In `@compute/src/main/java/org/zstack/compute/vm/UpdateVmInstanceMetadataGC.java`:
- Around line 35-40: There is a TOCTOU race between checking
chainInfo.getPendingTask().isEmpty() (from thdf.getChainTaskInfo(...)) and
actually submitting the GC task (e.g. chainSubmit), so add a second verification
just before submission: re-fetch ChainInfo via
thdf.getChainTaskInfo(getUpdateVmInstanceMetadataSyncSignature(vmInstanceUuid))
and only proceed with the submission if getPendingTask().isEmpty() still holds
otherwise call completion.cancel(); alternatively document that duplicate
submissions are acceptable for GC; update the code paths around
getUpdateVmInstanceMetadataSyncSignature, thdf.getChainTaskInfo,
completion.cancel and the chain submission site to perform this double-check or
explicit synchronization.
In `@compute/src/main/java/org/zstack/compute/vm/VmInstanceApiInterceptor.java`:
- Line 24: Remove the unused import of APIRegisterVmInstanceMsg from
VmInstanceApiInterceptor: open the VmInstanceApiInterceptor class, locate the
import statement "import
org.zstack.header.storage.primary.APIRegisterVmInstanceMsg" and delete it (the
intercept() method in VmInstanceApiInterceptor does not handle this message and
APIRegisterVmInstanceMsg is handled by PrimaryStorageBase), leaving only the
imports actually used by the class.
In `@compute/src/main/java/org/zstack/compute/vm/VmInstanceBase.java`:
- Around line 9399-9411: In the bus.send callback (run method) that builds an
UpdateVmInstanceMetadataOnPrimaryStorageReply, ensure the failure branch calls
bus.reply(msg, reply) before invoking submitUpdateVmInstanceMetadataGC();
specifically, in the run override inside VmInstanceBase where you create the
reply on !r.isSuccess(), set the error on reply and immediately call
bus.reply(msg, reply) (using the same msg and reply variables) and only then
call submitUpdateVmInstanceMetadataGC() so the caller is replied to and won't
hang.
- Around line 9389-9392: The code assumes Tuple tuple =
Q.New(VolumeVO.class)...findTuple() always returns non-null; if tuple is null
the subsequent tuple.get(...) causes NPE. Fix: after obtaining tuple in
VmInstanceBase (the block that queries VolumeVO/VolumeVO_/VolumeType.Root with
msg.getUuid()), check if tuple == null and if so construct and send an error
reply and return (do not proceed to read primaryStorageUuid/rootVolumeUuid);
ensure the error contains context (vm uuid) and use the normal reply/error path
used elsewhere in this class.
In `@core/src/main/java/org/zstack/core/gc/GarbageCollectorManagerImpl.java`:
- Around line 287-291: 在 handle(SubmitTimeBasedGarbageCollectorMsg) 中对
msg.getGcInterval()（Long）和 msg.getUnit() 做非空与范围校验，避免自动拆箱 NPE 和无效调度：如果 gcInterval
为 null 或 gcInterval <= 0 或 unit 为 null，则不要调用 msg.getGc().submit(...); 构造并通过
bus.reply(msg, reply) 返回一个错误 MessageReply（含描述性错误信息），否则正常调用
msg.getGc().submit(msg.getGcInterval(), msg.getUnit()) 并返回成功回复；参照方法和字段名：handle,
SubmitTimeBasedGarbageCollectorMsg, getGc(), getGcInterval(), getUnit(), submit。
In
`@core/src/main/java/org/zstack/core/gc/SubmitTimeBasedGarbageCollectorMsg.java`:
- Around line 7-10: SubmitTimeBasedGarbageCollectorMsg currently includes a
TimeBasedGarbageCollector instance which breaks cross-node Gson serialization;
replace the gc field with a serializable identifier (e.g. String gcUuid or
String gcClassName) and any minimal state (gcInterval, unit), and update
send/receive flows to reconstruct the GC on the receiver side (use a GC
registry/factory or Spring bean lookup to create the TimeBasedGarbageCollector
such as UpdateVmInstanceMetadataGC instead of serializing
ThreadFacade-containing instances). Locate SubmitTimeBasedGarbageCollectorMsg
(field gc), the send path that calls makeTargetServiceIdByResourceUuid(), and
the message handler that schedules the GC, and change them to pass the
identifier and call your TimeBasedGarbageCollectorFactory/manager to rehydrate
the concrete GC before scheduling.
In
`@header/src/main/java/org/zstack/header/storage/primary/APIRegisterVmInstanceEventDoc_zh_cn.groovy`:
- Around line 10-23: Update the documentation entries for the
APIRegisterVmInstanceEvent: replace the placeholder desc "null" under the ref
block for name "inventory" (path
"org.zstack.header.storage.primary.APIRegisterVmInstanceEvent.inventory", clz
VmInstanceInventory.class) with a concise Chinese description of the
VmInstanceInventory (e.g., “虚拟机实例信息” plus any brief detail), and fill the field
block for name "success" (type "boolean") with a short Chinese description
indicating it denotes whether the operation succeeded (e.g., “操作是否成功”); keep the
descriptions brief and context-appropriate.
In
`@header/src/main/java/org/zstack/header/storage/primary/APIRegisterVmInstanceMsg.java`:
- Around line 26-27: 在 APIRegisterVmInstanceMsg 中，给 metadataPath 明确声明约束并在
__example__ 中填充示例值：将字段上的注解由 `@APIParam`() 改为 `@APIParam`(required = true)
以显式表明必需性，并在类的 __example__ 方法里通过对应的 setter（例如 setMetadataPath(...)）为 metadataPath
赋予一个合理的示例值，确保生成的 API 文档包含所有必填字段的示例。
In
`@header/src/main/java/org/zstack/header/storage/primary/APIRegisterVmInstanceMsgDoc_zh_cn.groovy`:
- Around line 49-57: Add a human-readable Chinese description for the
metadataPath parameter in APIRegisterVmInstanceMsgDoc_zh_cn.groovy by filling
the empty desc field inside the column block for "metadataPath"; mention the
parameter's purpose (path or URL to VM metadata), expected format (e.g.,
absolute path or URL, allowed schemes like http(s) or file, any encoding/size
constraints) and whether it is required, and include since "4.10.0" context —
update the desc to a concise sentence that guides API users on what to provide
and any validation rules.
In `@plugin/kvm/src/main/java/org/zstack/kvm/KVMAgentCommands.java`:
- Around line 4720-4733: Add the `@NoLogging` annotation to the sensitive metadata
fields to prevent them from being written to logs: annotate the 'metadata' field
in class WriteVmInstanceMetadataCmd and the 'metadata' field in class
ReadVmInstanceMetadataRsp with `@NoLogging`, and import the NoLogging annotation
(where other agent DTO annotations are defined) so the serializer/logging
framework will skip these fields.
In `@plugin/kvm/src/main/java/org/zstack/kvm/KVMHost.java`:
- Around line 7382-7388: In the success handler for ReadVmInstanceMetadataRsp
(the anonymous success(ReadVmInstanceMetadataRsp rsp) method), avoid setting
reply metadata when rsp.isSuccess() is false: only call
reply.setMetadata(rsp.metadata) inside the success branch; when rsp.isSuccess()
is false set the error on reply (reply.setError(...)) and do not set metadata
before bus.reply(msg, reply) and completion.done(); update the success(...)
logic accordingly so metadata is only populated on successful responses.
In
`@plugin/localstorage/src/main/java/org/zstack/storage/primary/local/LocalStorageKvmBackend.java`:
- Around line 3800-3824: The code calls findValue() into installPath and
immediately uses replaceFirst causing an NPE if installPath is null; also the
error reply uses self.getUuid() (primary storage) instead of the root volume or
VM id. Update the handle(UpdateVmInstanceMetadataOnPrimaryStorageMsg...) to
check if installPath == null (or blank) before calling replaceFirst; if null,
create an UpdateVmInstanceMetadataOnPrimaryStorageReply, setError using
Platform.operr(...) that references msg.getRootVolumeUuid() (or
msg.getVmInstanceUuid() if available) and include the underlying cause/context,
then bus.reply(msg, reply) and return. Keep the rest of the flow (creating
metadataPath, sending UpdateVmInstanceMetadataOnHypervisorMsg) unchanged.
In
`@plugin/nfsPrimaryStorage/src/main/java/org/zstack/storage/primary/nfs/NfsPrimaryStorage.java`:
- Around line 1928-1951: The handler
handle(UpdateVmInstanceMetadataOnPrimaryStorageMsg) must null-check the backend
returned by getUsableBackend() and should select the backend based on the host
UUID to avoid NPEs and wrong routing; change the logic to call
getHostUuidFromVolume(msg.getRootVolumeUuid()), then obtain a backend via a
host-aware selector (e.g. a new/getBackendForHost(hostUuid) or similar lookup)
instead of blindly using getUsableBackend(), validate that the returned
NfsPrimaryStorageBackend is non-null and return an error reply if it is null,
and only then call backend.handle(msg, hostUuid, new ReturnValueCompletion...).
In
`@plugin/nfsPrimaryStorage/src/main/java/org/zstack/storage/primary/nfs/NfsPrimaryStorageKVMBackend.java`:
- Around line 2052-2067: The callback in
NfsPrimaryStorageKVMBackend.handle(UpdateVmInstanceMetadataOnPrimaryStorageMsg...)
is replying with the wrong reply type and never completing the provided
ReturnValueCompletion; change the CloudBusCallBack to construct and send an
UpdateVmInstanceMetadataOnPrimaryStorageReply and call completion.success(reply)
on success or completion.fail(error) on failure (use the hypervisor MessageReply
error via r.getError()), and stop using
RevertVolumeFromSnapshotOnPrimaryStorageReply or bus.reply(msg, ...) so the
caller's completion is properly resolved and the UUID in error messages is the
vm/primary storage UUID from msg.
In `@storage/src/main/java/org/zstack/storage/primary/PrimaryStorageBase.java`:
- Around line 1870-2134: The registerVmInstance flow chain currently uses only
NoRollbackFlow steps (read-metadata, register-volume, register-snapshot,
register-vmInstance) and persists entities via dbf.persist/dbf.persistCollection
without compensation, leaving stale
VolumeVO/VolumeSnapshotVO/VolumeSnapshotTreeVO/VolumeSnapshotGroupVO/VolumeSnapshotGroupRefVO/VmInstanceVO
rows on failure; change the persisting flows to support rollback by either (a)
switch those NoRollbackFlow instances to Flow and implement rollback handlers
that delete any entities created in that flow (track created VO UUIDs in
flow-local lists) or (b) wrap the whole chain in a single
transactional/compensating flow that deletes all created entities on error (use
the collected created lists from register-volume, register-snapshot,
register-vmInstance and remove via dbf.remove or appropriate DAO methods in the
Flow.rollback), ensuring completion/error handlers remain unchanged so
completion.fail is called on error.
- Around line 1837-1867: The fail branch in handle(APIRegisterVmInstanceMsg msg)
publishes the APIRegisterVmInstanceEvent without setting the error, so callers
may think the operation succeeded; in the
ReturnValueCompletion<VmInstanceInventory>.fail(ErrorCode errorCode)
implementation, call event.setError(errorCode) (or set an appropriate error on
the APIRegisterVmInstanceEvent) before bus.publish(event) and chain.next() so
the failure is propagated back to the caller when registerVmInstance fails.
🧹 Nitpick comments (7)
testlib/src/main/java/org/zstack/testlib/KVMSimulator.groovy (1)
684-691: 建议将超长 JSON 响应外置或构建生成。当前内联字符串过长，维护和阅读成本高；可考虑放到资源文件或用结构化对象再序列化生成。
sdk/src/main/java/org/zstack/sdk/RegisterVmInstanceAction.java (2)
5-5: 冗余的同包导入。
import org.zstack.sdk.*;是冗余的，因为该类本身就在org.zstack.sdk包中。♻️ 建议移除冗余导入
import java.util.HashMap; import java.util.Map; -import org.zstack.sdk.*;
43-47: 建议使用泛型参数化 List 类型。
systemTags和userTags使用了原始类型List，建议参数化为List<String>以提高类型安全性。♻️ 建议的类型参数化
`@Param`(required = false) - public java.util.List systemTags; + public java.util.List<String> systemTags; `@Param`(required = false) - public java.util.List userTags; + public java.util.List<String> userTags;header/src/main/java/org/zstack/header/storage/primary/ReadVmInstanceMetadataOnHypervisorReply.java (1)
5-14: 建议字段命名保持一致性。
ReadVmInstanceMetadataOnHypervisorReply使用字段名metadata，而ReadVmInstanceMetadataReply使用vmMetadata。建议统一字段命名以提高代码可维护性和数据映射的清晰度。♻️ 建议的修改
public class ReadVmInstanceMetadataOnHypervisorReply extends MessageReply { - private String metadata; + private String vmMetadata; - public String getMetadata() { - return metadata; + public String getVmMetadata() { + return vmMetadata; } - public void setMetadata(String metadata) { - this.metadata = metadata; + public void setVmMetadata(String vmMetadata) { + this.vmMetadata = vmMetadata; } }storage/src/main/java/org/zstack/storage/primary/PrimaryStorageBase.java (1)
2138-2185: 反射读取静态字段不应依赖 clazz.newInstance()。
newInstance()已废弃且要求 public 无参构造；对 static 字段可用field.get(null)。建议改为getDeclaredConstructor().newInstance()（并处理异常）或按是否 static 取值。header/src/main/java/org/zstack/header/storage/primary/APIRegisterVmInstanceEvent.java (1)
24-25: 建议与现有 API Event 保持一致的构造函数风格参考
APIReimageVmInstanceEvent的无参构造函数实现：public APIReimageVmInstanceEvent() { super(null); }当前实现虽然功能上没有问题，但建议保持一致性。
♻️ 可选的修改建议
public APIRegisterVmInstanceEvent() { + super(null); }header/src/main/java/org/zstack/header/storage/primary/APIRegisterVmInstanceMsg.java (1)
70-72:__example__()返回空对象，文档示例信息不足。建议填充代表性字段值，提升自动生成的 API 文档可读性与可用性。
♻️ 建议示例填充
public static APIRegisterVmInstanceMsg __example__() { APIRegisterVmInstanceMsg msg = new APIRegisterVmInstanceMsg(); + msg.setZoneUuid(uuid()); + msg.setClusterUuid(uuid()); + msg.setPrimaryStorageUuid(uuid()); + msg.setHostUuid(uuid()); + msg.setMetadataPath("/zstack/metadata/vm-uuid"); return msg; }

潜在的 TOCTOU 竞态条件
在检查 chainInfo.getPendingTask().isEmpty() 和提交 chainSubmit 之间存在时间窗口，其他线程可能在此期间提交任务。不过考虑到这是 GC 场景，偶尔的重复提交不会造成数据一致性问题（因为后续会通过 syncSignature 串行化执行），影响较小。
建议确认这种行为是否符合预期设计。

未校验 root volume installPath，可能触发 NPE。

backend 选择与空值校验缺失，存在 NPE/路由错误风险。
这里直接使用 getUsableBackend() 且无空值检查；若无可用 backend 会直接 NPE。同时建议基于 hostUuid 选择 backend，以避免多 hypervisor 场景走错实现。

回调路径与回复类型不匹配，导致上层永远不完成。
当前实现忽略 completion 且使用了错误的 reply 类型，容易造成上层等待超时，并且错误信息中的 UUID 也不准确。请改为通过 completion.success/fail 传递结果并使用正确的 reply 类型。

注册流程缺少回滚会留下脏数据。
当前全是 NoRollbackFlow，任一步失败都会留下已持久化的 Volume/Snapshot/VM/Group 记录。建议增加可回滚 flow / 补偿删除，或统一事务回滚。

switch those NoRollbackFlow instances to Flow and implement rollback handlers
that delete any entities created in that flow (track created VO UUIDs in
flow-local lists) or (b) wrap the whole chain in a single
transactional/compensating flow that deletes all created entities on error (use
the collected created lists from register-volume, register-snapshot,
register-vmInstance and remove via dbf.remove or appropriate DAO methods in the
Flow.rollback), ensuring completion/error handlers remain unchanged so
completion.fail is called on error.

the codebase that reference org.zstack.compute.vm.metadata to the new package
com.zstack.core.vmmetadata so compilation succeeds.
In `@compute/src/main/java/org/zstack/compute/vm/metadata/ResourceConfigDTO.java`:
- Around line 3-4: ResourceConfigDTO is empty but code calls setConfigKey,
setConfigValue, setIsSensitive from VmMetadataConverter.convertResourceConfig;
add private fields configKey (String), configValue (String) and isSensitive
(boolean) to ResourceConfigDTO and implement corresponding getters and setters
(getConfigKey/setConfigKey, getConfigValue/setConfigValue,
isSensitive/setIsSensitive) so the converter can compile and populate these
values.
In
`@compute/src/main/java/org/zstack/compute/vm/metadata/SensitiveFieldHandler.java`:
- Around line 30-32: The isSensitiveField method currently calls
SENSITIVE_PATTERN.matcher(key) without guarding against null and can throw NPE;
update isSensitiveField(String key) to check for null (or empty) first and
return false (or appropriate non-sensitive default) when key is null before
calling SENSITIVE_PATTERN.matcher(key). Refer to the isSensitiveField method and
SENSITIVE_PATTERN constant to locate the change and add the null check as the
first statement in the method.
- Around line 18-25: SENSITIVE_TAGS is declared but never initialized which
causes a NullPointerException in the static initializer that builds
SENSITIVE_PATTERN; initialize SENSITIVE_TAGS (e.g., as an immutable/empty List
or populated from config) before the static block and guard the regex
construction in the static initializer so it handles an empty list (build a safe
regex or skip Pattern.compile if no tags). Update the static block referencing
SENSITIVE_TAGS and SENSITIVE_PATTERN in SensitiveFieldHandler to use the
initialized list or a fallback to avoid NPEs.
- Around line 3-8: SensitiveFieldHandler is using several types/constants that
are not imported; add import declarations for GlobalConfig,
VM_METADATA_SENSITIVE_KEY, AESCipher, AlertManager, and SystemTagDTO at the top
of SensitiveFieldHandler.java (or the correct packages in your project) so the
compiler can resolve those symbols used in methods of SensitiveFieldHandler and
any references to the VM_METADATA_SENSITIVE_KEY constant, AESCipher encryption
calls, AlertManager alerts, and SystemTagDTO handling.
In `@compute/src/main/java/org/zstack/compute/vm/metadata/SystemTagDTO.java`:
- Around line 3-4: SystemTagDTO is empty but other classes call its
getters/setters; add private fields String tagKey, String tagValue and boolean
isSensitive, and implement the matching public accessors used elsewhere:
getTagKey(), setTagKey(String), getTagValue(), setTagValue(String), and
setIsSensitive(boolean) plus a boolean getter (getIsSensitive() or
isSensitive()) so calls from VmMetadataConverter.convertSystemTag() and
SensitiveFieldHandler compile; keep standard Java bean naming and simple
field-backed implementations inside class SystemTagDTO.
In
`@compute/src/main/java/org/zstack/compute/vm/metadata/VmMetadataConverter.java`:
- Around line 27-139: The convert(...) helpers currently call stream() or
getSnapshotRefs() on input lists/fields that may be null, causing NPEs; update
convert, convertVmNic, convertVolume, convertSnapshot, convertSnapshotGroup (and
any other converter methods) to defensively treat null lists by using
Collections.emptyList() (or Optional.ofNullable(...).orElse(...)) before
streaming, and in convertSnapshotGroup ensure vo.getSnapshotRefs() is
null-checked/empty-defaulted before mapping
VolumeSnapshotGroupRefVO::getSnapshotUuid so snapshotUuidList is an empty list
instead of throwing.
- Around line 1-4: Remove the duplicate package declaration by deleting "package
com.zstack.core.vmmetadata;" so VmMetadataConverter has only the correct
package; add missing imports for VolumeSnapshotGroupRefVO,
VolumeSnapshotReferenceVO, and VolumeSnapshotReferenceTreeVO (use their correct
fully-qualified class names) and remove or replace any references to the
non-existent CoreMemorySnapshotConfigs class (either import the correct
replacement or delete related logic) in the VmMetadataConverter class; and add
null checks before any .stream() calls in the conversion methods (e.g.,
convertVmNic, convertVolume, convertSnapshot and similar converters) to return
an empty collection or handle null input safely to avoid NullPointerException.
In `@compute/src/main/java/org/zstack/compute/vm/metadata/VmMetadataDTO.java`:
- Around line 7-42: VmMetadataDTO currently lacks getter/setter methods and a
serialVersionUID, causing compilation and deserialization failures; add a
private static final long serialVersionUID and implement public JavaBean getters
and setters for every private field declared in VmMetadataDTO (schemaVersion,
createTime, name, description, hypervisorType, guestOsType, architecture,
platform, type, rootVolumeUuid, imageUuid, memorySize, reservedMemorySize,
cpuNum, cpuSpeed, volumeList, nicList, snapshotList, snapshotGroupList,
systemTags, resourceConfigs). Also ensure the DTO exposes the exact accessor
names expected by callers (e.g., provide methods matching usages in
VmMetadataConverter/VmMetadataSerializer such as setVmUuid/getVmUuid and
setNumCpus/getNumCpus or add delegating methods that map to the existing fields)
so JSONObjectUtil and converters can bind properties correctly.
In
`@compute/src/main/java/org/zstack/compute/vm/metadata/VmMetadataSerializer.java`:
- Around line 76-81: The loop in VmMetadataSerializer that decrypts sensitive
fields calls dto.getResourceConfigs().forEach(...) without null-check, causing
NPE; before iterating, guard the call by checking dto.getResourceConfigs() !=
null (or use Optional/Collections.emptyList()) so you only call forEach when the
list is non-null, and keep using SensitiveFieldHandler.isSensitiveField(...) and
SensitiveFieldHandler.decrypt(...) inside the guarded block.
- Around line 62-71: In VmMetadataSerializer, the comparison
storedChecksum.equals(calculatedChecksum) can NPE if storedChecksum is null;
change the check to first handle null (e.g., treat null as mismatch) by
replacing the equality test with a null-safe check (for example: if
(storedChecksum == null || !storedChecksum.equals(calculatedChecksum)) ) so that
getSha256Checksum() being null triggers the same AlertManager.alert and
SecurityException path; reference storedChecksum, getSha256Checksum(),
calculatedChecksum, Sha256Utils.hash and JSONObjectUtil.toJsonString to locate
the code to update.
- Around line 22-31: VmMetadataSerializer.serialize currently calls
dto.getSystemTags() and dto.getResourceConfigs() without null checks which can
cause NPEs; update serialize to null-check VmMetadataDTO.getSystemTags() before
passing to SensitiveFieldHandler.filterSensitiveTags and only call
dto.setSystemTags(...) when non-null (or set an empty list if desired), and
null-check VmMetadataDTO.getResourceConfigs() before iterating: if non-null,
iterate and for each config check
SensitiveFieldHandler.isSensitiveField(config.getConfigKey()) then set
config.setConfigValue(SensitiveFieldHandler.encrypt(config.getConfigValue()));
ensure all accessors (getSystemTags, getResourceConfigs, config.getConfigKey,
config.getConfigValue) are guarded so no method is invoked on null.
- Around line 3-6: The imports in VmMetadataSerializer use the wrong base
packages; replace com.zstack.* imports with the project's canonical packages so
the class imports GlobalConfig from org.zstack.core.config (use
org.zstack.core.config.GlobalConfig), AlertManager from org.zstack.core.alert
(org.zstack.core.alert.AlertManager), and the JSON/codec utilities from
org.zstack.utils (org.zstack.utils.json.JSONObjectUtil and
org.zstack.utils.codec.Sha256Utils) to match project conventions.
In `@compute/src/main/java/org/zstack/compute/vm/metadata/VolumeMetadataDTO.java`:
- Around line 47-53: The class VolumeMetadataDTO is missing the String field
referenced by getPrimaryStorageUuid() and setPrimaryStorageUuid(); add a private
static String primaryStorageUuid declaration (matching the static access in
those methods) alongside the other DTO fields in VolumeMetadataDTO so the getter
and setter compile correctly, and ensure any intended visibility (private) and
default initialization are consistent with the other fields.
- Around line 6-26: All fields in VolumeMetadataDTO (e.g., description, name,
vmInstanceUuid, rootImageUuid, diskOfferingUuid, format, installPath, type,
size, actualSize, deviceId, state, status, createDate, lastOpDate,
lastDetachDate, lastAttachDate, lastVmInstanceUuid, isShareable, volumeQos,
protocol) are incorrectly declared static; change each to an instance field
(remove the static modifier) and convert any static getter/setter methods to
instance methods on VolumeMetadataDTO so each DTO holds independent state; after
that, search for call sites that reference class-level access
(VolumeMetadataDTO.field or VolumeMetadataDTO.getX()) and update them to use an
instance (dto.getX()/dto.setX()) or adjust construction, and run tests to ensure
no serialization/ORM annotations rely on static members.
In `@compute/src/main/java/org/zstack/compute/vm/VmInstanceBase.java`:
- Around line 9489-9499: The code in VmInstanceBase contains a residual
DTO/serializer block referencing undefined symbols (vmUuid, volumeVos,
snapshotVos, groupVos, tagVos, configVos, snapshotDto) and won't compile; either
remove the entire DTO/serializer/supplementSnapshotReference lines (the calls to
VmMetadataConverter.convert, VmMetadataSerializer.serialize and
VmMetadataConverter.supplementSnapshotReference) if metadata serialization is no
longer needed, or properly obtain and declare the missing variables before use
(ensure vmUuid is set to the current VM UUID, populate
volumeVos/snapshotVos/groupVos/tagVos/configVos from the DB or method context,
and get snapshotDto from the snapshot handling code) so the calls in
VmInstanceBase compile and have valid inputs.
In `@header/src/main/java/org/zstack/header/vm/VmMetadata.java`:
- Around line 33-36: The two list fields in VmMetadata—volumeSnapshotGroupVO and
volumeSnapshotGroupRefVO—are named in singular form while their type is List;
rename them to plural (e.g., volumeSnapshotGroupsVO and
volumeSnapshotGroupRefsVO or volumeSnapshotGroupVOs and
volumeSnapshotGroupRefVOs) and update all references/usages (constructors,
getters/setters, JSON/mapping annotations, code that reads/writes these fields)
to use the new names to keep naming consistent with their List semantics; ensure
any serialization names or API contracts are adjusted if needed.
In
`@plugin/localstorage/src/main/java/org/zstack/storage/primary/local/LocalStorageKvmBackend.java`:
- Around line 3814-3824: The CloudBusCallBack currently constructs an
UpdateVmInstanceMetadataOnPrimaryStorageReply but never invokes the provided
ReturnValueCompletion<UpdateVmInstanceMetadataOnPrimaryStorageReply> completion,
so the caller is never notified; inside the CloudBusCallBack.run(MessageReply r)
use completion.success(reply) when r.isSuccess() and completion.fail(...) with
the same Platform-operr-created error when !r.isSuccess(), and then still send
bus.reply(msg, reply) if needed; ensure you reference the existing
UpdateVmInstanceMetadataOnPrimaryStorageReply, CloudBusCallBack, completion
parameter and the current error construction
(Platform.operr(...).withCause(r.getError())) so the completion and bus.reply
behavior are consistent and the caller receives the finish notification.
In `@storage/src/main/java/org/zstack/storage/primary/PrimaryStorageBase.java`:
- Around line 1886-1891: The error message in run(MessageReply r) incorrectly
logs self.getUuid() (PrimaryStorageBase) instead of the VM's UUID; update the
operr call in the failure branch to reference the VM's UUID from the surrounding
VM context (e.g., use the vm instance or VM inventory variable such as
vm.getUuid() or vmInventory.getUuid(), or extract it from VmInstanceSpec/VmSpec
if those are in scope) so the error message correctly identifies the VM; ensure
the chosen VM UUID variable is in scope and compile-clean.

3-9: 接口命名不当：使用了 "Exception" 后缀但并非异常类。根据编码规范，
Exception后缀应保留给实际的异常类（继承自Exception或Throwable）。当前RegisterVmInstanceException是一个普通接口，定义了 VM 注册相关的扩展方法，命名可能造成误解。建议重命名为更能体现其职责的名称，例如：

inputVersion 可能为 null，导致 NPE。
如果 DTO 的 schemaVersion 未设置，input.getSchemaVersion() 返回 null，后续 CURRENT_VERSION.equals(inputVersion) 虽然安全，但 compareVersion(inputVersion, CURRENT_VERSION) 在 Line 88 会因 version1.replace("v", "") 抛出 NPE。

使用 Plexus @Component 和手工 new 实例化导致依赖注入失败，运行时会触发 NPE
VmUuidResolverRegistry 使用的是 Plexus 的 @Component（第 3 行），而非 Spring 的 @Component，Spring 不会将其作为 Bean 管理。同时，VolumeBasedVmUuidResolver 和 ResourceBasedVmUuidResolver 在 init() 方法中通过 new 手工实例化（第 184、190 行），这些解析器虽然依赖 @Autowired private DatabaseFacade dbf，但通过 new 创建的实例无法获得 Spring 注入，dbf 将为 null，导致运行时 NPE。
此外，文件还缺少必要的导入：java.util.Map、java.util.HashMap、javax.annotation.PostConstruct，会导致编译失败。
需要改用构造注入模式：将 dbf 通过构造器参数传入解析器，并在 VmUuidResolverRegistry 中注入 dbf；同时将 @Component 改为 Spring 的实现。

VM UUID 提取逻辑与现有解析机制不一致，可能导致元数据更新遗漏
当前仅反射 getVmInstanceUuid()，失败后回退 getResourceUuid()。对按卷/快照反推 VM 的消息，resourceUuid 可能不是 VM UUID。建议复用 compute/src/main/java/org/zstack/compute/vm/metadata/MetadataImpact.java 中的 VmUuidResolverRegistry，按消息类型解析并支持多 VM UUID 场景。

元数据返回路径绕过序列化安全处理，存在敏感信息暴露风险。

9491 - 9497, The code currently serializes vmDto via
VmMetadataSerializer.serialize into the local variable json but then returns the
raw vmMetadata (JSONObjectUtil.toJsonString(vmMetadata)), bypassing the
serializer and exposing sensitive fields; change the return to use the
already-produced json from VmMetadataSerializer.serialize (i.e., return the
serialized output), and refactor
getResourceSystemTagFromDb/getResourceConfigFromDb paths to stop serializing
SystemTagVO/ResourceConfigVO directly — instead convert those VOs to DTOs and
serialize them with the appropriate serializer used by VmMetadataSerializer
(ensure VmMetadataConverter.supplementSnapshotReference is applied to DTOs
before serialization) so all metadata, tags and resource configs go through the
unified DTO+Serializer pipeline.

around lines 2185 - 2188, PrimaryStorageBase creates and sends
GetVmInstanceMetadataFromPrimaryStorageMsg but handleLocalMessage(...) lacks a
corresponding instanceof branch, causing the message to be treated as unknown;
update PrimaryStorageBase.handleLocalMessage to add an instanceof check for
GetVmInstanceMetadataFromPrimaryStorageMsg (or its handler method name if one
exists) and dispatch it to the existing processing routine (or implement the new
handler) so local messages of type GetVmInstanceMetadataFromPrimaryStorageMsg
are properly handled and routed via the local dispatcher.

metadataPath 字段在升级过程中丢失。
upgradeV10ToV11 方法从 v10.getMetadataPath() 读取值来推断 storageType，但没有将 metadataPath 复制到 v11 对象中。这会导致升级后的 DTO 丢失该字段数据。

移除 SDK 中的 zoneUuid 必填约束，或在服务端消息中补齐该字段。
RegisterVmInstanceAction 把 zoneUuid 设为必填（第 31-32 行），但 APIRegisterVmInstanceMsg 中完全不存在该字段。这导致 SDK 参数与服务端消息契约不一致，SDK 客户端会被迫提供一个服务端无法处理的参数。请统一两侧定义：
- 若服务端无需此字段，移除 SDK 中的
zoneUuid声明； - 若产品需要
zoneUuid，在APIRegisterVmInstanceMsg中添加该字段（含相应的参数校验）。

31 - 33, RegisterVmInstanceAction declares a required field zoneUuid that does
not exist on the server message APIRegisterVmInstanceMsg, causing a contract
mismatch; either remove the zoneUuid declaration (or its required=true
constraint) from RegisterVmInstanceAction in the SDK so the client no longer
sends it, or add a corresponding field zoneUuid with appropriate `@Param`
validation to APIRegisterVmInstanceMsg (and its validation logic) so the server
accepts and validates it—locate the RegisterVmInstanceAction class and the
APIRegisterVmInstanceMsg class and apply one of these two fixes to keep both
sides consistent.

In

- Around line 100-104: The comment for MAX_EXPONENT in
UpdateVmInstanceMetadataGC is inconsistent with the actual value (MAX_EXPONENT =
5); update the comment to reflect 2^5 = 32 and the resulting maximum delay of 10
* 32 = 320s (≈ 5.3 minutes), or if the intent was the larger delay, change
MAX_EXPONENT to 10 and adjust any dependent logic; locate the constant
MAX_EXPONENT in class UpdateVmInstanceMetadataGC and either correct the
explanatory text to match 5 or change the constant to the intended exponent and
update the comment accordingly.
In
`@compute/src/main/java/org/zstack/compute/vm/metadata/VmMetadataUpdateInterceptor.java`:
- Around line 103-106: The comment points out that VmMetadataUpdateInterceptor
currently returns on any API failure without honoring the
`@MetadataImpact`(updateOnFailure) intent; update the logic in
VmMetadataUpdateInterceptor so that when apiEvent.getError() != null you look up
the pendingApis entry for apiEvent.getApiId() (or otherwise obtain the
MetadataImpact) and only return if impact.updateOnFailure() is false; otherwise
continue processing the failed API event. Ensure you reference the pendingApis
lookup and the MetadataImpact (or annotation wrapper) and call updateOnFailure()
to decide whether to skip or proceed.
- Around line 84-85: Remove the unused dead field by deleting the level field
from the MetadataImpactInfo class and its assignment in the constructor so the
class only stores vmUuid and whatever value is actively used; then implement the
comment's intended behavior in VmMetadataUpdateInterceptor by honoring the
MetadataImpact annotation's updateOnFailure flag: when an API fails, check the
MetadataImpact.updateOnFailure() value on the msg class (same annotation you
already read when creating MetadataImpactInfo) and only skip processing if
updateOnFailure is false—adjust the failure-handling path that currently always
skips pendingApis to consult this flag (you can add the flag to
MetadataImpactInfo if needed) so failed APIs with updateOnFailure=true still
trigger metadata updates.
In `@compute/src/main/java/org/zstack/compute/vm/VmInstanceBase.java`:
- Around line 9400-9403: The current run(SyncTaskChain chain) calls
doHandleUpdateVmInstanceMetadata(msg) then immediately invokes chain.next(),
which breaks the intended per-VM serialization because
doHandleUpdateVmInstanceMetadata performs an asynchronous bus.send(...); fix by
making run defer chain.next() until the async work completes — i.e., change
doHandleUpdateVmInstanceMetadata(msg) (or the block that calls bus.send) to
accept a completion callback/future and invoke chain.next() in the bus.send
reply handler (or when that future completes); ensure chain.next() is removed
from the synchronous path and only called from within the bus.send callback or
completion handler so subsequent tasks for the same VM run only after the async
update finishes.
In `@core/src/main/java/org/zstack/core/gc/GarbageCollector.java`:
- Around line 203-219: The triggerGC() path has two issues: a potential NPE when
dbf.findByUuid(...) returns null before calling vo.getStatus(), and an
inconsistent claim condition versus loadFromVO() which expects
managementNodeUuid IS NULL; update triggerGC() to null-check the returned
GarbageCollectorVO from dbf.findByUuid(...) before accessing vo.getStatus(), and
when loading the VO for manual trigger either add
.isNull(GarbageCollectorVO_.managementNodeUuid) to the query or explicitly
verify vo.getManagementNodeUuid() == null before calling loadFromVO(); ensure
that if loadFromVO() returns false you do not call runTrigger() on an
uninitialized GC (i.e., only call setup()/prepare()/runTrigger() when the VO was
successfully claimed and loadFromVO() returned true).

Duplicate comments:
In `@compute/src/main/java/org/zstack/compute/vm/VmInstanceBase.java`:
- Around line 9413-9416: The code in VmInstanceBase that queries the root volume
using Q.New(VolumeVO.class)...findTuple() assigns tuple.get(...) directly to
primaryStorageUuid and rootVolumeUuid and can NPE if no root volume is found;
update the logic to check whether the returned tuple is null (or empty) after
findTuple() and handle that case by returning a proper error response or
throwing a readable exception instead of dereferencing the tuple (references:
VolumeVO_, VolumeVO_.vmInstanceUuid, VolumeType.Root, tuple, msg.getUuid,
primaryStorageUuid, rootVolumeUuid); ensure the error path logs context (vm
UUID) and stops further processing.
- Around line 9497-9507: The block uses undefined symbols (vmUuid, volumeVos,
snapshotVos, groupVos, tagVos, configVos, snapshotDto) and an unimported
VmMetadataSerializer; fix by sourcing/declaring the missing variables from the
surrounding method or passing them as parameters (e.g., use the VmInstanceVO
instance’s getUuid for vmUuid, retrieve or compute
volumeVos/snapshotVos/groupVos/tagVos/configVos the same way other callers in
VmInstanceBase do, and obtain snapshotDto from the snapshot processing context),
and add the missing import for
org.zstack.compute.vm.metadata.VmMetadataSerializer; update calls accordingly
(VmMetadataConverter.convert(...) and VmMetadataSerializer.serialize(...)) so
all referenced symbols exist in this method scope.
- Around line 9502-9508: The code calls VmMetadataSerializer.serialize(vmDto)
but then returns JSONObjectUtil.toJsonString(vmMetadata), discarding the
sanitized json and bypassing sensitive-field handling; update the return to use
the serialized result from VmMetadataSerializer.serialize(vmDto) (the local
variable json) and ensure any serialization of SystemTagVO/ResourceConfigVO uses
the same DTO/serializer pipeline instead of direct JSONObjectUtil.toJsonString
on raw VO objects; adjust the logic around
VolumeSnapshotReferenceVO/dbf.findByUuid and
VmMetadataConverter.supplementSnapshotReference(snapshotDto, refVo) to operate
on the DTOs prior to calling VmMetadataSerializer.serialize so sensitive fields
are preserved by the serializer.

level 字段存储后未使用，属于死代码
MetadataImpactInfo 的 level 字段在构造函数中赋值（第 195 行），但在整个类中从未被引用。建议删除此字段。
此外，第 103-105 行的注释提到应支持 @MetadataImpact(updateOnFailure=true) 来在 API 失败时仍进行更新，但当前代码并未实现此逻辑检查，总是在出错时直接跳过，与注释说明不符。

updateOnFailure 属性注释与实现不一致
注释提到 @MetadataImpact(updateOnFailure=true) 应允许 API 失败时仍触发更新，但代码直接 return 跳过了所有失败的 API，未读取或检查该属性。
若该功能暂不实现，建议移除注释中的 updateOnFailure 描述以避免混淆；否则需补充逻辑：
MetadataImpact impact = pendingApis.get(apiEvent.getApiId())...;
if (apiEvent.getError() != null && !impact.updateOnFailure()) {

修复 triggerGC() 中的空指针风险和认领条件不一致。
手动触发路径存在两个问题：
-
空指针风险（第 321 行）：
dbf.findByUuid()在找不到记录时可能返回 null，但第 322 行直接调用vo.getStatus()无 null 检查。 -
认领条件不一致：孤儿加载明确要求
managementNodeUuid IS NULL（行 206-207），但手动触发的triggerGC()无此过滤。若传入已被其他节点认领的 GC 记录，loadFromVO()会因乐观锁失败而返回 false，导致 GC 未被正确初始化（setup()/prepare()未执行），但仍会继续调用runTrigger()，在未初始化对象上执行可能导致问题。
建议：
- 第 321 行添加 null 检查
triggerGC()获取 VO 时加上.isNull(GarbageCollectorVO_.managementNodeUuid)条件，或在调用前验证该字段为 NULL
