This adds an `-allowdeprecated` CLI parameter whose value is a flag
indicating a deprecated feature that should be explicitly enabled.
Multiple instances of this argument may be provided. In the case that
this parameter is not provided, all currently deprecated RPC methods
that are not slated for removal in the next release remain available.
A user may disable all deprecated features entirely by providing the
string "none" as the argument to this parameter, or enable all
deprecated features, including those slated for removal, by providing
the string "all" as the argument to this parameter. In the case that
"all" or "none" is specified, multiple invocations of `-allowdeprecated`
are not permitted.
To explicitly enable only a specific set of deprecated features, use
`-allowdeprecated=<flag1> -allowdeprecated=<flagN> ...` when starting
zcashd. The following flags are recognized:
- "all" - enables all deprecated features.
- "none" - disables all deprecated features.
- "legacy_privacy" - enables the use of the deprecated "legacy" privacy
policy for z_sendmany. This causes the default behavior to conform to
the `FullPrivacy` directive in all cases instead of just for
transactions involving unified addresses.
- "getnewaddress" - enables the `getnewaddress` RPC method.
- "z_getnewaddress" - enables the `z_getnewaddress` RPC method.
- "zcrawreceive" - enables the `zcrawreceive` RPC method.
- "zcrawjoinsplit" - enables the `zcrawjoinsplit` RPC method.
- "zcrawkeygen" - enables the `zcrawkeygen` RPC method.
- "addrtype" - when this option is set, the deprecated `type` attribute
is returned in addition to `pool` or `address_type` (which contain the
same information) in the results of RPC methods that return address metadata.
- `--help`, `--version` etc should exit with `0` i.e. no error ("not enough args" case should still trigger an error)
- error reading config file should exit with `1`
Slightly refactor AppInitRPC/AppInitRawTx to return standard exit codes (EXIT_FAILURE/EXIT_SUCCESS) or CONTINUE_EXECUTION (-1)
Add message directing users to security guide
Addresses #2142, which was blocking on updates to zcash/support/security.html. That page has now been added, so this message directing users to the site can be included.
It displays in the zcash-cli --help and --version message text, and on the zcashd metrics screen.
- *Replace usage of boost::asio with [libevent2](http://libevent.org/)*.
boost::asio is not part of C++11, so unlike other boost there is no
forwards-compatibility reason to stick with it. Together with #4738 (convert
json_spirit to UniValue), this rids Bitcoin Core of the worst offenders with
regard to compile-time slowness.
- *Replace spit-and-duct-tape http server with evhttp*. Front-end http handling
is handled by libevent, a work queue (with configurable depth and parallelism)
is used to handle application requests.
- *Wrap HTTP request in C++ class*; this makes the application code mostly
HTTP-server-neutral
- *Refactor RPC to move all http-specific code to a separate file*.
Theoreticaly this can allow building without HTTP server but with another RPC
backend, e.g. Qt's debug console (currently not implemented) or future RPC
mechanisms people may want to use.
- *HTTP dispatch mechanism*; services (e.g., RPC, REST) register which URL
paths they want to handle.
By using a proven, high-performance asynchronous networking library (also used
by Tor) and HTTP server, problems such as #5674, #5655, #344 should be avoided.
What works? bitcoind, bitcoin-cli, bitcoin-qt. Unit tests and RPC/REST tests
pass. The aim for now is everything but SSL support.
Configuration options:
- `-rpcthreads`: repurposed as "number of work handler threads". Still
defaults to 4.
- `-rpcworkqueue`: maximum depth of work queue. When this is reached, new
requests will return a 500 Internal Error.
- `-rpctimeout`: inactivity time, in seconds, after which to disconnect a
client.
- `-debug=http`: low-level http activity logging
The main thread spends time waiting for the DetectShutdownThread.
So why not just run this waiting loop function in the main thread?
One thread-stack less saves 4MB of virtual memory on 32-bit, and 8MB on
64-bit.
Always make a pid file, not only when `-daemon` specified.
This is useful for troubleshooting, for attaching debuggers and loggers
and such.
- Write the pid file only after the datadir lock was acquired
- Don't create or remove a pid file on WIN32, and also don't show the option
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.
As it says on the tin. It was deprecated in version 0.9, and
at some point it should be removed.
Removes the dependency of bitcoind on libbitcoin-cli.a. Move
some functions that used to be shared but are now only used in
bitcoin-cli.cpp to that file.
After this change, an error is printed (and exit code 1 is returned)
when the user tries to send RPC commands using bitcoind.
Adds a copyright and attribution message to the `-version` output
(the same as shown in the About dialog in the GUI).
Move the message to a function LicenseInfo in init.cpp.
Adds a `-version` or `--version` option to print just the version
of the program for bitcoind, bitcoin-cli and bitcoin-qt.
Also make it that `-help` can be used to display the help (as well as
existing `--help`). Up to now, `-help` was the only option that didn't
work with either one or two dashes.
