* watch: Fix buggy line-deletion behaviour with --no-linewrapJustin Gottula2023-01-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is largely based upon Justin's patch, I just moved the reset_ansi() parts out otherwise you get strange colour reset behaviours. Original patch message: I used the --no-linewrap (-w) option for the first time today, watching some wide output that didn't quite fit in my tmux pane. Quickly I noticed a problem: while --no-linewrap did indeed eliminate the spillover of lines too long for the terminal "window" width, it *also* resulted in a bunch of lines from the program output being hidden entirely. After some fiddling around, the exact problematic behavior appears to be as follows: 1. Lines which would have wrapped (more than $COLUMNS chars long) are handled correctly. 2. Lines which would *not* have wrapped (shorter than $COLUMNS) are printed; but then the next line is *not* printed! For long sequences of non-wrap-length lines, you get an every-other-line-is-visible sort of effect. The logic underlying the problem seems to be this: in the run_command loop, if the x loop goes all the way to completion (meaning we've reached the right-side edge of the window area), there's a small block of code for --no-linewrap whose main purpose is to call find_eol, which eats input until it hits a newline (or EOF). Clearly this is intended to be done for lines that are too long, so that the excess characters are discarded and the input pointer is ready to go for the subsequent line. However, this code isn't in any way conditional on the value of eolseen! Short/wouldn't-wrap lines will have encountered a newline character before exhausting the entire x loop, and therefore eolseen will be true. Long/would-wrap lines will not have encountered a newline when the x loop is exhausted, and so eolseen will be false. Nevertheless, find_eol is called in *both* cases. For long lines, it does what it's meant to do. For short lines, *the newline has already been encountered and dealt with*, and so the actual effect of find_eol is to eat the entirety of the next line, all the way through to its newline, such that it isn't printed at all.

* top: include the '5' toggle on the primary help screenJim Warner2023-01-151-1/+2
| | | | | | | | | | | | | | | | | | | | | When the p/e-cores support (via the '5' key) was added in the patch referenced below, I intentionally omitted that key from the top primary help screen. This seemed appropriate since it only applied to select Intel cpus and, besides, that screen was getting kind of crowded. [ it remains an objective to fit on a 80x24 terminal ] Upon reflection, I found a way to squeeze it into that help screen and have decided to included it. Hopefully its presence will encourage use of top's new provision on any Intel platforms that distinguish between cores.

| | | | | | | | | | | | | | | | | | If procps is built on a Linux 5.3+ system then pidwait is built with pidfd_open(). If that program is run on a system < 5.3 then it gives an odd generic error.

* sysctl: print dotted keys againCraig Small2022-04-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | When the globbing update was put into sysctl, you could no longer simply use the keys because one key could potentially be multiple paths once the glob expansion occured. Using the path instead gave a unique output. Except certain programs, such as salt, expected the output to use the dotted path "kernel.hostname" and not "kernel/hostname". We can no longer use the original key, so now for each path: Copy the path strip off /proc/ convert all / to . The sysctl testsuite was also updated to check for a few different types of conversion failures.

* free: Use wstr width and not lengthCraig Small2022-02-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous commit used the value from mbstowcs() to work out the spacing required, as printf() got it completely wrong. However, for alignment of text you don't use the string length but the string width. As the referenced website says: Use wcslen when allocating memory for wide characters, and use wcswidth to align text. Which is what free does now. Chinese is still off by one but I cannot see why this is so. It's close enough for now. If someone can work it out, I'd love to know what the fix is. As a side effect, #213 is fixed because we are putting the correct number of spaces in. French is still an issue (see #24 ) but this is because the string is too long!

* free: Fix first column justificationCraig Small2022-01-311-0/+1
| | | | | | | | | | | | | | | | | | | free has for many years had a problem with translated header columns or the first column. This is because printf("-9s", str) doesn't use the wide length of the string but the char length meaning they are mis-aligned. Using the mbstowcs() function to get the wide length and then a precision parameter to append the right number of spaces after the number means we get what we need.

* pgrep: Match on cgroup v2 pathsCraig Small2021-10-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | You can match or filter on cgroup paths. Currently the match is only done for version 2 cgroups because these are way simpler as they have a unified name and always start with "0::". cgroup v1 can have: named groups "1:name=myspecialname:" controllers "9:blkio:" multiple controllers! "4:cpu,cpuacct:" So they are very much more complicated from a options parsing and cgroup matching point of view.

* fix uid/gid > 2^31Todd Lewis2021-10-261-0/+1
| | | | | | | | | | | | | | | | This MR revisits a partial fix from 2018. The problem stems from incorrect handling of unsigned 32-bit uid_ts and gid_ts as signed when values are large - i.e. when the high bit is set. In that case, pgrep and pkill fail to identify processes by uid. (They succeed when finding the same processes by username.) The primary fix for this is to impliment the "FIXME" comment in proc/readproc.h, the implementation of which allows the removal of the (int) casts from the partial fix from 2018. The other fixed code in this MR consists of tests in strict_atol() that detects and errors out on overflows. References: Merge !146
