Asking for a full histogram from a remote node (since it's
untrusted) is pretty slow, and spams the remote node, so
we replace it by only adding a second input if we have rct
ones, which are for all intents and purposes always mixable.
Minimum mixin 4 and enforced ringct is moved from v5 to v6.
v5 is now used for an increased minimum block size (from 60000
to 300000) to cater for larger typical/minimum transaction size.
The fee algorithm is also changed to decrease the base per kB
fee, and add a cheap tier for those transactions which we do
not care if they get delayed (or even included in a block).
This reverts commit d47dac9a88.
Callers actually expect the key to be payment id, so this
needs a lot more changes (like storing payment ids in the
structure, and possibly also to other existing structures
which do the same thing).
A relatedness check was meant to be done in the case of adding
an extra output if just one was enough. This was mistakenly
added to the "preferred output" case.
c02e1cb9 Updates to epee HTTP client code - http_simple_client now uses std::chrono for timeouts - http_simple_client accepts timeouts per connect / invoke call - shortened names of epee http invoke functions - invoke command functions only take relative path, connection is not automatically performed (Lee Clagett)
If a rct transaction can be made with just one input, a second
output will be added. This output will be the smallest amount
output available. However, if this output is a non rct output
with less available fake outs than requested, the transaction
will be rejected. We now check the histogram to only consider
outputs with enough available fake outs in the first place.
These warnings were emitted by clang++, and they are real bugs.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~
The obvious intent is achieved by using std::to_string().
- http_simple_client now uses std::chrono for timeouts
- http_simple_client accepts timeouts per connect / invoke call
- shortened names of epee http invoke functions
- invoke command functions only take relative path, connection
is not automatically performed
This would have tried to send a second output to make the tx
look like the 2/2 ideal, but it would not fail to find one
because picking an output from preferred_inputs priority list
did not remove it from the unused tranfer/dust outputs, so
it would try to send the same output twice.
While there, I also added a check to avoid sending a second
input if it's related to the first. Better 1/2 than linking
inputs, I think.
This avoids indirectly leaking the real output to the daemon,
and is faster.
This will still happen for more complex cases, especially
when cancelling a tx and "re-rolling" it.
This replaces the epee and data_loggers logging systems with
a single one, and also adds filename:line and explicit severity
levels. Categories may be defined, and logging severity set
by category (or set of categories). epee style 0-4 log level
maps to a sensible severity configuration. Log files now also
rotate when reaching 100 MB.
To select which logs to output, use the MONERO_LOGS environment
variable, with a comma separated list of categories (globs are
supported), with their requested severity level after a colon.
If a log matches more than one such setting, the last one in
the configuration string applies. A few examples:
This one is (mostly) silent, only outputting fatal errors:
MONERO_LOGS=*:FATAL
This one is very verbose:
MONERO_LOGS=*:TRACE
This one is totally silent (logwise):
MONERO_LOGS=""
This one outputs all errors and warnings, except for the
"verify" category, which prints just fatal errors (the verify
category is used for logs about incoming transactions and
blocks, and it is expected that some/many will fail to verify,
hence we don't want the spam):
MONERO_LOGS=*:WARNING,verify:FATAL
Log levels are, in decreasing order of priority:
FATAL, ERROR, WARNING, INFO, DEBUG, TRACE
Subcategories may be added using prefixes and globs. This
example will output net.p2p logs at the TRACE level, but all
other net* logs only at INFO:
MONERO_LOGS=*:ERROR,net*:INFO,net.p2p:TRACE
Logs which are intended for the user (which Monero was using
a lot through epee, but really isn't a nice way to go things)
should use the "global" category. There are a few helper macros
for using this category, eg: MGINFO("this shows up by default")
or MGINFO_RED("this is red"), to try to keep a similar look
and feel for now.
Existing epee log macros still exist, and map to the new log
levels, but since they're used as a "user facing" UI element
as much as a logging system, they often don't map well to log
severities (ie, a log level 0 log may be an error, or may be
something we want the user to see, such as an important info).
In those cases, I tried to use the new macros. In other cases,
I left the existing macros in. When modifying logs, it is
probably best to switch to the new macros with explicit levels.
The --log-level options and set_log commands now also accept
category settings, in addition to the epee style log levels.
