Failed to open /path/to/cache/0/symnames #703

Closed dscole closed 8 years ago

dscole commented 8 years ago

I've been having these issues for a while and finally decided to try and track down what is going on. I just loaded up a large database of ~ 6120 source files. Now I try to run rtags-find-symbol on some constructor and it fails. Emacs' message is "RTags: No results" and when I look at the rdm log I see these errors:

/path/to/rc --current-file=/path/to/file_name.h --no-color -f /path/to/file_name.h:35:3:

Any ideas what's going on?

The only thing I can think of is that during the long loading time of the database, I might have tried to query that symbol before the relevant file was parsed.

I don't know what caused this, but restarting the rdm server and triggering a recompilation on the relevant header file (by changing a whitespace and saving the file) made this go away. I'll reopen if this comes up again.

Andersbakken commented 8 years ago

It happens for me sometimes too and I haven't been able to find a good repro for it. If you're able to I'd love to hear about it.

Same here, it frequently makes rtags unusable on a rather big project, but I could never reproduce it on smaller scale.

dscole commented 8 years ago

I'm currently running the rdm server gdb with a breakpoint at: 342 B *errPtr = "Failed to open: " + path + " " + Location::path(fileId) + ": " + err; and: 344 B error() << "Failed to open" << path << Location::path(fileId) << err;

In the hopes of catching this in the act.

@Andersbakken , do you mind giving a quick explanation of what is supposed to be specifically in the directory '0'? Also, I'm trying to confirm how the rtags database works, so please correct me if I'm wrong. The way I understand it, somewhere (in _project_name_/sources?) there is a map <file_name.cpp> -> <index>. Each index represents a directory _project_name_/<index>/ which holds all the information for that specific <file_name.cpp>. One thing I don't understand is why I have 19084 directories in _project_name_/ when I only loaded about 6000 targets.

Hi

the number corresponds to a file id and 0 is meant to be invalid so this shouldn't really be possible.

The reason you have more dirs than source files is that the headers get a directory each too.

Let me know if you catch it. I've been meaning to do something similar but I can't seem to really get it to happen with any sort of reliability.

That is quite useful. It seems to imply to me that there's a node with fileId 0 in the mDependencies. Not sure if you still have gdb open but if you do. Any chance you could see if you could get to the value (type DependencyNode *) for the key: 0 in project->mDependencies.

If you can, it would be nice to know if its fileId matches the key (e.g. if it is 0) and if it has any dependents or includes. I've added an additional assert that tries to catch this but more likely the bug happened at an earlier stage. I will try to add additional asserts to catch when this might have happened.

Thanks. I am 99% sure I figured out what happened now. The latest version should have it fixed. Note that you may have to blow away your data directory to reap the benefits.

Ah . I just took that warning out. It's not really useful I guess.
