69e477f2d5 Use done channel to avoid goroutine leak
This deals with a memory leak, caused by goroutines, experienced when using the
s3 driver. Unfortunately, this section of the code leaks goroutines like a
sieve. There is probably some refactoring that could be done to avoid this but
instead, we have a done channel that will cause waiting goroutines to exit.

628c7fa77b Updated urlbuilder X-Forwarded-Host logic
According to the Apache mod_proxy docs, X-Forwarded-Host can be a
comma-separated list of hosts, to which each proxy appends the requested
host. We want to grab only the first from this comma-separated list
to get the original requested Host when building URLs.

f6d75a6139 Return after error in handler
This adds a missing return statement. It is not strictly needed since if the
io.Copy fails, the Finish operation will fail. Currently, the client reports
both errors where this new code will correctly only report the io.Copy error.

72a702d0d9 Allow configuration of chunksize parameter
The code using values from the yaml package wasn't careful enought with the
possible incoming types. Turns out, it is just an int but we've made this
section somewhat bulletproof in case that package changes the behavior.

This code likely never worked. The configuration system should be decoupled
from the object instantiation.

c8345090d9 Attempt to deal with eventual consistency by retrying
Rather than accept the resulting of a layer validation, we retry up to three
times, backing off 100ms after each try. The thought is that we allow s3 files
to make their way into the correct location increasing the liklihood the
verification can proceed, if possible.

registry/storage: automatically purge old upload files

e4f07c368b Automatically purge old upload files.
When the registry starts a background timer will periodically
scan the upload directories on the file system every 24 hours
and delete any files older than 1 week. An initial jitter
intends to avoid contention on the filesystem where multiple
registries with the same storage driver are started
simultaneously.

7420a3de10 Instantiate http context before dispatch
Ensure that the status is logged in the context by instantiating before the
request is routed to handlers. While this requires some level of hacking to
acheive, the result is that the context value of "http.request.status" is as
accurate as possible for each request.

142d62798e Rename top level registry interface to namespace
Registry is intended to be used as a repository service than an abstract collection of repositories. Namespace better describes a collection of repositories retrievable by name.
The registry service serves any repository in the global scope.

4d91e791c0 Disassociate instance id from application
This moves the instance id out of the app so that it is associated with an
instantiation of the runtime. The instance id is stored on the background
context. This allows allow contexts using the main background context to
include an instance id for log messages. It also simplifies the application
slightly.

84046e03e0 Prevent false sharing in signature fetch
The original implementation wrote to different locations in a shared slice.
While this is theoretically okay, we end up thrashing the cpu cache since
multiple slice members may be on the same cache line. So, even though each
thread has its own memory location, there may be contention over the cache
line. This changes the code to aggregate to a slice in a single goroutine.

In reality, this change likely won't have any performance impact. The theory
proposed above hasn't really even been tested. Either way, we can consider it
and possibly go forward.

registry/storage/driver: defer case-sensitive support to storage backend
2015-04-07 16:24:38 -07:00
Stephen J Day
e23ca5ac5f Defer case-sensitive support to storage backend
Rather than enforce lowercase paths for all drivers, support for
case-sensitivity has been deferred to the driver. There are a few caveats to
this approach:

1. There are possible security implications for tags that only differ in their
case. For instance, a tag "A" may be equivalent to tag "a" on certain file
system backends.
2. All system paths should not use case-sensitive identifiers where possible.
This might be problematic in a blob store that uses case-sensitive ids. For
now, since digest hex ids are all case-insensitive, this will not be an issue.

The recommend workaround is to not run the registry on a case-insensitive
filesystem driver in security sensitive applications.

1eab4b79bc Parallelize signature fetch in signature store
To avoid compounded round trips leading to slow retrieval of manifests with a
large number of signatures, the fetch of signatures has been parallelized. This
simply spawns a goroutine for each path, coordinated with a sync.WaitGroup.
