2016-04-16journald: rewrite function with switch, fix handling of -ESHUTDOWNZbigniew Jędrzejewski-Szmek
The comments and the log messages are next to one another, so it's easier to check that the messages match the comments. The sign was omitted in the check for -ESHUTDOWN, so it was never matched.
2016-04-08journal: assert gcry_mpi_scan succeededZbigniew Jędrzejewski-Szmek
It might be nicer to propagate the error to the caller, but that'd be a bigger refactoring. This shouldn't really fail, so just add an assert. CID #1349697.

2016-04-02test-compress-benchmark: fix argument parsing on 32bitZbigniew Jędrzejewski-Szmek
The patch is not minimal, but a function to parse size_t is probably going to come in handy in other places, so I think it's nicer to define a proper parsing function than to open-code the cast.

tree-wide: merge pager_open_if_enabled() to the pager_open()
2016-02-26tree-wide: merge pager_open_if_enabled() to the pager_open()Alexander Kuleshov
Many subsystems define own pager_open_if_enabled() function which checks '--no-pager' command line argument and open pager depends on its value. All implementations of pager_open_if_enabled() are the same. Let's merger this function with pager_open() from the shared/pager.c and remove pager_open_if_enabled() from all subsytems to prevent code duplication.

journal: restore offline state on error
2016-02-22tree-wide: make ++/-- usage consistent WRT spacingVito Caputo
Throughout the tree there's spurious use of spaces separating ++ and -- operators from their respective operands. Make ++ and -- operator consistent with the majority of existing uses; discard the spaces.
2016-02-22journal: restore offline state on errorVito Caputo
If we fail to create the thread, technically we should leave the offline_state as OFFLINE_JOINED, not OFFLINE_SYNCING.
2016-02-19journal: defer journal closes on rotateVito Caputo
When we rotate journals, we must set offline and close the current one, but don't generally need to wait for this to complete. Instead, we'll initiate an asynchronous offline via journal_file_set_offline(oldfile, false), and add the file to a per-server set of deferred closes to be closed later when they won't block. There's one complication however; journal_file_open() via journal_file_verify_header() assumes that any writable journal in the online state is the product of an unclean shutdown or other form of corruption. Thus there's a need for journal_file_open() to be aware of deferred closes and synchronize with their completion when opening preexisting journals for writing. To facilitate this the deferred closes set is supplied to the journal_file_open() function where the deferred closes may be closed synchronously before verifying the header in such circumstances.
2016-02-19journal: asynchronous journal_file_set_offline()Vito Caputo
This adds a wait flag to journal_file_set_offline(), when false the offline is performed asynchronously in a separate thread. When wait is true, if an asynchronous offline is already in-progress it is restarted and waited for. Otherwise the offline is performed synchronously without the use of a thread. journal_file_set_online() cancels or waits for the asynchronous offline to complete if in-flight, depending on where in the offline process the thread happens to be. If the thread is in the fsync() phase, it is cancelled and waiting is unnecessary. Otherwise, the thread is joined before proceeding. A new offline_state member is added to JournalFile which is used via atomic operations for communicating between the offline thread and the journal_file_set_{offline,online}() functions.

2016-02-18journal/catalog: fix memory leaksZbigniew Jędrzejewski-Szmek
Various buffers were lost because finish_item() either consumed the buffer or allocated a new one (if an entry with the same key existed). The caller would simply forget the buffer in either case. Also add a check for the case when a valid identifier is followed by an empty body. We should not allow this. Also be more consistent in error handling and always print an error message.

2016-02-11Move initialize_libgcrypt to separate fileZbigniew Jędrzejewski-Szmek
It's annoying to have the exact same function in three places. It's stored in src/shared, but it's not added to the library to avoid the dependency on libgcrypt.
2016-02-11Add memcpy_safeZbigniew Jędrzejewski-Szmek
ISO/IEC 9899:1999 §7.21.1/2 says: Where an argument declared as size_t n specifies the length of the array for a function, n can have the value zero on a call to that function. Unless explicitly stated otherwise in the description of a particular function in this subclause, pointer arguments on such a call shall still have valid values, as described in 7.1.4. In base64_append_width memcpy was called as memcpy(x, NULL, 0). GCC 4.9 started making use of this and assumes This worked fine under -O0, but does something strange under -O3. This patch fixes a bug in base64_append_width(), fixes a possible bug in journal_file_append_entry_internal(), and makes use of the new function to simplify the code in other places.

2016-02-09journal: Drop monotonicity check when appending to journal fileKlearchos Chaloulos
Remove the check that triggers rotation of the journal file when the arriving log entry had a monotonic timestamp smaller that the previous log entry. This check causes unnecessary rotations when journal-remote was receiving from multiple senders, therefore monotonicity can not be guaranteed. Also, it does not offer any useful functionality for systemd-journald.

None of the callers take advantage of this parameter, it's always NULL, this is just a private helper function to simplify the call sites so drop the template parameter altogether. If a caller emerges later who needs it, it can be restored.

2016-02-02journalctl: make "journalctl /dev/sda" workMichal Sekletar
Currently when journalctl is called with path to block device node we add following match _KERNEL_DEVICE=b$MAJOR:$MINOR. That is not sufficient to actually obtain logs about the disk because dev_printk() kernel helper puts to /dev/kmsg information about the device in following format, +$SUBSYSTEM:$ADDRESS, e.g. "+pci:pci:0000:00:14.0". Now we will walk upward the syspath and add match for every device in format produced by dev_printk() as well as match for its device node if it exists.
