* make `-w dupbuild` default to `err`Nico Weber2018-04-051-0/+1
| | | | | | | | | You can still opt out of this by passing `-w dupbuild=warn`. But if you're getting this diagnostic, your build files are incorrect and you should ideally just fix them. This is step 3 on https://github.com/ninja-build/ninja/issues/931 I sent an RfC to ninja-build a few months ago; nobody objected.

* [compdb] Expand response files inline based on a switch.Asanka Herath2018-04-051-2/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | References to response files in a clang compile_commands.json file can be tricky to deal with when tooling expects all the command flags to be present in the 'command' field. This change introduces a '-x' option to '-t compdb' that will expand @rspfile style response file invocations inline. E.g. ```sh $ ninja -t compdb cc [ { "directory": "/src/foo", "command": "cc -foo -bar @foo.obj.rsp", "file": "foo.cc" } ] $ ninja -t compdb -x cc [ { "directory": "/src/foo", "command": "cc -foo -bar foo.cc", "file": "foo.cc" } ] ```

| | | | | | | | | | | | Destruction of NinjaMain can be an expensive operation when dealing with stupidly large ninjafiles. exit directly instead of returning out of real_main to avoid doing so.

* Restore tolerance of self-referencing phony build statementsBrad King2017-09-081-2/+16
| | | | | | | | | | | | | | | | | | | | Since commit v1.8.0^2~3^2~1 (Teach RecomputeDirty to detect cycles in the build graph, 2015-11-13) we correctly reject self-referencing phony build statements like build a: phony a as cycles. Unfortunately this breaks support for CMake 2.8.12.x and 3.0.x because those versions incorrectly produce edges of this form (that we used to tolerate). In order to preserve compatibility with those CMake versions we need to restore tolerance of these edges. Add a special case to the manifest parser to filter out self-referencing inputs of phony edges of the form produced by those CMake versions. Warn by default, but add a `-w phonycycle={err,warn}` option to make it an error. Fixes: #1322
* Factor ManifestParser options into a structureBrad King2017-09-071-4/+5
| | | | | | This will allow more options to be added without updating everywhere that constructs a ManifestParser. Also extend the AssertParse function to take the options so tests can control them.
* Support restat when rebuilding manifestDan Willemsen2017-02-081-4/+13
| | | | | | | | As a fix for #874, we started reloading the entire manifest even if the manifest was never rebuilt due to a restat rule. But this can be slow, so call State::Reset instead, which also fixes the original crash. Fixes #987

| | | | | | | Add --port option to override the default port (8000). Add --no-browser option to avoid opening a web browser (useful over SSH). Make the target name optional, using "all" if omitted.
* Fix ambiguous call to set_terminate on Windows platformg4m42016-02-171-1/+1
| | | | | | | On Windows set_terminate() could either be the standard C++ one or (actually the same one but in the global namespace) the CRT one declared in corecrt_terminate.h Hence this ambiguity - this patch solves it. Signed-off-by: g4m4 <misept.dieseneuf@gmail.com>

* Let Stat() have an err outparam instead of writing to stderr.Nico Weber2015-03-311-2/+11
| | | | | | | | | Also check for Stat() failure in a few more places. This way, ninja doesn't print two "ninja: error: " lines if stat() fails during a build. It also makes it easier to keep the stat tests quiet. Every caller of Stat() needs to explicitly log the error string if that's desired.
* Add an opt-in flag to make duplicate edges an error (`-w dupbuild=err`).Nico Weber2015-03-241-3/+38

| | | | | | | | | Ninja generators that bootstrap themselves with Ninja may need to rebuild build.ninja multiple times. Replace the 2 cycle loop with a 100 cycle loop, and print the pass number each time it restarts. Original-author: Jamie Gennis <jgennis@gmail.com>
* Revert #223, fixes #874.Nico Weber2014-12-041-5/+4
| | | | | | | | No test since there's still no good way to test code in ninja.cc. Going forward, either move NinjaMain to its own file with tests, or create a system that makes it possible to run integration tests on the ninja binary. Instead, add a comment that explains why the restat optimization isn't done.

* Make sure configure.py and ninja.cc always agree on if -t browse is included.Nico Weber2014-11-141-2/+2
| | | | | | | | | No behavior change on most platforms. On solaris, -t browse was compiled in in ninja.cc but browse.cc wasn't compiled in, which probably means that building on Solaris didn't work. It might be better now. This also makes browse.cc automatically not included in bootstrap builds; previously this was done manually through the NINJA_BOOTSTRAP check.

| | | | | | | | | | | | | | | | | | | | This brings the flag more inline with its description: "change to DIR before doing anything else". The use case is to make it possible to use -C together with -t msvc. When debugging Windows builds, it's handy to be able to copy-paste the commands from "ninja -v" and make them run in the correct directory by adding this flag.

| | | | | | | | | | | | | | | | | | | | | | This is to keep the possibility of maybe having a tool that deletes old files in the future, or for having a tool which exposes this information to generators so they can do that.
