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 |
|
LOCK/TRY_LOCK 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). |
