Subject [jira] Commented: (STDCXX-2) [MSVC] std::num_put bad formatting of 0.0 with precision and showpoint
Date Thu, 14 Feb 2008 23:57:11 GMT

    [ https://issues.apache.org/jira/browse/STDCXX-2?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12569138#action_12569138
] 

Martin Sebor commented on STDCXX-2:
-----------------------------------

Btw., changing the file suffix from {{.diff}} to {{.diff2}} prevents some browsers from recognizing
the file type. If Jira requires the names of attachments to be unique, or if we want to make
them unique to preserve the chronological order in which they were attached, I suggest appending
the number to the base name of the file. I.e., go with {{file.diff}},  {{file-2.diff}}, {{file-3.diff}},
etc.
