From 61e58964011f65db711fd5e9f72c6d40e76feae4 Mon Sep 17 00:00:00 2001 From: Rolf Bjarne Kvinge Date: Mon, 19 Feb 2018 20:28:04 +0100 Subject: [PATCH] [mtouch/mmp] Fix tracking of whether the static registrar should run again or not. Fixes #641. (#3534) * [tests] Improve debug spew for the RebuildTest_WithExtensions test. * [mtouch/mmp] Store/load if the dynamic registrar is removed or not into the cached link results. Store/load if the dynamic registrar is removed or not into the cached link results, so that we generate the correct main.m even if cached linker results are used. * [mtouch/mmp] The static registrar must not execute if we're loading cached results from the linker. The static registrar must not execute if we're loading cached results from the linker, because the static registrar needs information from the linker that's not restored from the cache. * [mtouch/mmp] Share Touch code. * [mtouch/mmp] Make it possible to touch inexistent files (to create them). * [mtouch/mmp] Fix tracking of whether the static registrar should run again or not. The recent changes to support optimizing away the dynamic registrar caused the Xamarin.MTouch.RebuildTest_WithExtensions test to regress. The problem ----------- * The linker now collects and stores information the static registrar needs. * This information is not restored from disk when the linker realizes that it can reload previously linked assemblies instead of executing again. * The static registrar runs again (for another reason). * The information the static registrar needs isn't available, and incorrect output follows. So fix 1: show an error if the static registrar runs when the linker loaded cached results. The exact scenario the test ran into is this: * 1st build: everything is new and everything is built. * 2nd build: contents of .exe changes, the linker runs again, the static registrar runs again, but sees that the generated output didn't change, so it doesn't write the new content to disk (this is an optimization to avoid compiling the registrar.m file again unless needed). * 3rd build: only the .exe timestamp changes, the linker sees nothing changes in the contents of the .exe and loads the previously linked assemblies from disk, the static registrar sees that the .exe's timestamp is newer than registrar.m's timestamp and run again, but doesn't produce the right result because it doesn't have the information it needs. Considered solutions -------------------- 1. Only track timestamps, not file contents. This is not ideal, since it will result in more work done: in particular for the case above, it would add a registrar.m compilation in build #2, and linker rerun + static registrar rerun + registrar.m compilation + final native link in build #3. 2. Always write the output of the static registrar, even if it hasn't changed. This is not ideal either, since it will also result in more work done: for the case above, it would add a registrar.m compilation + final native link in build #3. 3. Always write the output of the static registrar, but track if it changed or not, and if it didn't, just touch registrar.o instead of recompiling it. This only means the final native link in build #3 is added (see #5 for why this is worse than it sounds). 4. Always write the output of the static registrar, but track it it changed or not, and if it didn't, just touch registrar.o instead of recompiling it, and track that too, so that the final native link in build #3 isn't needed anymore. Unfortunately this may result in incorrect behavior, because now the msbuild tasks will detect that the executable has changed, and may run dsymutil + strip again. The executable didn't actually change, which means it would be the previously stripped executable, and thus we'd end up with an empty .dSYM because we ran dsymtil on an already stripped executable. 5. Idea #4, but write the output of the final link into a temporary directory instead of the .app, so that we could track whether we should update the executable in the .app or not. This is not optimal either, because executables can be *big* (I've seen multi-GB tvOS bitcode executables), and extra copies of such files should not be taken lightly. 6. Idea #4, but tell the MSBuild tasks that dsymutil/strip doesn't need to be rerun even if the timestamp of the executable changed. This might actually work, but now the solution's become quite complex. Implemented solution -------------------- Use stamp files to detect whether a file is up-to-date or not. In particular: * When we don't write to a file because the new contents are identical to the old contents, we now touch a .stamp file. This stamp file means "the accompanying file was determined to be up-to-date when the stamp was touched." * When checking whether a file is up-to-date, also check for the presence of a .stamp file, and if it exists, use the highest timestamp between the stamp file and the actual file. Now the test scenario becomes: * 1st build: everything is new and everything is built. * 2nd build: contents of .exe changes, the linker runs again, the static registrar runs again, but sees that the generated output didn't change, so it doesn't write the new content to disk, but it creates a registrar.m.stamp file to indicate the point in time when registrar.m was considered up-to- date. * 3rd build: only the .exe timestamp changes, the linker sees nothing changes in the contents of the .exe and loads the previously linked assemblies from disk, the static registrar sees that the .exe's timestamp is *older* than registrar.m.stamp's timestamp and doesn't run again. We only use the stamp file for source code (registrar.[m|h], main.[m|h], pinvokes.[m|h]), since using it every time has too much potential for running into other problems (for instance we should never create .stamp files inside the .app).
