2021-09-05Add a Process_printPercentage helper routineHisham Muhammad
Replace several open-coded variants of percentage formatting. This function has been ported from Hishams old 'next' branch.

2021-08-13PCP: support for 'dynamic columns' added at runtimeSohaib Mohamed
Implements support for arbitrary Performance Co-Pilot metrics with per-process instance domains to form new htop columns. The column-to-metric mappings are setup using configuration files which will be documented via man pages as part of a follow-up commit. We provide an initial set of column configurations so as to provide new capabilities to pcp-htop: including configs for containers, open fd counts, scheduler run queue time, tcp/udp bytes/calls sent/recv, delay acct, virtual machine guests, detailed virtual memory, swap. Note there is a change to the configuration file path resolution algorithm introduced for 'dynamic meters'. First, look in any custom PCP_HTOP_DIR location. Then iterate, in priority order, users home directory, then local sysadmins files in /etc/pcp/htop, then readonly configuration files below /usr/share/pcp/htop. This final location becomes the preferred place for our own shipped meter and column files. The Settings file (htoprc) writing code is updated to not using the numeric identifier for dynamic columns. The same strategy used for dynamic meters is used here where we write Dynamic(name) so the name can be setup once more at start. Regular (static) columns writing to htoprc - i.e. numerically indexed - is unchanged.

Shared libraries can be replaced by an upgrade, highlight processes using deleted shared libraries. Link with highlightDeletedExe setting, enabled by default. Currently only checked on Linux.

2021-05-23Add ELAPSED process columnChristian Göttsche
Add process columns showing the elapsed time since the process was started. Similar to STARTTIME, but shows the time passed since the process start instead of the fixed start time of the process. Closes https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=782636

2021-04-26Rework process field print functionsChristian Göttsche
Make functions formatting data for a process field column less error prone, unify interfaces and improve some internals. * Process_printBytes - rename from Process_humanNumber - take number in bytes, not kilobytes - handle petabytes - increase buffer to avoid crashes when the passed value is ~ ULLONG_MAX * Process_printKBytes - add wrapper for Process_printBytes taking kilobytes keeping -1 as special value * Process_printCount - rename from Process_colorNumber * Process_printTime - add coloring parameter as other print functions - improve coloring and formatting for larger times * Process_printRate - rename from Process_outputRate - use local buffer instead of passed one; this function prints to the RichString after all
2021-04-14Rework TTY columnChristian Göttsche
* Rename internal identifier from TTY_NR to just TTY * Unify column header on platforms * Use devname(3) on BSD derivate to show the actual terminal, simplifies current FreeBSD implementation. * Use 'unsigned long int' as id type, to fit dev_t on Linux. Only on Solaris the terminal path is not yet resolved.
2021-04-05Request the realtime and monotonic clock times once per sampleNathan Scott
Refactor the sample time code to make one call to gettimeofday (aka the realtime clock in clock_gettime, when available) and one to the monotonic clock. Stores each in more appropriately named ProcessList fields for ready access when needed. Every platform gets the opportunity to provide their own clock code, and the existing Mac OS X specific code is moved below darwin instead of in Compat. A couple of leftover time(2) calls are converted to use these ProcessList fields as well, instead of yet again sampling the system clock. Related to https://github.com/htop-dev/htop/pull/574

2021-01-30Linux: overhaul io process fieldsChristian Göttsche
- avoid UBSAN conversions - print N/A on no data (i.e. as unprivileged user) - fix rate calculation to show bytes (instead of a thousandth) - print bytes as human number (i.e. 8MB) instead of 8388608 - stabilize sorting by adjusting NAN values to very tiny negative number

2021-01-11Process: drop commLenChristian Göttsche
It is only used on Linux to optimize memory handling in case the command changes to a smaller-or-equal string. This "optimization" however causes more code bloat and maintenance cost on string handling issues than it gains.

2020-12-19Split boilerplate and platform-independent field comparisonBenny Baumann
This acheives two things: - Allows for simple tie-breaking if values compare equal (needed to make sorting the tree-view stable) - Allows for platform-dependent overriding of the sort-order for specific fields Also fixes a small oversight on DragonFlyBSD when default-sorting.
2020-12-19Invert Process_compare resolution so that superclass matches run firstHisham Muhammad
* This removes duplicated code that adjusts the sort direction from every OS-specific folder. * Most fields in a regular htop screen are OS-independent, so trying Process_compare first and only falling back to the OS-specific compareByKey function if it's an OS-specific field makes sense. * This will allow us to override the sortKey in a global way without having to edit each OS-specific file.
