* add package to generated Build in build.scala and in-package discoveryChristopher Vogt2017-02-151-23/+31
| | | | | | | | | | | This should allow for build to add other builds to their dependencies and interact with them in a type-safe way. And ever regardless it seems like good practice to never have the same class existing in the same package or the top-level package even if they don’t end up on the same classpath. This might also help make stack traces easier to understand. Also improve error messages for mistakes with the build class, e.g. constructor, super classes, etc.
* now really cache classloaders for buildsChristopher Vogt2017-02-141-7/+3

* idempotent change propagationChristopher Vogt2017-02-091-38/+43
| | | | | | using lastModified instead of a non-idempotent needsUpdate flag this fixes a bug where dependees would not be rebuilt if cbt exited or was killed after dependencies were already rebuilt.
* memoize task results across classes within a single runChristopher Vogt2017-02-091-1/+24

* make full dependencies available to compile instead of only classpathChristopher Vogt2017-02-011-1/+2
| | | | | this will make it possible to access lastModified times and cache them in the following commits
* replace flawed concurrent hashmap cache with consistent replacementChristopher Vogt2017-02-011-1/+0
| | | | | | | | | | | | | | | | | | | | | | | The concurrent hashmap approach to classloader caching was flawed. Assume you have two concurrently running builds A and B and projects P2 and P3 depending on project P1. And assume a time sequence where A compiles P1, then compiles P2, then P1’s sources change, then B compiles P1, then A compiles P3. At the end P2 and P3 will have different versions of P1 as their parent classloaders. This is inconsistent. The easiest way to work around this is making sure only one thread is changing the classloader cache during it’s entire run. This would mean either no concurrency or what we have done here, which is letting threads work on a copy of the cache and replace the original cache in the end using an atomic operation. This means the thread that finishes last wins, but for caching that’s fine. Worst case some things aren’t cached in a concurrent execution. This change also means that we don’t need concurrent hashmaps for the classloader cache anymore since no two theads will access the same hashmap. We still need a concurrent hashmap for the class caches inside of the classloaders as multiple threads can access the same classloaders.
* Merge separate hashmaps for persistent cache into oneChristopher Vogt2017-02-011-5/+8
| | | | | | | This isn’t type-safe, but re-using that same hashmap for both keys and classloaders allows to reduce the number of members in Context. Also we can re-use the same hashMap for other things as well in the coming commits, e.g. timestamps.
* swap out System.out and System.err in a way that affects JDK and ScalaChristopher Vogt2016-10-131-6/+29
| | | | | | | | Before it only affected jdk, because scala.Console captures our and err before the swap. This is needed when running main classes like Scaladoc or the compiler and wanting to redirect output to standard error
* do not interpret exceptions during redirectOutToErr as scalac crashesChristopher Vogt2016-10-131-22/+22
|
* Fix exit code trapping across classloadersChristopher Vogt2016-10-071-4/+4
| | | | | | | | | | A SecurityManager is once installed globally and stays the same across all classloaders. TrapSecurityManager was installed this way, but it looked up the `trapExitCode` in it's own classloader, while classes in other classloaders (when cbt was using another version of cbt) were writing it to their own classloader. This flag needs to be in a global place instead to fix this, so we'll put it straight into the TrapSecurityManager itself.

* fix checksum check for downloaded jars by ignoring caseChristopher Vogt2016-09-151-3/+3
|
* fix behavior of System.exit trappingChristopher Vogt2016-09-151-2/+4
| | | | | | | | | Installing one globally for the JVM live-time and make behavior dependent on a thread local variable seems safer than globally switching it out and having race conditions. Also now all other calls are forwarded to a potential Nailgun SecurityManager, which should fix some bugs.
* Support proxy settings in CBT.Benjamin Frank2016-07-061-1/+1
| | | | | | | Proxy settings can be supplied either via Java system-properties or via environment variables (http_proxy/https_proxy/no_proxy). Java system-properties take precedence over env vars. Evaluation of proxy settings happens only during nailgun startup for now.

* Reproducible builds, composing different CBT version and various improvementsChristopher Vogt2016-04-281-20/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One large commit, because it is was hard to do these things in isolation or to separate them now. CBT now knows how to load other versions of itself - Support for reproducible builds (!), by providing a CBT git URL and hash to tie build to - Support for composing builds using different CBT versions (!) - introduce (in compatibility/) Java interfaces all CBT versions need to stay compatible with, so they can talk to each other. And put extension methods to these interfaces in cbt package object Class loading - add some sanity checks for class loading - improve class loader invalidation to fix bugs - implement caching in Java land class loaders. In particular to prevent the system class loader to repeatedly generate ClassNotFound exceptions in each sink of the class loader DAG for non JDK classes (meaning major speed up for projects with many classes). - getting rid of transient class loader cache unifying into "persistent" one instead (which is still wrong as invalidation eventually needs to invalidate entire sub graphs of the class loading DAG, not single class loaders. Seems like we'll have to abandon the hashmap based approach and tie caching to dependency objects) Other Caching - cache dependencies extracted from xml files, which was one major time killer, but invalidate cache when cbt changed (maven dependency user facing api needs simplification now!) - memorize last successful compile time in the file system rather than memory, to guard against unnecessary recompiling even across launches (or when using cbt direct) Structural improvements - Factor out ClassLoaderCache on Java land into its own class. - Port MultiClassLoader to Java land, to better compose classloaders in NailgunLauncher. - Remove many global constants and variables (in object paths and in NailgunLauncher) and pass them through instead. Needed for composing of builds. - move more code from resolver into Lib for less entanglement with classes (needed to compatibility interfaces) and better re-usability - remove canBeCached. Everything can be cached now, but we need to be careful about correct invalidation. - remove build announcing produced jars. We can add if ever needed. - change callNullary to return exit code instead of Unit as preparation for next commit introducing "recursive" ScalaTest - Makes ScalaTest support work (still a bit too inflexible, but mostly works well)

* Correctly interact with build in cwd instead of loading it's managed build ↵Christopher Vogt2016-04-061-1/+1

* Implement alternative resolversChristopher Vogt2016-04-031-26/+49
| | | | | | | | | | | | This commit also - requires Dependencies to explicitly implement canBeCached - unifies some logic for dependency downloading - moves SBT-like dependency DSL into its own trait - error message showing build directory for exceptions in builds Not splitting this up in favor of faster progress to 1.0. The user facing API can probably be slightly improved using implicits inside of BasicBuild, but we can do that later.
* propagate info if cbt has changed across builds, so they can be re-compiledChristopher Vogt2016-04-021-1/+1

* only compile and only produce jars if there are actually files.Christopher Vogt2016-04-021-51/+53
| | | | This seem desirable, but also fixes a test failure for which I have no idea why it didn't fail before but now.
* Makes zinc usage smarter, so we do not need to call it when no files changed ↵Christopher Vogt2016-03-301-16/+23
| | | | | | (and safe up to 0.1s for each call) There still seem to be 2 bugs related to CBT development in the code. One if you simpy save a stage1 file unchanged and re-run cbt, it fails to call Stage2.run reflectively. Also in case of compile errors in stage1, a TrappedExitCode exception is thrown and not caught.
* replace Scala reflection with Java reflection seems to fix the weird ↵Christopher Vogt2016-03-281-16/+0
| | | | exceptions that happened in the previous commit. Also gets rid of scala.reflect dependency in stage2.
* Early classloading improvementsChristopher Vogt2016-03-281-23/+5
| | | | | | | | | - Changed launcher to already load zinc - use code generation to generate necessary dependencies - changed resolver to linearize dependency DAG in a way that guarantees that every transitive dependee of a node in the DAG is a transitive dependee of that node in the linear sequence - move exit code trapping code into java so it can be used for zinc early There seems to be a bug in this version, where CBT crashes about half of the time with a "object is not an instance of declaring class" Exception during running the task from the build object via reflection.

| | | | | | replace two level classloader (one for non-cachable dependencies with a cached parent one for cachable ones) with a hierachy of classloaders corresponding this should eventually allow re-using CBT's classloader between stage1 and stage2 this change breaks the ScalaTest support for now
