This commit improves a couple of issues surrounding the creation of the
btcd home directory.
First, the code was previously attempting to log any errors that occurred
while creating the directory using the logging system which is not
initialized at that point. Thus, nothing was displayed to the user.
Second, if any component of btcd home directory path already exists, but
is not a directory, such as in the case of symlinks, the error returned
from the os.MkDirAll call indicates the directory can't be created. While
this is true, it's not always the most helpful error to display to the
user. So, this commit adds logic to detect when the failure case is due
to an existing symlink and displays a nicer error message suggesting the
user check if the destination of the link is mounted.
Fixes#193.
This prevents a downgrade attack to the vulnerable SSLv3. While here,
go ahead and require at least TLS 1.2 since TLS 1.0 and 1.1 have their
own set of issues and it's only a matter of time before those would
need to be completely avoided as well.

Our policy is to only ensure the code compiles for the latest Go release
minus one version. Since Go 1.4 has now been released, this commit
updates TravisCI to remove Go 1.2 from the build matrix and add Go 1.3.
Also, go vet changed locations in between Go 1.3 and Go 1.4, so a check
has been added to download the appropriate version based on which version
of Go is running the integration tests.
Finally, the previous removed Go tip entry in the build matrix has been
reintroduced since it will now work again.
Now that Go 1.4 has been released, this commit reverts the recent changes
which dealt with allowing TravisCI to work with go tip in between the Go
1.3 and Go 1.4 release cycle and updates the .travis.yml to invoke test
coverage tool from the new path in Go 1.4.
As pointed out in #189, according to the Go documentation, a ticker must
be stopped to release associated resources. This commit adds a defer call
to stop two tickers there were previously not being stopped as well as
changes two others that were being stopped over to use defer so it's more
consistent.
The other ticker in ScheduleShutdown is replaced and already calls Stop
before replacing it, so it has not been modified.
Closes#189.

This commit addresses a few nitpicks in the recent getrawmppol update
which populates the starting and current priority fields.
In particular:
- Move the new calcInputValueAge function before the function which
invokes it so it is consistent with the rest of the mempool code
- Double space after periods for consistency
- Correct the comments for calcInputValueAge to indiciate that inputs
which are in the the memory pool count as zero toward the value age
rather than the incorrect claim that that the overal input value age is
zero when one of them does
- Rename endingPriority to currentPriority to match the RPC field and its
actual function
- Make the comment about using zero when input transactions can't be found
for some reason more accurate since there can be (and frequently is)
more than one input transaction
This commit modifies the .travis.yml to invoke a new script which has also
been added that gets the test coverage tool from the new path needed by go
tip.
This commit modifies the RandomUint64 function so that rather than
returning an io.ErrShortBuffer when the system does not have enough
entropy available, it now blocks until it does have enough. This means
that RandomUint64 will now always eventually succeed unless the entropy
source is closed (which only really ever happens when the operating system
is shutting down).
The tests have also been updated for the change in semantics to maintain
100% coverage.
Closes#23.
Since the result might not be set when the response does not contain one,
such as in the case when the command is not implemented by the server,
don't attempt to modify it until ensuring it exists.
This commit extends the same logic in the previous commit to the
comparison of offsets returned from the median time source in the tests.
In particular it modifies the tests to allow for the offsets to differ by
a second due to a boundary condition to prevent false positives.
The new median time tests perform a comparsion of the adjusted time
returned from the median time source to the expected value. However,
since time is always moving, it is possible the current time between the
call to the adjusted time function and the current time taken in the tests
for comparison just after the call differ by a second due to a boundary
condition. So, this commit modifies the tests to allow for this
condition.
This commit changes the internal testing mechanism from returning the
unexported timeSorter type directly to insted returning sort.Interface.
This has been done because the latest version of golint complains about
return unexported types.
This commit provides a new interface, MedianTimeSource, along with a
concrete implementation which allows improved accuracy of time by making
use of the median network time as calculated from multiple time samples.
The time samples are to be provided by callers and are intended to come
from remote clients.
The calculations performed in this implementation exactly mirror those in
Bitcoin Core because time calculations are part of the consensus rules and
hence need to match exactly.
This commit uses the new MedianTimeSource API in btcchain to create a
median time source which is stored in the server and is fed time samples
from all remote nodes that are connected. It also modifies all call sites
which now require the the time source to pass it in.
