"""
@type workdir: string
@param workdir: local directory (relative to the Builder's root)
where the tree should be placed
@type mode: string
@param mode: the kind of VC operation that is desired:
- 'update': specifies that the checkout/update should be
performed directly into the workdir. Each build is performed
in the same directory, allowing for incremental builds. This
minimizes disk space, bandwidth, and CPU time. However, it
may encounter problems if the build process does not handle
dependencies properly (if you must sometimes do a 'clean
build' to make sure everything gets compiled), or if source
files are deleted but generated files can influence test
behavior (e.g. python's .pyc files), or when source
directories are deleted but generated files prevent CVS from
removing them. When used with a patched checkout, from a
previous buildbot try for instance, it will try to "revert"
the changes first and will do a clobber if it is unable to
get a clean checkout. The behavior is SCM-dependent.
- 'copy': specifies that the source-controlled workspace
should be maintained in a separate directory (called the
'copydir'), using checkout or update as necessary. For each
build, a new workdir is created with a copy of the source
tree (rm -rf workdir; cp -R -P -p copydir workdir). This
doubles the disk space required, but keeps the bandwidth low
(update instead of a full checkout). A full 'clean' build
is performed each time. This avoids any generated-file
build problems, but is still occasionally vulnerable to
problems such as a CVS repository being manually rearranged
(causing CVS errors on update) which are not an issue with
a full checkout.
- 'clobber': specifies that the working directory should be
deleted each time, necessitating a full checkout for each
build. This insures a clean build off a complete checkout,
avoiding any of the problems described above, but is
bandwidth intensive, as the whole source tree must be
pulled down for each build.
- 'export': is like 'clobber', except that e.g. the 'cvs
export' command is used to create the working directory.
This command removes all VC metadata files (the
CVS/.svn/{arch} directories) from the tree, which is
sometimes useful for creating source tarballs (to avoid
including the metadata in the tar file). Not all VC systems
support export.
@type alwaysUseLatest: boolean
@param alwaysUseLatest: whether to always update to the most
recent available sources for this build.
Normally the Source step asks its Build for a list of all
Changes that are supposed to go into the build, then computes a
'source stamp' (revision number or timestamp) that will cause
exactly that set of changes to be present in the checked out
tree. This is turned into, e.g., 'cvs update -D timestamp', or
'svn update -r revnum'. If alwaysUseLatest=True, bypass this
computation and always update to the latest available sources
for each build.
The source stamp helps avoid a race condition in which someone
commits a change after the master has decided to start a build
but before the slave finishes checking out the sources. At best
this results in a build which contains more changes than the
buildmaster thinks it has (possibly resulting in the wrong
person taking the blame for any problems that result), at worst
is can result in an incoherent set of sources (splitting a
non-atomic commit) which may not build at all.
@type retry: tuple of ints (delay, repeats) (or None)
@param retry: if provided, VC update failures are re-attempted up
to REPEATS times, with DELAY seconds between each
attempt. Some users have slaves with poor connectivity
to their VC repository, and they say that up to 80% of
their build failures are due to transient network
failures that could be handled by simply retrying a
couple times.

This login is only needed once, but must be run
each time (just before the CVS operation) because

defaults to exactly half of the parent
