This lets us greatly simply acquire/release cycles.
Code pattern before:
try:
lock = repo.lock()
# zillions of lines of code
finally:
lock.release()
And after:
with repo.lock():
# ...
This extension is copied from
https://bitbucket.org/yuja/chg/ -r 86feb5f2e971
It could be imported as mercurial/chgserver.py, but in that case, we would
have to resolve circular import between chgserver and commandserver. So I
decided to keep it as an extension.
chgserver.chgcmdserver -> commandserver.server
commandserver._servicemap -> chgserver.chgunixservice
Inhibit, one of evolve's extension, would like to change the way rebase works
with obsolete changesets. During a rebase with inhibit, the inhibition of the
obsolescence markers should be lifted for the rebase.
With this small refactoring, inhibit and can wrap the _filterobsoleterevs
function to lift inhibition cleanly and at the same time this change makes
rebases' code more legible.
On Solaris, when you try to mv a file to another path that is a hardlink to
the original, it complains that they're identical. GNU mv doesn't
complain, but it's simpler to just remove the original file instead.
This patch makes _computeobsoleteset much faster by looping
over the draft and secrets as opposed to looping over the
successors.
This works because "number of draft and secret" is typically
way smaller(<100) than the number of successor in the repo (~90k in
my checkout of core mercurial as of today). And also because
it is very fast to compute "not public()".
I timed the code with the following setup:
"""
from mercurial import hg, ui, obsolete
ui = ui.ui()
repo = hg.repository(ui, "~/hg")
l = repo.obsstore.successors # This caches the result
"""
With about 90k successors.
k=obsolete._computeobsoleteset(repo) before this patch:
10 loops, best of 3: 33.9 ms per loop
k=obsolete._computeobsoleteset(repo) after this patch:
10000 loops, best of 3: 83.3 µs per loop
The old code did not understand the difference between the first line of the summary,
and a random line in the summary that happened to include a #, or a
random line in the changes that happened to include it.
7c3798ffdc0c is an example where it fails
