Integrates the file-watching program Watchman with Mercurial to produce faster
status results.
On a particular Linux system, for a real-world repository with over 400,000
files hosted on ext4, vanilla `hg status` takes 1.3 seconds. On the same
system, with fsmonitor it takes about 0.3 seconds.
fsmonitor requires no configuration -- it will tell Watchman about your
repository as necessary. You'll need to install Watchman from
https://facebook.github.io/watchman/ and make sure it is in your PATH.
fsmonitor is incompatible with the largefiles and eol extensions, and
will disable itself if any of those are active.
The following configuration options exist:
::
[fsmonitor]
mode = {off, on, paranoid}
When `mode = off`, fsmonitor will disable itself (similar to not loading the
extension at all). When `mode = on`, fsmonitor will be enabled (the default).
When `mode = paranoid`, fsmonitor will query both Watchman and the filesystem,
and ensure that the results are consistent.
::
[fsmonitor]
timeout = (float)
A value, in seconds, that determines how long fsmonitor will wait for Watchman
to return results. Defaults to `2.0`.
::
[fsmonitor]
blacklistusers = (list of userids)
A list of usernames for which fsmonitor will disable itself altogether.
::
[fsmonitor]
walk_on_invalidate = (boolean)
Whether or not to walk the whole repo ourselves when our cached state has been
invalidated, for example when Watchman has been restarted or .hgignore rules
have been changed. Walking the repo in that case can result in competing for
I/O with Watchman. For large repos it is recommended to set this value to
false. You may wish to set this to true if you have a very fast filesystem
that can outpace the IPC overhead of getting the result data for the full repo
from Watchman. Defaults to false.
::
[fsmonitor]
warn_when_unused = (boolean)
Whether to print a warning during certain operations when fsmonitor would be
beneficial to performance but isn't enabled.
::
[fsmonitor]
warn_update_file_count = (integer)
If ``warn_when_unused`` is set and fsmonitor isn't enabled, a warning will
be printed during working directory updates if this many files will be
created.
