Summary: `hg purge --dirs` is slow because it asks for all the directories in the repo, which disables the fsmonitor speed improvements to dirstate.walk. To make purge faster, separately query watchman for all the dirs in the repo (it can answer this fairly quickly).

'''removes files not tracked by Mercurial
|
|
|
|
Delete files not known to Mercurial. This is useful to test local
|
|
and uncommitted changes in an otherwise-clean source tree.
|
|
|
|
This means that purge will delete the following by default:
|
|
|
|
- Unknown files: files marked with "?" by :hg:`status`
|
|
- Empty directories: in fact Mercurial ignores directories unless
|
|
they contain files under source control management
|
|
|
|
But it will leave untouched:
|
|
|
|
- Modified and unmodified tracked files
|
|
- Ignored files (unless --all is specified)
|
|
- New files added to the repository (with :hg:`add`)
|
|
|
|
The --files and --dirs options can be used to direct purge to delete
|
|
only files, only directories, or both. If neither option is given,
|
|
both will be deleted.
|
|
|
|
If directories are given on the command line, only files in these
|
|
directories are considered.
|
|
|
|
Be careful with purge, as you could irreversibly delete some files
|
|
you forgot to add to the repository. If you only want to print the
|
|
list of files that this program would delete, use the --print
|
|
option.
