This commit corrects the error check from the createTxRawResult call in
handleGetRawTransaction. It was previously given a different name which
resulted in the wrong error being checked.
Fixes#196.
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.

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 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.
This change removes transactions from a newly connected block
from the orphan pool if they exist. Additionally, any orphan
transactions that are no longer orphan transactions are moved
to the mempool and inv'd to the currently connected peers.
This commit adds a couple of options which were not details in the sample
config file. It also fixes a couple of typos and makes the example default
maxpeers setting in the config file match the actual default used in btcd.
This commit explicitly ignores errors that were already intentionally
ignored in btcctl by using an _ to make the errcheck utility happy. It is
also nice to make it explicit that the error is being ignored
intentionally rather than leave questions of whether it was accidentally
forgotten.
This commit resolves a minor issue where an error in the config file would
prevent the help from being shown until the config file error was
resolved.
This results in the following behavior:
- With a malformed header:
$ ./btcd
Error parsing config file: ~/btcd/btcd.conf:14: malformed section header
Use btcd -h to show usage
- With an invalid option:
$ ./btcd
Error parsing config file: unknown option: bogus
Use btcd -h to show usage
- Invoking help with an error in the config file:
$ ./btcd -h
Usage:
...
- Invoking with an invalid command line option:
$ ./btcd --bogus=bogus
unknown flag `bogus'
Use btcd -h to show usage

This commit builds on the recent limiter updates. The recent changes
introduced a new function named calcTxFee which could easily be confused
with calculating the fees of the transaction rather than its intended
purpose of calculating the minimum transaciton relay fee.
Rather than taking that approach, this commit instead renames the existing
function to calcMinRequiredTxRelayFee and uses a consistent variable name
for the serialized size of a transaction. It then moves the check for
whether or not the check should be applied based on the serialized size of
the transcation and block priority to the call site.
This approach also has the benefit of avoiding two calls to the
calculation function since it's a local at the call site.
ok @jrick, @dajohi
Before, btcd was rate limiting all transactions that had a minimum
fee of zero. Now, btcd only rate limits transactions that contain
a fee less than the calculated fee based on size.
Closes#163
This ensures we backoff when reconnecting to peers for which we don't
understand the replies, just like we do for peers we fail to connect to.
Closes#103
The notification queue used for websocket client notifications had a
bug which caused the next queued item in some situations to not be
sent, but instead send a previously sent item. This change fixes this
by setting the 'next' variable to the next item which must be
dequeued, if the queue length is non-zero.
This bug did not always manifest itself as if the receiving goroutine
was ready, a queued item could be sent directly to it rather than
waiting in the queue to be sent at a later time.
This change modifies the behavior of the gettxout RPC to match the
behavior of the reference client. If a transaction output is spent by
a mined transaction, the handler will now return nil (JSON null).
While here, avoid indexing some slices multiple times, by creating a
local variable instead.
The sync.atomic requires alignment of variables used atomically on ARM.
This commit moves the connected and disconnect variables in the peer
struct up so they are aligned.
Fixes#157.
This commit prevents a race that could happen on shutdown if a sigint was
received between adding the first the interrupt handler and and future
handlers. This code is loosely based on initial pull request #154 which
was not accepted due to introducing a race of its own.
Thanks to @tuxcanfly for the intial pull request and finding the issue.
