manifest: persist the manifestfulltext cache
Reconstructing the manifest from the revlog takes time, so much so that there
already is a LRU cache to avoid having to load a manifest multiple times.
This patch persists that LRU cache in the .hg/cache directory, so we can re-use
this cache across hg commands. Commit benchmark (run on Macos 10.13 on a
2017-model Macbook Pro with Core i7 2.9GHz and flash drive), testing without
and with patch run 5 times, baseline is r2a227782e754:
* committing to an existing file, against the mozilla-central repository.
Baseline real time average 1.9692, with patch 1.3786.
A new debugcommand "hg debugmanifestfulltextcache" lets you inspect the cache,
clear it, or add specific manifest nodeids to it. When calling
repo.updatecaches(), the manifest(s) for the working copy parents are added to
the cache.
The hg perfmanifest command has an additional --clear-disk switch to clear this
cache when testing manifest loading performance.
Using this command to test performance on the firefox repository for revision
f947d902ed91, whose manifest has a delta chain length of 60540, we see:
$ hg perfmanifest f947d902ed91 --clear-disk
! wall 0.972253 comb 0.970000 user 0.850000 sys 0.120000 (best of 10)
$ hg debugmanifestfulltextcache -a `hg log --debug -r f947d902ed91 | grep manifest | cut -d: -f3`
Cache contains 1 manifest entries, in order of most to least recent:
id: 0294517df4aad07c70701db43bc7ff24c3ce7dbc, size 25.6 MB
Total cache data size 25.6 MB, on-disk 0 bytes
$ hg perfmanifest f947d902ed91
! wall 0.036748 comb 0.040000 user 0.020000 sys 0.020000 (best of 100)
Worst-case scenario: a manifest text loaded from a single delta; in the firefox
repository manifest node 9a1246ff762e is the chain base for the manifest
attached to revision f947d902ed91. Loading this from a full cache file is just
as fast as without the cache; the extra node ids ensure a big full cache:
$ for node in 9a1246ff762e 1a1922c14a3e 54a31d11a36a 0294517df4aa; do
> hgd debugmanifestfulltextcache -a $node > /dev/null
> done
$ hgd perfmanifest -m 9a1246ff762e
! wall 0.077513 comb 0.080000 user 0.030000 sys 0.050000 (best of 100)
$ hgd perfmanifest -m 9a1246ff762e --clear-disk
! wall 0.078547 comb 0.080000 user 0.070000 sys 0.010000 (best of 100)

$ hg help notify
notify extension - hooks for sending email push notifications
This extension implements hooks to send email notifications when changesets
are sent from or received by the local repository.
First, enable the extension as explained in 'hg help extensions', and register
the hook you want to run. "incoming" and "changegroup" hooks are run when
changesets are received, while "outgoing" hooks are for changesets sent to
another repository:
[hooks]
# one email for each incoming changeset
incoming.notify = python:hgext.notify.hook
# one email for all incoming changesets
changegroup.notify = python:hgext.notify.hook
# one email for all outgoing changesets
outgoing.notify = python:hgext.notify.hook
This registers the hooks. To enable notification, subscribers must be assigned
to repositories. The "[usersubs]" section maps multiple repositories to a
given recipient. The "[reposubs]" section maps multiple recipients to a single
repository:
[usersubs]
# key is subscriber email, value is a comma-separated list of repo patterns
user@host = pattern
[reposubs]
# key is repo pattern, value is a comma-separated list of subscriber emails
pattern = user@host
A "pattern" is a "glob" matching the absolute path to a repository, optionally
combined with a revset expression. A revset expression, if present, is
separated from the glob by a hash. Example:
[reposubs]
*/widgets#branch(release) = qa-team@example.com
This sends to "qa-team@example.com" whenever a changeset on the "release"
branch triggers a notification in any repository ending in "widgets".
In order to place them under direct user management, "[usersubs]" and
"[reposubs]" sections may be placed in a separate "hgrc" file and incorporated
by reference:
[notify]
config = /path/to/subscriptionsfile
Notifications will not be sent until the "notify.test" value is set to
"False"; see below.
Notifications content can be tweaked with the following configuration entries:
notify.test
If "True", print messages to stdout instead of sending them. Default: True.
notify.sources
Space-separated list of change sources. Notifications are activated only
when a changeset's source is in this list. Sources may be:
"serve" changesets received via http or ssh
"pull" changesets received via "hg pull"
"unbundle" changesets received via "hg unbundle"
"push" changesets sent or received via "hg push"
"bundle" changesets sent via "hg unbundle"
Default: serve.
notify.strip
Number of leading slashes to strip from url paths. By default, notifications
reference repositories with their absolute path. "notify.strip" lets you
turn them into relative paths. For example, "notify.strip=3" will change
"/long/path/repository" into "repository". Default: 0.
notify.domain
Default email domain for sender or recipients with no explicit domain.
notify.style
Style file to use when formatting emails.
notify.template
Template to use when formatting emails.
notify.incoming
Template to use when run as an incoming hook, overriding "notify.template".
notify.outgoing
Template to use when run as an outgoing hook, overriding "notify.template".
notify.changegroup
Template to use when running as a changegroup hook, overriding
"notify.template".
notify.maxdiff
Maximum number of diff lines to include in notification email. Set to 0 to
disable the diff, or -1 to include all of it. Default: 300.
notify.maxdiffstat
Maximum number of diffstat lines to include in notification email. Set to -1
to include all of it. Default: -1.
notify.maxsubject
Maximum number of characters in email's subject line. Default: 67.
notify.diffstat
Set to True to include a diffstat before diff content. Default: True.
notify.showfunc
If set, override "diff.showfunc" for the diff content. Default: None.
notify.merge
If True, send notifications for merge changesets. Default: True.
notify.mbox
If set, append mails to this mbox file instead of sending. Default: None.
notify.fromauthor
If set, use the committer of the first changeset in a changegroup for the
"From" field of the notification mail. If not set, take the user from the
pushing repo. Default: False.
If set, the following entries will also be used to customize the
notifications:
email.from
Email "From" address to use if none can be found in the generated email
content.
web.baseurl
Root repository URL to combine with repository paths when making references.
See also "notify.strip".
