@BlueHazzard, maybe you can check the log files in your system Temp folder to see what content were sent from the clangd.
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

This looks like the crashes during CB shutdown or when closing a file while clangd sent a response to a previous request.
Likely fixed in rev 70.

I see one bug, I'm not sure it is a clangd bug or our client plugin bug.

When I do code refactoring, I mean I want to rename a variable aaa to bbb.

If there is a line:

Quote
wxLogMessage("aaa", aaa);

Then I will get this:

Quote
wxLogMessage("bbb", aaa);

maybe, clangd does not give us the column information of a variable? It just tell use the line information?

Do you mean that the unquoted aaa should have been changed to the unquoted bbb (the second parameter) ?

Yes.
Fixed rev 70

@BlueHazzard, maybe you can check the log files in your system Temp folder to see what content were sent from the clangd.
It could be this two logs, but i am not 100% sure:

@BlueHazzard, maybe you can check the log files in your system Temp folder to see what content were sent from the clangd.

To find a particular clangd_client log, look at the file "CBclangd_LogsIndex.txt" in your temp folder.

Each line contains the processid, the date and time of the log, location of the clangd executable, and the CB project .cbp filename.

The logs are named:
\temp\CBclangd_client-<processID>.log
\temp\CBclangd_server-<processID>.log

The CBclangd_client-<processID>.log is the most interesting for debugging CB.

The CBclangd_client-<processID>.log is useful for probing/debugging clangd and is usually required to submit bug reports to the clangd team.

One log (not so interesting) exists for the CC_ProxyProject.cbp. It handles parsing non-project files.

Two logs for each opened project; The client log and the server log.

The first log line header contains the project it belong to. And the .cbp that created it. the time is on the left.

Edit: 2022/07/31
The log representing a project contains all clangd requests and responses for any file or any target. 
In error, I said that there was a log for each target. Not so.

The crash is still happening with r70,
i can reproduce it now:
1) Open codeblocks
2) Open a project with some code (i used the clang_cc project)
3) Hit recompile as fast as you can after project load, and the cc parser is not finished. compiling will start and in the middle -> crash

backtrace and log content is the same as in my previous posts

I'm having a problem getting the crash.

Would you please copy your devel31_64 version of clangd_client.dll with the debug symbols over the top of your output31_64 version and post the crash .RPT file.

I was not able to re-create the crash, but I got a crash if I close C::B down while compiling which did not occur with the latest nightly.  I close by clicking on the [X] on the top right of the C::B window. This crash does not include any ClangD-cleint functions, but does have event functions  in the stack so there is a very small slim possibility it could be related and this is why I am posting it here just in case I am wrong.

Re: Code completion using LSP and clangd

Hi, Pecan, if possible, can you have several more small svn commits instead of a big svn commit.

I mean I see your commit history(such as rev70), it mainly have several code changes from many places, and the expected way is for each logic code change, you should have a commit. This make the code a bit clean and easy to track.

Thanks.

BTW: The best way is using git, not svn.  :)
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

Hi Pecan,

I' using the ClangdClientForCBNightly_20220813_rev12864_win64.zip with the latest CB nightly and I'm observing a minor issue and a crash. They are present on both Win7 Pro  and Windows 10 Enterprise

The minor issue is related to the option "Update parser when typing )on save otherwise". I de-select this option because I'd like to update just when I'm saving the file. In reality the updating happens both when typing and (instead of otherwise) when saving. May be this is the implemented feature but in some cases the parser updating when typing is a little bit annoying, I think that updating just on saving can be very useful especially when you are typing a new code and several errors appears when I'm correcting them

The crash happens when the window, shown in the attached picture , is present in the editor. CB just freeze and the a crash happen. I'm also attaching the .RPT file related to this crash.

Hope this helps

Max

MaxGaspa, The type of crash in the rpt file has been seen before and Miguel has made some changes a month or two ago that reduced the occurrence of it, but it looks like it is still occurring.  It is my understanding from what I have seen that the problem is not to do with the Clangd_Client plugin, but you just had the dialog up when it crashed.

Just before it crashed were you editing or had some other app (not C::B) in focus?


It looks like it could be the same or similar issue to the crashes as per the following ticket:
https://sourceforge.net/p/codeblocks/tickets/1168

I was editing the related file source file in CB ....

The crash(both reported by MaxGaspa and https://sourceforge.net/p/codeblocks/tickets/1168/) looks like inside the CCManager code:

Code
AddrPC           Params
0000000070CB7861 000000002D1DC710 000000000083EDDC 000000000083EDD8  codeblocks.dll!cbThreadPool::Done

Mainly in the CCManager::OnPopupScroll function.
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

I'm beginning to think this actually is a clangd_client problem.
Clangd_client is using a feature of ccmanager that was never used before. Namely a call to ccmanager::NotifyDocumentation().
CodeCompletion never used it. No other code has ever used it. So this is a path through ccmanager that has previously never been thoroughly test.

I'm working on it.

Edit: 2022/09/13
As it turns out, the problem existed before clangd_client was created.
But clangd_client gets the problem also.
The html documentation popup gets stuck opened (usually by slow double-clicking on a completion selection) and cannot be closed. Using the mouse to focus outside CB then attempting to focus back into CB reveils the stall.
The debugger just shows (for me) "corrupted stack".
But I suspect the stall occurs before focusing outside CB.

Probably because of recent changes in C::B sdk, clangd_client does not compile when using wxWidgets 3.2.1 (probably >= 3.1.6)
Error in client.cpp, line 3672 : CodeBlocksLogEvent waits for a wxBitmapBundle*, but logbmp is a wxBitmap*
Windows 10 64 bits (21H2), svn C::B (last version or almost!), wxWidgets 3.2.1, Msys2 Compilers 12.2.0, 64 bits (seh, posix : gcc, g++ and gfortran in C:\msys64\mingw64) or 32 bits (dwarf2, posix  in C:\msys64\mingw32).
