* using our new domain name for preview

* install python package error

* don't build doc default

* refactor check_pr_approval, allow using github login-id

2. remove the tricks for paddle.fluid.layers.ops.func

* add testcases

* simplify the test data, and added to file diff approvals

* remove a approver

* test_print_signatrues runs on a simple pipeline, no paddle installed

* testcases for print_signatrures and sampcd . python3 only.

* remove unused import directives

* remove unused import directives

* using argparse to handle selections

* 2 TODOs

* 先不更改pipeline配置，这里强制改成GPU版本

* sorted the all_names

* exec gpu sample codes tests incrementally

* get all apis from the pr.spec file

* condition with WITH_GPU

WITH_GPU == ON

save

* delete the useless codes

* delete the useless codes.

test=document_fix

* echo the diff result

test=document_fix

* dont reuse the variables

* rename fun to _func not work. put it into the skiplist

https://github.com/PaddlePaddle/Paddle/commit/038ffc795025170e8cda74bcd473b46301b9a1c0
test=document_fix

* skip it in check api approvals

test=document_fix

save

* skip the private _variables

* print signatures wrong. now rename it to _func

test=document_fix

* 增加方法获取和执行全量api的示例代码进行测试

* start the sample code test for gpu

* should import paddle separately

* add a stdout handler, the default is stderr. the paddle_build.sh will catch the stdout content.

* add RUN_ON_DEVICE into the requires set

* if codeblok['required'] is empty, use the RUN_ON_DEVICE instead

* set the threads to 16

http://agroup.baidu.com/paddlepaddle-org-cn/md/article/4036225

* 设置默认日志级别为INFO级别

* using the logic from gen_doc.py

* using modulelist to get the all apis

* as we don't care which name is the shorttest, so fetch the first name in the all_names list

* the new list from project

* 先不启用gpu测试，先把print_signature获取不到全部API的问题解决了

use the `required` instruction to determine if the environment fits the sample code's required. (#32766)

* add unittests

* add find_last_future_line_end

* extract_code_blocks_from_docstr and its testcases

* test_codeblock_before_examples_is_ignored

* sampcd_extract_to_file 拆为两步

* update the codeblock element's format

* code-block directive has no value options

* insert the CODES_INTERTED_INTO_FRONTEND

* using the new func insert_codes_into_codeblock

* get_test_capacity and is_required_match

* using the new funcitons in sampcd_extract_to_file

* add some comments and refactor functions

* using logger instead of all the print

* remote wlist

* collect summary info, and print them

* call get capacity

* update summary format

* print the apis that don't have sample codes.

* print the samples the consumed time more than 10s.

print time

* update unittest testcases

* solve ResourceWarning: unclosed file

* run tools test seperately

* python2 does not have nonlocal keyword, using dict variable instead

* remove unused import, rearrange a series of conditional statements.

* remove wlist.json and its check approval

* remove wlist.json and its check approval

* update testcases

* remove unused codes

* update the docstring for samcd_processor

* no need to import the six module

* 我也不知道为何有一个前导空格，但现在有单元测试，取消这个空格没啥问题

* add unittests for print_signatures; add the first case for 'required' mechanism when executing sample code testing

* there is no paddle installed in PR-CI-APPROVAL

test=document_fix

* print the real name for Functions instead of the ArgSpec

class function method

* some API's name is not __module__ + __name__

so, we disard them temporarily.

* update the logging format for console

* ommit the top level of paddle package.

* these APIs have been removed.

test=document_fix

* Another Error occerd

* print_signatures.py 's stdout is redirect to spec file, so should not print any other info.

so sad.

* print the error msg to stderr

* disable the __init__ magic method

* update unittest for sampcd_processor.py

update unittest for sampcd_processor.py

* PR-CI-APPROVAL 's python interpreter name is not 'python3'.

it's a python3.9;
it does not have paddle installed yet.

此句在CI流水线竟然不可以用。报python3找不到
此句在CI流水线竟然不可以用。因为环境没有安装paddle

* testing only extract api from __all__

paddle module(the top module) does not have __add__
test=document_fix

* should import paddle here

* update the mechanism of extractiong and executing for the sample-codes test.

更新抽取代码和执行代码的逻辑
优化输出打印

* good code style

* get_api_md5 should prefer use the real name rather than the alias names

* case for ArgSpec style. update the unittests

test=document_fix
