Note that this isn't technically *w*util, but the differences between
the functions are basically just whether they do the wcs2string
themselves or not.
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.
Mostly related to usage _(L"foo"), keeping in mind the _
macro does a wcstring().c_str() already.
And a smattering of other trivial micro-optimizations certain
to not help tangibly.
If the user is in a directory which has been unlinked, it is possible
for the path .. to not exist, relative to the working directory.
Always pass in the working directory (potentially virtual) to
path_get_cdpath; this ensures we check absolute paths and are immune
from issues if the working directory has been unlinked.
Also introduce a new function path_normalize_for_cd which normalizes the
"join point" of a path and a working directory. This allows us to 'cd' out of
a non-existent directory, but not cd into such a directory.
Fixes#5341
realpath() will return NULL and sets errno if it fails.
We asserted that realpath(".") does not fail. We also didn't really
check that it was successful. Made sure we'll get a perror telling
us about what went wrong if something like this happens again.
Updated tests and added test case
Fixes#5351
Limit the fish_wcstod fast path to ASCII digits only, to fix the problem
observed in the discussion for a700acadfa
where LANG=de_DE.UTF-8 would cause `test` to interpret commas instead of
periods inside floating point values.
Retrieves the fully resolved path to the currently executing fish binary
(regardless of PATH). Can be used to ensure that the same fish is
launched again from a script.
`get_executable_path()` moved from fish binary to libfish, also cleaned
up some duplicated (but differing!) definitions of PATH_MAX (which was
used by that function) in the process.
This new function performs normalization of paths including dropping
/./ segments, and resolving /../ segments, in preparation for switching
fish to a "virtual" PWD.
Migrate the mmap() logic into a new class history_file_contents_t which
will serve to encapsulate conditional logic if we choose to use read()
instead of mmap().
macOS 10.5 and earlier do not support the convention of returning
a dynamically allocated string, plus this seems like an unnecessary
malloc. Always allocate a buffer for realpath() to write into.
The POSIX standard specifies that a buffer should be supplied to
getcwd(), not doing so is undefined (or rather, platform-defined)
behavior. This was causing the getcwd errors on illumos (though not seen
on Solaris 11) reported in #3340Closes#3340
Took care of remaining issues preventing fish from building on Solaris.
Mainly caused by some assumptions that certain defines are POSIX when
they are not (`NAME_MAX`).
Moved `NAME_MAX` defines to common.h - for some reason, it was being
defined in a cpp file (`env_universal_common.cpp`) even though it is used
in multiple source files.
Now compiles on Solaris 11 with GNU Make. Still some warnings because
fish was written with GNU getopt in mind and the Solaris version doesn't
use `const char *` but rather just `char *` for getopt values, but it
builds nevertheless.
Assuming this closes#3340
Since we are including XXHash32/64 anyway for the wchar_t* hashing,
we might as well use it.
Use arch-specific hash size and xxhash for all wcstring hashing
Instead of using XXHash64 for all platforms, use the 32-bit version
when running on 32-bit platforms where XXHash64 is significantly slower
than XXHash32 (and the additional precision will not be used).
Additionally, manually specify wcstring_hash as hashing method for
non-const wcstring unordered_set/map instances (the const varieties
don't have an in-library hash and so already use our xxhash-based
specialization when calling std::hash<const wcstring>).
No longer using RAII wrappers around pthread_mutex_t and pthread_cond_t
in favor of the C++11 std::mutex, std::recursive_mutex, and
std::condition_variable data types.
Internally fish should store vars as a vector of elements. The current
flat string representation is a holdover from when the code was written
in C.
Fixes#4200
Newer versions of GCC and Clang are not satisfied by a cast to void,
this fix is adapted from glibc's solution.
New wrapper function ignore_result should be used when a function with
explicit _unused_attribute_ wrapper is called whose result will not be
handled.
