Fully cleaning a changeset

[Michael Buchoff]

As part of our automated build process, we want to undo all changes and delete all added files (ignored and hidden) before building so that we're starting from a completely clean changeset.  We've experimented with various cm.exe options, but haven't found any combination that does what we're trying to do.

As a workaround, we typically delete the entire directory (with rmdir /s /q) and check it back out, but occasionally the directory doesn't delete successfully; one of the background processes such as an antivirus or plasticscmshellextensionproxy.exe probably has lock on it.

What's the preferred way to completely clean a changeset?

Thanks in advance.

Hi Michael,

Let me know if this helps:

Wow, thanks for the fast response!

When I tried cm unco --all, it undid all my changes, but didn't delete all the private, hidden, and ignored files.  When typing cm unco --help, the help text doesn't mention the --all switch, so maybe there's a way to ask for this as well?

Edit:  cm version tells me I'm running 6.0.16.1765.

Just wanted to bump here.  Does anyone know a way to fully clean a Plastic revision, including unversioned files?

Hi @Michael Buchoff,

I'm afraid plastic will never delete your private files but you can search them and get rid of them.

For ignored private files you can do the following:

@echo off
    setlocal enableextensions disabledelayedexpansion

    for /f "delims=" %%a in ('cm status --private --short') do del /q "%%a"

Yes, a little tricky since the del command can't be piped (AFIK).

You can combine the ignore and private search by using the two flags at once: --ignored --private

Hope it helps!

So we finally got around to applying the script above and it seems to almost work.  There's a delay of a few minutes, followed by a long list of del command deleting the ignored files/directories.  Unfortunately, the final del command is:

del /q "Finding changed files took too long. Perf tips: https://www.plasticscm.com/download/help/statusperfhintschanged"

 

Apparently, there's a built-in time limit for the cm status command to run.  Is there an option to turn that time limit off?

Hello @Michael Buchoff,

yes! you can turn it off by running the status command with the "--machinereadable" parameter.

cm status --private --short --machinereadable

hope it helps!

This is what i use

IFS=$'\n'; for OUTPUT in $(cm status --fp --short --compact); do rm -R "$OUTPUT"; done;

In case it helps anyone, there's a flag

--cutignored

that can be combined with

--ignored

to filter out the contents below ignored directories, thereby simplifying the output. The following command gives a list that can be used directly in a FOR loop :

cm status --ignored --cutignored --compact --short
