Whenever an environment session was provided by an asynchronous service,
e.g., the depot_rom of the sculpt scenario, the session quota was not
transferred to the server at session-creation time. This resulted in a
slow depletion of the server's quota over time. This patch ensures that
the delivery of session quota is consistent with the information
reported to the server as session argument.
The 'Child::_revert_quota_and_destroy' assumes to be called from the
client's context, which is normally the case when destroying sessions.
However, if a client's session outlives the client (because the
asynchronous close request to the server is still pending), the session
cleanup is performed in the context of the server. Here, the
'session_response' implementation wrongly called
'_revert_quota_and_destroy' to the effect that the session quota was
withdrawn from the server (good) but subsequently transferred back to
the server (bad). The patch replaces the call of
'_revert_quota_and_destroy' with only the first - correct - part of the
transaction.
This test monitors the RAM quota of a dynamic init and a server hosted
within the dynamic init in the presence of a repeatedly created and
destructed client.
Newer revisions of parted require special privileges due to use of the
dmidecode tool, which logs permission errors to standard error. In these
cases parted still succeeds with its operation, so just ignore the
jabbering and prevent expect to exit.
Previously we were doing the initialization once over all domains,
remembered which of them became invalid and destroyed those afterwards.
This isn't sufficient. As soon as one domain becomes invalid we have to
dissolve/destroy this one, deinitialize all other domains again (as they
could contain references to the invalid domain) and retry to initialize
them from the beginning. We proceed with this until we have one run
without a domain becoming invalid. Then we can be sure that the last
initialization run did not create references to any invalid domain.
Issue #2840
The generic helper Avl_string_tree of the NIC router is currently only
used for finding domains via their names, but in the future it can be
used for finding uplinks by their labels also. Additionally, it enables
us to throw an exception when inserting two elements with the same
identifier.
Issue #2840
This patch suppresses the start of components that cannot run because
obvious runtime dependencies (used servers) are missing in the runtime.
In this situation, the sculpt manager gives diagnostic feedback to the
user in the runtime dialog.
* Get rid of the base classes Rule and Leaf_rule,
* Make log output about initiated or invalid routing rules conform to the rest
of the router log, and
* Ensure that each type of routing rule when being invalid invalidates its
whole domain.
Issue #2840
On Linux, we have a tap device as NIC back end but there is no one to
ping to in the subnet of the tap device. On FOC, the tests seem to trigger
a bug in the destruction of components with parent.exit(X); .

Sculpt's discovery of the default storage target can be intercepted by
user input (i.e., pointer movements) at boot time. The patch makes this
intervention mechanism robust for the case where nitpicker's first hover
report arrives after all storage devices were already scanned.
By tracking the states for an interactive selected NIC target (managed)
and a manual-defined NIC target (config/nic_router) separately, the
sculpt manager becames able to present the user with the ability to
interactively disable and re-enable a manually-managed network
configuration.
The sculpt manager wrongly paid for the nitpicker session of the fader
out of its own pocket. This patch reduces the quota transfer to the
amount provided the fader.
When updating the GPT to match the underlying block device, the
protective MBR will normally also be updated. In case a hybrid MBR is
used, as is done if 'image/disk' is specified, setting the
'preserve_hybrid' flag will prevent the component from overriding the
MBR.
The condition was too rigid. In the case where no motion occurred in
between the press and release events of the magic button, the delayed
press event would not be delivered. This - in turn - confused other
components (like nitpicker) down the input chain.
for such classes where it should be safe and where we have seen issues.
Disabling in general bus master DMA causes on some machines hard hangs, e.g.
because the USB handover protocol was violated.
Fixes#2835
In contrast to most information of init's state reports, which can be
monitored at a relatively low rate (like 2 seconds in Sculpt's runtime),
resource requests call for an immediate response by the consumer of the
report. Otherwise the requesting child stays unnecessarily blocked until
the next rate-limited state report is due. This patch adds a fast lane
for such low-latency state updates to init.
- support saving of files with no file name extension
- make the the "All Files (*)" file selection filter the default to see
configuration files immediately
Fixes#2844
This commit updates Early-Adopters (EA) version of Sculpt to the version
for The Curious (TC). Most importantly, it contains the new interactive
sculpt-manager component that automates many system management and
configuration tasks.
