About
|
|
====
|
|
qswiki is a wiki software, intended for small wikis. Originally
|
|
implemented in C, it's now written in C++.
|

History
|
|
====
|
|
A couple of years ago, I wanted to setup a personal wiki on my raspberry
|
|
pi. However, the distribution I used back then did not have a PHP package
|
|
for ARM. So I decided I would write one in C. Yes, that's an odd way
|
|
to approach the problem and indeed, I may have had too much time back
|
|
then. Also, I wanted to see how it's like to write a "web app" in C
|
|
and wanted to sharpen my C a little bit.
|
|
|
|
Of course, it's pretty straightforward at first. No really. Just use CGI.
|
|
And indeed, that's probably more than enough. Then I decided to play
|
|
around and started using FastCGI (with the official library from now
|
|
defunct fastcgi.com) and created a multi-threaded version. It initially
|
|
used a "pile of files database", but that became too painful, so then
|
|
I started using sqlite.
|
|
|
|
C++
|
|
---
|
|
Eventually the code became unmaintainable. Initially, I wanted something
|
|
quick. I did not care about memory leaks (as it was CGI initially).
|
|
After FastCGI, they became an issue. In the end, the task of avoiding
|
|
memory leaks became too annoying. And of course, C does not include any
|
|
"batteries" and while I could manage, this too was another good reason.
|
|
|
|
Overall, I am just continuing the experiment with C++17 now. It's not
|
|
nearly as bad as you would expect perhaps. Some things are surprisingly
|
|
convenient even. Still, the standard library is lacking and
|
|
I would hope for a some better built-in Unicode support in the future.

Features
|
|
========
|
|
To be fair, at this point it doesn't even have a "diff" between revisions
|
|
yet and does not have features that make you prefer it over other wikis.
|
|
|
|
- CGI
|
|
- HTTP server using the header only library cpp-httplib. It's more
|
|
portable and more "future-proof" than FastCGI (since the official website
|
|
disappeared, the library's future appears to be uncertain).
|
|
- Support for user accounts. Passwords are stored using PBKDF2.
|
|
sqlite database, but not too much of an effort to add other types of
|
|
storage backends. sqlite is using the great header only library
|
|
sqlite_modern_cpp
|
|
- Relatively fine-grained permission system.
|
|
- Categories
|
|
- Templates
|
|
- FTS search
|
|
- Caching
|
|
|
|
Security
|
|
========
|
|
The most reasonable way would have been to add some sort sandboxing
|
|
support right away, but this is lacking so far. As for "web security",
|
|
all POST requests are centrally protected against CSRF attacks and all
|
|
input is escaped against XSS attacks.
|
|
|
|
Building
|
|
========
|
|
Dependencies:
|
|
- cpp-httplib: https://github.com/yhirose/cpp-httplib
|
|
- SqliteModernCpp: https://github.com/SqliteModernCpp
|
|
|
|
Given the fact those are header-only libraries, they are already
|
|
included here, so you only need to run:
|
|
|
|
```make release```
|
