Bug ID: 44710
Summary: Disable mmap for source files that change under us
Product: clang-tools-extra
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: clangd
Assignee: unassignedclangb...@nondot.org
Reporter: sammcc...@google.com
CC: llvm-bugs@lists.llvm.org
b500c49cd4f81f067cda721049cb1fd72a5e7bf5 turns off mmap for source files in
clangd. SourceManager has a habit of crashing when the data changes from under
it, most often when switching git branches.
This is a fairly safe change and eliminates a common crasher, and we've been
shipping this on windows for a while already. We should merge it into 10.x
