"""allows users to have JSON progress bar information written to a path
|
|
|
|
Controlled by the `ui.progressfile` config. Mercurial will overwrite this file
|
|
each time the progress bar is updated. It is not affected by HGPLAIN since it
|
|
does not write to stdout.
|
|
|
|
The schema of this file is (JSON):
|
|
|
|
- topics: array of topics from oldest to newest. (last is always the active one)
|
|
- state: map of topic names to objects with keys:
|
|
- topic (e.g. "changesets", "manifests")
|
|
- pos: which item number out of <total> we're processing
|
|
- total: total number of items (can change!)
|
|
- unit: name of the type of unit being processed (e.g., "changeset")
|
|
- item: the active item being processed (e.g., "changeset #5")
|
|
- active: whether this is the currently active progress bar
|
|
- units_per_sec: if active, how many <unit>s per sec we're processing
|
|
- speed_str: if active, a human-readable string of how many <unit>s per sec
|
|
we're processing
|
|
- estimate_sec: an estimate of how much time is left, in seconds
|
|
- estimate_str: if active, a human-readable string estimate of how much time
|
|
is left (e.g. "2m30s")
|
|
|
|
config example::
|
|
|
|
[progress]
|
|
# Where to write progress information
|
|
statefile = /some/path/to/file
|
|
# Append to the progress file, rather than replace
|
|
statefileappend = true
|
|
# Set pid to a fixed value for testing purpose
|
|
fakedpid = 42
