Problem with Time64 (uint64_t) & "struct ASN__PRIMITIVE_TYPE_s" about asn1c HOT 10 OPEN

Hi @yadav9997,

Problem with Time64 (uint64_t) & "struct ASN__PRIMITIVE_TYPE_s"

What is the exact problem?

which of the below conversion routines (from INTEGER.h) could be you used for the Uint64

You can use the uintmax_t variants.

from asn1c.

@velichkov Thanks a lot for the feedback.

I tried using the asn_umax2INTEGER(INTEGER_t i, uintmax_t l) for long long variable [as below example for Millisecond], when tried to print it only printed 10 digits not the 13 digits and also gave UPER encode error as " value too large "
Millisecond = INTEGER (0..4398046511103);

i am trying to assign 13 digit value and then do UPER encode of this value.
asn_encode_to_new_buffer(0,ATS_UNALIGNED_BASIC_PER, &asn_DEF_MessageFrame, msgf);

Example:
uintmax_t v2 = 1718192021234;
printf("size=%d, value=%ju\n",sizeof(v2),v2);
asn_umax2INTEGER(&millisecond, v2);

from asn1c.

printf("size=%d, value=%ju\n",sizeof(v2),v2);

What are the size and value? Which architecture are you using - x86, x86_64, arm ... ? Which asn1c do you use, from which repository, branch, commit?

What asn1c parameters did you use to compile your asn1 files - -fwide-types, .... ?

asn_umax2INTEGER(&millisecond, v2);

Check the return value of asn_umax2INTEGER

Returns 0 if it was possible to convert, -1 otherwise.
-1/EINVAL: Mandatory argument missing
-1/ERANGE: Value encoded is out of range for long representation
-1/ENOMEM: Memory allocation failed (in asn_*2INTEGER()).

from asn1c.

@velichkov
Apologies for delay in response.

please find below information:

• Architecture is arm [arm-openwrt-linux-gnueabi] for Device [armv7l GNU/Linux]
• v0.9.29 of asn1c
• Actually i am using the Makefile for compilation than using the asn1c command line with -fwide-types parameters. please find below Makefile link:
  https://github.com/mouse07410/asn1c/blob/vlm_master/examples/sample.source.J2735/Makefile
• asn_umax2INTEGER returns as 0
• But when i add the "asn_check_constraints" it shows as below error on the arm device:
  MessageFrame constraint validation failed: Millisecond: value too large (Millisecond.c:26)

Below is the function of Millisecond.c.26 where "value too large" is being printed
int
Millisecond_constraint(const asn_TYPE_descriptor_t *td, const void *sptr,
asn_app_constraint_failed_f *ctfailcb, void *app_key) {
const INTEGER_t *st = (const INTEGER_t *)sptr;
long value;

if(!sptr) {
	ASN__CTFAIL(app_key, td, sptr,
		"%s: value not given (%s:%d)",
		td->name, __FILE__, __LINE__);
	return -1;
}

if(asn_INTEGER2long(st, &value)) {
	ASN__CTFAIL(app_key, td, sptr,
		"%s: value too large (%s:%d)",
		td->name, __FILE__, __LINE__);
	return -1;
}

if((value >= 0 && value <= 4398046511103)) {
	/* Constraint check succeeded */
	return 0;
} else {
	ASN__CTFAIL(app_key, td, sptr,
		"%s: constraint failed (%s:%d)",
		td->name, __FILE__, __LINE__);
	return -1;
}

}

please let me know if anything more information is needed, thanks alot @velichkov

from asn1c.

@velichkov apologies for following up, any possible feedback ?

from asn1c.

* Architecture is arm [arm-openwrt-linux-gnueabi] for Device [armv7l GNU/Linux]

So it is 32bit. Can you reproduce this on 32bit x86 processor or 64bit (arm or intel)?

* v0.9.29 of asn1c

Which repository and commit?

* Actually i am using the Makefile for compilation than using the asn1c command line with -fwide-types parameters. please find below Makefile link:
  https://github.com/mouse07410/asn1c/blob/vlm_master/examples/sample.source.J2735/Makefile

Do you have the same problem with vlm_master branch of mouse07410's fork?

* asn_umax2INTEGER returns as 0

OK.

* But when i add the "asn_check_constraints" it shows as below error on the arm device:
  MessageFrame constraint validation failed: Millisecond: value too large (Millisecond.c:26)

Can you provide a minimal, reproducible example (together with asn1, makefiles, etc...)

from asn1c.

Thanks a lot @velichkov. please find below details:

• Yes, i am using the vlm_master branch of the mouse07410's fork (sorry might not be using latest commit):
  https://github.com/mouse07410/asn1c/blob/vlm_master/INSTALL.md

• please find attached zip-file which contains the asn.1 and makefiles (i am using the Makefile of the vlm_master/examples/sample.source.J2735/Makefile and modifying the .asn1 file with the test_rectangle.asn1)
  onlinegit.zip

@velichkov apologies for following up, would it be possible to share any valuable feedback ?

from asn1c.

@velichkov tried with the latest master repo of the below git-repo and still it gives the same issue:

https://github.com/mouse07410/asn1c

from asn1c.

@yadav9997 If you want to encode/decode a large integer value, both this repo and https://github.com/mouse07410/asn1c will work well. However, if you're trying to use constraints that large, it will not work, sorry. Supporting that would require implementing constraints of type INTEGER_t (as opposed to int64_t or such) - the code to do that is not there.
