PKEuS ccf087d2ea checkMathFunctions: Refactoring the check 2011-10-22 12:31:47 +02:00
Thomas Jarosch 55d9f0873a Fix #3243 (Improve non reentrant function check)
- Use std::map instead of linear std::list walk
  and run fast tests like tok->isName() first.

  Global speed up is 4.8% (profiled with google-perftools)

- Catch function invocations in global namespace
  and ignore other namespaces except "std".

  std::localtime() and others are also non-thread safe on POSIX.

  Note: The check matches f.e. also on "std::getrpcbyname()",
  but that would result in a compile error anyway.
  No need to have an extra "std::xxxxx" whitelist.

- Remove double listed "rand" and "getrpcbyname" function names

Benjamin Goose 3f25bd9530 Qualify fill_n properly.
Relying on ADL isn't a good idea as it's not always well implemented.

Edoardo Prezioso 9257e82475 Improve tokenizer: don't confuse between a label and the case/default statements. 2011-10-19 18:49:02 +02:00
Edoardo Prezioso 882b0c15a0 Improve tokenizing of "do{ ... } while(0)".
The simplification will be the same for every combination, except for the 'continue' and the 'break'. In that case, keep the block braces.

Joshua Beck 56561835f8 Add option to set #ifdef configuration check limit 2011-10-18 19:52:55 -05:00
Edoardo Prezioso f4cdf57955 Fixed ticket #3229 (Segfault with goto):
Don't handle labels, gotos, returns and indentations inside the round braces. This is applied not only for simplifyGoto, but also to simplifyFlowControl.
Rewrite enum badly handled by astyle inside mathlib.cpp and move simplifyFlowControl at the end of the simplifyTokenList in order to catch more dead code, not related to the ticket.

Thomas Jarosch 849bee8437 [PATCH] Detect suspicious use of semicolon after 'if/for/while'
statements if they are followed by a {..} block.

Examples are:

{
   printf("i)";
}

or

if (i == 100);
{
   die("Wrong argument");
}

This new check is active if you enable inconclusive checks.

Edoardo Prezioso 9270b84d64 More fixes to the label simplifier (related to ticket 3176):
1)Simplify the labels if there are combinations of the symbols '*','&','{' and '(' after a '%var% :' and before another '%var%';
2)but do not simplify the label if it's inside an unpreprocessed macro code.

Kimmo Varis 3cfe7ca1a7 Move "information" errors to "style" errors.
"information" severity is documented in lib/errorlogger.h as:

  Checking information.
  Information message about the checking (process) itself. These
  messages inform about header files not found etc issues that are
  not errors in the code but something user needs to know.

It IS NOT for errors in the code. All the current "information"-
severity errors fit nicely into description of the "style"-
severity.

We definitely need to separate processing information and actual
errors in the code. It is highly confusing for users to mix these
two different things. Hence all current "information" code error
messages are moved to "style" category.

Ticket: #3165 (Stop misusing the 'information' error severity!)
