* [lit] Protect full test suite from FILECHECK_OPTSJoel E. Denny2019-11-061-2/+9
| | | | | | | | | | | | | | | | | | lit's test suite calls lit multiple times for various sample test suites. `FILECHECK_OPTS` is safe for FileCheck calls in lit's test suite. It's not safe for FileCheck calls in the sample test suites, whose output affects the results of lit's test suite. Without this patch, only one such sample test suite is protected from `FILECHECK_OPTS`, and currently `shtest-shell.py` breaks with `FILECHECK_OPTS=-vv`. Moreover, it's hard to predict the future, especially false passes. Thus, this patch protects all existing and future sample test suites from `FILECHECK_OPTS` (and the deprecated `FILECHECK_DUMP_INPUT_ON_FAILURE`).

* [lit] Drop the user-site packages directory from search paths when running testsAlex Lorenz2019-10-271-0/+4
| | | | | | | Do not add user-site packages directory to the python search path. This avoids test failures if there's an incompatible lit module installed inside the user-site packages directory, as it gets prioritized over the lit from the PYTHONPATH.
* [lit] Check for accidental external command callsJoel E. Denny2019-08-191-0/+11
| | | | | | | | | | | | | | | This patch extends lit's test suite to check that lit's internal shell doesn't accidentally execute internal commands as external commands. It does so by putting fake failing versions of those commands in `PATH` while the entire lit test suite is running. Without the fixes in D65697 but with its tests, this approach catches accidental external `env` calls. Reviewed By: probinson Differential Revision: https://reviews.llvm.org/D66293 llvm-svn: 369309
* [lit] Fix 42812: lit test suite can no longer be run stand-aloneStella Stamenova2019-08-021-1/+12
| | | | | | | | | | | | | | | | | | | Summary: This change updates the lit.cfg file to use llvm_config when it is available, but when it is not, it directly modifies the config object. This makes it possible to run the lit tests standalone without having built llvm (as long as the correct binaries are present in the path such as FileCheck and not). Because the lit tests don't take a hard dependency on llvm_config, some features such as system-windows have to have definitions in lit's cfg file as well. This is a potential issue as the os features sometimes change names (for example, we went from windows to system-windows, etc.). This can cause drift between lit's tests and the rest of the llvm tests.

* [AIX][lit] Don't depend on psutil on AIXDavid Tenty2019-07-241-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: On AIX psutil can run into problems with permissions to read the process tree, which causes problems for python timeout tests which need to kill off a test and it's children. This patch adds a workaround by invoking shell via subprocess and using a platform specific option to ps to list all the descendant processes so we can kill them. We add some checks so lit can tell whether timeout tests are supported with out exposing whether we are utilizing the psutil implementation or the alternative.

This change updates the logic in the test logging for lit to correctly process each of the types, and more importantly, to not just fail in Python3. This change also reverses the use of quotes in several of the cfg files. By using '""' we are guaranteeing that the resulting path will work correctly on Windows while "''" only works correctly sometimes. This also fixes one of the failing tests.

* Relax shtest-run-at-line.pyHans Wennborg2018-06-061-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test was failing on Windows machines which had bash.exe on PATH (but not in the so called lit tools dir, containing cmp.exe, grep.exe etc.). The problem was that the outer lit invocation would load LLVMConfig from utils/lit/lit/llvm/config.py, which looks up the tools path with getToolsPath(). That has a surprising side effect of also setting bashPath, in our case setting it to empty. The outer lit invocation would thus configure the pdbg0 and pdbg1 substitutions based on not running with bash. But the inner lit invocation would not load LLVMConfig, so bash would be found on PATH, that would be used as external shell, and so the output wouldn't match pdbg0 and pdbg1. It seems weird to me that getBashPath() will return different results depending on whether getToolsPath() has been called before, but I also don't know how to fix it properly. This commit just relaxes the test case, because there doesn't seem to be much point in testing for the exact syntax of the run file as long as it works.

* Resubmit "[lit] Force site configs to run before source-tree configs"Zachary Turner2017-09-151-3/+2
| | | | | | | | | | | | | | | | | | | | This is a resubmission of r313270. It broke standalone builds of compiler-rt because we were not correctly generating the llvm-lit script in the standalone build directory. The fixes incorporated here attempt to find llvm/utils/llvm-lit from the source tree returned by llvm-config. If present, it will generate llvm-lit into the output directory. Regardless, the user can specify -DLLVM_EXTERNAL_LIT to point to a specific lit.py on their file system. This supports the use case of someone installing lit via a package manager. If it cannot find a source tree, and -DLLVM_EXTERNAL_LIT is either unspecified or invalid, then we print a warning that tests will not be able to run.

* [lit] Force site configs to be run before source-tree configsZachary Turner2017-09-141-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch simplifies LLVM's lit infrastructure by enforcing an ordering that a site config is always run before a source-tree config. A significant amount of the complexity from lit config files arises from the fact that inside of a source-tree config file, we don't yet know if the site config has been run. However it is *always* required to run a site config first, because it passes various variables down through CMake that the main config depends on. As a result, every config file has to do a bunch of magic to try to reverse-engineer the location of the site config file if they detect (heuristically) that the site config file has not yet been run. This patch solves the problem by emitting a mapping from source tree config file to binary tree site config file in llvm-lit.py. Then, during discovery when we find a config file, we check to see if we have a target mapping for it, and if so we use that instead. This mechanism is generic enough that it does not affect external users of lit. They will just not have a config mapping defined, and everything will work as normal. On the other hand, for us it allows us to make many simplifications: * We are guaranteed that a site config will be executed first * Inside of a main config, we no longer have to assume that attributes might not be present and use getattr everywhere. * We no longer have to pass parameters such as --param llvm_site_config=<path> on the command line. * It is future-proof, meaning you don't have to edit llvm-lit.in to add support for new projects. * All of the duplicated logic of trying various fallback mechanisms of finding a site config from the main config are now gone. One potentially noteworthy thing that was required to implement this change is that whereas the ninja check targets previously used the first method to spawn lit, they now use the second. In particular, you can no longer run lit.py against the source tree while specifying the various `foo_site_config=<path>` parameters. Instead, you need to run llvm-lit.py.

* [lit] Implement support of per test timeout in lit.Dan Liew2015-12-271-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should work with ShTest (executed externally or internally) and GTest test formats. To set the timeout a new option ``--timeout=`` has been added which specifies the maximum run time of an individual test in seconds. By default this 0 which causes no timeout to be enforced. The timeout can also be set from a lit configuration file by modifying the ``lit_config.maxIndividualTestTime`` property. To implement a timeout we now require the psutil Python module if a timeout is requested. This dependency is confined to the newly added ``lit.util.killProcessAndChildren()``. A note has been added into the TODO document describing how we can remove the dependency on the ``pustil`` module in the future. It would be nice to remove this immediately but that is a lot more work and Daniel Dunbar believes it is better that we get a working implementation first and then improve it. To avoid breaking the existing behaviour the psutil module will not be imported if no timeout is requested. The included testcases are derived from test cases provided by Jonathan Roelofs which were in an previous attempt to add a per test timeout to lit (http://reviews.llvm.org/D6584). Thanks Jonathan!
