ui: remove commands.status.terse=u from ui.tweakdefaults...
ui: remove commands.status.terse=u from ui.tweakdefaults commands.status.terse=u can add significant overhead when operating on large repositories. Using the Firefox repository: HGRCPATH= hg --time status time: real 1.340 secs (user 0.960+0.000 sys 0.380+0.000) HGRCPATH= hg --time --config commands.status.terse=u status time: real 2.420 secs (user 2.070+0.000 sys 0.360+0.000) HGRCPATH= hg --time --config extensions.fsmonitor= status time: real 0.080 secs (user 0.050+0.010 sys 0.040+0.000) HGRCPATH= ~/src/hg/hg --time --config extensions.fsmonitor= --config commands.status.terse=u status time: real 2.470 secs (user 2.080+0.000 sys 0.390+0.000) The performance regression - especially when fsmonitor is being used - is too much to stomach for the 4.7 release. We've decided to remove commands.status.terse=u from ui.tweakdefaults until we can improve its performance, hopefully in the 4.8 cycle. This commit effectively backs out 6acf41bb8d40.

How to add fuzzers (partially cribbed from oss-fuzz[0]):

  1. git clone https://github.com/google/oss-fuzz
  2. cd oss-fuzz
  3. python infra/helper.py build_image mercurial
  4. docker run --cap-add=SYS_PTRACE -it -v $HG_REPO_PATH:/hg-new
    gcr.io/oss-fuzz/mercurial bash
  5. cd /src
  6. rm -r mercurial
  7. ln -s /hg-new mercurial
  8. cd mercurial
  9. compile
  10. ls $OUT

Step 9 is literally running the command "compile", which is part of the docker container. Once you have that working, you can build the fuzzers like this (in the oss-fuzz repo):

python infra/helper.py build_fuzzers --sanitizer address mercurial $HG_REPO_PATH

(you can also say "memory", "undefined" or "coverage" for sanitizer). Then run the built fuzzers like this:

python infra/helper.py run_fuzzer mercurial -- $FUZZER
