C++ linkage.
Work on #3340.
This is normally handled by the build_documentation.sh script, but if
the tarball includes the documentation then that script is never run.
We should do it in both places as the Xcode build uses only the
build_documentation.sh script!
Fixes#2561.
The autoreconf step requires a newer version of automake than is
available on older versions of Debian and Ubuntu; avoid the autoreconf
step on these platforms for now.
This change increases the amount of useful information when fish is
unable to create or use its config or data directory. We now make it
clear when neither var is set or one is set to an unusable location.
Fixes#3545
