2019-08-23estream: Fix gpgrt_poll at EOF.NIIBE Yutaka1-1/+1
* src/estream.c [HAVE_POLL_H] (_gpgrt_poll): Catch POLLHUP event for want_read. -- At EOF, here is a difference of semantics between poll(2) and select(2).

2019-07-25estream: Fix IS_INVALID_FD.NIIBE Yutaka1-5/+1
* src/estream.c (IS_INVALID_FD): Simply compare to -1. -- Perhaps, when it was written at first, use of HANDLE was in mind. Now, we have different set of methods for Windows, and this macro is only for integer fd access, no need of ifdef/endif. Signed-off-by: NIIBE Yutaka <[email protected]>

2019-01-04core: New functions gpgrt_abort and gpgrt_add_emergency_cleanup.Werner Koch1-9/+8
* src/init.c (emergency_cleanup_list): New gloabl var. (_gpgrt_add_emergency_cleanup): New. (_gpgrt_abort): New. Repalce all calls to abort by this. Also replace all assert by either log_assert or a stderr output followed by a _gpgrt_abort. (run_emergency_cleanup): New. * src/visibility.c (gpgrt_add_emergency_cleanup): New public API. (gpgrt_abort): New public API. -- Libgcrypt uses its own assert function which makes sure to terminate the secure memory. This is safe as log as an assert is triggered internally in Libgcrypt. GnuPG runs emergency cleanup handlers right before log_fatal etc to tell Libgcrypt to terminate the secure memory. With the move of the logging function to gpgrt in gnupg 2.3 this did not anymore. Thus we now provide a mechanism in gpgrt to do right that. Eventually Libgcrypt can also make use of this. What this does not handle are calls to abort or failed asserts in external libraries or in libc. We can't do anything about it in a library because a library may not setup signal handlers.

2018-11-26core: New functions gpgrt_fprintf_sf anf gpgrt_fprintf_sf_unlocked.Werner Koch1-5/+8

(do_print_stream): Ditto. * tests/t-printf.c (stream_to_string): New. (struct sfstate_s): New. (string_filter): New. (check_fprintf_sf): New. (main): Call new test. -- The actual reason to implement these functions is to enhance the internal logging function with a filter to sanitized strings so that control values or other things can be quoted.

2018-11-26core: Add a limited version of gpgrt_ftruncate.Werner Koch1-0/+31

2017-05-31Align 'es_poll' semantics closer with POSIX.Justus Winter1-3/+0
* src/estream.c (_gpgrt_poll): Do not return early if some streams are found to be ready before even polling the others. -- POSIX mandates that all streams are examined and returning early violates that. It also imposes an order on how the callee serves the streams, which might be incompatible with the order the callee wants to serve them, leading to deadlocks.

2017-02-28w32: Fix gpgrt_poll for Windows.Werner Koch1-6/+0
* src/estream.c (_gpgrt_poll) [W32]: Do not call the syscall clamp. -- The system call clamp may only be used directloy around system calls. We don't need them here because we use independent threads to implement non-blocking behaviour. In fact the clamp may lead to a deadlock. Signed-off-by: Werner Koch <[email protected]>

2016-06-15estream: Fix assertion failure due to es_flush.NIIBE Yutaka1-3/+1
* src/estream.c (es_writen): Set writing flag even if no data was written. -- GnuPG-bug-id: 2371 Signed-off-by: Werner Koch <[email protected]> gniibe tracked the problem down to a fully valid change in GnuPG (gnupg commit 12af2630cf4d1a39179179925fac8f2cce7504ff). He wrote: This is the first instance for estream to do READ and WRITE (in the history of the code > 10 years :-). In the [gnupg] function agent_write_private_key, the pattern is: es_fopen es_fread es_fseek es_fwrite which should work well, but if results core dump by assertion failure in the function es_flush of libgpg-error.
