# Change Log
|
|
|
|
All notable changes to CAPS will be documented in this file.
|
|
Please note that we have changed the date format from year-month-day
|
|
to year.dayofyear to be in sync with `caps -V`.
|
|
|
|
## 2025.232
|
|
|
|
- Fix data retrieval at the beginning of a year with archive files that start
|
|
after the requested start time but at the same day.
|
|
|
|
## 2025.199
|
|
|
|
- Fix station lookup in web application v2. This bug lead to stations symbols
|
|
placed in a arbitrarily fixed grid and wrong plots.
|
|
- Add preferred nodalplane to focalmechanism page in OriginLocatorView v2.
|
|
|
|
## 2025.135
|
|
|
|
- Fix datafile header CRC computation.
|
|
|
|
## 2025.128
|
|
|
|
- Relax NSLC uppercase requirement for FDSNWS dataselect request.
|
|
|
|
## 2025.112
|
|
|
|
- Fix crash in combination with `caps --read-only`.
|
|
|
|
## 2025.101
|
|
|
|
- Add option `AS.filebase.params.concurrency` to write to the archive
|
|
concurrently multi-threaded. This can improve performance with some
|
|
storage technologies such as SSD / NVMe under very high load or with
|
|
high latency storage devices such as network connected storages under
|
|
moderate load.
|
|
- Optimized write performance by reducing and combining page updates.
|
|
|
|
## 2024.290
|
|
|
|
- Add Option to purge data via CAPS protocol API. Only users with the `purge`
|
|
permission can delete data from archive.
|
|
|
|
## 2024.269
|
|
|
|
- Fixed crash on inserting data under some still unclear circumstances.
|
|
|
|
## 2024.253
|
|
|
|
- Add more robust checks to detect corrupted files caused by, e.g.
|
|
faulty storages or hardware failures/crashes. Corrupt files could have
|
|
caused segmentation faults of `caps`.
|
|
|
|
## 2024.215
|
|
|
|
- Fix webfrontend bug if `AS.http.fdsnws` is specified. This
|
|
bug prevented the webfrontend to load.

|
|
messages and log disconnection requests from the plugin to
|
|
INFO level.
|
|
|
|
## 2024.143
|
|
|
|
- Fix issue with merging raw records after a restart
|
|
|
|
## 2024.096

|
|
|
|
## 2023.321
|
|
|
|
- Decouple data disc storage from client notifications. This will increase
|
|
performance if many real-time clients are connected. A new parameter has
|
|
been added to control the size of the notification queue:
|
|
`AS.filebase.params.q`. The default value is 1000.
|
|
|
|
## 2023.320
|
|
|
|
- Add file storage optmization which might be useful if dealing with a large
|
|
amount of channels. In particular `AS.filebase.params.writeMetaOnClose` and
|
|
`AS.filebase.params.alignIndexPages` have been added in order to reduce the
|
|
I/O bandwidth.
|
|
- Add write thread priority option. This requires the user who is running
|
|
CAPS to be able to set rtprio, see limits.conf.

|
|
- Crash in combination with websocket data connections
|
|
|
|
## 2023.004
|
|
|
|
### Fixed
|
|
|
|
- Reload operation with respect to access changes. Recent versions
|
|
crashed under some circumstances.
|
|
|
|
## 2022.354
|
|
|
|
### Added
|
|
|
|
- Show connection statistics in the frontend
|
|
|
|
## 2022.349
|

|
|
|
### Fixed
|
|
|
|
- Fixed statistics calculation in `--read-only` mode.
|
|
|
|
## 2022.342
|
|
|
|
### Added
|
|
|
|
- Read optional index files per archive directory during startup which
|
|
allow to skip scanning the directory and only rely on the index information.
|
|
This can be useful if mounted read-only directories should be served and
|
|
skipped from possible scans to reduce archive scan time.
|
|
|
|
## 2022.341
|
|
|
|
### Changed
|
|
|
|
- Improve start-up logging with respect to archive scanning and setup.

All information go to the notice level and will be logged irrespective
|
|
of the set log level.
|
|
- Add configuration option to define the path of the archive log file,
|
|
`AS.filebase.logFile`.
|
|
|
|

|
|
with wildcard requests.
|
|
|
|
## 2022.333
|
|
|
|

|
|
|
|
## 2022.322
|
|
|
|
### Added
|
|
|
|
- Added system error message if a data file cannot be created.
|
|
- Try to raise ulimit to at least cached files plus opened files
|
|
and terminate if that was not successful.
|
|
|
|
## 2022.320
|
|
|
|
### Fixed
|
|
|
|
- Fixed storage of overlapping raw records which overlap with
|
|
gaps in a data file.
|
|
|
|
## 2022.314
|
|
|
|
### Fixed
|
|
|
|
- Fixed trimming of raw records while storing them. If some
|
|
samples were trimmed then sometimes raw records were merged
|
|
although the do not share a common end and start time.
|
|
|
|
## 2022.307
|
|
|
|
### Fixed
|
|
|
|
- Fixed deadlock in combination with server info queries
|
|
|
|
## 2022.284
|
|
|
|
### Fixed
|
|
|
|
- Fixed segment resolution evaluation in frontend
|
|
|
|
## 2022.278
|
|
|
|
### Fixed
|
|
|
|
- Fixed memory leak in combination with some gap requests
|
|
|
|
## 2022.269
|
|
|
|
### Fixed
|
|
|
|
- Memory leak in combination with request logs.
|
|
|
|
### Changed
|
|
|
|
- Removed user `FDSNWS` in order to allow consistent permissions
|
|
with other protocols. The default anonymous access is authenticated
|
|
as guest. Furthermore HTTP Basic Authentication can be used to
|
|
authenticate an regular CAPS user although that is not part of the
|
|
FDSNWS standard. This is an extension of CAPS.
|
|
|
|
If you have set up special permission for the FDSNWS user then you
|
|
have to revise them.
|
|
|
|
The rationale behind this change is (as stated above) consistency.
|
|
Furthermore the ability to configure access based on IP addresses
|
|
drove that change. If CAPS authenticates any fdsnws request as
|
|
user `FDSNWS` then IP rules are not taken into account. Only
|
|
anonymous requests are subject to IP based access rules. We do not
|
|
believe that the extra `FDSNWS` user added any additional security.
|
|
|
|
## 2022.265
|
|
|
|
### Fixed
|
|
|
|
- Crash in combination with MTIME requests.
|
|
|
|
## 2022.262
|
|
|
|
### Added
|
|
|
|
- Added modification time filter to stream requests. This allows to
|
|
request data and segment which were available at a certain time.
|
|
|
|
## 2022-09-06
|
|
|
|
### Improved
|
|
|
|
- Improved frontend performance with many thousands of channels and
|
|
high segmentation.
|
|
|
|
### Fixed
|
|
|
|
- Fixed time window trimming of raw records which prevented data delivery
|
|
under some very rare circumstances.
|
|
|
|
## 2022-09-02
|
|
|
|
### Added
|
|
|
|
- List RESOLUTION parameter in command list returned by HELP on client
|
|
interface.
|
|
|
|
## 2022-08-25
|
|
|
|
### Changed
|
|
|
|
- Allow floating numbers for slist format written by capstool.
|
|
|
|
## 2022-08-25
|
|
|
|
### Important
|
|
|
|
- Serve WebSocket requests via the regular HTTP interface. The
|
|
configuration variables `AS.WS.port` and `AS.WS.SSL.port` have
|
|
been removed. If WebSocket access is not desired then the HTTP
|
|
interface must be disabled.
|
|
- Reworked the HTTP frontend which now provides display of channel segments,
|
|
cumulative station and network views and a view with multiple traces.
|
|
- In the reworked frontend, the server statistics are only available to users
|
|
which are member of the admin group as defined by the access control file
|
|
configured in `AS.auth.basic.users.passwd`.
|
|
|
|
## 2022-08-16
|
|
|
|
### Added
|
|
|
|
- Open client files read-only and only request write access if the index
|
|
needs to be repaired or other maintenance operations must be performed.
|
|
This makes CAPS work on a read-only mounted file system.
|
|
|
|
## 2022-07-12
|
|
|
|
### Fixed
|
|
|
|
- Fixed HELI request with respect to sampling rate return value.
|
|
It returned the underlying stream sampling rate rather than 1/1.
|
|
|
|
## 2022-06-10
|
|
|
|
### Fixed
|
|
|
|
- Improve bad chunk detection in corrupt files. Although CAPS is
|
|
pretty stable when it comes to corrupted files other tools might
|
|
not. This improvement will trigger a file repair if a bad chunk
|
|
has been detected.
|
|
|
|
## 2022-06-07
|
|
|
|
### Fixed
|
|
|
|
- Infinite loop if segments with resolution >= 1 were requested.
|
|
|
|
## 2022-05-30
|
|
|
|
### Added
|
|
|
|
- Add "info server" request to query internal server state.
|
|
|
|
## 2022-05-18
|
|
|
|
### Fixed
|
|
|
|
- Fix possible bug in combination with websocket requests. The
|
|
issue exhibits as such as the connection does not respond anymore.
|
|
Closing and reopening the connection would work.
|
|
|
|
## 2022-05-09
|
|
|
|
### Added
|
|
|
|
- Add gap/segment query.
|
|
|
|
## 2022-04-26
|
|
|
|
### Important
|
|
|
|
- With this release we have split the server and the tools
|
|
|
|
- riffdump
|
|
- riffsniff
|
|
- rifftest
|
|
- capstool
|
|
|
|
into separate packages. We did this because for some use cases
|
|
it make sense to install only these tools. The new package is
|
|
called `caps-tools` and activated for all CAPS customers.
|
|
|
|
## 2022-03-28
|
|
|
|
### Changed
|
|
|
|
- Update command-line help for capstool.
|
|
|
|
## 2022-03-03
|
|
|
|
### Added
|
|
|
|
- Log plugin IP and port on accept.
|
|
- Log plugin IP and port on package store error.
|
|
|
|
## 2021-12-20
|
|
|
|
### Added
|
|
|
|
- Explain record sorting in capstool documentation.
|
|
|
|
## 2021-11-09
|
|
|
|
### Fixed
|
|
|
|
- Fixed helicorder request in combination with filtering. The
|
|
issue caused wrong helicorder min/max samples to be returned.
|
|
|
|
## 2021-10-26
|
|
|
|
### Fixed
|
|
|
|
- Fixed data extraction for the first record if it does not
|
|
intersect with the requested time window.
|
|
|
|
## 2021-10-19
|
|
|
|
### Changed
|
|
|
|
- Update print-access help page entry
|
|
- Print help page in case of unrecognized command line options
|
|
|
|
### Fixed
|
|
|
|
- Do not print archive stats when the help page or version information is
|
|
requested
|
|
|
|
## 2021-09-20
|
|
|
|
### Fixed
|
|
|
|
- Fixed crash if an FDSNWS request with an empty compiled channel list has been
|
|
made
|
|
|
|
## 2021-09-17
|
|
|
|
### Added
|
|
|
|
- New config option `AS.filebase.purge.referenceTime` defining which reference
|
|
time should be used while purge run. Available are:
|
|
|
|
- EndTime: The purge run uses the end time per stream as reference time.
|
|
- Now: The purge run uses the current time as reference time.
|
|
|
|
By default the purge operation uses the stream end time as reference time.
|
|
To switch to **Now** add the following entry to the caps configuration.
|
|
|
|
```config
|
|
AS.filebase.purge.referenceTime = Now
|
|
```
|
|
|
|
## 2021-05-03
|
|
|
|
### Changed
|
|
|
|
- Log login and logout attempts as well as blocked stream requests to request
|
|
log.
|
|
- Allow whitespaces in passwords.
|
|
|
|
## 2021-04-15
|
|
|
|
### Fixed
|
|
|
|
- Rework CAPS access rule evaluation.
|
|
|
|
### Changed
|
|
|
|
- Comprehensive rework of CAPS authentication feature documentation.
|
|
|
|
## 2021-03-11
|
|
|
|
### Important
|
|
|
|
- Reworked data file format. An high performance index has been added to the
|
|
data files which require an conversion of the data files. See CAPS
|
|
documentation about upgrading. The conversion is done transparently in the
|
|
background but could affect performance while the conversion is in progress.
|
|
|
|
## 2020-10-12
|
|
|
|
### Added
|
|
|
|
- Provide documentation of the yet2caps plugin.
|
|
|
|
## 2020-09-04
|
|
|
|
### Fixed
|
|
|
|
- Fixed gaps in helicorder request.
|
|
|
|
## 2020-07-01
|
|
|
|
### Fixed
|
|
|
|
- Don't modify stream start time if the assoicated data file
|
|
couldn't deleted while purge run. This approach makes sure that
|
|
stream start time and the data files are kept in sync.
|
|
|
|
## 2020-02-24
|
|
|
|
### Added
|
|
|
|
- Extended purge log. The extended purge log can be enabled with
|
|
the configuration parameter `AS.logPurge`. This feature is not enabled
|
|
by default.
|
|
|
|
### Changed
|
|
|
|
- Log maximum number of days to keep data per stream at start.
|
|
|
|
## 2020-01-27
|
|
|
|
### Fixed
|
|
|
|
- Typo in command line output.
|
|
|
|
## 2019-11-26
|
|
|
|
### Added
|
|
|
|
- Added new command line option `configtest that runs a
|
|
configuration file syntax check. It parses the configuration
|
|
files and either reports Syntax OK or detailed information
|
|
about the particular syntax error.
|
|
- Added Websocket interface which accepts HTTP connections
|
|
(e.g. from a web browser) and provides the CAPS
|
|
protocol via Websockets. An additional configuration will
|
|
be necessary:
|
|
|
|
```config
|
|
AS.WS.port = 18006
|
|
# Provides the Websocket interface via secure sockets layer.
|
|
# The certificate and key used will be read from
|
|
# AS.SSL.certificate and AS.SSL.key.
|
|
AS.WS.SSL.port = 18007
|
|
```
|
|
|
|
### Changed
|
|
|
|
- Simplified the authorization configuration. Instead of using one
|
|
login file for each CAPS interface we read the authentication
|
|
information from a shadow file. The file contains one line
|
|
per user where each line is of format "username:encrypted_pwd".
|
|
To encrypt a password mkpasswd can be used. It is recommended to
|
|
apply a strong algorithm such as sha-256 or sha-512. The command
|
|
"user=sysop pw=`mkpasswd -m sha-512` && echo $user:$pw"
|
|
would generate a line for e.g. user "sysop". The shadow
|
|
file can be configured with the config option `AS.users.shadow`.
|
|
|
|
Example:
|
|
|
|
```config
|
|
# The username is equal to the password
|
|
test:$6$jHt4SqxUerU$pFTb6Q9wDsEKN5yHisPN4g2PPlZlYnVjqKFl5aIR14lryuODLUgVdt6aJ.2NqaphlEz3ZXS/HD3NL8f2vdlmm0
|
|
user1:$6$mZM8gpmKdF9D$wqJo1HgGInLr1Tmk6kDrCCt1dY06Xr/luyQrlH0sXbXzSIVd63wglJqzX4nxHRTt/I6y9BjM5X4JJ.Tb7XY.d0
|
|
user2:$6$zE77VXo7CRLev9ly$F8kg.MC8eLz.DHR2IWREGrSwPyLaxObyfUgwpeJdQfasD8L/pBTgJhyGYtMjUR6IONL6E6lQN.2QLqZ5O5atO/
|
|
```
|
|
|
|
In addition to user authentication user access control properties are defined
|
|
in a passwd file. It can be configured with the config option
|
|
`AS.users.passwd`. Each line of the file contains a user name or a group
|
|
id and a list of properties in format "username:prop1,prop2,prop3".
|
|
Those properties are used to grant access to certain functionalities.
|
|
Currently the following properties are supported by CAPS: read, write.:
|
|
"read and write.".
|
|
By default a anonymous user with read and write permissions exists. Groups use
|
|
the prefix **%** so that they are clearly different from users.
|
|
|
|
Example:
|
|
|
|
```config
|
|
user1: read,write
|
|
%test: read
|
|
```
|
|
|
|
The group file maps users to different groups. Each line of the file maps
|
|
a group id to a list of user names. It can be configured with the config
|
|
option `AS.users.group`.
|
|
|
|
Example:
|
|
|
|
```config
|
|
test: user2
|
|
```
|
|
|
|
With the reserved keyword **ALL** a rule will be applied to all users.
|
|
|
|
Example:
|
|
|
|
```config
|
|
STATIONS.DENY = all
|
|
STATIONS.AM.ALLOW = user1
|
|
```
|
|
|
|
- We no longer watch the status of the inventory and the access file with
|
|
Inotify because it could be dangerous in case of an incomplete saved
|
|
configuration. A reload of the configuration can be triggered by sending a
|
|
SIGUSR1 signal to the CAPS process. Example:
|
|
|
|
```bash
|
|
kill -SIGUSR1 <pid>
|
|
```
|
|
|
|
CAPS reloads the following files, if necessary:
|
|
|
|
- shadow,
|
|
- passwd,
|
|
- access list,
|
|
- inventory.

## 2019-10-15
|
|
|
|
### Changed
|
|
|
|
- Run archive clean up after start and every day at midnight(UTC).
|
|
|
|
## 2019-10-01
|
|
|
|
### Changed
|
|
|
|
- Increase shutdown timeout to 60 s.
|
|
|
|
## 2019-05-08
|
|
|
|
### Fixed
|
|
|
|
- Fixed potential deadlock in combination with inventory updates.
|
|
|
|
## 2019-04-23
|
|
|
|
### Fixed
|
|
|
|
- Improved plugin data scheduling which could have caused increased delays
|
|
of data if one plugin transmits big amounts of data through a low latency
|
|
network connection, e.g. localhost.
|
|
|
|
## 2019-04-08
|
|
|
|
### Added
|
|
|
|
- Added new config option `AS.filebase.purge.initIdleTime` that
|
|
allows to postpone the initial purge process up to n seconds. Normally
|
|
after a start the server tries to catch up all data which
|
|
might be an IO intensive operation. In case of a huge archive the purge
|
|
operation slow downs the read/write performance of the system too. To
|
|
reduce the load at start it is a good idea to postpone this operation.
|
|
|
|
## 2019-03-29
|
|
|
|
### Added
|
|
|
|
- Added index file check during archive scan and rebuild them
|
|
if corrupt. The lack of a check sometimes caused CAPS to
|
|
freeze while starting up.
|
|
|
|
## 2018-12-11
|
|
|
|
### Added
|
|
|
|
- Added support for SC3 schema 0.11.
|
|
|
|
## 2018-10-18
|
|
|
|
### Fixed
|
|
|
|
- Spin up threads correctly in case of erroneous configuration
|
|
during life reconfiguration.
|
|
|
|
## 2018-10-17
|
|
|
|
### Fixed
|
|
|
|
- Reinitalize server ports correctly after reloading the access list. This
|
|
was not a functional bug, only a small memory leak.
|
|
|
|
## 2018-09-14
|
|
|
|
### Fixed
|
|
|
|
- High IO usage while data storage purge. In worst case the purge operation
|
|
could slow down the complete system so that incoming packets could not be
|
|
handled anymore.
|
|
|
|
## 2018-09-05
|
|
|
|
### Added
|
|
|
|
- Access rule changes do not require a restart of the server anymore.
|
|
|
|
## 2018-08-29
|
|
|
|
### Changed
|
|
|
|
- Assigned human readable descriptions to threads. Process information tools
|
|
like top or htop can display this information.
|
|
|
|
## 2018-08-08
|
|
|
|
### Changed
|
|
|
|
- Reduced server load for real-time client connections.
|
|
|
|
## 2018-05-30
|
|
|
|
### Fixed
|
|
|
|
- Fixed unexpected closed SSL connections.
|
|
|
|
## 2018-05-25
|
|
|
|
### Fixed
|
|
|
|
- Fixed high load if many clients request many streams in real-time.
|
|
|
|
## 2018-05-18
|
|
|
|
### Added
|
|
|
|
- Add option to log anonymous IP addresses.
|
|
|
|
## 2018-04-17
|
|
|
|
### Fixed
|
|
|
|
- Improved handling of incoming packets to prevent packet loss to subscribed
|
|
sessions in case of heavy load.
|
|
|
|
## 2018-03-08
|
|
|
|
### Fixed
|
|
|
|
- Fixed access list evaluator. Rather than replacing general rules with concrete
|
|
rules they are now merged hierarchically.
|
|
|
|
## 2018-02-13
|
|
|
|
### Added
|
|
|
|
- Restrict plugin stream codes to [A-Z][a-z][0-9][-_] .
|
|
|
|
## 2018-01-31
|
|
|
|
### Changed
|
|
|
|
- CAPS archive log will be removed at startup and written at shutdown. With
|
|
this approach we want to force a rescan of the complete archive in case of
|
|
an unexpected server crash.
|
|
|
|
## 2018-01-30
|
|
|
|
### Fixed
|
|
|
|
- Fixed parameter name if HTTP SSL port, which should be `AS.http.SSL.port`
|
|
but was `AS.SSL.http.port`.
|
|
|
|
## 2018-01-29
|
|
|
|
### Fixed
|
|
|
|
- Fixed caps protocol real time handler bug which caused gaps on client-side
|
|
when retrieving real time data.
|
|
|
|
## 2018-01-26
|
|
|
|
### Changed
|
|
|
|
- Log requests per CAPS server instance.
|
|
|
|
### Fixed
|
|
|
|
- Improved data scheduler to hopefully prevent clients from stalling the
|
|
plugin input connections.
|
|
|
|
## 2018-01-02
|
|
|
|
### Fixed
|
|
|
|
- Fixed bug in combination with SSL connections that caused CAPS to not
|
|
accept any incoming connections after some time.
|
|
|
|
## 2017-11-15
|
|
|
|
### Added
|
|
|
|
- Added option `AS.inventory` which lets CAPS read an SC3 inventory XML
|
|
file to be used together with WWS requests to populate channel geo locations
|
|
which will enable e.g. the map feature in Swarm.
|
|
|
|
## 2017-11-14
|
|
|
|
### Fixed
|
|
|
|
- Data store start time calculation in case of the first record start time is
|
|
greater than the requested one.
|
|
|
|
## 2017-11-08
|
|
|
|
### Fixed
|
|
|
|
- WWS Heli request now returns correct timestamps for data with gaps.
|
|
|
|
## 2017-10-13
|
|
|
|
### Fixed
|
|
|
|
- FDSN request did not return the first record requested.
|
|
|
|
## 2017-08-30
|
|
|
|
### Fixed
|
|
|
|
- Segmentation fault caused by invalid FDSN request.
|
|
- Timing bug in the CAPS WWS protocol implementation.
|
|
|
|
## 2017-06-15
|
|
|
|
### Added
|
|
|
|
- Add `AS.minDelay` which delays time window requests for the specified
|
|
number of seconds. This parameter is only effective with FDSNWS and WWS.
|
|
|
|
## 2017-05-30
|
|
|
|
### Feature
|
|
|
|
- Add experimental Winston Wave Server(WWS) support. This feature is disabled
|
|
by default.
|
|
|
|
## 2017-05-09
|
|
|
|
### Feature
|
|
|
|
- Add FDSNWS dataselect support for archives miniSEED records. This
|
|
support is implicitely enabled if HTTP is activated.
|
|
|
|
## 2017-05-03
|
|
|
|
### Feature
|
|
|
|
- Support for SSL and authentication in AS, client and HTTP transport.
|
|
|
|
## 2017-03-24
|
|
|
|
### Fixed
|
|
|
|
- MSEED support.
|
|
|
|
## 2017-03-09
|
|
|
|
### Changed
|
|
|
|
- Moved log output that the index was reset and that an incoming
|
|
record has not ignored to debug channel.
|
|
|
|
## 2016-06-14
|
|
|
|
### Added
|
|
|
|
- Added option `AS.clientBufferSize` to configure the buffer
|
|
size for each client connection. The higher the buffer size
|
|
the better the request performance.
|
|
|
|
## 2016-06-09
|
|
|
|
### Added
|
|
|
|
- Added out-of-order requests for clients. The rsas plugin with
|
|
version >= 0.6.0 supports requesting out-of-order packets with
|
|
parameter `ooo`, e.g. `caps://localhost?ooo`.
|
|
- Improved record insertion speed with out-of-order records.
|
|
|
|
## 2016-03-09
|
|
|
|
### Fixed
|
|
|
|
- Low packet upload rate.
