Otherwise, arguments get split at spaces.
This is the same quoting that the Win32 implementation of
Unix.create_process does.
A test was added.

Some file systems maintain time stamps with sub-second resolution, up
to nanosecond resolution. When converting from a "(seconds, nanoseconds)"
timestamp to a floating-point timestamp, rounding to nearest can produce
"seconds + 1" as a result, i.e. the integer part of the FP timestamp
is not equal to "seconds". As described in #9490, this is a problem
in some cases.
This commit implements a more careful conversion of "(seconds,
nanoseconds)" pairs to FP timestamps so that the integer part of the
FP result is always "seconds".
Both the otherlibs/unix and the otherlibs/win32unix implementations are affected
and corrected.
Closes: #9490
Before, each head construction had a `make_<foo>_matching` construct that
was responsible for three things:
- consuming the argument from the argument list
(the "argument" is a piece of lambda code to access
the value of the current scrutinee)
- building arguments for the subpatterns of the scrutinee
and pushing them to the argument list
- building a `cell` structure out of this, representing a head group
during compilation
Only the second point is really specific to each construction.
This refactoring turns this second point into a construct-specific
`get_expr_args_<foo>` function (similarly to `get_pat_args_<foo>`),
and moves the first and third point to a generic `make_matching`
function.
Note: this commit contains a minor improvement to the location used to
force (lazy ..) arguments.
OCaml's signal handlers need to know the state of the processor when the signal was received. The approach standardized by the Single Unix specification is to use 3-argument signal handing functions and the SA_SIGINFO flag to sigaction. However, as the Linux man page for sigaction says,
Undocumented:
Before the introduction of SA_SIGINFO, it was also possible to get some
additional information, namely by using a sa_handler with a second
argument of type struct sigcontext. See the relevant Linux kernel
sources for details. This use is obsolete now.
For historical reasons, the i386, PowerPC and s390x Linux ports of OCaml still use the undocumented, obsolete approach, while the other Linux ports use the modern SA_SIGINFO approach.
For consistency and future-proofing, this PR updates the i386, PowerPC64, and s390x Linux ports to use the modern approach to signal handling. PowerPC32 was left as before because of technical subtleties and lack of hardware to test changes.
The new code for PowerPC 64 bits includes the trick proposed in PR#1795 to support Musl in addition to Glibc on ppc64le.
On FreeBSD, libbfd is - similarly to OpenBSD - not installed by default, but
can be added via the devel/libbfd port. This will install libbfd into the
/usr/local prefix, thus configure needs to look there for include and library
caml_alloc returns initialised blocks for tag < No_scan_tag. Otherwise,
initialise the blocks as necessary.
For Abtract_tag, Double_tag and Double_array_tag, the initial contents
are irrelevant.
Uninitialised Custom_tag objects are difficult to use correctly. Hence,
reject custom block allocations through Obj.new_block.
For String_tag, the last byte encodes the string length. Hence, reject
zero-length string objects. Initialise the last byte which encodes the
length to ensure non-negative lengths for uninitialised strings.

The instrumentation code in the instrumented runtime was replaced
with new APIs to gather runtime statistics and output them in a new format
(Common Trace Format).
This commit also exposes new functions in the Gc module to pause or resume
instrumentation during a program execution (Gc.eventlog_pause and
Gc.eventlog_resume).
Use a variable-length encoding (suggested by @stedolan) for dimensions that supports dimensions up to 2^64-1 each.

It's not just on Windows that the length of the command passed to Sys.command
can exceed system limits:
- On Linux there is a per-argument limit of 2^17 bytes
(the whole command is a single argument to /bin/sh)
- On macOS with default parameters, the limit is between 70000 and 80000
- On BSDs with default parameters, the limit is around 2^18.
In parallel, response files (@file) are supported by all the C compilers
we've encountered: GCC, Clang, Intel's ICC, and even CompCert. They all
seem to follow quoting rules similar to that of the native shell
for the contents of the response file.
This commit forces the use of a response file when the total size of
the arguments to the linker is greater than 2^16.
Arguments passed via a response file are quoted using Filename.quote
as if they were passed on the command line.

* Don't include stdio.h in caml/misc.h
There is no need to include stdio.h in caml/misc.h
This seems to have happened by accident in commit cddec18fde
On OpenBSD, stderr and stdout are macros defined in stdio.h
ppx_expect uses stderr and stdout as identifiers in
collector/expect_test_collector_stubs.c where caml/misc.h is included.
This confuses the C compiler, because the macro will get expanded where an identifier is expected.
* Remove fallback NULL definition in caml/misc.h
ISO C guarantees that NULL is defined in <stddef.h>
* include missing stdio in tests/compatibility/stub.c
(This commit is more tricky than the previous ones in the patchset
and requires a careful review.)
This refactoring clarifies and simplifies the specialize_matrix logic
by getting rid of the OrPat exception used in a higher-order
way (or sometimes not used in certain matchers, when it is possible to
"push" the or-pattern down in the pattern). Instead it uses an
arity-based criterion to implement the or-pattern-related logic once
in the specializer, instead of having to implement it in each
matcher. As a result, the compiler improves a bit as it will push
or-patterns down during specialization in valid situations that were
not implemented before -- probably because they are not terribly
important in practice: all constant and arity-1 constructs benefit
from optimized or-pattern handling, in particular the following are
new:
- lazy patterns
- non-constant polymorphic variants
- size-one records and arrays
We don't want to record the state of the file system at the start
of the compilation in the compiled files.
Consequently, we only add persistent modules to the env summary
if they have an observable action on the initial environment.
This is only the case if they shadow a non-persistent module of the
initially opened library (which can only be Stdlib currently).
Alpine Linux and perhaps other musl-based Linux distributions produce
position-independent executables (PIEs) by default. If non-PIC object
files are given to the linker, it silently produces a wrong executable
that crashes when run. This is the case for ocamlopt-generated code,
which by default is not PIC except on amd64 (x86_64) and s390x (Z systems).

Fix tail-call optimisation with a mutable ref
(Clet_mutable was not recognized properly in tail position.)
Add a test for tail-call optimisation with a mutable ref
In recent FreeBSD, `cc` is Clang and `ld` is LLD, the LLVM linker, but
`as` is still GNU binutils. Moreover, Clang contains its own
assembler and does not call `as`. Consequently, object files produced
by invoking `as` directly are slightly different from those produced
by `cc`.
This can cause obscure errors such as issue #9068: `ld -r` fails when
combining objects produced by `as` and objects produced by `cc`.
The workaround is to use `cc` as the assembler. We already did that
for the ARM and ARM64 targets, but #9068 shows that it is necessary
for AMD64 too. Just use `cc` as assembler for all FreeBSD targets.
Similar issues were reported under Linux when clang and LLD are used
instead of GCC and binutils. We already used clang as the preprocessed
assembler in this case. Also use clang as the assembler in this case.
Closes: #9068
This commit reverts c1a7ace (originally c545e04), which was a
temporary fix that is no longer needed because it was superseded by
#6608.
The temporary fix caused `{expr with lbl1 = e1; ... }` to not evaluate
`expr` if all labels of its type are overriden. As reported in #7696
this is not desirable. Reverting the temporary fix causes `expr` to
be evaluated always.
As a consequence, a corner case of value "let rec" is no longer accepted.
The corresponding test was updated.
Closes: #7696
This commit exposes all extension constructors when looking up for
a construction with a given type in the environment.
This makes constructor disambiguation work for extension constructors.
Going one step further, when the name of an extension constructors
is misspelled, we cannot rely on the type to find all possible
names. However, since we are in an error path, we have some
path at hand.
Thus, this commit alters the "lookup_from_type" function in the
Constructor module to make it scan the whole environment for
extension constructors with the right type.
This commit should not change anything for labels and standard constructors.
On my machine, running the whole testsuite generates 1.5Gio of test
data. I have 11 workdirs for the OCaml repository (versions from 4.08
to trunk, plus several experimental workdirs); at any point in time
there can be more than a dozen gibibytes of test data on my disk, and
this is too much.
I use the test data saved by ocamltest when a test fails, to diagnose
the failure. I don't remember ever looking at the test data of
a succesful test.
The present patchset changes ocamltest to, by default, discard the
test directory of succesful tests -- the test artefacts are kept only
when there is a failure.
If one wishes to preserve the test data of succesful tests, one should
explicitly pass the -keep-test-dir-on-success flag. The
testsuite/Makefile is then changed to pass this flag if the user set
the KEEP_TEST_DIR_ON_SUCCESS variable to a non-empty value.
The Gc.Memprof module provides a low-level API, that will hopefully be
paired with user libraries that provide high-level instrumentation
choices.
A natural question is: how are the higher-level API going to expose
their choice of instrumentation to their users? With the current
Memprof.start API (before this patch), they would have to either
provide their own `start` function wrapping Memprof.start, or provide
a tuple of callbacks for to their users to pass to Memprof.start
themselves.
val start : params -> unit
(* or *)
val callback : params ->
((allocation -> foo option) * (allocation -> bar option) * ... )
With an explicit record, it is easier for libraries to expose an
instrumentation choice (possibility parametrized over
user-provided settings):
val tracker : params -> (foo, bar) Gc.Memprof.tracker
In addition, providing a record instead of optional parameters makes
it much easier to provide "default settings" (helper functions) that
instantiates the types `'minor` and `'ḿajor`, see for example
`simple_tracker` in this patch (which stores the same information for
the minor and major heap, and does not observe promotion), or to later
define checking predicates that can verify that a given choice of
callbacks is sensible (for example: providing a major-dealloc callback
but no promotion callback (dropping all tracked value on promotion) is
probably not a good idea).
Bootstrap: to avoid requiring an awkward bootstrap, this commit keeps
the (now unused) function caml_memprof_start_byt unchanged -- it is
used in the bootstrap binaries, so removing it would break the
build. The intention is to remove it in the following commit.
* Move driver code from Cmt2annot to Read_cmt

Switch ocamldebug to compiler-libs in order to avoid hidden dependencies issue.
In particular, the Env module is only fully initialized after the Typemod and Includemod modules have been linked. Calling `Env.find_type` before that initialization may result in an assert false when functor-derived types are involved.
There's no need for allocation on amd64 to clobber the %rax register. It's only used in one case (-compact out-of-line allocation of >3 words), and only used there to do a single subtraction. That subtraction can be done by the caller at no code size penalty, freeing up %rax.
Inside amd64.S functions, %r11 can be used instead of %rax as temporary. %r11 is destroyed by PLT stub code, so on ELF platforms it costs nothing to use.
When building for the first time, the only requirement is that generated
header files have been built (jumptbl.h, version.h and opnames.h).
Detailed dependency information is only required when headers have been
edited.
COMPUTE_DEPS in Makefile.config controls whether C dependency
information should be generated on a per-file basis. This variable is
controlled by a new --disable-dependency-generation in configure which
is enabled for Git checkouts and disabled for tarballs (i.e. releases).
The Microsoft C compiler (cl) cannot generate dependencies in a
consistent way which we can consume, so for a Git checkout configure
searches for an additional C compiler in order to compute dependencies.
This is obviously not required for a user-build.
As a result, the MSVC port can now safely run make alldepend, since only
OCaml dependency information is committed to the repo after this change.
CI does not need to waste time testing the dependency information,
because it only tests a single build. A single Travis job has been added
which tests the build system code to generate the dependency information
(and provides a single `make -j` run in CI, although Inria's CI also
tests parallel building continuously).
This commit uses the previously computed set of options for linking
dynamic libraries (DLLIBS) in stead of hard-coding "-ldl" when trying
to find which libraries to link to get BFD support.
For instance, this fixes the build on OpenBSD64 where the use of
"-ldl" caused an error.

This commit adds a function in Printtyp for searching elements of
the printing environment without reading cmis.
This function is used to ensure that the printing of types does not
trigger unrelated errors by trying to access cmis on the file system.
In presence of -annot, the type printer can be requested to print the
inner path of inline records (i.e "t.A"). Before this commit, the
printing of these paths could trigger a lookup to a module with a
invalid name "t".
If this lookup fails this is fine.
However, if there is a cmi file in the environment sharing the name "t",
the lookup can partially succeed (since cmi are not required to start
with a capital letter) until we compare the module name stored in the
cmi with the requested module name.
Obviously, the valid module name "T" of the cmi cannot match the invalid
module name "t" that was requested, and the cmi reader raises a wrong
module file name error.
This commit avoids this whole process by detecting in the type printer
when we are printing an inlined record type constructor.
Printexc.uncaught_exception_handler ceases to be an option ref and becomes
a ref to the handler function initialized to
Printexc.default_uncaught_exception_handler.
This includes two changes: first, in bytegen.ml, we add a pseudo-event after every allocation or closure instruction. Second, in the interpreter, we save the current PC in the interpreter stack in [Setup_for_gc].
This lets users write code that is robust to the addition of new
geometry fields.
Format.(pp_update_geometry ppf (fun geo -> {geo with ...}))
Today the only way to set the geometry is
Format.pp_set_geometry ppf ~margin ~max_indent
we cannot add optional parameters after the [ppf] argument, and adding
new labeled parameters would break user code.
(Also: it's often convenient to work with the record directly, for
example to reset a previous geometry saved with [pp_get_geometry];
this is indirectly provided by [pp_update_geometry].)
They are somewhat difficult to handle for native allocations, and it is not clear how useful they are. Moreover, they are easy to add back since [Gc.Memprof.allocation] is a private record.
This PR was tested with also the -dsel, -dlinear output (also fixed to
not-print locations), but the output is architecture-dependent so this
part of the test was removed.
We need to make sure they do not share a page with code, otherwise the
GC and the polymorphic hash and comparison functions will follow code
pointers and potentially trigger a segfault.
The ocamltest modules depend on core-compiler modules and get linked
with compilerlibs archives, but those dependencies were not recorded
in the makefile, leading to incremental build errors.
(A particular error I encountered is that ocamltest/Ocaml_actions now
depends on Lambda through Cmo_format, but was not correctly rebuilt
after Lambda changes, leading to link-time failure when linking
ocaml_actions.cmo and ocamlcommon.cma together.)
This commit adds dependencies on the compilerlibs archives, as a proxy
for the corresponding compiler modules.
Before this PR, dynlink_compilerlibs/foo.cmi would not depend on
dynlink_compilerlibs/foo.mli, resulting in object files not being
properly recomputed in incremental-rebuild scenarios.
Before dynlink_compilerlibs/foo.mli depends on
dynlink_compilerlibs/.depend which in turn depends on all copied
source files, the present change has the impact of having the .depend
being regenerated much more often. We change its generator from
$(CAMLRUN) boot/ocamlc to $(BEST_OCAMLDEP) (using ocamlc.opt
when available); on my machine, when ocamlc.opt is available, the
.depend step goes from 0.6s to 0.2s.
Before this commit, the Makefile for compilerlibs archives only tracks
their dependencies on implementation object files (.cmo,
.cmx). .mli-only files in those directories result in a .cmi without
a .cmo.
The main makefile uses dependencies on compilerlibs archives as
a proxy for all dependencies on the corresponding compiler
modules. This assumption was broken by .mli-only modules not being
dependencies on the archives.
For example, rebuilding compilerlibs archives would not refresh
file_format/cmxs_format.cmi. The following steps would lead to a build
failure:
make core
make ocamltools
<add a new blank line at the beginning of utils/misc.mli>
make ocamltools
File "/home/gasche/Prog/ocaml/github-trunk/tools/objinfo.ml", line 1:
Error: The files /home/gasche/Prog/ocaml/github-trunk/utils/misc.cmi

make inconsistent assumptions over interface Misc
The previous promised limit of ocamlyacc was 256 entry points, but
on some platforms (x86 at least) the actual limit was 127 due to representation of
bucket->entry as char. Switching to unsigned char extends the limit to 255.
I introduced a constant MAX_ENTRY_POINT as a synonym of MAXCHAR to
handle checks against the limit consistently over the different modules
of ocamlyacc.
Extensions beyond 255 entry points would require a bit more work (which
looks unrewarding) since entry points are currently identified by a single byte
at the beginning of the input stream.
Fixes: #9207
The logic in this patch is wrong:
- setting the margins is not the responsibility of the color-handling code
- because setup_colors is called at inpredictable times (on the first error/warning),
the logic makes it very difficult to correctly set margins for `{str,err}_formatter`
The patch was originally proposed in the caml-list discussion
https://sympa.inria.fr/sympa/arc/caml-list/2015-09/msg00164.html
but it does not convincingly solve the problem:
- there is no reason to use `std_formatter`
rather than `err_formatter` as a reference, and
- the user can set the both margins themselves anyway.
In particular, since the 4.08 changes to error/warning
representations, we don't use intermediary formatters anymore to
produce error/warning messages, so setting `Formatter.std_formatter`
directly works as expected *when* this formatter is used to print to
the toplevel (the current default, which may change in the future).
Note: We have an API in `Location` to access and configure
error/warning formatters, but it is not accessible from the
toplevel. Changing the margins without using this API is fragile.
For example, utop and expect-tests change the formatter away from the
default.
The user can register several callbacks, which are called for various
events during the block's lifetime. We need to maintain a data
structure for tracked blocks in the runtime. When using threads,
callbacks can be called concurrently in a reentrant way, so the
functions manipulating this data structure need to be reentrant.
This commit modifies objinfo_helper so that the caml_plugin_header
symbol is also looked up in the static symbol table, if it is
not found in the dynamic one.
This is useful e.g. on Windows where the symbol can not be found
without this commit.
It is also necessary to look for the _-prefixed version of the symbol.
When passed an object file that comes from a different OCaml version,
objinfo will currently just detect that the magic number is not what
it expects, and claim it is not a valid file. This is irritating.
The error message output by objinfo now looks like this:
File /home/gasche/.opam/4.08.0/lib/astring/astring.cmi
Wrong magic number:
this tool only supports object files produced by compiler version
4.11.0+dev0-2019-10-18
This seems to be a compiled interface file (cmi) for an older version of OCaml.
This module was originally inspired by js_of_ocaml Misc.MagicNumber module
https://github.com/ocsigen/js_of_ocaml/blob/151b811/compiler/util.cppo.ml#L277-L347
It provides parsing and validation function for magic numbers, that
can tell the difference between "not a valid magic number" and "a
valid magic number, but with another version", and print user-friendly
user messages about it.
It does not contain any knowledge for where to find the magic number
in an OCaml file (this depends on the file format); the parsing
function should be called with an input channel already at the right
position for whichever format is expect.
Prefix may be passed to configure using a Cygwin-style PATH (e.g.
`./configure --prefix ~/local`). Use cygpath to ensure that the correct
version gets written to Makefile.config, or the resulting compiler has
an invalid default stdlib path.
Before, `man Map` would show:
```
For instance: module IntPairs = struct type t = int * int let compare (x0,y0) (x1,y1) = match Stdlib.compare x0 x1 with 0 -> Stdlib.compare y0 y1 |
c -> c end module PairsMap = Map.Make(IntPairs) let m = PairsMap.(empty |> add (0,1) hello |> add (1,0) world )
```
Now it shows:
```
For instance:
module IntPairs =
struct
type t = int * int
let compare (x0,y0) (x1,y1) =
match Stdlib.compare x0 x1 with
0 -> Stdlib.compare y0 y1
| c -> c
end
module PairsMap = Map.Make(IntPairs)
let m = PairsMap.(empty |> add (0,1) "hello" |> add (1,0) "world")
```
(in both cases the code is in bold)
Example:
module Test : sig
exception Foo
end = struct
end
Before this PR:
Modules do not match: sig end is not included in sig exception Foo end
The extension constructor `Foo' is required but not provided
After this PR (second line changed):
Modules do not match: sig end is not included in sig exception Foo end
The exception `Foo' is required but not provided
Currently Fun.protect and Misc.try_finally can be used in code that
tries carefully to preserve the first-failure backtrace, but
Misc.protect_refs cannot. This PR fixes the discrepancy. See #9057 for
a use-case.
See the GPR ( https://github.com/ocaml/ocaml/pull/9060 ) for an
in-depth discussion of the potential performance impact of this
change.
The show directive now has some basic facility to show
useful information for constructors of "normal" values,
exceptions and other non-exception extension constructors.
Also updated show_type to print out recursion status
with a default of Trec_first.
There is a small, desirable change of behavior in this PR:
we do not backtrack on all wildcard pattern explosions,
only on those where ppat_of_type knows there will be GADTs.
As a result, some exhaustivity counter-examples
have been improved with more cases (see testsuite for an example).
Value patterns match on a value (the result of computation), while
computation patterns handle the effects (hint hint) of
a computation. The only forms of computation patterns in OCaml today
are value patterns and exception patterns (exception p).
The sub-pattern `p` of the `lazy p` construction should be
a computation pattern, rather than a value pattern. This pull-request
does not make this change.
Most of the changes in this PR are boilerplate -- it really is a lot
of work now to add a new syntactic category to the typed-tree
syntax. This boilerplate is fairly automatic and should be easy to
review.
There is a subtle part to the patch, though: the implementation of the
pattern type-checking. It now has to reconstruct the value/computation
distinction (absent from the parse-tree), and return values from two
different types. Instead of splitting the type-checker in several
functions (which risked code duplications), I choose to use a GADT to
have the same [type_pat] function return two different types depending
on the caller. This is the least invasive way to adapt this part of
the codebase, whose inherent complexity is so large (unfortunately)
that adding a GADT to the mix barely makes a difference.
ocamltest maintains a list of "subdirectories where .cmi files of
compilerlibs modules are", and uses "include ocamlcommon" to make the
content of ocamlcommon.cma available.
The present PR updates the list of subdirectories (driver/ was not
included, so Compmisc.initial_env() was unusable) and creates modifier
names (like "ocamlcommon") for all compilerlibs archives.
The issue #9050 comes (partly) from #2281 forgetting to add the
compilerlibs/ocamlmiddleend archives in the installation target. The
present patch should solve this issue once and for all, by using
a wildcard to install all archives that have been built in
compilerlibs/, instead of using a manual listing.
Compared to trunk, the following extra files are installed in
$(LIBDIR)/compilerlibs: ocamlmiddleend.{a,cma,cmxa}. There are no
other changes in the installed-files list.
Locations of inlined frames are now represented as contiguous
sequences rather than linked lists.
The frame tables now refer to debug info by 32-bit offset rather
than word-sized pointer.
