1. Problems with EDB

With this small program:

include std/eds.e 
include std/io.e 
include std/text.e 
 
db_create("Test.edb",DB_LOCK_NO) 
db_create_table("Table1",DB_LOCK_NO) 
 
 
atom fn 
object KeyName 
sequence Data1, Data2, Data3 
integer result 
sequence file_name  
 
	fn = open("Test1.txt","r") 
	 
	while 1 do 
		KeyName = gets(fn) 
		if atom(KeyName) then 
			exit 
		end if 
		KeyName = KeyName[1..$-1] 
		Data1 = gets(fn) 
		Data1 = Data1[1..$-1] 
		Data2 = gets(fn) 
		Data2 = Data2[1..$-1] 
		Data3 = gets(fn) 
		Data3 = Data3[1..$-1] 
		if db_find_key(KeyName) < 0 then 
			result = db_insert(KeyName,{Data1,Data2,Data3}) 
			printf(1,"db_insert: %d\n",result) 
		end if 
	end while 
	close(fn) 
 
while get_key() != 'n' do end while 

I get this error:

c:\Euphoria\include\std\eds.e:2181 in function db_insert() 
repetition count must not be less than 0 
 
... called from C:\Users\evanmars\Programming\Eu\Programs\EuBrew\TestDB.ex:30 
 
--> See ex.err 
 
 
Press Enter... 

Test1.txt contains:

Key1
Data1
Data2
Data3
Key2
Data4
Data5
Data6
Key3
Data7
Data8, Data9
Data10
Key1
Data1
Data2
Data3

Yes. Although not strictly a bug, we can do better. I'd propose that if the parameter supplied is less than 1, then the library should use DEF_INIT_RECORDS.

Thanks guys. I couldn't see that error, even when I compared this to a previous piece of code that I had written that did work. Probably because I "knew" that part was right, the difference didn't even register in my feeble brain.

I've run into this same problem (repetition count must not be less than 0).

Frankly, I don't know how to apply the patch to eds.e

Should I be downloading a new one, and if so, where from. I'm using that obtained in euphoria-4.1.0-OSX-x64.

Or should I manually edit the file, replacing the lines '-' with the lines '+'?

That seems to have sorted things out, many thanks.

Excellent! Look forward to it.

Any problems I've had with eds, although rare, have been where I have been careless with locking and inadvertently allowed two programs to write to the database at the same time. Errors are rare, but when there are programs running for days, there have to be conflicts.

When I have fixed such situations, there have been no integrity errors at all.
