The correction is due to the the evil testcase
dets_SUITE:simultaneous_open(). If the process repairing a Dets file
is killed (should normally never happen), and another process tries to
repair the file, a temporary file from the first process could live on
for a while, even after a successful call to file:delete(). This has
only been seen on W-nd-ows, where it is a known problem.
There are other ways to deal with the problem (rename the file; use
some other filename), but we continue using one certain filename in
order to be as backwards compatible as possible.

The appup tests for kernel, stdlib and sasl tests that the appup file
allows upgrade from the previous and current major release to the
current release. If, in the current release, the application version
was not changed compared to the previous release, then we would still
test that the appup supported the upgrade (i.e. from current release
to current release). This is now changed, in order to avoid test
failures on patch releases where kernel, stdlib and sasl are not
changed.

This commit complements 769996c0cd4cb68c157e39de725642f209ed7423 and
adds tests for the following problems introduced by
f11aabdc9fec593c31e6c4f3fa25c1707e9c35df:
Given the symlink 'dirlink' pointing to an existing dir, then
- filelib:is_regular("dirlink") -> false
- filelib:is_dir("dirlink") -> false
Given the symlink 'filelink' pointing to an existing file, then
- filelib:is_regular("filelink") -> false
- filelib:is_file("filelink") -> false
- filelib:last_modified("filelink") and filelib:filesize("filelink")
return the info of the link and not the file
Given the symlink "broken_symlink" pointing to a non-existing file, then
- filelib:wildcard("broken_symlink",File) -> []
|
|
This fixes a bug introduced in f11aabdc9fec593c31e6c4f3fa25c1707e9c35df where
filelib:eval_read_file_info/2 was made to use file:read_link_info/1 to never
follow symlinks. This fixed wildcard/1 but broke every other function using
eval_read_file_info/2.

Thanks to Alexei Sholik for reporting the bug.

This is a partial revert of 05c4d31b2c5c5f6ade7d91b55c598fe7fa58e509 in
which a new macro `?STR()` was introduced. This macro shouldn't be used in
scan_number/6 and scan_based_int/6 because the length of the string is
needed when computing column numbers through tok3/8.

The POSIX standard for tar says that there must be at least
two 512-bytes zero blocks at the end of the tar archive file.
Our implementation would only emit a single 512-byte zero block if the
size of the last file was in the range 18*512 through 19*512-1 (modulo
20*512). GNU tar would correctly unpack such tar archive file, but
would emit a warning:
tar: A lone zero block at 20

filelib:wildcard() should show broken symlinks

Reported-by: José Valim

Add test of update instructions from current major to current
minor. Earlier only previous major to current was tested.
|

When redefining and exporting the type map() erl_lint erroneously
emitted an error. This bug has been fixed.

filelib:wildcard("broken_symlink") would return an empty list if
"broken_symlink" is a symlink that does not point to an existing
file.

Stabilize tests for all kind of machines
Old sparc (and newer smaller) machines timeouts in 'random_ref_comp'
decrease load and increase timeouts.
Supervisor:
Turn up accepted time, since if non-linear it should be much worse,
now the test failes on slow multicore machines
Remove memory tests, they fail sometimes and those tests are not
needed to be tested. Hard to predict GC's and other processes behaviours.

* vinoski/sys-get-rep-state2:
remove tuple funs from special process documentation
fix sys:get_state/1,2 and sys:replace_state/2,3 when sys suspended
OTP-11817
|
|
The 'encoding' option of erl_parse:abstract/2 has been extended to
include 'none' and a callback function (a predicate).
The rationale is that a more general means of determining what integer
lists are to be represented as strings may help readability when
generating Erlang code given input in some other encoding than Latin-1
or UTF-8.
|
|
The grace period is over.
|
|
|
|
Add two new system callbacks Module:system_get_state/1 and
Module:system_replace_state/2 to allow sys:get_state/1,2 and
sys:replace_state/2,3 to operate correctly even if a process is sys
suspended. Modify gen_server, gen_fsm, and gen_event to support the new
callbacks.
If a callback module does not export these functions, then by default the
Misc value (the same as that passed as the final argument to
sys:handle_system_msg/6, and returned as part of the return value of
sys:get_status/1,2) is treated as the callback module's state.
The previous behaviour of intercepting the system message and passing a
tuple of size 2 as the last argument to sys:handle_system_msg/6 is no
longer supported.
Add tests to verify the correctness of sys:get_state/1,2 and
sys:replace_state/2,3 when processes are sys suspended. Add two tests for
modules that implement special processes, one that exports
system_get_state/1 and system_replace_state/2 and one that doesn't.
Much of the credit for this patch goes to James Fish, who reported the
initial problem and implemented much of the fix.

* bjorn/compiler/utf8-warning/OTP-11791:
Don't fail compilation for modules that contain invalid UTF-8
epp: Make it possible to specify a default encoding
|
|
In the next commit, we will need a way to tell epp which the
default encoding should be for files that have no encoding comment.
We could add new open() and parse_file() functions with one
extra argument for the encoding, but there are already too many
variants.
To avoid having to add an additional argument to epp:open() and
epp:parse_file() each time new options are needed, introduce
epp:open/1 and epp:parse_file/2 that takes a property list with
options. Also support the new 'default_encoding' option for specifying
the default encoding for source files.
Thanks to Richard Carlsson for the idea and the implementation
of the new functionality in epp.erl.
