## Verify dsymutil bumps the .dSYM bundle directory's mtime when rewriting an
## existing bundle in place. macOS Spotlight keys off this mtime to decide
## whether to reimport the bundle's UUID; without the bump, Spotlight serves
## the previous build's UUID and DebugSymbols falls through to slow
## dsymForUUID lookups.

RUN: rm -rf %t.dir
RUN: mkdir -p %t.dir
RUN: cat %p/../Inputs/basic.macho.x86_64 > %t.dir/basic
RUN: dsymutil -oso-prepend-path=%p/.. %t.dir/basic

## Backdate the bundle dir to a known epoch so any update is visible.
RUN: env TZ=GMT touch -t 197001020000 %t.dir/basic.dSYM
## Marker with a newer-than-backdated timestamp; the second dsymutil run
## must move the bundle dir's mtime past this marker.
RUN: env TZ=GMT touch -t 200001010000 %t.dir/marker

RUN: dsymutil -oso-prepend-path=%p/.. %t.dir/basic

## `find -maxdepth 0 -newer` prints the bundle path iff its mtime is newer
## than the marker. Without the mtime bump, the directory keeps its 1970
## stamp and find prints nothing.
RUN: find %t.dir/basic.dSYM -maxdepth 0 -newer %t.dir/marker | FileCheck %s
