the UTXO set"
This reverts commit da2ec100f3681176f60dec6dc675fc64147ade3a.
|
|
Split up util.cpp/h into:
- string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach)
- money utilities (parsesmoney, formatmoney)
- time utilities (gettime*, sleep, format date):
- and the rest (logging, argument parsing, config file parsing)
The latter is basically the environment and OS handling,
and is stripped of all utility functions, so we may want to
rename it to something else than util.cpp/h for clarity (Matt suggested
osinterface).
Breaks dependency of sha256.cpp on all the things pulled in by util.

da2ec10 Add a getutxos command to the p2p protocol. It allows querying of the UTXO set given a set of outpoints. (Mike Hearn)

aa82795 Add detailed network info to getnetworkinfo RPC (Wladimir J. van der Laan)
075cf49 Add GetNetworkName function (Wladimir J. van der Laan)
c91a947 Add IsReachable(net) function (Wladimir J. van der Laan)
60dc8e4 Allow -onlynet=onion to be used (Wladimir J. van der Laan)
|
|
Fixes #4679.
This leaves us with only one candidate, checkip.dyndns.org.
GetMyExternalIP should be phased out as soon as possible.

given a set of outpoints.
|
|
Allows other parts of the program to query for reachable
status of a network. Similar to IsLimited(net).
|
|
The goal is to increase independence and privacy.

eaedb59 net: add SetSocketNonBlocking() as OS independent wrapper (Philip Kaufmann)
|
|
0430c30 Add missing FindNode prototype to net.h (Wladimir J. van der Laan)
|
|
Also make the argument a const std::string & instead of pass-by-value.

- the call to CloseSocket() is placed after the WSAGetLastError(), because
a CloseSocket() can trigger an error also, which we don't want for the
logging in this two cases
|
|
|
|
Simpler alternative to #4348.
The current setup with closesocket() is strange. It poses
as a compatibility wrapper but adds functionality.
Rename it and make it a documented utility function in netbase.
Code movement only, zero effect on the functionality.

4eedf4f make RandAddSeed() use OPENSSL_cleanse() (Philip Kaufmann)
6354935 move rand functions from util to new random.h/.cpp (Philip Kaufmann)
001a53d add GetRandBytes() as wrapper for RAND_bytes() (Philip Kaufmann)

This adds a -whitelist option to specify subnet ranges from which peers
that connect are whitelisted. In addition, there is a -whitebind option
which works like -bind, except peers connecting to it are also
whitelisted (allowing a separate listen port for trusted connections).
Being whitelisted has two effects (for now):
* They are immune to DoS disconnection/banning.
* Transactions they broadcast (which are valid) are always relayed,
even if they were already in the mempool. This means that a node
can function as a gateway for a local network, and that rebroadcasts
from the local network will work as expected.
Whitelisting replaces the magic exemption localhost had for DoS
disconnection (local addresses are still never banned, though), which
implied hidden service connects (from a localhost Tor node) were
incorrectly immune to DoS disconnection as well. This old
behaviour is removed for that reason, but can be restored using
-whitelist=127.0.0.1 or -whitelist=::1 can be specified. -whitebind
is safer to use in case non-trusted localhost connections are expected
(like hidden services).

- add a small wrapper in util around RAND_bytes() and replace with
GetRandBytes() in the code to log errors from calling RAND_bytes()
- remove OpenSSL header rand.h where no longer needed

9f4da19 Use pong receive time rather than processing time (Pieter Wuille)

- SO_NOSIGPIPE isn't available on WIN32 so merge the 2 non-WIN32 blocks
- use predefined names from header for IPV6_PROTECTION_LEVEL and
PROTECTION_LEVEL_UNRESTRICTED

bitcoin-config.h moved, but the old file is likely to still exist when
reconfiguring or switching branches. This would've caused files to not rebuild
correctly, and other strange problems.
Make the path explicit so that the old one cannot be found.
Core libs use config/bitcoin-config.h.
Libs (like crypto) which don't want access to bitcoin's headers continue
to use -Iconfig and #include bitcoin-config.h.

f1920e8 Ping automatically every 2 minutes (unconditionally) (Pieter Wuille)

- remove an unneded else in ConnectNode()
- make 0 a double and change to 0.0 in ConnectNode()
- rename strDest to pszDest in OpenNetworkConnection()
- remove an unneded call to our REF() macro in BindListenPort()
- small style cleanups and removal of unneeded new-lines

... instead of after 30 minutes of no sending, for latency measurement
and keep-alive. Also, disconnect if no reply arrives within 20 minutes,
instead of 90 of inactivity (for peers supporting the 'pong' message).
|
|
rename fNoListen to fListen and move to net
|
|
NodeSyncScore() should find the node which we recv data most recently, so put a negative sign to pnode->nLastRecv is indeed wrong.
Also change the return value type to int64_t.

- better code readability and it belongs to net
- this is a prerequisite for a pull to add -listen to the GUI

d4e1c61 add DEFAULT_UPNP constant in net (Philip Kaufmann)

3e8ac6a Replace non-threadsafe gmtime and setlocale (Wladimir J. van der Laan)
a60838d Replace non-threadsafe strerror (Wladimir J. van der Laan)
|
|
Log the name of the error as well as the error code if a network problem
happens. This makes network troubleshooting more convenient.
Use thread-safe strerror_r and the WIN32 equivalent FormatMessage.

- as this is a shared Core/GUI setting, this makes it easier to keep them
in sync (also no new includes are needed)
|

Adds two new info query commands that take over information from
hodge-podge `getinfo`.
Also some new information is added:
- `getblockchaininfo`
- `chain`: (string) current chain (main, testnet3, regtest)
- `verificationprogress: (numeric) estimated verification progress
- `chainwork`
- `getnetworkinfo`
- `localaddresses`: (array) local addresses, from mapLocalHost (fixes #1734)
|
|
- also small logging text changes

The year is 2014. All supported operating systems have IPv6 support,
most certainly at build time (this doesn't mean that IPv6 is configured,
of course).
If noone is exercising the functionality to disable it, that means it
doesn't get tested, and IMO it's better to get rid of it.
(it's also not used consistently in RPC/boost and Net code...)

When we are over our outbound limit ThreadSocketHandler would try to
keep the connection if the peer was addnoded.
This didn't actually work for two reasons: It didn't actually run
the accept code due to mistaken code flow, and because we have a
limited number of outbound semaphores it couldn't actually use the
connection.
Instead it leaked the socket, which might have caused issue #4034.
This patch just takes out the non-functioning white-listing for now.

a486abd replace custom GetFilesize() with boost::filesystem::file_size() (Philip Kaufmann)
|
|
A slight improvement over 2d2d8fae3d8bc4e82dc631d93c6e19f954bbee04 -- we don't know that it's the daemon, it could be the GUI.
