V00-22-01 back on top.

Revert back to V00-21-08.

Allow root installation if file /etc/cms-root-install-allowed is present.

Forgot to delete one line.

Avoid race condition which happens when two cmsBuild are invoked on top of the same work-dir.

* This used to happen because tmp dir was being deleted before checking
  that no one else was running there.

remove debug statement

allow . in path but not as a first char on the dir name

Add dummy final job.

* This job is dependent from any other task being scheduled and will
  therefore always be scheduled last. This is useful to avoid dead-lock
  situations because it forces all threads to remain active until all
  the tasks have terminated.
* Unit tests updated accordingly.

Remove obsolete upload code.

based on 1.518: added uploadport for ssh used by rsync, used uploadUser instead of hardcoded cmsbuild, add Acquire::http::No-Cache=true and Acquire::http::Pipeline-Depth=0 for apt-get update to avoid server side caching

same as rev 1.517 i.e V00-20 series plus: fix the comp driver name, drop simplify.sh and mark old style user temp directory as deletable

same as 1.515: sync back latest dev of V00-20 series

calculate child hash locally; rename uploadNew to be upload; For now it will not allow to upload to comp

unify the subsystem names

based on rev 1.509: create top level BUILDROOT to avoid bug https://its.cern.ch/jira/browse/CMSSDT-68

CMSSDT-76 Issue: based on V00-20-35: properly lock locally build rpm instalations commands.

based on V00-20-34: set ignore_compile_errors for new scheduler too

based on 1.503: Fixes new-scheduler for BuildRequires

Based on V00-20-32 rev 1.489: set CVSROOT for TC checkouts

Actually copy files WEB directory for upload...

Allow for a web area to be uploaded in parallel to the usual RPM repository.

Better way to support packages which use the same sources.

Support the case in which we upload two packages sharing the same sources.

* E.g. FWLite and CMSSW.

Introduce a new uploadNew command which can be used to do atomic uploads.

* Automatically migrates old style repositories to new style.
* Add versioning to repository for easy roll back.
* Atomic transactions. When two transactions they either both fail to
  commit or the first one which arrives wins, with the other one starting
  from scratch.
* Deliberately refuse to work when used with cms and comp repositories.
* Can be used together with old style uploads, if needed (manual syncrhonization
  needed in that case).

Use cmspm from cmsdist, if available.

Use the cmspm in CMSDIST if found.

Go back to use CMSSW rather than CMSSW.admin to checkout from CVS.

Fix CVSROOT.

* Now that we have migrated to the new CVSROOT which does not have locking
  issues, we go back to the official CMSSW reposiotory so that we can
  get rid of the CMSSW.admin hack.

same as 1.481: sync back the latest dev in to CVS head

bug fixed: install buildrequires of dependent packages too

based on V00-19-06: back ported checking of local/server packages fix from V00-20-26

fixed regexp for SpecChecksum and checking of packages on Server and local

V00-20-23 back on top.

V00-16-05-19  back on top.

V00-20-22 back on top.

add conditional support for subpackages

sync back latest dev: V00-20

pass cvsroot to cmspm

based on 1.460 i.e V00-16: check if svn scheme already contains svn+

based on rev 1.459 i.e. V00-20: -a option is no more available for cmspm as we pass -d cvsroot instead

Make cmspm behave like CVS.

* -d option added to specify CVSROOT. Default is $CVSROOT.
* cmsBuild adapted to pass the CVSROOT it knows about, this way
  we have only one single place where this is defined.
* cmsBuild uses CVS_PASSFILE to avoid cvs login also when downloading
  using tag collector.

Initial version of the new build task scheduler.

* Completely independent from the old one. Enable by passing --new-scheduler
  when invoking cmsBuild. Old one will be removed once we are happy with
  the new one.
* Download sources of different packages in parallel, while other packages
  are building.
* Build everything which can be build and complain about packages which cannot
  be built, all of them, only at the end.
* Based on Scheduler.py.

added implementation of die function

based on 1.443 i.e. V00-16: back ported cmspm usage, subpackage, svn download etc. from V00-20 release cycle in to V00-16

Use cmspm in place of PackageManagement.pl

Misc fixes.

* Drop --ignore-tag-collector-errors flag.
* Syntactic sugar for "cmstc:" url.

Drop debug message.

Drop question mark from arguments.

cleanup for V00-16based on 1.441: remove a test statement

based on 1.436 i.e. V00-16: sync latest git/svn download changes and workdir lock changes. added %clean section to avoid rpm cleaning up the buildroot

Improved "Source" url handling.

* Support format of the kind:

     git+https://
     svn+ssh://

  to download using git / svn with a different protocol than their native one.
* Support for:

     git://foo.git?obj=branch/tag

  to simplify specification of branch and tag of a git repository.

Based on V00-20-10: (a) do not try to build packages which are already installed. (b) refresh rpm cache after each command-line package is build

based on 1.433: (a) RPM query run once to get the install packages, define cmsos and cmscompilerv via rpmbuild which avoids running of cmsos.file for each cmsplatf in spec file. use 1.35 or above of CMSDIST/rpm-preamle.file to benefit from this

Enormously speed up initialization time.

* Do apt-cache search only once in the beginning, and cache results for later
  usage.
* Drop a now unneeded intermediate save of spec files.

fixed for --no-bootstrap option

sync back V00-20-07 changes: pus set the max macro value liit to 8000 chars

based on 1.425: support for BuildRequires added, for now at build time cmsBuild is going to download/install full dependency i.e. Requires+BuildRequires but using raw apr-get/rpm will only install Requires

Misc cleanups.

* Working git support for downloading sources.
* Allow work dirs to be called "something.app" to create standalone macosx
  application.

split require macros in smaller parts to avoid rpm macro buffer limit

sync back latest dev of V00-20

sync back latest dev of V00-20 release series

based on V00-20-00: sync back latest dev plus fix for Description in package name and RPM 4.4 %post section bug

HEAD is back to be the latest greatest (V00-20).

V00-19-04 back on top.

Forward porting changes between 1.408 and 1.409 to HEAD.

Avoid issues with missing / mixed apt-get environment.

There was a bug which was preventing "apt-get update" to happen after an area
was bootstrapped and it failed silently. Moreover, whenever one builds a new
version of the bootstrap kit, there could be problems if the two rpm are not
compatible.

The new workflow for bootstrapping is as follow:

* Check if there is a link to apt init.sh in <workdir>/<architecture>/apt-init.sh
* If there is not, bootstrap the area and create such a link.
* Source the apt environment from that link.
* Invoke apt-get update.

This guarantees that apt-get update is always invoked with an apt installation
present and guarantees that the only apt used to build packages is the one
which was used at bootstrap time.

This means we can drop the whole logic to detect the most recent version of
apt as well. The --force-apt-version option is also dropped.

If a build area was bootstrapped with an old version of cmsBuild, it will
create the link to the apt installation. Upgrades from old build areas with two
different versions of apt in it is not supported and you'll have to create the
link by hand.

Fix typo.

ported back the buildroot changes in V00-16-05 series

for cms repository, always build with /opt/cmssw as prefix. Build will be done under <workDir>/tmp/BUILDROOT/<checksum>/opt/cmssw: for this please do not forget to include rev 1.31 of CMSDIST/rpm-preamble.file

Copy bootstrap.sh to presonal repository when uploading.

sync back the latest changes from Giulio plus fixes for tmpdir and special workdir /opt/cmssw

Add a "then" that got lost in one of the init.csh reshuffling a while ago.

Misc fixes.

* Correct message when using the wrong architecture flag (e.g. osx* on linux).
* Check for rpm before using it for anything. Die with sensible message if not found.
* Always remove .a and .la files in the post %install part. Define %keep_archives
  to be non null in order to keep them (required for generators).
* Always remove pkgconfig directory, unless keep_pkgconfig macro is defined.
* Remove files / directories found in the %drop_files macro. This allows to
  clean up packages, without having to specify a custom install section.
* Strip files found in the %strip_files macro. This allows stripping
  packages without having to specify a custom install section. It also handles
  differences between mac and linux (strip -x vs strip).

Remove extra 'self.' in getCommandPrefix().

Drop ancient support for python2.3.

Misc fixes for supporting non-system compilers on macosx.

* Remove unused code.
* Propagate correctly the choice of not using the system compiler.

cleanup: removed _ONLINE hack, remove CVs directories using python for patch releases

Based on V00-16-05-04: call PackageManagement.pl with --export so that we do not get CVS directories in src

Fix error message.

* When detecting a broken link, print the full path, not just the part
  relative to the workdir.

Only insert existing directories into paths.

Only set one of LD_LIBRARY_PATH, DYLD_FALLBACK_LIBRARY_PATH.

sync back latest changes plus new bug fix

Show . every second if --progress option is specified.

stop processing if SCRAMRT_SET i.e. scram runtime env is set. stop building is PackageManagement.pl script exit with non zero code (this change was somehow dropped

marged bug fix for V00-16-05-01: allow -NNN, where N is digit in the version string. cmsBuild was suppose to allow this but due to the bug it was not but now fixed.

Clean up CVS files in checkout via python, rather than via bash.

Schedule subpackages for upload.

Better detection of running on linux.

Spring cleaning.

* Now only two workflows are supported:

      cmsBuild [<common options>] -c <cmsdist> -a <architecture> build <packages>
      cmsBuild [<common options>] -c <cmsdist> -a <architecture> upload <packages>

  Notice that upload implies build and that  an additional `--no-bootstrap`
  option can be provided to create the bootstrap kit on new architectures.
* Redundant and unneeded options removed, in particular --test-tag is always
  false and --tag is now the same as repository.
* Improved --help.

For more information refer to the hypernews thread:

https://hypernews.cern.ch/HyperNews/CMS/get/sw-develtools/1353.html

Sort dependencies when printing them out.

Improved behavior of TagCacheAptImpl.requestTag.

Andrea Bocci was complaining that without --names-only a package also matches
subpackages. This then breaks because subpackages don't have a SpecChecksum
(which is actually wrong) and the logic fails.
While more investigation should be done, this seems to me harmless.

revert to 1.351, plus documentation only changes from 1.352, plus fixes from 1.354

sync back with 1.354

based on 1.352 - hopefully fix dependency checking together with "appendRevision"

cmsBuild now stop when PackageManagement.pl script exit with non-zero code

fix regular expression to detect 32-on-64 build for online architectures

Allow site specific spec files.

* `--site <site-name>` option (or similar `site` configuration variable) added.
  If specified, when looking up for dependencies cmsBuild will prefer
  `<site-name>-tool.spec` to `tool.spec`, if the former exists.
  This can be used to specify special configuration for sites or, for example
  for online, where some of the tools have to be picked up from the system.
  The advantage compared to now is that special cases in *dependent* tools will
  not be needed anymore.

Better error message when a package fails (no empty lines anymore).

Misc improvements for building on mac.

* Reduce the artificial delay between building two different packages from
  1s to 0.1s. I should really implement a real scheduler at some point.
* When parsing the spec line header, first do an echo so that things like
  `date +%Y%m%d` can be used to specify a version. This is handy for stuff
  like IB.
* Set LANG=C to avoid locale related issues when parsing output of
  various commands.
* Use a more standard set of options when using "file" to determine file type
  in the macosx %install postamble.
* Exclude .pyc files by hand from install_name relocation procedures.

Remove creation of temporary git repositories.

fix BuildPackage.doDryRun() to properly take into acount subpackages

create cache symlinks for subpackages, too

explicitly set CMS_INSTALL_PREFIX to RPM_INSTALL_PREFIX if not already set for post and postun sections

*** empty log message ***

Misc fixes.

* Gracefully exit with an error messase if rpmbuild is not found.
* Make dependencies of executable files (both libraries and proper executables)
  relocatable. This only applies for our stuff, not for that we get from the
  system.

add support for the "## SUBPACKAGE <subpackage>" directive, in order to create subpackages

add support for options to the common spec file sections (%prep, %build, etc.)

make rpmLocation a member of Package, and uniform error messages for post-build checks

default for trace is set to False

actual base release version is now passed via cmstc url now along with the tag collector base queue. No need to have special check for _ONLINE. Old cmstc url will still work

Options to configure server-side tools during upload.

* Adds --server-apt-root option to specify which environment to be
  sourced on upload.
* Adds --server-genbasedir-path to specify which genbasedir to pick up
  on upload (this is needed because we are actually using a
  hand patched version of genbasedir, even compared to what we have built).

Pick up --server option correctly.

Now it does not remove . from the gccver when system compiler is used. Using this will rebuild every thing which uses system compiler to build so basically online and osx builds

marged back the 1.313 revision including the svn fixes

Fixes missing "Done processing" message as reported by Andreas.

RPM scriptlet (%post, %pre, etc) parsing now done in a separate helper method.

Remove old & unused apt stuff

Silenced output from skipPreInstall option: the output now will only appear in the DEBUG mode.

Merge in changes for online release from rev. 1.294-296 on top of V00-08-07 (this tag is currently used for build CMSSW 2.2.X releases). Also silenced output from skipPreInstall option: the output will only  appear in the DEBUG mode.

Creates a git repository after unpacking sources.

In order to facilitate porting to new platforms, now cmsBuild creates
a temporary git repository with the unpacked sources and deletes it
if a build succeeds. This way, in the case the build fails one can patch
sources inplace and get the delta by simply doing

    git diff

in the `BUILD/arch/group/name/version/` directory.
Of course, in the case git is not there nothing happens.
This will trigger a rebuild of all the sources.

Misc fixes to PackageManagement.pl.

* Fixes the --mypackagefile option so that it works with absolute paths.
* Does not use xargs -r option since it does not work on macosx.
* Introduction of PackageManagement.pl broke the --work-dir option. This
  fixes the problem.

Fixes (some) of the print-outs on exception.

Due to a stupid bug, exception messages are splitted by letters. This solves
some of the issues.

Fixes the deprecate-local command and related to behave more reliably.

* When a conflict is found, the full "deprecate-local" to be used to
  resolve it is printed out.
* `deprecate-local` now actually works in different conditions, especially when
  the workdir was not the default one.

08 compatible cmsBuild for patch builds

Added an option --skip-pre-install-checks to skip execution of default CMS
pre-install scriplet. This is needed for example for building online rpms
installable by a superuser (quattor requirement).

adding fixes from Lassi

hard-coded path to lndir to avoid trouble ith upload

Quitting tracker message moved to the `TRACE` log level.

Hardcodes /usr/X11/bin/lndir.

revert back to head

patch build support for sources

revert to previous head

Multiple revisions on server bug fixed.
* Reported by David.

geTest -> cms repo

Fixes a bug related to the new revision support.
* Reported by Zhen and Frank.

Allows packages not to "Requires: gcc" if `## NOCOMPILER` specified.
* This is useful for "script" only packages like cms-common and should allow
  data files to be compiled in parallel with gcc. Hurray!

fix csh bug in line that sources dependencies

Patched version used for super-user installable online releases

Fixes bug in help method.

sorting checksums

Replaces `source` with `.`.
* Required by Ubuntu ash shell.

Misc fixes.
* --ignoreCompileErrors renamed --ignore-compile-error.
* Loggin levels are now NORMAL=10, DEBUG=20, TRACE=30.

More clean ups.
* PackageFactory is now passed only once per Command. This means that a bunch
  of stuff done in initialization is now done only once.
* createWithSpec helper function is replaced by PackageFactory.createWithSpec
* The class for the cmsos.file dumper is now a parameter of the PackageFactory
  constructor. This makes the PackageFactory still indipendent of CMSDIST files,
  so that the test_Package01.py works again.
* test_Package01.py is now working again. An assert was broken because
  Package.sources now stores absolute paths, rather than relative ones.

Lots of refactoring.
* PackageFactory is now the owner of the regular expression used to parse the
  headers in the spec file. The regular expressions themselves are stored as
  member variables of the HeaderMatchingRegexps class.
* calculateChecksum helper method is gone. A new class ChecksumCalculator is
  provided to calculate the checksum of a given package. All the code to
  calculate the checksum which was previously sparse between calculateChecksum
  and Package.calculateChecksums is now collected there.
* fetchLocal is not used anymore to get cmsos.file. A special object of type
  CmsosDumper is now available in every Package (owned by the PackageFactory)
  which caches cmsos.file and dumps it in the wanted location.
  There is now a method Package.dumpCmsos which writes cmsos to the dir with
  all the sources for a given package.
* Package.calculateChecksums was renamed to Package.calculateChecksum. It now
  uses the ChecksumCalculator object and as a result the Package.checksums
  property is now gone.
* Package.sources list now contains the full, absolute, path for sources which
  are local. This way we avoid in a number of places (doDownload, download) to
  have to pass the cmsdist location and do the "join" every time.
  Some code which was relying on the source not having a "/" in it to decide
  wether or not its a local source file, now uses a regular expression.
* There is now an ActionFactory to create various build actions.
  This simplifies the creation of actions. Moreover, when creating the action
  tree actions which do nothing (e.g. download and empty set of sources) are
  not added to the tree.

More fixes.

Final attempt to fix the asmcklmckasdcc 'screen' problem...

More fixes to handle escape characters in user environment.

Variable PACKAGE_NAME_CATEGORY added to init.sh/init.csh

Code cleanup.
* A Package object now uses the factory used to create it to create the Packages
  associated to its dependencies.

More cleanups:
* Package.sectionPreambles and Package.sectionPostambles are now properties.
  Their actual value is now set by PackageFactory.
* Package.sectionPreambles is now read-only.

More cleanups of the code in sight of handing it over to Andreas and David.
* unsafe_mode cfg option renamed unsafeMode for consistency.
* rpmGetPreamble helper method removed.
* PackageFactory is now responsible for loading the preamble and injecting
  it in newly created Packages.
* Package.initWithSpec now takes a list of lines as input. File reading is
  done in PackageFactory.createWithSpec. This simplifies the writing of
  unittest for the Package class since it now does not depend on the
  existance of CMSDIST.
* Package.preamble is now a property.
* Package.calculateChecksums now does not reload the spec to calculate its
  checksum but uses the copy already in self.origSpec.
* Package.rpmEvalString restructured for easier reading.
* Package.rpmEvalString now throws an exception if the rpm-preamble.file is
  malformed.

Expand spec refactoring.

rpmRequiresAndSources helper function moved to Package.getRequiresAndSources.
* Package.__getTmpSpecName introduced.

Now also the requires_cache takes into account the architecture.

Unused `pickle` import removed.

Refactoring of calculateChecksums
* using a join over a list of strings rather than a for loop.

Correctly detect --use-system-compiler default for given architecture.
* Making sure that the correct default for --use-system-compiler is adopted
  when an explicit architecture is specified via --architecture option.

Beautification of the printing of lists.

Bootstrap done message also in non-interactive mode.

Taking the abspath of workDir at the beginning of the bootstrap procedure.

guessArchitecture now takes the --use-32-bit-on-64 into account.
* `--32-bit-on-64` bit renamed `--use-32-bit-on-64`.
* `useLinux32` renamed `use32bitOn64`.

More clean ups:
* More messages moved to DEBUG level.
* Fixes syntax error in debug message.

cmsBuild is now able to detect the architecture to be used.
* Also detects wether or not to use the system compiler by default. It's now
possible to have uniform configuration files between osx and linux.
* It is still possible to override the detection via the usual command-line /
configuration options.
* guessArchitecture / guessUseSystemCompiler helper methods added.

More cleanups of the fetching subsystem:
* There is now an helper method initDownloadHandlers that takes care of setting
  up the detected download handlers.
* Revamped test script for download handlers
* Now the download handlers take a specific DownloadOptions object rather
  than the global options one.
* Typo fixed: selectHttpDownloadHanler is now selectHttpDownloadHandler.
* downloadTc now calls packCheckout using tempdir rather than exportpath.

Fixes download of sources from CVS.

Misc fixes of bug reported by David:
* Avoids messing with the SHELL environment (fixes problem in building gcc
  using tcsh?).
* Uses uploadTmpRepository rather than obsolete tmpRepositoryName.

fix tag collector fetch code in cmsBuild

Uses absolute path for target library when fixing it via install_name_tool.
* MacOSX only.

More flexibility in naming convention for temporary repository.
* Option --upload-tmp-repository <name> added which allows repository called
  something.<name> rather than just something.username.

Method `downloadSvn` is now the handler for `svn` scheme.

Removing FIXME regarding fixed bug

Check added for which download handler (wget or curl) to use for http(s)/ftp(s).

More fixes to have %cmsos expanded in Sources.
* fetchLocal creates the target directory if it is not there.
* typo removed in the error handling of bad/missing configuration filename.

--only-once option added.
* Passed on to bootstrap.sh

cmsBuild now prepends linux32 if the architecture requires it.
* No more need of extra linux32 in front of ./cmsBuild.

Configuration files now has a "home" macro.

More fixes to the cfg parser for cmsBuild.
* TagCacheAptImpl has a new method `update` which does the apt-get update.
* --cmsdist-tag default is now "" rather than None.
* --compiling-processes default is now 0 rather than None
* saveOriginalEnvironment and restoreOriginalEnvironment helper functions added
  to save / restore shell environment between one command and the other (to
  allow different environment per command).
* Logic for option parsing now behaves correctly. Options precedence is:
    * Local section in the configuration file.
    * Options in `globals` section.
    * Command line options.
* Command.run now takes care of bootstrapping (if requested) and handles
  environment setup.
* Cfg file parser is now case sensitive.

%(architecture)s macro available in configuration file

Configuration file to create a bootstrap kit made working.
* configs/test_create-bootstrap.cfg created
* Command.__lt__ moved to Command.__cmp__ for proper sorting of the commands.
* It is now possible to specify `%(tmpdir)s` and `%(date)s` in the configure file
  as placeholders for a randomly created temporary directory (via `mkdtemp`)
  and for the date of the day.
  Format for the temporary directory and for the date can be specified (only)
  from command line options `--temp-dir-prefix` and `--date-format`.
* --assume-yes (assumeYes in cfg) option is now passed to bootstrap script.
* Missing parameter added to a `downloadWget ()` call.

Command execution re-engineered.
* class Command now has a `run` method. It takes care of switching to the
  approriate directory, fetching CMSDIST (if required) and calling the
  callback.
* `Command`s are now executed via their "run method".

parseCfgFile now uses setOptions as well

cmsBUild bootstrap now takes -architecture <architecture> as an option, not as an argument.

cmsBuild can now execute multiple commands in a row.
* Useful, for example to bootstrap, build, check and upload in a single
  shot.
* Command class introduced.

cmsBuild is now able to access CMSDIST on remote servers (CVS, git, TagCollector).

* If the option value for --cmsdist starts with cvs://, git://, tc://,
  http://, etc, cmsBuild interprets it as an url and fetches the files into
  $PWD/CMSDIST (possibly overriding what's already there). Notice that this
  was only tested for CVS albeit the logic does not depend on it.

* It is now possible to omit the cvs server and password in cvs:// urls. This
  is in particular nice to specify CMSDIST checks out from cvs with

        --cmsdist "cvs://?tag=ge20071204"

* MalformedUrl exception now take an optional missingParams parameter to be
  used to specify which bits of the url where missing.

Better error message when not able to install a package.

Using the new single bootstrap.sh

proper dependencies for rpm. online_release stuff removed until we can actually provide proper support for different requires per different platforms

cmsBuild sets now cmscompiler and compilerRealVersion. Required by generic compiler support.

Patch from lassi to have %pre section exiting with 1 when installing as root

SourcesDownload and InstallFromServer action fixed.
    * a missing "self." added
    * Missing .split("\n") added.

bugfix in fetch command

stripping spaces at the beginning and end of # INITENV commands

tmp always created if it does not exists

upload command re-engineered
	* --sync-back option added
	* Now all the actions on the repositories are done by the Repository class
	  this results in an easier to read upload method.
	* Full chain tested on a separate copy of the cms repository. The new
	  workflow seems to be 100% compatible with what we were doing before.

Uber-patch for cmsBuild:
	* Tag assignment mechanism now fully based on apt-get, no more need for a
	  tag database or a central cgi-script to keep track of the association
	  between a build checksum and the associated tag. Notice that no migration
	  is required for the old packages, and while new and old packages will
	  not be mixed they also don't interfere with each other.
	* 'check' command added to make sure that the BUILD area is consistent
	   with the build procedure performed (e.g. no tampering with the BUILD
	   area happened) and with the server (e.g. no one uploaded a package with
	   the same name in the official repository).
	* 'check' command is based on a new action-based workflow builder which
	   decomposes a task in smaller actions, builds the decision tree of which
	   action will have to be taken and which not and checks that the actual
	   result is consistent. In a later version we could use this mechanism to
	   achieve even higher level of parallelism (e.g. download sources of other
	   packages while gcc builds).
	* 'upload' command added to replace the separate updateServer.sh script
	   used during install.sh era.
	   The command performs a 'check' (see above) before the upload, to ensure
	   that junk is not uploaded.
	* 'upload' command has initial support for 'upload permissions' to avoid
	   having random developers uploading random packages with random tags.
	* dozens of checks, speed-ups and bugfixes.

Merge branch 'merge-workers' of ssh://ktf@hifi-bonsai.com/Users/git/PKGTOOLS into merge-workers

Remove the limit on the packages in the schedule queue that can be scheduled
at once.

Better scheduling algorithm for workers.

	* Now we dispatch a package as soon as its dependencies are done.

Better print-out for thread info.

Merge branch 'git-download'

Corrected command for tagcollector download.

	* $tempdir replaced with %(tempdir)s

Better success message on bootstrap.y

Now also non bootstrapped installation have some memory of which packages where already built.

Better printout when building a package. Including the dependencies.

Message displayed when using a non bootstrapped area is now more
explicit.
