RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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

--- Additional comment from Tomas Halman on 2022-01-11 18:07:53 UTC ---

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

It is not fixed upstream yet.

--- Additional comment from Tomas Halman on 2022-01-20 10:23:42 UTC ---

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
