lfs: enable workers by default

With the stall issue seemingly fixed, there's no reason not to use workers.  The
setting is left for now to keep the test output deterministic, and in case other
issues come up.  If none do, this can be converted to a developer setting for
usage with the tests.

 Prior to removing (EXPERIMENTAL)
 --------------------------------
 
 These things affect UI and/or behavior, and should probably be implemented (or
 ruled out) prior to taking off the experimental shrinkwrap.
 
 #. Finish the `hg convert` story
 
    * Add an argument to accept a rules file to apply during conversion?
      Currently `lfs.track` is the only way to affect the conversion.
    * drop `lfs.track` config settings
    * splice in `.hglfs` file for normal repo -> lfs conversions?
 
 #. Stop uploading blobs when pushing between local repos
 
    * Could probably hardlink directly to the other local repo's store
    * Support inferring `lfs.url` for local push/pull (currently only supports
      http)
 
 #. Stop uploading blobs on strip/amend/histedit/etc.
 
    * This seems to be a side effect of doing it for `hg bundle`, which probably
      makes sense.
 
 #. Handle a server with the extension loaded and a client without the extension
    more gracefully.
 
    * `changegroup3` is still experimental, and not enabled by default.
    * Figure out how to `introduce LFS to the server repo
      <https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-September/122281.html>`_.
      See the TODO in test-lfs-serve.t.
 
 #. Remove `lfs.retry` hack in client?  This came from FB, but it's not clear why
    it is/was needed.
 
 #. `hg export` currently writes out the LFS blob.  Should it write the pointer
    instead?
 
    * `hg diff` is similar, and probably shouldn't see the pointer file
 
-#. `Fix https multiplexing, and re-enable workers
-   <https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-January/109916.html>`_.
-
 #. Show to-be-applied rules with `hg files -r 'wdir()' 'set:lfs()'`
 
    * `debugignore` can show file + line number, so a dedicated command could be
      useful too.
 
 #. Filesets, revsets and templates
 
    * A dedicated revset should be faster than `'file(set:lfs())'`
    * Attach `{lfsoid}` and `{lfspointer}` to `general keywords
      <https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-January/110251.html>`_,
      IFF the file is a blob
    * Drop existing items that would be redundant with general support
 
 #. Can `grep` avoid downloading most things?
 
    * Add a command option to skip LFS blobs?
 
 #. Add a flag that's visible in `hg files -v` to indicate external storage?
 
 #. Server side issues
 
    * Check for local disk space before allowing upload.  (I've got a patch for
      this.)
    * Make sure the http codes used are appropriate.
    * `Why is copying the Authorization header into the JSON payload necessary
      <https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-April/116230.html>`_?
    * `LFS-Authenticate` header support in client and server(?)
 
 #. Add locks on cache and blob store
 
    * This is complicated with a global store, and multiple potentially unrelated
      local repositories that reference the same blob.
    * Alternately, maybe just handle collisions when trying to create the same
      blob in the store somehow.
 
 #. Are proper file sizes reported in `debugupgraderepo`?
 
 #. Finish prefetching files
 
    * `-T {data}`  (other than cat?)
    * `verify`
    * `grep`
 
 #. Output cleanup
 
    * Can we print the url when connecting to the blobstore?  (A sudden
      connection refused after pulling commits looks confusing.)  Problem is,
      'pushing to main url' is printed, and then lfs wants to upload before going
      back to the main repo transfer, so then *that* could be confusing with
      extra output. (This is kinda improved with 380f5131ee7b and 9f78d10742af.)
 
    * Add more progress indicators?  Uploading a large repo looks idle for a long
      time while it scans for blobs in each outgoing revision.
 
    * Print filenames instead of hashes in error messages
 
      * subrepo aware paths, where necessary
 
    * Is existing output at the right status/note/debug level?
 
 #. Can `verify` be done without downloading everything?
 
    * If we know that we are talking to an hg server, we can leverage the fact
      that it validates in the Batch API portion, and skip d/l altogether.  OTOH,
      maybe we should download the files unconditionally for forensics.  The
      alternative is to define a custom transfer handler that definitively
      verifies without transferring, and then cache those results.  When verify
      comes looking, look in the cache instead of actually opening the file and
      processing it.
 
    * Yuya has concerns about when blob fetch takes place vs when revlog is
      verified.  Since the visible hash matches the blob content, I don't think
      there's a way to verify the pointer file that's actually stored in the
      filelog (other than basic JSON checks).  Full verification requires the
      blob.  See
      https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-April/116133.html
 
    * Opening a corrupt pointer file aborts.  It probably shouldn't for verify.
 
 
 Future ideas/features/polishing
 -------------------------------
 
 These aren't in any particular order, and are things that don't have obvious BC
 concerns.
 
 #. Garbage collection `(issue5790) <https://bz.mercurial-scm.org/show_bug.cgi?id=5790>`_
 
    * This gets complicated because of the global cache, which may or may not
      consist of hardlinks to the repo, and may be in use by other repos.  (So
      the gc may be pointless.)
 
 #. `Compress blobs <https://github.com/git-lfs/git-lfs/issues/260>`_
 
    * 700MB repo becomes 2.5GB with all lfs blobs
    * What implications are there for filesystem paths that don't indicate
      compression?  (i.e. how to share with global cache and other local repos?)
    * Probably needs to be stored under `.hg/store/lfs/zstd`, with a repo
      requirement.
    * Allow tuneable compression type and settings?
    * Support compression over the wire if both sides understand the compression?
    * `debugupgraderepo` to convert?
    * Probably not worth supporting compressed and uncompressed concurrently
 
 #. Determine things to upload with `readfast()
    <https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-August/121315.html>`_
 
    * Significantly faster when pushing an entire large repo to http.
    * Causes test changes to fileset and templates; may need both this and
      current methods of lookup.
 
 #. Is a command to download everything needed?  This would allow copying the
    whole to a portable drive.  Currently this can be effected by running
    `hg verify`.
 
 #. Stop reading in entire file into one buffer when passing through filelog
    interface
 
    * `Requires major replumbing to core
      <https://www.mercurial-scm.org/wiki/HandlingLargeFiles>`_
 
 #. Keep corrupt files around in 'store/lfs/incoming' for forensics?
 
    * Files should be downloaded to 'incoming', and moved to normal location when
      done.
 
 #. Client side path enhancements
 
    * Support paths.default:lfs = ... style paths
    * SSH -> https server inference
 
      * https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-April/115416.html
      * https://github.com/git-lfs/git-lfs/blob/master/docs/api/server-discovery.md#guessing-the-server
 
 #. Server enhancements
 
    * Add support for transfer quotas?
    * Download should be able to send the file in chunks, without reading the
      whole thing into memory
      (https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-March/114584.html)
    * Support for resuming transfers
 
 #. Handle 3rd party server storage.
 
    * Teach client to handle lfs `verify` action.  This is needed after the
      server instructs the client to upload the file to another server, in order
      to tell the server that the upload completed.
    * Teach the server to send redirects if configured, and process `verify`
      requests.

 """lfs - large file support (EXPERIMENTAL)
 
 This extension allows large files to be tracked outside of the normal
 repository storage and stored on a centralized server, similar to the
 ``largefiles`` extension.  The ``git-lfs`` protocol is used when
 communicating with the server, so existing git infrastructure can be
 harnessed.  Even though the files are stored outside of the repository,
 they are still integrity checked in the same manner as normal files.
 
 The files stored outside of the repository are downloaded on demand,
 which reduces the time to clone, and possibly the local disk usage.
 This changes fundamental workflows in a DVCS, so careful thought
 should be given before deploying it.  :hg:`convert` can be used to
 convert LFS repositories to normal repositories that no longer
 require this extension, and do so without changing the commit hashes.
 This allows the extension to be disabled if the centralized workflow
 becomes burdensome.  However, the pre and post convert clones will
 not be able to communicate with each other unless the extension is
 enabled on both.
 
 To start a new repository, or to add LFS files to an existing one, just
 create an ``.hglfs`` file as described below in the root directory of
 the repository.  Typically, this file should be put under version
 control, so that the settings will propagate to other repositories with
 push and pull.  During any commit, Mercurial will consult this file to
 determine if an added or modified file should be stored externally.  The
 type of storage depends on the characteristics of the file at each
 commit.  A file that is near a size threshold may switch back and forth
 between LFS and normal storage, as needed.
 
 Alternately, both normal repositories and largefile controlled
 repositories can be converted to LFS by using :hg:`convert` and the
 ``lfs.track`` config option described below.  The ``.hglfs`` file
 should then be created and added, to control subsequent LFS selection.
 The hashes are also unchanged in this case.  The LFS and non-LFS
 repositories can be distinguished because the LFS repository will
 abort any command if this extension is disabled.
 
 Committed LFS files are held locally, until the repository is pushed.
 Prior to pushing the normal repository data, the LFS files that are
 tracked by the outgoing commits are automatically uploaded to the
 configured central server.  No LFS files are transferred on
 :hg:`pull` or :hg:`clone`.  Instead, the files are downloaded on
 demand as they need to be read, if a cached copy cannot be found
 locally.  Both committing and downloading an LFS file will link the
 file to a usercache, to speed up future access.  See the `usercache`
 config setting described below.
 
 The extension reads its configuration from a versioned ``.hglfs``
 configuration file found in the root of the working directory. The
 ``.hglfs`` file uses the same syntax as all other Mercurial
 configuration files. It uses a single section, ``[track]``.
 
 The ``[track]`` section specifies which files are stored as LFS (or
 not). Each line is keyed by a file pattern, with a predicate value.
 The first file pattern match is used, so put more specific patterns
 first.  The available predicates are ``all()``, ``none()``, and
 ``size()``. See "hg help filesets.size" for the latter.
 
 Example versioned ``.hglfs`` file::
 
   [track]
   # No Makefile or python file, anywhere, will be LFS
   **Makefile = none()
   **.py = none()
 
   **.zip = all()
   **.exe = size(">1MB")
 
   # Catchall for everything not matched above
   ** = size(">10MB")
 
 Configs::
 
     [lfs]
     # Remote endpoint. Multiple protocols are supported:
     # - http(s)://user:[e-mail]/path
     #   git-lfs endpoint
     # - file:///tmp/path
     #   local filesystem, usually for testing
     # if unset, lfs will assume the remote repository also handles blob storage
     # for http(s) URLs.  Otherwise, lfs will prompt to set this when it must
     # use this value.
     # (default: unset)
     url = https://example.com/repo.git/info/lfs
 
     # Which files to track in LFS.  Path tests are "**.extname" for file
     # extensions, and "path:under/some/directory" for path prefix.  Both
     # are relative to the repository root.
     # File size can be tested with the "size()" fileset, and tests can be
     # joined with fileset operators.  (See "hg help filesets.operators".)
     #
     # Some examples:
     # - all()                       # everything
     # - none()                      # nothing
     # - size(">20MB")               # larger than 20MB
     # - !**.txt                     # anything not a *.txt file
     # - **.zip | **.tar.gz | **.7z  # some types of compressed files
     # - path:bin                    # files under "bin" in the project root
     # - (**.php & size(">2MB")) | (**.js & size(">5MB")) | **.tar.gz
     #     | (path:bin & !path:/bin/README) | size(">1GB")
     # (default: none())
     #
     # This is ignored if there is a tracked '.hglfs' file, and this setting
     # will eventually be deprecated and removed.
     track = size(">10M")
 
     # how many times to retry before giving up on transferring an object

 This test splits `hg serve` with and without using the extension into separate
 tests cases.  The tests are broken down as follows, where "LFS"/"No-LFS"
 indicates whether or not there are commits that use an LFS file, and "D"/"E"
 indicates whether or not the extension is loaded.  The "X" cases are not tested
 individually, because the lfs requirement causes the process to bail early if
 the extension is disabled.

 Skip the experimental.changegroup3=True config.  Failure to agree on this comes
 first, and causes an "abort: no common changegroup version" if the extension is
 only loaded on one side. If that *is* enabled, the subsequent failure is "abort:
 missing processor for flag '0x2000'!" if the extension is only loaded on one side
 (possibly also masked by the Internal Server Error message).

 reposetup() on another repo actually being operated on.  This gives coverage
 that wrapper functions are not assuming reposetup() was called.

      preserved: dotencode, fncache, generaldelta, revlogv1, sparserevlog, store
   
   sidedata
      Allows storage of extra data alongside a revision.
   
   copies-sdc
      Allows to use more efficient algorithm to deal with copy tracing.
   
   beginning upgrade...
   repository locked and read-only
   creating temporary repository to stage migrated data: * (glob)
   (it is safe to interrupt this process any time before data migration completes)
   migrating 3 total revisions (1 in filelogs, 1 in manifests, 1 in changelog)
   migrating 324 bytes in store; 129 bytes tracked data

 When the server has some blobs already.  `hg serve` doesn't offer to upload

 actions property completely.
