Sridhar Ratnakumar 0758578f6c gotail: add -p argument to use polling 2013-05-29 15:07:53 -07:00
Sridhar Ratnakumar 499e541b19 copytruncate should work even if ReOpen is False.
at least, `tail -f` (not `tail -F` which is analogous to ReOpen)
reopens truncated files.

this change introduces the FileChanges struct to abstract the change
notifications for file changes, deletions and truncations.

this is what caused the test to hang occasionally. after this fix,
test completes in 2mins all the time.

Sridhar Ratnakumar b664e9fc9d Merge pull request #6 from srid/bug99139_copytruncate
copytruncate support,

truncation detection for both inotify and polling file watchers along with test cases, plus a fix for issue #5.

Sridhar Ratnakumar 976fc15b81 update change log, gofmt and remove debug prints 2013-05-28 14:01:32 -07:00
Sridhar Ratnakumar 644891ebbc BlockUntilExists should return immediately if the file already exists
this fixes a potential race condition in the use of BlockUntilExists
following a file existence check (as we do in tail.go:reopen).

closes issue 5
2013-05-28 13:29:40 -07:00
Sridhar Ratnakumar fb37e0b7ca use a smaller poll duration for faster test runs 2013-05-28 12:55:11 -07:00
Sridhar Ratnakumar c90cd7b8db add truncation detection to PollingFileWatcher 2013-05-28 12:54:53 -07:00
Sridhar Ratnakumar 5ccafcc3d6 fixes on top of Florian's truncation detection (1ff299bc2)
* initialize `Size` with the then-size of the file when ChangeEvents
  is called. remember that this function is expected to be called many
  times, one after another. this also passes the TestReSeekInotify
  test.

* do not ignore errors from os.Stat. we panic errors like these now,
  but ideally should switch to tomb.Tomb for letting the user handle
  them.
2013-05-28 12:31:46 -07:00
Sridhar Ratnakumar 8c443fb067 fix truncation tests
* use O_TRUNC to actually truncate
* use longer initial data before truncating

truncated and updated file is expected to be of smaller size, else
truncation detection won't work.
