Nagle appears to be a significant contributor to latency now that the static
sleeps are gone. Most of our messages are relatively large compared to
IP + TCP so I do not expect this to create enormous overhead.
This may also reduce traffic burstyness somewhat.

Fix two CSubNet constructor problems:
- The use of `/x` where 8 does not divide x was broken, due to a
bit-order issue
- The use of e.g. `1.2.3.4/24` where the netmasked bits in the network
are not 0 was broken. Fix this by explicitly normalizing the netwok
according to the bitmask.
Also add tests for these cases.
Fixes #6179. Thanks to @jonasschnelli for reporting and initial fix.

Simplify the code by using CAddress.ip directly, instead of the reversed
GetByte() semantics.

This avoids connecting to them again too soon in ThreadOpenConnections.
Make an exception for connection failures to the proxy as these
shouldn't affect the status of specific nodes.

- update help message text
- simplify code in init to check for -timeout
|
|
Avoids that SOCKS5 negotiation will hold up the shutdown process.
- Sockets can stay in non-blocking mode, no need to switch it on/off
anymore
- Adds a timeout (20 seconds) on SOCK5 negotiation. This should be
enough for even Tor to get a connection to a hidden service, and
avoids blocking the opencon thread indefinitely on a hanging proxy.
Fixes #2954.

`.c_str()` is only guaranteed to return the data up to the first NUL
character.

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.

All unused.

aa82795 Add detailed network info to getnetworkinfo RPC (Wladimir J. van der Laan)

|

- add comment for disabling sigpipe
- add closing comment in compat.h
- remove redundant check in net.h
|
|
Returns the network name for an Network enum.
|
|
Just an alias for onlynet=tor, but matches the new name
of the proxy option -onion= better.
|

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.

109849e Bugfix: strerror_r can return an error, and if it does, POSIX does not specify the content of the buffer (Luke Dashjr)
|
|
specify the content of the buffer
|
|
Problem introduced in caf6150. Thanks to @drak for noticing. Fixes #4473.
|
|
- now we support SOCKS5 only
|

In the LookupIntern(), things changed are:
1. Call getaddrinfo_a() instead of getaddrinfo() if available, the former is a sync version of the latter;
2. Try using inet_pton()/inet_addr() to convert the input text to a network addr structure at first, if success the extra name resolving thread inside getaddrinfo_a() could be avoided;
3. An interruption point added in the waiting loop for return from getaddrinfo_a(), which completes the improve for thread responsiveness.
A easy way to see the effect is to kick off a 'bitcoind stop' immediately after 'bitcoind -daemon', before the change it would take several, or even tens of, minutes on a bad network situation to wait for the running bitcoind to exit, now it costs only seconds.

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.
|
|
|
|
|
|
Use the new function parseint32 in SplitHostPort instead of calling
strtol directly.

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...)

in 2014.
contrib/devtools/fix-copyright-headers.py script to be able to perform this maintenance task with ease during the rest of the year, every year. Modifications to contrib/devtools/README.md to document what fix-copyright-headers.py does.

After the tinyformat switch sprintf() family functions support passing
actual std::string objects.
Remove unnecessary c_str calls (236 of them) in logging and formatting.
|
|
- example: if util.h includes stdint.h, remove it from util.cpp, as
util.h is the first header included in util.cpp
|
|
|
|
Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.

Using ! on a non-zero value will always return 0.
Also remove some duplicate and superfluous code in other places.

As memset() can be optimized out by a compiler it should not be used in
privacy/security relevant code parts. OpenSSL provides the safe
OPENSSL_cleanse() function in crypto.h, which perfectly does the job of
clean and overwrite data.
For details see: http://www.viva64.com/en/b/0178/
- change memset() to OPENSSL_cleanse() where appropriate
- change a hard-coded number from netbase.cpp into a sizeof()

Remove I2P support from netbase
|
|
get rid of strlcpy.h
|
|
I2P apparently needs 256 bits to store a fully routable address. Garlicat
requires a centralized lookup service to map the 80-bit addresses to fully
routable ones (as far as I understood), so that's not really usable in our
situation.
To support I2P routing and peer exchange for it, another solution is needed.
This will most likely imply a network protocol change, and extension of the
'addr' message.

Don't use hand-rolled string manipulation routine with a fixed
buffer in the bitcoin core, instead make use of c++ strings and boost.
