+
+
      
+
    • 1.727 https website and CGI on the way!
      • 
+
+
+
    • Security: Thanks to free and easy letsencrypt, 
+Imapsync website is available in https: 
+https://imapsync.lamiral.info/
+
      • 
+
+
    • Enhancement: Added option --delete1emptyfolders. It deletes empty folders on host1, INBOX excepted. 
+Useful with --delete since what remains on host1 is only what failed to be synced.
      • 
+
+
    • Enhancement: Imapsync can be used as a CGI program. Still experimental. The web UI interface has to be written.
      • 
+
    • Enhancement: XOAUTH2 authentication works with json files without extra tool openssl. Old pk12 files are still supported (still with openssl).
      • 
+
    • Enhancement: Memory usage passed from 5x to 2x of the biggest message size. 
+Some users do send 700MB messages, imapsync needed 3.5 GB of RAM, now it crunches only 1.4 GB, 
+a more common RAM value available on small hosts.
      • 
+
+
    • Enhancement: Added option --inet4 to force ipv4 in ssl and tls modes. 
+Useful with Gmail and Office365 when ipv6 is disable on the imapsync host but not ipv6 resolution.
      • 
+
+
    • Enhancement: Reconnect to imap servers with a Ctrl-c. Exit with two Ctrl-c within one second or one Ctrl-\
      • 
+
    • Enhancement: Copy is not done when one --pipemess command ends with an empty message generated.
      • 
+
    • Enhancement: STDERR of --pipemess commands are reported on STDOUT and in the logfile (they were ignored before).
      • 
+
    • Enhancement: 
      • 
+
+
    • Dependency: Added Perl module dependency of Readonly to transform hard coded magic numbers into names. Mandatory module.
      • 
+
    • Dependency: Added Perl module dependency of Test::MockObject for some tests. Only a "require" for now.
      • 
+
+
+
    • Security: In CGI mode, remove all content in the unsafe "eval"uated options 
+                     (--regextrans2 --regexflag --regexmess --skipmess --pipemess --delete2foldersonly --delete2foldersbutnot). 
+                     Consider these options not available in CGI mode.
      • 
+
+
+
    • Bug fix: Fixed -1 wrong output in statistics for big accounts (%d => %s) in printf.
      • 
+
    • Bug fix: Uncommented call to $test_builder->reset(  ) Don't know why it was commented but it was bad for knowing tests go wrong.
      • 
+
    • Bug fix: Check connected state in sub create_folder(). Avoid multiple useless failures.
      • 
+
+
+
    • Refactoring: Wrote Perl package Imapsync::Getopt::Long to handle CGI requests like command line options. 
+Started as a copy of Luke Ross Getopt::Long::CGI
      • 
+
    • Refactoring: Perlcritic cleanup 627 violations of CodeLayout::ProhibitTrailingWhitespace.
      • 
+
    • Refactoring: Perlcritic cleanup 60 Double-sigil dereferences.
      • 
+
    • Refactoring: Perlcritic cleanup 458 ValuesAndExpressions::ProhibitInterpolationOfLiterals. "Useless interpolation of literal string"
      • 
+
    • Refactoring: Perlcritic cleanup 420 CodeLayout::ProhibitParensWithBuiltins. "Builtin function called with parentheses". (Severity: 1).
      • 
+
    • Refactoring: Perlcritic cleanup, various small advices.
      • 
+
+
    • Refactoring: Replaced print by myprint, printf by myprintf, sprinf by mysprintf. 
+                        Will ease --quiet mode and general output handling.

-Hello $F->{Nom},
-
-First of all, I'm sorry for the delay in getting back to you.
-
-Last imapsync release is available from the page
-http://imapsync.lamiral.info/paypal_return.shtml
-
-You'll find in the attachment the invoice of imapsync 
-$F->{object_type} you bought and paid (dd/mm/yyyy $F->{Date}).
-The invoice file is named facture_imapsync-${invoice}.pdf
-This invoice is in PDF format, ready to be print.
-
-Should you need a hardcopy of this invoice, 
-I'll send it to you upon request by regular mail.
-
-As the law requires, this numeric invoice PDF file 
-is signed with my private gpg key.
-
-The resulting gpg signature is in the file named 
-facture_imapsync-${invoice}.pdf.asc
-you will also find in the attachment.
-
-You can check I (Gilles LAMIRAL) really did generate 
-this invoice with the following command line:
-
-  gpg --verify facture_imapsync-${invoice}.pdf.asc facture_imapsync-${invoice}.pdf
-
-or any other gpg graphical tool.
-
-Once more, thank you for buying and using imapsync $F->{object_type}.
-
-Any feedback is welcome.

+This is a multiline comment.

+* Call parameters stay the same.
+* Now always "return( $string, $error )". Descriptions below.
+OK * Still    capture STDOUT via "1> $output_tmpfile" to finish in $string and "return( $string, $error )"
+OK * Now also capture STDERR via "2> $error_tmpfile"  to finish in $error  and "return( $string, $error )"
+OK * in case of CHILD_ERROR, return( undef, $error ) 
+  and print $error, with folder/UID/maybeSubject context,
+  on console and at the end with the final error listing. Count this as a sync error.
+* in case of good command, take final $string as is, unless void. In case $error with value then print it.
+* in case of good command and final $string empty, consider it like CHILD_ERROR =>
+  return( undef, $error ) and print $error, with folder/UID/maybeSubject context,
