Every service method built and disposed its own PveHttpClient, and each
client owned a fresh HttpClientHandler, so every API call was a TCP connect
plus a TLS handshake and WaitForTask paid that 300 times over a ten-minute
wait.
PveServiceBase now owns the injected-or-fresh client lifetime behind one
Invoke helper; the 201 hand-written try/finally blocks across the 16
services collapse to calls on it, and the nested NodeService/VmService
instances receive the injected client. PveHttpClient takes its handler
from a process-wide PveHandlerCache keyed on (host, port,
skipCertificateCheck) and never disposes it, so the connection pool
outlives any one client. WaitForTask holds one client for the whole wait
and, when no pollInterval is supplied, backs off from 1 s toward a 10 s
cap, never sleeping past the deadline.

PveHttpClientLockRetryTests set GuestLockRetry's retry budget via reflection
on a private field with no production writer, and scripted two lock
failures to land inside a 400ms window. A cold or loaded CI runner's
first-attempt JIT and scheduling could burn past 400ms before the second
attempt started, failing the test though the retry itself was correct
(#134).
GuestLockRetry.ExecuteAsync gains an internal overload that takes the
inter-attempt delay as a Func<TimeSpan, Task>; the public overload keeps
defaulting to Task.Delay, so production behaviour (45s window, budget/4
capped at 2s) is unchanged. PveHttpClient gains a matching internal
constructor seam (window, handler, delay), replacing the reflection the
tests used for both the private HttpClient and the retry window. Tests
now pass a no-op delay, so the retry loop's real elapsed time drops to
microseconds and the production 45s window can never be exhausted by
runner speed.
Two tests pin that production still waits for real: one records the
delay invocations through the internal seam and asserts the computed
interval, the other drives the public overload with a small window and
asserts wall-clock time actually advances. Both were mutation-tested
against a no-op-default regression and fail without the fix.
The give-up test was renamed (PutAsync_DoesNotReissueWhenTheRetryWindowIsAlreadySpent)
to describe what TimeSpan.Zero actually proves: the client never attempts
a reissue once the budget reads spent, not a multi-attempt exhaustion
sequence — a review finding on the original name.
Out of scope, noted for follow-up: GuestLockRetryTests.cs's synchronous
Execute() tests still use a 400ms ShortWindow with real Thread.Sleep,
which is the same flake shape on the sync path; Execute() has no delay
seam. PveHttpClientTimeoutTests.cs and PveHttpClientFormEncodingTests.cs
still reflect on the private _httpClient field, which the new handler
seam could also retire.

* fix: escape dynamic path segments in three Remove-* cmdlets
Wrap Storage, Vnet, and Zone parameters with Uri.EscapeDataString() in
RemovePveStorageCmdlet, RemovePveSdnVnetCmdlet, and RemovePveSdnZoneCmdlet
to prevent path traversal attacks via the API path.
Add xUnit test demonstrating that escaped paths preserve percent-encoding
(preventing path collapse) while unescaped paths allow segment traversal.
Fixes#145
* fix: route Remove-Pve{Storage,SdnVnet,SdnZone} through their services
Delete the private PveHttpClient construction and inline
Uri.EscapeDataString call in RemovePveStorageCmdlet,
RemovePveSdnVnetCmdlet and RemovePveSdnZoneCmdlet; call
StorageService.RemoveStorage / NetworkService.RemoveSdnZone /
NetworkService.RemoveSdnVnet instead, which already escape the
identifier identically and are now the single place doing so.
Add ValidatePattern on the Storage/Vnet/Zone parameters as defense
in depth, anchored with \A/\z so a trailing newline cannot slip a
disallowed character past the gate.
Replace PveHttpClientPathEscapingTests with a version that actually
regression-tests the real Uri parser (asserts both that %2F survives
and that the unescaped form is absent), and add
StorageServiceTests/NetworkServiceTests cases that mock
IPveHttpClient and verify the exact escaped DELETE path for a
traversal-attempt name.

Two non-blocking review observations.
A 45s retry is indistinguishable from a hang with nothing on the wire, so
GuestLockRetry.Execute takes an onRetry hook and InvokeGuestTask reports
each reissue through WriteVerbose.
The gap between attempts now scales with the budget, capped at the 2s
production value. A caller passing a short window wants a fast answer
rather than one long sleep, which also takes the retrying unit tests off
a real 2s sleep each: the xUnit run drops from 8s to 4s. PveHttpClient's
window becomes a field so those tests can shorten it too.
WaitForStatusTransition refused to return while snapshot.Locked, and its
comment quoted the exact error it was meant to prevent. Locked reads the
guest config's lock: property; the failure is the flock on
/var/lock/qemu-server/lock-<vmid>.conf, which PVE exposes nowhere.
The flock cannot be observed, so it is retried. GuestLockRetry reissues an
operation for a bounded 45s while PVE reports failing to enter lock_config
for a guest, which it raises before doing any work.
Two seams, because the failure has two surfaces. PveHttpClient.SendAsync
retries the request for operations PVE serialises in the API handler; it
takes a request factory because an HttpRequestMessage cannot be resent.
PveCmdletBase.InvokeGuestTask reissues the call and re-waits its task for
operations serialised in the forked worker, where the POST returns 200 and
only the task fails. WaitForStatusTransition routes through the latter,
hence Func<PveTask>.
The predicate is path-specific and anchored at the start of what PVE said:
lock_file uses identical wording for storage, LVM and HA locks, and a
qmclone that fails after allocating disks must not be reissued into
"VM already exists". That requires the raw text, so it reads
PveTaskFailedException.ExitStatus and PveApiException.ApiMessage.
The Locked check stays — it is correct for the config lock — with a comment
that says so.
Closes#113
ExecuteGuestCommand JSON-serialized the args array into the agent/exec
'input-data' field — which is the process's STDIN, not its arguments. So
guest commands ran with no argv: cmd.exe started interactively and the
JSON blob ['/c','echo',...] arrived at its prompt.
PVE's agent/exec 'command' parameter is itself an array (element 0 = the
executable, the rest = argv) sent as repeated form keys. The low-level
client couldn't express repeated keys (Dictionary<string,string> only),
so:
- Add PostAsync(string, IEnumerable<KeyValuePair<string,string>>) to
IPveHttpClient/PveHttpClient; BuildFormContent now emits one key=value
field per pair, so a key may repeat.
- ExecuteGuestCommand builds command = [exe] + args as repeated 'command'
fields and no longer touches input-data.
Tests: form-encoder repeated-key + per-value encoding cases; VmService
tests asserting the command array, order, and absence of input-data; an
integration regression guard that echoes an arg and checks it round-trips
as stdout.
Tracked as F091. Closes#68.

PveHttpClient.EncodeFormValue encoded &, =, +, space, and % but left ';'
literal. PVE's application/x-www-form-urlencoded parser treats a raw ';'
as a field separator (the historical alternative to '&'), so a value like
boot=order=scsi0;ide2
was split into 'boot=order=scsi0' plus an empty 'ide2' field, and PVE
rejected the PUT with "ide2: unable to parse drive options". This broke
any multi-device boot order set via Set-PveVmConfig -AdditionalConfig,
and any other value containing ';'.
Encode ';' as %3B. Safe under the existing minimal-encoding policy that
keeps ':' and '!' literal for cluster-join: cluster-join payloads never
contain ';', and PVE url-decodes config form values.
Tracked as F088. Closes#64.

When HttpClient.Timeout elapses, .NET throws TaskCanceledException — not
HttpRequestException — so the existing catch in PveHttpClient.SendAsync
missed it and callers got a raw stack trace. With -TimeoutSeconds now
configurable and documented, this gap became user-visible.
In .NET 5+ HttpClient surfaces transport timeouts as TaskCanceledException
with a TimeoutException inner; user-driven token cancellation does not.
Catch by that inner-type signature and rethrow as PveApiException with
HttpStatusCode.RequestTimeout, the resource path, and a message that
reports the configured timeout.
Adds SendAsync_TimeoutFires_ThrowsPveApiExceptionWithRequestTimeout which
swaps in a delaying HttpMessageHandler with a 50ms timeout to exercise
the path deterministically. Drops the redundant
DefaultSessionTimeoutIs100Seconds test (covered by
PveSessionTests.Timeout_DefaultIs100Seconds and the existing flow-through
test).
Addresses PR #61 review feedback.

PveHttpClient was constructed without setting HttpClient.Timeout, so
.NET's 100s default applied to every request. Multi-GB ISO uploads via
Send-PveFile on a real LAN reliably tripped this with TaskCanceledException
after 100 seconds, and there was no way to override it.
- PveSession gains a Timeout (TimeSpan) property, defaulting to 100s.
- PveHttpClient accepts an optional per-instance timeout override that
takes precedence over the session timeout.
- Connect-PveServer exposes -TimeoutSeconds to set the session default.
- Send-PveFile and Invoke-PveStorageDownload expose -TimeoutSeconds with
a 30-minute implicit default so large uploads/downloads do not trip
the 100s default. -TimeoutSeconds 0 means Timeout.InfiniteTimeSpan.
Tracked as F087. Closes#59.
