Today, I found this gem here in the codebase I've taken over:
#define BYTE unsigned char
FFS, use typedef, it's there for a reason. Solving the puzzle in the first comment.6 -
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>
#include <sys/time.h>
void setDate(const char* dataStr) // format like MMDDYY
{
char buf[3] = {0};
strncpy(buf, dataStr + 0, 2);
unsigned short month = atoi(buf);
strncpy(buf, dataStr + 2, 2);
unsigned short day = atoi(buf);
strncpy(buf, dataStr + 4, 2);
unsigned short year = atoi(buf);
time_t mytime = time(0);
struct tm* tm_ptr = localtime(&mytime);
if (tm_ptr)
{
tm_ptr->tm_mon = month - 1;
tm_ptr->tm_mday = day;
tm_ptr->tm_year = year + (2000 - 1900);
const struct timeval tv = {mktime(tm_ptr), 0};
settimeofday(&tv, 0);
}
}
int main(int argc, char** argv)

I really hate PHP frameworks.
I also often write my own frameworks but propriety. I have two decades experience doing without frameworks, writing frameworks and using frameworks.
Virtually every PHP framework I've ever used has causes more headaches than if I had simply written the code.
Let me give you an example. I want a tinyint in my database.
> Unknown column type "tinyint" requested.
Oh, doctrine doesn't support it and wont fix. Doctrine is a library that takes a perfectly good feature rich powerful enough database system and nerfs it to the capabilities of mysql 1.0.0 for portability and because the devs don't actually have the time to create a full ORM library. Sadly it's also the defacto for certain filthy disgusting frameworks whose name I shan't speak.
So I add my own type class. Annoying but what can you do.
I have to try to use it and to do so I have to register it in two places like this (pseudo)...
Types::add(Tinyint::class);
Doctrine::add(Tinyint::class);
Seems simply enough so I run it and see...
> Type tinyint already exists.
So I assume it's doing some magic loading it based on the directory and commend out the Type::add line to see.
> Type to be overwritten tinyint does not exist.
Are you fucking kidding me?
At this point I figure out it must be running twice. It's booting twice. Do I get a stack trace by default from a CLI command? Of course not because who would ever need that?
I take a quick look at parent::boot(). HttpKernel is the standard for Cli Commands?
I notice it has state, uses a protected booted property but I'm curious why it tries to boot so many times. I assume it's user error.
After some fiddling around I get a stack trace but only one boot. How is it possible?
It's not user error, the program flow of the framework is just sub par and it just calls boot all over the place.
I use the state variable and I have to do it in a weird way...
> $booted = $this->booted;parent::boot();if (!$booted) {doStuffOnceThatDependsOnParentBootage();}
A bit awkward but not life and death. I could probably just return but believe or not the parent is doing some crap if already booted. A common ugly practice but one that works is to usually call doSomething and have something only work around the state.
The thing is, doctrine does use TINYINT for bool and it gets all super confused now running commands like updates. It keeps trying to push changes when nothing changed. I'm building my own schema differential system for another project and it doesn't have these problems out of the box. It's not clever enough to handle ambiguous reverse mappings when single types are defined and it should be possible to match the right one or heck both are fine in this case. I'd expect ambiguity to be a problem with reverse engineer, not compare schema to an exact schema.
This is numpty country. Changing TINYINT UNSIGNED to TINYINT UNSIGNED. IT can't even compare two before and after strings.
There's a few other boots I could use but who cares. The internet seems to want to use that boot function. There's also init stages missing. Believe it or not there's a shutdown and reboot for the kernel. It might not be obvious but the Type::add line wants to go not in the boot method but in the top level scope along with the class definition. The top level scope is run only once.
I think people using OOP frameworks forget that there's a scope outside of the object in PHP. It's not ideal but does the trick given the functionality is confined to static only. The register command appears to have it's own check and noop or simply overwrite if the command is issued twice making things more confusing as it was working with register type before to merely alias a type to an existing type so that it could detect it from SQL when reverse engineering.
I start to wonder if I should just use columnDefinition.
It's this. Constantly on a daily basis using these pretentious stuck up frameworks and libraries.
It's not just the palava which in this case is relatively mild compared to some of the headaches that arise. It's that if you use a framework you expect basic things out of the box like oh I don't know support for the byte/char/tinyint/int8 type and a differential command that's able to compare two strings to see if they're different.
Some people might say you're using it wrong. There is such a thing as a learning curve and this one goes down, learning all the things it can't do. It's cripplesauce.12 -
I have, once again, figured out why I keep dropping C as a language. The answer is because the errors are incredibly unhelpful and actively want to implode your brain.
Examples currently being spat out by gcc for my driver:
`error: conflicting types for ‘block_read’; have ‘ssize_t(struct file *, char *, size_t, loff_t *)’ {aka ‘int(struct file *, char *, unsigned int, long long int *)’}`
`note: previous declaration of ‘block_read’ with type ‘ssize_t(struct file *, char *, size_t, loff_t *)’ {aka ‘int(struct file *, char *, unsigned int, long long int *)’}`
`error: initialization of ‘ssize_t (*)(struct file *, char *, size_t, loff_t *)’ {aka ‘int (*)(struct file *, char *, unsigned int, long long int *)’} from incompatible pointer type ‘ssize_t (*)(struct file *, char *, size_t, loff_t *)’ {aka ‘int (*)(struct file *, char *, unsigned int, long long int *)’}`
Go character by character for those types as listed, and tell me where they differ, because I can't find it.10 -
A bit longer rant, somehow triggered by the end of this rant:
https://devrant.com/rants/7145365/...
The discussion revolved around strpos returning false or a positive integer.
Instead of an Option or a Exception.
I said I'm a sucker for exception, but I'm also a sucker for typing.
Which is something most languages lack - except the lower level ones like C / C++.
I always loved languages which have unsigned and signed types.
There, I said it... :) I know that signed / unsigned is controversial, Google immediately leads to blog entries screaming bloody murder because unsigned can overflow – or underflow, if someone tries to use a -1on an unsigned integer.
Note that my love is only meant for numeric types, unsigned / signed char is ... a whole can of insanity on its own.
https://phoronix.com/news/...
If you wanna know more.
Back to the strpos problem, now with my secret love exposed:
strpos works on a single string, where a string is a sequence of chars starting with 0.
0 is a positive integer.
In case the needle (char that should be looked up in the string) cannot be found in the haystack (the string), PHP returns "false".
This leads to the necessity of explicitly checking the type as "0" (beginning of string, a string position)... So strpos !== false.
PHP interprets 0 as false, any other integer value is true.
In the discussion, the suggestion came up to return -1 if a value could not be found – which some languages do, for example Scala.
Now I said I have a love for unsigned & signed integers vs. just signed integers...
Can you guess why the -1 bothers me very much?
Because it's a value that's illogical.
A search in a sequence that is indexed by 0 can only have 0 or more elements, not less than zero elements.
-1 refers to a position in the sequence that *cannot* exist.
Which is - of course - the reason -1 was chosen as a return value for false, but it still annoys me.
An unsigned integer with an exception would be my love as a return value, mostly because an unsigned integer represents the return value *best*. After all, the sequence can only return a value of 0 ... X.
*sigh*
Yes, I know I'm weird.
I'm also missing unsigned in Postgres, which was more or less not implemented because it's not in the SQL standard...
