Warning 30 warns when the same constructor/label is used in two
mutually-recursive type declarations. This warning (added in OCaml
3.12, 2010) was meaningful at the time where constructor/label
conflicts had a shadowing semantics: the "last" definition would mean,
while ideally mutually-recursive definitions should not be strictly
ordered but defined "all at once".
Since OCaml 4.01 (2013) we support type-based disambiguation of
constructor/label names and it is now common to write code such as,
say
type pattern = Var of var | ...
type expr = Var of var | ...
(no warning, of course). But warning 30 fires if you instead write
type pattern = Var of var | ...
and expr = Var of var | ...
This doesn't make much sense, and in particular it certainly makes no
sense to enable this warning by default. The present PR disables it by
default.
This commit removes support for gprof-based profiling (the -p option to ocamlopt). It follows a discussion on the core developers' list, which indicated that removing gprof support was a reasonable thing to do. The rationale is that there are better easy-to-use profilers out there now, such as perf for Linux and Instruments on macOS; and the gprof support has always been patchy across targets. We save a whole build of the runtime and simplify some other parts of the codebase by removing it.
After consultation on the core developers' list I am proposing this patch to remove support for compiler plugins.
The main motivations for removing compiler plugins are:
- They are a potential security risk.
- They increase the complexity of the build system and make maintenance of the Dynlink libraries more difficult (although actually, this complexity could probably be reduced after #2268 is merged).
- Many applications of plugins should be able to be expressed by building custom compiler drivers that link against compilerlibs.
* Remove compiler plugins and hooks
* Add new function Dynlink.unsafe_get_global_symbol but keep it outside the documented API.
* Remove otherlibs/dynlink/nodynlink.ml
* Update Changes
* Delete the deprecated vmthreads library
It was deprecated in 4.08.
* Remove the byte/native argument of init_path
It is no longer necessary.
* Error out when passing --{enable,disable}-vmthreads to ./configure

These are most likely a mistake for "type t = unit", but still valid, and lead
to quite confusing error messages afterwards because now `()` denotes two
different incompatible constructors.
In order to prepare the transition to autoconf, this commit moves the
configuration Makefile out of the config directory which will disappear
and gives it the name it will have once intstalled, namely Makefile.config.
Instead of the current print to stderr. This way it's treated the same
as other warnings: it has a position, colors, can be made an error,
disabled, goes in the expected formatter, is documented.
Nearly identical changes to:
ocaml.m, ocamlc.m, ocamlopt.m, unified-options.etex
"-safe-string" has been the default since 4.06, so the assertion that
it would be the default someday, and that "-unsafe-string" is still
the default, was incorrect.
The proposed behavior of `-config-var s` is as follows:
- if `s` is an existing configuration variable, print its value as
a string and exit with a success return value (0)
- if `s` is not an existing configuration variable, print nothing
and exit with a failure return value (non-0)
Note that we do not print a newline after the value of the
configuration variable. In particular, if the value is an empty
string, the output is undistinguishable from the output for
non-existing variables, the return value has to be considered instead.
The following alternative behaviors were considered:
- We could print a newline after the configuration value, which
would let users distinguish empty values from non-existing variables
by counting the lines of output, and would also be more pleasant for
users invoking the option from the command-line. However, the way
bash works on Windows means that $(ocamlc -config-var foo) would keep
a trailing \r in its output, and portable scripts would have to use
$(ocamlc -config-var foo | tr -d '\r') instead, which is a pain.
(This issue was pointed out by David Allsopp)
- We could print a message on the error output if the configuration
variable does not exist. This is clearer to a human user, but it is
annoying for scripts if they forget to silence the error output and
get their output mixed with our error messages. The main use of this
new feature is for scripting purposes.
* add description of the "-charset" option to the manual page of "ocamldoc"
* add description of the "-show-missed-chrossref" option to the manual page of "ocamldoc"
* add description of the "-text" option to the manual page of "ocamldoc"
Escaping strings when printing them in the toplevel has the disadvantage
of mangling unicode text:
```
\# "한글";;
- : string = "\237\149\156\234\184\128"
```
With this commit, strings are not escaped anymore, contrarily to bytes:
```
\# let cosmos = "κόσμος";;
cosmos : string = "κόσμος"
\# Bytes.of_string cosmos;;
- : bytes =
Bytes.of_string "\206\186\207\140\207\131\206\188\206\191\207\130"
```
This new behavior can be disabled dynamically by setting the environment
variable OCAMLTOP_UTF_8 to false
This change is not solely aesthetic: the mangling of unicode string may
contribute to the impression of some OCaml newcomers that Ocaml has no
support for unicode.
