Description:
|
I'm not 100% sure but I think currently the polling for VCS changes for the build trigger currently uses a (UTC) date/time reference -since which is the time stamp of the last polling (not the last executed build).
Unfortunately this seems not compatible with ClearCase MultiSite.
ClearCase MultiSite does a replication between servers at different locations at fixed intervals (for example once each hour). This means a change a location X will, in worst case, be visible at location Y only after 1 hour. But the time stamp of the change will still be the original one (i.e. when the check-in was actually done, in example a time > 1 hour ago).
Thus, with the time reference to last poll most of the changes coming in from a remote server will not be considered by VCS polling.
Example flow (VCS polling done at a H/10 * * * * schedule at location)
| Location |
Time |
Action |
| X |
10:00 |
Checkin <FILE-1> |
| Y |
10:04 |
VCS Poll (-since 9:54). No change seen as no MultiSite Sync was done. |
| X |
10:07 |
VCS Poll (-since 9:57). Change <FILE-1> seen. Build at location X triggered. |
| X and Y |
... |
Several further VCS polls. No changes detected. |
| Y |
10:54 |
VCS Poll (-since 10:44). No change seen as no MultiSite Sync was done. |
| X<->Y |
10:58 |
ClearCase MultiSite Replication performed and completed. |
| Y |
11:04 |
VCS Poll (-since 10:54). PROBLEM Change of <FILE-1> at 10:00 is now replicated but not seen due to -since 10:54 but the change actually is recorded in ClearCase with time stamp 10:00. |
