* Fix judger/log/
* fix(judger): Let judger work on ubuntu 20.04
Judger stops working since 9a6f16cf1d, this commit allows judger continue working.
* fix(web): update faq.php
Let's welcome brand new look made by Bootstrap 4!
Not only website but also our logo is being flat now.
The new logo uses blue as main color, to be different from original.
For us, it also shows the project has up to a new stage.
We hope that the project will get better and better.
BREAKING CHANGE: The path for users to place their images is renamed.
Logos are saved as new names too. Users should move "pictures" to "images".
Any modifications should suit the Bootstrap 4's standard.
There are some situations that need to place subfolder in data path.
If there is any file but not only folder in path, do not move.
Previous moving logic did not check about this.
The runtime versions on faq page are very old and not edited.
If judger is not with web, we can't determine the exact version.
So set these versions as default show, won't be too much different.
We add a new way to access blog page. Now there are 3.
The switch now uses number to choose the way.
1 is for subdomain and 3 is for subfolder.
2 is for separated blog domain with its subfolder.
For example, mike's link is blog.xxx.xxx/mike.
Blog list page link on navbar will change by domain mode.
When using sub-directory blog, the 'blogof' not looks so good.
And, there are duplicate 'blog' characters, which making people uncomfortable.
So, for sub-directory blog, use 'blog' instead of 'blogof'.
'blog' is not as a sub folder or type anymore, use 'post' instead.
BREAKING CHANGE: Due to the conflict of 'blog' sub-directory, when go to blog post,
now should use 'blogs/{id}'; but when subdomain mode is on, you can still use 'blog'
to access these blog posts. 'blogof' is no longer used, and you need to inform users
that blog link is changed, to avoid the inaccessbility.
The web interface is merged but the table is not.
Merge it into a single SQL file, without execute PHP.
Redumped database structure with mysqldump command.
Java 7 is now out of support. A large number of people use Java 8.
As the latest Java LTS version, now add support for Java 11.
Due to the policies from Oracle, SunJDK is replaced.
Upgrade judge_client from Python 2 to Python 3.
Add back and support a new judger update method.
Remove the Makefile outside of the folder which not contain any C file.
