revlog: use mmap by default is pre-population is available...
revlog: use mmap by default is pre-population is available Using mmap has a great impact of memory usage on server, and a good impact on performance in multiple case. Now that we pre-populate memory mapping by default, there is case where it using mmap is slower. So we use it by default (if pre-population is available). Further work to reduce the performance impact of the pre-population will be done later. Some benchmark below (using the same setup as 522b4d729e89): As for 522b4d729e89 the impact on small repository like Mercurial or Pypy is tiny, ~1% best. However for large repositories we see some performance improvement without seeing the performance regression that we could have without pre-populate. ##### For netbeans ### data-env-vars.name = netbeans-2018-08-01-zstd-sparse-revlog ## benchmark.name = hg.command.log # bin-env-vars.hg.flavor = rust # benchmark.variants.limit-rev = 1 # benchmark.variants.patch = yes no-mmap: 0.171579 mmap: 0.166311 (-3.07%, -0.01) # bin-env-vars.hg.flavor = default no-mmap: 0.170716 mmap: 0.165218 (-3.22%, -0.01) # benchmark.variants.patch = no # benchmark.variants.rev = tip no-mmap: 0.140862 mmap: 0.137566 (-2.34%, -0.00) ## benchmark.name = hg.command.unbundle # bin-env-vars.hg.flavor = rust # benchmark.variants.issue6528 = disabled # benchmark.variants.reuse-external-delta-parent = yes # benchmark.variants.revs = any-1-extra-rev # benchmark.variants.source = unbundle no-mmap: 0.238038 mmap: 0.239912 no-populate: 0.cbd4c9 (+11.71%, +0.03) #### For Mozilla ### data-env-vars.name = mozilla-try-2019-02-18-ds2-pnm # benchmark.name = hg.command.log # bin-env-vars.hg.flavor = rust # bin-env-vars.hg.py-re2-module = default # benchmark.variants.limit-rev = 1 # benchmark.variants.patch = yes no-mmap: 0.258440 mmap: 0.237813 (-7.98%, -0.02) # benchmark.variants.limit-rev = 10 no-mmap: 1.235323 mmap: 1.213578 (-1.76%, -0.02) ## benchmark.name = hg.command.push # bin-env-vars.hg.flavor = rust # bin-env-vars.hg.py-re2-module = default # benchmark.variants.explicit-rev = none # benchmark.variants.issue6528 = disabled # benchmark.variants.protocol = ssh # benchmark.variants.reuse-external-delta-parent = yes # benchmark.variants.revs = any-1-extra-rev no-mmap: 4.790135 mmap: 4.668971 (-2.53%, -0.12) no-populate: 4.841141 (+1.06%, +0.05) ### data-env-vars.name = mozilla-try-2019-02-18-zstd-sparse-revlog ## benchmark.name = hg.command.log # bin-env-vars.hg.flavor = default # benchmark.variants.limit-rev = 1000 # benchmark.variants.rev = tip no-mmap: 0.206187 mmap: 0.197348 (-4.29%, -0.01) ## benchmark.name = hg.command.push # bin-env-vars.hg.flavor = default # benchmark.variants.explicit-rev = none # benchmark.variants.issue6528 = disabled # benchmark.variants.protocol = ssh # benchmark.variants.reuse-external-delta-parent = yes # benchmark.variants.revs = any-1-extra-rev no-mmap: 4.768259 mmap: 4.798632 no-populate: 4.953295 (+3.88%, +0.19) # benchmark.variants.revs = any-100-extra-rev no-mmap: 4.785946 mmap: 4.903618 no-populate: 5.014963 (+4.79%, +0.23) ## benchmark.name = hg.command.unbundle # bin-env-vars.hg.flavor = default # benchmark.variants.issue6528 = disabled # benchmark.variants.reuse-external-delta-parent = yes # benchmark.variants.revs = any-1-extra-rev # benchmark.variants.source = unbundle no-mmap: 1.400121 mmap: 1.423411 no-populate: 1.585365 (+13.23%, +0.19)

"""changeset_obsoleted is a hook to send a mail when an
existing draft changeset is obsoleted by an obsmarker without successor.
Correct message threading requires the same messageidseed to be used for both
the original notification and the new mail.
Usage:
[notify]
messageidseed = myseed
[hooks]
