SARG ChangeLog

May-21-2012 Version 2.3.3-pre1
		- Don't abort the report generation due to an error in a squidGuard error (wrapped over log lines).
		- Support for gd, ldap and iconv can be disabled during configuration.
		- Suppress the blank line breaking the header of the e-mail report.
		- Add many debug messages to help understanding why some parts of the report are not produced. Considering all the options and various conditions that are involved in the creation of a report, that help is welcome.
		- Fix the report generation if users_sites is disabled.
		- Avoid a possible name clash among the temporary files if a user happen to have the same name as one of the files sarg generates.
		- Fix various links and reports when some options are disabled.
		- Accept regular expressions in the hostalias file.
		- URL in SquidGuard logs sometime don't have a scheme. This is now handled properly.
		- Exclude hosts based on the IPv4 address even if a port number is suffixed after the IP address. (thanks to Mark Easter for reporting the bug).
		- IP addresses can be resolved to host names using an external program.

Dec-07-2011 Version 2.3.2
		- Add support for sorttable.js (http://www.kryogenix.org/code/browser/sorttable/) to dynamically sort some tables (thanks to Éric).
		- Add the two command line options --lastlog and --keeplogs to set the number of reports to keep or to keep all the reports respectively (thanks to Emmanuel Lacour for the suggestion).
		- Report the user ID in the e-mail report.
		- Add an option to sort the top sites by time.
		- Delete unused files from the directory containing the user report (thanks to alf-man).
		- Add the index_fields option to hide the directory size column in the index sorted by date.
		- Split the input log file in several files each containing one day worth of data (thanks to Mauricio Silveira).
		- Take the date_format into account when converting a log file.
		- Accept IPv6 addresses in the realtime report.
		- Don't fail for an empty report directory when building the index.
		- Fix a read error when parsing the time of a common log format (thanks to Richard P Scott).
		- Use anonymous file and directory names in the report to hide the identity of the user whose report is displayed and shorten the total path length.
		- More robust calls to external sort commands (guard against buffer overflows and use tab as column separator).
		- Replace host names by aliases and group identicaly aliased host names.
		- IPv6 is accepted in the hosts exclusion list.
		- Discriminate between users whose name produce the same mangled temporary file name.
		- Write a note about the number of entries ignored in the reports (thanks to Iain Lopata).
		- Command line option -z output some messages to explain why the reports are not generated due to the configuration.
		- The Sites & Users report page links to the user's page if the user is listed in the Top Users page.

Sep-18-2010 Version 2.3.1
		- Remove the distinct printf for the alpha architecture as it doesn't work anymore and is not necessary anyway.
		- Don't abort if "onload" or "script" is found in the user agent string.
		- Take the configured locale path into account when installing sarg.
		- Fix the realtime and e-mail reports.
		- Allow for the translation of the sort criterion on the report pages.
		- The mail_utility command isn't quoted any more so it is possible to add some command line arguments.
		- Fix a wrongly reported error if the two "hours" and "weekdays" options are enabled in sarg.conf (thanks to guyizsolt).
		- Add a link on the denied page to link the page to the corresponding user.
		- Fix a problem with the progress indicator when reading from a compressed log file.
		- Report an error if the output directory is a subdirectory of the temporary directory.
		- Use a more robust protection against an attack using javascript in the useragent string.
		- Prevent a segfault if the parameter passed to command line option -d is invalid (thanks to ItalianPenguin).
		- Check for the return code of the tail command to generate the realtime report.
		- Escape the invalid characters in the LDAP search string instead of truncating it at the first invalid character (thanks to mouchar for reporting the problem and testing the fix).

Jun-21-2010 Version 2.3
		- LDAP usertab added. 
		  Now you can have your users in a LDAP Server.
		  Use these tags in sarg.conf: LDAPHost, LDAPPort, LDAPBindDN, LDAPBindPW,
		                               LDAPBaseSearch, LDAPFilterSearch
		- Parse the string flags from sarg.conf once during the reading of sarg.conf instead of manipulating and duplicating the tests of the strings where they are used.
		- Useragent report limited to requested date range.
		- Link to external css file instead of including it verbatim in each HTML file (thanks to Maxim Britov).
		- Enable gettext configuration for autotools.
		- Use gettext translations instead of the custom languages files.
		- Keep the user name unchanged in the report (suppress the replacement of some characters by underscores).
		- Try to resolve a user's IP address only once and store the result. It can speed up the processing a lot.
		- Resolve IPv6 addresses (to be tested).
		- Don't limit the maximum length of a URL (the only limit is that a single line of text from the log file must fit in memory).
		- The creation of the datafile is working again.
		- Use a template to build the .htaccess file of each report.
		- Accept spaces in the replacement label of the usertab file (thanks to Alex Sav).
		- Change the version number of the release candidate to conform to the numbering of the translationproject.org.
		- Store the period internaly and get rid of the sarg-period file.
		- Display the period using the locale's month name in the HTML files.
		- Check the correct writing of the HTML files (thanks to Markus Elfring).
		- Use the word "Redirector" instead of mentioning explicitly squidGuard in the reports as at least Rejik is compatible with sarg (thanks to Maxim Britov).
		- The date range passed as argument is not restricted to the actual range covered by the log files any more.
		- Fix the exclusion of status codes to exclude more than one code.
		- Accept date ranges for -d command line option as day-n, week-n and month-n where n is the number of backward days, weeks and months to report.
		- Strengthen the making of the report file name to drastically limit the characters from the user ID that can appear in the file name. The presence of an unescaped backquote in the user ID would execute the rest of the name as a shell command (fixes bug #2997707 reported by anonymous).
		- Purge the content of sarg-general to free a lot of disk space.
		- Use parameteric dimensions in the graph creation instead of hard coded constants.
		- Remove the temporary file and sorting in graph creation.
		- Add the redirector_log option in sarg.conf to read a log file created by squidGuard or Rejik (thanks to Maxim Britov for pointing out this missing option).
		- Allow up to 64 redirector log files to be passed through the command line option -L and the sarg.conf option redirector_log.
		- Configuration option squidguard_log_format renamed into redirector_log_format for equity with the various redirectors that can be used with sarg.
		- Read a compressed log file through a pipe.
		- The graph was wrong. The bars were not reaching the correct height with respect to the Y axis.
		- Use a computed logarithmic scale for the Y axis when plotting bytes data instead of a fixed scale.
		- Show the time when plotting the elapsed time.
		- Fix the reporting of only one user with command line option -u.
		- Output both date/time textual and graphical reports.
		- Sarg log file now stores the date in the format dd/mm/yyyy and doesn't change it depending on the current date representation selected in sarg.conf. It will break existing sarg log files.
		- Intermediary log files store the date as dd/mm/yyyy irrespective of the current date representation in sarg.conf.
		- Fix a regression to accept any directory name length in the index.
		- Change the CSS template file and cleanup of the hardcoded styles (thanks to Maxim Britov).
		- Accept unlimited line length when converting or splitting the log file.
		- Use long options on the command line.
		- Sarg can output the internal css inlined in the reports. It replaces the css.tpl distributed with the sources.
		- Command line option -l is optional. The input log files may be named on the command line without prefixing them with -l. It allows the use of wildcards in the command line.
		- Accept unlimited URL length in the redirector log (thanks to Joseph L Casale).
		- Replace redirector_ignore_date by redirector_filter_out_date that behave as the name implies.
		- Replace dansguardian_ignore_date by dansguardian_filter_out_date that behave as the name implies.

Feb-10-2010 Version 2.2.7.1
		- Fixed compilation error reported by some compilers due to an sizeof in a fprintf (thanks to Maxim Britov and Renato Botelho).
		- The path to the font used to create the graphs can be set in sarg.conf.
		- The installation of our fonts can be disabled with --disable-fontdir.

Feb-05-2010 Version 2.2.7
		- Extra compile and run time protection (FORTIFY_SOURCE) fixed in configure.
		- Use tabulations as columns separator in intermediary files to avoid problems when a field of the log contains a space.
		- Input log file type detection partly rewritten to clearly distinguish which type is processed where.
		- Read the input log file from standard input if log file name is -.
		- Use string pointers in getword instead of copying the strings over and over.
		- Use LC_TIME to format some dates and times in the report according to the selected locale.
		- Sarg.conf can list up to 255 access.log files.
		- Downloaded files suffixes are matched against a sorted list and use a dichotomic search.
		- Added getword_atoll to read a number directly from a file without an intermediary string storage.
		- Use boolean to enable the options instead of string compares.
		- Accept an absolute path for the language file in sarg.conf.
		- Experimental: Can show the backtrace of the program when a getword loop is detected to help in locating the origin of the error.
		- Protect the creation of the index against invalid directories.
		- Only copy the files (not the subdirs) when creating the directory with the images to include in the reports.
		- Directories deleted without using the rm system command.
		- Index created using an internal sort algorithm instead of a system call.
		- Fixed Debian bug #408577 (changed exclude_hosts to exclude subdomains and IPv4 subnets).
		- Replace --enable-htmldir by --enable-sargphp to avoid confusion on the name (thanks to Peter Nixon).
		- Installation of sarg-php can be disabled with --disable-sargphp.
		- Fixed empty entries in squidGuard log when the URL doesn't start with protocol://.
		- Fixed regressions in creation and reading of a sarg parsed log (thanks to Joao Alves).
		- Does not report URLs consisting of only a host name ending with .com as a downloaded file.
		- Mangle the $ and @ signs in user ID to make the resulting file name valid in shell commands.
		- Fixed a regression in the default value of --enable-sargphp.
		- Increase the maximum size of a line read from access.log and detect longer lines that were silently splitted in previous versions.

		- Remove warnings if libgd is not available.
		- The date stored in sarg-date is now stored in a more machine readable form (thanks to rcastanheira for pointing this out).
		- The date read from sarg-date was not properly parsed and would produce a wrongly sorted index across a year change (thanks to rcastanheira for pointing this out).
		- my_mkdir changed to avoid the use of getword, be simpler and, maybe, work reliably on windows.

Mar-03-2008	Version 2.2.5
		- new fix to the script insertion vulnerability via user-agent
		  report. javascript can still be executed via e.g. the "<BODY onload=function();>" scheme
		     Thanks to Alin Rad Pop, Security Specialist, Secunia, Denmark

Mar-02-2008	version 2.2.4
		- security issues can be exploited to execute arbitrary code when sarg
		  is used with malicious input files.
		  The vulnerability within the processing of the useragent.log is rather
		  critical, as this can be exploited by passing a long user agent string
	          when browsing via a squid proxy. the manipulated GET request in the
	          access log would not be accepted by squid, so that file has to be specially crafted.
		     Thank you to L4teral l4teral@gmail.com

		- French language fixed.
		    Thanks to Nicod <smlpnicod@orange.fr>
		- Fixed: Segfault in x86_64

		- date period invalid in download reports
		- wrong results when userid contain '%20' character
		- previous reports info wrong in index.html

Dec/23/2006	Version 2.2.3
		- gd graph font change from FreeSans.ttf to DejaVuSans.ttf
		- minor fixes when only denied records in access.log file.
		- ulimit tag changed. If you run sarg with a low privilege user, 
		  set to 'none' to disable ulimit.
		     Thanks to Jorge Morgado <jorge@morgado.ch>
		- Russian_UTF-8 language fixed by Igor Ageikin <iageikin@lipen.elektra.ru>
		- realtime_unauthenticated_records tag changed to show by default.
		- chmod 755 in sarg-php due to errors in rpmbuild.
		     Thanks to Davide Madrisan <davide.madrisan@gmail.com>
		- when the keyword "anonymous" is used in squidGuard.conf, Sarg does
		  not find the log-files anymore. 
		     Thanks to Daniel Vogel <daniel_vogel@t-online.de>
		- after reading the squidGuard configuration, the data read from the
		  usertab file was corrupted. 
		     Thanks to Daniel Vogel <daniel_vogel@t-online.de>
		- millisec values showed as bytes. Thanks to Carlos <ke09@terra.com.br> 
		- with squidGuard, you can log groups in only one log file.
		  We must parse each log files only one time. 
		     Thanks to Christophe BADINA <christophe.badina@ch-moulins-yzeure.fr>
		- error message(removetmp) Cannot open /tmp/sarg_tmp/../general
		  when sending report by email. Thanks to Peter Volkov <pva@gentoo.org>
		- incorrect off_t size in printf. In FreeBSD off_t is 64bit long long,
		  but sarg always use %d to display off_t in log processing. This cause garbage
		  while reading log files on a freebsd, and possible crash.
		     Thanks to Alex Samorukov <samm@os2.kiev.ua>
		- squid24 on/off tag added in sarg.conf to implement compatibility if using
		  squid <= 2.4 and using squid common logs.

		- SARG support Japanese wordset but not support charset.
		     submitted by anonymous at sourceforge.net  Many thanks.
		- support for utf-8 character set added by Peter Warasin
		     <peter-endian@users.sourceforge.net>. Many thanks.
	        - if all the data is at the hour each day, totaliza_day() treats it all as being 
		  on the last day. This is observed for users which only download via a cron job
		  at the same time each day. Now the date and time will be
		  checked to see if changed. 
		     Thanks to Ian Dall <iandall@users.sourceforge.net>
		- greport_day() doesn't add the volume for the first hour of each day to the total.
		     Thanks to Ian Dall <iandall@users.sourceforge.net>
		- Russian_koi8 and Russian_windows1251 languages updated by

			  doesn't support '?' symbol in links (all of them interpret this like 
			  parameter to cgi script);

			  reducing false checks in 'if ...' strings.
		   . Fixes segfault, produced by improper use of strncpy functions, look - strncpy 
		     doesn't copy leading '\0' symbol!
		   . Just localization support for repday report.
		   . Support usertab IP->USERNAME change in siteuser report.
		   . Just proper Russian koi8 localization.
