Strictly define the expected behavior of filesystem APIs and write tests to verify compliance

      Description

      FileSystem and FileContract aren't tested rigorously enough -while HDFS gets tested downstream, other filesystems, such as blobstore bindings, don't.

      The only tests that are common are those of FileSystemContractTestBase, which HADOOP-9258 shows is incomplete.

      I propose

      1. writing more tests which clarify expected behavior
      2. testing operations in the interface being in their own JUnit4 test classes, instead of one big test suite.
      3. Having each FS declare via a properties file what behaviors they offer, such as atomic-rename, atomic-delete, umask, immediate-consistency -test methods can downgrade to skipped test cases if a feature is missing.

          Juan: thanks for the testing. The entire Swift test suite is skipped if there's no auth-keys file -though we could migrate that to the contract-test-options.xml file. The reason for that policy is that

          1. some of the junit 3 test suites that are subclassed for hadoop-common-test aren't skippable (junit 3, see) -this is why in Hadoop common the s3 & ftp tests don't start with Test*. While the contract tests are designed to be self-skipping -and so logged in test reports, I left the junit 3 stuff with a Test profile -you can't really test the swift client without the settings, except for some minor unit tests

          Jay: tighter exceptions provide more information to clients, and lets you explicitly catch by type in your code, e.g. catch(EOFException e. general IOExceptions with text have to be caught as IOE and then tested -and are incredibly brittle to changes in text. That's why I didn't rename text messages from exceptions in the common filesystems, even when I tightened their class: we don't know what callers are searching for the text.

          Whenever you can, use explicit types. I also recommend using constants for text, constants that tests can look for -and in those tests use Exception.toString().contains() as the check -not equality, so that if more details are added the test still works.

          I have a minor question - finally had time to look at the patch again.

          What is the policy on using java.io exceptions with Fs. exception messages (i.e. as in {{ STREAM_IS_CLOSED }} ) versus more specific ones ?

          Tested two swift provider, Rackspace and HP Cloud. everything works fine. I am a little bit confused by the openstack config file. I thought with this new contract-test-options.xml, I don't need other configuration. Turn out I still need to create the auth-keys.xml and put swift service name there.

          I re-tested latest patch with S3N and Swift, test files are cleaned up. All looks good, thanks Steve.

          One trivial thing is one file is left after tests are done. testRmNonEmptyRootDirNonRecursive

          I understand the purpose of this test is to verify the directory cannot be deleted if it's not empty.
          But it would be nice to have some cleanup function to cleanup all files/dirs created during tests since we use the real cloud service.

          will fix

          In testing.md, the config file path should be "hadoop-common-project/hadoop-common/src/test/resources/contract-test-options.xml", not "hadoop-common-project/hadoop-common/src/test/contract-test-options.xml".

          Okay, I can see the value in that. Maybe there's some creative way to de-dupe some of the repeated @BeforeClass and @AfterClass type stuff, but it seems hard given the lack of multiple inheritance. I like your naming proposals (tests and the xml).

          I'll try to fire up some of these different cloud offerings in the meantime. I guess it'd be good for at least one other person to go through the exercise of running them.

          that was a bit oddly formatted, text editor wraps vs JIRA ones.

          I was trying to say in having separate tests/feature is that you can work on a feature at a time, rather than run the subclass of FileSystemContractBaseTest you have today, which take long enough to make a decent coffee or, in the case of object stores, walk to a nearby cafe and back

          Validating S3/Swift tests.

          It's still hard for me to run the S3 / Swift tests since I'd have to get credentials,

          These tests cost ~$0 to run as they don't persist data; you can use your own private
          logins. I'd recommend >1 swift provider (I use RAX US, RAX UK and HP Cloud for their different
          auth, consistency and throttling). S3 has different consistency models for US-east (worst) and
          everywhere else. You need to create buckets in different places there.

          test groupings

          Only big feedback I have, is there some way we could have a single parent test for each FS that runs all its contracts? All the concrete TestFooBarContract classes are basically copy paste, I'd like to get rid of them. It's also harder for poor me to run all the HDFS contract tests

          -1 to any unified supertest, as it doesn't isolate things the way having tests per operation does. You get to
          implement the features you want, and don't do a test for a RootContract if you don't want your root FS deleted,
          Append if you don't do append. etc. You also get to debug something TestHDFSRenameContract

          1. We can do well known names like TestHDFSContract, I can see that I've already done this for
            the TestNativeS3* tests.
          2. There's Junit Categories[ http://junit.org/javadoc/4.11/org/junit/experimental/categories/Categories.html].
            Maven does now support this
            FWIW, categorizing the Hadoop tests would be a good idea at some point in the future anyway "fast, slow, scale"
          3. There's JUnit suites -but use them and you will end up with your tests running if the suite test runs -and
            again if run individually.

          I'd go for the naming, if everyone is happy with that and come up with a good name for the HDFS tests that don't class with other
          things. How about TestHDFSContract*?

          FSExceptionMessages

          I picked them up from one file (HDFS?) and used there.

          Everything else

          I'll do those...

          How about "rejects-seek-past-eof"?

          Steve Loughran added a comment - Validating S3/Swift tests. It's still hard for me to run the S3 / Swift tests since I'd have to get credentials, These tests cost ~$0 to run as they don't persist data; you can use your own private logins. I'd recommend >1 swift provider (I use RAX US, RAX UK and HP Cloud for their different auth, consistency and throttling). S3 has different consistency models for US-east (worst) and everywhere else. You need to create buckets in different places there. test groupings Only big feedback I have, is there some way we could have a single parent test for each FS that runs all its contracts? All the concrete TestFooBarContract classes are basically copy paste, I'd like to get rid of them. It's also harder for poor me to run all the HDFS contract tests -1 to any unified supertest, as it doesn't isolate things the way having tests per operation does. You get to implement the features you want, and don't do a test for a RootContract if you don't want your root FS deleted, Append if you don't do append. etc. You also get to debug something TestHDFSRenameContract We can do well known names like TestHDFSContract , I can see that I've already done this for the TestNativeS3* tests. There's Junit Categories[ http://junit.org/javadoc/4.11/org/junit/experimental/categories/Categories.html ]. Maven does now support this FWIW, categorizing the Hadoop tests would be a good idea at some point in the future anyway "fast, slow, scale" There's JUnit suites -but use them and you will end up with your tests running if the suite test runs -and again if run individually. I'd go for the naming, if everyone is happy with that and come up with a good name for the HDFS tests that don't class with other things. How about TestHDFSContract* ? FSExceptionMessages I picked them up from one file (HDFS?) and used there. Everything else I'll do those... How about "rejects-seek-past-eof" ?

          Let's give Steve a little while to rework the patch first I'm not hung up on this point, but I'd like to see this attempted pre-commit because it might result in a lot of code churn. Let's also just say that follow-on JIRAs are not always finished

          Hey Jay, perhaps, but it looks like there'd still be the boilerplate for each inner class. Ideally, all we'd for each FS would be the xml file and a small parent test that provides the filesystem to be tested. Let's see how close we can get to that.

          Hi Steve,

          I'm going to take it on faith that you applied all the doc improvements, since honestly there's too much too look through Going to focus on code questions this time around. It's still hard for me to run the S3 / Swift tests since I'd have to get credentials, but I can do it if needed.

          • Only big feedback I have, is there some way we could have a single parent test for each FS that runs all its contracts? All the concrete TestFooBarContract classes are basically copy paste, I'd like to get rid of them. It's also harder for poor me to run all the HDFS contract tests.
          • site.xml, link is still not quite right, should be filesystem/index.html
          • FSExceptionMessages, should we re-use the Java messages for these exceptions? I think they're a bit different. There are also a bunch of places where these strings aren't used, but unifying it everywhere is a tall order. Maybe a follow-on JIRA. Another maybe nice follow-on would be having a factory method for things like FileAlreadyExistsException where we stitch something to a string.
          • I'd prefer to flip "fs.contract.supports-seek-past-eof" so we can have all trues for HDFS's contract. Strawman, "supports-exception-on-seek-past-eof"?
          • Jets3tnative: typo: maxListingLengthm
          • Jets3tnative: there are two handleBlahException methods that just delegate to handleException. Can we just get rid of them?
          • NativeS3, read's LOG.info has an extra "{}"
          • Some Contract class javadocs are inconsistent. HDFSContract's class javadoc says "Local filesystem". SwiftContract mentions S3N.

          I think we're pretty close, modulo the big one. Thanks again for the effort here.

          1. incorporates all of Andrew's modifications. Andrew - thanks for putting in the effort!
          2. added a section on object stores in the introduction, to clarify how they are different.

          Once we add a `Blobstore` marker to object stores, we can expand that a bit more.

          Cool, thanks Steve. Here's a patch with a bunch of docs changes. I applied your base patch to git hash b7da01dea546746e34195882df0dee789bc2e3c5 (the trunk HDFS-6268 commit), then made this one on top of that. There's a lot of content here, so I won't claim to have caught everything, but hopefully it'll help you refine the text.

          I also had some other higher level comments about the text (haven't looked at the code yet):

          High-level/misc:

          • [Wikipedia](https://en.wikipedia.org/wiki/Dash#En_dash_versus_em_dash) is enlightening on the subject of em and en dashes, it seems like an unspaced em-dash () may be slightly more canonical than a spaced en-dash (). I used the unspaced emdash.
          • I assume we wanted to say "FileSystem" with camel casing in a lot of places. Please check the rest.
          • Also tried to use the Oxford comma everywhere, it varied in your writing.
          • A table of contents would be useful for the bigger pages.

          Introduction

          • Maybe should define what a "blobstore" is? Opinions vary, I've heard people call HDFS a "blobstore" before because it's append-only and not POSIX.
          • What is "immediate consistency"?
          • In Atomicity, note that we don't actually implement mkdir in FileSystem, but mkdirs.
          • Link for "one-copy-update-semantics"? Also, while HDFS does support this, it requires some hoops with reopening the DFSInputStream to get the new file length of files being written. Bit of a caveat.
          • Concurrency and consistency are separate sections? I'm not sure what the difference is.
          • "HDFS: 8000", is this bytes or characters?
          • The "undefined limits" and "undefined timeouts" come off as commentary, should we be sprinkling SHOULD around, or giving more advice about "typical" expectations?

          Notation

          • In Exceptions, it says that you can provide a set of exceptions, but you used list syntax. Wasn't sure here, so I switched it to set syntax (curly braces).

          Model:

          • I think "path component" is a more standard term than "path element"?
          • Paths are URIs in Hadoop, is that worth mentioning here? Path URI normalization is also complicated, things like extra slashes and ".." are (I believe) sometimes normalized out.
          • Where is it specified how to turn a path into path components? There's also a need to strip out parts of the URI like the scheme and authority.
          • ancestors doesn't have preconditions
          • I'm not sure we'll ever get symlinks in FileSystem to be honest, I'd consider just removing these references.
          • isDescendant definition refers to itself, is this right?
          • Dunno how to parse the "File references statement" about data dictionary
          • dangling sentence in "User home"

          Filesystem:

          • Looking at the code, getBlockLocations takes a Path, and throws a FileNotFoundException if it doesn't exist.
          • The cluster topology stuff seems like a non-sequiter, maybe more explanation?
          • append Postconditions, just "FS"?
          • "the file and its data is still", dunno how to parse this
          • Worth mentioning permissions as related to recursive delete? I know permissions are assumed, but IIRC the atomicity still holds.
          • I'm wondering about the use of MUST with regard to atomicity of recursive delete. In other places, you mention that behavior is undefined or implementation-dependent, but here you say it's a MUST but these other FileSystems don't support it.

          FSDIS:

          • Close in a distributed filesystem is a thorny problem. Have you seen HDFS-4504? I've also heard of Flume and HBase errors related to close continually throwing IOException, not sure of the current status.
          • Mention and formatting of exceptions is not uniform. InputStream.read is one example, it doesn't use the list syntax, and NullPointerException is mentioned in the preconditions box but not the exceptions box.
          • Invariants are not uniformly formatted
          • Formatting of true and false is not uniform (e.g. True and true in text).
          • seekToNewSource, irregular use of terms "files" and "blocks", not sure if you wanted to avoid talking about blocks entirely, or instead wanted to define both terms
          • I think we could use some more rigor in the Consistency section, some of it seems underspecified

          Testing:

          • Note that "LocalFS" is a FileContext class, LocalFileSystem is probably what you want. Haven't looked at the code yet, but might need to rename some things.
          • Rather than saying "Windows and OS/X filesystem", can we go further and say, e.g. HPFS, NTFS, FAT, etc?
          • I can't parse the paragraph beginning with "A recommended strategy"
          • Definition of concurrency vs consistency again?

          Hey Steve, would it be appropriate if I attached an addendum patch with doc improvements? I think that'd be easier than posting a gigantic review of "capitalize this" or "reword that". You could then re-integrate them if you agree. I'll still post any code review comments here on JIRA.

          any meet up would come after.

          1. it's not a change, just a documentation of what HDFS does and tightening of the others -driven by tests on their behaviour
          2. Suresh has spent a few hours reviewing it, don't worry.
          3. we need the fixes to S3N in as soon as possible, as the jets3t migration triggers NPEs without tightened error handling. Everything else is really tests which don't break anything and tightened exceptions. Which, as they are made closer to HDFS, "shouldn't".

          Thanks Steve. I wasn't planning on attending Summit, but if there's a particularly good day (like say an HDFS meetup), I can try and come. I suspect that we'll be able to work most stuff out via JIRA and upstream lists though.

          It seems a little scary that essentially just the two of us could push through something as powerful as a FileSystem spec without sign-off from the rest of the community, but I guess at this point everyone's had ample time to comment if they care. We should probably re-ping the dev list before actual commit though just to be safe.

          This is also something we might consider baking in trunk before backporting to branch-2. There'll still be immediate value too, since it'll be running on precommit at that point.

          Jay -what I'm thinking of is that functional filesystem tests written in the bigtop project may want to make use of some of the information. What is there today is low-level, and covers details needed for the basic filesystem tests, but what would be interesting is information on the limits of the filesystem

          1. the maximum number of files in a directory
          2. the maximum path length in the filesystem
          3. the maximum length of a directory entry
          4. the maximum file size

          these can be used for stress tests -though of course they'd need to be overrideable by individuals/test runs.

          this is stuff that could/should be kept together with the other details. The hadoop build keeps XML and properties resources out of the test JARs, which is normally good: it stops log4j files sneaking it, or people's site.xml files with login details accidentally being published. its just we may want at some time in the future to publish this -for testers rather than apps in general

          Steve Loughran added a comment - Jay -what I'm thinking of is that functional filesystem tests written in the bigtop project may want to make use of some of the information. What is there today is low-level, and covers details needed for the basic filesystem tests, but what would be interesting is information on the limits of the filesystem the maximum number of files in a directory the maximum path length in the filesystem the maximum length of a directory entry the maximum file size these can be used for stress tests -though of course they'd need to be overrideable by individuals/test runs. this is stuff that could/should be kept together with the other details.

          "These are in the test JARs to stop them being used by code, though I'd like them (somehow) to get down to any functional tests in Bigtop."

          ^^ can you clarify what you meant by that? Certainly there is a overlap of stuff bigtop should be aware of here so it will be good to update or fs tests like TestCli jiras in context of this.

          Patch with changes

          1. fixed a findbug warning about unused private method
          2. fixed a deprecation warning about use of Path.makeQualified()
          3. reviewed the new S3N exception translation logic and enhanced it with a change in the recursion termination process and with no wrap of any final IOE at that end stage

          looking at the warnings. I think that test failure is a false alarm, but will resubmit to see; I've also tuned s3n's exception logic a bit -that's a bit of a troublespot.

          Andrew, most of this is documentation -what HDFS does and where other filesystems differ within their "correct" operation, fixes for the other filesystems to make them more consistent with HDFS and more robust -especially to seek() and close(). For HDFS, all that changes is that out of range seeks are raised as EOFException instead of simple IOException - with the text unchanged in case people were looking for that in their code.

          The thing I'd like input on is actually that specification. Does it make sense -and can you see obvious mistakes in it. Rename() is the troublespot, incidentally -in the spec, the implementation and the tests. As for the tests, they've got a more contract-driven architecture, with an XML file for each FS defining behaviour, e.g hdfs.xml. These are in the test JARs to stop them being used by code, though I'd like them (somehow) to get down to any functional tests in Bigtop.

          Have a look at that specification and call out troublespots.

          I'll be in the US after hadoop summit if you want to talk on it, though JIRA is where detailed feedback should go for the historical record.

          I wasn't planning on attending Summit, but my quick skim of the patch was that the bulk of it was testing and documentation, which I think I can get through without too much hand holding. I'd need to read through it anyway before we could talk about FS semantics, which is I think the real meat of this patch.

          Hey Steve, this is a big patch but I'd like to help review. Do you have any kind of feedback in particular you're looking for? I don't have exposure to the various FileSystems besides local and HDFS, but I can at least look for potential compat issues (I see return types and exception types being changed), and also proofread the documentation you added. Running the Swift and S3 tests might be a bit hard too, so I'll just trust you that they work

          If you want to attack this piece by piece, I'll also wait for the patch split.

          This iteration has the following main changes

          1. docs cover testing and extending the specification
          2. tests have options for specific behaviours of HDFS and local fs on rename corner cases (overwrite, destination is nonexistent directory)
          3. FTP mostly works, except for the detail that rename() fails consistently.
          4. Swift FS exceptions are in sync with what the contract tests expect, as well as the existing tests.
          5. S3N has all the fixes need for HADOOP-10589 -as well as the tests to show the issue.

          I think this is complete enough to go in -if jenkins is happy. We just need to split up the individual patches into manageable units : core+ local ,hdfs, s3, ftp, swift for actual application. Given the state of s3, I'd give that priority.

          If someone wants to run these tests, have a look at the testing.md file -it explains how to do it.

          Pending a decision on what to do with HDFS-6262 - i.e. fix it or not - this patch should be ready to go in. It's not complete coverage of the filesystem semantics, but it can be extended over time, with the new test framework.

          Updated patch

          1. explicit option for an FS to not fail on a seek() on a closed file, only on the read that follows.
          2. add raw local tests that bypass the ChecksumFilesystem -mostly to see where quirks lay -and a couple that go down to Java's File class just to make sure.
          3. more tests on rename behaviour

          Outstanding "ambiguities"

          Major: rename file onto file

          On OS/X, LocalFS (and RawLocal) let you rename a source file over a destination file; the source data becomes accessible at the source path. This is what mv does at the command line, so presumably it's legitimate, even if HDFS and the blobstore APIs all reject this.

          This is a major difference in semantics from HDFS and Posix filesystems -code I've written to assume that renaming a file fails if the destination exists works well to implement some implicit concurrency control on HDFS, but would not work on a Posix FS.

          We have the option of making the rename operation stricter by explicitly adding a check into rawlocal, but there's still a race condition between any check and the OS-level rename action.

          What does that leave? It leaves documenting this somewhere for end-users.

          Minor:

          RawLocal returns true if you attempt to delete a nonexistent path; everything else (including File.delete()) returns true. This behaviour comes from FileUtil.fullyDelete(f), which does not check for a file existence first, and when it gets false back from File.delete() generates the return code !File.exists(). That is, the semantics of fully delete are "return true if there is no directory at the end of the operation"

          More subtly, it there is a small a race condition where you could accidentally recursively delete a directory by attempting to delete a nonexistent file while another process is creating a directory of the same name

          This is because the check for !isFile() and !recursive are false when the file does not exist, but by the time the delete operation starts the rename has created a directory tree.

              File f = pathToFile(p);
              if (f.isFile()) {
                return f.delete();
              } else if (!recursive && f.isDirectory() && 
                  (FileUtil.listFiles(f).length != 0)) {
                throw new IOException("Directory " + f.toString() + " is not empty");
              }
              return FileUtil.fullyDelete(f);
            }
          

          Adding an existence check at the start of the sequence produces a consistent return code and eliminates this aspect of the race condition -this patch does exactly that.

          There is still a minor race: adding an entry to a directory after the empty check and before the fullyDelete call.

          the recursive flag logic should really be moved into a FileUtil method itself.

          Patch with spec consistent with almost all HDFS behaviour, s3 and localfs set up to throw tighter exceptions on some failures, and to throw EOFException on seek(-negative).

          LocalFS behaviours to resolve

          1. attempting to mkdir over an existing file returns false instead of raising an exception.

          propose: raise an exception. Nobody ever checks the return code from mkdirs after all -so we should uprate it to be on a par with HDFS.

          2. you can seek on an stream valid after a close()

          options:

          • fix
          • ignore on the basis reads or writes will fail when attempted

          3. if you rename a file over an existing file, the operation succeeds. This is what bash does.

          propose: document as the less preferred option; relax test to permit with a warn

          HDFS contract test behaviours

          1. if you open a stream for append, rename the file and then do the append, the old filename remains.

          Propose: specify the outcome as "undefined"

          2. if you attempt to rename a file that doesn't exist to a path in the same directory, it returns false, rather than raising a FileNotFoundException

          I'm assuming here that the dest path is being checked before the source. I'd consider this an error

          3. delete("/", true) returns false and doesn't delete anything

          I've documented this as valid behaviour, and noted it is what HDFS does.

          This updates the tests with

          1. SwiftFS contract (now that HADOOP-8545 is in)
          2. appends contract test, with HDFS the
            only tested implementation.

          There's an issue with append that this test shows up (it fails), which is: what happens if a file that is being appended to is renamed?

          In HDFS, the answer appears to be "it keeps the old name", though the test doesn't explore in detail what has happened.

          Steve Loughran added a comment -

          The latest patch now has tests for : create, open, delete, mkdir and seek. I'm ignoring the rename tests as I need to fully understand what HADOOP-6240 has defined first.

          seek

          1. I've been through the code and fixed wherever a -ve seek was either ignored or raised an IOException into an EOFException. This
            included changes to ChecksumFileSystem, RawLocalFileSystem, BufferedFSInputStream (which also handles a null inner stream without NPEing), FSInputChecker.java
          2. pulled in the test from HADOOP-9307 to do many random seeks and reads; the #of seeks is configurable, so that remote blobstore tests don't take forever unless you want it to (or are running them in-cluster)
          3. some filesystems let you seek over a closed stream. I've fixed the NPE in BufferedFSInputStream, not sure it is worth the
            effort of fixing this everywhere.

          NativeS3 issues/changes changes

          • Jets3tNativeFileSystemStore converts the relevant S3 error code "InvalidRange" into an EOFException
          • Amazon S3 rejects a seek(0) in a zero-byte file; not fixed yet as you need to know the file length to do it up front. Maybe an EOFException on a seek could be downgraded to a no-op if the seek offset is 0.
          • throws a FileAlreadyExistsException if trying to create a file over an existing one, and !overwrite
          • I'm deliberately skipping the test where we expect creating a file over a dir to fail even if overwrite is true, because blobstores use 0-byte files as a pretend directory.
          • It's failing a test which creates overwrites a directory which has children. This could be picked up (look for children if overwriting a 0-byte file)
          • It fails a test that a newly created file exists while the write is still in progress; as the blobstores only write at the end of the file, it doesn't. this is potentially a race condition -we could create a marker file here and overwrite it on the close.

          FTP

          I'll cover that in in HADOOP-9712 as its mostly bugs in a niche FS.

          LocalFS

          • throws FileNotFoundException when attempting to create a dir where the destination or a parent is a directory. This happens inside the JDK and has to be a WONTFIX, unless it is caught and wrapped.

          Steve Loughran added a comment - The latest patch now has tests for : create, open, delete, mkdir and seek. I'm ignoring the rename tests as I need to fully understand what HADOOP-6240 has defined first. seek I've been through the code and fixed wherever a -ve seek was either ignored or raised an IOException into an EOFException . This included changes to ChecksumFileSystem , RawLocalFileSystem , BufferedFSInputStream (which also handles a null inner stream without NPEing), FSInputChecker.java pulled in the test from HADOOP-9307 to do many random seeks and reads; the #of seeks is configurable, so that remote blobstore tests don't take forever unless you want it to (or are running them in-cluster) some filesystems let you seek over a closed stream. I've fixed the NPE in BufferedFSInputStream , not sure it is worth the effort of fixing this everywhere. NativeS3 issues/changes changes Jets3tNativeFileSystemStore converts the relevant S3 error code "InvalidRange" into an EOFException Amazon S3 rejects a seek(0) in a zero-byte file; not fixed yet as you need to know the file length to do it up front. Maybe an EOFException on a seek could be downgraded to a no-op if the seek offset is 0. throws a FileAlreadyExistsException if trying to create a file over an existing one, and !overwrite I'm deliberately skipping the test where we expect creating a file over a dir to fail even if overwrite is true, because blobstores use 0-byte files as a pretend directory. It's failing a test which creates overwrites a directory which has children. This could be picked up (look for children if overwriting a 0-byte file) It fails a test that a newly created file exists while the write is still in progress; as the blobstores only write at the end of the file, it doesn't. this is potentially a race condition -we could create a marker file here and overwrite it on the close. FTP I'll cover that in in HADOOP-9712 as its mostly bugs in a niche FS. LocalFS throws FileNotFoundException when attempting to create a dir where the destination or a parent is a directory.

          This is up as a work in progress; if you add the right details to the auth-keys.xml file in common/src/test/resources it will test S3n and ftp filesystems as well as local; HDFS adds its tests too.

          Some variances

          1. HDFS won't let you rm / even if empty, or rm -rf /.
          2. FTP throws FileNotFoundException if you try to delete a file that isn't there.
          3. FTP (the back end?) will overwrite a directory with a file creation.
          4. RawLocalFS.rename() will try to do a File.rename() operation and fall back to a copy, this is the outstanding issue from HDFS-303, "What should consistent rename actions be"
          5. S3n will not only let you overwrite a dir with a file (side effect of how blobstores use 0-byte files as dir markers), it will do this even if the destination has children. It could check for that

          Thanks Steve for starting this. Personally I'm really glad to see more abstract testing-against-the-contract efforts for the file systems in Hadoop so it's great to see this. My comments upon first reading of the code (I didn't read the specs yet so no comments on those):

          1. Personal aesthetic point: I'd have personally preferred if the contract was not in XML config, but just in code; and that isSupported() just took an enum that provided the feature. Code is much easier and simpler to read in this case, and there's no real need to "configure" a contract for a file system. And already you modify the configuration based on code in e.g. LocalFSContract, so it's just easier to read if it was all in code.
          2. Typo: SUPPORTS_CONTAT should be SUPPORTS_CONCAT
          3. In assertPathExists(), I think you meant to include the ls() content in the fail() message rather than just call it.
          4. In testConcatOnSel() - missed failing if an error isn't thrown.
          5. It would be great to catch() more specific exceptions in the Concat tests - i.e. have the contract specify what exception to expect as well as just an exception being thrown.

          This patch

          1. specifies the a hadoop filesystem
          2. begins the notion of FS contract tests, with a Hadoop-compatible filesystem modeled as a set of paths mapping to data and metadata.
          3. defines a few initial tests: directory operations, seek operations (lifted from the HADOOP-8545 tests), and a test suite for FileSystem.concat()

          Tries to define the behaviour of the FileSystem class rigorously

          1. It does this with a model of a filesystem as a set of paths mapping to metadata and data, which lets us use set-theory to select parts of the filesystem, and in describing how a modified filesystem is derived from is predecessor as a result of an operation.
          2. specifying the preconditions and postconditions of the main operations -based on the behaviour of HDFS.
          3. begins the notion of FS contract tests, with a Hadoop-compatible filesystem modeled as a set of paths mapping to data and metadata.
          4. defines a few initial tests: directory operations, seek operations (lifted from the HADOOP-8545 tests), and a test suite for FileSystem.concat()

          Every filesystem to be tested must implement a subclass of AbstractFileSystemContract which contains a factory for their FileSystem
          instances (and could easily do the same for FileContext, as well as a method boolean supports(feature:string) that returns true/false
          for features like "supports-append". For the local fs and HDFS, the definition of supported features is done from XML config files, using
          keys like fs.$filesystem.contract.supports-append. This allows the future option for these declarations to move into the core- XML files.
          The LocalFSContract class updates some of its supported features (is-case-sensitive, supports-unix-permissions) based on the
          features of underlying FS. Every contract also has a couple of test-only features: supports-root-tests (can you do things like rm / in
          a test run?) and a method to see if the tests are enabled (boolean enabled()). This lets contract test suites disable themselves if they can't run (i.e when the logon details for
          a blobstore aren't in the test configurations). The enabled() option is checked in the test setups; the other features can be tested in the
          specific tests -and all downgrade to a skipped test if not set. This makes it visible which tests have not actually run.

          Instantiates contract tests for the localFS and HDFS. Note that LocalFS fails the seek tests, as it downgrades negative seeks to a no-op.

          Having written these tests, I can see some limitations of the process.

          • the tests have to look for the loosest exception type coming back from a failure -e.g. IOException over EOFException.
          • needs a story for timeouts: we must have these to deal with blobstores &c, and either need a way to allow FS contracts to define these, let the FS specific tests define them, or just have some base timeouts large enough to deal with blobstores with operations like delete(dir) being O(children(dir))

          Specification Syntax

          I'm not convinced the syntax for specifications is great, nor am I sure I'm even using it consistently. I've just had
          to do something minimal that fits into unformatted text in a .apt file:

          FileSystem.listStatus(Path P, PathFilter Filter) 
          
          A PathFilter) is a predicate function that returns true iff the path P
          meets the filter's requirements.
          
            Preconditions
          
          -----------
          
            #path must exist
            exists(FS, P) || throw FileNotFoundException
            
          -----------
          
            Postconditions
            
          -----------
          
            isFile(FS, P) && Filter(P) => [FileStatus(FS, P)]
            
            isFile(FS, P) && !Filter(P) => []
            
            isDir(FS, P) => [all C in children(FS, P) where Filter(C) == true] 
            
          -----------
          

          This blurs C/Java symbols with bits of set theory, and trying to define what exceptions to throw
          on failed preconditions is something that really needs improving.

          If we could use LaTeX we could do proper set syntax, though we'd still need a consistent language
          for defining filesystem implementation behaviours.

           
          isFile(FS, P) \land \neg Filter(P) \Rightarrow \emptyset
          
          isDir(FS,P) \Rightarrow  \left\{ \forall C \in children(FS, P) : Filter(C) \right} 
          

          This is actually harder to read.

          One other tactic could be to move the specification entirely to javadocs, with something at the package level for
          the core model & notation, then add precond/postcond specifics as preformatted areas in the docs.

          This would keep the spec by the signature, increase likelihood of maintenance, and for those people who
          understood the syntax, be able to understand what the methods do.

          This is my first prototype of a contract-driven FS test suite. Every FS has to implement AbstractFSContract, which provides an FS factory, test working dir and report whether various options are supported (and eventually, limits). Options include things like supports-unix-permissions and is-case-sensitive, as well as test options like root-tests-enabled -that being a flag which, if set, enables tests to do things to a root dir like renaming and deleting it.

          There is a contract for Local FS, which fail because the seek operations of local don't quite follow the expectations of HADOOP-9495, which is something to consider. That FS contract dynamically chooses case sensitivity and unix-permissions features based on the OS it is running.

          These tests must all be enabled/disabled dynamically by the FS specific subclasses, so that tests that can run against a filesystem for any reason (e.g. no S3 credentials) can be downgraded to a skip -which then appears in the test reports. This will make clear that tests were not run, whereas today the JUnit3-derived tests are named to not match the *Test pattern, and must be explicitly run by hand.
