Added ^W patch (from thaquis). + Fixed bug in xdprintf. Added command line options for the "t" and + "m" commands. + SunOS 5 changes: Support for showing individual threads. Redid + allocation of prpsinfo structures. Added a pidthr hash that uses + both pid and thread id for a key. Changed format_process_header + and format_next_process to use a table-driven method for generating + the columns. Status files from /proc (psinfo and lpsinfo) are now + cached to avoid repeatedly reopening them. Column showing number of + LWPs is now called "NLWP" and column showing lwpid is "LWP". + FreeBSD changes: Runtime check to ensure binary is running on + the same machine type it was compiled for. Lots of cleanup and + changed nearly everything to use sysctl rather than kvm, and + inability to open kvm is no longer fatal. Improved thread reporting: + disabled for 7.x and lower. Added lwpid hash for proper tracking + of threads. Changed format_process_header and format_next_process + to use a table-driven method for generating the columns. + Dec Alpha: configure uses compile-time options to properly trap + and handle exceptions from the Alpha FPU (from Brian Maly). + +Tue Feb 26 2008 - wnl (3.7) + Prepare for version 3.7 release. + +Fri Feb 1 2008 - wnl (3.7beta4) + Using the $ notation in printf formats for freebsd apparently was + causing problems on 64-bit systems. All such usage has been + removed and the process line is formatted piecemeal. + +Thu Dec 27 2007 - wnl (3.7beta3) + Improved function comments in display.c for message_error functions. + Changed some of the error messages in top.c to be more succint. + +Fri Dec 7 2007 - wnl (3.7beta3) + Changes to freebsd port: moved some functions up front to + eliminate forward references. Use sysctl to get all vm stats + information, as some of this isn't updated in the struct + vmmeter under FreeBSD 7.0. Added routines to support large-scale + sysctl access. + +Wed Nov 28 2007 - wnl (3.7beta3) + Changes to documentation: FAQ, README, man page. + +Tue Nov 27 2007 - wnl (3.7beta3) + For freebsd, added page faults, pageins, pageouts, and pages + freed to the kernel display line. These numbers reflect the + values presented in vmstat. For sunos5, added page faults, + pageins and pageouts to the kernel display line. + +Fri Nov 2 2007 - wnl (3.7beta3) + Added copyright notices to the top of every source and include file. + Added copyright information to the man page. + Removed a few outdated things from the manifest. + Minor changes to sigconv.awk. + +Sat Oct 27 2007 - wnl (3.7beta3) + Added check for sys_signame at configure time and if it is + present then it is used in commands.c to translate signal names + in to numbers. + Added alternate snprintf and vsnprintf functions from apache (in + ap_snprintf.c). Added configure magic to define and compile them in + where needed. Added check to configure for variadic macros. + Preprocessor defintion of dprintf (in utils.h) now depends on + support for variadic macros. Cleaned up m_linux code. + +Wed Oct 3 2007 - wnl (3.7beta3) + Lots of changes, thanks to Mark Wong. Most changes were to + clean the code up so that it would compile cleanly with -Wall + (all warnings). Changed function names in screen.c so that + they all start with "screen_". Isolated all interaction with + termcap to screen.c by adding a real function for cursor + addressing (in the past it was just a macro). Only screen.c + now needs to worry about defining templates for the termcap + functions. Added configure and preprocessor magic to ensure + that all the termcap functions used in the code are defined + with templates. Changed names of some other functions and + global variables to avoid name conflicts with functions in + curses and other well established libraries. Changed dprintf + macro to use variadic arguments so that the preprocessor can + gobble up the entire call when compiling without debugging + (this will have to be made more portable). All include files + are surrounded by #ifndef statements to accomodate multiple + inclusions. Platform module is now compiled with + -fno-strict-aliasing as some of the modules do type punning + that can confuse the optimizer. + +Wed Sep 26 2007 - wnl (3.7beta3) + For freebsd, priority is no longer normalized by PZERO. This + contradicts the behavior used by ps when it displays priority. + But normalizing by PZERO has become a bit of an anachronism + and it actually obscures the meaning of the priority without + adding any real value. + +Wed Sep 19 2007 - wnl (3.7beta3) + Many changes to improve the display of threads. Changed + process summary line to use the word "threads" when showing + individual threads. Added the system command to toggle the + display of system processes. Fixed bug in hash.c remove_pos. + For freebsd: count threads correctly when they are being + displayed, nice column is more closely in line with ps + (nothing fancy for real time processes), add two more process + states that didn't exist in older releases of freebsd (wait + and lock). + For linux: Threads done right. Now track individual threads + of multi-threaded processes separately so that we always know + their %cpu. Switch to format_process_header so that we can + change the column headings and remove the THR column when + displaying individual threads. Switched process (and thread) + tracking over to use generic hash table functions included + with the new version of top. Process states and total now + include threads when they are being shown. Added "SHR" column + to show the amount of shared memory per process. Improved + calculation of elapsed time and percent cpu to avoid + overflows. Remove weighted cpu calculations entirely as it is + an anachronism. + For Solaris: Moved check for libelf to accomodate older systems. + +Sun Sep 9 2007 - wnl (3.7beta2) + Documentation changes. Fixes to sunos5 port. Added display of + thread count and selection by command name to linux port. Removed + the use of inline functions from hash.c as that doesn't appear to + be very portable. + +Wed Sep 5 2007 - wnl (3.7beta1) + Fixed freebsd and linux configuration bugs. Added configuration + options for tweaking program defaults. Rewrote top level code + (top.c) from scratch, including command handling so that adding + new commands is much easier. Changed message-line handling to + ensure that the message is displayed for at least 5 seconds + regardless of the update frequency. Added a "miniupdate" that + occurs one second after the initial screen on systems that don't + already delay the first screen. The mini-update shows cpu state + percentages. Added ability to select output by command name on + some systems. Fixed color toggling via the "C" command. Added + long options via getopt_long to complement the existing single + character options. Added the freebsd "m" command to chose + alternate display modes. On freebsd this gives a process i/o + display. Added the freebsd "H" command to select the display of + individual threads. Added "-a" option ("all") to set number of + displays and number of processes to infinity (equivalent to + "-d all all"). Added dual architecture compilation for Solaris + to generate both a 32-bit and a 64-bit binary. This is on by + default when compiling on a 64-bit system and can be explicitly + set via "configure --enable-dualarch". Added uniform hashing + functions that use bucket hash for uint, pid, and string. Changed + username.c and the sunos and freebsd modules to use these functions. + Added the "kernel" information line to the display to show + statistics on what the kernel is doing (context switches, forks, + traps, etc.). This requires explicit support by the platform + module, currently only freebsd, linux, and sunos. + +Wed Apr 18 2007 - wnl (3.6.1) + Fixed a few bugs in sigconv.awk that were causing incorrect + results on FreeBSD. Changed configure.ac to fix a few linux + problems: signal include file and /proc/1/stat. + +Fri Apr 13 2007 - wnl (3.6.1) + Removed the use of VPATH for compiling the system module and used + an explicit dependency in the Makefile instead. VPATH is now set + to just srcdir to ensure that top will compile correctly when + configured from a different directory. On systems without VPATH + support, top will still configure and compile, but only + from within the source directory. This fixes bug 1699526. + +Fri Feb 2 2007 - wnl (3.6.1) + Revised the way that configure figures out owner, group, and mode. + For systems that don't use the kernel, it tries to match install + settings to allow access to stuff in /proc. More importantly, if + mode is 755 then neither owner nor group are set. This fixes bug + 1631136. Added patch from haanjdj@xs4all.nl to fix an occasional + core dump in m_decosf1.c. This checks return code from task_threads. + Made sure all get_system_info functions are declared void. Fixed + string termination bug. Cleaned up documetation for sunos5. + +Tue Aug 8 2006 - wnl (3.6.1) + For Solaris, changed the tag "swap" to "total swap" to clarify + what is beign displayed. Note that the calculations are still the + same: the display is just showing total rather than total - free. + +Thu Apr 27 2006 - wnl (3.6) + Added patches for linux-style sort shortcuts and for Unixware + support in configure (patch 1474427). Fixed sunos5 to do slow start + and to ensure cpucount is set (patch 1477386). Added pagination + routines to display.c and modified show_help to use it, since the + help screen is now longer than 24 lines. Applied patch for unixware + support that adds check for mas library (patch #1474423). Solaris + cpu percent now reflects a percentage of the entire server, rather + than a single cpu (bug 1478138). + +Mon Mar 27 2006 - wnl (3.6) + The production release of version 3.6. Fixed a minor scaling + bug in the decosf1 module. Support for MacOS X is officially + withdrawn although the macosx module is still part of the + distribution. Hopefully this is a temporary situation. + Documentation updated. + + +Wed Feb 15 2006 - wnl (3.6beta5) + Minor changes to eliminate warnings from the Sun Studio compiler. + These were mostly sloppy argument declarations. I also added + message.h to provide an interface file for just the message + related functions of display.c. + +Mon Dec 26 2005 - wnl (3.6beta4) + Added new netbsd module, courtesy of Simon Burge. + Fixed a few bugs in SVR4 module and added its use to + configure.ac, thanks to Sanchet Dighe. Also ensured that the + novpath Makefile was in the distribution. + Fixed portability problem in display.c + + +Mon Oct 24 2005 - wnl (3.6beta3) + Set up a color tagging mechanism in color.c to allow for the + dynamic creation of tag names to contol color highlighting. + These names are partially derived from the tags used to label + memory and swap information on the screen, thus are driven by + the machine module itself. Added -T option to list color + highlighting information. Help screen now includes the actual + list of sort order names. Incorporated some minor fixes to + the main code from the Freebsd source tree. Fixed bug #1324582. + Freebsd 5: removed WCPU column and added THR column. Display + for freebsd 4 and earlier unchanged since they don't track + threads in the kernel. Added LICENSE file to distribution. + +Wed Oct 12 2005 - wnl (3.6beta2) + Major overhaul to display.c. All lines of the display are + directly tracked and controlled via display_write and its + companion display_fmt. Added support for complete control + of ANSI color on the screen: this will be used in the future + to allow for full use of color everywhere on the screen. + Signal handling code now uses sigaction on all systems that + support it. Restored the freebsd module and did away with + freebsd4, and upgraded freebsd module to support 5.x. + Fix bug #1306099 (wio(wait) timer ignored on OSF1). + +Fri Sep 23 2005 - wnl (3.6beta1) + Fixed bugs #1266341 (compilation errors with gcc 4.x), + #1156464 (cpu% field for sunos), #1156243 (compilation + errors on AIX). Applied patches #1217855 (Solaris 10 + xarch flag). Overhaul of sunos5 module, making code more + efficient and easier to follow. Got rid of need for MEMTYPE + type in utils.h. Changed all memory statistics data in the + module specification from an int to a long to better support + 64-bit systems with lots of memory. Moved all unused modules + out of the distribution (I will add them back in as needed). + Moved freebsd module to freebsd4 as it won't work with 5.x + (a new module will be necessary). Added support to configure + for makes that don't understand VPATH. Updated documentation: + man page, FAQ, README, INSTALL. + +Mon Jan 24 2005 - wnl (3.6alpha10) + Updated aix43 module with ANSI function declarations and fixed + declaration of get_system_info. Configure now uses irixsgi + module for irix6* systems. Updates to the following modules: + irixsgi, sunos5. Fixed null pointer bug in color.c. Removed + some useless code and definitions in display.c + + +Sun Nov 28 2004 - wnl (3.6alpha9) + Replace AIX 5 module with alternate (bug 1056565). + Fixed vulnerability in use of snprintf. + +Fri Oct 22 2004 - wnl (3.6alpha8) + Support for linux 2.6, added more stuff to memory and swap lines. + Updated linuxthr module, which is only useful on 2.4 and earlier. + Added some color support back in (feature request 930588), but + still need to add it back to the per-process display. Added + OSF 5 support (untested). + Fixed bug 1017951 (invalid process count argument not caught) + +Tue Apr 20 2004 - wnl (3.6alpha7) + Added 64 bit support for AIX. + +Thu Apr 15 2004 - wnl (3.6alpha6) + Included fixes for decosf1 pid size and updated module. Also + added osf1 to list of recognized operating systems in configure.ac. + +Tue Mar 30 2004 - wnl (3.6alpha5) + Minor bug fixes and some code rearrangement. Changes to install + rule. Added several more platforms including: aix 4.2 thru 5, + MacOS 10, Dec OSF, HPUX 7 thru 11. Fixed the core dumping bug + in linux. Code cleanup, including sigdesc.h (by changing + sigconv.awk). Startup error messages are displayed on the + first screen rather than beforehand (no more pause). Cleaned + up interrupt handling to avoid a race condition. Eliminated + top.local.h. REMOVED Configure!!! + +Mon Mar 22 2004 - wnl (3.6alpha1) + Now using gnu autoconf. Eliminated the need for CFLAGS and LIBS + tags in the module source files. Autoconf tries to figure all + that out now. Machine module interface now uses flags to determine + if module supports sorting, selective display of idle processes, + viewing full commands. Added display of uptime for modules that + support it. Added display of full command lines for modules that + support it. 3.5 modules must be changed a bit to work for 3.6: + ORDER is no longer defined, and the module must fill in the + appropriate fields in struct statics to get the extra features. + Added a extenstion interface to allow for putting extra stuff + on the screen -- this is still half baked and not documented. + +Mon Feb 23 2004 - wnl (3.5) + Turned rc1 in to version 3.5. Only changes were to the FAQ. + +Mon Feb 2 2004 - wnl (3.5rc1) + Changed format_k (utils.c) to use MEMTYPE for its parameter. + On most systems this is a long, but if the module defines + USE_SIZE_T, this is set to be a size_t. The sunos5 module + now defines it, so that it will work correctly on 64-bit + machines. New "linuxthr" module for rolling up processes + that are really threads. Configure autodetects when running + on a 64-bit Solaris machine. + +Tue Dec 16 2003 - wnl (3.5beta13) + Improved linux module. For Solaris, changed "THR" column + heading to "LWP" since that's what they really are. + Thu Mar 30 2000 - wnl (3.5beta12) Updated modules: m_aix41.c, m_aix43.c, m_mtxinu.c, m_sco5.c, and m_ultrix4.c. |
