Location List Issue - Vim 7.4, patches 1-1707

[amadeus]

I am using the latest version of Vim, built from source, and the location list appears broken when attempting to use it to jump to a location of an error/warning returned from ESLint.

When I press enter on a line in the location list, my cursor just returns to the last position it was in the buffer before I jumped to the location list split.

I also get an error:

E926: Current location list was changed

Not sure if this is an issue Vim needs to fix, or if they changed something with how location lists are handled and Syntastic needs a fix.

Something definitely changed with vim; old versions are working fine. Also lnext and lprev still work, just not selecting from the list.

I haven't seen any vim issues raised on it yet.

Yes, this behaviour was introduced by Vim 7.4.1592, but it isn't clear the bug is in Vim, or that it should be addressed there. The patch 1592 is a bug fix, and it solves a real crash. On the other hand, what syntastic does on the relevant code path is a mess, and it's definitely wrong in some scenarios. I made several attempts over the years to fix this, but the limitations in Vim's API basically mean that fixing some scenario breaks others. Until patch 1592 the broken scenarios were just less common. I'll try again, but I'm not particularly confident the result is going to be substantially better this time. shrug

Duplicate of #1127.

Please try 7e986f1 and report any problems. Segfaults might be on the plate too (well, hopefully not).

I am testing it out, so far it seems to work great, thanks!

Sorry for the late reply -- working flawlessly for me on vim 7.4.1707.

@lcd047 I'm getting this error when opening a file for the first time through the locationlist:

@luan Right, please upgrade to d9814c5.

Not fixed, see the end of #1127 for updates.
