Joe Thornber	7f97c7ea9a	build: Don't generate symlinks in include/ dir ... As we start refactoring the code to break dependencies (see doc/refactoring.txt), I want us to use full paths in the includes (eg, #include "base/data-struct/list.h"). This makes it more obvious when we're breaking abstraction boundaries, eg, including a file in metadata/ from base/	2018-05-14 10:30:20 +01:00
David Teigland	bbb8040456	dev_cache: drop open_list ... devices are now held open only in bcache, so drop the dev_cache list of open devices which is unused.	2018-05-11 12:47:56 -05:00

Zdenek Kabelac	f6dd5a294b	exec: pipe open ... Function replaces popen() system and avoids shell execution and argument parsing (no surprices).	2013-08-06 16:18:43 +02:00
Zdenek Kabelac	b6437a6180	cleanup: update exec_cmd comment and error ... Use log_sys_error for reporting error of system call. Fix comment for return value.	2013-08-06 16:16:57 +02:00

Zdenek Kabelac	5f3f06db66	Move debug message ... so it does not look like we are executing command in the middle of critical_section in log trace.	2011-09-19 12:48:02 +00:00
Zdenek Kabelac	586f310618	Remove meaningless const type qualifiers on cast type ... Static analyzis noticed we do not really need them - so removing.	2011-08-04 14:30:51 +00:00
Zdenek Kabelac	b1b38215ba	Add exec_cmd paramater sync_needed ... As sync_local_dev_names() cannot be called within activation context, add new parametr which allows to select if the sync call is needed before executing new command.	2011-01-13 14:51:32 +00:00
Alasdair Kergon	a8de276520	Replace fs_unlock by sync_local_dev_names to notify local clvmd. (2.02.80) ... Introduce sync_local_dev_names and CLVMD_CMD_SYNC_NAMES to issue fs_unlock.	2011-01-12 20:42:50 +00:00

Zdenek Kabelac	ad50450a22	Avoid cookie sharing between forked processes ... Before fork, ensure cookie is reset so it's not shared between processes.	2011-01-10 19:31:02 +00:00
Zdenek Kabelac	2955b913ea	Use new status code from fsadm check ... Patch updates exec_cmd() and adds 3rd parameter with pointer for status value, so caller might examine returned status code. If the passed pointer is NULL, behavior is unmodified. Patch allows to confinue with lvresize if the failure from fsadm check is caused by mounted filesystem as many of filesystem resize tools do support online filesystem resize. (originally user had to use flag '-n' to bypass this filesystem check)	2010-11-01 14:17:35 +00:00
Mikulas Patocka	3395d72881	Change exit() to _exit() in the child process. exit flushes stdio file buffers, ... _exit doesn't. If there were some open files, an error in exec and subsequent exit() would cause the buffers to be flushed twice. Example: #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <sys/wait.h> int main() { printf("buu"); if (!fork()) { execl("/bin/true-not-exists", "/bin/true", NULL); exit(1); } wait(NULL); return 0; } Signed-off-by: Mikulas Patocka <mpatocka@redhat.com --- daemons/dmeventd/libdevmapper-event.c | 2 +- lib/misc/lvm-exec.c | 2 +- test/harness.c | 3 ++- tools/dmsetup.c | 2 +- 4 files changed, 5 insertions(+), 4 deletions(-)	2009-07-13 21:26:41 +00:00

Zdenek Kabelac	c8669f6b13	Fixed bug where lvresize option -t was not properly passed to fsadm. ... Using argv[] list in exec_cmd() to allow more params for external commands. Fsadm does not allow checking mounted filesystem. Fsadm no longer accepts 'any other key' as 'no' answer to y/n. Fsadm improved handling of command line options.	2009-02-24 15:48:00 +00:00
