CC upper limits ? BUT for sure BUGs

[killerbot]

Are there any upper limits for CC (parsing ?)  related to :
- number of projects in workspace
- number of files
- number of tokens identified

I have noticed this for a very long time (1 year  + ?), when I load a workspace, which contains +- 100 projects (maybe even more), the CC works very bad. It can't find declarations, implementations, even when the stuff is within the same (active) project, when looking at the log of the parsing, I notice it for sure does not parse all projects.

So lot of frustration with the users :-(

There is a limit for project numbers if you are in "One Parser per Project" case. I don't think there is a limit for the "One Parser for the whole Workspace" case.

Code: [Select]

- number of files
- number of tokens identified
No.

[killerbot]

did some experiment, I noticed already in the past the parsing (in the CB log tab) stopped at the same project in the workspace, it is not due to the fact it is a given Nth project, sicne other projects have been added to the workspace in front of the project where the parsing stopped upon.

First description of the workspace.
- one parser per workspace
- it contains 477 projects
- the log shows the pairs of AddProjectToParser/OnParserEnd, it show 76 pairs and then it ends with AddProjectToParser on the problematic project "FOO"

One thing to note about project FOO : it is a library project with only headers, so when building this project there's nothing to do.

Made this project FOO the active project in the workspace, that means it would become the first project to be parsed, the one which triggers the CreaterParser.
This does make a difference !!!

It is parsed and more projects (starting from the first one in the workspace are being added/parsed).
The results are better, but still extremely bad. Now 228 projects made it through the parsing step. Again it halts on project "BAR".
Special thing about this project "BAR" : it is a library project with only headers.

For further tests I made a workspace with 4 projects, one of them being "FOO" (it was the second one, and the first project being the active), in this case all did get parsed ...
EDIT : an 11 projects workspace containing FOO and BAR, all parsed ...

[ollydbg]

Is it happens when there are some editor opened when you load the workspace?
What happens if you have *NO* editors opened when you load the workspace?
Please test and report back, I suspect that the opened editor cause this issue.


Also, when in one parser for whole workspace mode, the project files will be parsed one another. But the next project will only be triggered if the previous project parsing send an "OnParserEnd" event.

Another guess is that if one Foo project contains some files, but those files were already be parsed before, then in-fact, there is no actual Parserthread tasks assigned to the threadedtask-pool, then, there will be no parser-end event,  because the parser-end event were initially sent from the threaded task pool that all tasks were done.

EDIT: If possible, can you post the debug log messages? Thanks.

// NOTE (Morten#1#): Shouldn't this actually be a temp parser??? I think this screws things with re-opening files on load of a projects...
I agree on this, why do we need to check the editor on the OnParsingOneByOneTimer event? This is basically to parse the project sequentially in one parser for whole workspace mode.

[killerbot]

during the entire tests, no editor was open.

[killerbot]

new test : I create a "DUMMY" project, which cpp file was including the headers that the "FOO" library has, meaning every file of project "FOO" (remember header only) CAN/HAS been seen by the parser.

When DUMMY is after FOO : all ok.
When DUMMY is before FOO, the above mentioned problem pops up, and all parsing stops, the OnParserEnd for "FOO" never happens.

Code: [Select]

NativeParser::AddProjectToParser(): Add project (Dummy) to parser
NativeParser::OnParserEnd(): Project 'Dummy' parsing stage done!

Ok, so it looks like my guess was correct.

Another guess is that if one Foo project contains some files, but those files were already be parsed before, then in-fact, there is no actual Parserthread tasks assigned to the threadedtask-pool, then, there will be no parser-end event,  because the parser-end event were initially sent from the threaded task pool that all tasks were done.

I will see I can take some time to fix this issue.

[ollydbg]

But I can't reproduce this bug here, see my testing workspace with three projects (in attachment).
Can you give me some sample workspace?

     /** Remove cbp from the common parser, this only happens in one parser for whole workspace mode
      * when a parser is removed from the workspace, we should remove the project from the parser


The description of the patch is:

* CC: Fix a bug in the one parser for the whole workspace mode, if a project's file was already parsed by previous projects, then this project don't actually run a parsing tasks (for parsing source files), thus there is not ParserEnd event happened.

The general logic are below:

thread pool done-> send event to Parser object
Parser::OnAllThreadsDone(CodeBlocksEvent& event) -> send a Parser End event
NativeParser::OnParserEnd -> m_TimerParsingOneByOne.Start(500, wxTIMER_ONE_SHOT);
NativeParser::OnParsingOneByOneTimer -> AddProjectToParser(projs->Item(i)); (adding the next project)

But if AddProjectToParser() add nothing to the Task pool, there will be no "thread pool done" again, so all the remaining projects has no chance to be done.

So, I simply let the AddProjectToParser() function return actually added file numbers, if it is zero, we try to parse the next project.
