Please be consistent with the existing coding style.
|
|
|
|
Block style:
|
|
|
|
bool Function(char* psz, int n)
|
|
{
|
|
// Comment summarising what this section of code does
|
|
for (int i = 0; i < n; i++)
|
|
{
|
|
// When something fails, return early
|
|
if (!Something())
|
|
return false;
|
|
...
|
|
}
|
|
|
|
// Success return is usually at the end
|
|
return true;
|
|
}
|
|
|
|
- ANSI/Allman block style
|
|
- 4 space indenting, no tabs
|
|
- No extra spaces inside parenthesis; please don't do ( this )
|
|
- No space after function names, one space after if, for and while
|
|
|
|
Variable names begin with the type in lowercase, like nSomeVariable.
|
|
Please don't put the first word of the variable name in lowercase like
|
|
someVariable.
|
|
|
|
Common types:
|
|
n integer number: short, unsigned short, int, unsigned int,
|
|
int64, uint64, sometimes char if used as a number
|
|
d double, float
|
|
f flag
|
|
hash uint256
|
|
p pointer or array, one p for each level of indirection
|
|
psz pointer to null terminated string
|
|
str string object
|
|
v vector or similar list objects
|
|
map map or multimap
|
|
set set or multiset

Locking/mutex usage notes
|
|
|
|
The code is multi-threaded, and uses mutexes and the
|
|
CRITICAL_BLOCK/TRY_CRITICAL_BLOCK macros to protect data structures.
|
|
|
|
Deadlocks due to inconsistent lock ordering (thread 1 locks cs_main
|
|
and then cs_wallet, while thread 2 locks them in the opposite order:
|
|
result, deadlock as each waits for the other to release its lock) are
|
|
a problem. Compile with -DDEBUG_LOCKORDER to get lock order
|
|
inconsistencies reported in the debug.log file.
|
|
|
|
Re-architecting the core code so there are better-defined interfaces
|
|
between the various components is a goal, with any necessary locking
|
|
done by the components (e.g. see the self-contained CKeyStore class
|
|
and its cs_KeyStore lock for example).
