The cumulative wait time was as long as the delay itself in the
flush-on-size test, causing the test to pass because the write
managed to time out.
|
|
|
|
|
|
|
|
This also hides the module behind ?PRIM_FILE to make testing new
implementations less painful.

* rickard/time-unit/OTP-13831:
Replace usage of deprecated time units
|
|
Extend file_SUITE:read_write_file/1 to test file:write_file/3
which was not tested at all.
While we are it, remove the superfluous roundtrips tests of
term_to_binary/1 and binary_to_term/1. Those BIFs are tested
in detail in other test suites (for example, binary_SUITE in
emulator_test).

In 9870d22b2401b, the timetrap for large_write/1 was accidentally
reduced from the default 30 minutes to only 1 minute. That is not
enough for some older computers.
|
|
|
|
While we are it, also re-ident the files.
|
|
Remove out-commented code. Make sure that comments that are not
at the end of a line starts with two '%' characters and not just
one. That will become important later when we'll remove all
?line macros and ask Emacs to re-indent the files.
|
|
Those clause are obsolete and never used by common_test.
|
|
Replace with io:format/2 or ct:pal/3.
|

?config is ugly and not recommended. Use proplists:get_value/2
instead.
|
|
|
|
As a first step to removing the test_server application as
as its own separate application, change the inclusion of
test_server.hrl to an inclusion of ct.hrl and remove the
inclusion of test_server_line.hrl.

The OSE port is no longer supported and this commit removed it
and any changes related to it. The things that were general
improvements have been left in the code.

When it called the "file:position", it subtract the size that was
read into the buffer, and returns the value.
However, it has been discarded buffer and correct position is lost,
if "file:postion" returns error.

This option allows the caller not to go through the file server for information
about files guaranteed to be local.

Windows do not accept long UNC paths for current working directory.

The sync option adds the POSIX O_SYNC flag to the open system call on
platforms that support the flag or its equivalent, e.g.,
FILE_FLAG_WRITE_THROUGH on Windows. For platforms that don't support it,
file:open/2 returns {error, enotsup} if the sync option is passed in.
The semantics of O_SYNC are platform-specific. For example, not all
platforms guarantee that all file metadata are written to the disk along
with the file data when the flag is in effect. This issue is noted in the
documentation this commit adds for the sync option.
Add a test for the sync option. Note however that the underlying OS
semantics for O_SYNC can't be tested automatically in any practical way, so
the test assumes the OS does the right thing with the flag when
present. For manual verification, dtruss on OS X and strace on Linux were
both run against beam processes to watch calls to open(), and file:open/2
was called in Erlang shells to open files for writing, both with and
without the sync option. Both the dtruss output and the strace output
showed that the O_SYNC flag was present in the open() calls when sync was
specified and was clear when sync was not specified.

This is to avoid lingering files on windows.

The file module communicates with a file io server with the following
protocol for file operations:
> {file_request,From,ReplyAs,Request}
< {file_reply,ReplyAs,Reply}
The ReplyAs value is sent by the client side to match against when
receiving the reply and is otherwise left untouched and passed as is by
the server.
This commit enables receive optimizations by using the reference of the
server monitor, changing the protocol to:
> {file_request,From,MonitorRef,Request}
< {file_reply,MonitorRef,Reply}
As the shape of the messages is not changed, backwards compatibility is
not a concern.
