This reverts commit 0cdfa69f216854d7319a6a31a61021a1e5ac45de.
We need to hide json includes: modules cannot cope with them, and it introduces a runtime requirement to find json.
`RunFunction()` might trigger unloading of `lastT`, so store its setting
for "want value printing" in a local variable before calling RunFunction().
Fixes valgrind complaining about `./stressInterpreter` which is reloading
the "outer" stressInterpreter.cxx from inside `RunFunction()`.
When determining whether a weak symbol was already emitted (and its
subsequent definition can thus be replaced by a declaration) look
for emitted symbols in the symbol table and the in-process symbols,
instead of possibly generating symbols through the JIT. This prevents
symbols being emitted that refer into
IncrementalExecutor::m_PendingModules elements that have since been
removed.
The case of `ExprAddresses == nullptr` seems to be naturally handled in the
lines below. Therefore, removing this assertion -as discussed with vvassilev.
Closes issue #8389.
This is now hit for variables on Windows (which don't see the GlobalVariable case).
Before the `#ifndef WIN32`, this case was not hit by roottest, neither on Windows
nor macOS nor Linux - so the coverage of "make it a declaration" is good.
Fixes test failures (crashes) in
projectroot.test.test_stressiterators_interpreted
projectroot.roottest.cling.dict.roottest_cling_dict_assertTmpltDefArgCtor
projectroot.test.test_stresshistogram_interpreted
projectroot.roottest.root.meta.roottest_root_meta_runnamespace_auto
Instead of suppressing the emission of weak symbols that have an existing
in-process definition, remove the definition of the weak symbol from the
module. This prevents relocation "surprises" as seen e.g. on Apple M1, where
weak symbol definitions are expected to be found within the module, and
relocations are thus expected to be local. By removing the definition, the
symbol becomes a reference (declaration) and relocation will work as for any
non-local symbol.
Thus also reduces the amount of duplicate work, as in-process weak symbols
will now be suppressed early.
* [cling][windows] change compiler flags
- Set the `-std:c++14` / `-std:c++17` flag depending on the version of Visual Studio (only if building outside ROOT)
- Split the one line exports in three lines to fix a potential issue with Ninja on Windows (missing a white space between each `/EXPORT:` specifier)
* Add a forgotten `endif()`
These changes enable the replacement of the default DiagnosticConsumer provided
by CIFactory. Concretely, two member functions have been added to the
Interpreter class:
- replaceDiagnosticConsumer(): replaces the default CIFactory-provided DiagnosticConsumer.
- hasReplacedDiagnosticConsumer(): returns whether the default diagnostic
consumer has been replaced.
Replace implementation of `InputValidator::validate()` by simpler, more
maintainable code that also fixes ROOT-9202.
The previous implementation was unable to properly handle line continuation
after ',' or '\'. Specifically, it skipped over non-punctuation tokens,
entering continuation mode even if ',' or '\' were not the last tokens in the
input, e.g. `int a, b` or 'int a \ b'.
Fixes ROOT-9202.
This commit includes the following changes to MetaLexer:
- Update `MetaLexer::Lex()` to return `/*` (tok::l_comment), `*/` (tok::r_comment),
and `<` (tok::less) as tokens.
- Added `MetaLexer::ReadToEndOfLine()` function: consume input until `\r` or `\n`.
- Added `MetaLexer::RAII`, a RAII object that saves/restores the current position.
This new release includes some improvements:
* Extended array support
* Add cmake variables to control the locations where find_package discovers LLVM and Clang: `LLVM_CONFIG_EXTRA_PATH_HINTS` and `Clang_CONFIG_EXTRA_PATH_HINTS` respectively.

Some libraries are layered can depend on other libraries on a private paths.
That is, libA can depend on libB which is neither on the LD_LIBRARY_PATH nor
on a known system path. The posix linker injects "variables" such as @rpath
which is expanded at link time to resolve the libraries on a relative path.
Prior to this patch, cling's Dyld-based symbol resolution could not trace down
such cases causing failures in symbol resolution when a symbol is only defined
in libB (a private library).
This patch implements the basic posix linker substitutions allowing cling's
Dyld-based symbol resolution implementation to follow more closely the linker
rules.
Kudos Alexander Penev (@alexander-penev).
This regression was introduced by root-project/root@561e905b where we stopped
iterating, on every lookup, over the -L paths passed at start up.
This patch adds the path to the search paths of the DynamicLibraryManager
rather than to the invocation options.
* Update minimal CMake version in favour of advances features it offers
* Remove workaround for FindDoxygen (cmake < 3.13)
* Remnove workaround for cmake < 3.14 to able to report issue directly to stdout
* Remove workaround for CMake < 3.14 when Ninja 1.9.0 builds static libraries twice
* Remove other CMake hack from multi-python ROOT builds
* We are using 3.16 as a min CMake version and REGEX is definitely available in this version
* Remove code used to search Python2/Python3 with <= CMake 3.14
* [cmake] check for internet connection. Fixes#8292
This should fix an issue with external packages requiring an internet connection when working offline.
If there is no internet connection, they are either automatically disabled or raise a `FATAL_ERROR` if the `fail-on-missing` flag is `ON`
* Add forgotten "is" (thanks @pamputt)
* Add internet check for the forgotten 'davix' and 'ssl' options
* Change the timeout value and add information messages (thanks Axel)
* Let's download an existing file to test internet access
* Disable also clad if there is no internet connection
* Do not add the clad directory in case of no internet access
* Change the logic for clad with no internet connection
* disable clad early enough if there is no internet connection
* Disable also xrootd when disabling builtin_xrootd
Disable the silly workaround for cling not being able to parse the STL headers anymore after the update of Visual Studio v16.7.0. Works now with the upgrade of LLVM and Visual Studio 16.10.3.
This workaround had side effects when trying to use code supporting CUDA (e.g. boost) inside the interpreter.
Warn on redundant parentheses in declarators whose parsing might not match
the user intent, e.g.
```
root [0] int i = 1;
root [1] (bool)i
(bool) true
root [2] bool(i)
ROOT_prompt_1:1:5: warning: redundant parentheses surrounding declarator [-Wredundant-parens]
bool(i)
^~~
(bool) false
```

Closes issue #8304.
Before, only the using decl itself was forward declared, causing
undeclared identifiers in forward declaration code, as witnessed in
https://github.com/root-project/root/issues/8499
Given the similarity of using and typedef, merge both into a single
function, making sure both have the same featureset, and through that
fixing this issue as a side-effect.
Rather than string-replacing visibility, use the CMake interface.
Do not set visibility in the ROOT case; ROOT can handle that
just fine itself.
ROOT actually does *not* need visibility=default, now that the
few symbols that are required for using cling (apart from clingtest)
are explicitly requested through attributes.
and use a standard mechanism that plays well with -fvisibility.
Given that several symbols now use declspec(dllexport), remove them from
the ad-hoc cling_exports in ROOT's CMakeLists.txt.
Additionally, this commit extends the behavior of `.x`. Specifically, it adds
support for a list of function names whose execution will be tried in order.
To be compliant with the old behavior, this list currently only includes an
entry that matches the macro filename.
The dynamic library manager's dyld can search a symbol in the library path.
This patch uses that functionality to aid the 'unresolved while linking'
diagnostics.
Now we get:
cling -L lib/
****************** CLING ******************
* Type C++ code and press enter to run it *
* Type .q to exit *
*******************************************
[cling]$ extern int gErrorIgnoreLevel;
[cling]$ gErrorIgnoreLevel
IncrementalExecutor::executeFunction: symbol 'gErrorIgnoreLevel' unresolved while linking [cling interface function]!
Symbol found in '/.../lib/libCore.so'; did you mean to load it with .L /.../lib/libCore.so ?
[cling]$
This avoids problems where we consider other executables and object files as
libraries and the dyld decides to scan them. Upon this we hit files opened by
other processes and locked by the system (such as bootstat.dat :))
Thanks to Bertrand Bellenot for the diagnosis!
