Andrew Wood de2fe7f6be Correct the O_DIRECT flag setting to use the output file descriptor rather than assuming stdout. 2024-10-05 14:17:15 +01:00
Andrew Wood c548d1f2d8 Add a "--gauge" option which alters the progress bar to show the current rate as a percentage of the max rate seen, if the size is unknown (#46). 2024-10-04 22:15:14 +01:00
Andrew Wood 208ac286f8 Calculate rate_min, rate_max, etc, regardless of whether show_stats is true, since the overhead is minimal and it will allow us to use that information for other options later. 2024-10-04 20:15:15 +01:00
Andrew Wood 9aef419c4c Surround the "--average-rate" average rate with brackets rather than square brackets, to differentiate it from the "--rate" current rate. 2024-10-04 19:59:21 +01:00
Andrew Wood a2c6490d31 Prefix the estimated completion time of "--fineta" with "FIN" rather than "ETA" to differentiate it from the "ETA" provided by "--eta" (#43). 2024-10-04 19:45:08 +01:00
Andrew Wood 4b399995f5 Allow --rate to be used with --numeric (#17). 2024-10-04 19:08:02 +01:00
Andrew Wood 877bb1f91f Move calculation code into its own file, to make display.c smaller and keep it focused purely on display. 2024-10-04 17:22:43 +01:00
Andrew Wood cd696e60ab Make pv__calc_percentage() into pv_percentage() in number.c instead of a static function in display.c, so it can be used in multiple places in future. 2024-10-04 17:15:18 +01:00
Andrew Wood 9bd5a518ea New option "--stats", to show a line of statistics about the transfer once it has ended (issue #49). 2024-10-04 15:12:22 +01:00
Andrew Wood 65d568c283 Refactor display and calculation functions to separate them out more cleanly, move more information into the state structure instead of repeating it as function parameters, and fix a memory leak in the whole-PID mode of --watchfd. 2024-10-04 13:27:17 +01:00
Andrew Wood a118f110fa Use verbose variable names for readability. 2024-10-04 11:58:57 +01:00
Andrew Wood f803f29158 Move transfer rate calculations into their own function, and make pv__format stand alone, to maintain separation of concerns. 2024-10-04 11:54:47 +01:00
Andrew Wood 954c2d32c1 Move calculated values out of state.display into a new structure, state.calc, to separate out the display portion from the calculation portion; and move history_interval into state.control, as it is a control parameter set at the start. 2024-10-04 11:08:01 +01:00
Andrew Wood 545769885d Raise a SIGCONT to the whole process group after receiving a SIGTTOU, so that pipelines can be resumed in the background (for example "pv /dev/zero | cat > /dev/null" can now be suspended and put into the background - if we do not send that signal then "cat" remains stopped, as mentioned in issue #56). 2024-10-04 10:24:08 +01:00
Andrew Wood 94ea82c10a Indentation correction. 2024-10-04 10:21:23 +01:00
Andrew Wood a6c978573f Move pv_write_retry() and pv_tty_write() from cursor.c to display.c so they sit with all the other display functions. 2024-10-04 09:06:24 +01:00
Andrew Wood 9a639b40b7 Use gmtime() instead of localtime() in debugging output to avoid lockups in signal handlers due to time zone lookups. 2024-10-04 08:53:14 +01:00
Andrew Wood e84f47abc8 Refactor handling of TTOU so that instead of shuffling stderr to another file descriptor and using /dev/null when backgrounded, we set a flag to suspend terminal output, and perform all terminal writes through a new pv_tty_write function which checks that flag. 2024-10-03 23:03:31 +01:00
Andrew Wood 52a720ec33 Improve the readability of the code that handles SIGTTOU. 2024-10-03 22:08:11 +01:00
Andrew Wood 23bd296aeb Re-order structure members to minimise padding / holes, after analysis with "pahole" on a 64-bit system. 2024-10-03 21:25:41 +01:00
Andrew Wood 69a56ced7a Correct double-free on exit when using --watchfd - issue #96. 2024-09-07 21:04:09 +01:00
Andrew Wood 60936080da Move the "--size @FILE" file size reading into its own function for clarity; standardise its error message format to "program: file: message: detail"; uniquely name variables; refuse to accept a directory as a file; and with this option, try reading the size of a block device from sysfs if we can, to avoid requiring read permissions on the device. 2024-08-06 23:17:15 +01:00
Alexander Perlis f6b0ddc0b3 Support block devices in @-syntax 2024-08-01 00:36:02 +00:00
Andrew Wood e4ab8c56a0 Minor adjustment to comments. 2024-07-17 07:41:48 +01:00
Eric A. Borisch 3fdfd07443 Improve description and comments for blocking-write() after select() 2024-07-16 23:39:15 -05:00
Andrew Wood d801cdd722 Remove spurious strerror() call from debug report. 2024-07-16 22:44:10 +01:00
Andrew Wood 72e5078ce9 Move the MAKE_OUTPUT_NONBLOCKING code to state.c, as it can no longer work in main.c due to accessing internal structures; but still leave it switched off by default for now. 2024-07-16 22:41:31 +01:00
Andrew Wood a7c3f3dd35 Write the error from write() to the debugging output if nwritten is <0. 2024-07-16 22:23:51 +01:00
Andrew Wood 12f0312b00 Move the "stop at size" option setting to before the size calculation, otherwise if the size calculation tries to override that setting, it cannot do so (#91). 2024-07-16 21:58:47 +01:00
Andrew Wood 8c0e3e9dad When checking how many bytes were written, place the constant to the left of the equality check to match the rest of the code (this avoids accidental assignment if one equals sign is accidentally written instead of two), and write the appropriate debug message depending on whether the write was interrupted or it was empty. 2024-07-16 21:54:13 +01:00
Andrew Wood c7104f0c0d Merge pull request 'src/pv/transfer.c: timer going off returns with total_written==0; which is not an error.' (#92) from eborisch/pv:write-can-return-0 into main

Andrew Wood f8fc5844b1 Re-order the output file descriptor setting and the size detection to correct the problem with output block device size detection that was broken in 1.8.10 (#91). 2024-07-16 21:39:29 +01:00
eborisch d86d8cf65a Clarify state. 2024-07-16 03:57:11 +00:00
eborisch 11e5b5fe95 src/pv/transfer.c: write(2) returning 0 is not an error 
This is being hit easily on FreeBSD with pv sitting in a zfs send/recv pipeline. As write(2) returning 0 is not an error, handle it similar to returning -1 with EINTR or EAGAIN: wait a bit and try again.

Martin Dørum 30763684b7 add -o/--output option 2024-06-08 14:31:19 +02:00
Andrew Wood ace8f44f59 Added more debugging to stdout writes. 2024-05-11 21:13:12 +01:00
Andrew Wood 98994bbeaa Correct the copyright year in the "--version" output. 2024-04-22 22:25:22 +01:00
Andrew Wood b375041790 Correct issues #34, #86, #87 - progress output stopping when writing output data blocks - by adding a SIGALRM handler, since ignoring the signal prevents it from interrupting writes; and use setitimer() where available, instead of alarm(), to provide sufficient granularity to handle the case where the --interval is not a whole number of seconds. 2024-04-21 13:54:01 +01:00
Andrew Wood 3a41665302 Fix incorrect "%lf" string format. 2024-04-21 12:02:35 +01:00

Andrew Wood c9dede08d4 Adjust the decimal units flag variable name from "si" to "decimal_units" so it does not overlap with other words like "size" and "signal"; add man page entry and adjust the "-L" man page entry; and allow this flag to also change how input prefixes are processed. 2024-03-19 22:17:43 +00:00
