* catchable defects (#13626)Andreas Rumpf2020-03-121-1/+1
| | | | | | | | | | * allow defects to be caught even for --exceptions:goto (WIP) * implemented the new --panics:on|off switch; refs https://github.com/nim-lang/RFCs/issues/180 * new implementation for integer overflow checking * produce a warning if a user-defined exception type inherits from Exception directly * applied Timothee's suggestions; improved the documentation and replace the term 'checked runtime check' by 'panic' * fixes #13627 * don't inherit from Exception directly

* Initial version of the hot-code reloading support for native targets (#10729)zah2019-02-261-4/+4

Also typeinfo globals are registered (created) in a single pass before the DatInit pass (because of the way generic instantiations are handled) Fix the test suite execution on macOs fix for being able to query the program arguments when using HCR on posix! other fixes * Bugfix: Fix a compilation error in C++ mode when a function pointer is converted to a raw pointer * basic documentation for the new hot code reloading semantics * Add change log entry * Don't re-execute the top-level statements while reloading JS code * fix a number of tests broken in a recent bugfix * Review changes * Added {.executeOnReload.} pragma that indicates top-level statements that should be executed on each reload. To make this work, I've modified the way the `if (hcr_init_) {...}` guards are produced in the init code. This still needs more work as the new guards seem to be inserted within the previously generated guards. This change also removes the need for `lastRegistedGlobal` in nimhcr. * Implemented the `signatureHash` magic and the `hasModuleChanged` API depending on it (the actual logic is not imlemented yet). * Add the "hcr" prefix to all HCR-related symbols in the system module. Added a new `hotcodereloading` module exporting the high-level API to the user. Besides being more hygienic, this was also required in order to make it possible to use macros in the high-level API. Without the split, `system` would have to import `macros`, which was going to produce the well-known init problems. * Attempted to solve the "GC markers problem". Crashes were expected with the previous code, because the GC markers were compiled as normal procs are registered in the GC. When their module is unloaded, dangling pointers will remain in the GC tables. To solve this issue, I don't register any GC markers when HCR is on, but I add them to the HCR globals metadata and I use a single marker registed in nimhcr during the initialization of the system module that will be responsible for marking all globals. * fix a compilation error * - implemented the hasModuleChanged functionality - tuples can be returned and broken into different vars in global scope - added comments for the closnig scopes of the if statements in the init proc - the new executeOnReload pragma works now! - other fixes * finally! fixing this hack in a proper way - declaring the destructor out of line (out of the class body) - we no longer need to forward-declare popCurrentExceptionEx * Force full module parsing This is a temporary hack that breaks some tests. I'll investigate later how these can be fixed. * tuples are now properly handled when global! * these comments mess up the codegen in debug mode when $n is not actually a new line (or something like that) - these labels are intended only for GOTO labels anyway... * "solved" the issue with the .pdb locks on windows when a binary is being debugged and hot code reloading is used at the same time * fixes after rebasing... * small fixes for the test * better handling of globals! no more compiler crashes for locals with the global pragma, also simplified code around loops in global scope which have local vars (actually globals) * we can now use the global pragma even for ... globals! * the right output * lets try those boehm GC tests * after the test is ran it will be at its starting state - no git modifications * clarification in the docs * removed unnecessary line directives for forward declarations of functions - they were causing trouble with hot code reloading when no semantic change propagates to the main module but a line directive got changed and thus the main module had to be recompiled since the .c code had changed * fixed bug! was inserting duplicate keys into the table and later was removing only 1 copy of all the duplicates (after a few reloads) * no longer breaking into DatInit code when not supposed to * fixes after rebasing * yet more fixes after rebasing * Update jssys.nim * Rework the HCR path-handling logic After reviewing the code more carefully, I've noticed that the old logic will be broken when the user overrides the '--out:f' compiler option. Besides fixing this issues, I took the opportunity to implement the missing '--outdir:d' option. Other changes: * ./koch test won't overwrite any HCR and RTL builds located in nim/lib * HCR and RTL are compiled with --threads:on by default * Clean up the globals registration logic * Handle non-flattened top-level stmtlists in JS as well * The HCR is not supported with the Boehm GC yet Also fixes some typos and the expected output of the HCR integration test * The GC marker procs are now properly used as trampolines * Fix the HCR integration test in release builds * Fix ./koch tools * this forward declaration doesn't seem to be necessary, and in fact breaks HCR because a 2nd function pointer is emitted for this externed/rtl func * the forward declaration I removed in the last commit was actually necessary * Attempt to make all tests green * Fix tgenscript * BAT file for running the HCR integration test on Windows [skip ci] * Fix the docgen tests * A final fix for Travis (hopefully)
