Avoid errors if the socket enters the TIME_WAIT state and we need to
re-execute this test before the OS releases it.
This problem was not really a problem before since the accept()-ed
socket was never closed on the server-side.
The overlap between files and sockets is minimal and lumping them
together means supporting only a small subset of the functionalities
provided by the OS.
Moreover the socket and file handles are not always interchangeable: on
Windows one should use Winsock's close() call rather than the one used
for common files.
This will enable code to perform version checks and make it easier to
support multiple versions of Zig.
Within the SemVer implementation, an intermediate value needed to be
coerced to a slice to workaround a comptime bug.
Closes#6466
Zig's format system is flexible enough to add custom formatters. This PR removes the new z/Z format specifiers that were added for printing Zig identifiers and replaces them with custom formatters.
* std.ArrayList gains `moveToUnmanaged` and dead code
`ArrayListUnmanaged.appendWrite` is deleted.
* emit_h state is attached to Module rather than Compilation.
* remove the implementation of emit-h because it did not properly
integrate with incremental compilation. I will re-implement it
in a follow-up commit.
* Compilation: use the .codegen_failure tag rather than
.dependency_failure tag for when `bin_file.updateDecl` fails.
C backend:
* Use a CValue tagged union instead of strings for C values.
* Cleanly separate state into Object and DeclGen:
- Object is present only when generating a .c file
- DeclGen is present for both generating a .c and .h
* Move some functions into their respective Object/DeclGen namespace.
* Forward decls are managed by the incremental compilation frontend; C
backend no longer renders function signatures based on callsites.
For simplicity, all functions always get forward decls.
* Constants are managed by the incremental compilation frontend. C
backend no longer has a "constants" section.
* Participate in incremental compilation. Each Decl gets an ArrayList
for its generated C code and it is updated when the Decl is updated.
During flush(), all these are joined together in the output file.
* The new CValue tagged union is used to clean up using of assigning to
locals without an additional pointer local.
* Fix bug with bitcast of non-pointers making the memcpy destination
immutable.
In strictly conforming C, identifiers cannot container dollar signs.
However GCC and Clang allow them by default, so translate-c should
handle them. See http://gcc.gnu.org/onlinedocs/cpp/Tokenization.html
I encountered this in the wild in windows.h
Fixes#7585
