      Big set of changes for deferred/scheduled/offline aggregates: · 6f17de73
      Leigh Stoller authored
      * I started out to add just deferred aggregates; those that are offline
        when starting an experiment (and marked in the apt_aggregates table as
        being deferable). When an aggregate is offline, we add an entry to the
        new apt_deferred_aggregates table, and periodically retry to start the
        missing slivers. In order to accomplish this, I split create_instance
        into two scripts, first part to create the instance in the DB, and the
        second (create_slivers) to create slivers for the instance. The daemon
        calls create_slivers for any instances in the deferred table, until
        all deferred aggregates are resolved.
      
        On the UI side, there are various changes to deal with allowing
        experiments to be partially create. For example used to wait till we
        have all the manifests until showing the topology. Now we show the
        topo on the first manifest, and then add them as they come in. Various
        parts of the UI had to change to deal with missing aggregates, I am
        sure I did not get them all.
      
      * And then once I had that, I realized that "scheduled" experiments was
        an "easy" addition, its just a degenerate case of deferred. For this I
        added some new slots to the tables to hold the scheduled start time,
        and added a started stamp so we can distinguish between the time it
        was created and the time it was actually started. Lots of data.
      
        On the UI side, there is a new fourth step on the instantiate page to
        give the user a choice of immediate or scheduled start. I moved the
        experiment duration to this step. I was originally going to add a
        calendar choice for termination, but I did not want to change the
        existing 16 hour max duration policy, yet.

      Image handling changes: · fe8cc493
      Leigh Stoller authored
      1. The primary change is to the Create Image modal; we now allow users
         to optionally specify a description for the image. This needed to be
         plumbed through all the way to the GeniCM CreateImage() API. Since
         the modal is getting kinda overloaded, I rearranged things a bit and
         changed the argument checking and error handling. I think this is the
         limit of what we want to do on this modal, need a better UI in the
         future.
      
      2. Of course, if we let users set descriptions, lets show them on the
         image listing page. While I was there, I made the list look more like
         the classic image list; show the image name and project, and put the
         URN in a tooltip, since in general the URN is noisy to look at.
      
      3. And while I was messing with the image listing, I noticed that we
         were not deleting profiles like we said we would. The problem is that
         when we form the image list, we know the profile versions that can be
         deleted, but when the user actually clicks to delete, I was trying to
         regen that decision, but without asking the cluster for the info
         again. So instead, just pass through the version list from the web
         UI.

      A lot of work on the RPC code, among other things. · 56f6d601
      Leigh Stoller authored
      I spent a fair amount of improving error handling along the RPC path,
      as well making the code more consistent across the various files. Also
      be more consistent in how the web interface invokes the backend and gets
      errors back, specifically for errors that are generated when taking to a
      remote cluster.
      
      Add checks before every RPC to make sure the cluster is not disabled in
      the database. Also check that we can actually reach the cluster, and
      that the cluster is not offline (NoLogins()) before we try to do
      anything. I might have to relax this a bit, but in general it takes a
      couple of seconds to check, which is a small fraction of what most RPCs
      take. Return precise errors for clusters that are not available, to the
      web interface and show them to user.
      
      Use webtasks more consistently between the web interface and backend
      scripts. Watch specifically for scripts that exit abnormally (exit
      before setting the exitcode in the webtask) which always means an
      internal failure, do not show those to users.
      
      Show just those RPC errors that would make sense users, stop spewing
      script output to the user, send it just to tbops via the email that is
      already generated when a backend script fails fatally.
      
      But do not spew email for clusters that are not reachable or are
      offline. Ditto for several other cases that were generating mail to
      tbops instead of just showing the user a meaningful error message.
      
      Stop using ParRun for single site experiments; 99% of experiments.
      
      For create_instance, a new "async" mode that tells CreateSliver() to
      return before the first mapper run, which is typically very quickly.
      Then watch for errors or for the manifest with Resolve or for the slice
      to disappear. I expect this to be bounded and so we do not need to worry
      so much about timing this wait out (which is a problem on very big
      topologies). When we see the manifest, the RedeemTicket() part of the
      CreateSliver is done and now we are into the StartSliver() phase.
      
      For the StartSliver phase, watch for errors and show them to users,
      previously we mostly lost those errors and just sent the experiment into
      the failed state. I am still working on this.

      Add extension limiting to manage_extensions and request extension paths. · f71d7d95
      Leigh Stoller authored
      The limit is the number of hours since the experiment is created, so a
      limit of 10 days really just means that experiments can not live past 10
      days. I think this makes more sense then anything else. There is an
      associated flag with extension limiting that controls whether the user
      can even request another extension after the limit. The normal case is
      that the user cannot request any more extensions, but when set, the user
      is granted no free time and goes through need admin approval path.
      
      Some changes to the email, so that both the user and admin email days
      how many days/hours were both requested and granted.
      
      Also UI change; explicitly tell the user when extensions are disabled,
      and also when no time is granted (so that the users is more clearly
      aware).

      Changes related to extensions: · e1b6076f
      Leigh Stoller authored
      * Change the units of extension from days to hours along the extension
        path. The user does not see this directly, but it allows us to extend
        experiments to the hour before they are needed by a different
        reservation, both on the user extend modal and the admin extend modal.
      
        On the admin extend page, the input box still defaults to days, but
        you can also use xDyH to specify days and hours. Or just yH for just
        hours.
      
        But to make things easier, there is also a new "max" checkbox to
        extend an experiment out to the maximum allowed by the reservation
        system.
      
      * Changes to "lockout" (disabling extensions). Add a reason field to the
        database, clicking the lockout checkbox will prompt for an optional
        reason.
      
        The user no longer sees the extension modal when extensions are
        disabled, we show an alert instead telling them extensions are
        disabled, and the reason.
      
        On the admin extend page there is a new checkbox to disable extensions
        when denying an extension or scheduling termination.
      
        Log extension disable/enable to the audit log.
      
      * Clear out a bunch of old extension code that is no longer used (since
        the extension code was moved from php to perl).

      Fixes/Changes for reservations: · 79d99fa8
      Leigh Stoller authored
      1. Fix the user extend modal to show the proper number of days they can
         extend.
      
      2. Fix the admin extend modal warning when the extension would violate
         max extension, it was not showing. Add new alerts when we cannot get
         max extension from the cluster or no extension at all allowed.
      
      3. Reduce number of days in the box to max allowed. Warn loudly if you
         type a different number and its greater then max extension.
      
      4. Add "force" box to override. Use with caution. Added the plumbing
         through to the back end as new force option to RenewSliver().
      
      5. Add check in RenewSliver() to ask the reservation system if extension
         allowed before doing it. This was missing, should solve some of the
         over book problems.

      Changes for automatic lockdown of experiments: · 8f4e3191
      Leigh Stoller authored
      1. First off, we no longer do automatic lockdown of experiments when
         granting an extension longer then 10 days.
      
      2. Instead, we will lockdown experiments on case by case basis.
      
      3. Changes to the lockdown path that ask the reservation system at the
         target cluster if locking down would throw the reservation system
         into chaos. If so, return a refused error and give admin the choice
         to override. When we do override, send email to local tbops informing
         that the reservation system is in chaos state.

      Deal with user privs (issue #309): · d1516912
      Leigh Stoller authored
      * Make user privs work across remote clusters (including stitching). I
        took a severe shortcut on this; I do not expect the Cloudlab portal
        will ever talk to anything but an Emulab based aggregate, so I just
        added the priv indicator to the user keys array we send over. If I am
        ever proved wrong on this, I will come out of retirement and fix
        it (for a nominal fee of course).
      
      * Do not show the root password for the console to users with user
        privs.
      
      * Make sure users with user privs cannot start experiments.
      
      * Do show the user trust values on the user dashboard membership tab.
      
      * Update tmcd to use the new privs slot in the nonlocal_user_accounts
        table.
      
      This closes issue #309.

      Rework how we store the sliver/slice status from the clusters: · e5d36e0d
      Leigh Stoller authored
      In the beginning, the number and size of experiments was small, and so
      storing the entire slice/sliver status blob as json in the web task was
      fine, even though we had to lock tables to prevent races between the
      event updates and the local polling.
      
      But lately the size of those json blobs is getting huge and the lock is
      bogging things down, including not being able to keep up with the number
      of events coming from all the clusters, we get really far behind.
      
      So I have moved the status blobs out of the per-instance web task and
      into new tables, once per slice and one per node (sliver). This keeps
      the blobs very small and thus the lock time very small. So now we can
      keep up with the event stream.
      
      If we grow big enough that this problem comes big enough, we can switch
      to innodb for the per-sliver table and do row locking instead of table
      locking, but I do not think that will happen

      Separate user vs admin lockdown, previously they were intertwined. · 8e88917e
      Leigh Stoller authored
      User lockdown is as before, user can override that on the terminate
      page. Admin lockdown is like Classic lockdown; the flag must be cleared
      before the experiment can be terminated, there is no override on the
      termination page.
      
      UI changes on the status and admin extend page for the additional
      flag (instead of a single lockdown, there are now two).
