different exit value depending on error

[teto]

I am using the vim-rtags plugin, and I wonder if 'rc' could return different exit values depending on the error, to help the plugin act appropriately. For instance, the plugin runs: rc --absolute-path -U src/nvim/screen.c:1687:15 which returns Not indexed. I would like the plugin to propose the creation of a project or at least explain why the call failed.

I could parse Not indexed but what if the string changes ? or get translated ? acting on exit values seem more robust.

Sorry about the long delay. I've been a little swamped.

What an excellent idea!

I just implemented it.

The error codes are here:

Success = 0,
GeneralFailure = 32,
NetworkFailure = 33,
TimeoutFailure = 34,
NotIndexed = 35,
ConnectionFailure = 36,
ProtocolFailure = 37,
ArgumentParseError = 38,
UnexpectedMessageError = 39,
UnknownMessageError = 40

I will try my hardest not to change them. You probably don't need to act differently on the majority of these but feel free to shoot me any question you might have about which ones occur when.

Thanks.

What are the causes of error 32? When I try to run rc, I get no results, and an exit status 32.

What does rdm say when you start it with '-vvv'?

@hessryanm Hmm, whats inside the log file?

[hessryanm]

@cslux I'm not sure what you mean. The actual RDM process itself doesn't output anything, despite the -vvv. The log only contains that line I put - basically it lists the command it was given.

[casch-at]

--log-file=/usr/local/var/log/rtags.log?

[hessryanm]

yep I'm running tail -f /usr/local/var/log/rtags.log. The only line that appears when I run the rc command is "/usr/local/bin/rc --absolute-path -f /Users/ryanhess/Code/adobe/axle/oberon/xml-handlers/reports.cpp:552:47"

[casch-at]

Can you post a step by step instruction what you have done please?

Also try this please.

rdm -vvv
rc -c gcc -c <(echo 'main(){}')

rdm should output something like that:

Source::parse ( gcc -c /dev/fd/63 ) => List<String>(gcc, -c, /dev/fd/63) /home/cschwarzgruber/

[hessryanm]

When running the way you said, pretty sure I got the same thing: /usr/local/Cellar/rtags/2.31/bin/rdm -vvv

When I run an actual rc command, however, the logs spit out some errors (when running with -vvv):

/usr/local/Cellar/rtags/2.31/bin/rc --absolute-path -f /Users/ryanhess/Code/adobe/axle/oberon/xml-handlers/reports.cpp:1043:21

It looks like the "Failed to open /Users/ryanhess/.cache/rtags/%2FUsers%2Fryanhess%2FCode%2Fadobe%2Faxle%2F/3822/symbols No such file or directory (2) 128" is the repeatable part of the issue.

Please wipe/move the cache away and reparse the project with verbose logging enabled.

[hessryanm]

Log file is too big to attach here. I uploaded it on google drive: https://drive.google.com/open?id=1NOH81SsKU4H6EcMezHoFIVVqH8abJHqx

[casch-at]

Hmm, you could try the --enable-compiler-manager flag, your includes seem to be messed up. Can you post one or two compile commands from the compile_commands.json. You are on MacOS? Is this an opensource project.

Also pleases reparse, it with just one or two compile commands but verbose logging turned on like requested already.

rdm -vv --enable-compiler-manager

Unfortunately we aren't using cmake, we're using some weird ancient custom make extension, and we can't generate compile_commands.json.

I am on OS X, and the project is not open-source.

Here's a minimal log file.
