+ Fixed Bugs and Malfunctions + + +

For the bit syntax, when matching with a size field that + is bound during the same matching, a warning for unused + variable was emitted. This bug has been fixed.

When parsing a badly formed file epp hangs. This + problem has been fixed.

Bugs concerning guards have been fixed in the Erlang + interpreter.

+

+ + +

The linter now checks the record name when calling the + function erlang:is_record/2.

+

Own Id: OTP-4886

+ + +

Guards of mach specifications are corrected to resemble + the semantics of guards in real code more closely. The + implementation now corresponds to the documentation in + ERTS User's Guide. The following things are corrected:

+ + Guard semantics was wrong when it came to logical + operators and exceptions. + {'or', {'is_integer','$1'}, {'or', '$1', '$1'}} + evaluated to true with '$1' bound to an + integer. + Unary + and - was not implemented + Calling operators as Bif's was not supported by + ets/dbg:fun2ms (erlang:'or'(A,B) etc) + Old typetests (like integer(X) instead of + is_integer(X)) was not supported by + ets/dbg:fun2ms + Semicolon (;) in guards was not supported by + ets/dbg:fun2ms + +

A bug that could cause a crash has been fixed in the + file_sorter module. The crash could only occur + when sorting or merging to a file and the input function + returned {end_of_input, Value}.

+

Own Id: OTP-5009

+ + +

A function clause exit in filelib:fold_files/5 has + been fixed.

+

Own Id: OTP-5137

+ + +

filelib:fold_files/5 has been fixed to not include + directories that match the regular expression in the + result. In this process, filelib:is_regular/1 has + been added to the module.

+

WARNING the behaviour of filelib:fold_files/5 has + also been changed so the regexp match is tried not on + the full name, but locally in each traversed directory.

+ +
+ Improvements and New Features + + +

The initial shell process started in parallel with the + init boot process. This made it possible to pipe + commands to the shell that got evaluated before the system + had booted properly. Also the shell was normally accessible + before .erlang had been evaluated and this caused + problems especially related to code loading. This has now + been fixed so that the initial shell is not accessible + until after the init boot routine has finished and + .erlang has been evaluated. Note that the shell + starts before any -s arguments are executed.

+

Own Id: OTP-4877

+ + +

It is now possible to compile files with erlc without + getting a lot of (for compilation) unnecessary code + loaded and executed (like distribution, inet config, + etc). erlc now also calls erl with -boot start_clean (so that SASL is not started even if + start_sasl is default boot script).

+

Own Id: OTP-4878

+ + +

Dets tables can now be opened or closed in parallel. In + particular, if some table is being repaired, other tables + can still be opened or closed.

+

Own Id: OTP-4908

+ + +

The new STDLIB module qlc implements a query + language with a list comprehension syntax completely + embedded in Erlang. There is support for reading data + from ETS, Dets, and Mnesia tables as well as for defining + other sources of data. For easy testing queries can be + stated in the Erlang shell. The qlc module aims at + replacing Mnemosyne. See qlc(3) for details and + examples.

+

Own Id: OTP-5043

+ + +

Some support for records has been added to the Erlang + shell. There are commands for reading record definitions + from files and for manipulating record definitions in the + shell. The record syntax can be used in the shell and + return values are printed as records when possible using + the records definitions known to the shell. New commands + in the shell are rd/2, rf/0,1, + rl/0,1, rp/1, and rr/1,2,3. Existing + functions in user_default.erl with any of these + names need to be renamed. See shell(3) for further + details.

The new function dets:repair_continuation/2 can be + used for restoring an opaque continuation returned by + dets:select/1 or dets:select/3 if the + continuation has passed through the external term format + (been sent between nodes or stored on disk).

+

Own Id: OTP-5126

+ + +

A new function, string:to_float/1, has been added.

+ STDLIB 1.12.8 + +
+ Improvements and New Features + + +

The functions ets:insert_new/2 and + dets:insert_new/2 are added. Please consult + the manual pages for details.

+

Own Id: OTP-5075

+ + +

New function: proc_lib:hibernate/3. Processes spawned + using proc_lib (also indirectly, such as + gen_server process), should use this function + instead of the BIF erlang:hibernate/3 directly to + ensure that the exception handler for the process continues + to work when the process is awaken.

+ STDLIB 1.12.6 + +
+ Fixed Bugs and Malfunctions + + +

If many files or sockets were open (more than 256), + beam_lib operations could fail. Corrected.

+ +
+ STDLIB 1.12.5 + +
+ Fixed Bugs and Malfunctions + + +

When opening a Dets table read only an attempt was made + to re-hash the table resulting in an error message. This + problem has been fixed.

+

+ + +
+ +
+ Improvements and New Features + + +

If a gen_server, gen_event or gen_fsm + process exits with {undef,[{M,F,A}|...]}, the error + report will now state if the function call failed because + the module could not be loaded or because the function was + not exported.

+ +
+ STDLIB 1.12.4 + +
+ Fixed Bugs and Malfunctions + + +

The shell function c:regs() did crash if there was + a registered port among the registered names. This is now + corrected.

+

Own Id: OTP-4890

+ + +

A bug has been fixed in dets: not all objects were + always visible in tables with more than 131072 keys.

+

Own Id: OTP-4906

+ + +

A bug has been fixed in dets: when trying to + repair a version 9 table, a not_a_dets_file error + message was returned unnecessarily often.

+

Own Id: OTP-4907

+ + +
+ +
+ Improvements and New Features + + +

Starting Erlang with the +Bi flag (to ignore ^C), now + also disables the quit ('q') option in the JCL menu.

+ STDLIB 1.12.3 + +
+ Fixed Bugs and Malfunctions + + +

A bug in erl_scan caused the compiler to hang when + end-of-file in a comment was encountered. This is now + corrected.

+

+ + +

The linter now reports errors for unsafe variables when + the option nowarn_unused_vars is given.

gen_server:cast/2 now crashes for invalid + arguments.

+

gen_server:abcast/2-3 now crashes for invalid + arguments. The behaviour when casting to the name + global has been corrected. Previously, + gen_server:abcast(global,[node@host]) tried to + cast to the globally registered name node@host, + which is more of a bug than less. Now such a call will + cast to the registered name global at the node + node@host as (probably) expected.

+

An rpc:call/5 and rpc:block_call/5 having a + timeout argument has been added.

+

rpc:abcast/2-3 has been improved not to get stuck + waiting for connection setup if the remote node is not + connected. In this case the send is spawned off to a + temporary process.

+

Two typos in the docs for module calendar has + been corrected thanks to Bengt Kleberg.

+ +
+ STDLIB 1.12.2 + +
+ Fixed Bugs and Malfunctions + + +

gen_server: the internal function get_parent, + called by gen_server:enter_loop/[4,5], now returns + the pid of parents that are registered processes, instead of + returning their name. The reason for this is that + gen_server relies on that the parent is represented + as a pid. This error in get_parent/0 had the effect + that the terminate function of the child was not run when + it was shutdown.

+ STDLIB 1.12.1 + +
+ Fixed Bugs and Malfunctions + + +

The code server could hang if invoked early in the startup. + For example if the emulator was started with + "-s file eval Filename and Filename contained + a call to code:add_patha/1 the code server + accidentally tried to execute code in an unloaded module + from inside the code that loaded a module - hence hangup. + This bug has now been fixed.

+

Note! Starting Erlang through code loading from a remote + Erlang boot server will not work after this patch. It will + be fixed in a later patch. Rumours has it that remote boot + server code loading did not work before this patch either. + It is not a commonly used feature.
