Description Tomas Halman 2022-02-02 12:33:32 UTC

+++ This bug was initially created as a clone of Bug #2017285 +++

Description of problem:

An error raised and caught during an iteration appears to interrupt the iteration. 
In the example below the intent is to convert all "strings" into "numbers" when they can be and to ignore all other values.


Version-Release number of selected component (if applicable):
jq-1.6-10.fc34.x86_64

How reproducible:
every time

Steps to Reproduce:
1. `jq '.[]| tonumber? ' <<< '["1", "2", "a", "3"]'`

Actual results:
```
1
2
```


Expected results:

```
1
2
3
```


Additional info:
Problem seems to have appeared with 1.6-10

This issue has been introduced in commit https://github.com/stedolan/jq/commit/cf4b48c7ba30cb30e116b523cff036ea481459f

It is not fixed upstream yet.

In fact `jq` does not stop iterrating, it just stops converting and printing strings

    jq '.[]| tonumber? ' <<< '["1", "a", "2", 3]'

will print 1 and 3 because 3 is not converted from string.

Here is the PR to discuss and find the fix: https://github.com/stedolan/jq/pull/2400

The issue can be also avoided by providing `--disable-decnum` configure option
