Embodiment
Embodiment 1; A kind of method for upgrading software that can interdepartmental system comprises the steps:
1) definition upgrading supporting paper is made AKU with wrapper on the software systems of redaction.
2) carry out escalation process in system to be upgraded, this process reads AKU, and checks integrality, legitimacy, the applicability of bag.
3) escalation process carries out updating operation according to AKU information, may comprise increasing, delete, replacing of file, the startup of process, stop, and the restarting of system, and the system state of per step operation change is carried out necessary record and backup.
4) updating result is exported; If occur unusually in the escalation process, with the state of system recovery to the upgrading, otherwise upgrade version information, remove backup information.
For realizing desired versatility of the present invention and robustness, the key point of layout strategy and each step is as follows:
Upgrading is divided into packing process and escalation process two parts, respectively corresponding step 1) and step 2) 3) 4).Packing process is finished the making of AKU, and escalation process is finished the upgrading of system to be upgraded and upgraded.The software of these two processes is realized going for different software systems, does not need to develop again for different systems.And in each step of upgrading, only need the simplest manually-operated, can reduce the probability of the complexity and the mistake of packing work like this.
Great majority upgradings necessary operations can reduce the orderly combination of following child-operation: the increasing, delete, replace of file the startup of process, stops the restarting of system.So escalation process just can satisfy most demands as long as support these operations.In order to satisfy versatility, the escalation process program must not comprise the hard coded to concrete filename and path, All Files name and increase, delete, change operation accordingly and all be included in the AKU as configuration information.After escalation process is obtained AKU,, carry out concrete updating operation according to operation description and the routing information in the AKU.
AKU as follows to structure greatly,
Rise Magic string
Level AKU structure version
The MD5 checksum of bag AKU file
Right hardware number of types
Portion's right hardware list of types
Divide the suitable software number of types
The suitable software list of types
Software version number to be upgraded
Upgrading back software version number
Interior upgrade file number
Appearance upgrade step 1) description head
The file data that portion's step 1) needs
Branch upgrading step 2) description head
Step 2) file data of Xu Yaoing
…
The as follows to structure greatly of head described,
Action type
One of following operation: file increases, deletes, replaces, and the startup of process, stops, and system restarts;
Treat the operation file path, or process title and corresponding execution route, execution parameter, file path;
File size, effective when operand is file;
File attribute, effective when operand is file;
File MD5, effective when operand is file;
In step 2) in, escalation process at first is decrypted and decompress(ion) AKU, again according to information such as the check code of AKU head part and versions, detects integrality, legitimacy, the applicability of AKU.Wherein concrete enciphering and deciphering algorithm, compression method, version prescriptive procedure can be grasped flexibly by specific implementation.
In step 3), what escalation process read upgrade step one by one respectively describes head, according to the content of describing head, operates accordingly.Before operating, need to preserve current system state, before file delete, preserve this document content and path, before the process initiation, preserve process corresponding file path, execution route, execution parameter.Finish when the operation that all description heads are described, enter next step, or unusual when certain step operation appearance, enter next step.
In step 4),, and upgrade version information if the backup information that step 3) generates is then removed in the step 3) success.Otherwise according to each step system state of preserving in the step 3), reverse recovery system step by step is to the preceding state of upgrading.
In step 1), need the artificial upgrading supporting paper that generates a text, this document is described this upgrading needs those operations.Carry out packing process again, packing process can read this upgrading supporting paper and generate AKU automatically.Here need the manual reason of writing upgrading supporting paper to be, because this escalation process is general, so escalation process and packing process itself do not know which operation system upgrade relates to, and needs the people to instruct.This supporting paper itself is very simple, need carry out increasing, delete, replacing of which file as long as describe, and the startup of process, stops, and system's reboot operation gets final product.File layout can be grasped flexibly according to specific implementation.
In order farthest to realize versatility, the escalation process program should be self-contained in addition, does not have the dependence to dynamic link library or other external program, configuration.
Embodiment 2;
Suppose that certain software systems needs upgrade-system master routine A, owing to be system's master routine, when upgrading was carried out, the A program necessarily was in running status on machine to be upgraded.And the path of this program file is/usr/opt/bin/A that execution route is/usr/opt/bin no execution parameter.
Can determine that then escalation process needs the following step,
1. the A process of the current operation of halt system.
2. replace the A program file.
3. start the A process.
A kind of method for upgrading software that can interdepartmental system comprises the steps:
Step 1.
The manual upgrading supporting paper following (sample file that is used for illustrative, actual format and key word can be adjusted flexibly) that generates:
########################
Stop?A /usr/opt/bin
Replace?/usr/opt/bin/A
Start?A?/usr/opt/bin
########################
Operation packing process program, this program is squeezed into AKU with program file A automatically according to the supporting paper content, generates 3 and describes head and the packet header of upgrading, and compresses at last and encrypts.
Step 2.
Escalation process is obtained AKU, and deciphering decompresses, and deletes original AKU.Judge this inclusion method according to upgrading packet header.
Step 3.
According to describe head carry out in order stop, the operation of replacement, start-up routine A, in per step implementation, the process name and the execution route of the file path of the process name that stops of record and execution route, replacement and early version file content, startup respectively.
Step 4.
If the record and the backup information that keep are then removed in step 3 success in per step operation, the AKU file behind the removing decompress(ion) returns success information.If step 3 failure is failed when suppose in the end a step start-up routine A, operation note and the early version file content of preserving according to first two steps then, recovery early version file and with its startup returns failure information at last.
This process can be as Fig. 1, shown in 2.
