Giffunipfg@FreeBSD.org2017-11-20T19:49:47Zurn:sha1:8a16b7a18f5d0b031f09832fd7752fba717e2a97
Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Make stdio deferred cancel-safe.2017-06-29T14:44:17ZKonstantin Belousovkib@FreeBSD.org2017-06-29T14:44:17Zurn:sha1:fda0a14f4744c2851766f395775c7531e7c4f7dd
If used with fopen(3)/fdopen(3)-ed FILEs, stdio accurately uses
non-cancellable internal versions of the functions, i.e. it seems to
be fine with regard to cancellation. But if the funopen(3) and
f{r,w}open(3) functions were used to open the FILE, and corresponding
user functions create cancellation points (they typically have no
other choice), then stdio code at least leaks FILE' lock.
The change installs cleanup handler which unlocks FILE. Some minimal
restructuring of the code was required to make it use common return
place to satisfy hand-rolled pthread_cleanup_pop() requirements.

NetBSD, OpenBSD, and Android's Bionic all number the clauses 1 through 3,
so follow suit to make comparison easier.

Next stage of stdio cleanup: Retire __sFILEX and merge the fields back into2008-04-17T22:17:54ZJohn Baldwinjhb@FreeBSD.org2008-04-17T22:17:54Zurn:sha1:1e98f88776fc606df245a382685b1ac634a81389
__sFILE. This was supposed to be done in 6.0. Some notes:
- Where possible I restored the various lines to their pre-__sFILEX state.
- Retire INITEXTRA() and just initialize the wchar bits (orientation and
mbstate) explicitly instead. The various places that used INITEXTRA
didn't need the locking fields or _up initialized. (Some places needed
_up to exist and not be off the end of a NULL or garbage pointer, but
they didn't require it to be initialized to a specific value.)
- For now, stdio.h "knows" that pthread_t is a 'struct pthread *' to
avoid namespace pollution of including all the pthread types in stdio.h.
Once we remove all the inlines and make __sFILE private it can go back
to using pthread_t, etc.
- This does not remove any of the inlines currently and does not change
any of the public ABI of 'FILE'.

Associate a multibyte conversion state object with each stream. Reset it2004-05-22T15:19:41ZTim J. Robbinstjr@FreeBSD.org2004-05-22T15:19:41Zurn:sha1:87275e436a0fb31fea2757532860a3ec993d2cd6
to the initial state when a stream is opened or seeked upon. Use the
stream's conversion state object instead of a freshly-zeroed one in
fgetwc(), fputwc() and ungetwc().
This is only a performance improvement for now, but it would also be
required in order to support state-dependent encodings.
