This also involves adding a flag to constructors and case alternatives
in CExp which say whether it's a NIL or CONS. Currently, we only do this
for Prelude.List, which already has an effect, but soon I'll extend this
to work for all list-shaped things and rather than being hard coded. We
could also imagine spotting other shapes (enumerations especially) for
code generators to spot as they see fit.
This will require code generators to be fixed to recognise the new
ConInfo flag, but you can just ignore it.
Bootstrap code also updated, because we don't currently have a way of
having separate support.ss/rkt for the bootstrap and normal builds!
As a relict of the REPL output, several `<br>` tags where introduced,
where they are not needed or even permitted. This led to some spacing
issues (sometimes the docstring was closer to the next term than to the
one above that it actually described).
To counter the removed forced newlines, some extra margin is added below
each declaration.
As a side-effect, this also makes the W3 "Nu Html Checker" happy.
This adds new `Int8`, `Int16`, `Int32` and `Int64` data types
to the compiler, thus working towards properly specified integer
types as discussed in #1048.
In addition, the following changes / corrections are made:
* Support casts from `Char`, `String`, and `Double` to all integer
types (and back). This fixes#1270.
* Make sure that all casts to limited-precision integers are properly
bounds checked (this was not the case so far for casts from `String`
and `Double` to `Int`)
* Add a thorough set of tests to make sure all bounds checks work
correctly for all supported casts and arithmetic operations
This change adds logic to set up sockaddr correctly for connect and
bind, handles the AF_UNIX case for getSockAddr and expands the existing
test to cover unix sockets.
Change the support code for directory creation so that it sets all
permission bits (ugo=rwx). The process's currently active umask will be
subtracted from these permissions, which leads to the result that (for a
standard umask of "022") directories are created with a mode of "0755".
So by default, directories created with `prim__createDir` are now also
group-executable and other-executable by default.
Previous behaviour was to create the directories readable for group and
other, but not executable (mode "744"), and thus inaccessible to anyone
except the owner.
Written by Volkmar Frinken (@vfrinken). This is intended as a
lightweight (i.e. minimal dependencies) code generator that can be
ported to multiple platforms, especially those with memory constraints.
It shouldn't be expected to be anywhere near as fast as the Scheme back
end, for lots of reasons. The main goal is portability.
The Network.Socket.Data code previously used hardcoded constants manually read
from auto-generated C source code, however these constants are specific to
Linux. The original code looked like this:
export
ToCode SocketFamily where
-- Don't know how to read a constant value from C code in idris2...
-- gotta to hardcode those for now
toCode AF_UNSPEC = 0 -- unsafePerformIO (cMacro "#AF_UNSPEC" Int)
toCode AF_UNIX = 1
toCode AF_INET = 2
toCode AF_INET6 = 10
The AF_INET6 constant is correct on my Debian 10 laptop:
molly on flywheel ~> grep -rE '^#define AF_INET6' /usr/include
/usr/include/x86_64-linux-gnu/bits/socket.h:#define AF_INET6 PF_INET6
molly on flywheel ~> grep -rE '^#define PF_INET6' /usr/include
/usr/include/x86_64-linux-gnu/bits/socket.h:#define PF_INET6 10 /* IP version 6. */
However, this is not the case on an OpenBSD machine:
spanner# grep -rE '^#define[[:space:]]+AF_INET6' /usr/include
/usr/include/sys/socket.h:#define AF_INET6 24 /* IPv6 */
This commit adds accessor functions to the C runtime support library for
retrieving the values of these macros as they appear in the system libc header
files, which can then be invoked using the normal C FFI machinery.
